Essential Ingredients for Chicken Alfredo Bake

This rich and creamy comfort food casserole comes together with a handful of simple ingredients.

• Pasta: 1 lb (450g) of a short pasta shape, like penne or ziti
• Chicken: 2 large boneless, skinless chicken breasts, cut into bite-sized pieces
• For the Alfredo Sauce:
  • 4 tablespoons butter
  • 3 cloves of garlic, minced
  • 2 cups heavy cream
  • 1 cup whole milk
  • 1 ½ cups freshly grated Parmesan cheese, divided
• Seasoning: 1 teaspoon salt & ½ teaspoon black pepper

Ingredients Notes

A little more detail on our key ingredients will ensure your Alfredo bake is perfectly creamy and delicious.

• The Pasta: For a baked casserole like this, it is best to use a sturdy, short pasta shape that can hold onto the creamy sauce well. Penne, ziti, or rigatoni are all fantastic choices. It is very important to only cook the pasta until it is very al dente, a minute or two less than the package directions, as it will continue to cook in the sauce as it bakes.
• The Chicken: We use boneless, skinless chicken breasts cut into uniform, bite-sized cubes. This ensures that the chicken cooks quickly and evenly in the skillet before being added to the casserole. You can also use a rotisserie chicken shortcut by stirring in about 3 cups of shredded, pre-cooked chicken at the end.
• The Alfredo Sauce: Our simple, from-scratch Alfredo sauce is what makes this dish so spectacular. For the richest and most stable sauce, it is essential to use full-fat heavy cream. Using freshly grated Parmesan cheese from a block, not the pre-shredded kind, is the other non-negotiable secret to a smooth, velvety sauce that won’t become grainy.
• The Cheese Topping: While most of the Parmesan cheese goes into the sauce itself, we save a little bit to sprinkle on top of the casserole before it bakes. As it bakes, this cheese will melt into a beautiful, golden-brown, and slightly crispy crust. You could also use shredded mozzarella on top for an even gooier, more “cheese-pull” worthy result.

How to Make The Ultimate Creamy Chicken Alfredo Bake

Let’s walk through the simple steps to create this decadent and comforting one-pan dinner.

• Step 1: Prepare the Oven and Cook the Pasta. First, preheat your oven to 190°C (375°F) and grease a 9×13 inch baking dish. Cook your pasta in a large pot of salted water according to the package directions, but be sure to undercook it by about 2 minutes so it is very al dente. Drain the pasta and set it aside.
• Step 2: Cook the Chicken. While the pasta is cooking, season your bite-sized chicken pieces with salt and pepper. In a large skillet or Dutch oven, cook the chicken over medium-high heat until it is golden brown and cooked through. Remove the chicken from the skillet and set it aside.
• Step 3: Create the Alfredo Sauce. In the same skillet over medium heat, melt the butter. Add the minced garlic and cook for one minute until fragrant. Slowly whisk in the heavy cream and the milk, and bring the mixture to a gentle simmer, letting it cook for 3-5 minutes until it has thickened slightly.
• Step 4: Add the Cheese. Reduce the heat to low. Gradually stir in 1 cup of the freshly grated Parmesan cheese. Continue to stir until the cheese has completely melted and the sauce is smooth and velvety.
• Step 5: Assemble the Casserole. Add the cooked pasta and the cooked chicken to the skillet with the Alfredo sauce. Gently stir everything together until the pasta and chicken are completely and beautifully coated in the sauce.
• Step 6: Bake to Bubbly Perfection. Pour the pasta mixture into your prepared baking dish and spread it into an even layer. Sprinkle the remaining ½ cup of Parmesan cheese over the top. Bake for 15-20 minutes, until the casserole is hot and the sauce is bubbly around the edges.
• Step 7: Broil and Rest. For a beautiful golden-brown top, you can place the casserole under the broiler for the last 1-2 minutes of cooking. Let the casserole rest for at least 5 minutes before serving.

Storage Options

This creamy chicken Alfredo bake makes for fantastic leftovers. Once the casserole has cooled completely, you can either cover the baking dish tightly with foil or transfer individual portions to an airtight container. It will stay fresh in the refrigerator for up to 4 days.

To reheat, it’s best to warm the casserole in the microwave or in the oven. The sauce will thicken considerably in the refrigerator, so you may want to add a splash of milk when you are reheating it to help restore its creamy consistency.

Variations and Substitutions

This classic Alfredo casserole is a wonderful template that you can easily adapt to your family’s tastes. To add some extra nutrients and colour, you can stir in about a cup of steamed broccoli florets or a few handfuls of fresh baby spinach to the pasta before you bake it. For a different flavour, feel free to add some cooked and crumbled bacon or some sautéed mushrooms to the dish. If you don’t have chicken, this creamy sauce is also absolutely fantastic with sautéed shrimp.

Practical & Valuable Tips

The most important tip for a perfect pasta bake is to slightly undercook your pasta initially, as it will continue to cook and absorb the sauce in the oven. For the absolute creamiest and smoothest Alfredo sauce, always use freshly grated Parmesan cheese from a block and stir it into the sauce over a very low heat. Finally, letting the finished casserole rest for at least 5 minutes before you serve it is a crucial step that allows the sauce to set up and thicken, making it much easier to serve.

Frequently Asked Questions

1. Can I just use a jar of Alfredo sauce to make this recipe even faster? Yes, you can absolutely use a 15-ounce jar of your favorite store-bought Alfredo sauce as a shortcut. You would simply cook your chicken and pasta, and then toss them together with the jarred sauce before baking it with the cheese on top.
2. My Alfredo sauce seems too thin. What should I do? If your sauce seems thin before you add the pasta, you can simply let it simmer gently over a low heat for a few extra minutes to allow it to reduce and thicken naturally. The sauce will also thicken significantly as it bakes and as it cools.
3. Can I assemble this casserole a day ahead of time? Yes, you can. You can fully assemble the entire casserole in your baking dish, cover it tightly, and store it in the refrigerator for up to 24 hours. You may just need to add about 10-15 minutes to the baking time since you are starting with a cold dish.
4. What other kinds of pasta can I use for this bake? While penne or ziti are fantastic choices, any sturdy pasta shape will work well. Rigatoni, rotini, or even bow-tie pasta would all be delicious in this creamy casserole.
5. Why did my cheese sauce break or look oily? A broken or oily cream sauce is almost always because the heat was too high when the dairy and cheese were added. It is very important to keep the sauce at a gentle simmer and to stir the Parmesan cheese in over a very low heat. Using full-fat heavy cream also creates a more stable sauce that is less likely to break.
