Variations Ideas

  • Change the Cream of Soup – You can use any type of cream soup. We suggest cream of chicken or cream of mushroom if you prefer.
  • Add Rice – Add cooked rice to the casserole for even more flavor.
  • Change the Cheese – We used sharp cheddar cheese, but you can use any kind. I have used mild cheddar and even pepper jack cheese for a little bit of spice to the casserole.
  • Add Chicken – If you prefer, you can add in some shredded chicken for a complete meal. If I have leftover chicken, I will mix it in with the other ingredients.
  • Sour Cream – You can mix in sour cream with the ingredients for a creamier texture.
  • Cracker Topping – This casserole is still delicious if you prefer to omit the cracker topping.
  • Fried Onion – For the amazing onion flavor, you can top the casserole with some fried onion or mix it in.

Can I Make This in Advance?

Yes, this is the perfect casserole to make in advance. When I am hosting a holiday dinner, I like to prepare as much meals as I can in advance. Prepare the casserole as indicated and then place in the refrigerator.

If you have the room in your refrigerator, I would go ahead and place the mixture and place in the slow cooker. It will last 3-4 days in the refrigerator.

I would wait to add the crushed cracker topping until you are ready to place cook in the slow cooker.

Frequently Asked Questions

Can I use Fresh Broccoli instead of Frozen?

Broccoli is one of my favorite vegetables. In this recipe, you can use frozen or fresh broccoli florets. They both cook perfectly in the slow cooker with the other ingredients.

How to Store Leftover Broccoli Cheese Casserole

Place leftover slow cooker cheese broccoli casserole in an air tight container for about 3 to 4 days in the refrigerator. When we prepare this dish for the holidays, we always have so much turkey and ham leftovers, that we eat on it for several days.

How to Reheat Casserole

When you are ready to serve broccoli casserole, thaw in the refrigerator overnight. Place thawed broccoli casserole in a baking dish and reheat in the oven. You can also reheat in the microwave. If you reheat in the microwave, heat in 30 minute intervals and watch for hot spots.

Can you Freeze Broccoli Casserole after Cooking?

We recommend freezing the casserole unbaked. Prepare the casserole as indicated in the recipe. We recommend doubling the recipe and store properly so it is ready to go for all your holiday baking. Make sure to store in a freezer safe container and it will last about 3 months. If doubling the recipe, freeze in individual serving containers.
