Ingredients

For the Chicken Alfredo Bake

2 cups cooked chicken breast, shredded or cubed
8 ounces (about 225g) penne or fettuccine pasta
2 cups broccoli florets (fresh or frozen, lightly blanched)
2 cups shredded mozzarella cheese
½ cup grated Parmesan cheese
2 tablespoons olive oil or butter
Salt and black pepper to taste

For the Alfredo Sauce

2 tablespoons butter
2 tablespoons all-purpose flour
2 cups heavy cream (or half-and-half for lighter version)
1 cup milk
3 cloves garlic, minced
1 cup grated Parmesan cheese
¼ teaspoon nutmeg (optional)
Salt and pepper to taste

Optional Garnishes

Fresh parsley, chopped
Extra Parmesan cheese
Red chili flakes (for a touch of heat)

Simple Cooking Directions

Cook pasta and broccoli until just tender.
Prepare creamy Alfredo sauce with butter, garlic, cream, and Parmesan.
Combine pasta, chicken, broccoli, and sauce; mix well.
Transfer to a baking dish, top with mozzarella and Parmesan.
Bake until golden, bubbly, and delicious.

Step-by-Step Recipe Preparation Method

Step 1: Cook the Pasta and Broccoli

Bring a large pot of salted water to a boil.
Add pasta and cook 1–2 minutes less than package instructions (it will finish cooking in the oven).
In the last 2 minutes of boiling, add broccoli florets to the same pot.
Drain both pasta and broccoli and set aside.

Step 2: Prepare the Alfredo Sauce

In a medium saucepan, melt butter over medium heat.
Add minced garlic and sauté until fragrant (about 30 seconds).
Stir in flour and cook for 1 minute to remove raw taste.
Slowly whisk in heavy cream and milk until smooth.
Bring to a gentle simmer and cook until slightly thickened, about 3–4 minutes.
Add grated Parmesan, nutmeg, salt, and pepper. Stir until cheese melts and sauce becomes creamy.

Step 3: Combine Everything

Preheat oven to 375°F (190°C).
In a large bowl, combine cooked pasta, chicken, broccoli, and the Alfredo sauce. Toss until evenly coated.
Season with salt and pepper as needed.

Step 4: Assemble the Bake

Lightly grease a 9×13-inch baking dish.
Pour the mixture into the dish and spread evenly.
Sprinkle mozzarella and Parmesan cheese on top.

Step 5: Bake

Bake uncovered for 20–25 minutes, until the cheese is melted and golden brown on top.
For a crispier top, broil for an additional 2–3 minutes.

Step 6: Serve

Let it rest for 5 minutes before serving.
Garnish with fresh parsley and a sprinkle of Parmesan cheese.

How to Serve

Serve your Chicken Alfredo Bake with Broccoli warm, straight from the oven. Pair it with:

Garlic bread or cheesy breadsticks
A side salad (like Caesar or garden salad)
A glass of white wine or sparkling water with lemon

It’s also fantastic as leftovers for lunch the next day!

Additional Recipe Tips

Cook pasta al dente: It continues cooking while baking.
Use fresh Parmesan: It melts better and gives the sauce a smoother texture.
Add depth: Stir in a splash of chicken broth or white wine while making the sauce.
Customize your veggies: Add mushrooms, spinach, or bell peppers for color and nutrition.
For extra creaminess: Mix a bit of cream cheese into the sauce.

Variations

Bacon Alfredo Bake: Add crispy bacon bits for a smoky flavor.
Spicy Alfredo Bake: Add red pepper flakes or chopped jalapeños.
Vegetarian Version: Skip the chicken and add sautéed mushrooms, zucchini, or cauliflower.
Whole Wheat or Gluten-Free: Substitute pasta as per dietary needs.
Low-Fat Option: Use milk instead of cream and reduce cheese slightly.

Freezing and Storage

Refrigeration: Store leftovers in an airtight container for up to 3 days.
Freezing: Wrap the unbaked casserole tightly in foil and freeze for up to 2 months.
To Bake from Frozen: Thaw overnight in the refrigerator, then bake at 375°F (190°C) for 25–30 minutes until hot and bubbly.
Reheating: Warm individual servings in the oven or microwave, adding a splash of milk or cream to keep it moist.

Special Equipment Needed

Large pot (for pasta)
