Why This Recipe Works

Comfort food at its finest: Warm, filling, and creamy — this bake delivers restaurant-style flavor in a home-cooked meal.
An irresistible sauce: The homemade Alfredo is silky and rich, the highlight of the bake.
Great for leftovers: Use cooked chicken and pasta you already have — make the sauce and assemble for a quick casserole.
Ingredients
The list may look long, but most items are pantry staples. These ingredients combine for a balanced, flavorful casserole.
You will need:
- 12 oz penne pasta, cooked
- 3 cups rotisserie chicken, diced
- 3 tbsp butter
- 2 tbsp flour
- 1 clove garlic, minced
- 2 cups milk
- 1 cup heavy cream
- 3/4 cup Parmesan cheese, shredded
- 2 cups shredded Italian cheese blend
- Salt and pepper, to taste
- 1 tsp oregano
- 1 tsp thyme
- 1/2 tsp cumin
- Fresh parsley for garnish
How To Make Chicken Alfredo Bake
- Prepare: Preheat oven to 350°F (180°C). Coat a 3-quart (9×13-inch) casserole dish with cooking spray.
- Make the Alfredo sauce: In a large skillet over medium heat, melt butter. Add minced garlic and flour, whisking and cooking for about 1 minute to remove the raw flour taste.
- Finish the sauce: Gradually whisk in the milk and heavy cream. Simmer, whisking constantly, until the sauce thickens. Stir in the Parmesan until melted and smooth. Season with cumin, oregano, thyme, salt, and pepper.
- Assemble: In a large bowl combine cooked pasta and diced chicken. Pour the Alfredo sauce over the top and toss to coat evenly. Transfer the mixture to the prepared baking dish and sprinkle the shredded Italian cheese blend across the top.
- Bake and serve: Bake uncovered for about 20 minutes, until the casserole is bubbly and the cheese just begins to brown. Remove, sprinkle with fresh parsley, and serve warm.
Tips To Make The Best Recipe
- Short pasta works best: Use penne, rotini, or elbow macaroni for easy scooping and even sauce coverage.
- Make classic Alfredo: For a traditional pasta plate, toss this sauce with cooked fettuccine instead of baking.
- Shortcut with rotisserie: Pre-cooked or store-bought rotisserie chicken saves time and adds flavor.
- Cook pasta al dente: It will finish cooking in the oven and won’t become mushy.
- Cheese choices: Use mozzarella alone for a milder melt, or an Italian blend for more flavor.
How To Store Chicken Alfredo Bake
In the fridge: Store leftovers in an airtight container or cover the baking dish and refrigerate for 3–4 days.
In the freezer: Portion into freezer-safe containers or bags and freeze up to 3 months.
Reheating: Reheat in an oven-safe dish at 350°F (175°C) for 10–15 minutes covered, then 5 minutes uncovered. If frozen, thaw overnight in the refrigerator before reheating for best results.
FAQs About Chicken Alfredo Bake
What can I add to chicken Alfredo to make it taste better?
This sauce is excellent on its own, but additions like cooked bacon, steamed broccoli, sautéed spinach, or a sprinkle of Romano cheese can elevate the flavor and texture.
What is the secret to thick Alfredo sauce?
A balance of butter, heavy cream, a touch of flour, and plenty of cheese creates a thick, velvety sauce. A small amount of cream cheese can also help thicken it if desired.

Yes. Assemble the casserole, cover tightly, and refrigerate overnight. Bake when you’re ready to serve.
What to serve with chicken Alfredo pasta?
This rich bake pairs well with a light salad or crusty bread for dipping. Simple green salads or garlic bread balance the creaminess.
