On busy weeknights, you don’t want to be fussing around the kitchen when everyone’s starving. That’s why this broccoli dish is perfect. It’s full of creamy Alfredo sauce, tender chunks of boneless skinless chicken breast, and lots of fresh green broccoli. It makes a delicious weeknight dinner that’s a complete meal and a total crowd-pleaser.

This was inspired by my homemade Alfredo sauce on this site, and pairs well with a Caesar salad and warm garlic bread or my simple garlic crostini

Ingredients

  • Dried Pasta– I use ziti rigati or traditional ziti, but you can use your favorite pasta or whatever you have on hand.
  • Broccoli Florets – Fresh or frozen broccoli works in this recipe. I use about 16 oz of florets, which is roughly 2 large broccoli crowns. It doesn’t have to be exact.
  • Alfredo Sauce– Use your favorite brand or homemade alfredo sauce. I love using my alfredo sauce without heavy cream for this pasta bake.
  • Cooked Chicken – You can use whatever you have on hand. I use diced chicken breasts and chunks of rotisserie chicken. The tender chicken adds a nice contrast to the crisp broccoli and the creamy sauce.
  • Shredded mozzarella cheese. You can use an Italian blend too if you prefer!

Instructions

Step 1: Preheat the oven to 400 degrees F and move the oven rack to the middle level.

Step 2: Boil a large pot of salted water and add the dried pasta. Cook to al dente per the package directions.

Add fresh broccoli florets to the pasta water during the last two minutes of cooking. The broccoli should be bright green and still have a little snap to it. 

Note: If using frozen broccoli, skip the cooking step but instead thaw and drain off excess moisture.

Step 3: While the pasta is cooking, warm the alfredo sauce over low heat until heated through.

Hint: Heating the Alfredo sauce will make sure all the ingredients are warm when they go into the oven. This decreases baking time and ensures the cheese browns without overcooking the broccoli and ziti.

Step 7: Bake at 400F for 30-35 minutes until the alfredo sauce is bubbling and the cheese is melty and golden brown.

Substitutions

  • Chicken Breasts- swap the chicken for sausage, cooked shrimp, or even leftover turkey (this recipe is great for using Thanksgiving leftovers).
  • Alfredo Sauce – Any creamy white sauce will work for this recipe. You can use a basic white sauce like a bechamel or you can use a cheddar cheese sauce in place of alfredo. See my baked cheddar broccoli recipe for the cheese sauce.
  • Vegetarian – omit the chicken and use extra broccoli or cooked mushrooms in its place.

Variations

  • Bump up the spice -Add red pepper flakes and extra black pepper to the alfredo sauce to make it spicy. 
  • Add Bacon – Stir crispy pieces of bacon into the chicken and broccoli mixture.
  • Veg it up – Add diced tomatoes, artichoke hearts, or peas for extra veggies.

Equipment

Storage

Leftovers can be stored covered in plastic wrap or transferred to an airtight container and refrigerated for up to three days.

Reheat leftovers uncovered in a 350-degree F oven until heated through or in the microwave for a quick lunch.

Pro Tips and Tricks

For The Best Chicken Broccoli Alfredo

  • Trim broccoli florets into similar sizes so that they cook evenly.
  • Make sure the Alfredo, broccoli, and pasta are warm when they go into the preheated oven. This will shorten the cooking time.
  • Add a splash of chicken broth or extra Alfredo sauce if the casserole is looking dry.

FAQs

If you’re using alfredo sauce from a jar, you can boost the flavor by adding fresh or roasted garlic cloves, Italian seasoning, or garlic powder. To add even more flavor to the cream sauce, add extra grated parmesan cheese or a few spoonfuls of pesto.

Yes. You’ll just need to thaw the broccoli first and then drain off any liquid. It’s already par-cooked, so it can be added along with the other prepared ingredients in the mixing bowl.
