Bring a large pot of well-salted water to a boil. Add rigatoni and cook until just al dente, about 1 minute less than package instructions. Drain and toss with a splash of olive oil to prevent sticking. Set aside.
02 -
Heat olive oil and half the butter in a large skillet over medium-high heat. Season chicken pieces with half the salt, pepper, Italian seasoning, and garlic powder. Add to skillet and cook undisturbed until a golden crust forms, about 3-4 minutes per side. Remove chicken to a plate and reserve juices.
03 -
Reduce heat to medium, add remaining butter to the same skillet. Add minced garlic and sauté until fragrant but not browned, about 30 seconds.
04 -
Pour in chicken broth, scraping browned bits from the pan for flavor. Stir in heavy cream and whisk gently until sauce begins to thicken and becomes velvety, about 3-4 minutes over low heat.
05 -
Lower heat to low. Gradually add cheddar and Parmesan cheese in batches, stirring continuously until fully melted and smooth, resulting in a glossy sauce.
06 -
Add the cooked rigatoni to the skillet with the sauce. Toss gently to coat each piece evenly without breaking the pasta.
07 -
Return seared chicken and any accumulated juices to the pan. Fold gently to warm through and allow flavors to meld without overcooking chicken.
08 -
Turn off heat and let the skillet rest for 1 minute so sauce thickens and binds to pasta. Serve immediately, optionally garnished with extra Parmesan cheese.
