Preheat the oven while you prepare the cauliflower. Multi-tasking, am I right? Cut the cauliflower head into bite-sized florets and then place them into your baking dish. Drizzle with olive oil.
Prepare the bacon crumble. While your cauliflower is baking, use a nonstick skillet to cook your bacon until it’s brown and crispy. Crumble and set aside.
Prepare the cheese mixture. Use a bowl to combine the cream cheese, sour cream, and shredded cheddar cheese. Don’t forget to season the cheese mixture with a bit of salt!
Add to cauliflower. Once the cauliflower is done, comes the fun part. Remove the baking dish and dollop the cheese mixture all over top of the cauliflower. Sprinkle with remaining shredded cheddar cheese.
Bake and serve. Return the dish to the oven and bake for an additional 5-7 minutes or until the cheese is melted and bubbly. Sprinkle with crumbled bacon and sliced green onions before serving.
