Ingredients & Equipment

For the Bake:

3 cups cooked pasta (penne, rotini, or fusilli)
2 cups cooked chicken, diced or shredded
3 cups fresh spinach, chopped
2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
2 tablespoons unsalted butter
2 tablespoons all-purpose flour
1 teaspoon garlic powder
2 cups milk (whole or 2%)
1/2 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon black pepper
Pinch of nutmeg (optional)

Optional Toppings:

Extra mozzarella or Parmesan cheese
Fresh parsley, chopped
Crushed breadcrumbs for added crunch

Equipment:

Large mixing bowl
Saucepan for Alfredo sauce
9×13-inch baking dish or equivalent
Whisk for sauce
Spatula and oven mitts

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease the baking dish with butter or cooking spray to prevent sticking.

Step 2: Prepare the Alfredo Sauce

In a medium saucepan, melt butter over medium heat. Add flour and whisk for 1–2 minutes to form a smooth roux. Gradually add milk while whisking continuously to prevent lumps. Stir in garlic powder, onion powder, salt, pepper, and a pinch of nutmeg. Simmer gently for 3–5 minutes until thickened and creamy.

Step 3: Combine Ingredients

In a large mixing bowl, combine cooked pasta, chicken, and chopped spinach. Pour the Alfredo sauce over the mixture and fold gently until all ingredients are evenly coated. Stir in half of the mozzarella cheese for extra creaminess throughout the dish.

Step 4: Assemble the Bake

Transfer the pasta mixture into the prepared baking dish. Sprinkle remaining mozzarella and Parmesan cheese evenly on top. For added texture, sprinkle breadcrumbs over the cheese layer. This step creates a golden, crunchy topping after baking.

Step 5: Bake to Perfection

Place the baking dish in the preheated oven and bake for 20–25 minutes, or until the cheese is fully melted and golden brown. The edges should be bubbly, and the aroma will fill your kitchen with the unmistakable scent of comfort food.

Step 6: Rest and Serve

Allow the casserole to rest for 5–10 minutes before slicing. This resting period helps the sauce thicken slightly and keeps the portions intact. Garnish with fresh parsley for a touch of color. Serve warm and enjoy.

Expert Tips & Troubleshooting

Prevent a watery casserole: Sauté or thoroughly drain spinach to remove excess moisture.
Cheese choices: Mozzarella is creamy and mild; Gruyère or Fontina can add a deeper flavor.
Even cooking: Spread ingredients evenly in the dish to ensure uniform baking.
Make-ahead tip: Assemble the bake in advance and refrigerate for up to 24 hours before baking.
Reheating leftovers: Cover with foil and bake at 350°F (175°C) until warmed through for the best texture.
Check pasta doneness: Slightly undercook pasta before baking so it doesn’t become mushy in the oven.

Variations & Customizations

Add more vegetables: Broccoli, peas, mushrooms, or roasted red peppers enhance flavor and nutrition.
Spicy kick: Add crushed red pepper flakes or a dash of cayenne to the sauce.
Low-carb option: Substitute pasta with zucchini noodles, spaghetti squash, or cauliflower rice.
Protein alternatives: Use turkey, rotisserie chicken, or even shrimp instead of chicken.
Herb infusion: Fresh basil, thyme, or oregano incorporated into the sauce gives added depth.
Cheese swap: Use a combination of cheeses like Fontina, Gouda, or cheddar for different flavors.

Serving & Presentation Ideas

Serve alongside a crisp green salad tossed in lemon vinaigrette to balance richness.
Offer garlic bread, cheesy pull-apart bread, or simple dinner rolls for a complete meal.
Garnish with fresh parsley or extra Parmesan for a polished presentation.
Serve buffet-style in a shallow dish for casual gatherings.
Pair with iced tea, sparkling water, or a lightly flavored lemonade to refresh the palate.

Storage & Make-Ahead Tips

Refrigeration: Store leftovers in an airtight container for up to 3 days. Reheat in the oven or microwave until warmed through.
Freezing: Assemble but do not bake. Wrap tightly and freeze for up to 2 months. Thaw overnight and bake as directed.
Meal prep: Cook chicken and pasta ahead of time, then assemble the casserole before baking to save time on busy nights.
