1Boil pasta in a large pot according to package directions for al dente. Reserve 1/4 cup of pasta water.
2In a small bowl, mix together sweet smoked paprika, oregano, garlic powder, thyme, black pepper, and 1/2 teaspoon salt.
3Pound chicken breasts to thin them slightly. Season both sides with the prepared seasoning mix.
4Heat olive oil in a large skillet over medium heat. Sear chicken breasts for 5 minutes on each side.
5Lower heat to medium-low, cover the skillet, and cook chicken for an additional 10-12 minutes, until internal temperature reaches 165°F (74°C). Remove chicken and set aside.
6Add butter to the same skillet and let it melt. Add dry shallots and Italian seasoning, stir and simmer for 1 minute.
7Add gluten free flour and stir well, scraping the bottom of the pan.
8Pour in chicken broth and heavy cream. Whisk until a creamy sauce forms.
9Add shredded Parmesan cheese and stir until melted and sauce thickens.
10Add cooked pasta to the sauce and toss to coat evenly. Add reserved pasta water, one tablespoon at a time, to thin the sauce as needed.
11Slice the cooked chicken breasts and add them to the pasta. Stir gently to combine.
