Ingredients

For the Pasta Bake

• 12 ounces penne pasta – holds the creamy sauce beautifully.
• 2 cups cooked chicken breast, diced or shredded – rotisserie chicken works wonderfully.
• 3 cups broccoli florets – lightly steamed until crisp-tender.
• 2 cups shredded mozzarella cheese – melts into a gooey topping.
• ½ cup grated Parmesan cheese – adds nutty, salty flavor.
• 2 tablespoons butter
• 2 tablespoons olive oil
• 2 cloves garlic, minced
• 2 tablespoons chopped parsley (optional for garnish)

Homemade Alfredo Sauce

• 4 tablespoons butter
• 3 cloves garlic, minced
• 2 cups heavy cream
• 1 cup whole milk
• 1½ cups freshly grated Parmesan cheese
• ½ teaspoon Italian seasoning
• ½ teaspoon onion powder
• ¼ teaspoon black pepper
• ½ teaspoon salt (adjust to taste)
• A pinch of nutmeg (optional for authentic flavor)

Step-by-Step Preparation Method

Step 1: Cook the Pasta – Boil the penne in salted water until al dente. Drain well and set aside.

Step 2: Prepare the Broccoli – Steam or blanch the broccoli for 2–3 minutes, then transfer to ice water. Drain thoroughly.

Step 3: Cook the Garlic – Melt the butter in a saucepan and sauté the minced garlic for about 1 minute until fragrant.

Step 4: Make the Alfredo Sauce – Stir in the heavy cream and milk, then whisk in the Parmesan cheese until melted. Add the seasonings and cook until the sauce is smooth and creamy.

Step 5: Assemble the Casserole – Preheat the oven to 375°F (190°C). Combine the cooked pasta, chicken, broccoli, and Alfredo sauce, then transfer to a greased baking dish. Top with mozzarella and extra Parmesan.

Step 6: Bake – Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden. Broil for 2–3 minutes if you prefer a crispier top.

Step 7: Rest & Serve – Let the pasta bake rest for 5–10 minutes before serving. Garnish with chopped parsley and extra Parmesan, then enjoy warm.
