Chicken Broccoli Casserole Recipe

Healthy Chicken Broccoli Casserole Recipe with chicken, mushrooms, rotini pasta and sauteed yellow onions. So Delicious!

This Healthy Chicken Broccoli Casserole is the perfect comfort food meal.

It is a healthier version of your typical cheesy broccoli casserole because it does not contain condensed mushroom or chicken soups.

The rotini pasta mixed with a sauteed onion/mushroom sauce, and chicken pieces, then topped off with freshly shredded sharp cheddar cheese is such a warm and cozy meal.

This was perfect for my fam on this cold and rainy day today. It's also one of those dishes that works great as leftovers.

Ingredients you will need:

1. 8 oz (3 cups) dry rotini
2. 4 cups of broccoli florets
3. Butter
4. 1 Yellow Onion
5. 8 oz container of sliced cremini mushrooms
6. Minced garlic
7. Chicken Stock
8. Milk
9. 2 cups shredded sharp cheddar cheese

What to serve with chicken broccoli casserole?

Since this dish has protein, veggies and carbs, there really is not a need for a side dish. Having said that, my family loves berries, so I sliced up some fresh strawberries and put them in a bowl in the center of the table. The berries disappeared by the end of the meal. They were a nice light side dish that complemented the casserole well.

Tips for this Chicken Broccoli Casserole with no soup:

1. You can turn this into a Rotisserie Chicken Broccoli casserole for a quicker meal prep time. Simply shred the chicken from a fully cooked rotisserie chicken from your local supermarket's deli.
2. Be sure to only cook the rotini to al dente, since it will cook more in the oven, and you want to avoid overcooking.
3. Use fresh broccoli. It just tastes better, I promise. Frozen broccoli has too much water in it and could lead to a soggier casserole if you do not remove the excess water well enough.
4. I love freshly shredded cheese. It tastes so much better in a dish like this one. The sharp cheddar is so perfect for this casserole.
5. You can swap out the chicken for tuna and make this a Tuna Broccoli Casserole.
6. You can also omit meat from the dish and turn it into a vegetarian noodle casserole.

This is an easy chicken broccoli casserole recipe that can serve a crowd and will warm them up on cold fall/winter days. We really enjoyed it and think you will too!
