Pepper Steak Stir Fry

Nothing combines tender, juicy flat iron steak with vibrant, spicy peppers quite like stir fry. My Pepper Steak Stir Fry recipe is a symphony of flavors and textures that will have your family raving. It’s the perfect blend of savory beef seasoning, aromatic garlic and ginger, and the subtle heat of red pepper flakes, all wrapped up in a rich sauce.

All you need is a good wok or deep pan, and, of course, the will to resist the tempting aroma filling the air as you cook. If you’ve got what it takes, then you’ll turn out amazing pepper steak your friends and family will love. Let’s get going.

The Best Beef for Stir Fry

For stir fry beef, you want to go with a thin cut that will cook quickly while remaining tender. While pepper steak is traditionally made with flank steak, I’m making this recipe with flat iron steak. It’s a little bit more per pound, but the tenderness is worth it in my opinion. I absolutely love the melt-in-your-mouth tenderness and rich, beefy flavor of this cut.

Tenderizing Your Beef

To get the most tender flat iron steak possible, I highly recommend tenderizing your beef. Place the steak between two pieces of plastic wrap and use a meat mallet or heavy bottom skillet to gently pound the steak to an even thickness. This process helps to break down the tough fibers in the meat, resulting in a more tender and enjoyable eating experience.

Stir Fry Pepper Sauce

The sauce is the heart and soul of this Pepper Steak Stir Fry, perfectly balancing the savory beef and heart peppers. The beef stock, sweet mirin, and salty soy sauce creates a rich, umami base, while the dark brown sugar adds a touch of sweetness. The red pepper flakes provide a subtle kick of heat that complements the savory flavors, but isn’t overpowering. Here’s what you’ll need:

  • 4 Tablespoons cool water
  • 2 Tablespoons cornstarch
  • 1/2 cup mirin
  • 1/2 cup beef stock
  • 1/4 cup soy sauce
  • 2 Tablespoons dark brown sugar
  • 1 teaspoon red pepper flakes
  • 1/2 teaspoon black pepper

Feel free to adjust the amount of red pepper flakes to suit your taste preferences. If you enjoy a spicier stir fry, you can increase the amount to 1 or 1 1/2 teaspoons. If you prefer a milder flavor, then you can reduce the red pepper flakes to 1/2 teaspoon or omit them entirely. The beauty of this recipe is that it’s easily customizable to your liking.

How to Make Pepper Steak

You’ll be shocked how simple it is to make this Asian-inspired pepper steak. Once you’ve gathered your ingredients, just follow these easy steps:

  1. Prep beef. Start by tenderizing your steak with a meat mallet, and then slicing into thin strips. Remember, if you’re using a tougher cut like flat iron steak, be sure to slice against the grain.
  2. Prep the sauce. Combine your water and cornstarch in a small bowl, and the remainder of your sauce ingredients in a separate mixing bowl, and set both aside.
  3. Cook beef. In a large skillet or wok, heat your oil over medium-high heat. You want to give your steak for 2-3 minutes, or until browned. Then, set aside on a plate.
  4. Stir fry vegetables. In the same pan, add a bit more oil if needed, then toss in your sliced bell peppers and onion. Stir-fry until the veggies are tender, and slightly charred around the edges. Add the minced garlic and cook for another minute or so, until fragrant.
  5. Add sauce. Pour the sauce mixture into the wok, scraping the bottom and sides to remove all of the flavorful browned on bits into the sauce. You want to allow your sauce to simmer 4-5 minutes until it reduces by about half, then mix in your cornstarch slurry.
  6. Combine, serve, and enjoy. Let the sauce simmer for a minute or two, until it thickens up nicely. Then add the steak back into the pan and toss everything together until the steak is heated through and coated in that delicious sauce. Serve your pepper steak hot, over a bed of steamed rice or noodles. Garnish with some sliced green onions or sesame seeds for a pop of freshness and crunch.

Serving Suggestions

This spicy pepper steak dish is traditionally served freshly mixed right out of the wok on a bed of noodles or rice. I’m a sucker for rice with beef, so I prepared a simple white rice to go along with by steak. You can go with brown rice if that’s more your style, or your favorite noodle. As you get more confident playing with the recipe, you’ll likely find different combos you love.
