Cook time

  • For the cauliflower:
  • 1 head cauliflower, sliced into ⅓-inch "steaks"
  • 1 medium onion, sliced
  • 2 Tbsp olive oil
  • 4 whole garlic cloves
  • 4 sprigs thyme, or more as desired
  • Sea salt and freshly ground black pepper
  • For the sauce:
  • 1 cup light sour cream
  • ¼ cup prepared horseradish
  • 2 Tbsp fresh lemon juice

Preheat oven to 425°. Toss cauliflower and onion with olive oil, garlic, and thyme. Season with sea salt and freshly ground black pepper.

Lie flat on a large, rimmed baking sheet and roast, tossing occasionally, until the cauliflower is tender, about 40 minutes.

For the sauce: Stir together the sour cream, horseradish, and lemon juice until well-combined. Drizzle over the finished cauliflower or use as a dip.
