Nothing beats the aroma of tender beef and colorful bell peppers simmering away in your slow cooker after a long day.

This beloved dish traces its roots to traditional Chinese stir-fries but has evolved into an American comfort food staple that families have cherished for generations.

This crockpot pepper steak recipe delivers fork-tender strips of beef bathed in a savory-sweet sauce, paired with vibrant bell peppers and onions that maintain just the right amount of bite. What makes this dish truly special is how the slow cooking process allows all the flavors to meld together while the beef becomes incredibly tender – something that would take careful timing on the stovetop but happens effortlessly in your slow cooker.

Ingredients List

Main Components

2 pounds beef round steak or sirloin tip, cut into thin strips
3 large bell peppers (mix of red, green, and yellow), sliced into strips
1 large yellow onion, sliced into half-moons
3 cloves garlic, minced
1 can (14.5 oz) diced tomatoes, drained

Sauce Ingredients

1/3 cup soy sauce (low-sodium preferred)
2 tablespoons brown sugar
1 tablespoon cornstarch
1 teaspoon ground ginger
1/2 teaspoon black pepper
1/4 teaspoon red pepper flakes (optional)

For Serving

4-6 cups cooked white or brown rice
2 green onions, chopped (for garnish)
1 tablespoon sesame seeds (optional)

Substitution Notes: For gluten-free needs, use tamari instead of soy sauce. Coconut aminos work well for those avoiding soy entirely. If you can’t find round steak, chuck roast or even stew meat works beautifully in this slow-cooked preparation.

Timing

Prep Time: 15 minutes
Cook Time: 6-8 hours on low or 3-4 hours on high
Total Time: 6 hours 15 minutes to 8 hours 15 minutes

Time Management Tips: Start your rice about 20 minutes before the crockpot pepper steak finishes cooking. While the rice cooks, prepare your garnishes and set the table. This dish is perfect for meal prep – you can slice the vegetables and beef the night before, storing them separately in the refrigerator.

How to Make It

1. Prepare the Beef

Pat the beef strips completely dry with paper towels and season lightly with salt and pepper. For the most tender results, cut against the grain into strips about 1/4-inch thick. The drier the beef, the better it will brown and develop flavor during cooking.

2. Create the Sauce Base

In a small bowl, whisk together soy sauce, brown sugar, cornstarch, ground ginger, black pepper, and red pepper flakes until the cornstarch dissolves completely. This mixture will thicken beautifully during the slow cooking process, creating a glossy coating for the beef and vegetables.

3. Layer the Crockpot

Place the seasoned beef strips in the bottom of your slow cooker. Add the sliced bell peppers, onions, and minced garlic on top. Pour the drained diced tomatoes over the vegetables, then drizzle the sauce mixture evenly over everything.

4. Slow Cook to Perfection

Cover and cook on low for 6-8 hours or high for 3-4 hours. The beef should be fork-tender and the peppers should retain some texture but be easily pierced. Avoid lifting the lid during cooking, as this releases valuable heat and moisture.

5. Final Touches

During the last 30 minutes of cooking, give everything a gentle stir to distribute the thickened sauce. Taste and adjust seasoning if needed – you might want a touch more soy sauce or brown sugar depending on your preference.

Healthier Alternatives for the Recipe

Lower Sodium Version: Use low-sodium soy sauce and add extra garlic, ginger, and a splash of rice vinegar to boost flavor without increasing salt content.

Leaner Protein Options: Substitute the beef with boneless, skinless chicken thighs or lean pork tenderloin. Cooking times remain the same, but check for proper doneness.

Vegetable-Forward Variation: Add sliced mushrooms, snap peas, or broccoli florets during the last 2 hours of cooking for extra nutrients and fiber.

Reduced Sugar Alternative: Replace brown sugar with a small amount of honey or pure maple syrup, or omit sweetener entirely if you prefer a more savory profile.

Serving Suggestions

Serve this crockpot pepper steak over fluffy jasmine rice, nutty brown rice, or cauliflower rice for a lower-carb option. The sauce is perfect for drizzling over the rice, creating a complete and satisfying meal.

For special occasions, try serving over coconut rice or alongside steamed dumplings. A simple side of steamed broccoli or bok choy complements the flavors beautifully. Garnish with sliced green onions and a sprinkle of sesame seeds for restaurant-quality presentation.

Consider serving with crispy wonton strips on top for added texture, or alongside egg rolls for a complete Chinese-American feast that feels special but remains wonderfully approachable.

Common Mistakes to Avoid

Overcrowding the Crockpot: Don’t exceed your slow cooker’s capacity. The ingredients should fit comfortably with some room for steam circulation.

Skipping the Cornstarch: This ingredient is crucial for thickening the sauce. Without it, you’ll end up with thin, watery liquid instead of a glossy coating.

Adding Peppers Too Early: If you prefer firmer vegetables, add the bell peppers during the last 2-3 hours of cooking rather than at the beginning.

Using the Wrong Cut of Beef: Tender cuts like filet mignon will become mushy in the slow cooker. Tougher cuts like round steak become perfectly tender with long, slow cooking.

Storing Tips for the Recipe

Refrigerator Storage: Store leftovers in airtight containers for up to 4 days. The flavors often improve after a day in the refrigerator as they continue to meld together.

Freezer Storage: This dish freezes well for up to 3 months. Portion into family-sized containers before freezing for easy reheating.

Reheating Instructions: Reheat gently in the microwave or on the stovetop over medium-low heat. Add a splash of beef broth or water if the sauce seems too thick after storage.

Make-Ahead Tips: You can assemble all ingredients in the crockpot insert the night before and refrigerate. In the morning, simply place the insert in the slow cooker and start cooking.

FAQs

Can I use frozen beef in this crockpot pepper steak recipe?
It’s best to thaw the beef completely before cooking for food safety and even cooking. If you’re short on time, use the defrost setting on your microwave or place the sealed beef in cold water, changing the water every 30 minutes.

What’s the best cut of beef for slow cooker pepper steak?
Round steak, sirloin tip, or chuck roast work excellently because they become tender during long, slow cooking. Avoid expensive tender cuts as they’ll become mushy and waste money.

Can I make this recipe without tomatoes?
Absolutely! Simply omit the diced tomatoes and add an extra 1/4 cup of beef broth or water. The tomatoes add slight acidity and body to the sauce, but the dish is delicious without them.

How can I make the sauce thicker?
If your sauce seems thin, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir into the crockpot during the last 30 minutes of cooking. Let it cook uncovered to allow excess moisture to evaporate.

Can I double this recipe for a larger family?
Yes, but make sure your slow cooker can accommodate the increased volume. You may need to extend cooking time by 30-60 minutes when doubling the recipe to ensure everything cooks through properly.

What vegetables can I add to change things up?
Mushrooms, snap peas, carrots, and celery all work well. Add heartier vegetables like carrots at the beginning, and more delicate ones like snap peas during the last 1-2 hours of cooking.
