This cheesy loaded cauliflower casserole recipe needs just 10 minutes prep. All the flavors of a loaded baked potato, without the carbs. Easy & delicious!
Preheat the oven to 450 degrees F (232 degrees C).
Transfer the cauliflower to a small 1.5 quart (1.4 L) casserole dish in a single layer. (Line the pan unless it's glass or stoneware. If there's too much cauliflower to fit in a single layer, roast on a larger baking sheet instead.) Roast in the oven for 15-20 minutes, until crisp-tender.
Bake for 5-10 minutes, until the cheese melts. Top with remaining green onions.
