Cheesy Chicken And Broccoli Pasta Bake

One chilly Friday night, I dropped off my daughter at a friend’s sleepover and swung by the grocery store on the way home. I wanted something easy, comforting, and ready before bedtime stories, enter this Cheesy Chicken And Broccoli Pasta Bake.

   

Heading down the pasta aisle, I spotted broccoli on sale and thought: perfect. By the time I got home, my husband was setting the table and the kids were already lining up utensils, drawn by the aroma of garlic sautéing.

I chopped the chicken into bite-sized cubes and tossed them straight into the skillet. Meanwhile, the broccoli got a quick boil, and the pasta started bubbling away. The creamy sauce came together fast: onion, garlic, butter, flour, and warm milk—all whisked into velvety perfection. As I stirred in Parmesan and half-and-half, the kitchen smelled like a cozy Italian trattoria.

When I poured it all into the casserole dish and topped with mozzarella, I could hardly wait. Twenty minutes later, golden cheese bubbled on top and steam curled from the edges. My kids dove right in forks scraping every cheesy corner and my son declared it “better than mac and cheese.”

That night, I thought, this is how simple family favorites are born: comfort, flavor, and zero fuss. From school-night dinners to surprise guests, this bowl feels like a hug for everyone.

  • 2 tsp minced garlic
  • 2 Tbsp all-purpose flour
  • 1 tsp Italian seasoning
  • 1 tsp kosher salt
  • ½ tsp black pepper
  • 1 cup milk
  • 1 cup low-sodium chicken stock
  • ½ cup half-and-half
  • ½ cup grated Parmesan cheese
  • 1½ cups shredded mozzarella cheese

Tools Needed

  • 9×13-inch casserole dish
  • Large pot for pasta and broccoli
  • Large skillet
  • Whisk and wooden spoon
  • Measuring cups and spoons
  • Strainer

Cooking Instructions

Step 1: Prep Oven & Dish
Preheat oven to 400°F. Lightly spray a 9×13 dish with nonstick spray and set aside.

Step 2: Blanch Broccoli
Bring a large pot of water to a boil. Add broccoli and cook 2 minutes. Drain, cool slightly, and chop into bite-sized pieces.

Step 3: Cook Pasta
Using same pot, cook penne per package instructions until al dente. Drain and set aside.

Step 4: Brown Chicken
Heat olive oil in a large skillet over medium-high heat. Add chicken cubes and sauté 6–7 minutes, until lightly browned but not fully cooked. Remove and set aside.

Step 5: Sauté Aromatics
In the same skillet, melt butter. Add diced onion and garlic; cook 3–4 minutes until softened and fragrant.

Step 6: Make the Sauce
Sprinkle flour, Italian seasoning, salt, and pepper into skillet. Stir and cook 1–2 minutes to remove raw flour taste. Whisk in milk and chicken stock, bringing mixture to a simmer until slightly thickened. Stir in half-and-half, Parmesan, broccoli, and chicken, then remove from heat.

Step 7: Assemble Bake
Transfer chicken and sauce mixture to casserole dish. Add drained pasta and stir gently to combine evenly.

Step 8: Top & Bake
Sprinkle mozzarella evenly over top. Bake 15–20 minutes, until cheese is melted and golden.

Step 9: Rest & Serve
Let the bake rest 5 minutes before serving. This helps it settle for clean scoops.

FAQs

1. Can I use rotisserie chicken?
Yes, just skip Step 4 and add cooked chicken during assembly.

2. Is gluten-free an option?
Use gluten-free pasta and a GF flour blend for the sauce.

3. Can I swap broccoli for other veggies?
Sure, cauliflower, peas, or spinach work well in similar quantities.

Add ¼ tsp red pepper flakes or a dash of cayenne to the sauce in Step 6.

Tips & Tricks

Cut chicken into similar-sized cubes for even cooking.

Grate fresh Parmesan for better flavor in sauce.

Use warm milk when adding to whisk smoothly and avoid lumps.

Stir gently when combining pasta to preserve sauce creaminess.

Let bake rest—this makes portioning neater and less runny.

Recipe Variations

Cheesy Chicken & Cauliflower Bake:
Replace broccoli with 4 cups cauliflower florets. Keep rest unchanged.

Creamy Pesto Twist:
Stir in ½ cup basil pesto to sauce before mixing pasta for savory twist.

Spicy Buffalo Chicken Bake:
Toss cooked chicken in buffalo sauce before Step 6 and sprinkle blue cheese instead of Parmesan.
