Ingredients
Scale
Beef and Seasoning
- 1 1/2 pounds beef sirloin or flank steak, thinly sliced into strips
- 2 tablespoons cornstarch
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons olive oil (for searing, optional)
Vegetables
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 1 small onion, sliced
- 3 cloves garlic, minced
Sauce
- 1/3 cup low-sodium soy sauce
- 1/3 cup beef broth
- 2 tablespoons brown sugar
- 1 tablespoon rice vinegar (or white vinegar)
- 1 tablespoon tomato paste
- 1 teaspoon ground ginger
Instructions
- Prepare the beef: In a bowl, toss the thinly sliced steak with cornstarch, salt, and black pepper until the meat is evenly coated. This helps thicken the sauce later and seasons the beef.
- Sear the beef (optional): Heat olive oil in a skillet over medium-high heat. Quickly sear the beef strips for 2 to 3 minutes on each side. This step enhances flavor but can be skipped for convenience.
- Add ingredients to slow cooker: Transfer the beef strips to the slow cooker. Layer the sliced green and red bell peppers, onion, and minced garlic over the beef.
- Make and add the sauce: In a small bowl, whisk together soy sauce, beef broth, brown sugar, rice vinegar, tomato paste, and ground ginger. Pour this mixture evenly over the beef and vegetables in the slow cooker.
- Cook: Cover the slow cooker and cook on low for 6 to 7 hours or on high for 3 to 4 hours. Cooking until the beef is tender and the peppers are soft but still hold their shape.
- Optional sauce thickening: For a thicker sauce, about 30 minutes before the end of cooking, mix 1 tablespoon cornstarch with 1 tablespoon cold water and stir into the slow cooker.
- Serve: Stir everything just before serving and enjoy hot over rice, noodles, or cauliflower rice for a complete meal.
Notes
- Thickening the sauce at the end with a cornstarch slurry enhances texture.
- Leftovers reheat well, making this recipe ideal for meal prep.
- Searing the meat before slow cooking adds deeper flavor but can be skipped for a faster prep.
