Ingredients
- 1 Tbsp (16g) Olive Oil
- 1 medium White Onion, diced
- 1 Bell Pepper, diced
- 5 oz White Mushrooms, chopped
- 4 cloves Garlic, peeled and minced
- 1 Tbsp Chili Powder
- 1 tsp Cumin
- 1 tsp Smoked Paprika
- 12 oz Shredded Rotisserie Chicken, or any cooked and shredded chicken
- 1 cup (227g) Fat Free Greek Yogurt
- 10 oz can Diced Tomatoes and Green Chilies (such as RO-TEL)
- 12 Extra Thin Corn Tortillas
- 1 1/4 cups (140g) Freshly Shredded Cheddar Cheese
Instructions
- Step 1: Preheat your oven to 350°F (175°C).
- Step 2: Heat a large skillet over medium-high heat and add the olive oil. Sauté the diced onion, chopped mushrooms, and diced bell pepper until the vegetables begin to soften, about 6 to 8 minutes.
- Step 3: Add the minced garlic to the skillet and cook until fragrant, about 30 to 60 seconds. Then stir in the diced tomatoes and green chilies, scraping the bottom of the pan to deglaze and lift any browned bits.
- Step 4: Reduce the heat to low and add the chili powder, cumin, and smoked paprika. Stir well to combine the spices.
- Step 5: Add the shredded chicken and Greek yogurt to the skillet. Fold everything together until well mixed. Remove the skillet from the heat.
- Step 6: Place 6 corn tortillas in the bottom of a 12-inch cast iron skillet or large baking dish to form a base layer.
- Step 7: Spread half of the chicken mixture evenly over the tortillas, then sprinkle half of the shredded cheddar cheese on top.
- Step 8: Layer the remaining 6 tortillas over the cheese, then repeat with the remaining chicken mixture and cheddar cheese.
- Step 9: Bake the casserole in the preheated oven for 25 to 30 minutes, or until the cheese is melted and bubbly and the edges of the tortillas are golden and crispy.
- Step 10: Remove from the oven and top with freshly chopped cilantro, a pinch of salt and pepper, and a dollop of Greek yogurt or sour cream if desired. Serve warm and enjoy!

FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a few hours ahead and keep it covered in the refrigerator until ready to bake. Just add extra baking time if you bake it straight from the fridge.
Can I use flour tortillas instead of corn tortillas?
Yes, flour tortillas work well too, but corn tortillas give the dish its traditional texture and flavor with a bit more crunch when baked.
