Recommended Products for This Recipe
After making this recipe dozens of times, I’ve found a few products that really make a difference in the final result and the cooking process.
1. Crock-Pot 7-Quart Programmable Slow Cooker
This is my go-to slow cooker because it’s large enough to fit six stuffed peppers comfortably without crowding.
The programmable timer automatically switches to warm when cooking is done, so your peppers won’t overcook if you’re running late.
2. San Marzano Crushed Tomatoes
The quality of your tomatoes makes a huge difference in this recipe.
San Marzano tomatoes have a naturally sweet flavor and low acidity that creates the perfect sauce for these stuffed peppers without being too tangy.
3. Minute Ready to Serve White Rice
For the most foolproof results, I use parboiled or instant rice that cooks perfectly in the slow cooker without getting mushy.
This saves you from having to cook rice separately and keeps the texture just right.
4. OXO Good Grips Stuffing Spoon
This wide, flexible spoon makes it so much easier to pack the filling tightly into the peppers without spilling.
The narrow handle fits perfectly inside the peppers, and the flexible edge helps scrape every bit of filling from your bowl.
Step-by-Step Instructions: How to Make Crockpot Stuffed Bell Peppers
Follow these detailed steps to create perfectly cooked stuffed peppers that your whole family will love.
Even if you’re new to using a slow cooker, these instructions will guide you through every part of the process.
1. Prepare the Bell Peppers
- Wash the bell peppers under cold running water and pat them dry with a clean towel.
- Using a sharp knife, carefully cut off the top of each pepper about ½ inch from the stem, creating a flat opening at the top.
- Reach inside each pepper and pull out the core, seeds, and white ribs. You can use a spoon to help scrape out any stubborn bits.
- Dice the pepper tops (excluding the stems) into small pieces and set aside for the filling.
- Stand the hollowed peppers upright and check that they sit level. If needed, trim a tiny bit from the bottom so they stand without tipping.
- Spray the inside of your slow cooker with cooking spray or brush lightly with olive oil to prevent sticking.
2. Brown the Ground Beef and Aromatics
- Heat 2 tablespoons of olive oil in a large skillet over medium-high heat until shimmering.
- Add the diced onion and the chopped pepper tops to the skillet. Cook for 4-5 minutes, stirring occasionally, until the onion becomes translucent and softened.
- Add the minced garlic to the skillet and cook for another 30 seconds, stirring constantly to prevent burning.
- Add the ground beef to the skillet, breaking it up with a wooden spoon or spatula into small crumbles.
- Season the beef with salt, black pepper, Italian seasoning, and crushed red pepper flakes (if using).
- Cook the beef for 8-10 minutes, stirring frequently and breaking up any large chunks, until no pink remains.
- Once fully cooked, drain any excess fat from the skillet by carefully tilting it and spooning out the grease, or pour the mixture into a colander.
- Return the drained beef mixture to the skillet.
3. Prepare the Filling Mixture
- Add the uncooked rice to the skillet with the cooked beef mixture and stir well to combine.
- Pour in the Worcestershire sauce and stir to coat all the ingredients evenly.
- Add half of the crushed tomatoes (about 1½ cups) and half of the diced tomatoes (about ¾ cup) to the beef and rice mixture. Stir everything together thoroughly.
- Add 1 cup of the shredded mozzarella cheese to the mixture and stir until the cheese is evenly distributed throughout.
- Taste the filling and adjust seasoning if needed with additional salt, pepper, or Italian seasoning.
- Remove the skillet from the heat and let the filling cool slightly for easier handling (about 5 minutes).

4. Make the Sauce for the Slow Cooker
- In a large mixing bowl, combine the remaining crushed tomatoes and diced tomatoes.
- Add the beef broth to the tomato mixture.
- Stir in the tomato paste until it’s completely dissolved and the sauce is smooth.
- Add a pinch of salt and pepper to the sauce and mix well.
- Ladle approximately 1 cup of this sauce into the bottom of the prepared slow cooker, spreading it evenly across the base.
- This sauce layer prevents the peppers from sticking and keeps them moist during cooking.
