Before you start

Before you begin, ensure your shredded turkey is free of any large bones or gristle. Have your baking dish ready on a stable surface and preheat your oven to the required temperature.

Gather all your ingredients and have them measured out so the assembly process remains smooth and efficient. If using refrigerated cheese, let it sit on the counter for a few minutes while you prepare the other components to help it melt more evenly.

Ingredients at a glance (4)
  • 10 count corn tortillas, torn into pieces
  • 3 cups cooked turkey, shredded
  • 2 cups creamy tomato and green chile sauce
  • 2 cups shredded cheddar cheese

Instructions

Base Assembly

  1. Prepare the Base
    Preheat your oven to 375°F (190°C). Take the baking dish and begin by arranging the torn corn tortilla pieces across the bottom to create a solid foundation. Evenly distribute the shredded cooked turkey over the top of the tortillas, ensuring the meat covers the bottom layer completely for a balanced bite in every serving.
    Look for ensure the tortillas are evenly distributed across the base
    Tip If the tortillas are too dry, lightly brush them with a little broth before adding the turkey.

The dish should have a uniform layer of tortillas and turkey at the bottom. Check that the tortillas are torn into roughly even pieces to ensure they cook at the same rate and provide a consistent texture throughout the casserole after it finishes baking in the oven.

Sauce and Topping

  1. Add Sauce and Cheese
    Pour the creamy tomato and green chile sauce over the turkey and tortilla layer. Use a spatula to gently spread the sauce so it reaches all the edges of the dish. Once the sauce is evenly distributed, sprinkle the shredded cheddar cheese generously over the entire surface, ensuring complete coverage for a perfectly browned and melted top layer.
    Look for the sauce should be evenly spread and the cheese should form a thick layer
    Tip Avoid over-mixing the layers to keep the tortilla pieces intact.

The sauce should be spread evenly over the turkey, and the cheese should completely cover the top. Ensure no dry spots remain, as these can burn during baking.

A well-distributed layer of cheese is key to achieving that perfect golden brown finish across the entire dish.

Baking Finish

  1. Bake and Serve
    Place the baking dish in the preheated oven and bake for 30 minutes, or until the sauce is bubbling around the edges and the cheese has turned a deep golden brown. The internal temperature of the turkey should reach 165°F (74°C). Remove from the oven and let it rest for 5 minutes before serving to ensure the structure holds together.
    Look for the edges should be bubbling and the cheese golden
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Checking the center of the dish ensures it is heated through completely.

The casserole should look golden and bubbly. The smell should be savory and inviting. Verify the internal temperature of the turkey has reached 165°F (74°C). Once achieved, remove the dish from the oven and let it rest for five minutes to allow the layers to settle.

Common mistakes

A common mistake is using too much sauce, which can lead to a mushy casserole. Stick to the recommended amount to maintain the right balance between the tortillas and the liquid.

Another error is failing to let the dish rest after baking; allowing it to set for five minutes is essential for getting clean, neat squares when you scoop it out onto serving plates.

How to tell it’s done

The casserole is ready when the cheese on top is melted and bubbling, showing deep golden patches. The sauce should be actively simmering around the edges of the dish.

Ensure the center is hot by inserting a knife; if it comes out hot to the touch, the dish is ready. The internal temperature of the turkey must reach 165°F (74°C) to ensure it is thoroughly heated.

  • Poultry: 165°F (74°C) in the thickest part
