Ingredients for the 15-Minute Pepper Steak Stir-Fry:

  • 8 oz (225g) flank steak, thinly sliced against the grain
  • 2 tablespoons olive oil, divided
  • 1 red bell pepper, cut into 1-inch cubes
  • 1 green bell pepper, cut into 1-inch cubes
  • 3 garlic cloves, minced
  • 1/4 cup brown sugar
  • 1/2 cup low sodium soy sauce
  • 2 teaspoons sesame oil
  • 1 teaspoon ground ginger
  • 1 tablespoon Sriracha (or your preferred hot sauce)
  • 1 tablespoon cornstarch

Instructions:

  1. Make the Sauce: In a small bowl, whisk together the minced garlic, brown sugar, soy sauce, sesame oil, ground ginger, Sriracha, and cornstarch until well combined. Set aside.
  2. Cook the Bell Peppers: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the diced red and green bell peppers and cook for 1-2 minutes until they become slightly tender. Remove from the pan and set aside on a plate.
  3. Cook the Steak: Increase the heat to high and add the remaining tablespoon of olive oil to the skillet. Arrange the sliced flank steak in a single layer, cooking each side to sear it. Once seared, reduce the heat to medium-high and cook for a few more minutes until the beef is browned and no longer pink.
  4. Combine and Simmer: Add the cooked bell peppers back to the skillet along with the prepared sauce. Stir everything together and let the sauce simmer for 1-2 minutes, until it thickens to your desired consistency.
  5. Garnish and Serve: Sprinkle the stir-fry with fresh chopped cilantro and sesame seeds for extra flavor and texture. Serve this pepper steak stir-fry over your favorite base, like steamed rice, rice noodles, or cauliflower rice.
