  • 2-2 1/2 lbs cauliflower - cut into large florets (think 2 bites)
  • 4 large shallots or 1 medium onion - diced to make about a cup
  • 2-3 cloves garlic - minced
  • 1/2 tsp anchovy paste - optional
  • 12 oil cured black olives - regular kalamata will do in a pinch, chopped, plus a few for on top
  • 1/2 tsp crushed red chili - or less if you don't like spicy
  • 2 Tbsp minced fresh Italian parsley
  • 3 Tbsp olive oil
  • 3/4 cups grated pecorino romano
  • 6 oz shredded friulano or mozzarella in a pinch


  • Pre-heat your oven to 375F.
  • Spread the florets on a baking sheet. Drizzle olive oil and toss to coat the cauliflower.
  • Roast about 30-35 minutes. You want them soft, not mushy. They will cook a little more in the gratin.
  • While the cauliflower roasts, heat a frying pan over medium low heat.
  • Add 1 Tbsp olive oil and cook the shallots/onions until soft.
  • Add the garlic, chili flakes and anchovy paste if you are using it and cook one minute more.
  • Toss the roasted cauliflower, onion mixture, parsley, olives and 1/2 cup of pecorino romano in a large bowl.
  • Combine the shredded friulano and the remaining pecorino.
  • Transfer to a shallow oven proof baking dish, spread the cheese mix and olives overtop and cook for 25-30 minutes. You want the cheese nicely browned and the cauliflower tender.
