Cauliflower Casserole

Steamed cauliflower is loaded with cheese sauce, bacon, sour cream, and chives in this cauliflower casserole side dish.

Why this recipe works

Cauliflower has never tasted better. I mean, who doesn’t love dousing vegetables in a creamy cheese sauce? Much like our broccoli casserole, this loaded cauliflower casserole is the perfect accompaniment to all sorts of main dishes whether it be for the holidays or alongside your weeknight meal.

This cauliflower bake is similar to a loaded baked potato. It has chives, sour cream, bacon, and loads of cheesy goodness. If that’s not enough to convince you, I’m not sure what is!

Ingredient Info and Substitution Suggestions

CAULIFLOWER – You will need 1 head of cauliflower, cut into bite-sized pieces equalling approximately 6 cups. In this recipe, we cook the cauliflower in a steamer basket, however, you can also cook it in the microwave. Place it in a microwave-safe bowl and add ¼ cup water. Cover with a plate and cook for 5 minutes. Drain all the water and pat dry.

ADDITIONS – If you don’t care for sour cream, you can omit this or substitute it with Greek yogurt. If you like things spicy, add some diced chilis and use pepper jack cheese. We used cheddar cheese and monterey jack, but you could also use colby jack in place of cheddar. I always recommend shredding your cheese from the block as opposed to buying prepackaged shredded cheese as it contains preservatives that do not melt as well and can make your cheese sauce grainy.
