Ingredients

• 2–3 lbs boneless, skinless chicken breasts, provides the hearty protein base and shreds easily after slow cooking.
• 1 packet taco seasoning, adds classic taco spice and seasoning without extra measuring.
• 1 tsp garlic powder, gives savory garlic flavor in an easy-to-use powdered form.
• 1 tsp onion powder, boosts onion flavor along with the fresh diced onion.
• 1 small onion, diced, brings sweetness and texture as it cooks into the sauce.
• 1 large can red enchilada sauce, supplies the saucy, tangy base that coats the chicken and tortillas.
• 6 flour tortillas, cut into small pieces, these soften into a casserole-like texture and help thicken the dish.
• 2–3 cups shredded Mexican blend cheese, melts over the top for creamy, salty, cheesy finish.

Step-by-Step Instructions

1. Place the chicken breasts in the crockpot in a single layer. This helps them cook evenly.
2. Sprinkle the taco seasoning, garlic powder, and onion powder over the chicken. Pat the seasonings lightly so they stick.
3. Add the diced onion and the red enchilada sauce, stirring gently to coat the chicken. Make sure sauce covers as much chicken as possible.
4. Cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the chicken reaches 165°F. Use a meat thermometer to confirm doneness.
5. Shred the chicken in the sauce with two forks. Shred directly in the crockpot so the meat soaks up the sauce.
6. Add the flour tortillas pieces and mix well. Stir until the tortilla pieces are evenly distributed and begin to absorb the sauce.
7. Sprinkle the shredded cheese on top, cover, and cook for an additional 10 to 15 minutes until the cheese is melted. If you like browned cheese, transfer to a hot oven for a few minutes, watching closely.
8. Serve hot. Spoon onto plates or into bowls while steaming and enjoy.

Tips, Storage & Variations

• Tips
  • Use 2 lbs for a leaner, less dense casserole or 3 lbs if you want extra chicken and larger portions.
  • Cut tortillas into similar sized pieces so they cook and absorb sauce evenly.
  • If the casserole seems too watery after shredding, remove the lid and cook on high for 15 to 30 minutes to reduce the sauce slightly.
• Storage
  • Refrigerate leftovers in an airtight container for up to 4 days. Reheat gently in the microwave or in a covered skillet until warmed through.
• Freezing
  • Cool completely, then freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Flavor Variations Using Existing Ingredients Only
  • Add extra shredded cheese between layers for a cheesier bake by reserving 1 cup and folding it in before the final melt.
  • Increase the onion for more savory sweetness by using a larger small onion or adding more diced onion.
  • Use the full 3 cups of cheese for a richer, creamier finish or stick to 2 cups for a lighter topping.
