Mexican Bean Tostadas
A tostada is a flat, crisp corn tortilla topped with layers: refried beans at the bottom (they are what keeps the moisture out), then vegetables, cheese and cream. The order isn’t random — it is what stops the base going soggy.

Tostadas are one of Mexico’s easiest and quickest dishes, and the whole idea is contrast: a very crisp base topped with soft, cool things. Layering them in the right order is the difference between a satisfying bite and a soggy one.
Method
-
1
Crisping the tortillas
Brush the tortillas lightly with oil on both sides, arrange them on a tray and bake them at 200°C for 8–10 minutes, turning them halfway, until they are completely hard and crisp. (Or fry them in oil at 170°C for a minute on each side.)

2
The crispness test
A proper tostada snaps when you tap it rather than bending. If it is still flexible, put it back in the oven for 3 more minutes. A flexible base goes soggy the moment you put anything on it.

3
The refried beans
Sauté the onion in oil for 7 minutes, then add the garlic, cumin and paprika for a minute. Add the cooked beans with a little of their liquid and mash them with a fork over medium heat for 8 minutes until they form a thick paste, not a runny one.

4
The secret of the barrier layer
Thick refried beans are the barrier layer. They have to be dry enough not to seep into the tortilla. If they turn out runny, leave them on the heat a little longer until they thicken.

Preparing the toppings
Shred the lettuce finely and drain it well, then dice the tomatoes, sprinkle them with salt and drain them in a sieve for 10 minutes. Draining the water from the vegetables is a step people skip, and it is a major cause of sogginess.

6
Assembling
Spread each tostada with a layer of hot beans, then top with the lettuce, then the tomatoes, then the cheese, cream, avocado and coriander. The order goes from heavy to light and from dry to moist.

Serving
Squeeze lime over the top and serve at once. Tostadas don’t wait — assemble them the moment they will be eaten, and keep the crisp bases in an airtight tin for up to a week.

People also ask
What is the difference between tostadas and tacos?
A taco is a soft tortilla wrapped around the filling. A tostada is a flat, crisp tortilla with the layers piled on top, eaten open. Both use the same tortillas, but the preparation and serving are completely different.
Can I use wheat tortillas instead of corn?
You can, but the result is different — wheat tortillas puff up and end up closer to a thin flatbread, without the same hard crunch. Corn tortillas are traditional, crunchier and closer to the original taste.
Can I add meat or chicken?
Yes — shredded seasoned chicken, minced beef or prawns go straight on top of the beans. Tostadas topped with raw fish marinated in lime (ceviche) are one of the best-known versions on Mexico’s coasts.
The base goes soggy quickly — what’s the fix?
Three things: make sure the tortilla is completely crisp, to the point of snapping; keep the beans thick, not runny; and drain the vegetables. And assemble them at the moment of eating, not minutes before.
