Chicken Alfredo Bake

Featured in: Meals Made At Home

This hearty Italian-American casserole combines al dente penne with seasoned diced chicken in a velvety homemade white sauce. The Alfredo sauce, crafted with butter, garlic, whole milk, and heavy cream, gets its signature depth from grated Parmesan and a hint of nutmeg. After tossing everything together, a generous blanket of shredded mozzarella creates a irresistibly bubbly, golden-brown topping that pairs perfectly with the creamy interior.

The smell of bubbling cheese and cream sauce always pulls everyone into the kitchen before dinner is even ready. I first made this chicken alfredo bake on a rainy Tuesday when I needed something that felt like a hug but didn't require hours of standing at the stove. My roommate actually walked in, took a deep breath, and asked if we were having restaurant food tonight. There's something about that golden brown cheese crust that makes even the most chaotic weeknight feel like a small celebration.

Last winter I made this for my sister's family after her youngest had a rough week at school. She sat at the counter watching me assemble the layers, quietly stealing bits of chicken while I wasn't looking. When it came out of the oven, bubbling and gorgeous, that kid ate three servings and actually smiled for the first time in days. Sometimes pasta is just pasta, and sometimes it's exactly what someone needs.

Ingredients

  • 400 g penne pasta: The ridges catch all that creamy sauce and hold onto it perfectly
  • 500 g boneless chicken breast: Dice it into bite sized pieces so every forkful has both chicken and pasta
  • 1 tbsp olive oil: Just enough to get a nice golden sear on the chicken without drying it out
  • 1/2 tsp salt and 1/4 tsp black pepper: Simple seasoning that layers with the salt in the sauce later
  • 2 tbsp unsalted butter: The foundation of your roux and base for all that velvety goodness
  • 3 cloves garlic: Don't be shy with garlic here, it mellows beautifully in the cream
  • 2 tbsp all-purpose flour: Just enough to thicken the sauce without making it heavy or pasty
  • 480 ml whole milk: Whole milk makes a difference in richness, though I've used 2% in a pinch
  • 120 ml heavy cream: This small amount transforms the texture from good to absolutely luxurious
  • 80 g grated Parmesan: Buy a wedge and grate it yourself, pre-grated has anti-caking agents that make sauce grainy
  • 1/2 tsp salt and 1/4 tsp ground nutmeg: Nutmeg is the secret ingredient that makes white sauces taste professional
  • 180 g shredded mozzarella: Low moisture mozzarella gives you those gorgeous browned cheese bubbles
  • 30 g extra Parmesan: Sprinkled on top for salty, crispy bits everyone fights over
  • 2 tbsp fresh parsley: Adds a bright pop of color and fresh flavor to cut through all that richness

Get your oven ready:
Preheat to 200°C and grease your baking dish with a little butter or oil

Heat olive oil in a large skillet and cook seasoned chicken until golden and cooked through, about 5 to 7 minutes
Start the roux:
Melt butter in the same pan, cook minced garlic for 1 minute, then stir in flour for another minute
Build the sauce:
Gradually whisk in milk and cream, bring to a simmer and let it thicken for 3 to 4 minutes
Add the cheese:
Stir in Parmesan, salt, and nutmeg until melted and smooth, then remove from heat
Combine everything:
Mix cooked pasta, chicken, and that gorgeous sauce in a large bowl until every piece is coated
Assemble the bake:
Transfer to your prepared dish and sprinkle mozzarella and extra Parmesan all over the top
Bake until golden:
20 to 25 minutes until you see bubbly edges and those perfect browned cheese spots
Rest and serve:

This recipe has become my go-to for new neighbors and bad days alike. Something about pulling that bubbling dish out of the oven makes people feel taken care of, like you put extra thought into dinner even when it came together in under an hour.

Making It Ahead

I've assembled this in the morning, kept it covered in the fridge, and just baked it off before dinner guests arrived. Add an extra 5 to 10 minutes to the baking time if it's coming straight from the refrigerator.

Customization Ideas

Sometimes I add steamed broccoli florets or fresh spinach to the pasta mixture for a hit of color and vitamins. Rotisserie chicken works beautifully here if you want to skip the searing step.

