Our family tries for one Mexican dish each week, typically on what we call "Taco Tuesday". Although its not Tuesday, this recipe looked tasty enough to bend the rules. It also allowed for a good portion of the work to be done in advance.
Roasting and pureeing of the vegetables can be done the day or morning before eating. Just refrigerate the puree in an airtight container. You could also add the cut up chicken to the sauce in advance.
The finished product is very pretty, although slightly tricky to eat. I prefer hand held tacos or burritos, or enchiladas needing a fork; but this tostada requires a knife to cut through the tortilla.
The original recipe calls for 1-2 serrano chiles, and it was way too spicy for our 3 yr old... and I only used slightly less than half of one chile. If you're making for children or don't like spice, exclude the serranos completely and spice up your individual tostadas with sliced serranos, salsa, etc.
Chicken Tostadas,
based off of recipe by Epicurious
1 medium white onion
1 pound tomatoes, quartered
2 large garlic cloves
1 or 2 fresh serrano chiles, stemmed
1/2 c. plus 2 tablespoon vegetable oil, divided
3 c. shredded iceberg lettuce
1/2 c. chopped cilantro, divided. Plus more for serving.
1 rotisserie chicken, meat coarsely shredded (4 cups)
6 (6-inch) corn tortillas
1 (1-pound) can refried beans, heated
1 avocado, halved, pitted, and peeled
1/2 c. Mexican crema or sour cream
1/4 c. crumbled queso añjo (aged white cheese, also called cotija). I used Queso Fresco.
1 lime
Accompaniments: sliced serranos; lime wedges
Serve with side of black beans, chips and guacamole and salsa.
Preheat broiler.
Cut half of onion into 3/4-inch wedges, then chop remainder. Toss onion wedges, tomatoes, garlic, and whole chiles with 2 tablespoons oil in a 4-sided sheet pan, spreading in 1 layer.
Broil about 4 inches from heat until softened and charred, 10 to 15 minutes. Meanwhile, toss together lettuce, chopped onion, and half of cilantro.
Purée tomato mixture in a blender along with one or both roasted serranos (to taste) and 1 teaspoon salt until smooth (use caution when blending hot foods). EXCLUDE serranos if you don't want spice. Serrano peppers are spicy! Transfer purée to a bowl and stir in chicken, remaining cilantro, and salt to taste. If you have made puree in advance, heat over low-medium heat on stove and add chicken.
Heat remaining 1/2 cup oil in a heavy medium skillet over medium-high heat until it shimmers. Fry tortillas, 1 at a time, turning once or twice and pressing with tongs to immerse, until golden brown, 45 to 60 seconds per tortilla. Drain briefly on paper towels, then transfer to plates.
Spread tortillas thickly with heated refried beans, then top with chicken mixture. Slice avocado over tostadas and dollop with crema.
Mound lettuce mixture on top and sprinkle with cheese and cilantro. I also squeeze a little fresh lime juice on my tostadas.
