Crockpot Broccoli Casserole

Today we are sharing our Mom’s recipe with you. Jill remembers her making it every Thanksgiving and Christmas. It just was not a holiday feast if the broccoli and cheese casserole was not on the table. 

Mom would even make it for Dad’s work holiday potlucks. This broccoli casserole recipe is one that is super easy to make, and everyone loves. 

Putting veggies, especially broccoli, into your slow cooker is GENIUS because they hold their shape so well. You can prepare this broccoli casserole in the morning, turn the crockpot on, and focus on the other things you need to do throughout the day. Doing this also gives you extra space in your oven and on your stove-top! 

Here’s the best part, in addition to how easy it is to make this dish, the cleanup is even easier! Putting the foil in the slow cooker insert first makes sure the casserole doesn’t burn on the edges. But more importantly, it makes washing the crockpot a cinch. 

The list of benefits for making this Cheesy Broccoli Casserole in the crockpot goes on and on. We know this will become one of your favorite recipes that you will come back to for holiday parties and weeknight meals throughout the years to come.

Can you freeze broccoli casserole after cooking?

Broccoli is one of the best vegetables to cook! Not only is it healthy, but it is also an extremely forgiving vegetable. 

You can cook it in the microwave, steam it, roast it, or put it in the slow cooker. It’s super versatile. It also freezes well. 

Superfood status right there. What can’t broccoli do?! 

How do you reheat frozen broccoli casserole?

Remove the frozen broccoli casserole from the freezer to defrost while preheating the oven to 350 degrees. After the dish has thawed, loosely cover it with foil and bake for about 20-30 minutes. 

It will take longer if the casserole is still frozen. 

Can I substitute fresh broccoli for frozen in a casserole?

Absolutely! We all know fresh broccoli is delicious. You can easily substitute fresh for the frozen broccoli within this recipe.

How to make Slow Cooker Broccoli Casserole recipe:

STEP ONE:  Make a foil collar for the crockpot and line inside of the crockpot insert. 

STEP TWO: In a large bowl, add broccoli, celery soup, 2 cups of cheese, and green onions. You will then want to toss until the broccoli is coated.

Cook’s Tools:

• slow cooker

The Flavor and Recipe Variations

Instead of cream of celery soup, you can use cream of mushroom or cream of chicken. 

Sometimes I like to make this recipe using half cauliflower and half broccoli. 

How long is it good for:

Serve: As with most recipes with dairy products in them, you shouldn’t leave this Broccoli Casserole out for longer than 2 hours. 

Store: Transfer leftovers to an airtight container and keep them in the refrigerator for up to 4 days. 

Freeze: You can freeze the cooked casserole in an airtight container for 3-4 months. 

How to get the kids involved with this recipe: 

Ages 2-3: Let them help crush the crackers and sprinkle them on top. They will love getting to crush the crackers on purpose (see the picture above)! 

Ages 4-5: Have your little one help toss the ingredients together in the bowl.

Ages 6-8: Teach them how to insert the foil into the crockpot. Also, teach them how to turn on and set the crockpot. Learning this technique will help with future recipes as well. 

Ages 9-11: Supervise them while they prepare the entire recipe. Remember to have them read it twice before beginning the recipe. 

Ages 12+: Let them prepare the entire recipe, unsupervised, while you do the happy dance in the corner!
