Ingredients

For the Beef

• 500 g (about 1.1 lb) beef steak, thinly sliced
• 1 tablespoon soy sauce
• 1 tablespoon cornstarch
• 1 teaspoon sesame oil
• 1 teaspoon vegetable oil
• ½ teaspoon black pepper
• ½ teaspoon salt

For the best texture, choose a tender cut of beef such as sirloin, ribeye, flank steak, or beef tenderloin.

For the Stir Fry

• 2 large yellow onions, thinly sliced
• 3 cloves garlic, finely minced
• 1 teaspoon fresh ginger, finely grated
• 2 tablespoons vegetable oil, divided
• 1 tablespoon sesame oil
• 2 green onions, thinly sliced
• 1 teaspoon sesame seeds, optional

For the Stir Fry Sauce

• 3 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 tablespoon honey or brown sugar
• 1 tablespoon rice vinegar
• ½ cup beef broth or water
• 1 teaspoon cornstarch
• ½ teaspoon sesame oil
• ½ teaspoon black pepper
• ¼ teaspoon red pepper flakes, optional

Choosing the Best Beef

The type of beef you use can make a big difference in the final texture.

Sirloin is one of the best choices for this recipe because it is tender, flavorful, and easy to find. Ribeye will give you a richer flavor because of its marbling, while flank steak is also excellent when sliced correctly.

If you are using flank steak, make sure you slice it very thinly against the grain.

The grain refers to the direction in which the muscle fibers run. Cutting across those fibers shortens them, making the beef much more tender and easier to chew.

A useful trick is to place the beef in the freezer for approximately 15–20 minutes before slicing. The meat becomes slightly firmer, making it much easier to cut into thin, even strips.

How to Make Tender Beef Stir Fry with Onions

Step 1: Slice the Beef

Start by trimming any large pieces of excess fat or tough connective tissue from the beef.

Place the beef in the freezer for 15–20 minutes if necessary.

Using a sharp knife, slice the beef into very thin strips, approximately 3–5 mm thick.

Make sure you slice against the grain. This simple step can make a huge difference in how tender the beef feels when you eat it.

Place the sliced beef into a medium-sized bowl.

Step 2: Marinate the Beef

Add the soy sauce, cornstarch, sesame oil, vegetable oil, black pepper, and salt to the beef.

Mix thoroughly until every piece of beef is evenly coated.

Let the beef rest for at least 10–15 minutes.

The cornstarch creates a light coating around the beef. It helps protect the meat from drying out while cooking and also gives it a beautiful texture when seared.

If you have extra time, you can let the beef marinate for up to 30 minutes in the refrigerator.

Step 3: Prepare the Sauce

While the beef is marinating, prepare the stir-fry sauce.

In a small bowl, combine the soy sauce, oyster sauce, honey or brown sugar, rice vinegar, beef broth, cornstarch, sesame oil, black pepper, and red pepper flakes.

Whisk everything together until the cornstarch is completely dissolved.

Set the sauce aside.

It is important to mix the sauce again just before adding it to the pan because the cornstarch can settle at the bottom of the bowl.

Step 4: Prepare the Vegetables

Thinly slice the onions.

Finely mince the garlic and grate the fresh ginger.

Slice the green onions and set them aside for garnish.

Preparing all of your ingredients before cooking is especially helpful with stir-fry recipes because the cooking process moves very quickly.

Step 5: Sear the Beef

Place a large wok or heavy skillet over high heat.

Allow the pan to become very hot before adding the oil.

Add 1 tablespoon of vegetable oil.

Add the beef in a single layer.

Do not overcrowd the pan. If your pan is small, cook the beef in two batches.

Cook the beef for approximately 1–2 minutes on the first side, then stir or flip the pieces and cook for another 1–2 minutes.

The outside should become nicely browned while the inside remains tender and juicy.

Transfer the beef to a clean plate and set it aside.

Do not worry if the beef is not completely cooked through at this stage. It will finish cooking when it is returned to the pan with the sauce.

Step 6: Cook the Onions

Using the same pan, add the remaining tablespoon of vegetable oil.

Add the sliced onions.

Cook over medium-high to high heat for approximately 4–6 minutes, stirring occasionally.

The onions should become soft and lightly golden around the edges.

You do not want them to completely disappear into the sauce. Keeping some texture in the onions makes the finished dish much more enjoyable.

Step 7: Add Garlic and Ginger

Add the minced garlic and freshly grated ginger to the onions.

Stir continuously and cook for approximately 30–60 seconds.

