Ingredients
- 2 pounds boneless, skinless chicken thighs (or breasts)
- 2–3 chipotle peppers in adobo sauce plus 2 tablespoons of the sauce
- 1 (14.5 oz / 410g) can canned fire-roasted tomatoes
- 1 medium yellow onion, finely chopped
- 3 cloves garlic, minced
- 1/2 cup (120 ml) chicken broth
- 1 teaspoon dried oregano (Mexican oregano preferred)
- 1 teaspoon cumin
- Salt and pepper to taste
- Juice of 1 fresh lime
- 8–10 crispy corn tostadas (store-bought or homemade)
- Pickled Onions:
- 1 red onion, thinly sliced
- 1/2 cup (120 ml) white vinegar
- 1/2 cup (100 g) granulated sugar
- 1 cup (240 ml) water
- 1 teaspoon salt
- Optional Toppings: crumbled queso fresco, fresh cilantro leaves, sliced avocado, sour cream, hot sauce
Instructions
- In the slow cooker insert, combine chopped onion, minced garlic, chipotle peppers, adobo sauce, fire-roasted tomatoes with juices, chicken broth, oregano, cumin, salt, and pepper. Stir to combine evenly.
- Nestle the chicken thighs (or breasts) into the sauce, making sure they’re mostly submerged. Cover and set the slow cooker to low for 6-8 hours or high for 3-4 hours until chicken is tender and easy to shred.
- While the chicken cooks, whisk together vinegar, sugar, salt, and water in a bowl until sugar dissolves. Add sliced red onions and let soak for at least 30 minutes at room temperature or refrigerate up to 24 hours until pink and mellow.
- Remove cooked chicken from slow cooker and shred with two forks or shredder claws. Return shredded chicken to the sauce and stir to coat well. Squeeze fresh lime juice over the mixture and stir again.
- Lay out crispy tostadas. Spoon a generous amount of chicken tinga onto each tostada. Top with pickled onions, crumbled queso fresco, fresh cilantro, avocado slices, and a drizzle of sour cream or hot sauce if desired.
- Serve immediately to enjoy crispy tostadas and warm chicken.
Notes
If sauce is too watery after cooking, remove chicken and simmer sauce on stove to thicken before shredding. Do not skip fresh lime juice for brightness. Use chicken thighs for juiciness; breasts cook faster and can dry out if overcooked. Assemble tostadas just before serving to keep them crispy. Pickled onions can be made ahead and refrigerated up to 24 hours. For gluten-free, ensure tostadas are corn-based and gluten-free.
