Ingredient Selection & Tips
- Bean texture: Use a potato masher or fork to achieve a chunky yet spreadable consistency.
- Avocado: To prevent browning, add lime juice right after slicing or mashing.
- Tortillas: Bake, fry, or use store-bought tostada shells for ease.
- Eggs: Cook your eggs to desired doneness—a runny yolk adds luxurious richness.
Step-by-Step Instructions
1. Prepare the Tostada Shells
- Preheat oven to 350°F (175°C).
- Mix avocado oil and lime juice in a small bowl.
- Brush both sides of corn tortillas with the mixture.
- Sprinkle each tortilla with chili powder and a pinch of salt.
- Place tortillas on a parchment-lined baking sheet, ensuring space between each.
- Bake for 10 minutes, flip, then bake another 7–9 minutes or until crisp and golden.
- Remove and sprinkle with additional salt while hot.
2. Make the Creamy Black Beans
- Heat 1 tbsp avocado oil in a medium pot over medium heat.
- Add 1/4 cup finely chopped white onion and a pinch of salt; cook until soft and translucent (5–7 minutes).
- Stir in 1/2 tsp garlic powder, 1/2 tsp cumin, 1/4 tsp chili powder.
- Add 15 oz can black beans (drained) and 1/3 cup broth. Cover and simmer for 10 minutes, stirring occasionally.
- Uncover, mash beans with a masher or spoon until creamy but textured. If mixture is too runny, cook uncovered for a few minutes, stirring frequently.
- Allow beans to cool slightly to thicken.
3. Prepare Toppings
- In a bowl, mix chopped tomatoes, onion, cilantro, lime juice, and salt to taste for fresh salsa.
- Slice or mash avocado as preferred, adding lime juice and salt.
- Crumble Cotija or feta cheese.
- Chop fresh cilantro leaves.
- Prepare any additional toppings such as pickled onions, lettuce, or crema.
4. Cook Eggs
Heat a nonstick skillet over medium-high heat. Add oil or butter. Crack eggs into pan and cook to preference—sunny-side-up for a runny yolk, scrambled, or poached. Season with salt and pepper.
5. Assemble Tostadas
- Spread a generous layer (about 1/3 cup) of creamy black beans onto each tostada shell.
- Add a layer of mashed or sliced avocado.
- Carefully place a freshly-cooked egg on top.
- Top with tomato salsa, crumbled cheese, cilantro, and any extras.
6. Serve and Enjoy
Carefully transfer tostadas to plates. Garnish with extra lime wedges, hot sauce, and sides like Mexican rice if desired. Enjoy immediately for maximum crunch and freshness.
