Cheesy Cauliflower Casserole Recipe
This comforting Cauliflower Casserole is creamy, cheesy, and has added bacon! It’s the side that will be sure to satisfy everyone at the table. This side dish features cauliflower, bacon, cheesy sauce mixture, and topped with a bacon bread crumb topping.
I am crazy about cauliflower in every way, shape, or form. Be it roasted, mashed, as a pizza crust, or even raw. When cauliflower is combined with cheesy sauce and bacon, then it’s mouthful of comfort. This cheesy cauliflower side dish would make a beautiful addition to the holiday table.
There are a couple of variations you can make to this dish. You can use half broccoli and half cauliflower to make a broccoli cauliflower casserole. Try adding a little ham or chicken and make it a complete meal.
You can also try substituting different flavorful cheeses, like Asiago, goat cheese, Gorgonzola, or cheddar. (Be careful about the combination though.)
How To Make Cheesy Cauliflower Casserole
Preheat the oven to 375°F and lightly grease an 8×8 casserole dish.
Cut cauliflower florets off of the stem. Discard the stem.
Blanch cauliflower first: In a large pot, bring water to boil and blanch the cauliflower florets for about 4-5 minutes. Transfer them into an ice bath and let them cool. Take them out and dry off the excess water.
In a pot over medium heat, cook bacon bit until completely cooked and set them aside. Sauté shallots in some of the leftover bacon grease until golden.
Sprinkle flour over the shallots, whisk until completely coated and start slowly pouring in the stock and the milk. Stir in Dijon mustard, and season. Keep whisking slowly until mixture thickens.
Stir in the cheeses one handful at a time, and keep whisking until all melted and smooth.
Add in the cauliflower florets, mix well with sauce, and transfer to the casserole dish.
In a small bowl, combine the bacon bits, bread crumbs, and melted butter. Mix very well and spread the mixture over the casserole evenly.
Bake for about 20 minutes, until bubbly.
Make Ahead Tips:
There are two ways you can make preparations ahead of time:
You can blanch the cauliflower ahead of time and store it in an air-tight food storage container, in the refrigerator for a day or two. When ready, follow the recipe to make the casserole.
Another way to make it ahead of time is to prepare most of the cauliflower casserole and store it instead of baking. So prepare the casserole up to the step of adding the topping, spread the casserole in the baking dish you plan to use. Don’t add the topping yet. Make sure the casserole mixture is cooled, cover it, and refrigerate until the next day.
Store cooked bacon bits in another air-tight container. When ready to bake, take the casserole out, reheat bacon bits, and prepare the topping. Spread the topping over the casserole and bake as directed in the recipe.
Gluten Free Tips:
You can definitely make this cauliflower casserole gluten free with a couple of simple substitutions. Use gluten free all-purpose flour to make the cheese sauce and use gluten free Panko crumbs in the topping. Double check the labels on the remaining ingredients, like bacon and cheeses, to make sure they are gluten free.
