Chicken Alfredo Baked Ziti - a creamy, cheesy pasta bake made with a lighter homemade Alfredo-style sauce (no heavy cream needed)! Tender grilled chicken and ziti are tossed in a rich garlic Parmesan béchamel, layered with plenty of mozzarella, and baked until bubbly and golden. Perfect for family dinners, make-ahead meals, or freezing for later. Comfort food at its best!
Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the minced garlic and sauté for 1 minute, stirring occasionally, until fragrant.
Sprinkle in the flour and stir to combine. Cook for 2 minutes, stirring constantly, to cook out the raw flour taste.
Gradually whisk in the chicken broth until the mixture starts to thicken. Add the milk and continue whisking until the sauce is smooth and thickened.
Stir in the grated Parmesan cheese, salt, and black pepper until the cheese is fully melted and the sauce is creamy.
Remove from heat and stir in the cooked, chopped chicken. Set aside.
For the Pasta
While preparing the white sauce, cook the ziti according to package directions.
Drain the pasta well and return it to the stockpot. Cover to keep warm.
To Assemble
Pour the finished white sauce (with chicken) over the drained ziti and gently stir until evenly combined.
Spread half of the pasta mixture into a greased 9×13-inch baking dish. Sprinkle evenly with half of the shredded mozzarella cheese.
Layer the remaining pasta mixture on top, then sprinkle the rest of the mozzarella evenly over the surface.
Bake uncovered at 375°F for 25 minutes, or until the cheese is fully melted and the top is lightly golden brown.
Remove from the oven, sprinkle with chopped fresh parsley, and serve hot.
