Here’s Why This Turkey Burrito Casserole Recipe Works
Leftover-friendly: Turn leftover roast turkey into a hearty turkey burrito casserole loaded with Tex-Mex flavors.
No canned soup: This creamy pepper jack cheese sauce is made from scratch, smooth, velvety, and full of real cheese flavor. For even more depth of flavor, make a batch of my red chile sauce.
Layered for flavor: Every bite brings tender flour tortillas, seasoned ground turkey, black beans, green chilies, sweet corn, and melty cheese.
Make once, eat twice: This cheesy baked casserole serves a crowd and reheats beautifully for easy weeknight leftovers.

Recipe Tips
Shred your own cheese: Pre-shredded cheese can make the pepper jack sauce clump and turn waxy. Freshly grated melts smoothly for a creamier casserole.
Warm the tortillas: A quick 10–15 seconds in the microwave softens flour tortillas, making them easier to layer without tearing.
Spray the foil: Lightly oil the side of the foil that touches the casserole to prevent the melted cheese topping from sticking.
Simmer the sauce: Let the homemade pepper jack cheese sauce bubble gently for a few extra minutes so it’s velvety and free of any raw flour taste.
Taste before salting: With salty cheese, canned olives, and green chilies in the mix, you may need little to no extra salt.

Instructions
For the Baked Turkey Casserole:
- Preheat oven to 350 degrees

- In a large skillet, heat the olive oil and add the onion. Cook just until translucent, then add the black beans, corn, chilies, olives, turkey, cilantro, cumin, salt and pepper. Heat through then remove from the heat and reserve while making the cheese sauce.
For The Cheese Sauce:
- In a medium size saucepan set over medium-low heat; add the butter and when it has melted stir in the flour, salt, dry mustard, and pepper. Cook and stir for 1 minute and slowly add the milk, stirring to blend. Cook, stirring continually, until slightly thick and smooth. Reduce heat to low and simmer, stirring, for 3-4 minutes.
- Remove from the heat and add cheese stirring, until the cheese has melted and the sauce is blended, smooth and creamy.
Assemble the Casserole:
- Spread about 1/4 cup of the cheese sauce to the bottom of the prepared casserole dish. Tear about 3 tortillas into pieces and cover with 1/2 cup of the cheese sauce.
- Add 1/3 of the turkey mixture, spreading evenly, then add 1/3 of the grated cheese.
- Repeat the layering 2x and top with the 1 cup of reserved cheese.
- Spray one side of a sheet of foil and cover the dish. Transfer the dish to the oven and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes. Serve with salsa, lime wedges and avocado slices.

We always have turkey for both Thanksgiving and Christmas, too. And the second time around, I start to run out of ideas for leftovers! So thanks for this — such terrific flavor. And I should do as you do — just bag the leftovers and freeze them for a few weeks. Great idea. And terrific recipe — thanks.
Thanks, John…This really is very flavorful and I will definitely make it again. My turkey is gone now but I bet chicken would be delicious too. 🙂
