How to Make Mustard and Herb Crusted Rack of Lamb: Step-by-Step
1. Prep and Sear the Lamb
Preheat your oven to 425°F (220°C). Season the lamb racks all over with salt and pepper. Heat 2 tablespoons olive oil in a skillet over medium-high heat and sear the lamb for 1–2 minutes on each side until browned. (Optional, but enhances flavor and color.)
2. Make the Herb Crust
In a bowl, mix together breadcrumbs, garlic, rosemary, thyme, parsley, and olive oil. Stir until the mixture resembles damp sand.
3. Coat with Mustard and Crust
Brush the top side of the lamb racks generously with Dijon mustard. Press the breadcrumb and herb mixture firmly over the mustard-coated surface to form a crust.
4. Roast the Lamb
Place the lamb, crust-side up, on a foil-lined roasting pan or rack. Roast for 20–25 minutes for medium-rare (internal temperature of 125–130°F), or longer if you prefer it more well done.
5. Rest and Slice
Remove from the oven and tent loosely with foil. Let rest for 10 minutes before slicing between the bones into chops.

Frequently Asked Questions (FAQs)
Q: Do I need to sear the lamb before roasting?
A: While optional, searing adds a beautiful golden color and enhances flavor. If you skip this step, just make sure the crust gets nicely browned in the oven.
Q: Can I use dried herbs instead of fresh?
A: Fresh herbs are strongly recommended for this recipe. If using dried, reduce the quantity by half and add more olive oil to prevent the crust from drying out.
Q: What internal temperature should the lamb be cooked to?
A: For medium-rare, aim for 125–130°F; for medium, 135°F. Always rest the meat for at least 10 minutes before slicing to allow the juices to redistribute.
Q: Can I use lamb chops instead of a whole rack?
A: You can, but adjust the cooking time as chops will cook much faster—generally 8–10 minutes in the oven after searing.
Q: What sides pair well with this dish?
A: Roasted vegetables, garlic mashed potatoes, couscous, or a crisp green salad are all great options to complement the rich flavors of the lamb.
