Method
Lamb and Marinade
Prepare Lamb
Remove the lamb racks from the refrigerator 30–45 minutes before cooking so they come to near room temperature. Pat dry thoroughly with paper towels. Trim any excess fat from the cap if necessary, leaving a thin layer for flavor.
Season and Marinate
In a small bowl combine olive oil, minced garlic, chopped rosemary, chopped thyme, Dijon mustard and red wine. Add 2 tsp kosher salt and 1 tsp black pepper and mix to a paste. Rub the mixture evenly over the meat side of both racks (not the exposed bones). Let rest at room temperature for 15–20 minutes or refrigerate covered for up to 2 hours for deeper flavor. If refrigerated, bring back to room temperature for 30 minutes before roasting.
Herb Crust
Make the Crust
Preheat oven to 425°F (220°C). In a small bowl combine panko breadcrumbs, grated Parmesan, chopped parsley, lemon zest, melted butter and ground fennel if using. Stir until moist and cohesive. Taste and adjust with a tiny pinch of salt if desired.
Apply Crust
After the lamb has rested with the marinade, brush the exposed meat lightly with a thin layer of Dijon mustard (this helps the crust adhere). Press the herb-panko mixture evenly over the mustard-coated surfaces to form a uniform crust layer.
Searing and Roasting
Sear Racks
Heat a large, oven-safe skillet (cast iron preferred) over medium-high heat. Add 1 tbsp olive oil and heat until shimmering. Sear the lamb racks, crust-side down first if space allows or meat-side, for 1–2 minutes until golden brown. Sear the bones side briefly to color (30–45 seconds). Do not overcook—searing is to develop flavor and color.
Roast
Flip the racks so the crusted side faces up. Transfer skillet to the preheated 425°F oven. Roast racks for about 12–18 minutes for medium-rare (internal temperature 125–130°F / 52–54°C). For medium cook 18–22 minutes (130–140°F). Use an instant-read thermometer inserted into the thickest part of the meat (not touching bone) to check doneness.
Rest
Remove racks from oven and transfer to a cutting board. Tent loosely with foil and rest for 10 minutes—carryover cooking will raise the internal temp a few degrees. Resting lets juices redistribute and will make carving neater.
Pan Sauce
Deglaze
While the lamb rests, place the skillet back over medium heat (be careful—handle will be hot). If the skillet is very dry, add a teaspoon of oil. Add the minced shallot and crushed garlic and sauté 30–45 seconds until fragrant but not browned. Pour in 3 tbsp red wine to deglaze, scraping up browned bits from the bottom with a wooden spoon.
Reduce and Finish
Add 3 tbsp beef or lamb stock and the thyme sprig. Simmer until reduced by about half (2–4 minutes), then remove the thyme. Remove skillet from heat and whisk in 1 tbsp cold butter, one small cube at a time, to emulsify the sauce and give it sheen. Season with 1/2 tsp salt and 1/4 tsp black pepper, tasting and adjusting as needed. Strain the sauce into a small jug if you prefer a smooth finish.
Carving & Finish
Carve
Using a sharp chef’s knife, remove the twine if used and cut between bones into individual chops or cut each rack into 2–3 bone sections for plating. Wipe any loose crumbs before plating.
