Skinny Taco Casserole Cooking Guide

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for your casserole.
Step 2: Cook the Turkey and Onions
In a large skillet over medium heat, add the lean ground turkey and chopped onion. Cook until the turkey is browned and the onions are translucent, approximately 5-7 minutes. Be sure to break up any large chunks of turkey as it cooks.
Step 3: Season the Mixture
Once the turkey is cooked, stir in the cumin, cayenne pepper, black pepper, and sea salt. Mix well to ensure that the spices are evenly distributed throughout the meat.
Step 4: Add the Salsa
Pour in the salsa and stir to combine. Allow the mixture to simmer for about 2-3 minutes to meld the flavors together.
Step 5: Layer the Casserole
In a 9×13 inch baking dish, spread half of the tortilla pieces across the bottom. Next, layer half of the turkey and salsa mixture over the tortillas. Sprinkle half of the reduced-fat cheddar cheese on top. Repeat this layering process with the remaining tortillas, turkey mixture, and finish with the rest of the cheese.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
Step 7: Add Toppings
Once out of the oven, let the casserole cool slightly. Top it with diced avocado and diced tomato, if desired, for an extra burst of flavor and freshness.
Make It Diet-Friendly

- Substitute ground turkey with ground chicken or a plant-based meat alternative for a different protein source.
- Use low-sodium salsa to reduce sodium intake.
- Skip the cheese entirely or use a dairy-free cheese for a vegan option.
- Add more veggies like bell peppers, zucchini, or spinach to boost the nutritional content and fiber.
Notes on Ingredients
The ingredients used in this Skinny Taco Casserole are not only healthy but also quite versatile. You can easily swap out the reduced-fat cheddar for your favorite cheese or incorporate different types of salsa to change up the flavor profile. For those who prefer more heat, try using a spicy salsa or adding diced jalapeños.
Refrigerate, Freeze, Reheat
The Skinny Taco Casserole is perfect for meal prepping or enjoying leftovers. Here’s how to store it:
- Refrigerate: Store in an airtight container in the fridge for up to 4 days.
- Freeze: Allow the casserole to cool completely, then wrap it tightly in plastic wrap and aluminum foil. It can be frozen for up to 3 months.
- Reheat: To reheat, thaw in the refrigerator overnight if frozen, then bake in the oven at 350°F until heated through, about 20-25 minutes.
Troubleshooting Q&A
What if my casserole is too dry?
If your Skinny Taco Casserole ends up dry, it may be due to over-baking or not enough salsa. Next time, consider adding a bit more salsa or a splash of broth before baking.
Can I make this casserole ahead of time?
Absolutely! You can prepare the casserole in advance, cover it, and store it in the fridge. Just bake it when you’re ready to serve.
How do I know when the casserole is done?
Your casserole is done when the cheese is melted, bubbly, and slightly golden. If you’re unsure, a meat thermometer should read 165°F in the center of the dish.
Can I add more veggies to the casserole?
Yes! Feel free to add additional vegetables like corn, black beans, or bell peppers for added nutrition and flavor. Just be mindful of moisture levels, as too many wet ingredients can make the casserole soggy.
