Holiday leftovers often bring a familiar routine: turkey sandwiches, perhaps a comforting bowl of turkey soup. But sometimes, a creative craving strikes, especially after a feast. This year, fueled by a desire for something different, I whipped up this incredibly hearty, subtly spicy, and remarkably EASY Turkey Enchilada Casserole. It quickly became a new favorite, embodying everything you’d want in a comforting winter meal. And here’s a secret: it’s equally terrific with leftover or rotisserie chicken, making it a versatile dish you’ll want to enjoy all year round!
When I describe this casserole as “spicy,” let me clarify. My husband, who typically shies away from overly hot flavors, not only enjoyed it but went back for seconds! This tells you it’s perfectly balanced, offering just the right amount of warmth and flavor without overwhelming delicate palates. It’s a gentle heat that enhances the rich ingredients, making it appealing to everyone at the table.

The Ultimate Leftover Solution: Turkey OR Chicken Enchilada Casserole
After the festive blur of holiday dinners, many of us find ourselves in a bit of a culinary rut, staring at a refrigerator full of delicious, but familiar, leftovers. While classic turkey sandwiches and my go-to turkey tetrazzini are always appreciated, there’s a unique satisfaction in transforming these familiar ingredients into something entirely new and exciting. This year, a special circumstance led to a wonderful discovery: the Turkey Enchilada Casserole.
We were fortunate to receive a pre-cooked turkey for the holidays, which unexpectedly shifted our Christmas Eve plans. Instead of my usual menu, we enjoyed a delightful turkey dinner with all the traditional fixings. With a whole beef tenderloin already planned for Christmas Day, the generous turkey leftovers were set aside, waiting for a fresh purpose. As a craving for Tex-Mex began to set in, I decided against making my usual chicken enchiladas from scratch. Instead, I saw an opportunity to utilize that beautiful leftover turkey for a super easy and incredibly satisfying enchilada casserole! This revelation means you don’t have to wait for a holiday to enjoy this dish. If a turkey dinner isn’t on your immediate horizon, simply substitute the turkey with leftover shredded chicken, or even a store-bought rotisserie chicken, for a weeknight meal that tastes like it took hours.

Mastering Your Easy Turkey Enchilada Casserole: Essential Tips for Success
One of the best features of this post-holiday dish is the minimal prep work involved. It’s designed to be simple, making it perfect for those times when you want maximum flavor with minimal effort. Whether you’re using leftover turkey or chicken, these tips will help you create a truly exceptional casserole.
- Choosing Your Protein: Plan ahead by setting aside approximately 2 cups of shredded turkey after your holiday dinner. This ensures you have the perfect base for your enchilada casserole. Don’t have turkey? Cooked, shredded chicken is an excellent and equally delicious substitute. For those who prefer a beef option, ground beef works wonderfully too. Simply cook the ground beef with the diced onions, garlic, and bell peppers until browned, then drain any excess grease before proceeding with the recipe. This versatility makes the casserole adaptable to whatever protein you have on hand.
- Year-Round Enjoyment: You absolutely do not need to wait for a holiday to savor this delicious casserole! While it’s a stellar way to utilize turkey, it shines just as brightly with leftover chicken. Even shredded rotisserie chicken offers a fantastic shortcut, bringing this comforting meal to your table any night of the week with even less effort.
- The Secret to Flavorful Sauce: The quality of your enchilada sauce can make or break this casserole. Invest in the best red enchilada sauce you can find. Look for authentic Mexican brands, which often boast a deeper, richer, and more complex flavor profile compared to many mass-produced American brands. If you’re feeling ambitious, a homemade enchilada sauce can elevate this dish to an even higher level, offering unparalleled freshness and spice.
- Customizing Your Casserole with Add-ins: While the base recipe is delicious as is, feel free to personalize it with extra ingredients. I often add diced red bell pepper for a touch of sweetness and color. Other fantastic additions include a small can of chopped green chiles (drained), a can of black beans (rinsed and drained), defrosted frozen corn kernels, or even sliced black olives. These ingredients not only add texture and flavor but also boost the nutritional value, making each bite even more satisfying.
- Selecting the Right Tortillas: The choice of tortillas impacts the casserole’s texture and overall appeal. I typically use tortillas that are a blend of white corn and wheat, which offer a nice balance of pliability and traditional flavor. However, feel free to use your preferred type of tortilla – whether it’s pure corn for a classic taste, or flour for a softer bite. The key is to look for tortillas with approximately a 6-inch diameter, as they layer perfectly in most casserole dishes. If your tortillas feel a bit stiff, a quick warm-up in a dry skillet or microwave can make them more pliable and easier to work with.
- Elevating Presentation and Freshness: If you’re serving this casserole to guests, or simply want to add a vibrant finish for your family, a sprinkle of fresh herbs goes a long way. Fresh oregano, parsley, cilantro, or thinly sliced green onions not only add a beautiful pop of color but also contribute a fresh, aromatic counterpoint to the rich, savory flavors of the casserole. Consider serving with a dollop of sour cream or Greek yogurt, and a side of fresh avocado slices or guacamole for an extra touch of creaminess.

