Preheat oven to 375°F.

Heat olive oil in a large skillet over medium-high heat. Cook ground meat with fajita seasoning, smoked paprika, salt, and pepper until browned and cooked through, about 6-8 minutes. Break up any large pieces as it cooks.

In the skillet, combine browned meat, uncooked pasta, sliced peppers, onion, minced garlic, bone broth, salsa, and blended cottage cheese. Stir everything together until well combined and pasta is evenly distributed.

Cover with lid and bake for 25–30 minutes, stirring halfway through to ensure even cooking and prevent sticking.

Remove foil, sprinkle with cheddar cheese, and bake uncovered another 8–10 minutes until cheese is melted and bubbly, and pasta is tender.

Let stand for 5 minutes before serving to allow the sauce to thicken slightly and make serving easier.
