Chicken Alfredo Bake is a creamy, cheesy pasta dinner made with penne, tender seasoned chicken, homemade Alfredo sauce, and Italian cheese. The chicken can be marinated in Italian dressing for even more flavor, then sliced, cooked, and baked with pasta until bubbly and golden.
We love this for family dinners, Sunday meals, potlucks, and feeding a crowd because it bakes in a 9×13 pan and feels hearty without being hard. Serve it with salad, Garlic Bread, Breadsticks, or Roasted Vegetables for a dinner everyone will be excited about.
Why you’ll love it + Why it works:
- Perfect for Busy Nights: Assemble it ahead of time and let the oven finish dinner.
- Feeds a Crowd: A 9×13-inch pan is perfect for family dinners, potlucks, or sharing with friends.
- Comfort Food Classic: Every bite is loaded with creamy sauce, pasta, and melty cheese.
- Homemade Alfredo Sauce: The buttery garlic sauce is rich, smooth, and much more flavorful than jarred sauce.
Chicken Alfredo Bake Ingredients
- Penne pasta (1 (12-ounce) package): Holds the creamy Alfredo sauce inside and out, making every bite flavorful. Rotini or ziti also work well.
- Boneless skinless chicken breasts (3, marinated in Italian dressing if desired): Adds hearty protein and stay tender when marinated before cooking. Chicken thighs can also be substituted.
- Vegetable oil: Helps cook the chicken evenly without sticking to the pan.
- Thyme (¼ teaspoon): Adds subtle earthy flavor that complements the creamy sauce.
- Poultry seasoning (¼ teaspoon): Boosts the flavor of the chicken with a simple blend of herbs.
- Salt and pepper (to taste): Seasons both the chicken and the finished casserole.
- Olive oil (2 tablespoons): Helps cook the chicken while adding a little extra flavor.
- Butter (½ cup): Forms the rich base of the homemade Alfredo sauce.
- Minced garlic (2 teaspoons): Adds classic savory flavor to the Alfredo sauce. Fresh garlic gives the best flavor.
- All-purpose flour (4 tablespoons): Thickens the sauce into a creamy consistency.
- Half and half (3 cups): Creates a rich, velvety Alfredo sauce without being overly heavy.
- Milk (3 cups): Balances the richness of the sauce while keeping it smooth and creamy.
- Kraft Italian Five Cheese Blend (3 cups, divided): Melts into the sauce and creates a golden, cheesy topping. Freshly shredded cheese also works well.
- Italian seasoning (garnish): Adds a pop of color and extra herb flavor before serving.
How to Make Chicken Alfredo Bake
OPTIONAL MARINADE. If time allows, marinate the chicken. Add chicken and Italian dressing to a bag. Let it sit overnight or even for a few hours to make the chicken tender and full of flavor.
PASTA. Cook pasta as directed. Drain and set aside.
While pasta is cooking, heat 1-2 tablespoons of oil in a skillet on medium heat.
CHICKEN. Slice your (marinated) chicken in half so they are thinner pieces. This will help them cook through evenly.
In a bowl, mix salt, pepper, thyme, and poultry seasoning. Rub it on all sides of your chicken breasts.
Add chicken to hot oil and cook on both sides until done (about 15-20 minutes).
Remove to a plate to let cool.
SAUCE. While the chicken is cooling, preheat your oven to 350°F and start on your sauce. In a separate large skillet, melt the butter; add garlic and cook for 1-2 minutes.
Using a wire whisk, mix in flour and stir until bubbly.
Mix in half & half and milk (you can also sub these two for heavy cream), and stir to combine. Bring to a boil and then reduce to low heat and simmer for minutes.
With your whisk, mix in 1½ cups of cheese. Cook for an additional 5 minutes until the sauce starts to thicken.
Remove sauce from heat.
ASSEMBLE. Cut your cooked chicken into bite-size pieces and add to a large bowl. Add the pasta to your bowl and then the sauce. Mix everything to combine.
BAKE. Spray a 9×13 baking dish with nonstick spray. Add the pasta mixture to the pan and sprinkle with an additional 1½ cups of cheese.
Sprinkle with pepper and bake for 30 minutes or until bubbly and golden brown. Garnish the dish with chopped parsley, if desired.

This was OK BUT THERE WAS NO “ALFREDO” TASTE TO IT. I LOVE YOUR WEBSITE AND USE A LOT OF YOUR RECIPES BUT THIS I PROBABLY WOULDN’T MAKE AGAIN…SORRY
No worries..thank you for trying it 🙂
Can you use heavy whipping cream instead of the half and half? If so how mUch should i use?
I personally have not tried that, so I would need to experiment on the right amount of half & half. I wouldn’t want to tell you the wrong amount.
In stead of making the sauce can i use jared Alfredo sauce???
Yes, of course 🙂 Enjoy!!
I know, it probably doesn’t taste as good, but could you use a jar of alfredo sauce & wood you recommend adding anything to it if I did that to doctor it up some??
You sure could. I would just continue to add the spices on the recipe 🙂 Hope you like it!
