Ingredients

2–3 lbs boneless, skinless chicken breasts
Provides the protein base that will shred easily after slow cooking.
1 packet taco seasoning
Adds a blend of chili, cumin, and other spices for a classic Tex-Mex profile.
1 tsp garlic powder
Boosts savory, aromatic depth without extra prep.
1 tsp onion powder
Rounds out flavor and complements the fresh diced onion.
1 small onion, diced
Adds sweetness and texture as it cooks down with the chicken.
1 large can red enchilada sauce
The saucy backbone of the casserole that keeps the chicken moist and flavorful.
6 flour tortillas, cut into small pieces
These soften and absorb sauce, acting like a casserole starch for body and mouthfeel.
2–3 cups shredded Mexican blend cheese
Melts into a rich, creamy finish; use 2 cups for a lighter cheese pull or 3 cups for extra cheesiness.

Step-by-Step Instructions

Place chicken breasts in the bottom of the crockpot in a single layer.
Tip: Arrange pieces so they do not overlap much for even cooking.
Sprinkle taco seasoning, garlic powder, and onion powder over the chicken.
Make sure the spices coat both sides for balanced flavor.
Add the diced onion and pour the enchilada sauce over everything, ensuring the chicken is covered.
Press the onion into the sauce so it cooks down and melds with the sauce.
Cook on low for 6 to 8 hours or high for 3 to 4 hours until chicken is cooked through.
The chicken should reach an internal temperature of 165 F and shred easily with two forks.
Shred chicken in the crockpot and stir in tortilla pieces and cheese.
Stir gently to combine so the tortillas begin to absorb sauce and the cheese distributes evenly.
Cover and cook for an additional 30 minutes until cheese is melted and heated through. Serve warm.
Tip: If your crockpot runs hot, check after 20 minutes so cheese does not overcook.
