Ingredients

Why this recipe works

The slow cooker works its magic by gently simmering the chicken thighs in the salsa and cheese, allowing the flavors to meld and the meat to become incredibly tender.

The low heat breaks down the collagen in the chicken, resulting in shreddable, juicy pieces that soak up the sauce. The peppers and onions soften but retain a slight bite, adding texture and sweetness to every spoonful.

Using a combination of queso blanco and pepper jack cheese creates a creamy, slightly spicy sauce that coats everything beautifully.

The queso blanco provides a smooth, velvety base, while the pepper jack adds a kick of heat and a gooey, stretchy texture. This dish is a foolproof way to get a restaurant-quality meal on the table with minimal hands-on time.

Notes and substitutions

For the best flavor, choose a good-quality salsa that you enjoy eating on its own. A medium or mild salsa works well, but you can use hot if you like extra heat. If you prefer a chunkier sauce, use a pico de gallo-style salsa. The cheese is the star here, so pick a pepper jack that's nicely spiced and melts well.

You can substitute chicken breasts for the thighs, but be aware they cook faster and can dry out. Check for doneness at the 3-hour mark if using breasts. If you want a thicker sauce, you can stir in a slurry of cornstarch and water after cooking, but the recipe is delicious as is. This dish is naturally gluten-free if you use gluten-free salsa and chips.

• Chicken thighs: Boneless skinless chicken breasts can be used, but reduce cook time to 3 hours on low to avoid dryness.
• Queso blanco dip: Use a store-bought white queso or a homemade white cheese sauce. Avoid aged cheddar as it may separate.
• Pepper jack cheese: Monterey Jack with a pinch of cayenne or red pepper flakes works if you prefer less heat.
• Fresh lime juice: Bottled lime juice is fine, but fresh gives the brightest flavor.