5. Stuff the Peppers
- Using a large spoon or ice cream scoop, carefully fill each hollowed pepper with the beef and rice mixture.
- Pack the filling down gently with the back of the spoon as you go to eliminate air pockets and fit more filling inside.
- Fill each pepper almost to the top, but leave about ¼ inch of space at the rim since the rice will expand as it cooks.
- Make sure the filling is compact and tightly packed to ensure even cooking throughout.
- If you have any leftover filling after stuffing all six peppers, you can add it to the bottom of the slow cooker around the peppers.
6. Arrange Peppers in the Slow Cooker
- Carefully place each stuffed pepper upright in the slow cooker on top of the sauce layer.
- Arrange the peppers so they’re standing as upright as possible. They may lean against each other slightly, which is fine.
- Try to fit all peppers in a single layer if your slow cooker is large enough. If needed, you can stack one or two peppers on top, but the bottom layer will cook more evenly.
- Ensure the peppers are not touching the sides of the slow cooker too much, as this can cause uneven cooking or sticking.
7. Add Remaining Sauce
- Ladle the remaining tomato and broth sauce evenly over the top of each stuffed pepper.
- Try to pour some sauce directly into the opening of each pepper to keep the filling moist.
- Spoon sauce around the sides of the peppers as well, making sure they’re surrounded by liquid.
- The peppers should be about halfway submerged in the sauce for optimal cooking.
8. Cook the Stuffed Peppers
- Place the lid securely on the slow cooker.
- Set the slow cooker to LOW and cook for 5-6 hours, or set to HIGH and cook for 2½-3 hours.
- Resist the urge to lift the lid during cooking, as this releases heat and extends cooking time by 15-20 minutes each time you peek.
- The peppers are done when they’re tender enough to easily pierce with a fork and the rice filling is fully cooked through.
- You can test doneness by inserting a fork into the thickest part of a pepper and the filling. If it goes in easily and the rice is tender, they’re ready.
- If the filling seems dry or the rice isn’t quite done, you can add an extra ¼ cup of beef broth and continue cooking for another 30 minutes.
9. Add Cheese and Serve
- Once the peppers are fully cooked, sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the top of each pepper.
- Replace the lid and let the residual heat melt the cheese, about 5-10 minutes. You can also turn the slow cooker to HIGH for faster melting.
- Carefully remove each pepper from the slow cooker using a large spoon or tongs, being gentle so they don’t fall apart.
- Place each stuffed pepper on a serving plate.
- Ladle some of the sauce from the bottom of the slow cooker over each pepper for extra flavor and moisture.
- Garnish with freshly chopped parsley before serving.
- Serve immediately while hot.
Tips for The Best Crockpot Stuffed Bell Peppers
These tried-and-true tips will help you make the most delicious stuffed peppers every time you prepare this recipe.
- Choose the Right Rice: Use parboiled, instant, or quick-cooking rice for best results. Long-grain rice takes too long to cook and may remain hard or absorb too much liquid, making the filling dry.
- Don’t Skip Browning the Meat: While you can use raw meat, browning it first gives the filling a better texture and deeper flavor. It also allows you to drain excess fat before stuffing.
- Add Sauce to the Bottom First: This crucial step prevents the peppers from sticking to the slow cooker and burning on the bottom. I learned this the hard way during my first attempt!
- Pack the Filling Tightly: Air pockets in the filling can cause uneven cooking. Use the back of a spoon to press down the filling as you stuff each pepper.
- Select Similar-Sized Peppers: Try to choose peppers that are roughly the same size so they cook evenly at the same rate.
- Cut a Small Slice from the Bottom if Needed: If your peppers won’t stand upright, carefully trim a tiny bit from the bottom (without cutting through to the inside) to create a flat base.
- Monitor the Liquid Level: If you notice the sauce is evaporating too quickly during cooking, add a bit more broth or water to prevent the peppers from drying out.
- Avoid Overcooking: Peppers cooked too long will become mushy and fall apart. Start checking them at the minimum cooking time.
- Use a Meat Thermometer: The internal temperature of the filling should reach 165°F to ensure the meat is fully cooked and safe to eat.