If you’re a fan of Tex-Mex flavors and hearty casseroles, you’ll love exploring other recipes from this culinary family. Consider trying this amazing King Ranch Chicken Casserole for another classic comfort dish, or perhaps this unique Chile Relleno Casserole for a twist on a beloved Mexican staple. To complement your enchilada casserole, a refreshing side like this Fresh Corn and Black Bean Salad would be an excellent choice, adding brightness and texture to your meal.

An easy Tex-Mex casserole that brilliantly utilizes post-holiday turkey leftovers! This recipe is also perfect for using shredded chicken any other time of the year, providing a warm, comforting, and incredibly satisfying meal for the whole family.
Ingredients
- 2 cups shredded leftover turkey (cooked shredded chicken is a perfect alternative)
- ½ cup diced onion
- ¼ cup diced red bell pepper
- 1 tablespoon minced garlic
- 2 tablespoons minced fresh oregano leaves or 2 teaspoons dried oregano
- ½ teaspoon ground cumin
- 1 teaspoon olive oil
- 1 large can red enchilada sauce (or three small 10-ounce cans of good quality enchilada sauce)
- Salt, to taste
- 12 small corn tortillas (approx. 6-inch diameter)
- 2 cups shredded Monterey Jack cheese
Instructions
1. Prepare the Filling: In a large sauté pan, heat the olive oil over medium heat. Add the shredded turkey (or chicken), diced onion, red bell pepper, minced garlic, oregano, and cumin. Cook until the vegetables are softened, about 5-7 minutes. Stir in 1 cup of the enchilada sauce. Taste the mixture and add salt if needed, adjusting to your preference.
2. Prepare Tortillas: While the filling cools slightly, take your corn tortillas and cut each one in half. This makes them easier to layer evenly in the casserole dish.
3. Assemble the Casserole: Preheat your oven to 425°F (220°C). Begin by spreading a thin layer of enchilada sauce on the bottom of a 9×13 inch casserole dish. Layer ¼ of the halved tortillas over the sauce. Next, sprinkle ¼ of the shredded Monterey Jack cheese evenly over the tortillas. Spoon ⅓ of the turkey mixture over the cheese layer, then drizzle with ¼ of the remaining enchilada sauce.
4. Repeat Layers: Repeat these layering steps two more times: tortillas, cheese, turkey mixture, and sauce. Finish the casserole with the remaining tortillas on top, followed by a generous layer of the remaining enchilada sauce, and finally, all of the remaining cheese.
5. Bake to Perfection: Place the casserole in the preheated oven. Bake for approximately 20 minutes, or until the cheese is beautifully melted and bubbly, and the casserole is heated through to the center.
6. Serve: Let the casserole rest for a few minutes before slicing and serving. Garnish with fresh cilantro, green onions, or a dollop of sour cream if desired. Enjoy your delicious and easy enchilada casserole!
Notes
This recipe is highly adaptable. Feel free to substitute shredded chicken for turkey, or even cooked ground beef for a different flavor profile.
Enhance your casserole with additional ingredients: try adding a small can of drained, chopped green chiles, black beans (rinsed and drained), black olives, or frozen corn kernels to the meat mixture for extra flavor and texture.
