There are some recipes that earn their place in your regular rotation not because they’re fancy or impressive, but because they’re reliable, comforting, and get dinner on the table fast. This broccoli cheddar chicken pasta bake is one of those recipes. It’s become my go-to on those nights when I need something hearty and satisfying but don’t have the time or energy for anything complicated.
What I love most about this dish is that it delivers all the comfort of a classic pasta bake—creamy cheese sauce, tender pasta, plenty of protein—but comes together in just 30 minutes. No marathon cooking sessions, no complicated techniques. Just straightforward, delicious comfort food that the whole family actually wants to eat.
Why This Recipe Works
The genius of this recipe is in the simplicity. We’re using rotisserie chicken (or leftover cooked chicken) to save time, pre-cut broccoli florets to skip the chopping, and a quick cheese sauce that comes together while the pasta cooks. Everything gets tossed together, topped with more cheese, and baked until bubbly and golden.
I’ve made this recipe countless times—on busy weeknights when I’m exhausted, when I need to use up leftover chicken, when my kids are asking for “something cheesy,” and when I just want comfort food without the fuss. It never disappoints. The pasta is perfectly cooked, the broccoli stays tender-crisp, the chicken is juicy, and that cheese sauce? It’s creamy, rich, and exactly what you want from a pasta bake.
The best part? It’s a complete meal in one dish. You’ve got your protein, your vegetables, your carbs, and plenty of calcium from all that cheese. No need for side dishes (though a simple salad never hurts).
The Complete Recipe
What You’ll Need
Main Ingredients:
- 12 oz penne or rigatoni pasta (about 3 cups dry)
- 3 cups cooked chicken, diced or shredded (rotisserie chicken works perfectly)
- 3 cups broccoli florets (fresh or frozen)
- 2 cups shredded sharp cheddar cheese, divided
- ½ cup shredded mozzarella cheese
For the Cheese Sauce:
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2½ cups whole milk
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon paprika (optional, for color)
Optional Add-Ins:
- ½ cup panko breadcrumbs mixed with 1 tablespoon melted butter (for crispy topping)
- Red pepper flakes for heat
- Fresh herbs like parsley or thyme
Step-by-Step Instructions
Step 1: Cook the Pasta and Broccoli
Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or cooking spray.
Bring a large pot of salted water to a boil. Add the pasta and cook for 2 minutes less than the package directions (it will finish cooking in the oven). During the last 2 minutes of cooking, add the broccoli florets to the pot with the pasta.
Drain the pasta and broccoli together, then set aside.
Step 2: Make the Cheese Sauce
While the pasta is cooking, make the cheese sauce. In a large saucepan, melt the butter over medium heat.
Once the butter is melted and foaming, add the flour. Whisk constantly for about 1 minute—this cooks out the raw flour taste and creates a roux that will thicken your sauce.
Gradually pour in the milk, whisking constantly to prevent lumps. Keep whisking as the mixture heats up. It will start thin, but as it comes to a gentle simmer, it will thicken. This takes about 5-7 minutes.
Once the sauce has thickened enough to coat the back of a spoon, remove it from the heat. Stir in 1½ cups of the cheddar cheese, the garlic powder, onion powder, salt, pepper, and paprika if using. Stir until the cheese is completely melted and the sauce is smooth.
Taste the sauce—it should be well-seasoned and cheesy. Adjust salt and pepper if needed.
Step 3: Combine Everything
Add the cooked pasta, broccoli, and diced chicken to the cheese sauce. Stir everything together until the pasta is well coated with the sauce.
Pour the mixture into your prepared baking dish and spread it out evenly.
Step 4: Top and Bake
Sprinkle the remaining ½ cup of cheddar cheese and the mozzarella cheese over the top. If you’re using the panko breadcrumb topping, sprinkle that over the cheese.
Bake for 15-20 minutes, until the cheese is melted and bubbly and the top is golden brown. If you want extra browning on top, turn on the broiler for the last 2-3 minutes (watch it carefully so it doesn’t burn).
Step 5: Rest and Serve
Let the pasta bake rest for 5 minutes before serving. This allows the sauce to thicken up a bit and makes it easier to serve.
Garnish with fresh parsley if desired, and serve hot.
Tips I’ve Learned Along the Way
Use Rotisserie Chicken: This is the ultimate time-saver. A store-bought rotisserie chicken gives you perfectly cooked, seasoned chicken without any work. Just shred or dice it and you’re done.
Don’t Overcook the Pasta: Since the pasta will continue cooking in the oven, you want to undercook it slightly when you boil it. Aim for 2 minutes less than the package directions.
Fresh vs. Frozen Broccoli: Both work great. If using frozen, don’t thaw it first—just add it to the boiling pasta water. It will thaw and cook at the same time.
Make the Sauce Smooth: The key to a lump-free cheese sauce is whisking constantly when you add the milk to the roux, and making sure the sauce is hot enough for the cheese to melt smoothly.
Cheese Matters: Use good quality, sharp cheddar for the best flavor. Pre-shredded cheese works, but freshly grated melts better and has better flavor. The mozzarella adds stretchiness and helps with that golden, bubbly top.
Make It Ahead: You can assemble this entire dish up to 24 hours in advance. Just cover it tightly and refrigerate. When you’re ready to bake, add an extra 5-10 minutes to the baking time since it’s starting cold.
Leftovers Are Great: This reheats beautifully. Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or in a covered dish in the oven.
Variations I Love:
- Bacon Addition: Add ½ cup of crumbled cooked bacon for extra flavor
- Spicy Version: Add diced jalapeños or red pepper flakes to the sauce
- Veggie Boost: Add mushrooms, bell peppers, or cauliflower along with the broccoli
- Different Cheese: Try Gruyère, fontina, or pepper jack for different flavor profiles
- Whole Wheat Pasta: Use whole wheat pasta for extra fiber
- Gluten-Free: Use gluten-free pasta and substitute cornstarch for the flour in the sauce
