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.
These are my go-to recommendations when friends ask what to buy.
1. Crock-Pot 6-Quart Programmable Slow Cooker
This programmable slow cooker has been my kitchen workhorse for years.
The automatic warm setting kicks in when cooking is done, so your pepper steak stays perfect even if you’re running late. The digital timer takes all the guesswork out of slow cooking.
2. Kikkoman Naturally Brewed Soy Sauce
Not all soy sauces are created equal, and this naturally brewed variety adds genuine depth of flavor without tasting artificial or overly salty.
It’s the same brand used in Japanese restaurants and makes a noticeable difference in the sauce.
3. Fresh Ginger Root
While ground ginger works in a pinch, fresh ginger brings a bright, zingy flavor that really elevates this dish. You’ll taste the difference in every bite, and it keeps for weeks in the fridge.
4. Wusthof Classic 8-Inch Chef’s Knife
Slicing beef thin is crucial for tender results, and this knife makes the job effortless. The sharp blade glides through meat and vegetables alike, cutting your prep time significantly.

Step-by-Step Instructions: How to Make Crockpot Pepper Steak
Follow these detailed steps to create perfect pepper steak in your slow cooker. The process is straightforward, but paying attention to a few key details ensures the best results.
1. Prepare the Beef
Getting the beef sliced properly is the most important step for tender results.
- Remove the beef from the refrigerator and let it sit at room temperature for 10 minutes (this makes slicing easier)
- Place the beef in the freezer for 15 minutes to firm it up slightly
- Using a sharp knife, slice the beef against the grain into thin strips, about 1/4-inch thick
- Trim off any excess fat or silver skin
- Season the beef strips lightly with salt and pepper
- Set aside while you prepare the vegetables
2. Slice the Vegetables
The vegetables should be cut into similar-sized pieces for even cooking.
- Wash and dry the bell peppers thoroughly
- Cut off the tops and bottoms, then remove the seeds and white ribs
- Slice the peppers into strips about 1/2-inch wide
- Peel and halve the onion, then slice into thin half-moons
- Mince the garlic cloves finely (or use a garlic press)
- Keep the peppers and onions separate from the beef for now
3. Mix the Sauce
Creating a flavorful sauce base is what makes this dish restaurant-quality.
- In a medium bowl, combine the beef broth and soy sauce
- Add the brown sugar and Worcestershire sauce
- Stir in the grated ginger and minced garlic
- Whisk everything together until the sugar dissolves completely
- Taste the sauce and adjust seasonings if needed (add more soy sauce for saltiness or brown sugar for sweetness)
- Set the sauce aside while you layer the crockpot
4. Layer the Crockpot
Proper layering ensures everything cooks evenly and the flavors meld together.
- Lightly spray or grease the inside of your slow cooker
- Add half of the sliced onions to the bottom of the crockpot
- Layer the beef strips on top of the onions
- Add the remaining onions over the beef
- Arrange the bell pepper strips on top of the onions
- Pour the drained diced tomatoes evenly over the peppers
- Pour the prepared sauce over all the ingredients
- Use a spoon to gently press everything down so it’s mostly submerged in liquid

5. Cook the Pepper Steak
Now comes the easy part where your slow cooker does all the work.
- Cover the crockpot with the lid
- Set to LOW for 6-8 hours or HIGH for 3-4 hours
- Resist the urge to lift the lid during cooking (this releases heat and extends cooking time)
- The pepper steak is done when the beef is fork-tender and easily pulls apart
- Check for doneness at the minimum time, then continue cooking if needed
6. Thicken the Sauce
Creating a glossy, restaurant-style sauce takes just a few extra minutes at the end.
- About 30 minutes before serving, check the consistency of the sauce
- In a small bowl, mix the cornstarch with 2 tablespoons of cold water to create a slurry
- Stir the slurry into the crockpot, mixing well to distribute evenly
- Re-cover and cook on HIGH for 20-30 minutes
- The sauce should thicken to a gravy-like consistency that coats the back of a spoon
- If it’s still too thin, make another small cornstarch slurry and repeat
7. Serve and Garnish
The final presentation makes this dish feel special.
- Prepare rice according to package directions (about 2 cups uncooked rice for 6 servings)
- Fluff the rice with a fork and divide among serving bowls or plates
- Use a slotted spoon to portion the pepper steak over the rice
- Spoon extra sauce from the crockpot over each serving
- Slice green onions thinly and sprinkle over the top
- Serve immediately while hot.
Tips for The Best Crockpot Pepper Steak
These tried-and-true tips come from making this recipe countless times and learning what works best.
Small adjustments can make a big difference in the final result.
- Slice beef when partially frozen: Pop the meat in the freezer for 15-20 minutes before slicing for cleaner, thinner cuts
- Cut against the grain: Look for the direction of the muscle fibers and slice perpendicular to them for maximum tenderness
- Don’t skip draining the tomatoes: Excess liquid from canned tomatoes can make the sauce too watery
- Use fresh ginger: Fresh grated ginger has more vibrant flavor than ground ginger and makes a noticeable difference
- Layer properly: Putting onions on the bottom protects the beef from direct heat and prevents drying out
- Add peppers with beef: Adding peppers at the beginning ensures they’re tender but not mushy
- Make cornstarch slurry: Always mix cornstarch with cold water first to prevent lumps in your sauce
- Let it rest: After thickening, let the pepper steak sit for 10 minutes for the sauce to fully set