You should immediately notice the beautiful aroma of garlic and ginger.

Be careful not to cook the garlic for too long because burnt garlic can become bitter.

Step 8: Add the Beef Back to the Pan

Return the seared beef to the pan with the onions, garlic, and ginger.

Give the prepared sauce another good stir.

Pour the sauce over the beef and onions.

Increase the heat slightly and toss everything together.

Cook for approximately 1–2 minutes, stirring constantly.

The sauce will begin to bubble and thicken because of the cornstarch.

Continue cooking until the sauce becomes glossy and coats the beef and onions.

Step 9: Finish the Stir Fry

Once the sauce has thickened, turn off the heat.

Drizzle the remaining sesame oil over the stir fry.

Garnish with sliced green onions and sesame seeds.

For extra heat, you can add a small amount of chili oil, crushed red pepper, or thinly sliced fresh chili peppers.

How to Serve Beef Stir Fry

This beef stir fry is best served immediately while everything is hot.

The classic option is to serve it over a bowl of fluffy steamed white rice.

You can also serve it with:

• Jasmine rice
• Basmati rice
• Brown rice
• Fried rice
• Egg noodles
• Rice noodles
• Udon noodles
• Steamed vegetables

For a lighter meal, serve the beef and onions with steamed broccoli, bok choy, green beans, or a fresh cucumber salad.

The savory sauce also makes an excellent topping for rice because it soaks into the grains and adds plenty of flavor.

Tips for Making Extra-Tender Beef

Slice Against the Grain

This is one of the most important tips.

Look carefully at the beef and identify the direction of the muscle fibers. Slice across those fibers rather than in the same direction.

Slice the Beef Thinly

Thin slices cook very quickly, which helps prevent the beef from becoming tough.

A partially frozen piece of beef is much easier to slice thinly.

Use a Very Hot Pan

Stir-frying works best when the pan is very hot.

A hot pan allows the beef to develop a beautiful brown crust quickly without spending too much time cooking.

Cook in Batches

If you add too much beef to the pan at once, the temperature will drop.

Instead of searing, the beef will release moisture and begin to steam.

Cooking in small batches gives you better browning and a much better texture.

Avoid Overcooking

Thin beef cooks very quickly.

Once the beef is browned, remove it from the pan. It will finish cooking later when you combine it with the sauce.

Easy Vegetable Additions

This recipe is delicious with just beef and onions, but you can easily add vegetables to make it even more colorful and nutritious.

Some excellent choices include:

Bell Peppers

Red, yellow, and green bell peppers add sweetness, color, and crunch.

Broccoli

Cut the broccoli into small florets and cook until tender-crisp.

Mushrooms

Mushrooms add a rich, earthy flavor that works beautifully with the beef.

Carrots

Thinly sliced carrots add natural sweetness and a little crunch.

Snow Peas

Snow peas cook quickly and add a fresh, crisp texture.

Green Beans

Cut the green beans into smaller pieces and stir-fry them until slightly tender.

Baby Corn

Baby corn adds a nice crunch and makes the dish look especially colorful.

Variations

Spicy Beef Stir Fry

For a spicy version, add 1–2 teaspoons of chili sauce, chili oil, or sriracha to the stir-fry sauce.

You can also add sliced fresh chili peppers.

Sweet and Savory Beef Stir Fry

If you prefer a sweeter sauce, increase the honey or brown sugar to 1½–2 tablespoons.

This creates a delicious sweet-and-savory combination.

Beef and Broccoli Stir Fry

Add approximately 2 cups of broccoli florets.

Cook the broccoli before adding the beef back to the pan, then continue with the sauce as directed.

Ginger Beef Stir Fry

For a stronger ginger flavor, increase the fresh ginger to 1½ tablespoons.

Fresh ginger adds a wonderful warmth and fragrance to the dish.

Storage

Allow the leftover beef stir fry to cool slightly before transferring it to an airtight container.

Store it in the refrigerator for up to 3 days.

For the best texture, reheat the leftovers in a skillet over medium-high heat.

Add a small splash of water or beef broth if the sauce has become too thick.

You can also microwave the leftovers, but avoid overheating them because the beef may become tougher.

Can You Freeze Beef Stir Fry?

Yes, you can freeze this dish.

Allow it to cool completely before transferring it to a freezer-safe container.

Freeze for up to approximately 2 months for the best quality.

Thaw overnight in the refrigerator and reheat gently in a skillet.

Keep in mind that the onions may become slightly softer after freezing and thawing, but the flavor will still be delicious.
