Ingredients in Mini Tuna Tostadas

Let’s take a look at the flavor-packed components that bring these crunchy little bites to life:

Canned Tuna

The protein-packed star of the show. Opt for tuna packed in olive oil for a richer flavor, or go lighter with water-packed—either works beautifully in this fresh, tangy salad.

Mini Tostada Shells

Crispy, bite-sized tostadas give you that satisfying crunch. You can buy them pre-made or toast small corn tortillas in the oven or air fryer until golden and crisp.

Avocado

Creamy, dreamy avocado adds a buttery texture and balances the tangy tuna mixture with mellow richness.

Red Onion

For a sharp, zippy crunch that adds a little bite to every mouthful. Dice it finely so it doesn’t overpower.

Jalapeño (Optional)

If you like a little kick, thinly sliced jalapeño will give these tostadas a spicy pop.

Cilantro

Fresh cilantro adds brightness and that signature herbaceous finish. Don’t skip it unless you’re firmly Team No Cilantro.

Lime Juice

Zesty lime brings all the flavors together and keeps things vibrant and fresh. A must for that classic tostada vibe.

Mayonnaise or Greek Yogurt

A creamy binder for the tuna salad—mayo gives you that classic richness, but Greek yogurt is a great tangy, lighter alternative.

Salt & Pepper

Just enough to make every ingredient shine. A pinch of each goes a long way.

Instructions

Let’s bring these crispy, creamy, flavor-packed tostadas to life in just a few easy steps:

Prep the Tostada Shells

If you’re making your own mini tostadas, cut small corn tortillas into rounds and bake or air fry them at 375°F (190°C) until golden and crisp, about 8–10 minutes.

Make the Tuna Mixture

In a bowl, combine the drained tuna, finely diced red onion, a dollop of mayo or Greek yogurt, a squeeze of fresh lime juice, and a little salt and pepper. Mix until everything’s well combined. Taste and adjust the seasoning or acidity as needed.

Mash the Avocado

In a separate bowl, mash the avocado with a pinch of salt and a dash of lime juice to keep it fresh and vibrant.

Assemble the Tostadas

Spread a thin layer of mashed avocado onto each tostada shell. Top with a generous spoonful of the tuna mixture. Garnish with thinly sliced jalapeño, chopped cilantro, and an extra squeeze of lime if you like.

Serve & Enjoy

Serve immediately so the shells stay nice and crispy! These are best enjoyed fresh, right after assembling.
