Why This Recipe Works

It’s simple, easy, and delicious. The beauty of a recipe like this is you can make everything from scratch or use up a bunch of extras or leftovers.

The best part of this casserole recipe is the simple, common, and often on-hand ingredients become a hearty and satisfying meal the entire family will love.

We used a grocery store rotisserie chicken because of how convenient they are. You’ll want to make this with cooked pasta. If you’ve ever made too much pasta for a meal, this chicken broccoli casserole is the tastiest way to use it up.

And quite possibly the best reason is there’s no condensed cream of chicken soup or cream of mushroom soup.

Chicken Broccoli Casserole Ingredients

Ingredients to make chicken broccoli casserole: mozzarella cheese, rotisserie chicken, butter, broccoli, bacon, milk, granulated garlic, pepper, flour, shell pasta, and onion.
  • Cheese — We used mozzarella cheese for is mild, smooth, and creamy flavor. Pre-shredded cheeses aren’t recommended for this recipe.
  • Protein — For easy cooking, we used chopped rotisserie chicken along with cooked and crumbled bacon.
  • Pantry staples — Flour, onion, black pepper, granulated garlic, and milk.
  • Pasta — Small pasta, like shell or elbow is recommend for this dish.
  • Broccoli — Frozen broccoli florets with stems made the dish even quicker to make.

How to Make Broccoli Chicken Casserole

Step 1 — Preheat the oven broiler and adjust the racks to be at least 5 inches from the element. Melt the butter in the Dutch oven over medium high heat. Begin to sauté the onion and whisk in the granulated garlic and black pepper.

Step 2 — Once the onions have soften whisk in the flour until it makes a paste.

Step 3 — Slowly pour in the milk and whisk to incorporate the roux.

Step 4 — Whisk in the cheese by the handful, making sure it doesn’t clump and becomes smooth. Reserve about a half a cup for the topping.

Step 5 — Stir in the crumbled bacon, reserving a tablespoon for the topping.

Step 6 — Add the broccoli and stir it in well. Allow the broccoli to heat through.

Step 7 — Stir in the cooked pasta.

Step 8 — Add the chicken. Make sure everything is well combined.

Step 9 — Sprinkle the reserved cheese and bacon over the top. Place in the oven and broil for 5-9 minutes, or until the top is bubbly golden brown.

Adaptation and variations

Cheese — Use your favorite. Cheddar cheese, pepper Jack, and such. Sprinkle Parmesan cheese on top for a slight tangy bite.

Pasta — You really can use any pasta size or shape, but the amount might vary.

Protein — Swap the chicken for ham, beef chunks, or even ground beef. If you’re not going to use rotisserie chicken, season raw chicken breast and saute in a bit of olive oil in the dutch oven before beginning the recipe.

Vegetables — Toss in peas, carrots, corn, greens, whatever you and your family love best. If you prefer fresh broccoli over frozen broccoli, we’d recommend blanching it for a few minutes before tossing it in the cheese sauce.

    Made this for my family and for my pregnant daughter’s family. I want to freeze for her to use as she needs.

    I had to add salt and pepper. The butter is unsalted, I didn’t add salt to the pasta. I tasted it and felt it needed flavor. I didn’t have bacon, so I was missing that. We are a salty family, so even with the 3 slices of bacon, I believe we’d still think it needed salt.

    Otherwise it’s a great recipe, very quick after the chopping of broccoli and chicken is done. It only needs a little browning on top by broiling, because all the ingredients are pre cooked. Good job Ned! Thanks.

    Just YES. This is my kind of recipe. The broccoli makes it feel wholesome, and I swap in whole wheat or chickpea shells for even more protein.

    This casserole is delicious! Creamy, cheesy, and very flavorful. I subbed Brussels instead of broccoli and with the bacon it was perfection! Great recipe, Ned!
