How To Heat Tortillas & Taco Shells
I cannot tell you how many times over the years that I’ve overcooked tortillas and taco shells. You’ve got to babysit them!
For Corn or Flour Tortillas: Heat them in a dry skillet for 30 seconds on each side. Or you can grill them. Or you can wrap them in foil and bake at 400° F for 10 minutes. Or you can wrap them in a damp towel and microwave them for 1 minute (this is my least favorite way because they tend to come out chewy).
For Hard Taco Shells: Bake at 350° F for 4 minutes or microwave for 45 seconds (again my least favorite method).
