⚠️ Watch-outs & how to enjoy it better
The high carbohydrate and fat content can contribute to blood sugar spikes and excess calorie intake if not balanced. The frying process can also add significant sodium and oils. To counteract this, pair tostadas with lean protein (like grilled chicken or beans), plenty of fresh vegetables, and healthy fats (like avocado) to slow digestion and increase satiety. Opt for baked versions when possible and practice portion control.

FAQ
What is the difference between a tostada shell and a tortilla chip?
A tostada shell is a whole, flat, round corn tortilla that has been fried or baked until crisp, designed to hold toppings. A tortilla chip is typically a tortilla that has been cut into wedges before frying, meant for dipping.
Can I make tostada shells at home without frying?
Yes. Brush corn tortillas lightly with oil and bake them at 375°F (190°C) for 10-15 minutes, flipping halfway, until golden and crisp. This reduces the fat content significantly.
Why do my tostada shells get soggy so quickly?
The moisture from toppings (like salsa, beans, or lettuce) quickly softens the crisp shell. To delay sogginess, add wet ingredients just before serving and consider layering a barrier like refried beans or a leaf of lettuce directly on the shell.
