When you’re ready to bake, let them thaw overnight in the fridge. Then place them on a cookie sheet about an inch apart. Bake at 375 until heated through (dependent how frozen they still are). If totally thawed bake for 15-20 minutes. Brush some butter or olive oil on top of the burritos.
If baking from frozen, wrap in tin foil and bake for 30-40 minutes or until heated through.
Serve with any and all fixings!
