What Kind of Noodles Work Best for Beef Lo Mein?

Lo mein traditionally uses egg noodles, which are chewy, slightly thick, and perfect for absorbing savory sauces. If you can’t find lo mein noodles, substitute with yakisoba, ramen noodles (discard the flavor packet), or even spaghetti in a pinch. The key is to cook the noodles al dente and toss them quickly with the sauce so they don’t get soggy.

Ingredients for the Savory Beef Lo Mein with Vegetables

Beef sirloin (thinly sliced): This lean cut cooks fast and stays tender, making it ideal for stir-frying.

Lo mein noodles: Absorb all the bold flavors and provide that comforting, slurp-worthy texture.

Broccoli florets: Add crunch and vibrant green color.

Carrots (sliced): Sweetness and color contrast beautifully with the beef.

Bell peppers (green and red): A pop of sweetness and slight tang that balances the savory sauce.

Onion (sliced): Adds depth and sweetness to the stir-fry base.

Garlic (minced): A must for layering flavor.

Soy sauce: The backbone of the sauce, giving saltiness and umami.

Oyster sauce: Adds complexity and a slight sweetness that clings to the noodles.

Sesame oil: A finishing touch for nuttiness and aroma.

Cornstarch + water slurry: Helps thicken the sauce so it coats everything nicely.

Olive or vegetable oil: For stir-frying.

How To Make the Savory Beef Lo Mein with Vegetables

Step 1: Prep the Ingredients

Slice your beef sirloin thinly against the grain and chop all vegetables into bite-sized pieces. Have your sauces and cornstarch slurry ready to go for smooth cooking.

Step 2: Cook the Noodles

Cook lo mein noodles according to the package instructions. Drain and rinse under cold water to stop the cooking process, then toss with a tiny splash of sesame oil to prevent sticking.

Step 3: Sear the Beef

Heat a tablespoon of oil in a large wok or skillet over medium-high heat. Add the beef slices in a single layer and sear for 1-2 minutes on each side until browned. Remove from the pan and set aside.

Step 4: Stir-Fry the Vegetables

In the same pan, add a bit more oil if needed. Toss in the garlic and onions first, followed by carrots, broccoli, and bell peppers. Stir-fry for 3-4 minutes until veggies are tender-crisp but still vibrant.

Step 5: Combine and Sauce It Up

Return the beef to the pan along with the cooked noodles. Pour in the soy sauce, oyster sauce, and cornstarch slurry. Toss everything together quickly so the sauce thickens and evenly coats all the ingredients.

Step 6: Finish with Sesame Oil

Drizzle a small amount of sesame oil over the finished lo mein for that signature nutty aroma. Serve immediately while hot and saucy.

How to Serve and Store This Savory Beef Lo Mein

Serve your beef lo mein hot, straight from the skillet to the plate. It pairs perfectly with a side of steamed dumplings or a light cucumber salad to balance the richness. Garnish with sesame seeds or chopped green onions for a fresh crunch.

To store leftovers, let the lo mein cool completely before transferring to an airtight container. It keeps well in the fridge for up to 4 days. Reheat in a skillet with a splash of water or broth to loosen up the sauce.

Frequently Asked Questions

Can I use another type of meat?

Yes! Chicken, shrimp, or even tofu work wonderfully in place of beef. Just adjust cooking times accordingly.

What vegetables can I swap in?

Snap peas, baby corn, mushrooms, or cabbage are all great alternatives. Use whatever you have on hand.

Can I make this gluten-free?

Absolutely. Use tamari instead of soy sauce, and make sure your noodles and oyster sauce are certified gluten-free.

How do I keep the noodles from getting soggy?

Be sure not to overcook the noodles and always toss them with sauce over high heat to prevent mushiness.

Can this dish be made ahead?

It’s best served fresh, but you can prep the sauce, meat, and veggies ahead of time and keep them in the fridge until ready to stir-fry.

Do I need a wok?

Nope! A large nonstick or stainless steel skillet works just as well for stir-frying.
