Ingredients

  

• 12 ounces short pasta (penne, rigatoni, or ziti)
• 2 cups cooked chicken, shredded or cubed (rotisserie works well)
• 2 tablespoons olive oil (if cooking raw chicken)
• 3 tablespoons unsalted butter
• 3 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 2 cups whole milk (or 1½ cups milk + ½ cup cream)
• 1 cup low-sodium chicken broth
• 1 cup freshly grated Parmesan cheese, plus more for topping
• 1 cup shredded mozzarella cheese
• 1/2 teaspoon kosher salt, or to taste
• 1/2 teaspoon black pepper
• 1/2 teaspoon Italian seasoning (optional)
• 1/4 teaspoon crushed red pepper flakes (optional, for gentle heat)
• 1 tablespoon fresh lemon juice (optional, brightens the sauce)
• 2 tablespoons chopped fresh parsley, for garnish

Method

 

1. Preheat and prep: Heat the oven to 375°F (190°C).

   Grease a 9×13-inch baking dish. If your chicken isn’t cooked, season with salt and pepper and sauté in olive oil over medium heat until just cooked through. Let cool, then chop or shred.

2. Cook the pasta: Bring a large pot of salted water to a boil.

   Cook pasta until just shy of al dente (1–2 minutes less than package time). Drain and set aside.

3. Start the sauce: In a large skillet or pot, melt the butter over medium heat. Add minced garlic and cook for about 30 seconds, stirring often.
4. Build the roux: Sprinkle in the flour and whisk for 1–2 minutes until the mixture bubbles and smells toasty.

   Don’t let it brown.

5. Add liquids: Slowly whisk in the milk and chicken broth. Keep whisking until smooth, then simmer for 3–4 minutes until slightly thickened.
6. Cheese and season: Lower the heat. Stir in Parmesan until melted and smooth.

   Season with salt, pepper, Italian seasoning, and red pepper flakes. Add lemon juice if using.

7. Combine: Stir the cooked chicken and pasta into the sauce. If it looks very thick, add a splash of warm water or broth—remember it will thicken more in the oven.
8. Assemble: Transfer the mixture to the baking dish.

   Sprinkle mozzarella and a little extra Parmesan evenly over the top.

9. Bake: Bake for 18–22 minutes, until the edges bubble and the top is melted and lightly golden. For more color, broil for 1–2 minutes, watching closely.
10. Rest and serve: Let it sit for 5–10 minutes so the sauce settles. Garnish with parsley.

    Taste and finish with a pinch of salt or a squeeze of lemon if needed.

Keeping It Fresh

• Storage: Cool completely, then cover and refrigerate for up to 4 days.
• Reheat: Warm individual portions in the microwave with a splash of milk or broth to loosen the sauce. For the whole dish, cover with foil and reheat at 325°F until hot.
• Freezing: Assemble without baking, wrap tightly, and freeze for up to 2 months. Thaw in the fridge overnight, then bake as directed, adding 10–15 minutes if needed.
• Avoid drying out: If the pasta seems tight after storage, stir in a little warm milk or broth before reheating.

Why This is Good for You

Comfort food counts, especially when you build it with simple, real ingredients.

You’re getting lean protein from the chicken and a dose of calcium from the dairy. Pair it with a salad or steamed vegetables to round out the meal with fiber and color. And because it’s filling, smaller portions go a long way, which helps with balance.

What Not to Do

• Don’t overcook the pasta: It keeps cooking in the oven; start it slightly under.
• Don’t use pre-shredded Parmesan: It often has anti-caking agents that affect melting and flavor.

  Freshly grated is worth it.

• Don’t skip seasoning: Taste the sauce before baking. Salt, pepper, and acid make the flavors pop.
• Don’t bake it dry: If the mixture looks tight, add a splash of liquid before it goes in the oven.
• Don’t crank the heat: High oven temps can split the sauce and toughen the chicken.

Recipe Variations

• Veggie-loaded: Stir in sautéed mushrooms, spinach, peas, or roasted broccoli before baking.
• Bacon twist: Add crisp bacon or pancetta for smoky depth. Use some of the drippings for the roux if you like.
• Lightened up: Use 2% milk and half the mozzarella.

  Add extra vegetables to keep it satisfying.

• Gluten-free: Choose gluten-free pasta and swap the flour for a 1:1 gluten-free blend or use cornstarch.
• Spicy kick: Add a teaspoon of Calabrian chili paste or more red pepper flakes.
• Pesto Alfredo: Stir 2–3 tablespoons of pesto into the sauce for herbiness.
• Extra protein: Mix in cooked Italian sausage or swap chicken for shrimp (reduce bake time slightly).
• Cheese swap: Try fontina or provolone for meltiness, or a little Pecorino Romano for salty bite.

FAQ

Can I use jarred Alfredo sauce?

Yes, in a pinch. You’ll need about 3 cups. Warm it with a splash of broth or milk to reach a pourable consistency, then proceed with the recipe.

For best flavor, add fresh garlic and a handful of Parmesan.

What pasta shape works best?

Short, sturdy shapes like penne, rigatoni, or ziti hold sauce well and bake evenly. Avoid very small shapes that can get mushy, and avoid long noodles which tangle and dry out.

How do I keep the sauce from curdling?

Keep the heat moderate, whisk constantly when adding milk, and avoid boiling once the cheese is in. Bake at 375°F and don’t overbake.

If it looks too thick before baking, loosen with a splash of liquid.

Can I make it ahead?

Yes. Assemble up to a day in advance, cover, and refrigerate. Let it sit at room temperature for 20–30 minutes, then bake.

You may need an extra 10 minutes to heat through.

What if I don’t have chicken broth?

Use water with 1/2 teaspoon extra salt and a little more Parmesan. The flavor won’t be as deep, but it will still be tasty. You can also use vegetable broth.

Is rotisserie chicken okay?

Absolutely.

It’s flavorful and saves time. Remove the skin if you prefer a lighter bake, and chop the meat into bite-size pieces.

How can I add veggies without making it watery?

Cook them first to remove moisture. Sauté mushrooms, drain spinach well, or roast broccoli and peppers.

Fold them in just before baking.

Can I make this without flour?

Yes. Use 1 tablespoon of cornstarch whisked into cold milk, then add to the melted butter and garlic. Simmer until thickened before adding cheese.
