Easy Beef Stir Fry Recipe

This Easy Beef Stir Fry is a great choice when you want a flavorful homemade dinner without spending a lot of time in the kitchen. Thinly sliced beef is quickly seared with colorful bell peppers, onion, garlic, and ginger, then tossed in a savory sauce with hoisin or oyster sauce, soy sauce, rice vinegar, and a touch of sweetness.

Ingredients

For the Beef

• 20 oz beef steak, such as flank steak, skirt steak, or flat iron steak
• 1 tablespoon sesame oil
• 1 teaspoon cornstarch
• ½ teaspoon baking soda
• ½ teaspoon sea salt

For the Sauce

• 3 tablespoons hoisin sauce or oyster sauce
• 2 tablespoons soy sauce, regular or low-sodium
• 2 tablespoons rice vinegar, apple cider vinegar, or Shaoxing wine
• 1 tablespoon brown sugar, honey, maple syrup, or a sugar alternative

For the Cornstarch Slurry

• 1 tablespoon cornstarch, arrowroot flour, or tapioca starch
• 1 tablespoon water

For the Stir Fry

• 11 oz mixed-color bell peppers, sliced
• 4 oz onion, 1 small, sliced
• 1.4 oz green onions, sliced
• ¼ cup vegetable oil or canola oil
• 0.3 oz garlic, about 2 cloves, minced
• 0.2 oz ginger, about ½ tablespoon, minced

Step-by-Step Instructions

1. Slice the Beef

For the most tender beef, slice the steak thinly against the grain. If the steak is difficult to slice, place it in the freezer for about 15–20 minutes first. This firms it up and makes thin slicing easier.

2. Season and Tenderize the Beef

Place the sliced beef in a bowl. Add the sesame oil, cornstarch, baking soda, and sea salt. Toss well until the beef is evenly coated.

Let it sit for about 10–15 minutes while you prepare the vegetables and sauce.

3. Make the Sauce

In a small bowl, whisk together the hoisin sauce or oyster sauce, soy sauce, rice vinegar, and brown sugar.

Set the sauce aside.

4. Prepare the Cornstarch Slurry

Mix 1 tablespoon cornstarch with 1 tablespoon water in a small bowl. Stir until smooth and there are no dry lumps.

5. Cook the Beef

Heat a large wok or skillet over medium-high to high heat. Add about half of the vegetable oil.

Once the pan is hot, add the beef in a single layer. Cook in batches if necessary so the pan doesn’t become overcrowded.

Sear the beef quickly until browned and nearly cooked through, about 2–3 minutes per side depending on thickness. Transfer the beef to a clean plate.

6. Stir Fry the Vegetables

Add the remaining oil to the same pan. Add the sliced onion and bell peppers.

Stir fry for about 3–4 minutes, keeping the vegetables slightly crisp.

Add the garlic and ginger and cook for another 30–60 seconds, just until fragrant.

7. Add the Beef and Sauce

Return the beef to the pan. Pour in the prepared sauce and toss everything together.

Stir the cornstarch slurry once more, then pour it into the pan while tossing continuously.

Cook for about 1–2 minutes, until the sauce thickens and coats the beef and vegetables.

8. Finish with Green Onions

Add the green onions and toss everything together. Cook for another 30 seconds, then remove the pan from the heat.

Serve immediately.

Recipe Tips for Success

• Slice against the grain: This is one of the easiest ways to make steak more tender.
• Don’t overcrowd the pan: Too much beef at once can cause it to steam instead of sear.
• Get the pan hot first: Stir fry cooking works best with high heat and quick cooking.
• Don’t overcook the beef: Thin slices need only a short time to cook.
• Prep everything beforehand: Once the wok is hot, the recipe moves quickly.
• Add the slurry at the end: This gives the sauce its glossy, thicker consistency without making it too heavy.
• Keep the vegetables slightly crisp: Bell peppers and onions add better texture when they aren’t overcooked.

Ingredient Substitutions

Beef

Flank steak, skirt steak, and flat iron steak are all good choices. Pre-sliced stir-fry beef can also be used, although tenderness can vary.

Soy Sauce

Use low-sodium soy sauce if you prefer a less salty stir fry. For a gluten-free option, use tamari or coconut aminos.

Hoisin or Oyster Sauce

Use whichever you have available. Hoisin sauce gives the dish a slightly sweeter flavor, while oyster sauce provides a deeper savory taste.

Vinegar

Rice vinegar is the best fit, but apple cider vinegar or Shaoxing wine can also work.

Sweetener

Brown sugar can be replaced with honey or maple syrup.

Cornstarch

Arrowroot flour or tapioca starch can be used instead of cornstarch for thickening.

Recipe Variations

Spicy Beef Stir Fry

Add red pepper flakes, chili garlic sauce, or sliced fresh chili peppers to the sauce.

Beef and Broccoli Stir Fry

Add broccoli florets along with the bell peppers for a classic combination.

Mushroom Beef Stir Fry

Add sliced mushrooms for extra savory flavor and texture.

Extra Vegetable Stir Fry

Add carrots, snap peas, zucchini, or baby corn to make the meal more vegetable-forward.

Noodle Beef Stir Fry

Toss the finished beef and vegetables with cooked noodles for a complete one-pan noodle dinner.

Storage and Reheating

Store leftover beef stir fry in an airtight container in the refrigerator for up to 3–4 days.

Reheat gently in a skillet over medium heat until warmed through. You can add a small splash of water if the sauce has thickened too much.

The stir fry can also be reheated in the microwave in short intervals, stirring between each interval.