- Let Them Rest: Allow the stuffed peppers to sit for 5 minutes after removing from the slow cooker. This helps the filling set and makes them easier to serve.

Serving Suggestions
These stuffed peppers are hearty enough to serve as a complete meal on their own, but pairing them with complementary sides makes for an even more satisfying dinner spread.
- Crusty Bread: Serve with warm garlic bread or a crusty baguette to soak up all the delicious tomato sauce from the bottom of the slow cooker.
- Fresh Green Salad: A crisp salad with mixed greens, cucumber, and tomatoes dressed with a light vinaigrette balances the richness of the stuffed peppers perfectly.
- Garlic Bread: Nothing beats homemade garlic bread on the side to round out this Italian-inspired meal.
- Roasted Vegetables: Serve alongside roasted zucchini, asparagus, or green beans for extra vegetables.
- Mashed Potatoes: Creamy Mashed Potato Casserole makes a wonderful accompaniment for a truly filling meal.
- Coleslaw: A tangy coleslaw provides a nice contrast to the savory peppers and adds a refreshing crunch.
- Rice Pilaf: If you want to stretch the meal further, serve extra rice pilaf on the side for those with heartier appetites.
- Sautéed Spinach or Kale: Quick-sautéed greens with garlic add a nutritious and flavorful side dish.
Variations of Crockpot Stuffed Bell Peppers
One of the best things about this recipe is how versatile it is. You can easily customize it to suit different dietary preferences or to use what you have on hand.
- Turkey or Chicken Stuffed Peppers: Swap the ground beef for ground turkey or chicken for a leaner option. The cooking time remains the same.
- Mexican-Style Stuffed Peppers: Use taco seasoning instead of Italian seasoning, replace the tomatoes with salsa and enchilada sauce, and add black beans and corn to the filling. Top with Mexican cheese blend and serve with sour cream and guacamole.
- Vegetarian Stuffed Peppers: Omit the meat entirely and double up on beans (black beans, kidney beans, or pinto beans) for protein. Add extra vegetables like zucchini, mushrooms, or corn.
- Italian Sausage Variation: Replace half or all of the ground beef with Italian sausage (sweet or spicy) for more robust flavor.
- Quinoa Stuffed Peppers: Substitute quinoa for rice for a protein-packed, gluten-free alternative. Use the same amount and cooking time.
- Cauliflower Rice Low-Carb Version: For a keto-friendly option, use riced cauliflower instead of regular rice. Add it to the filling mixture without pre-cooking.
- Cheesy Stuffed Peppers: Mix additional cheeses like cheddar, parmesan, or pepper jack into the filling for an ultra-cheesy version.
- Asian-Inspired Stuffed Peppers: Use ground pork, add soy sauce, ginger, garlic, and sesame oil to the filling. Mix in cooked rice and top with green onions and sesame seeds.
- Mediterranean Stuffed Peppers: Add feta cheese, olives, sun-dried tomatoes, and oregano to the filling. Use lamb instead of beef for authentic Greek flavor.
- Spicy Stuffed Peppers: Add diced jalapeños to the filling, use pepper jack cheese, and include cayenne pepper or hot sauce for extra heat.

Storage and Reheating
Proper storage ensures your leftover stuffed peppers taste just as delicious as they did fresh from the slow cooker.
- Refrigerator Storage: Allow the stuffed peppers to cool completely to room temperature (within 2 hours of cooking). Transfer them to an airtight container or wrap each pepper individually in plastic wrap or aluminum foil. Store in the refrigerator for up to 4 days.
- Freezer Storage: These stuffed peppers freeze beautifully for meal prep. Wrap each cooled pepper tightly in plastic wrap, then again in aluminum foil or place in freezer-safe bags. Label with the date and freeze for up to 3 months. For best results, freeze the peppers without the cheese topping and add fresh cheese when reheating.
- Reheating in Microwave: Place one pepper on a microwave-safe plate, cover with a damp paper towel, and microwave on high for 2-3 minutes, or until heated through to an internal temperature of 165°F.
- Reheating in Oven: Preheat your oven to 350°F. Place the peppers in a baking dish, add a splash of water or broth to the bottom to prevent drying, cover with foil, and bake for 25-30 minutes until hot throughout.
