Mustard and Herb Crusted Rack of Lamb Recipe

Ingredients

This recipe uses simple, fresh ingredients that come together beautifully.

1 cup fresh breadcrumbs – I recommend using freshly grated bread for a light, crisp texture.
1 tablespoon chopped fresh flat-leaf parsley – Adds brightness and balance.
1 tablespoon chopped fresh mint – Gives a cool, herby contrast to the rich lamb.
1 tablespoon chopped fresh rosemary – Adds warmth and fragrance.
½ teaspoon salt – Enhances all the other flavors.
½ teaspoon black pepper – Adds a little kick and depth.
2 tablespoons olive oil – Helps bind the crust and adds richness.
2 racks of lamb (about 1½ lb each), frenched and trimmed – Look for well-trimmed racks for even cooking.
3 tablespoons Dijon mustard – Acts as a flavor booster and glue for the crust.

Note: This recipe serves several people—perfect for a small dinner party or family meal.

Spice: Add a dash of chili flakes or smoked paprika for extra heat and smokiness.

Equipment You’ll Need

Be sure to gather everything before you start:

Meat Thermometer – To check doneness (aim for 130°F for medium-rare).

Basting Brush or Spatula – To spread mustard evenly.
Cutting Board and Sharp Knife – For slicing into clean chops after cooking.

How to Make Mustard and Herb Crusted Rack of Lamb?

This recipe is easier than it looks, and the payoff is huge. Here’s how I made it, step by step.

Make the Herb Crust Mixture

Start by making the delicious crust. In a mixing bowl, combine the breadcrumbs with parsley, mint, rosemary, salt, and pepper. Drizzle in the olive oil and mix everything until it’s well combined and slightly damp. The mixture should hold together when you press it between your fingers.

Prep the Lamb and Oven

Take the lamb racks out of the fridge and let them come to room temperature—this helps them cook evenly. While that’s happening, preheat your oven (or grill) to 375°F. Season the lamb all over with salt and pepper. Don’t skip this step—it builds the foundation for flavor.

Sear the Lamb for Extra Flavor

If you’re using a grill, place the lamb fat-side down and sear for a few minutes on each side to lock in the juices. This step adds beautiful color and deep flavor to the meat. Be sure not to overcook—it’s just a quick browning.

Add the Mustard and Herb Crust

Remove the lamb from heat and spread Dijon mustard over the fat side. Then gently press the herb-breadcrumb mixture onto the mustard layer. Make sure it’s fully coated and the crust sticks well. Press down firmly so it adheres.

Finish Cooking and Let It Rest

Place the lamb into your preheated oven (or back on the grill using indirect heat). Roast until the internal temperature reaches 130°F for medium-rare, which takes about 10 more minutes. Let it rest for at least 10 minutes before slicing so the juices stay inside.

Additional Tips for Making this Recipe Better

After making this recipe myself, here are a few things I learned that really helped:

Bring to Room Temp – Letting the lamb sit out before cooking prevents a raw center.
Use Fresh Breadcrumbs – Trust me, it makes the crust crispier and more flavorful.
Press the Crust Firmly – Don’t be shy—use your hands and pack it on well.
Check Temperature – A thermometer keeps you from overcooking or drying out the lamb.
Clean Grates – If you’re grilling, make sure the surface is clean and oiled to prevent sticking.

How to Serve Mustard and Herb Crusted Rack of Lamb?

Presentation makes this dish shine. I like to slice between the bones to make individual lamb chops and fan them out on a clean white platter. A few fresh mint or rosemary sprigs on top give a pretty, green pop.

You can serve it with sides like roasted potatoes, creamy mashed cauliflower, or grilled asparagus. And don’t forget the wine—a bold red like Cabernet or Pinot Noir pairs perfectly.

Make Ahead and Storage

Make Ahead

You can mix the breadcrumbs and herbs a day early—just keep the mixture sealed in the fridge. You can also season the lamb in advance to deepen the flavor.

Refrigeration

Leftovers? Store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven to keep the crust crisp.

Freezing

Freeze cooked lamb by wrapping tightly in foil and placing it in a freezer bag. It’ll keep well for up to 2 months. Thaw in the fridge overnight and reheat in the oven.
