Making lite and crunchy taco shells is simple with a few basic ingredients and a baking method that avoids deep-frying. This gives you a crispy, homemade shell with fewer calories and less oil than store-bought or fried versions (link)
PREHEAT OVEN.
Set oven to 375F.
PREPARE TORTILLAS.
Lightly spray both sides...Salt, Chili powder.. If your tortillas are stiff, warm them in the microwave for 20-30 seconds, wrapped in a damp paper towel, to make them more pliable.
SHAPE and BAKE
1) drape over an oven rack. 2) Use a muffin tin.
COOK UNTIL CRISP.
Bake for 10-15 minutes, or until tortillas are golden brown and crisp. Exact time depends on oven and how crispy you want them to be. Keep a close eye on them to prevent burning.
COOL AND SERVE
Remove the shells from the oven and let them cool for a few minutes. They will continue to crisp up as they cool. Serve immediately with favorite fillings.
