Ingredients you need

Ingredient notes and substitutions
- Cauliflower: You want a nice large head of fresh cauliflower, which is available pretty much year round in your supermarket’s produce section. And here’s a handy guide on how to cut it up into the florets you need.
- Milk: Either whole or lowfat milk will work just fine – don’t use skim.
- Cheddar Cheese: You can use any variety from milk to extra sharp! We love sharp for maximum cheesy flavor.

How to make this recipe
STEP 1: First you need a nice big head of cauliflower.

Cauliflower is a weird and wonderful vegetable, don’t you think? It looks like a bouquet of flowers from another planet. A super delicious bouquet of flowers.
STEP 2: You want to cut that cauliflower up into nice bite-sized florets and steam those florets until they are nice and tender.

STEP 3: Preheat your oven to 400 and find a nice big casserole dish – 9 x 13 is great if you have one.

STEP 4: While the cauliflower is steaming, stir up a quick and easy cheese sauce by melting 2 tablespoons of butter, stirring in 2 tablespoons of flour, then whisking in 1 cup of milk until things are slightly thickened. You are looking for a consistency of heavy cream, more or less.

STEP 5: Stir in a cup of cheddar cheese until it is nice and melted and smooth.

STEP 6: Spread the cauliflower out in your casserole dish, pour the cheese sauce over it, grind on a little fresh pepper and bake for 30 minutes.

Cool it off for a little bit (I know! So hard!) and then you are ready to serve up what is about to be your new favorite vegetable recipe.
Recipe FAQs
If you have a steamer basket, pop the cauliflower in the basket, settle the basket in a pot with a couple of inches of water, cover it with the pot lid, bring the water to a boil and steam until the cauliflower is tender, about 8 to 10 minutes. No steamer basket? A strainer will work just fine as a substitute.
If you absolutely can’t find fresh, then yes. If it is precooked just let is defrost. If it needs cooking, defrost and then steam it.
You can! Just make sure it is a meltable kind – Monterey Jack, Swiss and Muenster are all good options. Just make sure it is chopped or shredded.
It can! When you are ready to serve it up, bring it to room temperature and then pop it in a 350 oven for about 10-15 minutes.

Notes
Cauliflower: You can use frozen cauliflower in a pinch, but this recipe is at its very best when you use fresh cauliflower. It’s available pretty much all the time in the produce section of your grocery store.
Cheddar Cheese: Cheddar comes in various flavor varieties from mild to extra sharp. I like sharp cheddar for this recipe, but you can use any kind you like. You can also shred it yourself or get the bag of pre-shredded cheddar in the dairy section of your supermarket.
