I’ve recently found myself on a quest to lighten up my family’s favorite recipes and in doing so, I’ve become reaquainted with cauliflower.  To me, cauliflower had become one of the forgotten vegetables.  I love the taste of cauliflower, however, I often find myself gravitating more towards broccoli, green beans or even squash.

I recently made a spicy mashed cauliflower side dish a few weeks ago and it was fantastic.  In fact, my kids thought it was made with potatoes.  That recipe got me thinking of substituting cauliflower for potatoes in one of our favorite casseroles.  To my surprise, it tasted heavenly.  But why shouldn’t it?  This cauliflower casserole had so many amazing flavors in it.  I didn’t feel I was using cauliflower as a potato substitute but as an additional pleasant element of flavor.  Adding the cauliflower to this cheesy and flavorful casserole makes ordinary cauliflower outrageous.

How to Make Twice Baked Cauliflower Casserole

I cooked the cauliflower until it was tender.  Using a potato masher, I mashed it a little, making sure to leave a few nice chunks.  Then I mixed in a little sour cream, a splash of heavy cream, minced green onions, an egg, shredded cheddar cheese and crisp pieces of bacon.  I sprinkled a hefty handful of additional cheese over the top and baked the casserole in the oven for about 30 minutes.

For my vegetarian son, I put a little of the cauliflower casserole without the bacon into a couple of ramekins.

  1. This sounds absolutely divine! I’m a big fan of cauliflower and it always goes so well with gooey cheese. What a warm, comforting dish. I like the idea of adding scrambled egg, too, for some more protein.
