Making meats and meat alternatives ahead of time can save valuable meal prep time on taco night. Simply cook your meats per the recipe instructions and let them cool completely before packing them in airtight, freezer-safe containers. Let meats thaw in the fridge and gently reheat them for your taco bar.
Roasted vegetables can be frozen as well. Undercook your vegetables by about five minutes; they will finish cooking when you reheat them. Make sure you cool them completely on paper towels or a separate baking sheet before freezing to avoid accumulating too much moisture and oil which can make veggies soggy.
