Ingredients

  • 1 medium cauliflower (2 1/2 to 2 3/4 pounds)
  • salt
  • 12 cup creme fraiche (see note)
  • 34 cup grated gruyere cheese
  • kosher salt
  • fresh ground black pepper
  • 3 tablespoons dry plain breadcrumbs
  • 3 tablespoons hazelnuts, toasted and coarsely chopped (see note)
  • 2 tablespoons chopped chives (to garnish) or 2 tablespoons flat leaf parsley (to garnish)

Method

  • Butter 2-quart oven-to-table baking dish or gratin pan.
  • Set aside.
  • Cut off and discard base of cauliflower, then cut head into small, individual florets.
  • Bring large pot of water to boil and salt generously.
  • Add cauliflower florets to pot and cook until tender (but not mushy) when pierced with a sharp knife, about 5 minutes.
  • Drain florets and pat dry with a clean kitchen towel.
  • Place cauliflower in prepared dish and toss with creme fraiche and half of the cheese.
  • Season to taste with salt and pepper.
  • Sprinkle remaining cheese over cauliflower, then top with bread crumbs and hazelnuts.
  • Bake on center rack of preheated 375 degrees F oven until cheese has melted and bread crumbs and nuts are golden, 20 to 25 minutes or more.
  • Garnish with chives or parsley.
  • Notes:
  • Creme fraiche is available in most supermarkets.
  • If you can't find it, this recipe works well; it needs to be made at least 6 hours in advance.
  • Whisk 1 cup whipping cream and 1/3 cup sour cream together in medium non-reactive bowl.
  • Let stand at room temperature until thickened, 6 hours or longer.
  • Cover and refrigerate.
  • Store up to 1 wk, covered, in refrigerator.
  • Makes 1 1/3 cups.
  • To toast hazelnuts:
  • Spread on a rimmed baking sheet and bake in a preheated 350 degrees F oven until browned and fragrant, 6 to 8 minutes.
  • When cool enough to handle, place nuts in a kitchen towel and rub together to remove as much of the skins as possible.
