Step-by-Step Instructions: How to Make Stuffed Pepper Casserole
Follow these detailed steps to create a perfectly cooked casserole with tender vegetables and flavorful rice. Take your time with the browning step for the best results.
1. Prepare Your Ingredients
Before you start cooking, get everything ready to make the process smooth and efficient.
- Dice all four bell peppers into bite-sized pieces, about 1/2 inch
- Finely chop the onion into small pieces
- Mince the garlic cloves until they’re very fine
- Cook your rice according to package directions and set aside
- Measure out all your spices and seasonings
- Have your tomato products opened and ready
- Shred the mozzarella cheese if not using pre-shredded
- Preheat your oven to 350°F
2. Brown the Ground Beef
This step builds the foundation of flavor for your entire casserole.
- Heat your large skillet or Dutch oven over medium-high heat
- Add the 2 lbs of ground beef to the hot pan
- Break up the meat with a wooden spoon as it cooks
- Season the beef with salt and pepper while browning
- Cook for 8-10 minutes until the meat is completely browned with no pink remaining
- Drain excess fat if needed, leaving about 1 tablespoon in the pan for flavor
3. Cook the Vegetables
The vegetables need time to soften and release their natural sweetness.
- Add the diced onion to the browned beef
- Stir the onion into the meat and cook for 3-4 minutes until it becomes translucent
- Add the diced bell peppers to the pan
- Cook the peppers with the meat and onion for 5-6 minutes, stirring occasionally
- The peppers should start to soften but still have some crunch
- Add the minced garlic and cook for 1 minute more, stirring constantly to prevent burning
- The mixture should smell fragrant and aromatic
4. Add the Tomatoes and Seasonings
Now we build the rich, savory sauce that brings everything together.
- Pour in the entire can of crushed tomatoes
- Add the full can of tomato sauce to the skillet
- Sprinkle in the 1 tablespoon of Italian seasoning
- Add the 1 teaspoon of paprika
- Season with additional salt and black pepper to taste
- Stir everything together until well combined
- Let the mixture simmer for 2-3 minutes to blend the flavors
5. Add Rice and Broth
The rice will absorb all the delicious flavors as it finishes cooking.
- Stir in your 2 cups of cooked white rice
- Pour in the 2 cups of beef broth
- Mix everything thoroughly so the rice is evenly distributed
- Bring the mixture to a gentle simmer
- Reduce heat to medium-low and let it cook for 5 minutes
- The mixture should be slightly soupy at this point
- Add 1 cup of the shredded mozzarella cheese and stir it in until melted
6. Transfer to Baking Dish
Moving the casserole to a baking dish ensures even cooking in the oven.
- Spray your 9×13-inch baking dish with cooking spray
- Carefully transfer the entire mixture from the skillet to the baking dish
- Spread it out evenly with a spatula
- Make sure the rice is distributed throughout
- The casserole should fill the dish to about 2 inches deep
- Cover the baking dish tightly with aluminum foil
7. Bake the Casserole
The oven time allows all the flavors to meld together perfectly.
- Place the covered baking dish in your preheated 350°F oven
- Bake for 25-30 minutes until hot and bubbly
- The edges should be gently bubbling when you peek under the foil
- Remove the foil carefully to avoid steam burns
- Sprinkle the remaining 1 cup of mozzarella cheese evenly over the top
- Return to the oven uncovered for 5-7 minutes until the cheese melts and gets slightly golden
- The cheese should be completely melted and starting to brown in spots
8. Rest and Serve
Letting the casserole rest makes it easier to serve and allows the flavors to settle.
- Remove the baking dish from the oven and let it sit for 5-10 minutes
- This resting time helps the casserole set up so it doesn’t fall apart when serving
- Use a large spoon or spatula to portion out servings
- The casserole should hold its shape reasonably well
- Garnish with fresh parsley or basil if desired
- Serve hot and enjoy

FAQs About Stuffed Pepper Casserole
1. Can I use uncooked rice in this casserole?
Yes, you can use uncooked rice, but you’ll need to adjust the cooking method.
Add an extra cup of beef broth and increase the covered baking time to 45-50 minutes to ensure the rice cooks through completely.
2. What’s the best type of rice to use?
Long-grain white rice works best because it stays fluffy and doesn’t get mushy.
You can also use brown rice, but it will require longer cooking time and more liquid.
3. Can I make this casserole ahead of time?
Absolutely! Prepare the entire casserole up to the baking step, cover tightly, and refrigerate for up to 24 hours. Add 10-15 minutes to the baking time if starting from cold.
4. How do I prevent my casserole from being watery?
Make sure to drain excess fat from the ground beef and don’t add more liquid than the recipe calls for.
Let the casserole rest for 10 minutes after baking so the rice can absorb any remaining liquid.
5. Can I freeze this casserole?
Yes, this casserole freezes beautifully. Freeze it before or after baking in an airtight, freezer-safe container for up to 3 months. Thaw in the refrigerator overnight before reheating.
