Why You’ll Love This Recipe

• It’s really easy to make. After stir-frying the beef, stir-fry the vegetables and combine them all together. It’ll come together in no time.
• I won’t claim that this recipe uses only pantry staples, as I usually have to grab some snap peas and a bell pepper at the store, but you can make this stir fry with any veggies you have on hand. The sauce is made with pantry staples, though! I always keep soy sauce, sesame oil, oyster sauce, and cornstarch on hand.
• Leftovers keep really well. It’s perfect for meal prepping!

Ingredients You’ll Need

• flank steak — I love using flank steak, but you can also use skirt steak or rib eye. You don’t want to use anything too lean or tough. I don’t cut them too thinly, so they still have a nice meaty texture when I bite into them.
• soy sauce — I recommend using light sodium soy sauce. You’ll need it to marinate the steak and make the sauce for the noodles.
• sesame oil — this adds a nice flavor and you’ll be cooking the beef and vegetables in it. You can also stir fry the beef and veggies with avocado or olive oil if you prefer.
• oyster sauce — don’t worry, while it’s made from oyster extract, it doesn’t taste like oysters or fishy! I have a post sharing what oyster sauce is if you’re curious.
• cornstarch — coating the sliced steak in cornstarch helps tenderizes and protect the beef from overcooking.
• onion — I use a small sweet onion but feel free to use a yellow onion.
• red pepper — I like the sweetness and crunch you get from a sliced red pepper. Feel free to use a different colored bell pepper but keep in mind that red is the sweetest and green is the least.
• snap peas — I’m using snap peas because again of their sweetness and crunch factor. Snow peas are a great alternative but are a little less sweet.

How to Make Stir Fry Beef with Oyster Sauce

• Add soy sauce, sesame oil, water, oyster sauce, and cornstarch to the sliced flank steak.
• Mix until combined. Set aside in the fridge for 20 minutes.

• Heat up a tablespoon of oil in a large skillet over medium heat and add the marinaded beef to it in a single layer. Cook for about 2 to 3 minutes per side.
• Set the beef aside. Depending on the size of your skillet, you may have to do it in batches.

• Give the skillet a quick wipe with a paper towel and add another tablespoon of oil to the pan. Add the sliced onions and saute them for 2 minutes and then add the sliced bell peppers and snap peas. Saute for another 2 to 3 minutes, depending on how tender you’d like the bell pepper and snap peas to be.
• Add the beef back to the skillet and add ¼ cup of oyster sauce to the beef and vegetables. Toss to combine. Garnish with sesame seeds and green onions if desired.

Recipe Tips and Notes

• If you’re having trouble slicing the beef, you can freeze the flank steak for around 20 minutes. This helps the steak firm up enough that you can effortlessly slice through the steak.
• I find it’s easiest to wear a pair of gloves and massage the marinade into the beef. It is super easy to help coat the beef evenly.
• When slicing the steak, make sure to slice against the grain so the steak is tender.
• I usually serve this beef and vegetable stir fry with jasmine rice. But you can also try serving it with coconut rice, noodles, or in a lettuce cup!
• Shiitake mushrooms make for a great addition to the stir fry as well as they have a great meaty texture. Add them after adding the onions.
• This is the skillet I used to make this stir fry.

Make Ahead Tips

• Meal prep: once cooled, store the beef and veggies with oyster sauce in an airtight container for up to 4 days in the fridge.
• Reheat: you can reheat leftovers in the microwave or on the stove top over medium heat with a bit of oil.
