Easy Boneless Honey Marinated Butterflied Leg of Lamb

The aroma of rosemary and honey, kissed by the flame, always transports me back to summer evenings spent at my grandmother’s farmhouse. She had a knack for making simple meals feel like feasts, and her butterflied leg of lamb, infused with the sweetness of honey and the earthy notes of rosemary, was a centerpiece of many family gatherings. It was always cooked on the grill to perfection, it was amazing! I remember the anticipation building as the sun dipped below the horizon, and the promise of tender, flavorful lamb hung heavy in the air. It’s a dish that embodies warmth, comfort, and the joy of sharing good food with loved ones.

Recipe Overview

• Prep Time: 24 hours 20 minutes
• Cook Time: 25 minutes
• Total Time: 24 hours 45 minutes
• Servings: 6-8
• Dietary Type: Gluten-Free

Ingredients

• 1 (5 lb) boneless butterflied leg of lamb

MARINADE

• 1/3 cup honey
• 1/3 cup vegetable oil
• Juice of 1 lemon
• 2 tablespoons Dijon mustard (can use a couple tablespoons more if desired)
• 1 small onion, chopped
• 2 tablespoons minced fresh garlic (can use more)
• 1 tablespoon fresh rosemary
• 1 teaspoon seasoning salt (or use white salt)
• Black pepper

Equipment Needed

• Large heavy plastic ziploc bag
• Large bowl
• Large frypan
• Large greased baking sheet

Instructions

1. In a large heavy plastic ziploc bag, combine the honey, vegetable oil, lemon juice, Dijon mustard, onion, garlic, fresh rosemary, salt, and black pepper. I use about 1-1/2 teaspoons of black pepper, but adjust to your preference.
2. Add the lamb into the bag and turn to coat it evenly in the marinade.
3. Seal the bag tightly, place it in a large bowl, and refrigerate for 24 hours. Turn the bag occasionally to ensure the lamb is evenly coated in the marinade. This lengthy marinating time is crucial for the flavors to penetrate the meat and tenderize it.
4. When you are ready to cook, remove the lamb from the plastic bag and discard the marinade. Do not reuse the marinade as it has been in contact with raw meat.
5. Let the lamb sit at room temperature for 1 hour and 15 minutes before cooking or grilling. This allows the lamb to cook more evenly.
6. Preheat your oven to 425 degrees Fahrenheit.
7. Pat the lamb dry with paper towels. This will help achieve a good sear.
8. Heat some oil in a large frypan over medium-high heat.
9. Sear the lamb on both sides for 5 minutes per side. Searing locks in the juices and creates a delicious crust.
10. Transfer the seared lamb to a large greased baking sheet. Make sure the baking sheet is large enough to accommodate the butterflied leg of lamb.
11. Cook the lamb for about 20-25 minutes for medium-rare. Cooking time may vary depending on the thickness of the lamb and your oven. Use a meat thermometer to check for doneness. For medium-rare, aim for an internal temperature of 130-135 degrees Fahrenheit. For medium, aim for 135-145 degrees Fahrenheit.
12. Let the lamb rest for 15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product. Slice against the grain for maximum tenderness.
13. Serve and enjoy!

Expert Tips & Tricks

• For an even deeper flavor, consider adding a splash of red wine vinegar to the marinade.
• If you prefer a stronger rosemary flavor, gently bruise the rosemary leaves before adding them to the marinade. This releases their aromatic oils.
• Don’t overcrowd the pan when searing the lamb. Sear it in batches if necessary to ensure proper browning.
• Use an instant-read thermometer to accurately gauge the internal temperature of the lamb. Insert it into the thickest part of the meat, avoiding any bones.
• To prevent the lamb from drying out during cooking, you can add a cup of beef broth or water to the baking sheet.
• For a different twist, try adding a pinch of red pepper flakes to the marinade for a subtle kick.

Serving & Storage Suggestions

This honey-marinated butterflied leg of lamb is a versatile dish that pairs well with a variety of sides. Consider serving it with roasted vegetables such as asparagus, potatoes, or carrots. A simple green salad with a lemon vinaigrette also complements the richness of the lamb. Alternatively, you could serve it with couscous or quinoa.

Leftover lamb can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze the lamb in freezer-safe bags or containers for up to 2-3 months. To reheat, thaw the lamb in the refrigerator overnight and then reheat it in a preheated oven at 325 degrees Fahrenheit until warmed through. You can also reheat it in a skillet over medium heat. Add a little bit of broth or water to prevent it from drying out.

Variations & Substitutions

• For a gluten-free version, ensure that your Dijon mustard and seasoning salt are gluten-free. Most Dijon mustards are naturally gluten-free, but it’s always best to check the label.
• If you don’t have fresh rosemary, you can substitute it with 1 teaspoon of dried rosemary.
• Instead of vegetable oil, you can use olive oil for a richer flavor.
• If you are not a fan of Dijon mustard, you can use whole-grain mustard or even a touch of horseradish for a similar flavor profile.
• For a sweeter marinade, consider adding a tablespoon of maple syrup along with the honey.
• You can add other herbs like thyme or oregano for a different flavor profile.
• Consider grilling the butterflied leg of lamb instead of baking it. Grill over medium heat for about 30 minutes, flipping occasionally, until cooked to your desired doneness.
