  • 1 large head of cauliflower cut into bite sized pieces
  • 2 tablespoons olive oil
  • 1 teaspoon salt divided
  • 1/2 teaspoon pepper divided
  • 2/3 cup sour cream
  • 1/3 cup heavy whipping cream
  • 2 teaspoons minced garlic
  • 1 1/2 cups shredded cheddar cheese
  • 5 slices bacon cooked and crumbled
  • 1/4 cup green onions chopped


  • Preheat the oven to 450. Spread the cauliflower pieces in an even layer on a rimmed baking sheet. Drizzle with the olive oil and sprinkle with 1/2 teaspoon salt and 1/4 teaspoon pepper. Roast 15-20 minutes, until crisp-tender, then remove from the oven and leave the oven on.
  • While the cauliflower is roasting, mix together the sour cream, heavy cream, minced garlic, and remaining 1/2 teaspoon salt and 1/4 teaspoon pepper.
  • Toss the cauliflower pieces with the sauce until coated. Mix in half of the cheddar cheese, half of the bacon, and half of the green onions.
  • Pour the cauliflower mixture into a casserole dish, and top with the remaining cheese and bacon. Bake 10-15 minutes, until the cheese is melty. Sprinkle with the remaining green onions. Serve hot.
