How to Make a Cheesy Steamed Whole Head of Cauliflower
To start making this cheesy frosted cauliflower, cut the leaves out of the bottom of the cauliflower before setting it in the steamer. Don’t cut too much of the stem out otherwise the cauliflower will fall apart after it is steamed.
Place the cauliflower in a steamer basket, salt the cauliflower, and then steam for 12-15 minutes or until the cauliflower is fork-tender when you pierce it with a fork. if you do not have a steamer basket, you can place the cauliflower in a large stockpot with water in it and cook this way as well.
Transfer the steamed head of cauliflower into a round 2-3-quart baking dish. Then spread the creamy mustard sauce over the cauliflower. Season with more salt and pepper. Then layer slices of colby jack cheese over the top of the cauliflower.
This was the perfect side dish for the pork chops we had for supper. The frosted cauliflower is great as a potato substitute if you are trying to eat low-carb or keto. Leftover cauliflower also reheats well.
