Description

Ever since the epic 90s-style tostadas of my childhood, tostadas have been one of my all-time favorite weeknight dinners. These Black Bean Tostadas are fueling my tostada obsession as of late. They’re quick & easy to prepare, but they’re seriously so satisfying. 

What separates a great tostada from a good or just-fine tostada, in my experience, are a few different toppings that create layers of flavor & texture. That’s exactly what happens here; they come together with 3 easy-to-prepare components:

  1. Refried black beans. Start with canned beans for quickness & ease (though if you want to go the extra mile & cook beans from scratch, YUM!), then quickly simmer them with flavorful aromatics & spices. 
  2. Charred sweet corn. Use the burner on a gas stove to quickly char up some sweet corn, or go ahead & toss it under the broiler. The corn provides the perfect crunchy pop of texture, & charring it brings out a slightly nutty flavor. 
  3. Avocado crema. Easy to prepare in a food processor, this crema is eat-straight-off-the-spoon good, & it provides amazing cooling creaminess to the tostadas. (Check the Recipe Notes, below, for an easy vegan alternative!)

Layer them up & finish them off with any other tostada toppings your heart desires – check out the blog post, above, for plenty of inspiration to get you started!

Instructions

Prep note: Once you begin cooking, these black bean tostadas come together very quickly. It’s really helpful to get any chopping &  measuring done ahead of time, placing everything within an arm’s reach of the stovetop.

  1. Prep the avocado crema: Add all listed ingredients (minus the water) to a food processor, seasoning with a heaping ½ teaspoon kosher salt & ground black pepper as desired. Pulse to break up the avocado & cilantro, then blend until smooth & creamy. If necessary, add a couple tablespoons water to smooth out texture. Set aside, or store in an airtight container in the refrigerator for up to 2 days.A small ceramic bowl filled with avocado crema sits atop a white and gray marble surface surrounded by avocado halves, discarded lime halves, loose fresh cilantro leaves, and a small wood pinch bowl filled with kosher salt.
  2. Char the sweet corn: Place the sweet corn directly over a gas burner. Light to a medium-high flame & cook about 2 minutes per side or until as charred as desired. Transfer to a cutting board & carefully slice kernels away from the cob. Set aside. (If you do not have a gas stove, you can also char the corn on an outdoor grill, in a grill pan, or under the broiler.)Two ears of charred sweet corn sit atop a white ceramic plate that rests atop a gray and white marble surface. A pair of grilling tongs rests atop the white plate.
  3. Sauté the aromatics: Meanwhile, as the corn chars, get the black bean tostada topping cooking. Add the olive oil to a medium skillet over medium heat. Once hot & shimmering, add the onion. Season with 1 teaspoon kosher salt. Cook, stirring occasionally, until translucent & fragrant, 3-4 minutes. Stir in the garlic. Cook just until fragrant, about 30 seconds. Add in the chili powder, ground cumin, & smoked paprika. Stir, coating the onion. Cook 1-2 minutes longer, until very fragrant.Onion, garlic, chili powder, ground cumin, and smoked paprika saute in a white double handle braiser that sits atop a gray and white marble surface. A wooden spatula rests inside of the braiser for stirring and the braiser is surrounded by a small wooden pinch bowl and opened jars of spices.
  4. Make the black bean tostada topping: Add the black beans to the skillet, stirring to combine with the aromatics. Cook, stirring occasionally, until warm, 1-2 minutes. Add the vegetable broth/water & increase heat to bring the black bean mixture to a simmer. Use a spatula or wooden spoon to mash the black beans slightly, binding everything together. If needed, cook 1-2 minutes longer to thicken slightly. Squeeze the lime juice over the black bean mixture. Taste & season with additional kosher salt & ground black pepper as desired. Remove from the heat & set aside for tostada assembly.Black bean tostadas filling fills the inside of a white double handle braiser that sits atop a gray and white marble surface. The braiser is surrounded by a small wood pinch bowl filled with kosher salt, a small ceramic pinch bowl filled with ground black pepper and half of a discafded lime. Another half of a discarded lime and a wooden spatula rest atop the black bean tostada filling.
  5. Assemble black bean tostadas: If desired, warm tostada shells according to package directions. Spread the prepared black bean topping over each tostada shell. Top with charred sweet corn kernels & a drizzling of avocado crema over top. If desired, add other toppings like chopped cilantro, cotija cheese, shredded lettuce, etc. Enjoy!A close up of assembled black bean tostadas surrounded by bowls of toppings and fresh lime wedges.

Notes

  • Vegetarian & vegan black bean tostadas: As written, the black bean tostada topping is completely vegan, though the avocado crema is not. For a completely vegan dish, feel free to swap the sour cream/yogurt in the crema with your favorite dairy-free alternative or try this vegan cashew crema instead.
  • Storage & Reheating: Once assembled, these black bean tostadas are best enjoyed immediately. The black bean tostada topping, however, will keep, stored in an airtight container in the refrigerator for up to 5 days. Simply reheat on the stovetop or in the microwave until warmed through & assemble tostadas as desired.
  • 15-Minute Meal Prep: Nearly all of the active prep work for these black bean tostadas comes from prepping the avocado crema & chopping the veggies. Prep either or both in advance for a great head start on your tostadas dinner – it takes 15 minutes, tops:
    • Dice 1 small yellow onion. Store in an airtight container in the refrigerator for up to 5 days (<5 minutes active prep).
    • Prep the avocado crema according to Step 1 of Recipe Directions, above, & store in an airtight container in the refrigerator for up to 2 days. (10 minutes active prep)
