Chicken Alfredo Bake Recipe
Chicken alfredo bake is fettuccine alfredo dressed for a potluck: penne and chicken folded through a from-scratch garlic-parmesan cream sauce, capped with mozzarella, and baked until the corners bubble and brown. The casserole format solves alfredo's great weakness — sauce that tightens as it cools — by design: the pasta drinks it in the oven and comes out lush all the way through. Feeds eight, assembles a day ahead, and disappears at a rate that should be studied.

- 1 lb penne
- 3 cups cooked chicken, chopped (rotisserie or leftover baked breasts)
- 4 tbsp butter
- 4 cloves garlic, minced
- 3 tbsp flour
- 2 cups whole milk
- 1 1/2 cups heavy cream
- 1 1/2 cups grated parmesan
- 1 tsp Italian seasoning, 3/4 tsp salt, 1/2 tsp pepper, pinch of nutmeg
- 2 cups shredded mozzarella
- Chopped parsley, to serve
Instructions
- Heat the oven to 375°F. Boil the penne 2 minutes shy of al dente; drain.
- Melt the butter; cook the garlic 30 seconds, then the flour for 1 minute.
- Whisk in the milk and cream gradually; simmer 3–4 minutes until it coats a spoon.
- Off the heat, whisk in the parmesan, Italian seasoning, salt, pepper, and nutmeg.
- Fold the pasta and chicken through the sauce; spread in a greased 9x13 and top with mozzarella.
- Bake 20–25 minutes until bubbling and golden at the edges. Rest 5 minutes; parsley; serve.
Ingredient Substitutions
| Ingredient | Substitute | Notes |
|---|---|---|
| Penne | Rotini, ziti, or broken fettuccine | Sauce-holding shapes preferred |
| Heavy cream | All whole milk + 1 extra tbsp flour | Lighter but still silky |
| Chicken | Add 2 cups steamed broccoli | The chicken-broccoli-alfredo triad |
| Mozzarella top | Provolone + buttered panko | Crunchy-top faction |
Storage & Reheating
Refrigerate up to 4 days; reheat portions with a splash of milk to re-silk the sauce.
Freezes well baked or unbaked up to 3 months — the casserole format protects the alfredo. Bake from thawed, covered, plus 15 minutes.
Frequently Asked Questions
Why does restaurant alfredo separate when I make it at home?
True alfredo (butter + parm alone) is fragile. This bake uses a light roux-stabilized sauce — the flour keeps it emulsified through baking, storage, and reheating. It's the casserole-proof alfredo.
What does the nutmeg do?
A pinch is the classic cream-sauce secret — you don't taste “nutmeg,” you taste a warmer, rounder sauce. Every French white sauce does this; grandmothers approved it long ago.
Can I assemble it ahead?
Fully, a day in advance, refrigerated with the cheese on. Bake straight from the fridge plus 10 minutes. This is why it staffs so many potlucks.
How do I keep the pasta from overcooking?
The 2-minutes-shy boil is load-bearing — the penne finishes in the oven. Fully cooked pasta going in means soft pasta coming out.
