Ingredients

For the Pasta Bake:

• 1 lb. (454g) penne pasta or rigatoni
• 2 lbs. (907g) boneless, skinless chicken breasts, cut into bite-sized pieces
• 4 tablespoons unsalted butter
• 6 cloves garlic, minced (about 2 tablespoons)
• 3 tablespoons all-purpose flour
• 2 cups (480ml) whole milk
• 1 cup (240ml) heavy cream
• 2 cups (200g) mozzarella cheese, shredded
• 1 cup (100g) Parmesan cheese, freshly grated
• 1 teaspoon Italian seasoning
• 1 teaspoon garlic powder
• ½ teaspoon onion powder
• Salt and black pepper to taste
• 2 tablespoons olive oil
• ½ cup (50g) Panko breadcrumbs (optional for extra crunch)
• Fresh parsley, chopped for garnish

The combination of whole milk and heavy cream creates the perfect consistency for the sauce, neither too thin nor overly thick. Freshly grated Parmesan melts far better than pre-shredded varieties and adds a depth of flavor that elevates this garlic chicken pasta casserole to restaurant quality.

Pro Tips

Master the Garlic Sauce: The foundation of this Cheesy Garlic Chicken Pasta Bake lies in creating a perfectly smooth, lump-free sauce. After adding your flour to the melted butter and garlic, cook it for at least two minutes to eliminate any raw flour taste. When adding your liquids, pour slowly while whisking constantly to prevent clumping. If your sauce seems too thick, add milk a tablespoon at a time until you reach a consistency that coats the back of a spoon but still flows easily.

Don’t Overcook Your Pasta: Since the pasta will continue cooking in the oven, undercook it by about two minutes less than the package directions suggest. This prevents mushy noodles and ensures your final dish has that perfect al dente texture everyone craves. Reserve at least one cup of pasta water before draining, as this starchy liquid can help adjust your sauce consistency if needed.

Layer for Maximum Flavor: Season your chicken generously before cooking, and don’t skip browning it properly. That golden caramelization adds incredible depth to your cheesy garlic pasta bake. When assembling, make sure every piece of pasta gets coated with sauce, and distribute the chicken evenly throughout for consistent flavor in every serving.

Instructions

Step 1: Prepare Your Ingredients

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with butter or cooking spray. Bring a large pot of salted water to a rolling boil for your pasta. While the water heats, cut your chicken breasts into uniform bite-sized pieces, about 1-inch cubes, which ensures even cooking. Pat the chicken dry with paper towels and season generously with salt, pepper, half the Italian seasoning, and garlic powder. Mince your garlic cloves finely, as larger pieces won’t distribute evenly throughout the sauce.

Step 2: Cook the Pasta

Add your pasta to the boiling water and cook for 2 minutes less than the package directions recommend. For most penne or rigatoni, this means about 8-9 minutes. Stir occasionally to prevent sticking. Before draining, scoop out and reserve one cup of the starchy pasta water, which you can use later to adjust sauce consistency. Drain the pasta thoroughly and set aside, but don’t rinse it, as the surface starch helps the sauce cling better.

Step 3: Brown the Chicken

Heat olive oil in a large skillet over medium-high heat until it shimmers. Add your seasoned chicken pieces in a single layer, working in batches if necessary to avoid overcrowding. Cook without moving for 3-4 minutes until golden brown on one side, then flip and cook another 3-4 minutes until cooked through and the internal temperature reaches 165°F (74°C). The chicken doesn’t need to be completely done at this stage since it will finish cooking in the oven. Transfer the cooked chicken to a plate and set aside.

Step 4: Create the Garlic Cream Sauce

In the same skillet, reduce heat to medium and add butter. Once melted and foaming, add your minced garlic and sauté for about 1 minute until fragrant but not browned, as burnt garlic tastes bitter. Sprinkle the flour over the butter and garlic, whisking constantly to create a smooth roux. Cook this mixture for 2 minutes, stirring continuously. Gradually pour in the milk and heavy cream while whisking vigorously to prevent lumps from forming. Continue cooking, stirring frequently, until the sauce thickens enough to coat the back of a spoon, about 5-6 minutes.

Step 5: Add Cheese and Seasonings

Remove the skillet from heat and stir in 1½ cups of mozzarella and ¾ cup of Parmesan cheese, reserving the rest for topping. Add the remaining Italian seasoning, onion powder, and season with salt and pepper to taste. The residual heat will melt the cheese into a smooth, creamy sauce. If your sauce seems too thick, add some reserved pasta water a tablespoon at a time until you achieve a consistency similar to heavy cream.

Step 6: Combine and Assemble

In a large mixing bowl, combine your cooked pasta, browned chicken, and the entire batch of garlic cream sauce. Toss everything together until every piece of pasta and chicken is thoroughly coated. Transfer this mixture to your prepared baking dish, spreading it evenly. Sprinkle the remaining mozzarella and Parmesan cheese over the top, creating a generous layer. For extra texture, mix the Panko breadcrumbs with a tablespoon of melted butter and scatter over the cheese layer.

Step 7: Bake to Golden Perfection

Place the baking dish in your preheated oven and bake for 20-25 minutes until the cheese is melted, bubbly, and golden brown around the edges. If you want an extra-crispy top, turn on your broiler for the last 2-3 minutes, watching carefully to prevent burning. The Cheesy Garlic Chicken Pasta Bake is ready when you see bubbling sauce around the edges and the cheese has developed those irresistible golden-brown spots. Remove from the oven and let it rest for 5 minutes before serving, allowing the sauce to thicken slightly and making it easier to serve clean portions.

Variations

Vegetable-Loaded Version: Transform this into a complete one-pan meal by adding 2 cups of vegetables. Sauté chopped broccoli florets, bell peppers, or spinach along with the garlic before making the sauce. Mushrooms work beautifully in this creamy garlic chicken bake, adding an earthy flavor that complements the cheese perfectly.

Spicy Kick: For those who love heat, add ½ teaspoon of red pepper flakes to the garlic sauce or mix in a few tablespoons of diced jalapeños. You can also use pepper jack cheese instead of mozzarella for a southwestern twist on this classic comfort dish.

Bacon Lovers’ Dream: Create a garlic pasta with bacon by cooking 6-8 strips of bacon until crispy, then crumbling it into the pasta mixture before baking. The smoky, salty bacon adds another layer of flavor that pairs exceptionally well with the creamy garlic sauce and chicken. Reserve some bacon for sprinkling on top before serving for extra visual appeal and crunch.

Storage and Serving

Store leftover Cheesy Garlic Chicken Pasta Bake in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes, or warm the entire dish covered with foil in a 350°F (175°C) oven for 20 minutes until heated through. This casserole freezes beautifully for up to 3 months. Assemble the dish completely but don’t bake it, then wrap tightly with plastic wrap and aluminum foil. Thaw overnight in the refrigerator before baking as directed, adding an extra 10 minutes to the cooking time.

For serving, this pasta bake shines as a complete meal, but pairing it with a crisp Caesar salad or simple green salad dressed with lemon vinaigrette cuts through the richness perfectly. Garlic bread might seem redundant given the garlic in the dish, but honestly, it’s never a bad idea for soaking up any extra sauce. A light, sparkling beverage or crisp white wine complements the creamy, cheesy flavors wonderfully. Garnish each serving with fresh chopped parsley and an extra sprinkle of Parmesan for that restaurant-quality presentation.
