Ingredients
Instructions
1. 1. Prepare Your Oven and Skillet: Preheat your oven to 375 F (190 C). Lightly grease a 9×13-inch baking dish. Heat the olive oil in a large skillet or Dutch oven over medium heat.
2. 2. Brown the Meat and Saute Aromatics: Add the ground turkey or chicken to the hot skillet. Break it up with a spoon and cook until browned, about 5-7 minutes. Drain any excess fat. Add the chopped onion and cook until softened, about 3-4 minutes. Stir in the minced garlic and cook for another minute until fragrant.
3. 3. Combine the Filling Ingredients: Stir in the rinsed and drained black beans, undrained diced tomatoes, enchilada sauce, frozen corn, chili powder, cumin, salt, and black pepper. Bring the mixture to a simmer, then reduce heat and let it cook for 5 minutes, allowing the flavors to meld.
4. 4. Layer the Casserole: Spread half of the meat and bean mixture evenly in the bottom of the prepared baking dish. Arrange half of the corn tortilla strips over the mixture. Sprinkle with half of the shredded cheddar cheese.
5. 5. Add Second Layer: Spoon the remaining meat and bean mixture over the first layer of cheese. Top with the remaining corn tortilla strips and then sprinkle with the remaining shredded cheddar cheese.
6. 6. Bake Until Bubbly and Golden: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly and the casserole is heated through. The edges should be slightly golden.
7. 7. Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the layers to set slightly, making it easier to serve. Garnish with fresh cilantro and a dollop of Greek yogurt or sour cream, if desired.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients for this protein-packed casserole is straightforward, focusing on common pantry staples and fresh items that are easy to find at any grocery store. The beauty of this recipe lies in its simplicity and the ability to create a delicious, wholesome meal without needing exotic or hard-to-find components.
INGREDIENTS:

- 1 tablespoon olive oil
- 1 pound lean ground turkey or chicken
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 (15-ounce) can black beans, rinsed and drained
- 1 (15-ounce) can diced tomatoes, undrained
- 1 (10-ounce) can mild enchilada sauce
- 1 cup frozen corn
- 1 teaspoon chili powder
- 1/2 teaspoon cumin
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 6-8 small corn tortillas, cut into 1-inch strips
- 1 cup shredded cheddar cheese
- 1/2 cup plain Greek yogurt or sour cream (for serving, optional)
- Fresh cilantro, chopped (for garnish, optional)
For simple substitutions, you can easily swap the ground turkey or chicken for lean ground beef. If you don’t have black beans, pinto beans work just as well. Feel free to use fire-roasted diced tomatoes for an extra layer of smoky flavor. For a dairy-free option, use a plant-based shredded cheese alternative and dairy-free sour cream or yogurt. The corn tortillas can be replaced with whole wheat tortillas if preferred, or even gluten-free tortillas to accommodate dietary needs. When it comes to the enchilada sauce, choose your preferred spice level – mild, medium, or hot – to tailor it to your family’s taste.

Easy Variations And Serving Ideas That Fit Real Life
This healthy protein casserole is wonderfully adaptable, making it a staple for any family. For a kid-friendly twist, you can reduce the chili powder slightly or opt for a very mild enchilada sauce. Many kids also enjoy having their own small bowl of toppings to customize their plate, such as extra cheese, a sprinkle of crushed tortilla chips, or a side of guacamole.
Consider adding different vegetables to the mix, such as diced bell peppers, zucchini, or spinach, to boost the nutritional content. For a spicier kick, a pinch of cayenne pepper or a dash of hot sauce can be stirred into the meat mixture. If you want to make it vegetarian, simply omit the ground meat and double up on the beans, adding some sautéed mushrooms or textured vegetable protein (TVP) for extra heartiness.
This casserole is fantastic for a casual family dinner, but it also works well for potlucks or buffet-style gatherings. You can easily double the recipe and bake it in two separate dishes. Serve it with a variety of toppings on the side, such as extra shredded cheese, chopped green onions, sliced jalapeños, salsa, and avocado slices. A simple green salad with a light vinaigrette or a side of steamed rice can round out the meal beautifully. For a heartier side, consider serving it with a side of warm cornbread.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have common pitfalls. Being aware of these can help ensure your healthy protein casserole turns out perfectly every time.
One frequent mistake is overcooking the meat mixture. While you want to brown the ground turkey or chicken, cooking it for too long before adding other ingredients can dry it out. Cook just until no pink remains, then drain any fat promptly.
Another common issue is not draining the canned goods properly. If your black beans aren’t rinsed and drained, they can add excess liquid and a slightly metallic taste to the casserole. Similarly, while the diced tomatoes are used undrained, ensure they are just diced and not overly watery.
Overcrowding the baking dish can lead to uneven cooking and a soggy casserole. If you’re doubling the recipe, use two separate 9×13-inch dishes instead of trying to cram everything into one. This allows for proper heat circulation and even browning.
Not letting the casserole rest after baking is a small but important step often skipped. Cutting into it immediately can cause the layers to fall apart. A 5-minute rest allows the cheese to set and the casserole to firm up, making for cleaner slices and easier serving.
Finally, skimping on seasoning can result in a bland dish. Don’t be afraid to taste the meat mixture before layering (after the meat is fully cooked, of course) and adjust the salt, pepper, chili powder, and cumin to your preference. A little extra flavor makes a big difference.
How To Store It And Make It Ahead Without Ruining Texture
This healthy protein casserole is excellent for meal prepping and storing, making your weeknights even easier.
To store leftovers, allow the casserole to cool completely to room temperature. Cover the baking dish tightly with aluminum foil or transfer individual portions to airtight containers. It will keep well in the refrigerator for up to 3-4 days.
For reheating, individual portions can be warmed in the microwave for 1-2 minutes, or until heated through. If reheating the entire casserole, cover it loosely with foil and bake in a preheated oven at 300°F (150°C) for 20-25 minutes, or until warmed through. You can remove the foil for the last few minutes to crisp up the cheese if desired.
To make ahead, you can assemble the entire casserole up to the point of baking. Cover the un
