Delicious Slow Cooker Mongolian Beef

This recipe is a perfect one to freeze and then throw in the crockpot later. So convenient and the taste is amazing! You’ll definitely want seconds.

With freezer meals, it is easy and time efficient to make more than one meal at a time. I had all the stuff, so I doubled the recipe below to get two bags.

    even my picky eaters begged for 2nds. I added a tiny bit extra garlic and carrots. Added a small pinch of red pepper flakes and 1.5 cups julienned red bell peppers. And gluten free soy sauce, it was awesome!

    At what point are you stopping to move the ingredients to the freezer? You don’t fully cook the meal & then freeze it, do you?

      For this recipe I combine the ingredients for the sauce and put it in the bag, then add the coated raw steak pieces to the bag as well. Freeze. Then thaw and cook later.
