Oven-Baked Cheesy Chicken Alfredo Bake – Creamy, Dreamy Comfort Food 🍗🧀✨

Penne gets boiled about a minute short of al dente for this Oven-Baked Cheesy Chicken Alfredo Bake, since it keeps cooking in the oven and would turn mushy if fully cooked on the stovetop first. The chicken is cut into bite-sized pieces and seared in a skillet, and the Alfredo sauce is built right there from scratch — butter, garlic, heavy cream, and cream cheese whisked together with Parmesan — rather than relying on a jar. Everything gets tossed together in one bowl before it goes into the dish, so every bite of pasta and chicken is coated in that homemade sauce.

Why This Bake Works So Well

A creamy casserole that's earned its spot as a family favorite.

• Rich and satisfying — a great mix of cheesy, creamy, and hearty
• Quick to put together — built from simple pantry ingredients
• Great as leftovers — reheats beautifully for lunch the next day
• A hit with everyone — kids, teens, and adults all go back for more

Think classic Alfredo pasta — buttery, garlicky, cheesy — baked until golden and bubbly, filling the kitchen with an amazing smell along the way.

Why You'll Want to Make This

• Packed with protein from the chicken and cheese
• A genuinely simple one-pan dinner for busy weeknights
• Looks fancy, takes barely any time to prep
• Great for assembling ahead and baking later

What You'll Need

• 12 ounces penne pasta (or your favorite shape)
• 1½ pounds boneless, skinless chicken breast, cut into bite-sized pieces
• 2 tablespoons butter
• 3 cloves garlic, minced
• 2 cups heavy cream
• 4 ounces cream cheese, softened
• 1 cup grated Parmesan cheese, divided
• 1 cup shredded mozzarella cheese
• 1 teaspoon garlic powder
• ½ teaspoon Italian seasoning
• Salt and black pepper to taste
• 2 tablespoons chopped parsley (for garnish)

Equipment You'll Need

• Large pot for boiling pasta
• Mixing bowl
• 9×13-inch baking dish
• Wooden spoon or spatula
• Foil (for covering while baking)

Ways to Customize It

This recipe takes well to all kinds of tweaks:

• Veggies: add spinach, broccoli, or roasted mushrooms
• Protein: swap the chicken for shrimp, turkey, or Italian sausage
• Cheese: try provolone or fontina in place of the mozzarella
• Lighter version: use whole wheat pasta and half-and-half in place of heavy cream
• Gluten-free: swap in gluten-free pasta
• Short on time: the shortcut version with store-bought Alfredo sauce starts from already-cooked chicken, so there is no sauce step at all

How to Make Oven-Baked Cheesy Chicken Alfredo Bake

Step 1: Cook the Pasta

Preheat your oven to 375°F (190°C).

Bring a large pot of salted water to a boil. Cook the penne until just al dente, about a minute short of the package instructions. Drain and set aside.

Step 2: Sear the Chicken

Season the chicken with the garlic powder, salt, and pepper.

Sear in a large skillet over medium-high heat until golden and cooked through, about 6–8 minutes, then remove and set aside.

Step 3: Make the Sauce

In the same skillet, melt the butter over medium heat and sauté the garlic until fragrant, about 30 seconds.

Whisk in the heavy cream and cream cheese until smooth, then stir in half the Parmesan and the Italian seasoning until melted into a sauce.

Step 4: Combine and Assemble

Add the cooked pasta and seared chicken to the sauce, stirring until everything is evenly coated.

Transfer the mixture to a greased 9×13-inch baking dish and top with the mozzarella and remaining Parmesan.

Step 5: Bake

Cover with foil and bake for 15 minutes. Remove the foil and bake another 10–15 minutes, until the top turns golden and bubbly.

Step 6: Garnish and Serve

Let it rest for 5 minutes before serving. Sprinkle with fresh parsley and dig into that cheesy, creamy dinner.

What to Serve With It

Rich and filling, so pair it with something fresh and light:

• Garlic bread or buttery rolls
• A crisp green salad with lemon vinaigrette
• Roasted asparagus or steamed broccoli
• A glass of white wine (Pinot Grigio or Chardonnay pairs beautifully)

Storing and Reheating

• Fridge: Store leftovers in an airtight container for up to 4 days
• Freezer: Freeze the baked casserole for up to 2 months. Thaw overnight in the fridge before reheating
• Reheat: Warm individual portions in the microwave, or cover the whole dish with foil and bake at 350°F (175°C) until heated through
