It’s a hearty, comforting dinner for busy weeknights and those days when you want a delicious homemade meal waiting for you.
🛒 Ingredients
For the Pepper Steak
- 1½–2 lbs beef, such as sirloin or flank steak, cut into strips
- ¼ cup soy sauce
- 1 teaspoon granulated sugar
- ¼ teaspoon ground ginger
- 1 clove garlic, minced
- 2 large bell peppers, chopped
- 1 large onion, sliced
- 1 can (14.5 oz) diced tomatoes, undrained
For Thickening
- 2 tablespoons cornstarch
- ¼ cup cold water
For Serving
- Fluffy cooked white rice
👩🍳 Instructions
1. Add the Beef to the Crockpot
Place the beef strips in the crockpot.
Add the soy sauce, sugar, ground ginger, and minced garlic. Stir gently to coat the beef.
2. Add the Vegetables
Add the chopped bell peppers and sliced onion.
Pour in the entire can of diced tomatoes, including the juice.
Give everything a good stir so the ingredients are evenly distributed.
3. Slow Cook
Cover the crockpot and cook until the beef is tender:
LOW: 6–8 hours
HIGH: 3–4 hours
Cooking times can vary depending on the size of the beef strips and your slow cooker.
4. Thicken the Sauce
About 30 minutes before serving, whisk the cornstarch and cold water together in a small bowl until completely smooth.
Stir the slurry into the crockpot.
5. Finish Cooking
Turn the slow cooker to HIGH if it isn’t already.
Cover and continue cooking for about 30 minutes, or until the sauce has thickened to your desired consistency.
6. Serve
Spoon the hot pepper steak and vegetables over fluffy white rice.
Serve immediately and enjoy this simple, hearty, and satisfying dinner!
⭐ Tips for Success
Cut the beef evenly: Similar-sized strips will cook more consistently.
Don’t skip the slurry: Mixing cornstarch with cold water first helps prevent lumps in the sauce.
Use colorful peppers: A combination of red, yellow, orange, and green bell peppers makes the dish especially colorful.
Adjust the sauce: If the sauce becomes thicker than you prefer, stir in a small splash of water or beef broth.
For easy cleanup: Use a crockpot liner or lightly grease the slow cooker before adding the ingredients.
🌶️ Easy Variations
For a little heat, add a pinch of red pepper flakes or a dash of hot sauce.
For extra flavor, add sliced mushrooms along with the peppers and onions.
You can also use a mixture of different colored bell peppers for a sweeter, more colorful dish.
