Step‑by‑Step Instructions for Beef Stir-Fry with Vegetables
Step 1: Marinate Beef
In a large bowl, combine thinly sliced flank steak with cornstarch, 1 tablespoon of neutral oil, a pinch of baking soda, and 2 tablespoons of water. Mix well until the beef is evenly coated. Allow the beef to marinate for at least 30 minutes, or even overnight if you have the time, to ensure it’s tender and flavorful.
Step 2: Prepare Vegetables
While the beef marinates, chop the bok choy, mushrooms, and sugar snap peas into bite-sized pieces. Set them aside in separate bowls, ensuring you have all your vegetables prepped and ready to go. This makes the stir-fry process much quicker, as you’ll want everything to be within reach when you start cooking the Beef Stir-Fry with Vegetables.
Step 3: Make the Sauce
In a medium bowl, whisk together ¼ cup of warm water or beef stock, 1 tablespoon of sesame oil, 1 tablespoon each of light and dark soy sauce, and 2 tablespoons of oyster sauce. Stir well until combined. This savory sauce will add depth and flavor to your dish, making your Beef Stir-Fry truly delightful.
Step 4: Heat Wok
Preheat your wok over high heat until it begins to smoke lightly, which should take about 2-3 minutes. Once it’s hot, add 2 tablespoons of neutral oil, ensuring the oil coats the surface evenly. The high temperature is crucial for achieving that characteristic stir-fry sizzle and perfect texture.
Step 5: Sear Beef
Carefully add the marinated beef to the wok in a single layer. Let it sear for 30 seconds without stirring, allowing a nice browning to form. Afterward, flip the beef and sear for another 30 seconds or until it’s about 80% cooked. Remove the beef from the wok and set it aside while keeping the heat high.
Step 6: Stir-Fry Aromatics
Pour in an additional tablespoon of neutral oil to the wok, followed by minced garlic and ginger. Sauté the aromatics for about 15 seconds, stirring constantly until fragrant. This step infuses your Beef Stir-Fry with Vegetables with vibrant flavors, creating a tantalizing aroma that fills your kitchen.
Step 7: Cook Vegetables
Quickly add the mushrooms to the wok, stir-frying them for around 15 seconds until they start to soften. Next, toss in the chopped bok choy and sugar snap peas, continuing to cook for an additional 20 seconds. The vegetables should remain vibrant and slightly crisp, adding texture to your delicious stir-fry.
Step 8: Combine Everything
Return the seared beef to the wok, then pour the previously prepared sauce mixture over the entire stir-fry. Use a spatula to stir quickly and evenly coat the beef and vegetables with the sauce, allowing it to heat through and thicken slightly—this should take about 30 seconds.
Step 9: Thicken Sauce
As you stir, gradually add a cornstarch slurry (made by mixing 1 teaspoon of cornstarch with 1 tablespoon of water) to the wok. Keep stirring for another 20 seconds, or until the sauce thickens and clings to the ingredients, creating that delectable coating that enhances the Beef Stir-Fry with Vegetables.
Step 10: Serve
Once everything is cooked through and the sauce is glossy, transfer your Beef Stir-Fry to a serving dish. Serve immediately, ideally over a bed of steamed rice or alongside noodles, allowing you and your loved ones to enjoy a hearty meal bursting with flavor and freshness.

Make Ahead Options
These Beef Stir-Fry with Vegetables are perfect for busy weeknights when you want a delicious meal with minimal fuss! You can marinate the flank steak up to 24 hours in advance, which not only saves time but also enhances the flavor. Additionally, prepare your vegetables by washing and chopping them at least a few hours ahead. Store the chopped veggies in an airtight container in the refrigerator to maintain their crunch and freshness. When you’re ready to serve, simply heat your wok, stir-fry the aromatics, and cook the prepped beef and vegetables together for a quick finishing touch. This way, you’ll have a scrumptious meal on the table in no time—just as delightful as if you made it fresh!

Beef Stir-Fry with Vegetables Recipe FAQs
How do I choose the right flank steak?
Absolutely! Look for flank steak that is bright red, with minimal dark spots, which indicate freshness. It should feel firm to the touch and be well-marbled but not overly fatty. If you have a butcher you trust, don’t hesitate to ask for their recommendations!
How should I store leftovers?
Very easy! Store any leftover Beef Stir-Fry in an airtight container in the refrigerator for up to 3 days. If you want to keep the veggies crispy, it’s best to store them separate from the beef and sauce if possible. When ready to enjoy, just reheat in a skillet or microwave.
Can I freeze Beef Stir-Fry?
Absolutely! To freeze, allow the stir-fry to cool completely, then transfer to a freezer-safe container. It can be frozen for up to 3 months, but for the best quality, enjoy within 1 month. When you’re ready to eat, thaw it in the fridge overnight and reheat in a pan, adding a splash of water if the sauce is too thick.
What if my beef turns out tough?
If your beef is tough, you might not have sliced it against the grain or marinated it long enough. Always cut flank steak against the grain into thin strips for tenderness; this breaks up the muscle fibers. If you prefer, you can marinate the beef overnight, allowing it to absorb all the flavors and become incredibly juicy.
Can I use different vegetables?
Very much so! One of the fantastic aspects of Beef Stir-Fry is its flexibility. You can swap in any seasonally available vegetables like bell peppers, broccoli, or zucchini. Just make sure to chop them into similar-sized pieces for even cooking; you want each veggie to maintain its crunch!
Are there any dietary considerations for this dish?
Good question! This Beef Stir-Fry includes ingredients that are generally safe for most people, but always check for allergies to specific components such as soy sauce or shellfish in oyster sauce. For a gluten-free option, you can substitute soy sauce with tamari or coconut aminos, and use hoisin sauce instead of oyster sauce for a vegetarian-friendly version.