Serving Suggestions

A crisp green salad with bright vinaigrette cuts through the richness perfectly. Keep things simple on the side since this dish is the star of the show.

  • Garlic bread is never a bad idea, even with all this pasta
  • Steamed green beans with lemon add welcome freshness
  • A light Chardonnay or Pinot Grigio pairs beautifully

There's something deeply satisfying about a recipe that looks impressive but comes from honest ingredients and straightforward technique. This bake has never failed me.

Recipe Questions & Answers

Can I make this ahead of time?

Yes, assemble the entire dish up to 24 hours in advance, cover tightly, and refrigerate. Bake for an additional 10-15 minutes if going straight from the refrigerator.

What pasta shapes work best?

Penne, rigatoni, and fettuccine all hold the creamy sauce beautifully. Short pasta with ridges or tubes helps capture the Alfredo coating.

How do I store leftovers?

Store in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 180°C (350°F) until warmed through, or microwave individual portions.

Can I freeze this dish?

Freeze before baking for best results. Wrap tightly and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.

What vegetables can I add?

Broccoli florets, spinach, or sautéed mushrooms blend seamlessly into the creamy sauce. Add them during step 7 when combining everything together.

How can I make the sauce thicker?

Simmer the sauce longer to reduce it, or increase the flour to 3 tablespoons. The sauce will also thicken naturally as it bakes.

What You'll Need

Pasta

01 14 oz penne pasta

Chicken

01 1.1 lbs boneless, skinless chicken breast, diced
02 1 tbsp olive oil
03 1/2 tsp salt
04 1/4 tsp black pepper

Alfredo Sauce

01 2 tbsp unsalted butter
02 3 cloves garlic, minced
03 2 tbsp all-purpose flour
04 2 cups whole milk
05 1/2 cup heavy cream
06 3/4 cup grated Parmesan cheese
07 1/2 tsp salt
08 1/4 tsp ground nutmeg

Cheese Topping

01 1 1/2 cups shredded mozzarella cheese
02 1/4 cup grated Parmesan cheese
03 2 tbsp chopped fresh parsley

How to Prepare

Step 01

Preheat Oven and Prepare Dish: Preheat oven to 400°F. Grease a 9x13-inch baking dish with butter or cooking spray.

Step 02

Cook Pasta: Bring a large pot of salted water to a boil. Cook penne pasta according to package directions until al dente, typically 8-10 minutes. Drain thoroughly and set aside.

Step 03

Season and Cook Chicken: Heat olive oil in a large skillet over medium-high heat. Season diced chicken with 1/2 teaspoon salt and 1/4 teaspoon pepper. Add to skillet and cook for 5-7 minutes, stirring occasionally, until golden brown and cooked through. Remove from pan and set aside.

Step 04

Prepare Roux Base: In the same skillet, reduce heat to medium. Melt butter, then add minced garlic and sauté for 1 minute until fragrant. Sprinkle in flour and cook, whisking constantly, for 1 minute to form a roux.

Step 05

Create Creamy Sauce: Slowly whisk in whole milk and heavy cream, ensuring no lumps form. Bring mixture to a gentle simmer over medium heat, whisking frequently for 3-4 minutes until sauce thickens enough to coat the back of a spoon.

Step 06

Add Cheese and Seasoning: Remove skillet from heat. Stir in grated Parmesan cheese, remaining salt, and ground nutmeg until cheese is completely melted and sauce is smooth and velvety.

Step 07

Combine Components: In a large mixing bowl, add cooked pasta, seasoned chicken, and Alfredo sauce. Toss thoroughly until every piece of pasta is evenly coated with sauce.

Step 08

Assemble Casserole: Transfer the pasta mixture to the prepared baking dish, spreading evenly. Sprinkle shredded mozzarella and additional Parmesan cheese across the surface in a uniform layer.

Step 09

Bake Until Golden: Bake for 20-25 minutes until cheese is fully melted, bubbly, and develops golden-brown spots on top. The edges should be slightly crispy.

Step 10

Rest and Serve: Remove from oven and let casserole rest for 5 minutes to set. Garnish with chopped fresh parsley before serving hot.
