Step 1: Prepare the Ingredients
- Slice the beef: Cut the sirloin steak (or flank steak) into thin strips against the grain.
- Prep the vegetables: Slice the onion and bell peppers. Mince the garlic.
Step 2: Sear the Beef (Optional but recommended)
- Heat the oil: In a large skillet, heat the olive oil over medium-high heat.
- Sear the beef: Add the beef strips to the skillet in batches, avoiding overcrowding. Cook for 2-3 minutes per side, or until browned. Remove the beef from the skillet and set aside. Searing adds extra flavor but can be skipped if you’re short on time.
Step 3: Assemble in the Crock Pot
- Layer the ingredients: Place the sliced onions and bell peppers in the bottom of the crock pot.
- Add the beef: Top the vegetables with the beef strips.
- Mix the sauce: In a bowl, combine the beef broth, soy sauce, oyster sauce (if using), brown sugar, and minced garlic. Pour the sauce over the beef and vegetables in the crock pot.
Step 4: Cook
- Cover and cook: Cover the crock pot with the lid and cook on low for 6-7 hours or on high for 3-4 hours, until the beef is tender and the vegetables are cooked.
Step 5: Thicken the Sauce
- Prepare the cornstarch slurry: In a small bowl, mix the cornstarch with water to form a slurry.
- Add to the crock pot: About 30 minutes before serving, stir the cornstarch slurry into the crock pot to thicken the sauce. If you’re using the high setting, you may need to cook for an additional 20-30 minutes for the sauce to thicken.
Step 6: Serve
- Season: Taste and adjust seasoning with salt and black pepper if needed.
- Serve: Serve the pepper steak over cooked rice or noodles. Garnish with additional sliced green onions or sesame seeds if desired.
Tips and Tricks
- For extra flavor: Add a splash of rice vinegar or a sprinkle of red pepper flakes for a bit of tang and heat.
- Vegetable variations: You can add other vegetables like snap peas or mushrooms if you like.
- Make-ahead: This dish can be prepared ahead of time and stored in the refrigerator for up to 3 days. It also freezes well for up to 3 months.
