Instructions
Preparation Steps
Bring a large pot of salted water to a boil. Cook the penne until al dente according to package directions. Reserve 0.5 cup pasta water, then drain.
While the pasta cooks, pat chicken dry and season with salt, pepper, garlic powder, and Italian seasoning.
Heat olive oil and 1 tablespoon butter in a large skillet over medium-high. Add chicken in a single layer and sear until golden and cooked through, 5 to 7 minutes. Transfer to a plate.
Reduce heat to medium. Add remaining 1 tablespoon butter to the skillet, then stir in minced garlic. Cook until fragrant, about 30 seconds.
Pour in chicken broth and scrape up browned bits. Stir in heavy cream and the cubed cream cheese; whisk until smooth and gently simmering.
Add Parmesan and stir until melted and silky. Stir in crushed red pepper flakes and lemon juice if using. Simmer on low 2 to 3 minutes to thicken.
Return cooked chicken and any juices to the pan. Add drained pasta and toss to coat. Loosen with a splash of reserved pasta water as needed until creamy.
Taste and adjust seasoning. Sprinkle with chopped parsley and serve hot.
Notes
For the best texture, grate Parmesan fresh so it melts smoothly. Reserve pasta water to adjust the sauce to your desired creaminess. Add-ins like baby spinach or steamed broccoli are great. Boneless chicken thighs can replace breasts; cook until 165°F internal temperature. Leftovers reheat well with a splash of milk or broth.
