Meal Prep and Storage Tips

If you’re looking to get ahead, you can prep specific components in advance for easy assembly later on. The mushroom filling and sauteed vegetables can be made a few days in advance and stored in tightly sealed bags in the fridge. The cheese sauce is best made fresh, but you can mix the dry ingredients together until ready to cook.

  • Any leftover assembled cheesesteaks can be stored in the fridge for 3-4 days. For good taste, wrap them tightly in foil or beeswrap before refrigerating.
  • To reheat, place the wrapped sandwiches on a baking sheet and warm in 325°F oven for 10-15 minutes until heated through.
  • You can also freeze these cheesesteaks for longer-term storage. Wrap them individually in foil, then place them in a freezer-safe zip-top bag for 2-3 months. Reheat directly from frozen, adding 5-10 extra minutes in the oven.

With a little meal prep, these vegan cheesesteaks make quick, delicious meals throughout the week. Just assemble, freeze, or refrigerate, and enjoy hot, melty, mushroomy goodness whenever the craving strikes.
