Simple Instructions for Making Broccoli Chicken Alfredo
The method is straightforward and takes only a few minutes to assemble before baking.
-
Layer the cooked chicken and blanched broccoli, mix Alfredo sauce with milk and pour over, then top with cheese. -
Bake at 375°F for 25–30 minutes until bubbling and golden. -
Serve over pasta, rice, or with your favorite sides.
Step-by-Step Directions
- Preheat the oven to 375°F (190°C).
- Blanch the broccoli: bring a pot of salted water to a boil, add trimmed broccoli crowns and cook just until bright green (a few minutes). Drain and immediately rinse under cold water or plunge into an ice bath to stop cooking.
- Place the diced cooked chicken in the bottom of an 8- or 9-inch square baking dish. Add the blanched broccoli on top.
- Stir the Alfredo sauce and milk together until smooth. Pour the sauce over the chicken and broccoli, then stir gently in the dish so everything is evenly coated.
- Sprinkle the grated Parmesan evenly over the top.
- Bake uncovered for 25–30 minutes, or until the sauce is bubbling and the cheese is lightly browned. Let rest a few minutes before serving—the sauce will thicken as it cools.
Helpful Tips
- Use pre-cooked chicken such as rotisserie or leftover baked chicken to save time.
- Jarred Alfredo sauce keeps this recipe quick and convenient; thin it slightly with milk to reach the desired consistency.
- Stir the layers gently in the dish after pouring the sauce so the chicken and broccoli are evenly coated before adding the cheese.
- Don’t overcook the broccoli during blanching. Stop the cooking process with cold water to keep it bright and slightly crisp.
