Lo Mein Meal Prep

There’s a reason meal prep has become so popular, and this beef lo mein recipe is just one reason. It’s a one pan meal you can make in 20 minutes and meal prep for an entire week or lunches or dinners. It’s a healthy, well-balanced meal that’ll make your mouth water!

How to Make Beef Lo Mein Meal Prep

There are just a few steps to make beef lo mein meal prep:

Step 1: Cook Lo Mein Noodles: You’ll want to get the lo mein noodles ready and follow the package directions. If you’re using refrigerated noodles, you don’t need to boil them. One trick is placing the unopened package in hot water to warm up the noodles before use without making them soggy.

Step 2: Marinate Steak Strips:  Slice the beef into thin strips. Then in a medium-sized bowl, mix together 1 tbsp of soy sauce and 1 tbsp of cornstarch. Mix well and then add beef strips for 5-10 minutes. This process is called “velveting”, an Asian secret to getting soft and tender meat.

Note: You can marinate the beef for up to 2 hours. But if you are in a rush, you can skip this process.

Step 3: Make Lo Mein Sauce: Combine soy sauce, hoisin sauce, sugar and ginger in a small bowl. Mix well and set aside.

Step 4: Sauté Beef and Vegetables: Place a large skillet or wok over high heat. Add oil and when it’s hot, add marinated beef. Sauté for 1-2 minutes until no longer pink (no need to be fully cooked), and then add minced garlic, sliced carrots and broccoli. Sauté for 4- 5 minutes until vegetables are tender.

Note: The pan needs to be hot enough before you add the beef. Make sure the beef strips are in a single layer for even cooking.

Step 5: Toss Lo Mein Noodles with Beef and Vegetables: The last step is to add in the lo mein noodles, and then toss everything with the Lo Mein sauce and drizzle with Asian sesame oil. Now you can place into your meal prep containers and you’re good to go!

What is Meal Prep

Meal Prep means planning and preparing meals ahead of time, and putting them into containers to take with you to work/school or for freezing for later on. It’s a game-changer with some awesome benefits:

  • Simplifying: avoiding making decisions at every meal frees your mind to focus on what’s important to you, like a relationship or career 🙂
  • Healthier: you can also more easily resist convenience options like takeout and fast food, and also manage your portions proactively when you’re trying to lose weight 🙂
  • Cheaper: you’ll save a pile of money on restaurant food 🙂
  • Time saving: cooking once for the week will save you time especially as schedules get hectic 🙂

Tips for Selecting Meal Prep Containers

Having a decent set of meal prep containers will help keep your organized, making meal prepping easier and faster. They can also look good!

Most meal prep containers have a rectangular shape and will hold 4-5 cups of food. Here are some tips for selecting them:

  • Brand and size: Buy the same brand and size of containers! Trust me, you don’t want to be sorting through mismatched lids on different types of containers.
  • Quantity: You want to buy a pack of at least 10 containers to have enough ready to be loaded up at any time.
  • Material: Microwaveable, BPA-free plastic containers like these ones are the best lightweight option if you’re always on-the-go. Glass containers like these are a good durable alternative if you want to avoid plastic.
