Grilled Zucchini and Corn Tostadas Recipe on Love this simple summer recipe! #vegetarian

Earlier this month, I shared a recipe for Zucchini, Corn, and Avocado Salsa and I haven’t stopped eating it. It is a summer staple at our house. I decided to take the same flavors and create an actual meal, Grilled Zucchini and Corn Tostadas. There is nothing wrong with chips and salsa for dinner, but it is nice to mix things up! And now I want to eat these tostadas every night for dinner! They are SO good!

Grilled veggies are my life during the summertime. I love them! I had Josh grill up some zucchini and fresh sweet corn for our tostadas. I love that he doesn’t mind standing out in the hot sun to grill up dinner:)

I made the tostada shells while Josh was manning the grill. I baked flour tortillas to create a crispy tostada shell. You can also use corn tortillas if you need the tostadas to be gluten-free, both are great!

I love baking the tortillas because they are healthier and I don’t have to mess with hot oil! You will never know the tortillas are baked and not fried because they are super crispy and delicious.

  • 6 soft flour tortillas or corn tortillas taco size
  • 3 small zucchini cut in half lengthwise
  • 2 ears sweet corn husked
  • Olive oil for brushing zucchini and corn
  • Salt and black pepper to taste
  • 2 green onions chopped
  • 1/2 cup fresh cilantro chopped
  • 2 ripe avocados pit removed and chopped
  • 2 limes cut into wedges
  • 1/3 cup cotija cheese


  • Preheat oven to 400 degrees F. Spray both sides of the flour tortillas with cooking spray. Sprinkle a little bit of salt on each side of the tortilla. Using a fork, poke little holes all over the tortillas. This will prevent them from puffing up in the oven. Place on a large baking sheet and bake for 4-5 minutes, then turn tortillas over, and bake for 3-5 minutes longer until the tortillas are crisp and light brown. Set aside.
  • Preheat grill to medium-high heat. Brush the zucchini and corn lightly with olive oil. Season with salt and black pepper, to taste. Place zucchini and sweet corn on hot grill and cook until charred and just beginning to soften, about 7-10 minutes. Remove from grill and let cool to room temperature. Chop the zucchini into pieces. With a sharp knife, carefully remove the corn kernels from the grilled sweet corn ears.
  • Top each crisp tortilla with zucchini, corn, green onion, cilantro, and avocado. Squeeze fresh lime juice over the top and garnish with cotija cheese. Serve immediately.

  1. I have seriously been grilling ALL the corn and zucchini…I can’t get enough of it! BUT, I have yet to put it on a tostada. My taste buds thank you! Pinned!

  2. We’ve been grilling so many veggies. I’m going to be super sad when it gets too cold to use the grill around here. Until then, I should be making these! I don’t know why a tostada never crossed my mind…yum!

  3. Love the fresh ingredients in your tostada! I’m a huge tostada fan and I agree that baking the shells is the way to go, rather than messing with oil and all the fat it adds…

  4. This looks delicious! I never thought about baking the tortilla. Thanks so much for that tip. I’m sure it would work well with corn tortillas, right? Pinning this – thanks, again!

  5. I would love this for lunch! And, I haven’t made it here yet to congrat you on Maxwell! He’s beautiful!

  6. sounds delish! But if I’ve got the grill going to cook the veggies, I’m going to heat the tortilla on there too, no reason to turn on the oven on a hot summer day.

  7. My neighbor has been giving me a constant supply of zucchini. I’ll have to try these soon.

  8. I don’t usually comment, but I wanted to let you know we’ve had these for dinner 2-3 times a week for the past month! We LOVE this recipe! Thank you!

  9. We had these last week and I loved them SO…much! The flavor combos are so amazing! Love your recipes every time!

  10. I can’t find cotija cheese in my local grocery. What would be a good substitute? Feta? I’m looking forward to making this if there’s a good substitute!