- Reheating from Frozen: For frozen peppers, thaw overnight in the refrigerator first for best results. You can also reheat directly from frozen in the oven at 350°F for 45-50 minutes (covered with foil), though the texture may be slightly softer.
- Storing the Sauce Separately: If you have extra sauce from the slow cooker, store it in a separate airtight container in the refrigerator for up to 5 days. Reheat and drizzle over the peppers when serving leftovers.

Health Benefits of Key Ingredients
This recipe isn’t just delicious—it’s also packed with nutritious ingredients that support your overall health and wellbeing.
- Bell Peppers: Exceptionally high in vitamin C (one pepper provides more than twice your daily requirement), bell peppers are powerful antioxidants that support immune function and skin health. They also contain vitamin A, which promotes eye health and vision.
- Ground Beef: An excellent source of high-quality protein, iron, zinc, and vitamin B12. The iron in beef is heme iron, which is more easily absorbed by the body than the iron found in plant sources. This helps prevent anemia and supports energy production.
- Tomatoes: Rich in lycopene, a powerful antioxidant linked to reduced risk of heart disease and certain cancers. Tomatoes also provide vitamin C, potassium, and folate. Cooking tomatoes actually increases the bioavailability of lycopene, making this dish even more beneficial.
- Garlic and Onions: Both contain sulfur compounds that have anti-inflammatory and immune-boosting properties. Garlic specifically has been shown to support heart health and may help lower blood pressure and cholesterol levels.
- Rice: Provides energy through complex carbohydrates and contains small amounts of protein and fiber. White rice is easily digestible and can be a good source of folate and other B vitamins when enriched.
- Mozzarella Cheese: Provides calcium for strong bones and teeth, as well as protein for muscle maintenance. It also contains probiotics that support gut health and phosphorus for bone health.
- Olive Oil: A heart-healthy fat rich in monounsaturated fatty acids and antioxidants that support cardiovascular health and reduce inflammation throughout the body.
FAQs About Crockpot Stuffed Bell Peppers
1. Do I need to cook the rice before stuffing the peppers?
No, you don’t need to pre-cook the rice when making crockpot stuffed peppers. The rice will cook perfectly inside the peppers during the slow cooking process.
Just make sure to use quick-cooking or parboiled rice rather than regular long-grain rice for the best texture and to ensure it cooks through completely in the allotted time.
2. Can I use raw ground beef instead of browning it first?
While you can technically use raw ground beef, I highly recommend browning it first for several important reasons.
Browning allows you to drain excess fat, which prevents your peppers from becoming greasy.
It also develops better flavor through the Maillard reaction and gives the filling a more appealing texture rather than the dense, meatloaf-like consistency you get with raw meat.
The extra 10 minutes of browning is well worth it for the improved results.
3. Why are my stuffed peppers watery?
Watery stuffed peppers usually result from too much liquid in the slow cooker or using regular long-grain rice that hasn’t absorbed enough moisture.
Make sure you’re using the correct amount of sauce as specified in the recipe and avoid adding extra liquid.
Using parboiled or instant rice helps because these varieties absorb more liquid during cooking.
If your peppers are too watery, you can remove the lid for the last 30 minutes of cooking to allow some liquid to evaporate, or drain off excess liquid before serving.
4. How do I prevent the peppers from falling apart in the slow cooker?
Choose firm, fresh peppers without soft spots or blemishes, as these will hold their shape better during the long cooking time.
Avoid overcooking by checking the peppers at the minimum suggested cooking time rather than letting them go longer.
When removing the peppers from the slow cooker, use a large slotted spoon or spatula to support the bottom of each pepper, and use tongs to steady the top if needed.
Handle them gently and they should stay intact.
5. Can I make stuffed peppers in advance?
Absolutely! You can prep the stuffed peppers up to 24 hours ahead of time.
Simply prepare the filling, stuff the peppers, and arrange them in the slow cooker insert. Cover tightly with plastic wrap and refrigerate the entire insert overnight.
The next morning, remove the plastic wrap, place the insert in the slow cooker base, add the sauce, and cook as directed. This makes busy weeknight dinners incredibly easy.
