Ingredients
- 1 pound beef sirloin, sliced into thin strips
- 1 large white onion, sliced
- 3 cloves garlic, minced
- 1 teaspoon ground ginger
- 2 cups beef broth
- 1/4 cup soy sauce
- 2 tablespoons brown sugar
- 2 tablespoons cornstarch
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- Steamed white rice, for serving
Step-by-Step Instructions
- Prepare the slow cooker: Place the sliced beef sirloin, sliced onion, minced garlic, and ground ginger into your slow cooker.
- Mix the sauce: In a medium bowl, combine the beef broth, soy sauce, and brown sugar. Stir well until the sugar dissolves completely.
- Add the sauce: Pour the broth mixture over the beef and onions in the slow cooker, ensuring all ingredients are evenly coated.
- Cook low and slow: Cover and cook on low for 5 hours. This slow cooking will tenderize the beef and deepen the flavors.
- Thicken the sauce: After 5 hours, carefully scoop out about a cup of the cooking liquid into a separate bowl. Whisk in the cornstarch until smooth, then stir this mixture back into the slow cooker.
- Add the peppers: Gently fold in the sliced green and red bell peppers. Switch the slow cooker to high and cook for an additional 45 minutes, allowing the sauce to thicken and the peppers to soften.
- Serve: Spoon the pepper steak over freshly steamed white rice and enjoy your deliciously tender, flavorful meal.
Pro Tips for Perfect Slow Cooker Pepper Steak
- Slice beef thinly: Cutting the sirloin into thin strips rather than chunks ensures even cooking and tenderness.
- Use low-sodium soy sauce: This controls saltiness and lets you adjust seasoning to taste.
- Don’t skip the cornstarch step: Thickening the sauce after cooking keeps it glossy and clingy to the beef and peppers.
- Peppers added late: Adding bell peppers only during the final 45 minutes preserves their crunch and prevents them from becoming mushy.
- Let it rest: After cooking, allowing the dish to sit for 5-10 minutes helps flavors meld beautifully.
Variations and Substitutions
Feel free to customize this versatile pepper steak recipe according to your preferences or dietary needs:
- Meat alternatives: Try substituting sirloin with lean flank steak or eye of round for a slightly different texture.
- Vegetable variations: Add sliced mushrooms, snap peas, or baby corn along with the peppers for extra crunch and nutrition.
- Healthier swaps: Use low-sodium beef broth and reduce or omit the brown sugar to decrease sodium and sugar content.
- Gluten-free version: Substitute soy sauce with tamari or coconut aminos for a gluten-free-friendly option.
- Rice alternatives: Serve over cauliflower rice or quinoa for a low-carb or higher-protein meal.
Storage and Reheating Tips
Store leftover Slow Cooker Pepper Steak in an airtight container in the refrigerator for up to 3 days. When reheating, warm it gently in a saucepan over medium heat, stirring occasionally to prevent sticking and to evenly heat the dish. If the sauce thickens too much, add a splash of beef broth or water to loosen it. This dish can also be frozen in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator and reheat thoroughly before serving.
