Cheesy Chicken Broccoli Pasta Bake (Print Version)

# Ingredients:

01 - 3 boneless, skinless chicken breasts, cut into bite-sized pieces
02 - 2 large heads of fresh broccoli, cut into florets
03 - 1 pound penne pasta
04 - 1 tablespoon olive oil
05 - 2 tablespoons unsalted butter
06 - 1 medium yellow onion, finely diced
07 - 2 teaspoons fresh garlic, minced
08 - 2 tablespoons all-purpose flour
09 - 1 teaspoon Italian herb seasoning
10 - 1 teaspoon kosher salt
11 - ½ teaspoon freshly ground black pepper
12 - 1 cup whole milk
13 - 1 cup low-sodium chicken broth
14 - ½ cup half-and-half cream
15 - ½ cup freshly grated Parmesan cheese
16 - 1½ cups shredded mozzarella cheese

# Instructions:

01 - Preheat your oven to 400°F and generously spray a 9x13 inch baking dish with cooking spray. Set aside while you prepare the other components.
02 - Bring a large pot of salted water to a boil. Add broccoli florets and cook for just 2 minutes until bright green and slightly tender. Drain immediately and set aside.
03 - In the same pot, cook penne pasta according to package directions until al dente. Drain well and set aside. Don't overcook since it will bake more in the oven.
04 - Heat olive oil in a large skillet over medium-high heat. Add cubed chicken and cook for 6-7 minutes, stirring occasionally, until golden brown and cooked through. Remove chicken and set aside.
05 - In the same skillet, melt butter over medium heat. Add diced onion and minced garlic, cooking for 3-4 minutes until onion is softened and fragrant.
06 - Sprinkle flour, Italian seasoning, salt, and pepper over the onion mixture. Cook for 1-2 minutes, stirring constantly. Gradually whisk in milk and chicken broth, bringing to a gentle boil.
07 - Once the sauce thickens slightly, stir in half-and-half, cooked chicken, and blanched broccoli. Let everything heat through for 2-3 minutes.
08 - Transfer the chicken and broccoli mixture to your prepared baking dish. Add the cooked pasta and gently mix everything together. Sprinkle both cheeses evenly over the top.
09 - Bake for 15-20 minutes until the cheese is melted, golden brown, and the edges are bubbling. Let cool for 5 minutes before serving.

# Notes:

01 - Don't overcook the broccoli - it should still have a slight bite
02 - Cook pasta just until al dente since it continues cooking in the oven
03 - Make sure to brown the chicken well for extra flavor
04 - Freshly grated cheese melts much better than pre-shredded
05 - This casserole reheats beautifully for leftovers
