When you crave cozy comfort with almost no effort, this dump-and-bake chicken Alfredo delivers. Everything cooks together in one pan—dry pasta, raw chicken, creamy sauce—so you get a silky, garlicky Alfredo with juicy bites of chicken and perfectly tender noodles. No boiling, no stirring at the stove, and no sink full of pots.

I make this on weeknights when I need dinner to take care of itself. You’ll toss everything into a casserole dish, cover it, and let the oven do the heavy lifting. In under an hour, you’ll have a bubbling, golden, creamy chicken Alfredo that tastes like you fussed.

Why This Easy Dump-and-Bake Chicken Alfredo Works

Hands-off cooking: The oven simmers the pasta right in the sauce, so you skip boiling water and draining noodles.
Perfectly tender pasta: The pasta absorbs seasoned liquid and cream, which means every bite tastes rich and well-salted.
Creamy, not gloopy: A simple combo of broth, cream, and Parmesan creates a silky sauce that clings instead of clumping.
Family-friendly flavor: Garlic, Parmesan, and a touch of Italian seasoning keep it classic and crowd-pleasing.
Scales up easily: Double the recipe in a large 9×13 pan for a crowd, or halve it in an 8×8 for a cozy dinner.

Ingredients

Uncooked pasta: 12 ounces of short pasta like penne, rotini, or ziti
Chicken: 1.25–1.5 pounds boneless, skinless chicken breasts or thighs, cut into 1-inch pieces
Chicken broth: 3 cups, low-sodium
Heavy cream: 1 cup (or half-and-half for lighter)
Parmesan: 1 cup freshly grated, plus more for serving
Cream cheese: 3 ounces, softened, for extra silkiness
Garlic: 3–4 cloves, minced (or 1 teaspoon garlic powder)
Italian seasoning: 1 teaspoon
Salt and pepper: to taste (start with 1 teaspoon kosher salt, 1/2 teaspoon black pepper)
Olive oil or butter: 1 tablespoon, for richness
Mozzarella: 1 cup shredded, optional for a melty top
Fresh parsley: chopped, for finishing

How to Make This Creamy Oven Chicken Alfredo

Prep the pan

Heat oven to 400°F (200°C). Grease a 9×13 baking dish with olive oil or butter.

Layer the base

Scatter the uncooked pasta evenly in the dish.
Top with the raw chicken pieces. Season with salt, pepper, and Italian seasoning.

Blend the sauce

In a bowl, whisk together chicken broth, heavy cream, minced garlic, and cream cheese until mostly smooth. Some little bits of cream cheese are fine; they melt in the oven.
Stir in 1 cup Parmesan.

Assemble and bake

Pour the sauce over the pasta and chicken. Press down to ensure the pasta sits in liquid. Cover the dish tightly with foil.
Bake for 30 minutes covered. This steams the pasta and gently cooks the chicken.
Remove foil, stir well, and check liquid. If pasta looks dry, add 1/4 to 1/2 cup hot water or broth.
Top with mozzarella if using. Bake 10–15 minutes uncovered until the pasta is al dente, sauce is creamy, and the top is lightly golden.

Finish and serve

Let it rest 5 minutes. The sauce thickens as it stands.
Sprinkle with fresh parsley and extra Parmesan. Taste and adjust salt and pepper.

Pro tips for best texture

Use short, tubular pasta. It cooks evenly and holds creamy sauce well.
Grate your own Parmesan. Pre-grated can clump. Freshly grated melts smoothly.
Check at the 30-minute mark. Every oven runs different. Add a splash of hot liquid if needed.
Cut chicken evenly. Uniform 1-inch pieces cook through right as pasta finishes.

How to Store Leftover Chicken Alfredo

Cool quickly: Spread leftovers in a shallow container and refrigerate within 2 hours.
Refrigerate: Store in an airtight container for up to 4 days.
Freeze: Freeze in portions for up to 2 months. Thaw overnight in the fridge.
Reheat gently: Add a splash of milk or broth, cover, and warm in the microwave at 50–70% power, stirring every minute, until creamy.

Benefits of Making Chicken Alfredo in the Oven

One pan, one bake: Minimal prep and minimal dishes.
Set it and forget it: You can handle sides or clean-up while dinner bakes.
Consistent results: The covered bake steams pasta evenly in flavorful liquid.
Customizable: You can tweak creaminess, cheese blend, or add-ins without changing the method.
Weeknight-friendly: From pantry to table in under an hour with simple ingredients.

What to Avoid for Best Results

Don’t skimp on liquid. Dry spots mean crunchy pasta. Ensure noodles sit in sauce.
Don’t overbake uncovered. The sauce can reduce too much. Check at 10 minutes.
Don’t use pre-cooked pasta. It turns mushy in the oven. Start with dry pasta.
Don’t skip the foil phase. Covered time is crucial for tender pasta and juicy chicken.
Don’t rely on pre-shredded cheese only. Anti-caking agents can hinder melting.

Easy Variations to Try

Broccoli Chicken Alfredo: Add 2 cups small broccoli florets during the last 10–15 minutes of baking.
Spinach Alfredo: Stir in 3–4 cups baby spinach after baking; the heat wilts it perfectly.
Mushroom and Chicken: Add 8 ounces sliced mushrooms at the start for earthy flavor.
Bacon Ranch Alfredo: Sprinkle 1/2 teaspoon ranch seasoning into the sauce and top with crisp bacon.
Lemon Herb: Finish with zest of 1 lemon and extra parsley for brightness.
Three-Cheese: Use a blend of Parmesan, Romano, and mozzarella for extra depth.
Gluten-Free: Swap in a sturdy gluten-free pasta and check early; add liquid as needed.
Lighter Option: Use half-and-half and reduce cream cheese to 2 ounces; sauce will be slightly thinner but still creamy.

FAQ

Can I use rotisserie chicken?

Yes. Stir in 2–3 cups shredded cooked chicken after the initial 30 minutes when you remove the foil. Bake uncovered 10–12 minutes to heat through.

Will the chicken cook through with the pasta?

Yes. Cut pieces to 1 inch. After about 40–45 minutes total, the chicken reaches 165°F and stays tender in the creamy sauce.

Can I substitute milk for cream?

You can use whole milk, but add 1 extra ounce of cream cheese and 2 tablespoons butter to keep the sauce silky.

What pasta shape works best?

Penne, rotini, ziti, or rigatoni. Avoid very small shapes like elbows or pastina; they can overcook quickly.

How do I prevent a greasy sauce?

Use freshly grated Parmesan, measure cream accurately, and avoid over-reducing during the uncovered bake. Add a splash of hot broth if it tightens too much.

Can I make it ahead?

Yes, assemble up to 6 hours ahead, cover, and refrigerate. Add 5–10 minutes to the covered bake time since it starts cold.
