Switch up Taco Night for these Roasted Vegetable Tostadas. Ready in just 30 minutes and packed with plant-based protein and vegetables.

It’s no secret that taco night happens often in my house. Whether it’s my lentil tacos or sofritas tofu tacos, we eat a lot of tacos. And while tacos are king, I wanted to switch things up a bit with vegetable tostadas! Which is basically a crispy taco shell that hasn’t been folded. Piled high with all the toppings, these roasted vegetable tostadas are a must-make.

Why We love these

The inspiration for these tacos came from another of my favorite Mexican-inspired meals, my mushroom fajitas. I love how crispy the edges of the mushrooms get in those fajitas and wanted a similar vegetable experience for these tostadas.

So I grabbed my favorite summer vegetables– corn, zucchini, pepper, and tomato, and roasted them until they were slightly crispy on the outside and tender on the inside. Then I covered crispy tostada shells with refried beans and melted cheese and layered on the roasted vegetables. Finished with a generous dollop of my pico de gallo and guacamole, these vegetable tostadas were ready to eat.

Substitutions and Swaps

I really recommend the fresh ear of corn as I think it makes for the most amazing flavor when roasted. However, if you can only find frozen corn, that works too. This tostada was made for summer vegetables like peppers and zucchini but can easily be adapted for fall and winter. Butternut squash or pumpkin would be great stand-ins for the zucchini, as would Brussels sprouts. Fresh shredded lettuce is also great on these for another vegetable option.

Canned refried beans are an easy option here, but you can substitute refried black beans or smashed beans of your choice.

To make these vegetable tostadas vegan, I recommend using dairy-free cheese for the cheddar. You can also skip the cheese altogether.

I find that the contrast of toasted taco shells with warm beans and vegetables pairs well with fresh pico de gallo and creamy guacamole, but any toppings work. You can swap in any salsa of choice– like my salsa verde, salsa roja, traditional homemade salsa, or a fruity option like my mango salsa.

How to Make Homemade Tostadas

You can either use store-bought tostadas shells or make your own!

You’ll need corn tortillas and cooking spray to make your own tostadas. That’s it!

Start by preheating your oven to 400 degrees F. Spray a baking sheet (or two) with cooking spray and both sides of your corn tortillas. Place the tortillas in a single layer on a prepared baking sheet and lightly season with salt.

Bake for 5 minutes, then flip and bake another 5-8 minutes until crispy and chip-like. Now you are ready to top your tostadas!

Tips for Success

I rely on tostadas from the store and canned refried beans for quick weeknight dinners. You can make your own or use these delicious convenience options.

For even cooking, I recommend chopping the zucchini and pepper in similar sizes so they finish cooking at the same time. If you have selective eaters (hi! me too), then this is a great recipe to serve family style. I make the tostadas with beans and cheese, then put the vegetables and various toppings on the table and let my kids top their tostadas however they’d like.

I often serve these as is, but they are great with rice, grilled corn on the cob or a simple side salad.

      Made this for my family this week and everyone loved it. Can’t wait to make it again! Substituted frozen corn kernels for the fresh because it was what I had on hand.

      Sounds fantastic! There is no better way to amplify the flavors of vegetables than to roast them, so I’m all over this preparation.
