Ingredients

  • 1 large head of cauliflower, cut into bite-size florets
  • 2 BBQ sausage links, cooked and chopped (or 1½ cups cooked diced chicken)
  • 1/2 cup mayonnaise
  • 1/2 cup sour cream
  • 2 cups shredded cheese (1 cup cheddar, 1/2 cup mozzarella, 1/2 cup Parmesan)
  • 1/4 cup chopped chives or green onions
  • Salt and black pepper to taste

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Cut cauliflower into small florets. Microwave in a covered dish with a splash of water for 8–9 minutes until fork-tender. Drain and set aside.
  3. Cook and chop the sausage (or other protein) into bite-size pieces.
  4. In a large bowl, mix mayonnaise, sour cream, 1 cup of cheese, and half the chopped chives or green onions until smooth.
  5. Add cauliflower and cooked meat to a 9×13-inch baking dish. Pour the creamy mixture over and stir gently to coat evenly.
  6. Top with remaining cheese (1 cup) and the rest of the chives or green onions.
  7. Bake uncovered for 20 minutes, or until the cheese is melted, bubbly, and golden.
  8. Let rest for 5 minutes before serving.

Notes

  • Drain cauliflower well and pat dry to avoid a watery casserole.
  • Use any preferred protein such as chicken, turkey, or plant-based sausage.
  • Try different cheeses like gouda, Colby, or pepper jack for a flavor twist.
  • For extra crunch, top with buttered breadcrumbs before baking.
  • Make ahead and refrigerate up to 24 hours before baking.
  • Store leftovers in the fridge for up to 4 days or freeze for up to 2 months.
