Ultra Simple Tortilla Casserole
This past year we pretty much avoided casseroles. Casseroles tend to be loaded with dairy, which was a big no-go for me and our little boy. But now that I’m out of the woods and he’s getting close, we’re re-discovering our love for all things cheese!
I wasn’t planning on making this chicken tortilla casserole, in fact, it was something I whipped up with ingredients we had on hand. Which means it’s easy and requires minimal ingredients.
Of course, if you want to add things like roasted corn, black beans or green chiles, you totally can! Dress it up, dress it down, no matter what you choose to do, it’s going to be delicious!
Chicken: I prefer using chicken thighs for most of my casseroles, and if I’m being honest, I prefer grabbing a rotisserie chicken and pulling that versus boiling or pressure cooking my own. That’s just the busy/tired mom in me talking.
Enchilada Sauce: I prefer the brand Hatch. They make a variety of sauces and they’re all really good! You can use either red or green enchilada sauce for this recipe.
Tortillas: We like using corn tortillas because they are a little more sturdy than flour tortillas, especially in the case of casseroles. With all the extra liquid, the flour tortillas fall apart more easily than the corn tortillas.
- Can you warm them in the microwave? We recommend warming them in some oil in a pan, but you can always quickly warm them in the microwave. The oil method provides some crisp texture, which is usually hard to obtain in a casserole.
Additions: You can add some additional veggies of your choosing. Here are some suggestions.
- Rinsed black beans
- Roasted corn
- Diced green chiles
- Fire roasted tomatoes
Layering The Casserole
To prepare the filling, you’ll sauté the aromatics in oil, add chicken broth, seasonings, and then simmer the chicken. Pull it off the stovetop and let it rest for a few minutes while you get everything else ready.
LAYERING: Layering the casserole is easy. To start, you’ll want to grease the bottom of the pan with oil to prevent sticking. I like to use avocado oil spray. Then layer as follows:
- Pour in a ¼ cup of enchilada sauce.
- Place 6 tortillas over the enchilada sauce. They will overlap, that’s ok.
- Spread ⅓ cup of the sour cream over top, followed by half of the chicken mixture, ¼ cup of cheese, and a ¼ cup of enchilada sauce.
REPEAT. Repeat by layering six tortillas, spread ⅓ cup of the sour cream over top, followed by the remaining chicken mixture, ¼ cup of cheese, and a ¼ cup of enchilada sauce.
TOP. Layer the remaining 6 tortillas on top, followed by the remaining enchilada sauce and remaining cheese.
Note: you can use whatever cheese you like. I tend to go with colby jack or monterrey jack, but pepper jack or plain cheddar would work too.
GARNISH & BAKE. Sprinkle the sliced green onions over top and cover with foil.
Note: Covering with foil is key! It helps trap moisture inside which prevents it from drying out over time. I like to tent it for half or ¾ of the baking time, then uncover it and continue baking so that the cheese/edges get a little brown but not burnt.
REST & SERVE. After letting the casserole rest, top it with cilantro, slice and serve.
