  • Preheat oven to 350°F (165°C). Following the package directions, microwave the cauliflower packages one at a time until hot throughout, usually 3 to 4 minutes. Working quickly, in a mixing bowl combine the hot cauliflower, 1/2 cup of the cheddar cheese, the Parmesan cheese, cream cheese, sour cream, and butter. Stir until melted and combined. Stir in the garlic powder, 1/2 teaspoon salt, and 1/4 teaspoon pepper.
  • Spread mixture into a 9 by 9-inch (10-cup / 2.5-quart) casserole dish, sprinkle the remaining 1/2 cup cheddar cheese over the top and bake, uncovered, until the cheese is hot and bubbly, about 20 minutes. Sprinkle the bacon and green onion on top, and serve.
