Ingredients and Preparation

Before you start, it helps to gather everything you need. This ensures a smoother cooking experience and reduces the chances of missing a step. Here’s what you’ll need:

Ingredients

• 4 cups shredded chicken (cooked any way you prefer—boiled, baked, grilled, or store-bought rotisserie)
• 1 can (10.5 oz) cream of chicken soup
• 1 can (4 oz) diced green chilies
• 1 cup sour cream (light, regular, or even Greek yogurt)
• ⅔ cup milk (whole milk is preferred for creaminess, but 2% or plant-based milk also works)
• 3 cups shredded sharp cheddar cheese
• 12 corn tortillas
• 1 teaspoon garlic powder
• 2 tablespoons dried chopped onion
• Freshly ground black pepper to taste

Equipment Needed

• 9″×13″ baking dish
• Non-stick cooking spray
• Medium mixing bowl
• Spoon or spatula for mixing and spreading
• Foil for covering the dish while baking
• Knife or kitchen scissors for cutting tortillas

Preparation Steps

1. Cook and shred the chicken if it isn’t pre-cooked. Boiling chicken breasts and shredding them with two forks is a quick and effective method. Alternatively, pulling meat from a store-bought rotisserie chicken can save time.
2. Preheat the oven to 350°F (175°C).
3. Lightly spray a 9×13-inch baking dish with non-stick cooking spray to prevent sticking and make for easier cleanup.
4. In a medium bowl, combine the cream of chicken soup, sour cream, milk, diced green chilies, garlic powder, dried onion, and pepper. Stir until smooth and well blended.
5. Cut 6 of the corn tortillas into quarters (half twice). This makes them easier to layer across the bottom of the dish.

Step-by-Step Instructions

Assembly and Baking

1. Start by lining the bottom of the baking dish with the quartered tortilla pieces from the first 6 tortillas. Try to create a full layer that covers the bottom, even if some pieces overlap slightly.
2. Spread 2 cups of shredded chicken evenly over the tortilla layer.
3. Spoon and spread half of the sour cream mixture on top of the chicken. Use the back of the spoon or a spatula to smooth it out across the surface.
4. Sprinkle half of the shredded cheese over the sour cream layer, distributing it evenly.
5. Repeat the layering process:
   • Cut the remaining 6 tortillas into quarters and place them over the cheese layer.
   • Add the remaining 2 cups of shredded chicken.
   • Pour and spread the rest of the sour cream mixture over the chicken.
   • Finish by topping with the remaining shredded cheese.
6. Cover the dish tightly with foil. This will help the casserole bake evenly and keep the cheese from browning too quickly.
7. Bake in the preheated oven for 40 minutes. The cheese should be fully melted and bubbly, and the casserole heated through.
8. Remove from the oven and let it sit uncovered for 5–10 minutes before slicing. This resting time helps the layers set and makes serving easier.

Beginner Tips and Notes

Even simple recipes come with a learning curve. These tips will help you avoid common pitfalls and make your experience smoother from start to finish.

Cooking the Chicken

You don’t need to overthink the chicken. Boiling is the fastest method—just simmer chicken breasts in salted water for 15–20 minutes, then shred. If you want more flavor, season the water with garlic, onion powder, or bouillon. If you’re in a time crunch, use store-bought rotisserie chicken—just remove the skin and shred the meat.

Sauce Consistency

If your sauce mixture looks too thick, add a splash of milk to loosen it. You want it to be pourable but not watery. The sauce helps keep the tortillas from drying out and binds the layers together.

Tortilla Substitutions

Corn tortillas offer the best flavor and texture for this dish, but you can substitute flour tortillas if necessary. Just be aware that they tend to get softer and may create a more doughy texture in the final dish.

Preventing Over-browning

Keep the casserole covered during baking to avoid burning or over-browning the cheese. If you like a slightly crisp top, remove the foil during the last 5–10 minutes of baking. Keep an eye on it to avoid burning.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, place a portion in the microwave with a damp paper towel over it to retain moisture, or cover and reheat in the oven at 300°F until warmed through.

Freezing Tips

This casserole can be assembled in advance and frozen before baking. Cover tightly with plastic wrap and foil, label with the date, and freeze for up to two months. When ready to bake, thaw overnight in the refrigerator and bake as directed.

Serving Suggestions

A good casserole is filling on its own, but pairing it with a few well-chosen sides can really round out the meal and elevate the experience.

Suggested Sides

• Spanish Rice: Adds a hearty and flavorful side that complements the Mexican-inspired profile.
• Black Beans or Pinto Beans: Serve them whole, refried, or with a bit of cumin and garlic.
• Avocado Slices or Guacamole: The creaminess of avocado balances the richness of the casserole.
• Simple Salad: A crisp green salad with a light lime vinaigrette adds freshness and crunch to the meal.

Sauce Pairings

• Salsa Verde or Pico de Gallo: For those who like a bit of brightness and acidity.
• Hot Sauce: A drizzle of your favorite hot sauce brings in some heat.
• Cilantro-Lime Crema: Mix sour cream with lime juice and chopped cilantro for a cooling drizzle.

Presentation Tips

If you’re serving guests, garnish each slice with a sprinkle of fresh chopped cilantro or green onions for color and a hint of freshness. Serve in squares using a spatula, and offer lime wedges on the side for an optional zing.
