Step‑by‑Step Instructions for Beef and Onion Stir‑Fry

Step 1: Marinate the Beef
In a medium bowl, combine 1 pound of sliced flank steak with 2 tablespoons of soy sauce and 1 tablespoon of cornstarch. Mix well to coat the beef thoroughly and let it marinate for at least 15 minutes at room temperature. This process not only enhances the flavor but also helps tenderize the meat, making it perfect for your Beef and Onion Stir-Fry.

Step 2: Cook the Beef
Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Once the oil is shimmering, add the marinated beef in a single layer. Stir-fry the beef for about 3-4 minutes, or until it turns browned and is no longer pink on the inside. Once cooked, remove the beef from the skillet and set it aside on a plate, keeping it warm.

Step 3: Sauté the Vegetables
In the same skillet, add another tablespoon of vegetable oil. Once heated, toss in the sliced large onion and bell pepper. Stir-fry the vegetables for 2-3 minutes, or until they start to soften and become fragrant. The colors should brighten, signaling they are ready for the next addition in your Beef and Onion Stir-Fry.

Step 4: Add Aromatics
Now, stir in 3 cloves of minced garlic and 1 cup of broccoli florets. Continue to cook for another 2-3 minutes, until the broccoli is bright green and tender-crisp. This step infuses the Beef and Onion Stir-Fry with aromatic goodness, enhancing its flavors!

Step 5: Combine and Finish
Return the cooked beef to the skillet with the vegetables. Add 2 tablespoons of oyster sauce and 1 teaspoon of sesame oil, tossing everything together until well combined. Let this mixture cook for an additional 2 minutes. The sauce should give the ingredients a glossy finish, making the Beef and Onion Stir-Fry irresistible.

Step 6: Serve the Dish
Lastly, plate your Beef and Onion Stir-Fry over a bed of cooked rice. The rice will soak up the delicious sauce, making each bite even more satisfying. Garnish with additional sesame seeds or sliced green onions if desired, and enjoy this homemade meal with family or friends!

Expert Tips for Beef and Onion Stir-Fry

Marination Magic: Let the beef marinate for at least 15 minutes, or up to overnight, to deepen the flavors and enhance tenderness.
Avoid Overcrowding: Stir-fry in batches if necessary; overcrowding the skillet can lead to uneven cooking and steaming instead of browning.
Colorful Veggies: Feel free to swap bell peppers or broccoli with your favorite vegetables like snap peas or carrots for a fun twist in your Beef and Onion Stir-Fry.
Mind the Heat: Keep the skillet at medium-high heat to achieve that perfect sear on the beef without overcooking the veggies.
Seasoning Control: Always taste the stir-fry before serving; adjusting salt and pepper at the end ensures the best flavor tailored to your preference.

Beef and Onion Stir-Fry Variations

Feel free to make this Beef and Onion Stir-Fry your own by exploring these fun twists and substitutions!

Chicken Option: Substitute flank steak with sliced chicken breast for a lighter protein choice. This maintains the same savory flavor with a slightly different texture.
Tofu Swap: For a plant-based meal, replace the beef with firm tofu. Toss the tofu with soy sauce and cornstarch before cooking for that lovely crispy finish.
Vegetable Medley: Boost the nutritional value by adding a mix of your favorite veggies—think snap peas, carrots, or even mushrooms for extra depth.
Spicy Kick: Spice things up by adding fresh chili peppers or a sprinkle of sriracha during cooking. Just a little heat can transform the entire dish!
Gluten-Free Swap: Use gluten-free tamari in place of regular soy sauce and hoisin instead of oyster sauce for a tasty gluten-free option.
Brown Rice Base: Serve your stir-fry over brown rice instead of white for added fiber. It’s a simple swap that enhances the health factor without compromising taste.
Sesame Seeds Twist: Enhance flavor and texture by adding a tablespoon of toasted sesame seeds right before serving. They add a delightful crunch!

Beef and Onion Stir-Fry Recipe FAQs

How do I choose the best beef for this stir-fry?
Absolutely! For this Beef and Onion Stir-Fry, I recommend using flank steak, which is flavorful and tender when cooked quickly. If you can't find flank, sirloin or ribeye work well as substitutes, providing similar texture and taste. Look for cuts with good marbling, as this adds moisture and flavor during cooking, and avoid any beef with dark spots or an off-putting smell.

What’s the best way to store leftovers from this stir-fry?
Very easy! Store any leftover Beef and Onion Stir-Fry in an airtight container in the fridge for up to 3 days. Make sure to allow it to cool to room temperature before sealing. When you're ready to enjoy it again, simply reheat it on the stovetop over medium heat or in the microwave until warmed through.

Can I freeze Beef and Onion Stir-Fry? How?
Of course! You can freeze the stir-fry (without rice) in an airtight container for up to 3 months. To freeze, let the dish cool completely, then place it in the container. To prevent freezer burn, wrap the container tightly in plastic wrap or aluminum foil. When ready to enjoy, thaw it overnight in the fridge and reheat on the stovetop, adding a splash of water or broth to help revive the flavors.

What if my stir-fry is too salty?
No worries! If your stir-fry ends up too salty, there are a few ways to balance the flavor. First, add a bit more cooked broccoli or bell pepper to dilute the saltiness. You could also mix in a splash of unsalted broth or a small amount of sugar to counteract the salt. If you're serving it over rice, the neutral flavor of the rice can also help balance the overall saltiness.

Any dietary considerations I should be aware of?
Yes, it's very important! When making this Beef and Onion Stir-Fry, be mindful of dietary restrictions. The recipe can easily be made gluten-free by using tamari in place of regular soy sauce. If you're concerned about allergies, ensure that the oyster sauce or hoisin sauce you choose is free from allergens like wheat, soy, or shellfish, depending on your needs. For those with red meat restrictions, chicken or tofu are fantastic substitutes!
