Ingredients

For the Lamb:

• 2 racks of lamb (8 ribs each), frenched (about 1.5 to 2 lbs total)
• 6 cloves garlic, minced
• 2 tablespoons fresh rosemary, finely chopped
• 1 tablespoon fresh thyme leaves
• 1 teaspoon sea salt
• 1/2 teaspoon black pepper
• 2 tablespoons Dijon mustard (optional for extra flavor)
• 3 tablespoons olive oil

For the Butter Sauce:

• 4 tablespoons unsalted butter
• 2 garlic cloves, smashed
• 1 sprig rosemary
• 1 sprig thyme
• 1/4 cup dry white wine or chicken stock (optional)
• Salt and pepper to taste

Directions

Step 1: Prepare the Herb-Garlic Mixture

In a small bowl, combine minced garlic, rosemary, thyme, salt, pepper, olive oil, and optional Dijon mustard to form a thick paste.

Step 2: Prep the Lamb

• Pat lamb racks dry with paper towels.
• Score the fat cap lightly (do not cut into the meat).
• Rub the garlic-herb mixture all over the lamb, pressing it into the meat.
• Let it marinate at room temperature for 30 minutes or refrigerate up to overnight.

Step 3: Roast the Lamb

1. Preheat the oven to 450°F (230°C).
2. Place the lamb racks bone-side down in a roasting pan or oven-proof skillet.
3. Roast for 20-25 minutes for medium-rare (internal temp: 125–130°F / 52–54°C), or adjust time for desired doneness.
4. Tent with foil and rest for 10 minutes before slicing.

Step 4: Make the Butter Sauce

1. While lamb is resting, melt butter in a small saucepan over medium-low heat.
2. Add smashed garlic cloves, rosemary, and thyme.
3. Let it simmer gently for about 5 minutes. Optionally, deglaze with wine or stock and reduce for another 3 minutes.
4. Strain and season with salt and pepper.

Step 5: Slice and Serve

• Slice between the bones to portion the lamb into individual chops.
• Plate and drizzle generously with the warm butter sauce.

Tips & Variations:

Tips:

• Resting is essential: Resting allows the juices to redistribute, keeping the lamb moist.
• Use a thermometer: For precise doneness.
• Sear before roasting (optional): For extra crust, quickly sear the lamb in a hot skillet before roasting.

Variations:

• Crusted Lamb: Add breadcrumbs mixed with Parmesan to the herb paste for a crunchy crust.
• Spice it up: Add crushed red pepper flakes or smoked paprika for a kick.
• Different herbs: Try sage, marjoram, or oregano for a different aromatic profile.

Serving Suggestions

This elegant dish pairs beautifully with:

• Creamy mashed potatoes or garlic herb roasted potatoes
• Grilled asparagus or haricots verts (French green beans)
• A glass of full-bodied red wine like Cabernet Sauvignon, Syrah, or Bordeaux
• A side of mint yogurt sauce or chimichurri for a zesty contrast

Frequently Asked Questions (FAQ):

Q: Can I use boneless lamb instead of a rack?

Yes, but the presentation and flavor from the bones roasting will be different. A boneless lamb loin or leg can work; adjust cooking time accordingly.

Q: How do I “french” a rack of lamb?

“Frenching” means removing the fat and meat between the ribs. Many butchers offer this service, or you can do it with a sharp knife—YouTube has helpful tutorials.

Q: Can I make the butter sauce ahead of time?

Yes, but it’s best fresh. If you do make it ahead, store in the fridge and gently reheat over low heat.

Q: What if I don’t have fresh herbs?

Use dried herbs, but reduce the quantity by half (as dried herbs are more concentrated).

Q: How do I know when my lamb is done?

Use a meat thermometer. Here’s a quick guide:

• Rare: 120°F (49°C)
• Medium-Rare: 125-130°F (52-54°C)
• Medium: 135°F (57°C)
• Well Done: 145°F (63°C) – not recommended for lamb rack
