How to Make Chicken & Broccoli Alfredo Bake
Step 1: Boil Pasta and Broccoli
Start by getting your pasta water boiling with a generous pinch of salt. Cook the penne according to package directions, and don’t forget to toss the broccoli florets in for the last two minutes. This clever trick means your veggies are perfectly cooked alongside your pasta, saving you time and dishes. Once both are tender, drain and set aside—they’ll be ready to soak up all that creamy Alfredo goodness.
Step 2: Sauté the Chicken
While the pasta cooks, heat olive oil in a large skillet over medium-high heat. Season your chicken pieces with garlic powder, salt, and pepper, then sizzle them in the pan until golden and cooked through, about 6 to 8 minutes. Don’t rush this step—the browning adds heaps of flavor! Once done, transfer the chicken to a plate so you can move on to making the luscious sauce.
Step 3: Prepare the Alfredo Sauce
In the same skillet (no need to wash, those brown bits mean flavor!), melt the butter and gently sauté the minced garlic for about a minute. Sprinkle in the flour, whisking for a minute or two until it forms a smooth paste. Now, slowly pour in the milk and cream, whisking constantly to keep the sauce silky. Let it simmer until just thickened, then stir in the Parmesan and Italian seasoning for that classic Alfredo magic.
Step 4: Combine Everything
It’s time to bring it all together! Add the cooked pasta, broccoli, and chicken to your skillet, tossing everything so each piece is coated in that dreamy sauce. The mixture should be creamy but not soupy—if it looks a little thick, a splash of milk will loosen it up.
Step 5: Assemble and Bake
Transfer the mixture to a greased 9×13-inch baking dish, spreading it out evenly. Sprinkle the shredded mozzarella generously over the top for that irresistible, melty finish. Bake uncovered in a preheated 375°F oven for about 20 minutes, or until the top is bubbly and golden. The aroma will have everyone circling the kitchen!
Step 6: Garnish and Serve
Once your Chicken & Broccoli Alfredo Bake is hot and gorgeous, sprinkle fresh parsley over the top for a burst of color and freshness. Serve it piping hot and watch those plates get scraped clean!
How to Serve Chicken & Broccoli Alfredo Bake

Garnishes
A final flourish of chopped fresh parsley not only adds a pop of color but also a hint of herbal freshness that balances the rich, creamy flavors. For a little extra flair, try a dusting of grated Parmesan or a sprinkle of red pepper flakes if you like a gentle kick. If you’re feeling fancy, a drizzle of good olive oil just before serving can make the Chicken & Broccoli Alfredo Bake shine even brighter.
Side Dishes
This casserole is hearty enough to stand alone, but it pairs beautifully with a crisp green salad or simple garlic bread to help soak up every last bit of sauce. Roasted asparagus, sautéed spinach, or even a fresh tomato salad work well to lighten up the meal and round out the plate.
Creative Ways to Present
If you’re entertaining, consider serving the Chicken & Broccoli Alfredo Bake in individual ramekins for a fun, personalized touch. For potlucks or buffets, keep it in a warm slow cooker set to low so guests can help themselves. Leftovers can also be scooped into bell pepper halves and baked for a second meal that feels brand new!
Make Ahead and Storage
Storing Leftovers
Let the Chicken & Broccoli Alfredo Bake cool to room temperature before covering and refrigerating. It keeps well for up to 3 days in an airtight container, making it perfect for lunchboxes or easy reheating on busy nights.
Freezing
To freeze, assemble the casserole but skip baking and the fresh parsley garnish. Wrap tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge before baking as directed, adding a few extra minutes to ensure it’s heated through.
Reheating
For best results, reheat leftovers in a 350°F oven, covered with foil to prevent drying out. A splash of milk can revive the sauce if it seems a bit thick. Microwave reheating works in a pinch—just be sure to stir halfway through for even warmth.
