Broccoli and Chicken Alfredo Casserole

Cook this broccoli and chicken alfredo casserole for a delicious weeknight dinner for the whole family. It’s comforting, cheesy, creamy, and will satisfy even picky eaters.

The homemade version of this restaurant-style dish is so much better! My trick to make the chicken alfredo bake faster is to use a good store-bought Alfredo sauce and leftover chicken.

This oh-so-creamy pasta bake is kids and husband-approved and makes great leftovers so you don’t have to worry about lunch tomorrow.

I have more pasta recipes with broccoli, like this simple 30-minute Broccoli pasta and Grilled Chicken Broccoli Tortellini.

Why You’ll Love This Recipe

• The perfect way to use leftover rotisserie chicken.
• Super easy. The whole dish comes together without any olive oil and you don’t have to melt butter. You don’t need a mixer either – it is almost a one-pot meal.
• Family-friendly and works for meal prep.

Ingredients Notes

You will find exact quantities and cooking steps on the recipe card at the end of the page.

• Cooked chicken. Shred it or dice it into bite-sized pieces. You can use leftover cooked chicken or buy rotisserie chicken or shredded chicken from the store.
• Broccoli florets. You can use fresh or frozen broccoli.
• Pasta (penne pasta or rotini). You need sturdy pasta types so they don’t get mushy while baking. To keep this low-carb you can skip the pasta, but with pasta, it makes a complete meal.
• Alfredo sauce (store-bought or homemade alfredo sauce).
• Cheese mixture: Shredded mozzarella cheese and Grated Parmesan cheese or shredded parmesan cheese. Make sure for both cheeses to buy whole block (or balls) and shred/grate at home. Commercial mixes have additives that don’t melt well, and the lumps in our topping are the last thing we want.
• Seasoning: garlic powder, onion powder, salt and black pepper, to taste

Kitchen Equipment

• 9×13 baking dish or casserole dish
• Pot and colander
• Cooking spray
• Microplane
• Plastic wrap or aluminum foil to cover the leftovers

How To Make Chicken Broccoli Alfredo Bake

1: Boil Pasta And Broccoli

1. Preheat oven to 350°F (175°C).
2. Prep a 9×13 baking dish with cooking oil. Set aside.
3. Cook the pasta according to package directions. Drain and set aside.
4. If using fresh broccoli florets, blanch them in the boiling pasta water for 2-3 minutes, then drain. If you are using frozen – thaw it first.

2: Combine All The Ingredients

Stir the cooked pasta, chicken, broccoli, Alfredo sauce, garlic powder, onion powder, salt, and pepper in a large bowl until well combined.

3: Top With Cheese And Abke

1. Pour the mixture into the prepared baking dish.
2. Top with the mozzarella and Parmesan cheese.
3. Bake the dish for 25-30 minutes until the cheese is melted and bubbly, and the casserole is heated through.
4. Let chicken and broccoli alfredo casserole rest for 5 minutes before serving.
5. Serve warm with finely chopped parsley or cilantro on top. Garlic bread and a green salad will be great on the side too!

Storage

Store leftover chicken bake in the fridge in an airtight container for 3 days. Reheat in a microwave.

You can also freeze chicken broccoli alfredo pasta bake for 2-3 months.

Substitutions & Variations

• You can use leftover turkey for this bake too. If you don’t have precooked chicken, quickly sear some bite-sized pieces of chicken breasts.
• Use this recipe to make homemade alfredo sauce.
• Use different cheeses that melt well like Gouda, Swiss, Monterey Jack, or Gruyere cheese.
• Seasoning variations: use dried herbs or Italian seasoning, and add minced garlic or roasted garlic instead of the powder. Fresh garlic has so much flavor! You can also use Poultry seasoning mix.
• Add some heat with red pepper flakes.
• The cream cheese or half and half added to the pasta will make ultra-creamy Alfredo sauce.
• Make crunchy topping. Combine Panko Breadcrumbs with melted butter and spread the mixture on top of the dish before baking. It will turn golden and add a nice texture.
