This high protein enchilada casserole is what I make when I want enchiladas without rolling a single tortilla. Shredded rotisserie chicken, black beans, corn, and green chiles get layered with corn tortillas, red enchilada sauce, and sharp cheddar, then baked until the edges bubble. It serves six and it freezes beautifully.
Each serving delivers 54 grams of protein and about 566 calories per serving, calculated from the actual ingredients. That protein number is not an accident. I built the amounts around a pound and a half of chicken so every square hits the dose your muscle actually responds to.
If you don’t know what your own daily protein number should be, take two minutes with my protein calculator before you shop. Most women I coach are surprised how much of the day one square of this casserole covers.
- 54 g protein and about 566 calories per serving, from 1.5 pounds of chicken and a can of black beans across six squares.
- 15 minutes of prep, 25 minutes in the oven, and no rolling.
- Stir yogurt into the sauce. It keeps the layers creamy without a cup of extra cheese.
- Keeps 4 days in the fridge and 3 months in the freezer, baked or unbaked.
- Honest caveat: sauce, beans, and cheese make this a higher sodium dinner, so the FAQ shows how to trim it.
Why This Recipe Works
Here is the thing about protein I tell every client over 35. Your muscle becomes less sensitive to it with each decade. The same 15 grams that built muscle at 25 barely registers at 45. You need a bigger dose per meal, and I aim for 30 grams or more at dinner.
Most casseroles fail that test. They are built on pasta, cheese, and a token amount of meat, so a big serving gives you 15 to 18 grams and a lot of calories. This one flips the ratio. Chicken is the main ingredient, beans back it up, and the cheese is a topping, not the structure.
The other win is decision fatigue. One casserole is six dinners or lunches already decided. When you don’t have to think about what protein is on the plate, you eat enough of it, and holding muscle after 35 mostly comes down to eating enough of it, consistently.
A Few Notes on the Ingredients
Cooked shredded chicken breast: one large rotisserie chicken gives you about 4 to 5 cups of meat, so you may need a bit from a second bird or a quick poached breast to reach 1.5 pounds. Pull the skin off first. Leftover grilled chicken works exactly the same, and so does the chicken from my grilled chicken kabobs if you made extra.
Enchilada sauce: a 20 ounce can or two smaller cans of red sauce. Brands vary a lot in salt and heat, so taste yours. Stirring the Greek yogurt into the sauce before layering is the move that keeps everything creamy without doubling the cheese.
Corn tortillas: they hold their shape in the oven better than flour and add a real corn flavor. Tear them in half to fill the corners of the dish. No need to fry or warm them first, the sauce softens them as it bakes.
Sharp cheddar: a sharper cheese means you use less for the same flavor. Six ounces, shredded from a block, melts better than pre shredded and covers the whole top. Save a little for the last five minutes of baking if you like a browned crust.
Chicken Enchilada Casserole
Ingredients
Equipment
Method
- Heat the oven to 375°F and lightly oil a 9 by 13 inch baking dish. Drain and rinse the black beans well. Thaw the corn and pat it dry. Shred the cheddar and slice the green onions.
- In a medium bowl, whisk the enchilada sauce with the Greek yogurt, cumin, chili powder, and garlic powder until smooth. This is your sauce for every layer.
- In a large bowl, toss the shredded chicken with the black beans, corn, green chiles, and about 1 cup of the sauce until everything is coated.
- Spread 0.5 cup of sauce over the bottom of the dish. Lay 4 tortillas over it, tearing them as needed to cover the bottom. Top with half the chicken mixture and a third of the cheddar.
- Repeat with 4 more tortillas, the remaining chicken mixture, and another third of the cheese. Finish with the last 4 tortillas, the remaining sauce spread to the edges, and the rest of the cheese.
- Cover loosely with foil and bake 15 minutes. Remove the foil and bake 10 minutes more, until the cheese is melted and the edges bubble. The center should read at least 165°F.
- Let the casserole rest 10 minutes so the layers set, then top with cilantro and green onions. Cut into 6 squares and serve with a spoon of Greek yogurt if you like.

- Lower carb: use 8 tortillas instead of 12 and add 2 cups chopped zucchini or cauliflower rice to the chicken layer. You lose some structure, so let it rest 10 minutes before cutting.
- Protein boost: stir 1 cup low fat cottage cheese into the chicken mixture. It melts into the layers and adds a solid dose of protein without tasting like cottage cheese.
- Green version: swap the red sauce for green enchilada sauce and the cheddar for part skim mozzarella for a milder, tangier bake.
- Turkey instead: leftover cooked turkey breast works one for one. This is a great post holiday casserole.
- Lower sodium: use a no salt added enchilada sauce, rinse the beans well, and cut the cheese to 4 ounces. That trims several hundred milligrams per serving.
Storage, Leftovers, and Serving
Cool the casserole, cover, and refrigerate up to 4 days. It actually slices more cleanly on day two. To freeze, wrap individual squares in foil and freeze up to 3 months, or assemble the whole dish unbaked, wrap tightly, and freeze it. Bake from frozen, covered, at 375°F for about 60 minutes, then uncovered for 10.

Reheat single squares in the microwave for 2 to 3 minutes, or in a 350°F oven, covered, for 15 to 20 minutes until hot in the center. The oven keeps the tortilla edges from going gummy.
Serve each square with a spoon of Greek yogurt, sliced green onion, and a simple salad or sauteed peppers on the side. It is one of the easiest meal prep dinners in my high protein recipes collection.

Frequently Asked Questions
Why Is My Enchilada Casserole Watery?
Usually the beans or corn went in wet, or the casserole was cut too soon. Drain and rinse the beans well, thaw and pat the corn dry, and let the baked casserole rest 10 minutes before slicing so the sauce sets. If it still runs, bake it uncovered for the last 10 minutes next time.
Can I Make This Casserole Without Black Beans?
Yes. Pinto beans are the closest swap and taste great with red sauce. If you want no beans at all, add another 0.5 pound of shredded chicken or 1 cup low fat cottage cheese to keep the protein up, and add 1 cup chopped bell pepper for bulk.
Is Chicken Enchilada Casserole Healthy and High in Protein?
This version is. Each serving has 54 g protein, 11 g fiber, and about 566 calories, which is a full dinner dose of protein for most women over 35. The honest caveat is sodium at 1476 mg per serving, because enchilada sauce, canned beans, and cheese all carry salt. A no salt added sauce and a good rinse on the beans bring that down a lot.

Your This-Week Plan
Make this once on Sunday and freeze three of the six squares in foil. Then, on the busiest weeknight you have, pull one out and bake it while you change out of work clothes. The experiment is simple: see whether having a 54 gram dinner already made changes what you reach for at 6 pm. For most of my clients, it does, and that is the whole game.
