If you’re up for enjoying your next Mexican-themed dinner party, then this Mushroom Tostada Recipe is a must-try.

Tostadas, in a nutshell, are baked, toasted, or fried tortillas, similar to tortilla chips, but you’ll get to enjoy them whole instead of cut or broken into pieces.

They’re also naturally gluten-free if you’re using corn tortillas as your base – but double-check the packaging, as some tortillas do contain flour!

This recipe serves 2 – 3 people and makes 6 tostadas.


  • 1 small red onion, quartered and sliced
  • 4 Tbsp white wine vinegar
  • 1 tsp salt
  • 2 tsp sugar
  • 1 large jalapeño, sliced
  • 1 handful of fresh coriander, roughly chopped
  • 1 large avocado, diced
  • 400g portobello mushrooms or 6 medium portabellos
  • 2 Tbsp taco/fajita/Mexican spice mix
  • 6 fresh white or yellow corn tortillas
  • 125ml crème fraîche, for serving
  • 100g feta cheese for serving
  • Lime wedges for serving
  • Salt and pepper, to taste
  • Olive oil (for cooking)

How To Make Mushroom Tostadas – Method

To prep for your baked tostadas:

  1. Place the red onion, vinegar, salt, and sugar in a bowl. Mix to combine and set aside.
  2. Prepare the vegetable toppings.
  3. Preheat the oven to grill.
  4. Brush the tortillas on both sides with a little olive oil.
  5. Place on a baking tray and grill until lightly charred and crisp, turning halfway through to cook both sides.
  6. Season the portabellos with olive oil and taco spice.
  7. Use the same baking tray as the tortillas and grill the mushrooms, turning them halfway through until lightly charred and cooked through (about 5 minutes). Allow to rest, then slice.

To assemble the tostadas:

  1. Spread a dollop of crème fraîche onto the base of each crispy tortilla.
  2. Top with mushrooms, quick pickled onions, avocado, jalapeño slices, and coriander.
  3. Crumble a little feta over the top of each tostada.
  4. Finish each tostada with a squeeze of fresh lime juice just before serving, and enjoy!
