* 1 lb flank steak or sirloin, thinly sliced against the grain
* 2 tablespoons soy sauce (low sodium preferred), plus 1 tablespoon for sauce
* 1 tablespoon cornstarch, plus 1 teaspoon for sauce
* 1 teaspoon sesame oil, plus 1/2 teaspoon for sauce
* 1/2 teaspoon black pepper
* 2 tablespoons vegetable oil, divided
* 1 large bell pepper (any color), thinly sliced
* 1 medium bell pepper (contrasting color), thinly sliced
* 1/2 medium yellow onion, thinly sliced
* 3 cloves garlic, minced
* 1 tablespoon fresh ginger, grated
* For the Sauce: * 1/2 cup beef broth * 1 tablespoon soy sauce * 1 teaspoon cornstarch * 1 teaspoon honey or brown sugar * 1/2 teaspoon sesame oil * Pinch of red pepper flakes (optional)

Serve with steamed white or brown rice, or your favorite noodles.

Step-by-Step Instructions

Creating this stir fry is a breeze when you follow these simple steps:

1. Marinate the Beef: In a medium bowl, combine thinly sliced beef with 2 tablespoons soy sauce, 1 tablespoon cornstarch, 1 teaspoon sesame oil, and black pepper. Toss to coat evenly. Let it sit for at least 10 minutes while you prep vegetables.
2. Prep Vegetables & Sauce: Slice bell peppers and onion. Mince garlic and grate ginger. In a small bowl, whisk together all sauce ingredients: beef broth, 1 tablespoon soy sauce, 1 teaspoon cornstarch, honey or brown sugar, 1/2 teaspoon sesame oil, and optional red pepper flakes. Set aside.
3. Cook the Beef: Heat 1 tablespoon vegetable oil in a large skillet or wok over high heat. Add half of the marinated beef in a single layer. Cook for 2-3 minutes, stirring, until browned. Remove to a clean plate. Add remaining 1 tablespoon oil and cook rest of beef. Remove and set aside.
4. Sauté Aromatics & Vegetables: Reduce heat to medium-high. Add sliced onions to skillet and stir-fry 2-3 minutes until softened. Add minced garlic and grated ginger, cooking for another minute until fragrant. Add sliced bell peppers and stir-fry 3-5 minutes until crisp-tender.
5. Combine & Sauce: Return cooked beef to the skillet. Give whisked sauce a quick stir and pour over beef and vegetables. Bring to a simmer, stirring, until sauce thickens and coats everything, about 1-2 minutes.
6. Serve: Remove from heat immediately. Serve hot over steamed rice or noodles, garnished as desired.

Expert Tips

Achieving stir-fry perfection means paying attention to a few key details. Always slice beef against the grain into thin, uniform strips for tenderness. A great stir fry demands high heat; your skillet should be piping hot to create a browned exterior and prevent steaming. Avoid overcrowding the pan when cooking beef; work in batches if necessary, allowing ingredients to sear rather than steam. Lastly, have all ingredients prepped and within reach before you start – ‘mise en place’ is crucial for fast-paced stir-frying.

Variations

The beauty of a stir fry lies in its adaptability. Don’t be afraid to make this recipe your own! Swap the beef for boneless chicken, shrimp, or firm tofu, adjusting cooking times. Boost your veggie intake by adding quick-cooking options like broccoli florets, snap peas, sliced carrots, or mushrooms with the bell peppers. Experiment with your sauce; a touch of hoisin adds sweet depth, while oyster sauce offers richer umami. For a spicy kick, increase red pepper flakes or add chili garlic sauce. Finish with toasted sesame seeds or fresh chopped green onions for extra flavor.

Conclusion

And there you have it: a truly delicious and surprisingly simple Easy Skillet Beef & Pepper Stir Fry, ready to rescue your weeknights. This dish proves that healthy, flavorful meals don’t require hours in the kitchen. With its vibrant colors, tender textures, and rich, savory sauce, it’s a meal that satisfies.
