How to Make Chicken & Broccoli Alfredo Bake Recipe
Step 1: Preheat and Prepare Pasta
Get your oven heating to 375°F (190°C) so it’s ready when the dish is assembled. Cook the penne pasta until just al dente for perfect bite, and in the last few minutes, add your broccoli florets to blanch. This technique keeps the greens vibrant and crisp tender, which balances the creamy sauce wonderfully.
Step 2: Combine the Filling Ingredients
In a large bowl, toss together the cooked chicken, pasta, and broccoli with the Alfredo sauce. Stir in the Italian seasoning and grated Parmesan to infuse the mixture with savory layers. Don’t forget to season with salt and pepper for that final flavor boost—it’s all about harmony here.
Step 3: Transfer and Top
Grease your 9×13-inch baking dish to prevent sticking, then pour in the creamy chicken and broccoli mixture. Evenly sprinkle the shredded mozzarella cheese over the top—it will melt into a beautifully golden crust that’s irresistible.
Step 4: Bake to Perfection
Pop the dish into the oven for 20 to 25 minutes. You want the bake bubbling hot and the cheese on top melted and golden. If you love a richer brown finish, broil for 1 or 2 minutes but be vigilant to avoid burning.
Step 5: Rest and Serve
Let the bake cool for about 5 minutes—it helps the sauce thicken slightly and makes it easier to serve without losing its luscious texture. For a fresh pop of color, sprinkle with chopped parsley before serving warm and enjoy every comforting bite.
How to Serve Chicken & Broccoli Alfredo Bake Recipe

Garnishes
Simple garnishes like freshly chopped parsley or a light drizzle of extra virgin olive oil can elevate the presentation while adding a touch of freshness. A sprinkle of crushed red pepper flakes also works wonders if you want a little heat.
Side Dishes
This creamy Chicken & Broccoli Alfredo Bake Recipe pairs beautifully with a crisp green salad tossed in a tangy vinaigrette. Garlic bread or crusty French bread rounds out the meal perfectly, soaking up every bit of that luscious sauce.
Creative Ways to Present
Serve this bake family-style in the casserole dish straight from the oven for a warm and inviting vibe. For a more elegant touch, plate individual servings with a lemon wedge on the side to brighten the creamy richness just before eating.
Make Ahead and Storage
Storing Leftovers
After enjoying your Chicken & Broccoli Alfredo Bake Recipe, store any leftovers in an airtight container in the refrigerator. It will keep well for up to 3 days and remains just as comforting and flavorful when reheated.
Freezing
This dish freezes wonderfully. Before baking, assemble the casserole, cover it tightly with foil, and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge, then bake as directed for a hassle-free meal.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until warmed through and the cheese bubbles again. Using the oven keeps the bake creamy and prevents it from drying out like a microwave might.
FAQs
Can I use a different type of pasta?
Absolutely! While penne works great for holding the sauce, rigatoni, rotini, or even farfalle can be delicious alternatives. Just cook them according to package directions until al dente.
Is there a way to make this dish healthier?
You can swap the Alfredo sauce for a lighter homemade version using cauliflower or Greek yogurt. Using part-skim mozzarella and lean chicken breast will also cut calories without sacrificing taste.
Can I use frozen broccoli?
Yes, frozen broccoli works well if you steam or blanch it first to remove excess moisture. This helps avoid sogginess in the bake and keeps the texture just right.
What if I don’t have cooked chicken on hand?
No problem! You can quickly cook raw chicken breasts in a skillet with a bit of seasoning, then shred or dice before mixing. Leftover rotisserie chicken also makes a fantastic shortcut.
Can this recipe be made dairy-free?
Definitely. Substitute dairy-free Alfredo sauce and vegan cheese alternatives to keep it creamy without dairy. Just ensure the cheese melts nicely for that golden topping.
