List of ingredients

12 ounces penne pasta – cooked in salted water per package directions.
3 cups diced cooked chicken – roasted, shredded, or rotisserie.
3 tablespoons butter – used to create the roux.
2 tablespoons flour – thickens the sauce.
1 teaspoon minced garlic – adds aromatic flavor.
2 cups whole milk – provides the liquid base.
1 cup heavy cream – adds richness and stability.
3/4 cup grated parmesan cheese – adds a salty, sharp flavor.
2 cups shredded mozzarella cheese – divided for the sauce and topping.
Salt and pepper – adjusted to taste.
Cooking spray – prevents the pasta from sticking to the dish.
1 tablespoon parsley – chopped for garnish.

step-by-step instructions

Prepare Oven and Pan: Preheat your oven to 375 degrees. Lightly coat a 3 quart baking dish with cooking spray to ensure easy release.
Create the Roux: Melt the butter in a large pan over medium heat. Add the minced garlic and cook for 30 seconds, then whisk in the flour and cook for 1 minute to remove the raw flour taste.
Thicken the Base: Pour in the milk and heavy cream. Simmer the mixture while whisking constantly until the sauce has just thickened.
Incorporate Cheeses: Stir in the parmesan cheese and 1/2 cup of the shredded mozzarella. Add salt and pepper, then continue stirring until the cheese is fully melted and smooth.
Combine Ingredients: Place the cooked pasta and diced chicken in a large mixing bowl. Pour the prepared cheese sauce over the top and toss until every piece is evenly coated.
Assemble for Baking: Transfer the pasta mixture into the prepared baking dish. Spread the remaining mozzarella cheese evenly across the top.
Bake: Bake uncovered for 20 minutes. The dish is ready when the pasta is bubbly and the cheese has started to brown.
Finish: Remove from the oven and sprinkle with chopped parsley before serving.

Techniques for Better Results

Use Freshly Grated Cheese

Grate your mozzarella and parmesan from a block rather than using pre-shredded bags. Pre-shredded cheeses contain cellulose or anti-caking agents that prevent them from melting smoothly into the sauce.

Cook Pasta Al Dente

Boil the penne for 1-2 minutes less than the package instructions. Since the pasta continues to cook in the oven, starting with al dente noodles prevents them from becoming mushy.

Maintain Constant Whisking

Whisk the milk and cream continuously while simmering. This prevents the flour from clumping and ensures the sauce remains an emulsion without separating.

Use a Large Mixing Bowl

Tossing the pasta and chicken in a separate bowl before transferring to the baking dish ensures the sauce is distributed evenly. This prevents dry spots in the final baked product.

Ingredient Substitutions and Variations

Alternative Pasta Shapes

While penne is standard, you can use rigatoni, fusilli, or farfalle. These short shapes have ridges or folds that capture the thick Alfredo sauce more effectively than long noodles.

Adding Fresh Vegetables

Include sautéed mushrooms, fresh spinach, or sun-dried tomatoes for extra nutrients. Sauté vegetables separately first to remove excess moisture, which prevents the sauce from becoming watery.

Protein Swaps

Replace the chicken with 3/4 cup of cooked shrimp for a seafood version. You can also use a mix of both proteins to create a combination platter.

Alternative Cheese Options

Substitute the parmesan with pecorino romano or asiago cheese. These options provide a sharper or nuttier profile compared to standard parmesan.

Herbal Adjustments

Swap the parsley for fresh basil, chives, or thyme. Basil adds a traditional Italian sweetness, while chives provide a mild onion flavor.

Using Stuffed Pasta

Replace penne with cheese ravioli or tortellini. This increases the overall cheese content and changes the texture of the bake.

Preparation and Storage Advice

Advance Sauce Preparation

The Alfredo sauce can be made up to two days in advance. Store it in an airtight container in the refrigerator and reheat it gently on the stove before mixing with the pasta.

Refrigerating Leftovers

Store leftover pasta bake in a sealed container for up to three days. Ensure the food is cooled slightly before sealing to prevent excess condensation from forming.

Proper Reheating Method

Cover the leftovers with aluminum foil to retain moisture. Bake at 350 degrees Fahrenheit until the internal temperature reaches 165 degrees Fahrenheit, which typically takes about 45 minutes.

Preventing Sauce Separation

When reheating in a microwave, add a tablespoon of milk or water to the pasta. Stir halfway through the heating process to re-incorporate the fats and liquids.

Troubleshooting Common Issues

Sauce is Too Thick

If the sauce becomes too dense during the simmering stage, whisk in a small amount of milk. Add the liquid one tablespoon at a time until the desired consistency is reached.

Sauce is Too Thin

Allow the sauce to simmer for an additional 2-3 minutes over medium heat. The constant evaporation of liquid will concentrate the roux and thicken the texture.

Cheese is Not Browning

If the 20-minute bake time passes and the cheese is not brown, turn on the broiler for 1-2 minutes. Monitor the dish closely to prevent the cheese from burning.

Pasta is Too Dry After Baking

This usually happens if the pasta was overcooked before baking. To fix this, ensure you use a slightly higher ratio of sauce to pasta in future attempts.

Frequently Asked Questions

What is the best chicken to use for this bake?

Roasted chicken, shredded slow-cooker chicken, or store-bought rotisserie chicken work best. Ensure the chicken is fully cooked and diced into uniform pieces for even distribution.

Can I use a different milk?

Whole milk is recommended for the richest flavor, but 2% milk can be used. Avoid using skim milk as it may result in a thinner sauce that does not bind as well.

Can I use a different size baking dish?

A 3 quart dish is ideal for this volume. If using a larger pan, the sauce may spread thinner and evaporate faster, potentially leading to a drier bake.

Why does the recipe use both milk and cream?

The milk provides the volume and base, while the heavy cream adds fat for a silkier mouthfeel. This combination balances richness with a manageable consistency.

Do I need to salt the pasta water?

Yes, salting the water is the only chance to season the pasta itself. This ensures the dish is flavorful from the inside out, not just from the sauce.
