Old Fashioned Cauliflower Casserole – A Cauliflower Casserole with Sour Cream Recipe

Cauliflower Casserole has sour cream, fresh cauliflower, butter and butter crackers such as Ritz. Put these ingredients together for a delightful old fashioned cauliflower casserole to serve along side almost any meal.

Are you a cauliflower fan? I absolutely love cauliflower, so much so that I’d say it is my favorite vegetable.

It’s yummy raw with all that crunchy texture, but my downright favorite way to eat is is roasted or air-fried. Be sure to check out recipes for both those ways to eat it.

Old fashioned recipes with vegetables are a go-to for me too as well, so I was really excited about this cauliflower casserole with sour cream recipe that I found in my What’s Cooking, Teach Cook Book.

Cauliflower Casserole with Sour Cream

I’ll be honest, before adding this creamy cauliflower casserole to my repertoire, I had never boiled cauliflower, most certainly, never boiled it whole. It was really easy though.

Remove those leaves at the bottom, and then cut out the hard stems.  Then place in a deep saucepan, cover with water, and boil while covered with a lid until knife tender but not mushy.

Once you do that, it’s really easy to cut the cauliflower in florets. If you’re looking for a shortcut, start with a bag of frozen cauliflower florets that have been thawed.

Easy Cauliflower Bake

Once the cauliflower is prepped, all you need is a creamy sauce for this super easy cauliflower bake. The sauce is even easier with just two ingredients – butter and sour cream. No wonder it’s so rich and creamy. Melt the butter and the sour cream, in a small saucepan while you’re prepping the cauliflower.

And then, my favorite part of easy cauliflower bake is the crunchy, buttery cracker topping, made with Ritz crackers or generic butter crackers crushed up with melted butter.

So you’ve got the cauliflower, a creamy sauce, plus buttery, crunchy cracker topping. Put the together, and this old fashioned cauliflower casserole is the bomb.

Recipe FAQs

• Substitute margarine for butter, if desired.  The butter is divided into two steps, one stick for the sauce, and one stick for the cracker crumbs.
• Light sour cream can be used for regular, full-fat sour cream, if desired.
• To make this super easy, start with a bag of frozen, cauliflower florets that have been thawed.
• Bread crumbs, crushed cornflakes or any other casserole topping could be substituted for crushed crackers.
• I prefer to use Ritz or generic Ritz for the cracker crumbs, but you can use whatever crackers you have on hand, if you would like.

Recipe Variations

• Cheesy cabbage casserole is another great option. Add your favorite shredded cheese such as sharp cheddar cheese or Monterey jack cheese.
