Ingredients You’ll Need
This Roast Lamb with Spring Herb Crumbs Recipe relies on a handful of simple yet powerful ingredients, each chosen to build layers of flavor and add amazing texture. From fresh herbs bursting with aromatic oils to the light crunch of panko crumbs, every component works together seamlessly.
- Boneless leg of lamb (4 to 5 pounds trimmed): The star of the show, offering tender, juicy meat that’s perfect for roasting.
- Olive oil (3 tablespoons divided): Adds richness and helps the crust adhere while keeping the lamb moist.
- Kosher salt (2 teaspoons): Essential for seasoning and enhancing the natural flavors of the meat.
- Black pepper (1 teaspoon): Provides gentle heat and a peppery balance.
- Garlic (4 cloves minced): Delivers a pungent, savory depth to the herb paste.
- Fresh rosemary (2 tablespoons finely chopped): Brings an earthy, woody aroma that pairs perfectly with lamb.
- Fresh thyme (2 tablespoons finely chopped): Adds subtle herbal notes with a slightly minty edge.
- Fresh parsley (1/4 cup finely chopped): Infuses freshness and bright color into the crust.
- Lemon zest (1 tablespoon): Adds a zesty, citrus pop to lift the richness.
- Dijon mustard (2 tablespoons): Acts as a flavorful binder and gives a slight tangy bite to the herb paste.
- Panko breadcrumbs (1 cup): Provides a crispy, golden crust that contrasts beautifully with the juicy lamb inside.
How to Make Roast Lamb with Spring Herb Crumbs Recipe
Step 1: Prepare Your Oven and Lamb
Start by preheating your oven to 400°F, the perfect temperature to achieve a crispy crust and tender, pink meat. Pat the lamb dry using paper towels to remove any moisture—this step ensures the herb crumbs stick well and crisp up beautifully. Position the lamb on a roasting rack inside a large pan to allow air circulation for even cooking.
Step 2: Season the Lamb
Drizzle 1 tablespoon of olive oil evenly over the lamb, then generously sprinkle with kosher salt and black pepper on all sides. This basic seasoning will enhance the meat’s natural flavor and help develop a tasty crust beneath the herb topping.
Step 3: Make the Herb and Mustard Paste
In a small bowl, combine the minced garlic, fresh rosemary, thyme, parsley, lemon zest, and Dijon mustard. Mix until it forms a thick, vibrant green paste. This paste is what gives this recipe its distinctive springtime flair, delivering a fragrant punch that wraps the lamb in a cozy herbal hug.
Step 4: Prepare the Panko Crumbs
In another bowl, toss the panko breadcrumbs with the remaining 2 tablespoons of olive oil. This light coating of oil helps the crumbs brown evenly and become perfectly crisp without drying out.
Step 5: Assemble and Roast
Spread the herb and mustard paste over the entire surface of the lamb, pressing it down gently to cover every inch. Then, pat the oiled panko crumbs on top so they stick firmly to the herb layer. Place the lamb in the oven and roast for 1 hour to 1 hour 20 minutes, or until the internal temperature reaches 135°F if you prefer medium-rare. Cooking time may vary slightly depending on your oven and lamb size.
Step 6: Rest and Slice
Once roasted, remove the lamb from the oven and tent loosely with foil. Let it rest for 15 minutes to allow the juices to redistribute throughout the meat, ensuring every slice is juicy and full of flavor. Then slice and serve warm, savoring the delightful contrast between the crunchy crust and tender lamb.

Garnishes
To complement the rich flavors of this Roast Lamb with Spring Herb Crumbs Recipe, consider garnishing with a few sprigs of fresh rosemary or thyme for a beautifully rustic presentation. A light drizzle of good quality olive oil or a squeeze of fresh lemon juice before serving adds brightness and a lovely finish.
Side Dishes
Roast lamb pairs wonderfully with a range of sides. Roasted seasonal vegetables such as asparagus, new potatoes, or carrots enhance its Mediterranean vibe. Creamy mashed potatoes or a fluffy couscous salad with herbs also bring texture balance and soak up any delicious lamb juices.
Creative Ways to Present
For a more festive touch, slice the lamb and arrange it over a bed of mixed greens decorated with edible flowers and thin lemon slices. Alternatively, use leftovers to create mouthwatering sandwiches or luxurious grain bowls packed with fresh spring veggies and a dollop of tzatziki.
Make Ahead and Storage
Storing Leftovers
Leftover roast lamb can be stored in an airtight container in the refrigerator for up to 3 days. The herb crust remains flavorful, and the lamb stays tender, making it easy to enjoy again without losing any of its appeal.
Freezing
If you want to keep it longer, slice the lamb and wrap it tightly before freezing. Properly stored, the lamb retains good quality for up to 2 months. Defrost slowly in the refrigerator overnight before reheating.
Reheating
Reheat gently in a low oven or microwave to avoid drying out the meat. Covering with foil in the oven can help maintain moisture and preserve the crispy herb crust texture as much as possible.
FAQs
Can I use bone-in leg of lamb for this Roast Lamb with Spring Herb Crumbs Recipe?
Absolutely! Bone-in cuts can add extra flavor, though cooking times may slightly increase. Be sure to monitor the internal temperature for your preferred doneness.
What if I don’t have panko breadcrumbs?
