Ingredients
Gathering your ingredients is the first step to lo mein bliss! Here’s what you’ll need:
For the Beef:
- 1 lb beef sirloin, thinly sliced: I love sirloin for its tenderness, but flank steak or even a good cut of chuck would work too. Slice it against the grain for maximum tenderness!
- 2 tablespoons soy sauce: The foundation of our marinade, giving the beef that savory depth.
- 1 tablespoon cornstarch: This little secret helps tenderize the beef and creates a lovely coating that holds onto flavor.
- 1 tablespoon vegetable oil: Just a touch to help with searing.
For the Lo Mein:
- 8 oz lo mein noodles or spaghetti: Fresh lo mein noodles are amazing if you can find them, but good old spaghetti or even linguine works perfectly fine in a pinch.
- 2 tablespoons vegetable oil: For sautéing all those yummy aromatics and veggies.
- 1 onion, thinly sliced: Adds a sweet and savory base to our stir-fry.
- 2 cloves garlic, minced: Because what’s a savory dish without garlic?
- 1 cup sliced carrots: For a touch of sweetness and a lovely crunch.
- 1 cup sliced bell peppers (red, green, or yellow): I like to use a mix for beautiful color and slightly different flavors.
- 1 cup broccoli florets: Adds a healthy green boost and a nice texture.
- 1 cup snow peas: These add a delightful snap and fresh, green flavor.
- 1/4 cup soy sauce: More of that essential savory goodness for the sauce.
- 2 tablespoons oyster sauce: This is a game-changer for umami flavor! If you can’t find it, a touch more soy sauce can work, but it’s worth seeking out.
- 1 teaspoon sesame oil: For that authentic, nutty aroma and taste. A little goes a long way!
- 1/4 cup beef broth: Helps create a luscious sauce. Chicken broth works too!
- 1 tablespoon cornstarch mixed with 1 tablespoon water (slurry): Our thickening magic for the sauce.
- Green onions, chopped (for garnish): Freshness and a pop of green at the end.
- Sesame seeds (optional, for garnish): A little sprinkle adds a nice visual touch and a subtle nutty crunch.
How to Make It
Alright, let’s get cooking! This is where the magic happens, and it’s surprisingly straightforward.
-
Marinate the beef:
In a medium bowl, toss your thinly sliced beef with 2 tablespoons of soy sauce and 1 tablespoon of cornstarch. Give it a good mix so every piece is coated. Let this little party sit for at least 15 minutes while you get the other ingredients ready. This step is crucial for tender, flavorful beef!
-
Cook the noodles:
Get a pot of water boiling and cook your lo mein noodles (or spaghetti) according to the package instructions. Once they’re perfectly al dente, drain them well and set them aside. A little toss with a tiny bit of oil can prevent them from sticking if you’re not adding them to the pan right away.
-
Stir-fry the beef:
Heat 1 tablespoon of vegetable oil in a large skillet or, even better, a wok, over medium-high heat. Once it’s nice and hot, add your marinated beef in a single layer (you might need to do this in batches to avoid crowding the pan!). Sear it until it’s beautifully browned. Don’t overcook it – we just want it mostly cooked through at this stage. Scoop the beef out and set it aside with the cooked noodles.
-
Sauté the vegetables:
Add the remaining 2 tablespoons of vegetable oil to the same skillet. Toss in your sliced onion and cook for about 2-3 minutes until it starts to soften and smell amazing. Then, add your minced garlic and cook for just another minute until it’s fragrant. Be careful not to burn the garlic!
-
Add remaining vegetables:
Now, bring on the color! Add your carrots, bell peppers, broccoli florets, and snow peas to the skillet. Stir-fry these for about 5-7 minutes. You want them to be tender but still have a nice bit of crunch – that’s what we call “tender-crisp” and it’s perfect for lo mein.
-
Combine sauce ingredients:
While the veggies are doing their thing, whisk together the sauce ingredients in a small bowl: 1/4 cup soy sauce, 2 tablespoons oyster sauce, 1 teaspoon sesame oil, and 1/4 cup beef broth. This is where all the savory, complex flavors come from!
-
Add sauce and beef:
Pour that gorgeous sauce mixture over the vegetables in the skillet. Give it a quick stir to combine. Then, return your cooked beef to the pan. We’re building layers of flavor here!
-
Thicken the sauce:
Bring the mixture to a gentle simmer. Now, it’s time for the slurry! Gradually stir in the cornstarch and water mixture until the sauce starts to thicken to your desired consistency. It should be glossy and coat the back of a spoon.
-
Add noodles:
Finally, add your cooked lo mein noodles to the skillet. Toss everything together gently but thoroughly, making sure every single noodle and piece of vegetable is coated in that luscious, savory sauce. This is the moment!
-
Serve:
Scoop your beautiful lo mein into bowls. Garnish generously with chopped green onions and a sprinkle of sesame seeds, if you’re using them. Serve immediately and enjoy the fruits of your labor!
Substitutions & Additions
One of the best things about lo mein is how customizable it is! Don’t be afraid to make it your own.
- Veggies: Feeling adventurous? Add mushrooms, water chestnuts, bamboo shoots, bok choy, or even a handful of spinach.
- Protein: No beef? Chicken, pork, shrimp, or even firm tofu would be delicious in this recipe. Just adjust cooking times as needed.
- Noodles: If you can’t find lo mein noodles, ramen noodles (without the seasoning packet), udon noodles, or even good old spaghetti will work.
- Spice: For a little kick, add a pinch of red pepper flakes to the sauce, or a swirl of sriracha when serving.
- Nuts: Toasted cashews or peanuts can add a delightful crunch.
Tips for Success
A few little tricks can make your lo mein experience even better.
- Prep everything first: Stir-frying is fast, so have all your veggies chopped, your garlic minced, and your sauce mixed before you even turn on the stove. This is called “mise en place” and it’s a stir-fry’s best friend.
- Don’t overcrowd the pan: When stir-frying the beef (and even the vegetables), cook in batches if necessary. Overcrowding steams the ingredients instead of searing them, which can make them less tender and flavorful.
- High heat is your friend: For that authentic stir-fry char and quick cooking, make sure your pan is hot!
- Prep ahead: You can chop all your vegetables and marinate the beef up to a day in advance. Cook the noodles ahead of time and toss them with a tiny bit of oil to prevent sticking.
How to Store It
Leftovers are the best, aren’t they? Store any remaining lo mein in an airtight container in the refrigerator. It should keep well for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of water or broth if it seems a bit dry.
FAQs
-
Can I make this vegetarian?
Absolutely! Swap the beef for firm tofu (pressed and cubed) or extra vegetables. Use vegetable broth instead of beef broth. The oyster sauce is fish-based, so you could substitute with a vegetarian stir-fry sauce or more soy sauce and a touch of mushroom powder for umami.
-
My sauce isn’t thick enough, what did I do wrong?
Make sure your slurry (cornstarch and water mixture) was fully incorporated and that the sauce was simmering when you added it. You can always make a little more slurry and add it in, bit by bit, until it reaches your desired thickness. Ensure you’re not adding it to cold liquid, as it won’t thicken properly.
-
How can I get my vegetables crisp-tender?
The key is not to overcook them! Add them in stages if necessary, with harder vegetables like carrots going in first, followed by broccoli and then quicker-cooking ones like snow peas. Stir-frying over medium-high heat for the recommended time should achieve the perfect texture.
