Method
Blend the tomato-chipotle sauce
Core and roughly chop 500 g of plum tomatoes. Add 500 g of plum tomatoes, 3 garlic cloves, 30 g of chipotle peppers in adobo, 1 g of dried Mexican oregano, 1.5 g of ground cumin, and 120 ml of unsalted chicken broth to a blender. Blend until mostly smooth, leaving a little natural texture rather than making a completely aerated puree.
Soften the onion
Cut 180 g of white onion into thin slices. Warm 15 ml of olive oil in a wide, deep skillet over medium heat. Add 180 g of white onion and cook, stirring often, until softened and lightly golden at the edges, 5 to 7 minutes. Begin checking at 5 minutes, and lower the heat if the onion begins to brown quickly.
05:00Simmer the chicken safely
Season 570 g of boneless skinless chicken thighs with 3 g of kosher salt and 0.5 g of black pepper, then place it in the skillet with the onion. Pour in the blended sauce and bring it to a gentle simmer. Cover partially and cook over medium-low heat for 18 to 22 minutes, turning the pieces once. Begin checking at 18 minutes, and continue until a food thermometer inserted into the thickest part of each piece reads at least 74°C/165°F. After handling raw chicken, wash your hands and clean any board, utensil, or surface that touched it before preparing the ready-to-eat toppings.
18:00Shred and finish the tinga
Transfer the fully cooked chicken to a clean board and pull it into bite-size shreds with two forks. Return it to the skillet and simmer uncovered for 6 to 8 minutes, stirring occasionally. Begin checking at 6 minutes; the sauce is ready when it looks glossy and clings to the chicken without pooling. Taste and adjust the seasoning only after the sauce has reduced.
06:00Make the black bean spread
Rinse and drain 250 g of no-salt-added black beans, then add them to a small saucepan with 30 ml of fresh lime juice. Warm over medium-low heat while mashing with a fork or potato masher. Cook for 4 to 6 minutes. Use water (optional) only if needed, adding a small splash at a time. Begin checking at 4 minutes; the beans are ready when hot and spreadable but not runny.
04:00Prepare the fresh toppings
Shred 80 g of romaine lettuce into fine ribbons. Slice 120 g of ripe avocado, crumble 40 g of Cotija cheese, and roughly chop 10 g of fresh cilantro. Keep each topping separate so the tostadas can be assembled cleanly and served while the shells are crisp.
Layer and serve the tostadas
Arrange 8 corn tostada shells on a work surface. Spread the warm black beans over each shell, then spoon chicken tinga on top, letting excess sauce drain back into the skillet. Finish with 80 g of romaine lettuce, 120 g of ripe avocado, 40 g of Cotija cheese, 40 ml of Mexican crema, and 10 g of fresh cilantro. Serve immediately with lime wedges (optional).
Smart Substitutions
- Prefer chicken breast? Use the same weight of boneless skinless chicken breast and begin checking the internal temperature after 14 minutes so it does not overcook.
- No Cotija? Use queso fresco for a milder finish or feta for a saltier, sharper crumble.
- No Mexican crema? Thin sour cream with a little lime juice until it drizzles easily.
- No ready-made tostada shells? Brush corn tortillas lightly with oil and bake at 200°C (400°F) for 8 to 12 minutes, turning once, until dry, crisp, and golden before assembling.
Tips and Variations
- Choose ripe, deeply colored plum tomatoes; watery or underripe tomatoes make a thinner, sharper sauce.
- Shred the chicken while it is still hot enough to pull apart easily, then return it to the skillet before the surface dries.
- Keep the bean layer thin and even so it anchors the toppings without making the tostada heavy.
What Went Wrong?
- Tinga is watery Simmer it uncovered over medium-low heat, stirring often, until the sauce coats the chicken and a spoon leaves a brief trail across the skillet.
- Chicken will not shred easily Return it to the sauce and simmer gently for a few more minutes, then check again; thigh meat should separate with light pressure from two forks.
- Tostadas soften too quickly Reduce the tinga until thick, drain each spoonful briefly, and assemble only when every topping is ready to serve.
- Tinga tastes too spicy Use a thinner layer of tinga and add a little more black bean spread, avocado, and crema to each tostada.
