Ingredients
For the Fajita Chicken
2 pounds boneless, skinless chicken breasts, cut into strips or bite-sized pieces
1 tablespoon olive oil
1 red bell pepper, sliced
1 yellow or orange bell pepper, sliced
1 green bell pepper, sliced
1 medium onion, sliced
2 cloves garlic, minced
Fajita Seasoning
1 teaspoon chili powder
1 teaspoon ground cumin
1 teaspoon paprika
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon dried oregano
½ teaspoon salt, or to taste
¼ teaspoon black pepper
¼ teaspoon cayenne pepper, optional
For the Cheesy Topping
1 cup low-fat cottage cheese
½ cup Greek yogurt
1½ cups shredded mozzarella cheese
½ cup shredded cheddar or Mexican-style cheese
1 tablespoon lime juice
Optional Toppings
Fresh cilantro
Sliced jalapeños
Diced avocado
Salsa
Sour cream or Greek yogurt
Lime wedges
Instructions
1. Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a 9×13-inch baking dish.
2. Season the Chicken
Add the chicken to a large bowl.
Drizzle with olive oil and add the chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, black pepper, and cayenne, if using.
Toss until the chicken is evenly coated.
3. Add the Vegetables
Add the sliced bell peppers, onion, and minced garlic to the bowl with the chicken.
Toss everything together until well coated with the seasoning.
Transfer the mixture to the prepared baking dish and spread it into an even layer.
4. Bake
Bake uncovered for 20–25 minutes, stirring once halfway through.
The chicken should be nearly cooked through and the vegetables should be tender.
5. Prepare the Creamy Protein Cheese Mixture
While the chicken bakes, blend or stir together:
Cottage cheese
Greek yogurt
Lime juice
For the smoothest texture, blend the cottage cheese and Greek yogurt until creamy.
Stir in ½ cup of the mozzarella cheese.
6. Add the Cheesy Topping
Remove the baking dish from the oven.
Spoon the creamy cottage cheese mixture evenly over the chicken and vegetables.
Sprinkle the remaining 1 cup mozzarella and the ½ cup cheddar or Mexican-style cheese over the top.
7. Bake Until Golden
Return the dish to the oven and bake for another 8–10 minutes, until the cheese is melted and bubbly.
For a golden, slightly crispy top, broil for 1–2 minutes. Watch carefully to prevent burning.
The chicken should reach an internal temperature of 165°F (74°C).
8. Serve
Allow the dish to rest for 5 minutes before serving.
Top with fresh cilantro, jalapeños, avocado, salsa, or an extra squeeze of lime.

Cut the chicken into similar-sized pieces for even cooking.
Don’t overcrowd the baking dish.
Drain excess liquid from the vegetables if necessary before adding the cheese topping.
Blend the cottage cheese for a smooth, creamy sauce.
Use freshly shredded cheese for better melting.
Let the dish rest for a few minutes before serving so the creamy topping can set.

Q&A
Can I use chicken thighs instead of chicken breasts?
Yes! Boneless, skinless chicken thighs work well and will be extra juicy, though the protein and fat content may differ.
Can I make this ahead of time?
Yes. Assemble the seasoned chicken and vegetables up to 24 hours ahead and refrigerate. Prepare the creamy cheese topping separately and add it before baking.
How do I store leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3–4 days.
Can I freeze it?
Yes. For best texture, freeze the cooked chicken and vegetables before adding fresh toppings. Freeze in an airtight container for up to 2 months.
How do I reheat it?
Reheat individual portions in the microwave, or warm the dish covered in a 350°F (175°C) oven until heated through.
Can I make it without cottage cheese?
Yes. Replace it with additional Greek yogurt, ricotta, or cream cheese, although the protein content and texture will change.
