Chicken Broccoli Alfredo Penne is a creamy comfort dish loaded with tender chicken, fresh broccoli, and rich Alfredo sauce all tossed with perfectly cooked penne pasta. This recipe comes together quickly making it ideal for busy weeknights or cozy family dinners when you want something satisfying without spending hours in the kitchen.

I first made this when I needed a quick dinner after work and now my family asks for it regularly because it hits that perfect creamy and savory spot.

Ingredients

  • One pound cooked chicken: any kind works I like thighs for juiciness
  • Twelve ounces gluten free penne: or any pasta shape choose good quality for texture
  • Four tablespoons butter: to build a rich base for the sauce
  • Three quarters teaspoon salt: balances all the flavors
  • Two teaspoons Italian seasoning: for a fragrant herbal note
  • Two teaspoons garlic powder: adds warm depth
  • Two tablespoons finely chopped shallots: for sweetness and complexity
  • Two tablespoons gluten free 1 to 1 flour: to thicken the sauce smoothly
  • Three cups heavy cream: for the rich Alfredo creaminess
  • Half cup chicken broth: for flavor and thinning the sauce if needed
  • Eight ounces shredded Parmesan cheese: gives sharpness and umami
  • One cup diced steamed broccoli: adds freshness and color
  • Optional extra broccoli florets: for more veggie goodness
  • Quarter cup reserved pasta water: to loosen the sauce if it gets too thick
  • Two tablespoons olive oil: for searing the chicken perfectly
  • One and a half teaspoons sweet smoked paprika: brings warmth and subtle smokiness
  • One teaspoon oregano: for earthiness
  • One and a half teaspoons garlic powder: for extra garlicky hit
  • Three quarters teaspoon thyme: for herbal brightness
  • Half teaspoon black pepper: for mild heat
  • Half teaspoon salt: to season the chicken well

Step-by-Step Instructions

Making Seared Chicken:
Season the chicken evenly on both sides with the smoked paprika, oregano, garlic powder, thyme, black pepper, and salt. Heat olive oil in a large skillet over medium heat until shimmering then place chicken in the pan. Sear the chicken for 5 minutes on each side until the exterior is golden and crisp. Lower heat to medium low and cover the pan with a lid, cooking for another 10 to 12 minutes until the internal temperature reaches 165 degrees. Remove the chicken from the pan, let cool a bit, then dice into bite-sized pieces.
Making the Alfredo Sauce:
Allow your frozen broccoli to thaw at room temperature or run under cool water to speed it up. Dice into small pieces for easy eating. Boil pasta in salted water until al dente then drain but save some pasta water. In a large pan, melt butter over medium heat until foaming. Add shallots and the dry seasonings, stirring for about one minute to release flavors. Sprinkle in the flour and stir continuously for about 15 seconds so it cooks and thickens slightly. Slowly pour in heavy cream and chicken broth while stirring constantly to avoid lumps. Let it simmer gently for 5 to 7 minutes until the sauce begins to bubble and thicken. Add in Parmesan cheese and broccoli then mix well until the sauce becomes creamy and the cheese melts completely. Reduce heat to very low then add pasta and diced chicken. Stir well for about one minute to combine everything. If the sauce feels too thick, add a few tablespoons of reserved pasta water to loosen it up. Serve immediately.

Storage Tips

Store leftovers in an airtight container in the refrigerator for 3 to 4 days. Reheat gently in a skillet over low heat or in short bursts in the microwave to avoid breaking the sauce’s texture. Avoid freezing as Alfredo sauces tend to separate and lose their creaminess when thawed.

Ingredient Substitutions

You can swap chicken for shrimp or turkey if preferred. Any pasta shape will work though penne or rigatoni hold the sauce nicely. Instead of heavy cream use a mix of half and half with extra butter for a lighter sauce. If gluten-free flour is not available, all-purpose flour will thicken the sauce just as well.

Serving Suggestions

Pair this dish with a simple green salad dressed with lemon vinaigrette to cut through the richness. Garlic bread or warm crusty rolls make the perfect accompaniment to soak up leftover sauce. A glass of chilled white wine like Chardonnay elevates this meal for a special occasion.

Cultural Background

Alfredo sauce originated in Rome and traditionally was made with butter and Parmesan only. This Americanized version adds cream for extra richness and often includes chicken and vegetables making it a hearty one-dish meal. Broccoli brings a nice green freshness that balances the indulgent sauce.
