how long do you bake a taco shell
1 If you have room on the pan for another tortilla, add another 1/4 teaspoon oil to the water, dip a tortilla, and drape it over the other can. 2  Bake the taco salad shells in a preheated 450 degree F oven until they're lightly brown and firm enough to hold their shape, which will take about 4 to 5 minutes.
