I first tried this when my youngest asked for something cheesy like restaurant Alfredo but heartier After the first bite no one could resist going back for seconds
Ingredients
- Penne or rigatoni pasta: ensures every bite gets coated with sauce look for brands labeled bronze cut for a better texture
- Boneless skinless chicken breasts: stay juicy and tender when diced fresh ask the butcher for the plumpest pieces
- Olive oil: helps brown the chicken and keeps it moist choose a fruity extra virgin if you can
- Salt and black pepper: highlight all the other flavors opt for fresh cracked black pepper for extra aroma
- Unsalted butter: builds a rich base for the Alfredo sauce European style has a deeper flavor
- Fresh garlic: brings an irresistible aroma and depth use firm unblemished cloves
- All purpose flour: thickens the sauce smoothly sift to avoid lumps
- Whole milk and heavy cream: combine for a perfectly creamy texture use the freshest available for best results
- Parmesan cheese: gives sharp salty flavor freshly grated melts best and has more flavor than pre shredded
- Nutmeg: adds warmth and nuance optional but classic in Alfredo a pinch goes a long way
- Shredded mozzarella: melts into a gooey topping buy a block and shred for best melt
- Fresh parsley: gives color and a burst of freshness only add just before serving for vivid color
Instructions
- Preheat the Oven:
- Set your oven rack to the middle position and preheat to 200 degrees Celsius or 400 degrees Fahrenheit Lightly grease your baking dish with butter or a bit of olive oil to prevent sticking
- Cook the Pasta:
- Bring a large pot of salted water to a lively boil Add the pasta and stir cook until just al dente not all the way soft as it will continue cooking in the oven Drain and set aside in a colander
- Sauté the Chicken:
- While the pasta cooks heat olive oil in a large skillet over medium high heat Add the diced chicken spreading it out to cook evenly Sprinkle with salt and black pepper Cook for five to seven minutes stirring only as needed to get golden spots on the surface The chicken should be cooked through but not dry Remove and set aside
- Make the Garlic Roux:
- Return the skillet to medium heat and melt the butter Once the butter foams add minced garlic Stir constantly for about a minute until it softens and becomes very fragrant but do not let it brown
- Build the Alfredo Sauce:
- Sprinkle in the flour while whisking continuously to coat the garlic and make a smooth paste Keep whisking for a full minute to cook off the raw flour taste
- Thicken the Cream Base:
- Slowly drizzle in the whole milk and heavy cream whisking vigorously to keep the sauce smooth and lump free Allow the mixture to simmer for several minutes until it begins to thicken slightly keep stirring the whole time to prevent scorching
- Melt in the Cheese:
- Add freshly grated Parmesan salt nutmeg if using and more black pepper Stir constantly until the cheese disappears and the sauce is glossy and creamy Give it another two minutes to fully thicken
- Combine Pasta Chicken and Sauce:
- Tip the cooked chicken and drained pasta back into the skillet with the Alfredo sauce Toss gently with a wooden spoon or silicone spatula until every piece is coated in the sauce
- Assemble the Bake:
- Scoop or pour the creamy pasta mixture into your prepared baking dish Spread evenly Sprinkle a generous layer of shredded mozzarella then finish with extra Parmesan for that golden crust
- Bake to Perfection:
- Slide the dish onto the oven middle rack Bake uncovered for about twenty minutes Keep an eye out the cheese should melt fully and take on a pale golden color along the edges
- Rest and Garnish:
- Remove the bake and let it rest for five minutes before serving Scatter chopped fresh parsley over the top for color and freshness Serve piping hot for best flavor and texture

Storage Tips
Let leftovers cool to room temperature before covering tightly and refrigerating You can keep leftovers for up to four days in the fridge Reheat covered in the oven at 175 degrees Celsius or 350 degrees Fahrenheit until piping hot Add a splash of milk or cream before reheating to loosen up the sauce
Ingredient Substitutions
Use rotisserie chicken for an even quicker assembly If you are out of heavy cream try using all whole milk just expect a slightly lighter sauce Gluten free pasta works well here but be sure to cook it al dente to prevent mushiness Monterey Jack or fontina can stand in for some of the mozzarella for a different cheese pull
