FAQs About Mexican Tostadas

Tostadas can be a very healthy choice, especially when prepared like this recipe. By baking the tortillas instead of frying them and using toppings like fresh vegetables and beans, you get a meal that is low in fat and high in fiber.

The healthiest tostadas are typically those with baked shells, lean protein sources (like beans, grilled chicken, or fish), and plenty of fresh vegetable toppings like lettuce, tomato, and avocado. Avoiding heavy cheese and sour cream also helps keep them light.

A tortilla is a soft, thin flatbread, usually made from corn or wheat. A tostada is a tortilla that has been baked or fried until it becomes firm and crispy, turning it into a flat, crunchy base for various toppings.

Ingredients

Directions

  1. Step 1

    Preheat oven to 400°. Arrange tortillas on 2 baking sheets and toast in oven until crisp, about 5 minutes. Remove from baking sheets.

  2. Step 2

    Lightly spray baking sheets with nonstick cooking spray. Spread beans and onion on one and zucchini and jalapeños on the other. Lightly coat vegetables with cooking spray, season with the black pepper and roast until golden, 12 to 15 minutes.

  3. Step 3

    Transfer half the beans and onion to a bowl with the water and mash beans with the back of a fork until smooth. (Add more water to reach desired consistency, if necessary.) Spread mixture onto tortillas.

Serving & Storage Tips

  • Serve immediately: Tostadas are best enjoyed right after they are assembled to prevent the shells from getting soggy.
  • Storing components: To make ahead, store the baked tortillas in an airtight container at room temperature for up to 2 days. The vegetable and bean topping can be refrigerated for up to 3 days.
  • Reheating: Reheat the topping in the microwave or on the stovetop before assembling on a fresh, crispy tortilla shell.

Ingredient Substitutions

For a non-vegetarian option, top with shredded rotisserie chicken, grilled shrimp, or lean ground turkey.

Pinto beans or fat free refried beans work just as well as black beans. 

 If you like more heat, keep some of the seeds in the jalapeño or add a dash of your favorite hot sauce.

Feel free to use any vegetables you have on hand, such as bell peppers, mushrooms, or spinach.
