Here’s a quick look at the timeline for this crowd-pleasing and healthy bake.

Ingredients

This healthy casserole uses lean protein and lots of vegetables for a nutritious and flavorful meal.

For the Casserole:

• Lean Ground Turkey or Chicken: 1.5 lbs (93/7 lean is a great choice).
• Onion: 1, chopped.
• Bell Peppers: 2, a mix of colors, chopped.
• Zucchini: 1 medium, chopped.
• Garlic: 3 cloves, minced.
• Red Enchilada Sauce: 1 large (28 oz) can. Look for one with minimal added sugar.
• Black Beans: 1 (15 oz) can, rinsed and drained.
• Corn: 1 (15 oz) can, drained.
• Corn Tortillas: 12, torn or cut into quarters.
• Shredded Monterey Jack or a Mexican Blend Cheese: 1.5 cups.
• Spices: 1 tbsp chili powder, 2 tsp cumin, 1 tsp dried oregano.
• Olive Oil: 1 tbsp.

For Serving (Optional):

• Plain Greek Yogurt or Light Sour Cream
• Diced Avocado
• Fresh Cilantro

The Flavor Architects A Look at the Ingredients

• Ground Turkey: This is our primary healthy swap. Lean ground turkey provides a fantastic, high-protein base that is much lower in saturated fat than ground beef, but still wonderfully savory.
• Lots of Vegetables: The key to a healthy and hearty casserole is loading it up with vegetables. The onions, bell peppers, and zucchini not only add essential nutrients and fiber but also provide texture and natural sweetness.
• Black Beans & Corn: This classic duo makes the casserole more substantial and adds a great boost of plant-based protein and fiber, making every serving more filling and satisfying.
• Greek Yogurt: Used as a topping instead of full-fat sour cream, plain Greek yogurt provides a similar cool and tangy creaminess but with the added benefit of being much higher in protein.
• Corn Tortillas: Using corn tortillas instead of flour tortillas is a great choice for a healthier casserole, as they are typically made with whole grains and are naturally gluten-free.

Cooking Instructions

This wholesome and satisfying casserole is a simple process of layering and baking, making it a perfect recipe for a healthy weeknight dinner.

Step 1: Sauté the Vegetables and Turkey

First, preheat your oven to 375°F (190°C). Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the chopped onion and bell peppers and cook for 5-7 minutes, until they begin to soften.

Add the ground turkey to the skillet and cook, breaking it apart with a spoon, until it is browned and cooked through. Drain off any excess fat from the skillet.

Step 2: Create the Savory Filling

To the skillet with the cooked turkey and peppers, add the chopped zucchini, the minced garlic, and all the dry spices: chili powder, cumin, and oregano. Cook for another 2-3 minutes, stirring constantly, until the zucchini is slightly tender and the spices are very fragrant.

Stir in the rinsed black beans, the drained corn, and about 1 cup of the red enchilada sauce. Let the mixture simmer for a few minutes until everything is heated through and well combined.

Step 3: Assemble the Casserole Layers

Now it’s time to build your healthy casserole. Pour about another cup of the enchilada sauce into the bottom of a 9×13 inch baking dish and spread it around to coat the bottom.

Arrange a single, slightly overlapping layer of the quartered corn tortilla pieces over the sauce. Spoon half of the hearty turkey and vegetable mixture evenly over the tortillas.

Step 4: Finish Layering and Bake

Repeat the layers one more time: arrange the remaining tortilla pieces over the filling, and then top with the rest of the turkey and vegetable mixture. Pour the remaining enchilada sauce all over the top, making sure to cover all the tortillas completely.

Sprinkle the 1.5 cups of shredded cheese evenly over the entire surface. Bake, uncovered, for 30-35 minutes, until the casserole is hot and the sauce is bubbling around the edges. Let it rest for 10 minutes before serving.

Recipe Variations

This versatile and healthy casserole is a perfect template for your own favorite additions.

• Make it Spicy: For a spicy casserole, add ½ to 1 teaspoon of cayenne pepper or a minced chipotle pepper to the filling. Using a “hot” enchilada sauce will also add a good kick.
• Vegetarian Version: To make this a healthy vegetarian casserole, simply omit the ground turkey and add an extra can of beans (like pinto beans) and a cup of sautéed mushrooms for a “meaty” texture.
• Add Some Greens: For an extra boost of nutrients, you can stir a few large handfuls of fresh spinach into the turkey mixture at the very end of the stovetop cooking, right before you start layering.

Serving Suggestions

This is a hearty, all-in-one meal that is perfect served on its own.

• Healthy Toppings: The best way to serve this casserole is with a dollop of plain Greek yogurt (instead of sour cream), a few slices of fresh avocado for healthy fats, and a sprinkle of fresh chopped cilantro.
• Simple Side Salad: A crisp and simple side salad of mixed greens with a zesty lime vinaigrette is a perfect fresh and light accompaniment.
• Cauliflower Rice: For an extra serving of vegetables, you can serve a scoop of this casserole over a bed of warm cauliflower rice.

Storage & Reheating Tips

This casserole is fantastic for meal prep and makes for delicious, healthy leftovers.

• Storage: Let the casserole cool completely. Store leftovers in individual portions or in the baking dish (covered) in the refrigerator for up to 5 days.
• Reheating: Reheat individual portions in the microwave until hot. To reheat a larger portion, place it in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 20-25 minutes, or until heated through.
