Life has been hectic, busy, and all the things and then you throw in holiday prep and it can feel like a lot.
This broccoli cheese casserole is the perfect side dish to pair with chicken and rice for a family dinner.
If you have guests that are not a fan of green bean casserole this is a great option for changing things up.
This is a quick overview of the simple ingredients that you'll need to make an epic Broccoli Casserole! Specific measurements and step-by-step instructions are included in the printable recipe card at the bottom of the post.
- Frozen Broccoli Florets
- Cream of Mushroom Soup
- Sour Cream
- Sharp Cheddar Cheese
- French-Fried Onions
- Salt and Black Pepper
Broccoli - We use frozen broccoli since it is easy to keep on hand. If you are using fresh broccoli florets make sure to steam it before using it in the recipe.
French Fried Onions - If you are not a fan of French Fried Onions you can switch them out for crumbled Ritz Crackers or Seasoned Bread Crumbs.
Shredded Cheese - We like sharp cheddar cheese for the flavor but you can use any shredded cheese.
Cream of Mushroom Soup - This can be replaced with cream of chicken if you want to add meat to the recipe. You can use homemade or store-bought soup.
If you are looking to change this from a vegetable side dish to a full dinner meal. Here are a few of our favorite variations.
Rice - Add in a cup of cooked rice before baking to add more to this casserole.
Cauliflower - This recipe can be made with a mix of cauliflower and broccoli or you can substitute cauliflower for broccoli.
Chicken - Add in a ½ cup to a cup of diced or shredded chicken.
Turkey - Use leftover diced turkey to make this a great meal!
Garlic Powder - Sprinkle in your favorite seasoning to add a bit of extra flavor.
Crackers - If you are switching out the French Fried onions for Ritz crackers or similar you will need melted butter to stir into the crushed crackers.
8x8 Baking Dish - Also known as a 2-quart baking dish or casserole dish. We like to use a deep baking dish to hold all of the broccoli and cream sauce.
Heat resistant potholders - A couple of years ago, we had a fire scare when we didn't realize we had turned a burner on, and a cloth potholder caught fire. Thankfully we walked by the kitchen and saw the smoke and were able to get it out ourselves. Since then, we have only used these heat-resistant potholders.
