Cook pasta in a pot of boiling water according to package directions. Drain water, reserving a 1/4 cup of pasta water for later. Cover pasta to keep warm. Set aside.
Meanwhile, in a large oven-safe skillet, melt the butter over medium-high heat. Once melted, add the chicken pieces. Season chicken with the paprika, garlic powder and fajita seasoning. Stir. Add the onion and both bell peppers. Cook until the peppers are soft, and the chicken is cooked through.
Add the garlic clove to the skillet and cook for 30 seconds. Pour in the chicken broth and heavy cream. Stir and cook until the sauce thickens. Stir in the reserved pasta water and then the cooked pasta. Gently toss to combine everything.
Sprinkle the top evenly with the cheese then place the pan under the broiler until golden and bubbling. (*Watch closely the entire time so it doesn’t burn.) Serve and enjoy!
