For the Sauce:
- 1 cup beef broth

- 1 tablespoon rice vinegar
- 1 teaspoon sesame oil

For Serving:

How to Make Perfect Crockpot Pepper Steak
Step 1: Prepare the Beef
- Trim any excess fat from the beef and slice it into thin strips against the grain (this ensures tenderness).
- Season the beef strips with salt and pepper.
- Heat 1 tablespoon of oil in a large skillet over medium-high heat.
- Working in batches to avoid overcrowding, quickly sear the beef strips until just browned on the outside (about 1-2 minutes per side). They should not be fully cooked.
- Transfer the seared beef to your slow cooker.
Step 2: Prepare the Vegetables
- In the same skillet, add the remaining tablespoon of oil.
- Add the sliced onions and cook for 2-3 minutes until they begin to soften.
- Add the minced garlic and grated ginger, cooking for another 30 seconds until fragrant.
- Transfer the onion mixture to the slow cooker with the beef.
- Add the sliced bell peppers to the slow cooker (they’ll go in raw to prevent them from becoming too soft).
Step 3: Make the Sauce
- In a medium bowl, whisk together the beef broth, soy sauce, oyster sauce, brown sugar, rice vinegar, sesame oil, and black pepper.
- Pour this sauce mixture over the beef and vegetables in the slow cooker.
Step 4: Slow Cook to Perfection
- Cover the slow cooker and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, until the beef is tender.
Step 5: Thicken the Sauce
- About 30 minutes before serving, mix the cornstarch and cold water in a small bowl to create a slurry.
- Stir the slurry into the slow cooker, mixing well.
- Cover and continue cooking for 30 minutes until the sauce has thickened.
Step 6: Serve and Enjoy
- Serve the Crockpot Pepper Steak over hot cooked rice.
- Garnish with sliced green onions and a sprinkle of sesame seeds.
Pro Tips for Crockpot Pepper Steak Success
Beef Selection and Preparation
- Choose the right cut: While sirloin or round steak work beautifully, chuck roast can be an even more economical option
- Slice properly: Always cut against the grain for maximum tenderness
- Don’t skip the sear: This brief step adds tremendous depth of flavor to the final dish
- Freeze for easy slicing: Partially freezing the beef for 20-30 minutes makes it easier to slice thinly
Vegetable Variations
- Pepper alternatives: If bell peppers aren’t your favorite, try snow peas, sugar snap peas, or broccoli florets
- Add mushrooms: Sliced mushrooms make a wonderful addition, introducing an earthy flavor dimension
- Timing matters: If using more delicate vegetables, consider adding them during the last 1-2 hours of cooking
Serving Suggestions
- Beyond rice: Try serving over cauliflower rice, quinoa, or noodles for variety
- Garnish creatively: Fresh herbs like cilantro or Thai basil can brighten the dish
- Make it a feast: Pair with a simple cucumber salad or spring rolls for a complete Asian-inspired meal
