This easy Chicken Broccoli Alfredo recipe includes golden pan-fried seasoned chicken pieces, tender broccoli, and noodles, all coated in a silky flavor-packed cream sauce for a fantastic weeknight dinner!
Bring a large pot of salted water to a boil. Add the penne and cook until al dente according to package directions. During the last 5 minutes, add the broccoli. Reserve ½ cup of the cooking water, then drain well. Set aside.
Season chicken breasts with the Italian seasoning, salt, and pepper.
Warm the olive oil over medium-high heat in a large nonstick skillet. Once it’s shimmering, swirl the pan to evenly distribute. Add the chicken and leave it undisturbed for 5-7 minutes, until the bottom is golden-brown. Flip over and add in 1 tablespoon of butter between them, picking up the pan to give it a gentle swirl to distribute. Continue cooking for another 5-7 minutes (or until the internal temperature reaches 165°F.)
Transfer the chicken to a cutting board and let it rest for 3 minutes. Cut into small bite-sized pieces. Tent with foil while you prepare the sauce.
In the same pan used to cook the chicken, over medium-low heat, add the butter and cream; whisk until butter has melted.
Add in the minced garlic, garlic powder, Italian seasoning, salt, and pepper; whisk until combined and smooth.
Bring to a gentle simmer (do not boil) and cook for 3-4 minutes, whisking constantly, until it starts to thicken.
Stir in the Parmesan cheese 1/2 cup at a time, stirring, until melted and the sauce is smooth. (If the sauce ends up too thick, only if necessary, add some of the reserved pasta cooking water a few tablespoons at a time, to thin it out.)
Take the sauce off the heat and immediately toss with the cooked penne pasta, broccoli, and chicken pieces.
Divide the mixture among serving bowls. Garnish with parsley, more Parmesan, and black pepper if desired.
