*How to turn your corn tortillas into tostadas
If ready-made tostadas aren’t available at your grocery store or local Latin American market, you can easily make tostadas from corn tortillas. Place your corn tortillas in a single layer on a rimmed baking sheet and brush lightly on both sides with a mild vegetable oil. Bake in a 400°F (200°C) oven for 5 minutes, flip the tortillas, and continue to bake until golden and crisp, 5 to 10 minutes more.
