This is my version of huevos rancheros, which I make for weekend breakfast or brunch when I want to serve something on the filling side. We have breakfast for dinner some weeknights, and this is also perfect for that. Making the bean mash from scratch is the only time-consuming part, but you could save time by using canned beans, or you can make the beans the night before so they’re ready in the morning. Reheat the beans with a bit of warm water to loosen them. I make these with a fried egg, but a poached or scrambled egg would work just as well.
Black Bean Mash
2 cups cooked black beans
1/4 to 1/2 cup light sour cream
2 green onions, white and green parts, chopped
1 teaspoon ground cumin
1/2 teaspoon sea salt
1 teaspoon freshly ground pepper
4 slices cooked bacon, chopped (optional)
8 small corn tortillas
Extra-virgin olive oil, for brushing
1 tablespoon coconut oil or unsalted butter
1 cup shredded white Cheddar cheese
2 avocados, peeled and thinly sliced
1/3 cup chopped fresh cilantro
1 lime, in wedges
Hot sauce, for serving (optional)
Whether cooking the beans from scratch or using canned, drain the beans and add them to a saucepan over low heat and warm through. Add about 1/4 cup tepid water, 1/4 cup of the sour cream, the green onions, cumin, salt, and pepper and mash with a potato masher or a large fork until coarsely mashed but not entirely smooth. Stir in the bacon. Taste for salt and pepper, add the remaining sour cream if you’d like the beans to be creamier, then turn off the heat and keep covered until needed.
Preheat the oven to 400 degrees F. Brush the tops of the tortillas with a bit of olive oil and lay them on a rimmed baking sheet (it’s fine if they overlap). Bake until just lightly browned, 6 to 8 minutes. Remove from the oven and set aside.
Heat a large frying pan with the coconut oil over medium heat. Working in batches as necessary, gently break the eggs in the pan and cook sunny-side up or to your desired doneness, covering the pan if you like your yolks more cooked through. Build a tostada by topping a tortilla with about 1/4 cup of the bean mash, 1 egg, and an eighth of the cheese, avocado slices, and cilantro. Repeat with the remaining ingredients. Serve garnished with a slice of lime and hot sauce to taste.
