Beef Lo Mein
Beef Lo Mein is one of those recipes that just never lets you down. It’s been in my rotation for years , and every time I make it, I’m reminded why. Savory noodles. Tender beef. Crisp veggies. A sauce that’s just the right amount of salty-sweet with a kick of umami. Whether you're cooking for the first time or the 50th, this one always delivers.

Instructions
Cut lean steak into thin strips
2 lb Lean steak
Mix soy sauce & cornstarch in medium bowl, then add steak & mix well. Marinate for 20 minutes but no more than an hour to tenderize the beef. This step is optional but highly recommended.
4 tbsp Corn starch, 4 tbsp Soy sauce
Begin preparing noodles according to package directions.
8 oz Lo mein noodles
In a separate bowl, mix soy sauce, hoisin sauce, sriracha, brown sugar, ginger root, & sesame oil. Scoop out a tiny bit with a fork to give it a taste, & add whatever else you think might complement that flavor (get creative if you want!)
½ cup Soy sauce, 4 tbsp Hoisin sauce, ¼ cup Sriracha, ½ cup Brown sugar, 1 tbsp Ginger , 1 tbsp Sesame oil
Heat your skillet over high heat, & then add olive oil. Once it is hot & shimmering, add the beef in a single layer. Be careful not to crowd the skillet, & use two pans or do two batches if necessary. Stir fry until the beef is no longer pink. ~3-4 minutes per side. Then, transfer to a plate.
2 tbsp Olive oil
Add the carrots, broccoli, & minced garlic to the empty skillet & stir fry until the vegetables are tender (about 5 minutes).
3 cup Broccoli, 6 oz Carrots, 6 cloves garlic
Combine the beef, noodles, & the sauce with the vegetables in the skillet. Toss together until well combined. Enjoy!

Lo mein is easier to portion when the beef, noodles, and vegetables are thoroughly tossed before they go into containers. Use tongs to lift from the bottom of the pan so the sauce and beef strips do not collect underneath a pile of noodles. Broccoli and matchstick carrots make this a complete batch without a separate vegetable tray, which is part of the appeal of stir-fry meal preps.
Have the sauce mixed and the vegetables ready before the steak hits the pan. The searing stage moves quickly, and stopping to mince garlic is when one part of the meal starts waiting on another. Cook the beef in batches if your pan needs it, then return it with the noodles at the end. For less heat, reduce or omit the sriracha in the sauce rather than changing all the other seasonings. Leave a little bite in the noodles before their final toss in the skillet, since they will soften further in sauce and during reheating. Small broccoli florets can pick up browned edges during their pan stage if they have room. Get that color before the wet noodles and sauce go in, rather than trying to crisp broccoli after everything is tossed.
Noodles can clump as they chill, so add a small splash of water before reheating and loosen them with a fork during the stir. For a refrigerated serving, microwave on high for 90 seconds, stir, then heat for another 45 seconds. Use that as a starting point and continue in short intervals as needed until the food reaches 165°F throughout. Work the sauce back through the noodles instead of adding a large extra pour of soy sauce, which changes the saltiness. If this is your kind of lunch, compare it with the other Asian-inspired meal preps and beef recipes when building your next rotation.
