Creamy Broccoli and Chicken Pasta Bake

 There are certain dishes that feel like a warm hug on a plate—and this Creamy Broccoli and Chicken Pasta Bake is exactly that. Tender pasta, juicy shredded chicken, vibrant broccoli florets, and a lusciously creamy, cheesy sauce all come together under a golden, buttery breadcrumb topping. It's the kind of meal that fills your kitchen with the most inviting aroma and brings everyone to the table with anticipation.

I first made this casserole on a chilly evening when I needed something hearty, quick, and guaranteed to please both kids and adults. It delivered on every front—creamy, satisfying, and packed with hidden veggies. Now, it's a regular in my dinner rotation, especially on busy weeknights when I need a meal that feels special but requires minimal fuss.

The best part? It all comes together in one baking dish, uses pantry staples, and is endlessly adaptable. Let's get cooking!

Ingredients

For the Pasta Bake

Ingredient Amount Notes

Uncooked pasta (penne, rotini, or similar) 2 cups Choose a shape that catches the sauce

Cooked chicken, shredded or diced 2 cups Rotisserie chicken works perfectly

Broccoli florets 2 cups Fresh or frozen (thawed if frozen)

Grated cheddar cheese 1 cup Sharp cheddar gives the best flavor

Heavy cream (or half-and-half) 1 cup For ultimate creaminess

Chicken broth 1 cup Low-sodium recommended

Garlic powder 1 teaspoon For savory depth

Onion powder 1 teaspoon Adds subtle sweetness

Salt ½ teaspoon Adjust to taste

Black pepper ¼ teaspoon Freshly ground preferred

Paprika (optional) ½ teaspoon For a hint of smokiness and color

Grated Parmesan cheese ¼ cup Adds nutty, salty richness

For the Crispy Topping

Ingredient Amount Notes

Breadcrumbs ½ cup Panko gives extra crunch

Melted butter 2 tablespoons For a golden, buttery finish

Grated Parmesan cheese ¼ cup For flavor and browning

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 350°F (175°C) . Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.

2. Cook the Pasta

Cook the pasta according to package instructions until al dente—firm to the bite. Drain well and set aside.

Pro tip: Undercook the pasta by about 1 minute, as it will continue to cook and absorb sauce in the oven. This prevents a mushy casserole.

3. Prepare the Broccoli

If using fresh broccoli, steam or blanch it in boiling water for 2–3 minutes until bright green and just tender. Drain and set aside.

If using frozen broccoli, simply thaw it completely and pat dry with paper towels to remove excess moisture.

Pro tip: Removing excess moisture from the broccoli prevents a watery casserole and keeps the sauce luxuriously thick.

4. Make the Creamy Sauce

In a very large mixing bowl, whisk together the heavy cream, chicken broth, garlic powder, onion powder, salt, pepper, and paprika (if using). Stir until smooth and well combined.

5. Combine Everything

Add the cooked pasta, shredded chicken, and prepared broccoli to the bowl with the sauce. Gently fold everything together until the pasta, chicken, and broccoli are evenly coated.

Then, add the cheddar cheese and Parmesan cheese and stir until the cheese is fully incorporated into the creamy mixture.

6. Transfer to Baking Dish

Pour the entire mixture into your greased baking dish. Spread it into an even layer with a spatula.

7. Prepare the Topping

In a small bowl, combine the breadcrumbs, melted butter, and Parmesan cheese until the crumbs are evenly moistened. Sprinkle this mixture generously and evenly over the top of the casserole.

8. Bake to Golden Perfection

Place the dish on the center rack of your preheated oven. Bake, uncovered, for 25–30 minutes, or until the casserole is bubbling around the edges, the sauce is thickened, and the topping is golden brown and crisp.

Visual cue: The cheese should be melted and slightly caramelized, and you'll see gentle bubbles breaking through the topping.

9. Rest and Serve

Remove from the oven and let the casserole rest for 5–10 minutes before serving. This resting time allows the sauce to set, making it easier to scoop clean, beautiful portions.

Variations and Substitutions

Swap the protein: Use leftover turkey, shredded rotisserie chicken, or even cooked sausage.

Add extra veggies: Sautéed mushrooms, spinach, bell peppers, or peas would be wonderful additions.

Make it spicy: Add a pinch of red pepper flakes or a dash of hot sauce to the sauce.

Lighter version: Substitute the cream with half-and-half or whole milk (reduce the broth slightly to maintain thickness), and use a reduced-fat cheese blend.

Gluten-free: Use gluten-free pasta and gluten-free breadcrumbs.

Add a roux: For an even thicker, richer sauce, melt 2 tablespoons of butter in a saucepan, whisk in 2 tablespoons of flour, cook for 1 minute, then gradually whisk in the cream and broth before combining with the other ingredients.

What to Serve With This Pasta Bake

This casserole is a complete meal on its own, but it pairs beautifully with:

A crisp green salad tossed with a light vinaigrette.

Garlic bread or a warm, crusty baguette.

Roasted or steamed green beans or asparagus on the side.

A glass of crisp white wine, like a Sauvignon Blanc or Chardonnay.

Storage and Reheating Tips

Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days. The flavors actually deepen overnight!

Freeze: This casserole freezes beautifully. Assemble completely (without baking), cover tightly, and freeze for up to 3 months. Thaw overnight in the fridge, then bake as directed, adding 10–15 minutes to the cooking time.

Reheat: Warm individual portions in the microwave in 30-second intervals. For larger portions, reheat in a 350°F oven covered with foil until heated through (about 15 minutes), then uncover for the last 5 minutes to re-crisp the topping.
