Ingredients

Rack of Lamb:

  • 1 rack of lamb (69 bones), Frenched or not (Note 1)
  • 1 ¼ tsp salt
  • ¾ tsp black pepper
  • 2 tbsp olive oil

Dijon Mustard “Glue”:

  • 3 tsp egg, lightly whisked (Note 2)
  • 3 tbsp Dijon mustard
  • 1 tbsp fresh rosemary leaves, finely chopped
  • 1 small garlic clove, minced

Garlic Parmesan Crumb:

  • 1 cup Panko breadcrumbs (Note 3)
  • 2 tbsp Parmesan, finely grated
  • 1 garlic clove, finely minced
  • ¼ tsp salt and pepper each
  • 2 tbsp fresh rosemary leaves, finely chopped
  • 30 g / 2 tbsp butter, melted

Creamy White Wine & Mustard Sauce (Optional, Note 5):

  • 1 cup dry white wine
  • 1 cup low-sodium chicken stock
  • 1 cup heavy cream
  • 1 tbsp Dijon mustard
  • 1/8 tsp salt and pepper each

Instructions

  1. Preheat Oven
    Preheat oven to 200°C (390°F).
  2. Prepare the Rack of Lamb
    Pat lamb dry and season evenly with salt and pepper. Heat olive oil in a skillet over medium-high heat. Sear lamb on all sides for 2–3 minutes until golden.
  3. Prepare Dijon Mustard “Glue”
    In a small bowl, mix whisked egg, Dijon mustard, chopped rosemary, and minced garlic. Brush evenly over seared lamb.
  4. Make Garlic Parmesan Crumb
    Combine Panko breadcrumbs, Parmesan, minced garlic, rosemary, salt, pepper, and melted butter. Mix until crumbly and fragrant.
  5. Apply Crumb Topping
    Press crumb mixture evenly over mustard-coated lamb, ensuring complete coverage.
  6. Bake the Lamb
    Place lamb on a roasting tray and bake in preheated oven for 15–20 minutes for medium-rare (adjust cooking time for preferred doneness).
  7. Optional Sauce
    In a saucepan, combine white wine and chicken stock. Reduce by half over medium heat. Stir in cream, Dijon mustard, salt, and pepper. Simmer until thickened. Serve alongside sliced lamb.
  8. Serve
    Rest lamb for 5–10 minutes before slicing. Serve with sauce and your choice of sides.

Notes

Note 1: Frenched racks offer a cleaner presentation but are optional.

Note 2: Egg helps the crumb adhere to the lamb.

Note 3: Panko breadcrumbs create a light, crisp texture.

Note 5: Sauce is optional but adds richness and pairs beautifully with the herb crust.
