The Recipe That Replaced Taco Night
If you have ever stood in your kitchen staring down a bag of flour tortillas wondering how to make Mexican food work for the way you are eating, this casserole is the answer. Not a watered-down version. Not a “inspired by” situation. The real thing, just without the carb bomb.
This chicken enchilada casserole is cheesy, saucy, layered, and actually filling. It uses both red and green enchilada sauce, which sounds like a small detail but makes a real difference. You get smokiness from the red and tang from the green. Together they hit different than using one sauce alone.
The base is homemade cottage cheese tortillas. If you have made them before, you already know. If you have not, do not let the name throw you off. They are easy, they hold up great in a casserole, and they add protein without changing the flavor of the dish. You can also use store-bought low-carb tortillas if you are short on time. Both work.
This is the kind of meal that feels like comfort food because it is. It is also the kind of thing that meal preps beautifully, feeds a crowd, and reheats without getting sad. If you are making it for the first time, you are probably going to put it in your regular rotation.
Why This Recipe Works
The double sauce situation is not an accident. Red enchilada sauce brings depth and a smoky quality. Green enchilada sauce is brighter and tangier. Using both gives the casserole a complexity that you would not get from either one on its own. It is the reason this dish tastes like something you ordered from a restaurant instead of something you threw together on a Tuesday.
Rotisserie chicken is the move here. It is already cooked, already seasoned, and it shreds easily. You are not starting from scratch. That matters when you are trying to get dinner on the table in under an hour.
The cottage cheese tortillas act as layers in the casserole the same way regular tortillas would, but they bring protein along with them. They absorb the sauce instead of getting soggy and falling apart, which is exactly what you want in a layered bake. They are also thinner than a corn tortilla, so the casserole is not heavy or dense.
Cheese on top, baked uncovered for the last stretch. That is how you get the golden, slightly crispy layer that makes everyone go back for seconds. The sour cream and green onions at the end are not optional. They finish the dish.
Let’s Talk Ingredients
2 cups cottage cheese (for the tortillas)
This is the base of the homemade tortillas and it does more than you would expect. When blended smooth with eggs and baked, it creates a pliable, protein-rich layer that holds up inside the casserole. Full-fat or low-fat both work. Drain any excess liquid if your cottage cheese seems watery before blending.
4 large eggs (for the tortillas)
The eggs bind the cottage cheese and give the tortillas structure. Without them, the mixture would not set. Make sure you are using large eggs for the right ratio. If you only have medium, use 5.
2 tsp taco seasoning
This seasons the tortillas so they are not bland. Sprinkled on top before baking, it adds flavor right into the layer itself. You can use a store-bought packet or make your own with cumin, garlic powder, onion powder, chili powder, and salt. Either works.
4 cups rotisserie chicken, shredded
The main protein and the reason this casserole comes together quickly. Rotisserie chicken is cooked and seasoned already, so it needs nothing from you except shredding. Pick up a plain or lightly seasoned bird. If you want to cook your own chicken, boneless thighs or breasts both work fine. Thighs are juicier.
1 cup shredded cheese (Monterey Jack, mozzarella, or cheddar blend)
Goes into the layers and on top. Monterey Jack melts smoothly and has a mild flavor that works with the sauces without competing. Cheddar brings a sharper note. Pepper Jack adds heat. Use whatever you have or whatever your household prefers. A blend is also totally fine.
1 1/2 cups green enchilada sauce
The bright, tangy component of the double sauce situation. Green enchilada sauce is made from tomatillos and green chiles and has a completely different flavor profile than red. It balances out the smokiness and adds freshness. Use mild or hot depending on your tolerance.
1 1/2 cups red enchilada sauce
Richer and smokier than the green, this is what anchors the casserole. Red enchilada sauce is made from dried red chiles and has a deeper, earthier flavor. Together with the green it creates that layered, restaurant-quality taste. Again, mild or hot is your call.
1/2 cup sour cream
Spooned on top right before serving. It cuts through the richness of the cheese and sauces and adds a cool, creamy contrast. Do not skip this. It makes the dish. You can use full-fat, light, or Greek yogurt as a swap if needed.
1/2 cup green onions, chopped
Fresh, bright, and a little sharp. They finish the dish and give it color. Scatter them over the sour cream right before you bring the casserole to the table.
How to Meal Prep This Casserole (And Make It Work All Week)
This casserole is one of the better things you can put in your meal prep rotation because it actually holds up in the fridge. A lot of baked dishes get soggy or dry out and lose their appeal by day two. This one does not have that problem. The cottage cheese tortilla layers absorb the sauce as it sits, and the whole thing just gets more flavorful overnight.
You can assemble the casserole up to 24 hours before you plan to bake it. Put it together, cover it tightly with foil, and refrigerate. When you are ready, bake it straight from the fridge. It may need an extra 5 to 10 minutes since it is starting cold.
Once baked and cooled, it stores in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave or put the whole dish back in a 350 degree oven covered with foil until warmed through. If you want to freeze it, bake it first, let it cool completely, and then freeze in portions. Reheat from frozen at 350 degrees until hot in the center.
For meal prep specifically, cut the casserole into squares after it has fully cooled and portion them into individual containers. Pair with cauliflower rice, a simple salad, or roasted veggies and you have lunches covered for most of the week. It packs well and reheats without any fuss.
One more thing: if you want to cut down on active prep time, you can make the cottage cheese tortillas up to two days ahead. Bake them, let them cool, and stack them wi
