Ingredients

  • 2 large heads of cauliflower cut into florets
  • 8 ounces cream cheese softened
  • 1 cup sour cream
  • 2 cups shredded Colby Jack cheese divided
  • 8 slices bacon cooked and crumbled
  • 4 green onions thinly sliced, divided
  • 2 cloves garlic minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon paprika

Instructions

  • Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  • Steam the cauliflower until tender, about 5-7 minutes. Drain well and pat dry with paper towels. (For microwave steaming: Place florets in a microwave-safe bowl with 2 tablespoons of water, cover tightly with plastic wrap, and microwave for 5-7 minutes.)
  • Prepare the cheese mixture: In a large bowl, mix the cream cheese, sour cream, 1 cup of Colby Jack cheese, half of the crumbled bacon, half of the green onions, minced garlic, salt, and pepper.
  • Combine with cauliflower: Add the steamed cauliflower to the bowl and gently fold to coat it with the cheese mixture.
  • Assemble the casserole: Transfer the mixture to the prepared baking dish. Top with the remaining 1 cup of cheese, the remaining bacon, and sprinkle with paprika.
  • Bake for 20-25 minutes, or until the cheese is melted, bubbly, and the edges are lightly browned.
  • Cool and serve: Let the casserole cool for 5 minutes, then sprinkle with the remaining green onions before serving. Enjoy!
