Easy Chicken Alfredo Bake with Store-Bought Sauce

Before I say anything else — thank you for being here! Recipes like this one remind me why I love sharing food that feels like a hug in casserole form. This Oven-Baked Cheesy Chicken Alfredo Bake is cozy, creamy, and loaded with gooey cheese — the kind of dinner that makes everyone go quiet after the first bite (because they’re too busy savoring it!).

This is the shortcut version. It starts from chicken that is already cooked and a jar of Alfredo sauce, so there is no sauce to make and no raw chicken to cook through — you mix, layer and bake. If you would rather build the sauce yourself from butter, cream and Parmesan with raw chicken breast, use our from-scratch chicken Alfredo bake instead.

How to Make This Easy 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 penne pasta until just al dente (about 1 minute less than package instructions). Drain and set aside.

Step 2: Mix the Filling

In a large mixing bowl, combine shredded chicken, Alfredo sauce, garlic powder, Italian seasoning, half of the mozzarella, and half of the Parmesan cheese. Add cooked pasta and stir until everything is evenly coated.

Step 3: Assemble the Casserole

Spread half the pasta mixture into a 9×13-inch baking dish. If using, dollop ricotta or cottage cheese evenly over the first layer. Add the remaining pasta mixture on top. Sprinkle with the remaining mozzarella and Parmesan.

Step 4: Bake

Cover the dish with foil and bake for 20 minutes. Remove foil and bake for another 10–15 minutes, or until the top is golden and bubbly.

Step 5: Garnish and Serve

Let the casserole rest for 5 minutes before serving. Sprinkle with fresh parsley and enjoy that cheesy, creamy deliciousness!

What to Serve with Chicken Alfredo Bake

This dish is rich and satisfying, so pair it with something fresh and light:

• Garlic bread or buttery rolls

• Glass of white wine (Pinot Grigio or Chardonnay pairs beautifully!)

Storage and Reheating

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze baked casserole for up to 2 months. Thaw overnight in the fridge before reheating.
