Step 1: Cook pasta and broccoli

Bring a large pot of water to a boil. Add fusilli and cook until al dente, according to package directions. In the last 2 minutes of cooking, add the chopped broccoli to the boiling water. Before draining, reserve 1 cup of pasta water. Drain and set aside.

Step 2: Preheat Oven and Cook chicken

While pasta cooks, preheat the oven to 350. Cube the chicken breast then heat a large skillet over medium-high heat, add a drizzle of oil, and pan-fry chicken for 7–9 minutes, until golden and cooked through. Remove and set aside.

Step 3: Make the sauce

In the same skillet, melt butter. Whisk in the reserved pasta water until combined. Add milk, bouillon, garlic powder, and ¾ cup of Parmesan. Stir until heated through (the sauce will be light, not super thick).

Step 4: Combine everything

Add the pasta, broccoli, chicken, and sauce back into the large pot you cooked the pasta in. Stir until everything is evenly coated.

Step 5: Bake

Transfer pasta mixture into a 13×9 baking dish. Top with mozzarella and the remaining Parmesan. Bake for 15 minutes until warmed through. For a crispier top, broil for 3–5 minutes.
