Ingredients
Scale
Meat
- 680 grams flank steak or sirloin, thinly sliced into strips
Vegetables and Aromatics
- 3 bell peppers (red, green, yellow), sliced
- 1 medium onion, sliced
- 3 cloves garlic, minced
Liquids and Sauces
- 60 milliliters soy sauce
- 60 milliliters beef broth
- 30 milliliters Worcestershire sauce
- 30 milliliters olive oil
Thickener
- 8 grams cornstarch
- 15 milliliters water
Spices
- 1 teaspoon black pepper
- 1/2 teaspoon crushed red pepper flakes (optional)
Instructions
- Sear the steak: Heat olive oil in a large skillet over medium-high heat. Add the sliced flank steak and sear for 2 to 3 minutes until browned on the outside but not fully cooked through. This step locks in flavor and improves the texture.
- Combine in slow cooker: Transfer the seared steak strips to the slow cooker. Add sliced bell peppers, onion, minced garlic, soy sauce, beef broth, Worcestershire sauce, black pepper, and crushed red pepper flakes. Gently stir to combine all ingredients evenly.
- Slow cook the mixture: Cover the slow cooker and cook the mixture on low for 6 to 8 hours, or on high for 3 to 4 hours. This slow cooking process tenderizes the steak and allows the flavors to meld beautifully with the vegetables.
- Thicken the sauce: About 30 minutes before serving, whisk together cornstarch and water until smooth. Stir this slurry into the slow cooker and cook uncovered to thicken the sauce. This will create a glossy and rich coating for the steak and peppers.
- Serve: Once the sauce has thickened, serve the pepper steak hot over steamed rice or noodles to soak up the delicious juices and complete the meal.
Notes
- For thicker sauce, adjust cornstarch amount accordingly or allow extra time to reduce the sauce uncovered.
- You can substitute flank steak with sirloin or skirt steak for similar results.
- Adding crushed red pepper flakes is optional but adds a nice kick of heat.
- Serve with steamed rice or egg noodles for a satisfying dinner.
- Leftovers can be refrigerated for up to 3 days and reheated gently before serving.
