Chicken Alfredo Bake

There's something about a bubbling casserole that makes a kitchen feel like home. I discovered Chicken Alfredo Bake on a chilly Tuesday when I had a container of leftover rotisserie chicken and wanted to make something that felt both effortless and impressive. The moment that creamy Alfredo sauce mingled with the pasta, I knew this would become one of those dishes I'd return to whenever I needed comfort on a plate. It's the kind of meal that doesn't demand perfection, just good ingredients and a hot oven.

I made this for a small dinner party last fall, and I watched my friend Sarah's face the moment she took that first bite, the way the fork lifted a tangle of pasta draped in sauce with melted cheese clinging to it. She closed her eyes, and I realized this wasn't just food; it was the kind of dish that makes people feel cared for. That's when I understood why Alfredo bakes show up at potlucks and family tables again and again.

Ingredients

• Penne pasta, 400g: The tube shape catches and holds onto the creamy sauce, so every bite is coated and satisfying.
• Boneless, skinless chicken breast, 500g diced: Cut yours into roughly half-inch cubes so they cook through quickly and stay tender when baked.
• Olive oil, 1 tbsp: This gets the chicken golden and flavored before everything comes together.
• Salt and black pepper: Season the chicken generously; this is your base layer of flavor.
• Unsalted butter, 2 tbsp: The foundation of your sauce, so don't skip it or use margarine.
• Garlic, 3 cloves minced: Mince it finely so it distributes evenly through the sauce and doesn't leave harsh chunks.
• All-purpose flour, 2 tbsp: This thickens the sauce without lumping if you whisk constantly.
• Whole milk, 480ml: Use full-fat milk; it creates a silkier sauce than lower-fat versions.
• Heavy cream, 120ml: This is what makes the sauce luxurious, so don't substitute with milk alone.
• Grated Parmesan cheese, 80g for sauce plus 30g for topping: Use freshly grated if possible; it melts more smoothly than the pre-shredded kind.
• Ground nutmeg, 1/4 tsp optional: This whisper of warmth is what makes people wonder what the secret ingredient is.
• Shredded mozzarella cheese, 180g: This melts beautifully and creates those golden, bubbly spots.
• Fresh parsley, 2 tbsp chopped: This is your final flourish, bright and herbaceous against the creamy richness.

Instructions

Heat your oven and prepare the stage:

Preheat your oven to 200°C and grease a 23x33cm baking dish with butter or oil so nothing sticks.

Cook the pasta until just shy of soft:

Boil salted water and add the penne, cooking it until it's al dente (still with a slight firmness). It will continue cooking in the oven, so don't make it soft.

Sear the chicken until golden:

Heat olive oil in a large skillet over medium heat and add your diced chicken. Season with salt and pepper, then cook until the pieces are golden outside and opaque inside, about 5 to 7 minutes. Transfer to a plate.

Build your sauce foundation:

In the same skillet, melt butter and add minced garlic, cooking just until fragrant so it doesn't burn. Sprinkle flour over the top and stir constantly for about a minute, which cooks out the raw flour taste.

Create the creamy sauce:

Slowly whisk in the milk and heavy cream, watching the mixture transform from a paste into a silky liquid. Keep whisking as it simmers for 3 to 4 minutes until it thickens just enough to coat the back of a spoon.

Add the soul of the sauce:

Remove from heat and stir in the grated Parmesan, salt, and nutmeg. The cheese will melt into the warm sauce, creating something utterly creamy.

Bring everything together:

In a large bowl, combine the cooked pasta, chicken, and Alfredo sauce, stirring until every piece of pasta is coated and nothing is clumpy.

Transfer to the baking dish:

Pour the mixture into your prepared dish, spreading it evenly with a spatula.

Top with cheese and bake:

Sprinkle the mozzarella and extra Parmesan over the top, covering as much surface as you can. Bake for 20 to 25 minutes until the cheese is melted, bubbling at the edges, and spotted with golden brown.

Rest before serving:

Let it sit for 5 minutes after coming out of the oven; this lets everything set slightly so it holds together when you scoop. Scatter fresh parsley on top just before bringing it to the table.

I'll never forget making this on a Sunday afternoon when my nephew called to say he was bringing his girlfriend over for dinner. The smell of butter and garlic, then the richness of that cream sauce filling the kitchen, gave me this quiet confidence that everything would be fine. Watching them eat together, sharing the same plate like it was nothing, I understood that some dishes do more than nourish; they create moments worth remembering.

The Magic of Creamy Sauces

A proper Alfredo sauce isn't difficult, but it demands your attention and respect. The key is patience: letting the butter melt completely, cooking the garlic just enough to release its aroma without burning it, and whisking the milk in gradually so it incorporates smoothly. Many people rush here, and that's when lumps form or the sauce breaks. I learned to treat those five minutes at the stove like meditation, focusing entirely on the texture changing beneath my whisk, because that's when the magic actually happens.

Making It Your Own

This recipe is forgiving enough to welcome additions without losing its identity. I've folded in steamed broccoli on nights when I wanted green vegetables, stirred in fresh spinach for earthiness, and even added sun-dried tomatoes when I was feeling adventurous. The Alfredo sauce is rich enough to support these variations without being overpowered, and the mozzarella on top will still brown beautifully. Once you master the foundation, you can play.

Shortcuts Worth Taking

Life gets busy, and there's no shame in using a rotisserie chicken from the store instead of cooking your own breasts; you'll save at least fifteen minutes and the results are identical. You could also swap the penne for fettuccine or rigatoni depending on what you have on hand. The only thing I wouldn't compromise on is making the sauce from scratch, because that's where the real flavor lives.

• Use pre-shredded mozzarella if you must, but grate your Parmesan fresh if you can.
• A pinch of lemon zest stirred into the finished sauce brightens everything without adding liquid.
• If you're doubling the recipe, prepare it in two baking dishes rather than stacking everything in one, so the top browns evenly.
