To make this Loaded Cauliflower Casserole, start by pre-heating your oven to 425 degrees and buttering a 9x13 baking dish and setting it aside. 

To cook your bacon, spray a baking sheet with non stick spray and lay your bacon out flat on the pan. Bake for 15-20 minutes or until crispy before removing the bacon to a paper towel lined plate while you prepare the remainder of your recipe. 

Next, add your cauliflower florets to a large strainer over a pot filled with 1-2 inches of water, bring to a boil and then cover, steaming broccoli for 2-3 minutes. When done, remove from heat and set aside. 

In a large bowl, combine mayonnaise, sour cream, spices, most of the bacon and green onions along with the cauliflower and half of the cheddar cheese. Mix well and then transfer your cauliflower mixture to the buttered casserole dish. Sprinkle on the remaining cheese, bacon and green onions and bake for 15-20 minutes. Remove from oven, let sit for 5 minutes before serving.
