Ingredients
- 1 1/2 pounds Beef sirloin
- 1 large Red bell pepper
- 1 large Green bell pepper
- 1 medium Yellow onion
- 3 cloves Garlic
- 1 cup Beef broth
- 1/3 cup Low sodium soy sauce
- 1 tablespoon Worcestershire sauce
- 1 tablespoon Brown sugar
- 1 teaspoon Ground ginger
- 1/2 teaspoon Black pepper
- 3 tablespoons divided Cornstarch
- 2 tablespoons Cold water
- 2 tablespoons Sliced green onions
Instructions
- Cut the 1 1/2 pounds of beef into thin irregular strips that vary slightly in length. Slice the red pepper and green pepper into loose uneven strips then cut the onion into casual wedges. The food changes from whole ingredients into bite sized pieces with natural spacing and slight overlap. Keep the beef separate from the vegetables at this stage.
- Transfer the sliced beef into a mixing bowl then scatter two tablespoons of cornstarch with the ground ginger and black pepper over the strips. Fold everything until the beef looks lightly dusty and unevenly coated. The beef changes from glossy red strips to a pale matte surface with a few visible patches of seasoning. The strips shift toward the center and overlap loosely after mixing.
- Place the coated beef strips across the bottom of the slow cooker crock then scatter the red pepper and green pepper strips with onion wedges over and between the beef. Pour the broth mixture with soy sauce and Worcestershire sauce plus brown sugar and garlic across the layers. The dry coated beef becomes wet and glossy while the vegetables remain partly exposed. The ingredients shift from separate groups into an uneven layered mixture with sauce collecting around the edges.
- Cook the layered mixture until the beef changes from red to deep brown and the pepper strips soften while still showing their colors. The onion wedges become translucent and the sauce begins to darken. The beef strips settle lower in the crock and shift into loose folds while the vegetables spread through the liquid. A few exposed beef edges show natural browning and the sauce remains slightly thin.
- Stir one tablespoon of cornstarch with two tablespoons of cold water then fold the slurry into the hot pepper steak. Continue cooking until the sauce changes from thin and loose to glossy and thick enough to cling to the beef. The beef and vegetables shift from the edges toward the center as the mixture is stirred. The peppers overlap in new positions and the sauce coats them unevenly with a homemade finish.
- Scoop one generous portion onto a white plate with several tender beef strips plus red and green pepper pieces and onion coated in the thick sauce. Scatter the sliced green onions unevenly over the top. The food transfers from the crock into a close serving arrangement that reveals glossy sauce and tender interiors. Keep the portion casual with irregular overlaps and visible browned beef edges.
Notes
Pro Tips:
- Slice the beef against the grain and keep the strips slightly uneven so they cook tender while still looking naturally homemade.
- Add the bell peppers in thick strips because thin pieces can soften too quickly and disappear into the sauce during long cooking.
- Use low sodium soy sauce so the savory flavor stays balanced after the liquid reduces and the sauce becomes more concentrated.
- Stir in the cornstarch slurry only near the end because early thickening can make the sauce cloudy and overly heavy.
Storage: Cool the Slow Cooker Pepper Steak before storing it so trapped steam does not create extra water in the sauce. Transfer portions into airtight containers within two hours of cooking. Refrigerate the pepper steak for up to four days. Keep each portion covered so the beef stays moist and the peppers do not absorb other refrigerator odors. Freeze cooled portions for up to three months in freezer safe containers. Leave a little room at the top because the sauce expands as it freezes. Thaw frozen portions overnight in the refrigerator then reheat gently until steaming hot. Add a small splash of broth if the sauce becomes too thick during reheating.
