Ingredients

Scale
  • 1 rack of lamb (about 1.5 to 2 pounds / 680 to 900 grams), frenched for presentation
  • 2 tablespoons fresh rosemary, finely chopped (or 2 teaspoons dried if fresh unavailable)
  • 2 tablespoons fresh thyme leaves, chopped
  • 3 garlic cloves, minced
  • 1 teaspoon Dijon mustard
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons olive oil
  • 1 large head cauliflower (about 2 pounds / 900 grams), cut into florets
  • 1 cup heavy cream (or full-fat coconut milk for dairy-free)
  • 1 cup shredded Gruyère cheese (or sharp cheddar for a stronger flavor)
  • 2 tablespoons unsalted butter
  • 2 tablespoons all-purpose flour (use gluten-free flour blend if needed)
  • 1/2 teaspoon nutmeg (freshly grated if possible)
  • Salt and pepper, to taste
  • 1/4 cup Parmesan cheese, grated (optional, for topping)

Instructions

  1. Preheat your oven to 400°F (200°C). Allow at least 10 minutes for the oven to fully heat.
  2. In a small bowl, mix together chopped rosemary, thyme, minced garlic, Dijon mustard, salt, pepper, and olive oil to form a thick paste.
  3. Trim the rack of lamb if not already frenched, removing fat and silver skin. Pat dry with paper towels.
  4. Rub the herb paste all over the lamb rack, pressing firmly. Let the lamb sit at room temperature for 15 minutes.
  5. Heat a cast iron skillet or oven-safe pan over medium-high heat. Sear the lamb fat-side down for 2-3 minutes until golden brown, then flip and sear the other side for 2 minutes.
  6. Transfer the pan to the preheated oven and roast for 15 to 20 minutes for medium-rare (internal temperature around 130°F / 54°C). Rest the lamb for 10 minutes after roasting.
  7. While the lamb roasts, bring a large pot of salted water to a boil. Add cauliflower florets and cook for 5 minutes until just tender. Drain well and set aside.
  8. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux, stirring constantly.
  9. Slowly add heavy cream while whisking to avoid lumps. Cook until sauce thickens, about 3-4 minutes. Stir in nutmeg, salt, and pepper.
  10. Remove sauce from heat and stir in 3/4 cup of shredded cheese. Mix cauliflower into the sauce and transfer to a buttered baking dish.
  11. Sprinkle remaining cheese and Parmesan on top. Bake in the oven at 375°F (190°C) for 20 minutes or until golden and bubbly.
  12. Slice the rested lamb rack into individual chops. Plate with a generous scoop of creamy cauliflower gratin and garnish with fresh thyme or rosemary if desired.

Notes

Let the lamb come to room temperature before cooking to ensure even cooking and better crust adhesion. Use a meat thermometer to achieve perfect medium-rare doneness. Rest the lamb for 10 minutes after roasting to retain juices. Whisk the gratin sauce constantly and add cream slowly to avoid lumps. The gratin can be prepared ahead and baked just before serving. For dairy-free, substitute heavy cream with full-fat coconut milk and use vegan cheese blends.
