A set-it-and-forget-it favorite that delivers deep umami flavor with minimal effort.
-
Prep time: 15 minutes
-
Cook time: 4–6 hours (Low) or 2–3 hours (High)
-
Servings: 4–6
Ingredients
-
Beef: 1.5 lbs Sirloin tip, flank steak, or round steak (thinly sliced against the grain)
-
Vegetables: 2 large bell peppers (red and green), sliced; 1 medium onion, sliced.
-
Liquid Base: 1/2 cup beef broth (low sodium preferred).
-
The Sauce: 1/4 cup soy sauce, 1 tbsp Worcestershire sauce, 1 tbsp brown sugar, 1 tsp ground ginger, 2 cloves garlic (minced).
-
Thickener: 2 tbsp cornstarch mixed with 1/4 cup cold water (slurry).
Instructions
-
Layer: Place the sliced beef and onions into the slow cooker.
-
Whisk: In a small bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, ginger, and garlic.
-
Slow Cook: Pour the sauce over the beef. Cover and cook on Low for 5–6 hours or High for 2–3 hours until the beef is tender.
-
Add Peppers: About 30–45 minutes before serving, stir in the bell peppers. (This keeps them from getting mushy).
-
Thicken: Whisk the cornstarch and water to create a slurry. Pour it into the crock pot, stir, and cook on High for another 15 minutes until the sauce bubbles and thickens.
-
Serve: Spoon over hot white rice or rice noodles.
Tips for Success
-
Slicing Secret: Freeze your steak for 30 minutes before prep. It makes it much easier to get those paper-thin, restaurant-style slices.
-
The “Crunch” Factor: If you like your peppers crisp, add them only in the last 20 minutes. If you like them soft and integrated, add them at the start.
-
Searing (Optional): If you have time, sear the beef in a hot pan for 2 minutes before putting it in the crock pot. It adds a deeper “roasted” flavor.

Benefits of this Dish
-
High Protein: Excellent for muscle recovery and satiety.

Q&A
Q: Can I use frozen peppers?
A: Yes, but add them at the very end. Frozen peppers release more water, so you might need a slightly thicker cornstarch slurry.
Q: Is this gluten-free?
A: Not as written. To make it GF, swap the soy sauce for Tamari or coconut aminos and ensure your Worcestershire sauce is a certified GF brand.
Q: Can I make this in an Instant Pot?
A: Absolutely. Use the “Manual/Pressure Cook” setting for 10 minutes with a natural release, then use the “Sauté” function to thicken the sauce at the end.
