Ingredients

2 lbs. beef strips
1 green bell pepper, sliced thick
1 red bell pepper, sliced thick
1 white onion, sliced
½ cup water
2 beef bouillon cubes
3 Tbsp. soy sauce
1 tsp. Worcestershire sauce
¼ tsp. ground ginger
¼ tsp. garlic powder
½ tsp. black pepper
2 tsp. brown sugar (honey or white sugar work too)
1 Tbsp. cornstarch
¼ tsp. red pepper flakes (optional)

Instructions

Step 1: In a small microwavable bowl, add the water and beef bouillon cubes. Microwave for 30 seconds, then stir until the bouillon dissolves completely. (If you don’t have a microwave, heat the water on the stovetop until boiling and then stir in the cubes.)
Step 2: Add soy sauce, Worcestershire sauce, ground ginger, garlic powder, black pepper, brown sugar, and cornstarch to the bowl with the bouillon mixture. Whisk until smooth. If you want some heat, stir in the red pepper flakes as well. Pour this sauce into the slow cooker.
Step 3: Place the beef strips, sliced green and red bell peppers, and sliced onion on top of the sauce in the slow cooker. Make sure the ingredients are evenly distributed.
Step 4: Cover the slow cooker and cook on low for 5 hours, until the beef is tender and the vegetables are soft but still hold their shape.

Tips & Variations

For a thicker sauce, stir an additional 1 teaspoon of cornstarch mixed with cold water into the slow cooker about 30 minutes before serving.
Try adding mushrooms or snap peas for extra vegetables and texture.
If you prefer a sweeter flavor, swap brown sugar for honey or white sugar as suggested.
Serve over rice or egg noodles to soak up the delicious sauce.

Storage

Store leftover pepper steak in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat or in the microwave until warmed through. Avoid overcooking during reheating to keep the beef tender.

Serve this delicious recipe with your favorite sides.

FAQs

Can I use a different cut of beef for this recipe?

Yes, you can use sirloin, flank steak, or even stew meat. Just make sure to slice the beef into thin strips so it cooks evenly and becomes tender in the slow cooker.

Is it necessary to use beef bouillon cubes?

Beef bouillon cubes add rich flavor to the sauce, but if you don’t have them, you can substitute with beef broth or stock. Use ½ cup of broth in place of water and bouillon.
