Instructions
Preheat the oven to 375°F (190°C).
Remove the leaves and core from the cauliflower heads. Cut them into florets.
Fill a large pot with water, bring to a boil, and add the cauliflower florets. Boil for 8-10 minutes or until tender.
Drain the cauliflower well and transfer it to a large mixing bowl.
Mash the cauliflower with a potato masher or use a blender for a smoother texture.
Add the butter, heavy cream, sour cream, 1 1/2 cups of cheddar cheese, half of the parmesan cheese, garlic powder, onion powder, salt, and black pepper to the mashed cauliflower. Mix well until creamy and smooth.
Fold in the chopped scallions and crumbled bacon.
Transfer the mixture into a greased 9x13-inch baking dish. Spread it evenly.
Top with the remaining cheddar cheese and parmesan cheese.
Bake in the preheated oven for 30-35 minutes or until the top is golden brown and bubbly.
Remove the casserole from the oven and let it rest for 5 minutes before serving.
Garnish with additional scallions if desired and serve warm.
