Instructions

Recipe For Beef Stir Fry With Peppers And Onions

Step 1: Marinate the Beef

In a mixing bowl, combine the thinly sliced beef with soy sauce and cornstarch. Let it marinate for at least 15 minutes. This not only flavors the beef but also tenderizes it, ensuring every bite is succulent. Tip: For even more flavor, let the beef marinate for up to an hour in the fridge.

Step 2: Prep the Vegetables

While the beef is marinating, slice the onion and bell peppers into even strips. Mince the garlic and grate the ginger. Having all your ingredients prepped and ready to go makes the cooking process smoother and faster.

Step 3: Stir Fry the Beef

Heat 1 tbsp of vegetable oil in your wok or skillet over high heat. Add the beef in a single layer, working in batches if necessary to avoid overcrowding. Cook for about 2-3 minutes per side until just browned but not fully cooked through. Remove the beef and set aside. Tip: Don’t stir the beef too much; letting it sit ensures a good sear.

Step 4: Cook the Vegetables

In the same wok, add the remaining 1 tbsp of oil. Toss in the onions and bell peppers, stirring frequently for about 4-5 minutes until they start to soften but still retain some crunch. Add the garlic and ginger, cooking for an additional 30 seconds until fragrant.

Step 5: Combine Everything

Return the beef to the wok along with any accumulated juices. Pour in the beef broth and hoisin sauce, stirring to coat everything evenly. Cook for another 2-3 minutes until the sauce thickens slightly and the beef is fully cooked. Drizzle with sesame oil before serving for an extra layer of flavor.

Tips and Tricks

For the best stir fry, ensure your wok or skillet is very hot before adding ingredients. This high heat is key to achieving that signature stir fry texture and flavor. If you’re using a thinner cut of beef, reduce the cooking time to prevent it from becoming tough. Experiment with different vegetables like broccoli or snap peas for variety. Lastly, don’t skip the sesame oil at the end; its nutty aroma elevates the dish.

Recipe Variations

  • Swap the beef for chicken or shrimp for a different protein option.
  • Add a spicy kick by including sliced chili peppers or a dash of red pepper flakes.
  • For a sweeter version, add pineapple chunks and a bit of honey to the sauce.
  • Make it gluten-free by using tamari instead of soy sauce.
  • Include mushrooms or zucchini for additional vegetables.

Frequently Asked Questions

Can I use a different cut of beef?

Absolutely! While sirloin is recommended for its tenderness and flavor, you can also use flank steak or ribeye. Just be sure to slice it thinly against the grain to ensure it stays tender after cooking.

How can I make this dish spicier?

To add heat, incorporate some sliced jalapeños or serrano peppers during the vegetable cooking step. Alternatively, a spoonful of sriracha or chili garlic sauce can be mixed into the sauce for an extra kick.

Can I prepare this dish ahead of time?

While stir fry is best enjoyed fresh, you can prep all the ingredients ahead of time and store them separately in the fridge. When ready to eat, simply cook as directed. The actual cooking process is so quick, it’s perfect for last-minute meals.

This beef stir fry with peppers and onions is a quick, flavorful, and versatile dish perfect for any weeknight. With simple ingredients and easy steps, it’s a foolproof recipe that’s sure to impress.
