Ingredients

  • 2 lbs beef sirloin or flank steak, thinly sliced

  • 2 tablespoons olive oil

  • 1 medium green bell pepper, sliced

  • 1 medium red bell pepper, sliced

  • 1 medium yellow bell pepper, sliced

  • 1 medium onion, sliced

  • 3 cloves garlic, minced

  • 1 cup beef broth

  • ½ cup low-sodium soy sauce

  • ¼ cup brown sugar

  • 2 tablespoons Worcestershire sauce

  • 1 tablespoon tomato paste

  • 1 teaspoon freshly grated ginger

  • ½ teaspoon black pepper

  • ½ teaspoon paprika

  • 2 tablespoons cornstarch

  • 3 tablespoons cold water

  • 1 teaspoon sesame oil (optional)

  • 2 tablespoons chopped green onions, for garnish

  • 1 teaspoon sesame seeds, optional

Instructions

1. Prepare the beef.
Trim away any excess fat from the beef and slice it into thin strips against the grain. Cutting against the grain helps make the cooked beef more tender.

2. Prepare the vegetables.
Wash the bell peppers, remove the seeds, and slice them into strips. Slice the onion and mince the garlic.

3. Optional: Brown the beef.
Heat olive oil in a large skillet over medium-high heat. Working in batches, quickly brown the beef strips for 1–2 minutes. This step adds extra flavor but is not essential.

4. Make the sauce.
In a mixing bowl, whisk together the beef broth, soy sauce, brown sugar, Worcestershire sauce, tomato paste, minced garlic, grated ginger, black pepper, and paprika until combined.

5. Assemble the crockpot.
Place the sliced beef in the bottom of the slow cooker. Add the sliced onion and pour the prepared sauce over the beef. Stir gently to coat everything.

6. Slow cook the steak.
Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours, until the beef is tender. Cooking time may vary depending on the cut and thickness of the beef strips.

7. Add the bell peppers.
Add the sliced green, red, and yellow bell peppers during the final 45–60 minutes of cooking. This helps them become tender while retaining some texture and color.

8. Thicken the sauce.
In a small bowl, whisk together the cornstarch and cold water until smooth. Stir the mixture into the crockpot during the final 20–30 minutes of cooking. Cover and allow the sauce to thicken.

9. Add finishing flavor.
Stir in the optional sesame oil. Taste the sauce and adjust the seasoning if needed.

10. Garnish and serve.
Sprinkle with chopped green onions and sesame seeds. Serve hot over rice, noodles, or mashed potatoes.

Recipe Notes

  • Best beef cuts: Sirloin, flank steak, or round steak work well. Slice the beef thinly against the grain.

  • Tender beef: Avoid cooking the beef longer than necessary once it becomes tender.

  • Crisp-tender peppers: Add bell peppers toward the end rather than at the beginning.

  • Soy sauce: Use low-sodium soy sauce to control the saltiness.

  • Thicker gravy: Add the cornstarch slurry gradually until the sauce reaches your preferred consistency.

  • Gluten-free option: Use certified gluten-free tamari and gluten-free Worcestershire sauce.

  • Sweetness: Adjust the brown sugar to your taste or use a smaller amount.

Helpful Tips

  1. Slice the beef into evenly sized strips so it cooks consistently.

  2. Brown the beef in batches if you want deeper, richer flavor.

  3. Do not overcrowd the slow cooker.

  4. Keep the lid closed during cooking to maintain a steady temperature.

  5. Add peppers near the end to prevent them from becoming mushy.

  6. Always mix cornstarch with cold water before adding it to the hot sauce.

  7. Let the finished pepper steak rest for about 5 minutes before serving.
