Ingredient Breakdown

The key to a great Beef Lo Mein starts with the beef. Cuts like flank steak, sirloin, or ribeye are ideal because they remain tender when cooked quickly at high heat. Slicing the meat thinly against the grain helps lock in juiciness and ensures each bite is melt-in-your-mouth soft.

Lo mein noodles are the backbone of this dish — their slightly chewy texture allows them to soak up every drop of the sauce without turning mushy. If lo mein noodles aren’t available, fresh egg noodles or even spaghetti can be used for a similar texture.

The vegetables bring balance and vibrancy. Carrots and broccoli provide crunch and color, while onions add subtle sweetness. This mix creates the perfect contrast to the tender beef and silky noodles. Garlic serves as the aromatic anchor, infusing the stir-fry with an irresistible fragrance that ties all the ingredients together.

The sauce is what truly defines this dish — a harmonious blend of soy sauce, brown sugar, sesame oil, and Beef Better Than Bouillon. This combination delivers deep umami notes, a touch of sweetness, and a glossy coating that clings beautifully to the noodles.

Step-by-Step Preparation Guide

Start by preparing the sauce. Dissolve the beef bouillon and brown sugar in hot water, then stir in soy sauce for a savory-sweet base that forms the heart of the dish. Set it aside to let the flavors meld while you work on the rest of the ingredients.

The next step is preparing the beef. Heat a wok or skillet over medium-high heat with a drizzle of sesame oil, then quickly sear the beef in batches. The goal is to caramelize the exterior while keeping the inside tender. Once browned, remove the beef and set it aside to prevent overcooking.

Using the same pan, sauté the onions until they become fragrant and slightly golden. Remove them, then cook the carrots until just tender, followed by the broccoli, which should remain vibrant and crisp. Return the onions to the pan, press in the garlic, and stir everything together until the aroma deepens.

Now it’s time to bring everything together. Add the beef back into the skillet, pour in the prepared sauce, and toss well to coat all the ingredients. Let it simmer for a minute or two to thicken slightly and infuse the beef and vegetables with flavor.

Finally, add the cooked noodles. Toss everything thoroughly, making sure each strand is coated in the savory sauce and mixed evenly with the beef and vegetables. The dish should look glossy and richly colored, with a perfect balance of textures.

Recipe Tips

Cutting the beef thinly against the grain for maximum tenderness.

Using a hot wok or skillet to create authentic stir-fry texture.

Avoiding soggy noodles by cooking them just until al dente.

Making extra sauce for a saucier version or adjusting sweetness with more soy or sugar.

What to Serve With This Recipe

Pair Beef Lo Mein with classic Asian sides for a complete meal. Crispy egg rolls or potstickers make excellent companions, adding crunch and variety. A bowl of steamed jasmine or fried rice can complement the noodles and soak up any extra sauce. For a lighter touch, serve it alongside a crisp cucumber salad or sesame slaw to balance the richness. A simple miso soup or clear broth also makes a refreshing start to the meal, rounding out the flavors beautifully.

Creative Variations

This versatile dish welcomes endless variations. For a lighter option, substitute the beef with chicken or shrimp — both absorb the sauce wonderfully. A vegetarian version works just as well with tofu or extra vegetables like mushrooms, snow peas, and bell peppers. Spice enthusiasts can add chili flakes, sriracha, or hot sesame oil for a fiery twist. For extra crunch, garnish with toasted sesame seeds or crushed peanuts just before serving.

Ingredients

1 lb beef, thinly sliced into strips
8 oz lo mein noodles, cooked according to package directions
2 large carrots, cut into thin matchsticks
2 cups broccoli florets
1 large onion, sliced
4 garlic cloves, minced or pressed
1 tsp sesame oil
Oil (olive or sesame) for frying
1/4 cup hot boiled water
1 tbsp Beef Better Than Bouillon
3 tbsp soy sauce
2 tbsp brown sugar

Instructions

In a small bowl, combine the hot boiled water, Beef Better Than Bouillon, and brown sugar. Stir until completely dissolved, then mix in the soy sauce to create a rich, savory-sweet sauce. Set aside.

Heat a large skillet or wok over medium-high heat and drizzle in sesame oil. Add the sliced beef and cook for 3–4 minutes, stirring occasionally, until browned and caramelized. Remove the beef from the pan and set aside.

In the same skillet, add a little more sesame or olive oil if needed. Sauté the sliced onions until golden and fragrant, about 3 minutes, then remove and set aside. Add the carrots to the skillet and cook until slightly tender. Stir in the broccoli and continue cooking for another 2–3 minutes until just softened but still vibrant in color. Return the onions to the pan and press in the garlic, stirring to blend the flavors together.

Add the cooked beef back to the skillet and pour the prepared sauce over the mixture. Toss everything to coat evenly and allow it to simmer for about 2 minutes, letting the flavors meld and the sauce thicken slightly.

Add the cooked lo mein noodles to the pan and toss well to combine the beef, vegetables, and sauce. Continue tossing for 1–2 minutes until everything is evenly mixed and heated through.

Transfer to a large serving dish and serve immediately while hot. Each bite delivers a perfect balance of tender beef, crisp vegetables, and flavorful noodles coated in a glossy, savory-sweet sauce.
