Ingredients:
- 1 tablespoon olive oil
- 1 large onion, chopped
- 2 cloves garlic, minced
- 1 red bell pepper, chopped
- 1 green bell pepper, chopped
- 1 pound boneless, skinless chicken breasts, cooked and shredded
- 1 (10 ounce) package frozen chopped spinach, thawed and squeezed dry
- 1 (10.75 ounce) can condensed cream of chicken soup
- 1 (10 ounce) can diced tomatoes and green chilies (like Rotel), undrained
- 1 teaspoon chili powder
- 1/2 teaspoon cumin
- 1/4 teaspoon garlic powder
- Salt and pepper to taste
- 12 (6-inch) corn tortillas
- 2 cups shredded Monterey Jack cheese
- 1 cup shredded cheddar cheese
- Optional toppings: sour cream, guacamole, salsa, chopped cilantro
Preparing the Chicken and Vegetables:
- First, let’s get our base flavors going! Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes. You want them to be translucent and starting to get a little golden around the edges.
- Next, add the minced garlic, chopped red bell pepper, and chopped green bell pepper to the skillet. Cook for another 3-5 minutes, stirring occasionally, until the peppers are slightly softened and fragrant. The aroma at this point should be amazing!
- Now, it’s time to incorporate the chicken. Add the cooked and shredded chicken to the skillet with the vegetables. Make sure the chicken is evenly distributed. I usually shred my chicken with two forks it’s the easiest way!
- Add the thawed and squeezed dry spinach to the skillet. It’s crucial to squeeze out as much moisture as possible from the spinach, otherwise, your casserole will be watery. I usually wrap the thawed spinach in a clean kitchen towel and squeeze really hard.
- Pour in the condensed cream of chicken soup and the can of diced tomatoes and green chilies (Rotel). Stir everything together well to combine. The mixture should be nicely coated in the sauce.
- Season the mixture with chili powder, cumin, garlic powder, salt, and pepper. Give it a good stir to ensure the spices are evenly distributed. Taste and adjust the seasonings as needed. I sometimes add a pinch of cayenne pepper for a little extra kick!
- Simmer the mixture for about 5-10 minutes, stirring occasionally, to allow the flavors to meld together. This step is important because it really brings out the best in the spices and allows the sauce to thicken slightly.
Assembling the Casserole:
- Preheat your oven to 350°F (175°C). This is a crucial step, so don’t forget it!
- Lightly grease a 9×13 inch baking dish. This will prevent the casserole from sticking and make it easier to serve.
- Now, we’re going to start layering! Spread a thin layer of the chicken and spinach mixture on the bottom of the prepared baking dish. This will help prevent the tortillas from sticking to the bottom.
- Arrange 4 corn tortillas over the chicken mixture, overlapping them slightly to cover the bottom of the dish. You might need to tear some of the tortillas to fit them properly.
- Sprinkle about 1/3 of the Monterey Jack cheese and 1/3 of the cheddar cheese over the tortillas. Cheese is key to a good casserole!
- Spoon another layer of the chicken and spinach mixture over the cheese.
- Repeat the layers: 4 more corn tortillas, another 1/3 of the Monterey Jack cheese and 1/3 of the cheddar cheese, and the remaining chicken and spinach mixture.
- Top with the final 4 corn tortillas and sprinkle with the remaining Monterey Jack cheese and cheddar cheese. Make sure the cheese is evenly distributed for a beautiful golden-brown topping.
Baking the Casserole:
- Cover the baking dish with aluminum foil. This will prevent the cheese from browning too quickly and ensure that the casserole is heated through.
- Bake in the preheated oven for 20 minutes.
- Remove the foil and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The cheese should be a lovely golden brown color.
- Let the casserole stand for 10-15 minutes before serving. This will allow the casserole to set slightly and make it easier to cut and serve.
Serving Suggestions:
This Chicken Tortilla Spinach Casserole is delicious on its own, but it’s even better with some toppings! Here are a few of my favorite serving suggestions:
- Sour cream: A dollop of sour cream adds a cool and creamy contrast to the savory casserole.
- Guacamole: Fresh guacamole is always a welcome addition to any Mexican-inspired dish.
- Salsa: Choose your favorite salsa, from mild to hot, to add a burst of flavor.
- Chopped cilantro: Fresh cilantro adds a bright and herbaceous note.
Tips and Tricks:
- Make it ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Just add a few extra minutes to the baking time.
- Use different cheeses: Feel free to experiment with different types of cheese, such as pepper jack, Colby jack, or even a Mexican cheese blend.
- Add more vegetables: You can add other vegetables to the casserole, such as corn, black beans, or zucchini.
- Spice it up: If you like a spicier casserole, add a pinch of cayenne pepper or a few dashes of hot sauce to the chicken mixture.
- Use rotisserie chicken: To save time, you can use a rotisserie chicken instead of cooking and shredding your own chicken.
- Prevent soggy tortillas: To prevent the tortillas from becoming too soggy, you can lightly toast them in a dry skillet before assembling the casserole.
Variations:
- Vegetarian version: Omit the chicken and add more vegetables, such as black beans, corn, and zucchini.
- Spicy version: Add a can of diced green chilies or a pinch of cayenne pepper to the chicken mixture.
- Creamy version: Add a cup of sour cream or cream cheese to the chicken mixture.
