How to Make This Recipe
Step 1 – Prepare the Sauce
In a small bowl, whisk together the soy sauce, brown sugar, and corn starch until smooth. This sauce will add depth and sweetness to your stir fry. Once mixed, set it aside for later.
Step 2 – Sauté the Vegetables
Preheat your wok or large skillet over medium heat and add the oil. Once the oil is hot, add the sliced red and green bell peppers. Cook the peppers for about 3 minutes, or until they are soft and slightly golden. Remove the peppers from the pan and set them aside.
Step 3 – Cook the Beef
Increase the heat to high and add the beef strips to the pan. Sauté the meat for about 4–5 minutes, stirring occasionally, until it’s golden brown and cooked through. Add the pressed garlic and grated ginger to the beef, cooking for an additional minute until fragrant. Return the cooked peppers to the pan, then pour the prepared sauce over the beef and vegetables. Toss everything to coat evenly and cook for another 2–4 minutes to allow the sauce to thicken.
Remove from heat and serve your Pepper Steak Stir Fry alongside your favorite grain or noodle.
