Ingredients

• 1.5 pounds sliced beef (such as flank steak or sirloin), thinly sliced against the grain
• 1 large green bell pepper, sliced into thin strips
• 1 large red bell pepper, sliced into thin strips
• 1 medium onion, thinly sliced
• Sauce Mixture:
  • 1/3 cup low-sodium soy sauce
  • 1/4 cup beef broth (halal certified or homemade for best flavor)
  • 2 tablespoons oyster sauce (choose vegetarian or halal-certified if preferred)
  • 1 tablespoon cornstarch (for thickening)
  • 2 tablespoons water (to dissolve cornstarch)
  • 2 teaspoons brown sugar or honey
  • 2 cloves garlic, minced
  • 1 teaspoon freshly grated ginger
  • 1/4 teaspoon black pepper

Step-by-Step Instructions

1. Prepare the sauce mixture: In a small bowl, whisk together the soy sauce, beef broth, oyster sauce, brown sugar or honey, minced garlic, grated ginger, and black pepper until well combined.
2. Dissolve the cornstarch: In a separate cup, mix cornstarch with 2 tablespoons of water until smooth. Set aside for later.
3. Layer ingredients in the crockpot: Start by adding the sliced beef to the bottom of the crockpot. Next, add the sliced green and red bell peppers and then the sliced onion on top.
4. Pour the sauce: Evenly pour the sauce mixture over the layered ingredients. Gently stir everything until the beef, peppers, and onions are well coated with the sauce.
5. Cook: Cover the crockpot and cook on LOW for 5 to 6 hours or on HIGH for 3 to 4 hours. If possible, stir once halfway through the cooking time to ensure even cooking and coating.
6. Thicken the sauce: About 30 minutes before serving, give the dissolved cornstarch a quick stir and pour it into the crockpot. Stir well to thicken the sauce. Taste and adjust seasoning with additional salt or pepper if necessary.
7. Serve: Serve the hot crockpot pepper steak over steamed rice or your favorite noodles for a fulfilling meal.

Pro Tips for Perfect Crockpot Pepper Steak

• Use good quality sliced beef: Flank steak or sirloin thinly sliced against the grain yields the best texture and tenderness after slow cooking.
• Don’t skip the half-time stir: This encourages even cooking and a better sauce coating.
• Cut vegetables evenly: Slice bell peppers and onions uniformly so they cook evenly and present beautifully.
• Adjust thickness preference: If you prefer a thinner sauce, reduce cornstarch or add a splash of beef broth when thickening.
• Fresh garlic and ginger: Using fresh ingredients rather than powders significantly boosts flavor and aroma.

Variations and Substitutions

• Protein swap: Substitute beef with halal chicken breast or thighs sliced thinly for a lighter version. Adjust cooking times accordingly.
• Vegetable add-ins: Include mushrooms, snap peas, or baby corn for added texture and nutrition.
• Healthier swaps: Use low-sodium soy sauce and reduce or replace sugar with natural sweeteners like stevia or monk fruit.
• Gluten-free option: Substitute soy sauce with tamari or coconut aminos to suit gluten-sensitive diets.
• Make it spicy: Add a dash of crushed red pepper flakes or a splash of sriracha before slow cooking for a delicious kick.

Storage and Reheating Tips

Store leftover Crockpot Pepper Steak in an airtight container in the refrigerator for up to 3-4 days. The flavors deepen upon sitting, making leftovers even better. To reheat, warm gently in a skillet over medium heat or microwave until heated through, stirring occasionally for even heating. If the sauce thickens excessively after refrigeration, add a splash of beef broth or water to loosen it before reheating.
