How to Make Pepper Steak with Bell Peppers and Onion

Whisk Together: In a bowl, combine soy sauce, minced garlic, ginger, and brown sugar. This flavorful marinade will infuse your flank steak with layers of savory goodness.
Marinate the Steak: Thinly slice the flank steak and let it soak in the marinade for 15 minutes to 2 hours. The longer, the better for tender, flavor-rich beef.
Heat the Skillet: In a skillet or wok, heat oil over medium-high heat. Cook the marinated steak in batches for 1-2 minutes until each piece is nicely browned. This creates a perfect sear!
Set the Steak Aside: Once browned, remove the steak and set it aside. If needed, add a touch more oil to the skillet for the vegetables.
Stir-Fry the Vegetables: Toss in the bell peppers and onions. Stir-fry for 3-5 minutes until they’re tender-crisp, vibrant, and slightly caramelized.
Thicken the Sauce: Mix cornstarch with a bit of water to create a slurry. Add this to the skillet along with the remaining marinade, simmering until the sauce thickens to a glossy finish.
Combine and Serve: Return the steak to the skillet, tossing everything together until the meat is well-coated with the sauce. Serve this delectable mixture atop rice or noodles for a comforting meal.

Optional: Drizzle with sesame oil for an extra hint of flavor before serving.

Expert Tips for Pepper Steak with Bell Peppers and Onion

Use High Heat: A hot skillet or wok is crucial to get a nice sear on the flank steak, enhancing its flavor and texture.
Batch Cook Steak: Avoid overcrowding the pan; cook the steak in batches for even browning. This prevents steaming and keeps the meat tender.
Watch Vegetable Texture: Stir-fry vegetables until tender-crisp to maintain their vibrant color and nutritional value. Overcooked veggies can taste soggy and lose their crunch.
Thickening Tip: When mixing cornstarch with water, ensure it’s fully dissolved before adding to the skillet to avoid clumps in your sauce.

Pepper Steak with Bell Peppers and Onion Recipe FAQs

How do I select ripe bell peppers?
Absolutely! When selecting bell peppers for your stir-fry, look for ones that are firm and shiny with vibrant colors. Avoid any that have wrinkles, soft spots, or dark blemishes as these indicate over-ripeness or spoilage. The sweeter the flavor, the better!

What is the best way to store leftover Pepper Steak?
For optimal freshness, store the leftover Pepper Steak with Bell Peppers and Onion in an airtight container in the refrigerator. Consume it within 3 days to enjoy the best flavor and texture. If you’re planning to reheat it, remember to do so gently to keep the vegetables from getting soggy.

Can I freeze Pepper Steak with Bell Peppers and Onion?
Yes! To freeze, let the stir-fry cool completely, then transfer it to a freezer-safe container or resealable bag. Make sure to label it with the date, and it will keep well for up to 3 months. When you’re ready to enjoy it, simply thaw in the refrigerator overnight, then reheat in a skillet over medium heat until warmed through.

What if my steak is tough after cooking?
Very! If your steak ends up chewy, it could be due to slicing against the grain. Always slice flank steak against the grain into thin strips to ensure tenderness. Additionally, marinating the steak for at least 30 minutes allows it to absorb flavors and tenderize, making all the difference in the final dish.

Are there any dietary considerations with this recipe?
Yes, be mindful of dietary restrictions! For a gluten-free option, use gluten-free soy sauce or tamari. If you or someone you’re serving has allergies, make sure to use fresh ingredients and check the labels of all sauces or alternative sweeteners you might incorporate.
