What You’ll Need
- Corn tortillas: The base for the tostadas; crisp beautifully when baked.
- Black beans in water: A protein-rich, hearty filling that’s nutritious and delicious.
- Tomato: Adds freshness and a subtle acidity to balance the beans.
- White onion: Provides a mild sweetness and depth of flavour when cooked.
- Ground cumin: A warm, earthy spice that complements the beans.
- Black garlic salt (or regular salt): Enhances savoury flavours.
- Feta cheese: Crumbled on top for creaminess and tanginess.
- Avocado: Adds a buttery texture and richness.
- Spicy salsa (optional): For extra heat and flavour.
Equipment: Baking tray, saucepan, potato masher
How to Make Step-by-Step
- Prepare the tortillas: Preheat the oven to 180°C (350°F). Place tortillas on a baking tray and bake for 20 minutes until crisp and golden brown. Set aside.
- Cook the vegetables: Heat a small amount of oil in a saucepan over medium heat. Add onion, tomato, black garlic salt, and cumin. Sauté for about 5 minutes until softened.
- Add and mash the beans: Drain some liquid from the canned black beans. Add beans to the saucepan and cook until bubbling. Mash with a potato masher until smooth but slightly chunky.
- Assemble the tostadas: Spread mashed beans over each baked tortilla. Top with crumbled feta, avocado slices, and a drizzle of salsa if desired.
- Serve: Arrange on a platter and enjoy immediately with family or friends.
Tips for Making the Best
- Bake tortillas evenly for a crisp texture.
- Use fresh avocado for the best flavour.
- Add a squeeze of lime over the top to brighten the dish.
- Slightly mash the beans for a balance of creaminess and texture.
What to Do and Not to Do
Do:
- Taste and adjust seasoning before serving
- Serve immediately for crisp tostadas
- Customize toppings to your liking
Don’t:
- Overcook the tortillas, or they will become too hard
- Over-mash the beans—they should retain some texture
Storing and Reheating
- Store assembled tostadas in an airtight container in the fridge for up to 24 hours (toppings like avocado are best added fresh).
- Reheat tortillas separately in the oven to maintain crispness.
Recipe Variations
- Swap feta for queso fresco for a more traditional Mexican flavour.
- Add shredded lettuce, radish slices, or pickled jalapeños for extra crunch.
- Use vegan cheese for a plant-based version.
- Top with shredded chicken or beef for a heartier meal.
Interesting Facts
- Tostadas date back centuries in Mexican cuisine and were a way to use leftover tortillas.
- Black beans are high in protein, fibre, and antioxidants, making them a nutritious choice.
- Baking tortillas instead of frying reduces fat content without losing the crunch.