Serving Suggestions

This pepper steak is delicious on its own, but pairing it with the right sides turns it into a complete meal.
The savory sauce works well with various accompaniments that soak up all those flavorful juices.
Here are my favorite ways to serve it:
- Over rice: White rice, brown rice, or jasmine rice are all perfect for soaking up the sauce
- With noodles: Lo mein noodles or rice noodles make this feel like authentic takeout
- Alongside vegetables: Steamed broccoli, Stir Fry Sauce vegetables, or bok choy add extra nutrition
- In lettuce wraps: Use crisp lettuce leaves as a low-carb alternative to rice
- Over mashed potatoes: The gravy-like sauce works surprisingly well with creamy mashed potatoes
- With cauliflower rice: A lighter option that still soaks up all the delicious sauce
- Topped on baked potatoes: Load up a split baked potato for a hearty comfort meal
Variations of Crockpot Pepper Steak
One of the best things about this recipe is how easily you can customize it to suit your tastes or use what you have on hand. Here are variations I make regularly.
- Spicy version: Add 1-2 teaspoons of red pepper flakes or a sliced jalapeño for heat
- Extra vegetables: Throw in mushrooms, snap peas, baby corn, or water chestnuts for more texture
- Pineapple twist: Add 1 cup of pineapple chunks during the last hour for sweet and savory flavor
- Low-sodium option: Use reduced-sodium soy sauce and beef broth to cut back on salt
- Gluten-free: Swap regular soy sauce for tamari or coconut aminos
- Different meats: Try chicken breast, pork tenderloin, or even turkey in place of beef
- Add heat: Stir in sriracha, chili garlic sauce, or hot sauce at the end

FAQs About Crockpot Pepper Steak
1. Can I use a different cut of beef?
Yes, you can use chuck roast, round steak, or stew meat instead of sirloin or flank steak.
Chuck roast will become especially tender with the long cooking time. Just make sure to trim excess fat and cut the meat into similar-sized strips for even cooking.
2. Why is my pepper steak tough?
If your beef is tough, it likely didn’t cook long enough or was sliced with the grain instead of against it.
The slow cooker needs adequate time to break down the connective tissue in the meat.
Make sure you’re cooking for at least 6 hours on LOW, and always slice against the grain.
3. Can I make this recipe in an Instant Pot?
Absolutely! Brown the beef using the sauté function, add all ingredients except cornstarch, and pressure cook on high for 25 minutes with natural release.
Then use the sauté function again to add the cornstarch slurry and thicken the sauce.
4. How do I prevent the peppers from getting mushy?
The peppers should stay relatively firm with the cooking times listed, but if you prefer them crunchier, add them during the last 2-3 hours of cooking instead of at the beginning.
They’ll still absorb flavor but maintain more texture.
5. Can I make this without cornstarch?
Yes, you can skip the cornstarch if you prefer a thinner sauce, or use an equal amount of arrowroot powder or tapioca starch as substitutes.
Alternatively, you can remove some of the liquid at the end and reduce it on the stovetop to thicken naturally.

- Cutting board
- Measuring cups and spoons

Method
- Let beef sit at room temperature for 10 minutes, then freeze for 15 minutes to firm up. Slice against the grain into thin strips about 1/4-inch thick, trim excess fat, and season lightly with salt and pepper.
- Remove seeds and ribs from bell peppers and slice into 1/2-inch strips. Peel and halve the onion, then slice into thin half-moons. Mince the garlic finely.
- In a bowl, whisk together beef broth, soy sauce, brown sugar, Worcestershire sauce, grated ginger, and minced garlic until the sugar dissolves completely. Taste and adjust seasoning as needed.
- Lightly grease the slow cooker insert, then layer in this order: half the onions on the bottom, beef strips, remaining onions, bell pepper strips, drained diced tomatoes, and finally the sauce poured evenly over everything.
- Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours without lifting the lid. The beef is done when it’s fork-tender and easily pulls apart.
- About 30 minutes before serving, mix cornstarch with 2 tablespoons cold water to make a slurry and stir it into the crockpot. Cook on HIGH for 20–30 minutes until the sauce reaches a gravy-like consistency.

Notes
- Slice beef against the grain: Find the direction of the muscle fibers and cut perpendicular to them for maximum tenderness.
- Partial freeze trick: Pop the beef in the freezer for 15–20 minutes before slicing for cleaner, thinner cuts.
- Drain the tomatoes: Skipping this step can make the sauce too watery and thin.
- Fresh ginger matters: Fresh grated ginger has a brighter, more vibrant flavor than ground — use it if you can.
- Don’t lift the lid: Every peek releases heat and adds 20–30 minutes to cooking time.
- Crunchier peppers: Add bell peppers during the last 2–3 hours of cooking instead of at the start for more texture.
- Alternate thickeners: Substitute arrowroot powder or tapioca starch 1:1 for cornstarch, or reduce liquid on the stovetop.
- Make it gluten-free: Use tamari or coconut aminos in place of soy sauce.
- Storage: Refrigerate in an airtight container for up to 4 days, or freeze in portions for up to 3 months. Add a splash of beef broth when reheating if the sauce has thickened.
- Instant Pot version: Brown beef on sauté, add all ingredients except cornstarch, pressure cook on HIGH for 25 minutes with natural release, then thicken with slurry on sauté.
