1 green bell pepper, sliced
1 red bell pepper, sliced
1 onion, sliced
3–4 cloves garlic, minced

Sauce

1 cup beef broth
1/4 cup soy sauce
2 tablespoons brown sugar
1 tablespoon cornstarch
1 teaspoon ground ginger (or fresh grated)
1/2 teaspoon black pepper

How to Make Slow Cooker Pepper Steak

Start by slicing the beef into thin strips, making sure to cut against the grain for tenderness. Slice the bell peppers and onion, and mince the garlic.

Place the beef, peppers, onion, and garlic directly into the slow cooker.

In a separate bowl, whisk together the beef broth, soy sauce, brown sugar, cornstarch, ginger, and black pepper until smooth and well combined.

Pour the sauce over the ingredients in the slow cooker, gently stirring to coat everything evenly.

Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the beef is tender and the sauce has thickened.

Give everything a good stir before serving to blend the flavors and distribute the sauce evenly.

Serve hot over steamed white rice, allowing the sauce to soak into the rice for maximum flavor.

Serving Suggestions

Serve over fluffy white rice or jasmine rice.
Pair with a side of steamed vegetables for a balanced meal.
Add sesame seeds or green onions on top for extra flavor and presentation.

Optional Add-Ins

Add broccoli or snap peas for more texture and nutrition.
Sprinkle in red pepper flakes if you like a bit of heat.
Finish with a splash of sesame oil for a richer, deeper flavor.

Tips for Best Results

Avoid lifting the lid while cooking to keep the heat consistent.
If the sauce needs extra thickening, let it cook uncovered for the last 15 minutes.
For even more flavor, sear the beef briefly before adding it to the slow cooker.
