Culinary Tips for Tasty Vegetarian Tostadas

Be sure to do all of your chopping and cutting ahead of time (i.e. mise en place)! Once you get cooking, the process moves quickly. The spices can burn if the pan and oil get too hot, so be careful!

If you don’t use low-sodium canned beans, drain and rinse your beans to remove excess salt.

Don’t want to turn your oven on? No problem! You can easily crisp up the tortillas by placing them one at a time on a paper towel or microwave-safe plate, then microwaving for 1 minute on each side. Different microwaves produce different results, so just be sure to watch the first one carefully so it doesn’t burn!

This is a great recipe for kids to help make. They love mashing, mixing, and assembling!

Ingredient Substitutions

  • Corn tortillas: you can use whole wheat tortillas, although they don’t crisp up as well in the oven or microwave. If using whole wheat tortillas, consider simply warming them and making burritos or tacos instead.
  • Vegetables: use all three of our suggestions or just one or two! Or substitute your favorite vegetables, noting that cooking time will vary.
    • Corn: use fresh, frozen, or canned.
    • Red Bell Pepper: substitute orange, yellow, or green. Keep in mind that green peppers aren’t as sweet as red peppers, so this will affect your final product.
    • Zucchini: use yellow squash as an easy replacement.
  • Garlic: use pre-chopped garlic or garlic powder. This will affect the final product’s flavor and nutrition, but it will save you some chopping time.
  • Black Beans: use any beans of your choice! Pinto beans are a good substitution in this recipe. You can also substitute beans cooked from dried. One 15-ounce can contains ~ 1 ½ cups drained beans, so you will need 3 cups total.
  • Salsa: use any salsa of your choice. Fire-roasted and chipotle salsas add smokiness, whereas mango and peach salsas add a touch of sweetness. Choose a spice level that suits your preferences.

Recipe Variations

This black bean and corn tostada recipe can be easily adapted to your taste. Feel free to add more spices, leave some out, or add additional vegetables, such as onions, mushrooms, or potatoes.

This recipe can be simplified by topping with cheese, shredded lettuce, chopped tomatoes, and/or diced avocados – no sautéing required! 

This vegetarian tostadas recipe uses summer veggies, but it can easily be adapted to use seasonal spring or fall vegetables! For a fall variation, use sweet potatoes, mushrooms, butternut squash, kale, onions, and/or cauliflower. For a spring variation, use tomatoes, spinach, peas, turnips, garlic, broccoli, and/or potatoes.

Want to turn these into vegetarian tacos? Simply don’t bake the tortillas! Add all other ingredients as indicated.

Is this a healthy vegetarian tostada recipe?

Absolutely! This plant-based vegetarian tostadas recipe is packed with all of the nutrients needed for a healthy plate and a healthy body. The featured ingredients in this recipe are whole grain corn tortillas, fresh vegetables, and black beans.

Whole Grain Corn Tortillas

Whole grains contain B vitamins, minerals, phytochemicals, and fiber. These nutrients provide your body with energy, promote satiety, and regulate digestion. Avoid varieties with excessive additives; choose corn tortillas with minimal ingredients: corn, water, lime, and salt.

Fresh Vegetables

Red bell peppers, zucchini, and garlic add great color, flavor, nutrition, and texture to this recipe. Red bell peppers are high in Vitamin C, potassium, and lycopene. Zucchini is packed with fiber and water. Garlic contains anti-microbial and anti-cancer properties. (1) Combined, these nutrients contribute to healthy digestion and disease prevention.

Black Beans

Beans of all varieties contain plant-based protein, complex carbohydrates, fiber, vitamins, and minerals and are an important part of a plant-forward diet. These nutrients promote gut health, decrease risk of developing heart disease, cancer, and diabetes, and promote a healthy weight. All of the world’s longest lived populations consume beans daily.

Serving Suggestions for Bean Tostadas

While the veggies are cooking, prepare a variety of garnishes and vegetarian tostada toppings: chopped cilantro, sliced avocado, lime crema, plain Greek yogurt or sour cream, diced tomato, chopped greens, and/or cheese. Once you’re ready to eat these vegetarian tostadas, serve the toppings family-style and let everyone customize their tostadas to THEIR taste!

Storage Tips & Leftover Ideas

Store the sautéed veggies in an airtight container separately from the cooked tortillas, black bean spread, and toppings. Store extra baked tortillas in a bag or container at room temperature. 

There are so many ways to serve leftover ingredients! Make a green salad by combining the cold veggies, a dressing, and other desired garnishes. Alternatively, reheat the veggies and pair with cooked grains, leftover baked tortillas, or fresh tortillas. Leftover black bean spread also makes a great dip for veggies, crackers, or chips or a tasty burrito filling.

Servings 8 tostadas


  • 8 corn tortillas
  • 1 teaspoon + 1 Tablespoon canola oil
  • 1 teaspoon chili powder

  • 1 medium red bell pepper, diced (~1 cup)

  • Once veggies are tender (~10 minutes), add garlic and cook for 30 more seconds. Remove from heat. Add salt and pepper to taste.
  • Build tostadas by spreading a layer of beans on each shell. Top with veggie mixture and desired garnishes. Enjoy!
