What are tostadas?

Tostadas are crisp, flat tortillas used as a base for toppings, and they are a familiar part of Mexican cooking. This version keeps the topping fresh and vegetable-led rather than relying on a cooked filling.

Baking the tortillas makes a sturdy, crunchy base, while lime, coriander and jalapeño bring brightness and a little heat. Creamy avocado rounds out the crisp, juicy vegetables.

Nutrition and macros by portion

The nutrition label shows one serving as written: 180 calories, 3g protein, 22g carbs, 8g fat.

The tortillas provide most of the carbohydrates, while olive oil and avocado contribute much of the fat; the vegetables add freshness and some fibre. To make the plate more substantial, serve a portion with beans for extra protein and substance.

Choosing and preparing the vegetables

Even pieces: Cut the pepper and cucumber into small, similar-sized pieces so they sit neatly on the tortillas. Halve the tomatoes and slice the onion thinly for a mix of juicy and sharp notes.

Jalapeño: Remove the seeds and inner ribs for a gentler flavour, or leave some in if you prefer more heat. Wash your hands after handling it.

Getting the tortillas crisp

Oil: Brush both sides lightly so the tortillas bake evenly without becoming greasy. Arrange them in a single layer on the baking sheet.

Doneness: Start checking at 6 minutes; the tortillas should feel crisp and look lightly golden. They firm up further as they cool, so avoid baking them until deeply browned.

Keeping the topping fresh

Lime and seasoning: Toss the chopped vegetables gently with lime juice, salt and pepper just before assembling. This adds flavour without crushing the tomatoes or making the mixture too wet.

Avocado: Add it after the vegetable topping, as directed, so its soft texture contrasts with the crisp tortilla. A quick squeeze of lime over the avocado can help keep it looking fresh while you serve.

Assembling without losing the crunch

Serve promptly: Put the vegetable topping onto the tortillas shortly before serving, since its juices will soften the crisp base if left to stand. Add only enough topping for each tortilla to remain easy to lift.

Finish: Scatter coriander over the assembled tostadas and serve with lime wedges. Let everyone add more lime at the table if they like.

What to serve alongside

For a fuller meal, serve the tostadas with black beans or refried beans on the side. A simple green salad also works well and keeps the meal fresh.

If serving them as part of a spread, offer extra lime wedges and a bowl of salsa separately. Keeping wet additions on the side helps the tortillas stay crisp.

Recipe notes & tips

• Choose small-to-medium tortillas so they are easy to crisp and top.
• Brush the tortillas lightly and evenly on both sides.
• Check the tortillas from 6 minutes onwards, as oven timing can vary.
• Chop the vegetables before the tortillas finish baking so assembly is quick.
• Keep any extra lime wedges and coriander separate until serving.

Variations

• Milder topping: Remove the jalapeño seeds and ribs before mincing.
• More heat: Leave some jalapeño seeds in the topping.
• Bean side: Serve with black beans or refried beans for a more filling meal.
• Extra crunch: Add finely shredded lettuce just before serving.
• Salsa finish: Serve with salsa on the side so the tortillas stay crisp.

Common mistakes to avoid

• Overbaking the tortillas: Check them from 6 minutes and take them out once crisp and lightly golden.
• Uneven brushing: Coat both sides lightly so the tortillas toast consistently.
• Large vegetable pieces: Chop them finely enough to sit securely on each tortilla.
• Adding the topping too early: Assemble shortly before serving to prevent soggy bases.
• Too much jalapeño heat: Remove the seeds and ribs for a milder result.

How to store

Store leftover vegetable topping and baked tortillas separately in covered containers in the fridge for up to 2 days. Re-crisp the tortillas in the oven and assemble just before eating; add avocado fresh if possible.
