Creamy chicken Florentine pasta made in one cast iron skillet. Tender chicken and fresh baby spinach in a rich Parmesan cream sauce, on the table in 30 minutes.
Cook the penne to al dente according to the package directions, then drain and set aside.
Cut each chicken breast in half lengthwise and season both sides with the garlic powder, onion powder, salt, and pepper.
Heat the olive oil in a large cast iron skillet over medium heat. Add the chicken and cook 3 to 5 minutes per side, until it reaches an internal temperature of 165 degrees F. Transfer to a cutting board and let it rest before slicing.
Add the butter and garlic to the skillet and cook 1 minute. Gradually whisk in the flour and cook about 2 minutes, until golden.
Slowly pour in the white wine and cook 1 minute. Whisk in the chicken broth, heavy cream, and Parmesan, then stir in the spinach. Cook until the sauce thickens, then season with salt and pepper.
Add the pasta and sliced chicken and toss everything together to combine. Serve with bread and enjoy.
Notes
Cook then slice. Sear the chicken whole and slice it after a short rest for juicier, more tender meat.
Only simmer the sauce. A hard boil can cause a cream sauce to break, so keep it at a gentle simmer.
Adjust the consistency. If the sauce gets too thick, whisk in a splash of broth. Too thin, simmer a little longer.
Make it gluten-free. Swap the flour for ¼ cup potato starch and skip the browning step.
