Step-by-Step Instructions
Follow these simple steps to ensure your pepper steak turns out perfectly every time.
- Prepare the Beef: Sprinkle beef sirloin strips with garlic powder. In a large skillet over medium heat, heat the vegetable oil. Sear the beef strips for about 5 minutes per side, until browned. Transfer the seared beef to your slow cooker.
- Create the Sauce: Dissolve the beef bouillon cube in hot water. Stir in cornstarch until fully dissolved to create a silky, lump-free mixture.
- Combine Ingredients: Pour the bouillon-cornstarch mixture over the beef in the slow cooker. Add the sliced onion, bell peppers, stewed tomatoes, soy sauce, sugar, and salt. Give everything a gentle stir to distribute ingredients evenly.
- Cook: Cover the slow cooker. Cook on High for 3 to 4 hours, or on Low for 6 to 8 hours, until the beef is fork-tender and the vegetables are soft but not mushy.
- Serve: Taste and adjust seasoning if needed. Serve hot, ideally over a bed of steamed rice or noodles.
Tips for Perfect Slow Cooker Pepper Steak
- Sear for Flavor: Though optional, searing the beef before slow cooking enhances flavor and texture.
- Don’t Overcrowd: Layer ingredients evenly to ensure even cooking.
- Vegetable Texture: For crisper peppers, add them during the last hour of cooking.
- Low and Slow: Cooking on low yields the most tender results.
- Thickening the Sauce: If you prefer a thicker sauce, increase the cornstarch or leave the lid off for the last 20 minutes of cooking.
Ingredient Substitutions & Variations
Ingredient | Substitution | Effect |
---|---|---|
Beef Sirloin/Top Round | Flank steak, stew meat, or chicken strips | Different textures; chicken cooks more quickly |
