When I first decided to make a rack of lamb at home, I was a little intimidated, but this recipe made it so easy. It turned out to be one of the most impressive and delicious meals I’ve ever cooked.

The tangy Dijon mustard and fresh herbs create a beautiful, crunchy crust that locks in all the juices, making the lamb unbelievably tender. The aroma while it roasts is absolutely divine, and it truly tastes like something you’d get at a high-end restaurant. This has become my go-to for special occasions.

Ingredients

Here are the ingredients you will need. Selecting fresh, high-quality components is the key to making this dish truly spectacular.

1 rack of lamb (about 1 ½ – 2 lbs): Look for a “Frenched” rack, which means the bones are cleaned. A smaller, well-marbled rack is often more tender.
Salt and pepper: For seasoning the meat before searing.
2 tsp vegetable oil: A neutral oil with a high smoke point is perfect for searing the lamb without burning.
¾ cup panko breadcrumbs: These Japanese-style breadcrumbs are lighter and create a much crispier crust than regular breadcrumbs.
1 tsp lemon zest: Adds a bright, fresh note that cuts through the richness of the lamb.
1 tbsp fresh mint, minced: The classic pairing for lamb, mint provides a cool, sweet flavor. Always use fresh ingredients for the best taste.
1 tbsp fresh parsley, minced: Brings a clean, peppery freshness to the herb crust.
1 tsp fresh rosemary, minced: Its pine-like, aromatic flavor is a perfect complement to roasted meats.
¼ tsp Kosher salt: To season the breadcrumb mixture.
3 tbsp extra virgin olive oil: Binds the breadcrumb mixture together and helps it turn golden and crispy in the oven.
1 heaping tbsp Dijon mustard: Acts as a flavorful “glue” for the herb crust and adds a wonderful tangy depth. A quality brand makes a difference.

Note: The listed ingredient quantities will yield approximately 2 servings.

Variations

This recipe is fantastic as is, but it’s also easy to customize with different flavors or additions.

Add Garlic or Cheese: For an extra layer of savory flavor, add one or two minced garlic cloves or a few tablespoons of finely grated Parmesan cheese to the breadcrumb mixture.
Different Herbs: Feel free to experiment with other fresh herbs. Thyme, oregano, or even a little fresh basil would work well in the crust.
Spicy Kick: If you enjoy a bit of heat, add a pinch of red pepper flakes to the breadcrumb mixture for a subtle spicy kick.

Equipment you need

You only need a few basic kitchen tools to create this restaurant-quality dish.

Large skillet: Used to get a perfect sear on the lamb, which locks in juices and builds flavor.
Baking sheet or roasting pan: A surface to hold the lamb while it roasts in the oven.
Probe thermometer: The most reliable tool to ensure your lamb is cooked perfectly to your desired temperature without any guesswork.
Small bowl: For mixing the herb and breadcrumb crust.

How to Make Mustard and Herb Crusted Rack of Lamb?

By preparing the lamb and the crust separately before bringing them together, you ensure every element is perfect. The result is a beautifully cooked rack of lamb with a crunchy, flavorful crust that will impress anyone at the table.

1. Prepare and Sear the Lamb

First, preheat your oven to 350°F. Take the lamb out of the refrigerator about 30 minutes before cooking to allow it to come to room temperature for more even cooking. Trim any excess fat from the top of the lamb, then season it generously on all sides with salt and pepper.

Heat the vegetable oil in a large skillet over medium-high heat. Carefully place the lamb in the hot pan and sear until it’s nicely browned on all sides.

2. Make the Herb Crust

While the lamb is searing, you can prepare the crust. In a small bowl, combine the panko breadcrumbs, lemon zest, minced mint, parsley, and rosemary. Add the kosher salt, black pepper, and olive oil, and mix everything together until it is well combined and the breadcrumbs are lightly coated.

3. Coat the Lamb

Once the lamb is browned, remove it from the skillet and place it on your baking sheet. Spread the Dijon mustard in an even layer over the top fatty side of the lamb.

Press the breadcrumb mixture firmly onto the mustard, patting it down gently so it forms a solid crust. Let the prepared rack sit for about 10 minutes to help the crust adhere.

4. Roast to Perfection

Place the baking sheet on the top rack of the preheated oven. Roast until the lamb reaches your desired internal temperature, using a probe thermometer inserted into the thickest part of the meat.

For a perfect medium-rare, aim for 130°F. Once cooked, remove the lamb from the oven and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, ensuring the meat is succulent.

Additional Tips for Making this Recipe Better

Through making this dish, I’ve discovered a few things that help guarantee a perfect result every time.

I can’t stress enough the importance of a meat thermometer. It takes all the guesswork out of roasting and is the only way to ensure your lamb isn’t overcooked. For me, 130°F is the magic number for a juicy, pink medium-rare.
Letting the lamb rest is not an optional step! Tenting it loosely with foil for 10-15 minutes before you slice into it makes a huge difference in how juicy the final chops are. If you cut it too soon, all that flavor will end up on the cutting board.
I prefer to slice the rack into double chops (two bones per piece). It’s easier to cut, and I find it keeps the meat juicier and more of that delicious crust stays intact.

How to Serve Mustard and Herb Crusted Rack of Lamb?

This dish makes a stunning centerpiece for any meal. To serve, carefully slice the rested rack between the bones into individual or double chops. Arrange them on a platter or individual plates, and feel free to sprinkle any breadcrumbs that fell off during slicing over the top.

The vibrant green from the herbs against the pink lamb looks beautiful. This lamb pairs wonderfully with creamy mashed potatoes, roasted asparagus, or a simple risotto. A side of crispy roasted potatoes and onions would also be an excellent choice.

Make Ahead and Storage

A little prep can make this impressive meal even easier to assemble on the day you plan to serve it.

Make Ahead: You can sear the rack of lamb, apply the mustard, and press on the herb crust up to 24 hours in advance. Simply cover and store it in the refrigerator. Just be sure to let it sit at room temperature for at least 30 minutes before roasting.

Storage: Store any leftover lamb in an airtight container in the refrigerator for up to 3 days.

Reheating: To reheat, you can warm the lamb chops gently in a low-temperature oven or an air fryer to help crisp the crust back up. Avoid the microwave, as it can make the meat tough and the crust soggy.
