Equipment

  • 1 Potato masher or fork
  • 1 bowl
  • 1 knife
  • 1 cutting board

Ingredients
  

  • 6 tostada shells
  • 2 ripe avocados
  • 2 cups shredded lettuce iceberg or romaine
  • 2 Roma tomatoes diced
  • 2 cups shredded or crumbled cheese Mexican muenster, Chihuahua, queso fresco, or cotija
  • Salt to taste

Instructions
 

  • Gather All Ingredients and Equipment: Before you start preparing the Avocado Tostadas, ensure all ingredients are ready and within reach.
    This includes six tostada shells, two ripe avocados, shredded lettuce, diced Roma tomatoes, shredded or crumbled cheese, and salt.
    Have your potato masher or fork, knife, cutting board, and mixing bowl prepared.
    Gathering everything first makes the process smooth, efficient, and stress-free.
  • Prepare Fresh Vegetables: Wash the shredded lettuce and Roma tomatoes under cold running water to remove dirt and impurities.
    Pat dry with a clean kitchen towel or paper towel to prevent soggy tostadas.
    Shred the lettuce into bite-size pieces if it’s not pre-shredded, and dice the Roma tomatoes into small, even cubes.
    Proper preparation ensures balanced texture and consistent flavor in every bite.
  • Mash the Avocados: Cut each avocado in half lengthwise and carefully remove the pit.
    Use a spoon to scoop the avocado flesh into a medium mixing bowl.
    Using a potato masher or fork, mash the avocado until it becomes creamy.
    Leave small chunks if you prefer texture, or mash thoroughly for a smooth spread.
    Avoid over-mashing to preserve some natural avocado texture.
  • Season the Avocado: Add a pinch of salt to the mashed avocado and gently stir.
    Salt enhances the natural flavor of the avocado and balances the dish.
    For added freshness and to prevent browning, add a squeeze of lime or lemon juice.
    Mix evenly to incorporate the seasoning throughout.
  • Spread Avocado on Tostadas: Take one tostada shell and spread a generous layer of mashed avocado evenly across the surface using the back of a spoon.
    Ensure full coverage so each bite has a creamy base. Repeat this process with all six tostada shells.
    The avocado layer forms the foundation for the tostada, offering richness and moisture.
  • Layer the Fresh Lettuce: Place a layer of shredded lettuce evenly over the avocado spread.
    This adds a crisp texture and freshness to the tostada.
    Distribute the lettuce so each tostada has a uniform layer, ensuring consistency in every bite.
    Lettuce also boosts fiber and nutrient content.
  • Add Juicy Tomatoes: Scatter the diced Roma tomatoes evenly on top of the lettuce layer.
    Tomatoes add natural sweetness and juiciness that complement the creamy avocado.
    Distribute them evenly so every bite contains fresh tomato flavor.
  • Top with Cheese: Sprinkle shredded or crumbled cheese generously over the tomatoes and lettuce.
    Use Mexican muenster, Chihuahua, queso fresco, or cotija cheese for authentic flavor.
    Cheese adds richness, melt, and additional protein.
    Adjust the amount to your taste but aim for a consistent layer across all tostadas.
  • Season and Add Optional Toppings: Lightly sprinkle salt over each tostada to enhance the flavors.
    For extra zest, top with your favorite salsa such as jalapeño salsa, pico de gallo, or salsa verde.
    These additions add layers of flavor and spice.
    Customize the toppings according to your taste preferences.
  • Serve Immediately for Best Flavor: Arrange the prepared tostadas on a serving platter and enjoy right away.
    Tostadas are at their best when fresh and crisp.
    Pair with a side of beans or Mexican red rice for a complete meal.
    These tostadas make a quick, satisfying option for a snack, light lunch, or meatless dinner.

Notes

  • For best flavor and texture, use ripe avocados that yield slightly when pressed. Overripe avocados may become too mushy, while underripe ones lack creaminess.
  • Store-bought tostada shells save time, but homemade shells give a fresher, crunchier result and can be made in minutes by lightly toasting corn tortillas.
  • Feel free to customize toppings — add sliced radishes, cucumber, or a sprinkle of fresh cilantro for extra freshness and texture.
  • Adjust seasoning at the end to your taste, as salt levels can vary depending on your cheese choice.
  • For a heartier meal, add beans, grilled chicken, or shrimp as additional toppings.
