The magic of this Pepper Steak Stir Fry Recipe comes from simple, easy-to-find ingredients that each play a crucial role: the cornstarch for perfect texture, fresh vegetables for crunch, and a sauce that brings the whole dish together with a savory-sweet kick.

Cornstarch (4 Tbsp divided use): Helps tenderize the steak and thickens the sauce for that perfect glaze.
Top round or flank steak (1 1/2-2 lbs): Thinly sliced for fast, even cooking and tender bites.
Salt (1 tsp divided use): Enhances the natural flavors of the steak and vegetables.
Black pepper (1 tsp divided use): Adds a mild heat that complements the bell peppers perfectly.
Vegetable oil (3 Tbsp): A neutral oil for searing the steak and sautéing veggies without overpowering flavors.
Sesame oil (1 tsp): Just a touch for that unmistakable nutty aroma.
Red bell pepper (1 large, sliced): Sweet and colorful, it’s a star ingredient in this stir fry.
Green bell pepper (1 large, sliced): Adds a nice contrast in color and a slightly deeper flavor.
White onion (1 medium, thinly sliced): Provides sweetness and a bit of bite when cooked.
Garlic cloves (3 large, minced): Fresh garlic brings unmistakable warmth and aroma.
Minced ginger (1 tsp): Adds a subtle zing that lifts the dish.
Soy sauce or teriyaki sauce (2/3 cup): The salty, umami base of the stir fry sauce.
Beef stock or water (2/3 cup): Adds depth and moisture to the sauce.
Light brown sugar (3 Tbsp): Balances the saltiness with a touch of caramel sweetness.
Rice wine vinegar (2 Tbsp): A bit of tang to brighten the overall flavor.

How to Make Pepper Steak Stir Fry Recipe

Step 1: Prepare and Season the Steak

Start by sprinkling the steak strips with 1 tablespoon of cornstarch, half a teaspoon of salt, and half a teaspoon of black pepper. Toss everything together so each piece is lightly coated – this step not only seasons the meat but gives it a wonderful texture once cooked.

Step 2: Sauté the Vegetables

Heat 1 tablespoon of vegetable oil in a large 12-inch skillet over medium-high heat. Add the sliced red and green bell peppers along with the onions. Season with the remaining salt and pepper. Cook for 3 to 4 minutes, just until they’re tender-crisp and starting to brown – you want to retain that fresh crunch for contrast with the steak.

Step 3: Add Garlic and Ginger

Stir in the minced garlic and ginger, cooking for an extra minute until fragrant but not browned. This step infuses the vegetables with those warm aromatic flavors that define a great stir fry. Remove the vegetables from the skillet and set them aside on a platter to keep warm.

Step 4: Cook the Steak

Into the same skillet, add the remaining 2 tablespoons of vegetable oil plus the sesame oil. Arrange the steak strips in a single layer and cook over medium-high heat in batches for about 1 to 2 minutes per side. The quick, hot sear locks in juices and keeps the steak tender. Use a slotted spoon to transfer the cooked steak to the platter with the veggies.

Step 5: Prepare the Sauce

In a small bowl, whisk together the remaining 3 tablespoons of cornstarch with the soy or teriyaki sauce, beef stock, brown sugar, rice wine vinegar, and crushed red pepper flakes. This sauce strikes the perfect balance of savory, sweet, tangy, and spicy that ties the entire dish together.

Step 6: Combine and Simmer

Return the bell peppers and onions to the skillet along with the cooked steak. Pour the sauce mixture over everything and bring to a simmer over medium-high heat. Stir constantly for 2 to 3 minutes until the sauce thickens and thoroughly coats all the ingredients. This glossy finish is what makes the Pepper Steak Stir Fry Recipe so irresistible.

Step 7: Serve Immediately

This dish is best enjoyed right away, served piping hot over fluffy white rice or your favorite grain. Don’t forget to sprinkle with sesame seeds and sliced green onions for that final layer of flavor and crunch.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftovers to an airtight container and store in the refrigerator for up to 3 days. The flavors meld even more after sitting, making it delicious the next day.

Freezing

This Pepper Steak Stir Fry Recipe freezes well. Place portions in freezer-safe containers or bags and freeze for up to 2 months. Just be sure to thaw overnight in the fridge before reheating to preserve texture.

Reheating

Reheat the stir fry gently on the stovetop over medium heat, stirring occasionally until warmed through. You can add a splash of water or beef stock if the sauce thickens too much. Avoid the microwave if possible to keep the vegetables crisp and steak tender.

FAQs

Can I use a different cut of beef?

Absolutely! While top round and flank steak are recommended because they’re lean and cook quickly, you can also use sirloin or skirt steak. Just be sure to slice thinly against the grain for the most tender results.

Is this recipe spicy?

This Pepper Steak Stir Fry Recipe has a mild kick from the crushed red pepper flakes, but it’s easy to adjust. Add more flakes or serve with chili sauce on the side if you love heat, or leave them out for a milder flavor.

Can I make this dish vegetarian?

You can swap the steak for firm tofu or seitan and keep all the other ingredients the same. The flavorful sauce makes it delicious regardless of the protein choice.

What can I use instead of beef stock?

If you don’t have beef stock, water works just fine. For extra flavor, consider using vegetable stock or even a splash of mushroom broth to keep it savory.

How long does this dish take to prepare?

From start to finish, this Pepper Steak Stir Fry Recipe takes about 30 minutes, making it a fantastic option for a quick and satisfying weeknight dinner.
