Best Cut for Roasting: Bone-In or Boneless?

The leg of lamb is the classic roast—it’s large, lean, and packed with flavor. But which one should you choose?

Bone-In Leg of Lamb

• More flavor from the bone
• Great for presentation
• Juicier and more traditional

Boneless Leg of Lamb

• Easier to carve
• Can be butterflied and rolled
• Still super flavorful with a herb rub

Both are excellent. Bone-in for a showy centerpiece, boneless for convenience and stuffing options.

What You’ll Need

Just a handful of fresh, flavorful ingredients to make this roast sing.

For the Lamb

• 4–6 lb leg of lamb (bone-in or boneless)
• Salt and black pepper
• Olive oil (for rubbing and roasting)

For the Herb Crust

• 4–5 garlic cloves
• 2 tablespoons chopped fresh rosemary
• 2 tablespoons chopped fresh thyme
• 1 tablespoon chopped parsley
• Zest of 1 lemon
• 2 tablespoons olive oil
• 1 teaspoon Dijon mustard (optional, for extra zing)

Want to switch it up? Use oregano or sage instead. Fresh herbs make a huge difference here.

How to Make Herb-Crusted Roasted Leg of Lamb

Let’s get into the roasting process—it’s simple and mostly hands-off.

Step 1: Prep the Lamb

• Bring the lamb to room temperature for about 45 minutes
• Pat dry with paper towels
• Season all over with salt and black pepper

Room temp lamb roasts more evenly and gives you that perfect medium-rare.

Step 2: Make the Herb Crust

• Mix garlic, herbs, lemon zest, oil, and mustard into a paste
• Rub it all over the lamb, pressing gently so it sticks

Don’t be shy—get into all the crevices and cover every inch.

Step 3: Roast

• Preheat oven to 425°F (220°C)
• Place lamb in a roasting pan on a rack (or bed of chopped onions and carrots)
• Roast at high heat for 20 minutes to sear
• Reduce oven to 350°F (175°C) and roast until internal temp hits:
  • 125°F for rare
  • 130–135°F for medium-rare
  • 140–145°F for medium

Step 4: Rest and Carve

• Remove from oven and tent with foil
• Let rest for 15–20 minutes
• Slice across the grain and serve

Resting helps the juices redistribute—don’t skip it!

Tips for a Perfect Roast Every Time

This is a no-fail method if you keep these things in mind:

• Use a meat thermometer for accuracy—seriously, it’s a game-changer
• Don’t skip the sear at high temp—it creates that perfect crust
• Use fresh herbs for best flavor (dry herbs just don’t hit the same)
• Let the lamb rest before slicing so it stays juicy
• Slice thinly against the grain for tender bites

Serve it sliced on a wooden board with herbs and lemon wedges—it’s rustic and stunning.

Make it your signature roast. You’ve got options.

How to Store and Reheat Leftovers

Lamb leftovers are incredible—here’s how to keep them just as delicious.

Storing

• Refrigerate slices in an airtight container for up to 4 days
• Store with juices to keep the meat moist

Freezing

• Freeze sliced lamb in freezer bags for up to 2 months
• Thaw overnight in the fridge and reheat gently

Reheating

• Warm in a 300°F oven, covered, with a splash of broth or juices
• Avoid the microwave—it can make the lamb rubbery

FAQs

1. Can I make this with a smaller cut of lamb?

Yes! If you’re using a smaller boneless roast (2–3 lbs), reduce the cooking time and keep a close eye on the temperature. You can still use the same herb rub and method—just scale down the seasoning a bit and adjust roasting time accordingly.

2. What if I don’t have fresh herbs?

You can substitute dried herbs, but use less—about one-third the amount. Fresh herbs bring brightness and aroma that dried versions can’t quite match. If you must use dried, boost the flavor with extra garlic, lemon zest, or a little mustard for zing.

3. How do I prevent the lamb from drying out?

Use a meat thermometer and don’t overcook it! Medium-rare is ideal. Let it rest after roasting, and be sure the oven isn’t too hot after the sear. Roasting at 350°F helps cook it slowly and evenly, keeping it moist inside with a crispy outside.

4. Can I roast lamb ahead of time?

You can! Roast the lamb, let it cool, and slice. Reheat slices in the oven, covered, at 300°F with a splash of broth. Or serve it cold over salad or in sandwiches. Just don’t skip the resting step if you’re serving it right away.

5. Can I use this herb rub for other meats?

Absolutely. It’s fantastic on pork tenderloin, chicken, or even beef roasts. You can also use it on grilled vegetables or mix it into compound butter for steak. The garlic-herb-lemon combo is classic and works with almost anything.

6. What’s the best wine to pair with this lamb?

Red wines like Cabernet Sauvignon, Syrah, or Pinot Noir pair beautifully with herb-crusted lamb. If you prefer white, go for a bold option like Chardonnay. The herb crust and richness of the meat pair well with something robust, earthy, and balanced.

7. Can I cook lamb in a roasting bag or covered pan?

You could, but the crust won’t be as crispy. Roasting uncovered is best for that golden, herb-infused outer layer. If you’re worried about drying it out, loosely tent with foil for part of the cook, then remove for the last 20–30 minutes.

8. What kind of thermometer should I use?

A digital instant-read thermometer is your best friend for this recipe. Insert it into the thickest part of the roast (not touching the bone) for an accurate read. It takes the guesswork out of roasting and guarantees perfect doneness every time.

9. Can I stuff the lamb with herbs or garlic?

Yes! If you’re using a boneless leg, you can butterfly it and stuff it with the herb mix before rolling and tying it. This adds tons of flavor from the inside out. It’s especially great with goat cheese, spinach, or olives.

10. Is this good for Easter or holiday meals?

It’s perfect. Herb-crusted lamb is a classic for Easter and spring feasts. It’s impressive, festive, and pairs beautifully with seasonal produce like asparagus, peas, and fresh herbs. Plus, it feeds a crowd and makes the whole kitchen smell amazing.
