Cooking Time & Prep Time

Ingredients

This recipe makes about 4–6 servings.

• 1½ pounds (700g) beef sirloin or flank steak, sliced into thin strips
• 2 tablespoons cornstarch
• 2 tablespoons olive oil
• 3 bell peppers (red, green, or yellow), sliced
• 1 medium onion, sliced
• 3 cloves garlic, minced
• 1 cup beef broth
• ¼ cup low-sodium soy sauce
• 1 tablespoon Worcestershire sauce
• 1 tablespoon brown sugar
• ½ teaspoon black pepper
• ½ teaspoon salt (adjust to taste)
• ½ teaspoon ground ginger (optional)
• 1 tablespoon water (for mixing with cornstarch if needed)

Optional garnish:

• Chopped green onions
• Sesame seeds

Step-by-Step Instructions

Step 1: Prepare the Beef

Slice the beef into thin strips. Try to cut against the grain. This helps keep the meat tender.

Place the beef in a bowl and sprinkle the cornstarch over it. Toss until all pieces are lightly coated.

Small tip: The cornstarch helps thicken the sauce later.

Step 2: Brown the Beef (Optional but Recommended)

Heat olive oil in a large pan over medium heat.
Add the beef strips and cook for 2–3 minutes until lightly browned.

You do not need to cook the beef fully at this stage. This step adds extra flavor but can be skipped if you are short on time.

Step 3: Prepare the Sauce

In a bowl, mix together:

• Beef broth
• Soy sauce
• Worcestershire sauce
• Brown sugar
• Black pepper
• Ginger (if using)

Stir well until combined.

Step 4: Add Ingredients to the Slow Cooker

Place sliced bell peppers and onions at the bottom of the slow cooker.
Add the browned beef on top.

Pour the sauce mixture over everything.
Add minced garlic last.

Cover with the lid.

Step 5: Cook Slowly

Cook on low for 6–8 hours or high for 3–4 hours.

The beef should become tender and easy to chew. The peppers will soften but still hold some shape.

Step 6: Thicken the Sauce (If Needed)

If the sauce looks too thin, mix 1 tablespoon cornstarch with 1 tablespoon water.
Stir this mixture into the slow cooker during the last 20–30 minutes of cooking.

Let it cook until the sauce thickens.

Step 7: Serve

Taste and adjust salt if needed.
Sprinkle with green onions or sesame seeds if desired.

Serve hot over rice or noodles.

Tips & Variations

For extra vegetables:
Add sliced mushrooms or carrots. They cook well in the slow cooker.

For a spicy version:
Add red pepper flakes or a spoon of chili sauce.

For a low-sodium option:
Use low-sodium soy sauce and reduce added salt.

For a gluten-free version:
Use gluten-free soy sauce or tamari. Make sure Worcestershire sauce is gluten-free.

For a low-carb meal:
Serve over cauliflower rice instead of regular rice.

For a vegetarian version:
Replace beef with firm tofu or sliced portobello mushrooms. Use vegetable broth instead of beef broth.

Small tip: If using tofu, add it in the last 2 hours so it does not break apart.
