How to Make Buttermilk Brined Lamb with Mint and Pistachio Relish Recipe
Step 1: Prepare the Buttermilk Brine
Start by mixing the buttermilk, minced garlic, chopped rosemary and thyme, salt, black pepper, and optional cayenne pepper in a large bowl. This fragrant blend is the foundation of the dish’s tender, flavorful lamb. The buttermilk’s gentle acidity works wonders on the meat’s texture.
Step 2: Brine the Lamb
Submerge your bone-in lamb fully in the buttermilk mixture. Cover the bowl and refrigerate for at least four hours, but for best results, leave it overnight. This allows the lamb to soak up all those wonderful flavors while developing a juicy, melt-in-your-mouth quality.
Step 3: Preheat the Oven
While the lamb is brining, get your oven ready by preheating it to 375°F (190°C). This will ensure an even, perfect roast once the lamb is seared and ready.
Step 4: Make the Mint and Pistachio Relish
In a separate bowl, combine the chopped mint leaves, roughly chopped pistachios, honey, lemon juice, and olive oil. Stir gently and let the mixture sit while you prepare the lamb. This relish offers a fresh and crunchy contrast to the rich roast.
Step 5: Remove and Dry the Lamb
Once the brining time is up, take the lamb out of the buttermilk and gently pat it dry with paper towels. This step is important for getting a beautiful sear on the meat, locking in juices and flavor.
Step 6: Sear the Lamb
Heat a large oven-safe skillet on medium-high and add a little olive oil. Sear the lamb on all sides until it’s golden brown — this should take about 10 minutes. The sear creates a delicious crust that enhances the texture and flavor.
Step 7: Roast the Lamb
Transfer the skillet straight to your preheated oven. Roast the lamb for 30 to 40 minutes, depending on your preferred doneness (aim for 135°F internal temperature for medium-rare). The roasting gently cooks the lamb through while preserving its juiciness.
Step 8: Rest and Serve
After roasting, let the lamb rest on a cutting board for 10 to 15 minutes. This resting period is key to allowing the meat’s juices to redistribute, ensuring every slice is succulent. Once rested, carve the lamb and generously top it with the bright mint and pistachio relish for an unforgettable flavor combination.
How to Serve Buttermilk Brined Lamb with Mint and Pistachio Relish Recipe
Garnishes
Fresh garnishes elevate the dish even further. Sprinkle a few extra chopped mint leaves and chopped pistachios on top when serving to add bursts of color, crunch, and aroma that complement the relish perfectly.
Side Dishes
This lamb pairs beautifully with a range of sides. Think roasted root vegetables, creamy mashed potatoes, or a crisp cucumber salad to balance the richness. Even a simple herbed couscous or lemony quinoa can highlight the fresh notes of the relish brilliantly.
Creative Ways to Present
For a stunning presentation, slice the lamb thinly and fan it out on a serving platter, then spoon the mint and pistachio relish in ribbons down the center or dolloped alongside. Serve family-style to share the warmth and joy this recipe inspires.
Make Ahead and Storage
Storing Leftovers
Store any leftover lamb in an airtight container in the refrigerator for up to three days. To keep the relish vibrant, store it separately in a small container so you can add it fresh when ready to serve again.
Freezing
You can freeze cooked lamb slices, but the texture is best when fresh. Wrap the lamb tightly in plastic wrap and then in foil or place in a freezer bag. Freeze for up to three months. Thaw overnight in the fridge before reheating.
Reheating
Warm leftover lamb gently in the oven at 300°F (150°C) wrapped in foil to retain moisture. Alternatively, reheat slices quickly in a hot skillet with a splash of water or broth. Add fresh mint and pistachio relish just before serving for that perfect flavor boost.
FAQs
Can I use a different cut of lamb for this recipe?
Absolutely! While lamb leg or shoulder bone-in is ideal for this recipe because of their flavor and texture, you can use boneless cuts or lamb chops. Just adjust the brining and cooking times accordingly to avoid overcooking.
How long should I brine the lamb for best results?
For the most tender and flavorful outcome, brine the lamb overnight for at least 8 hours. However, if you’re short on time, a minimum of 4 hours will still offer good results.
Is the cayenne pepper necessary in the recipe?
Not at all! The cayenne pepper is optional and adds a gentle heat that balances the richness of the lamb. Feel free to leave it out if you prefer a milder flavor.
Can I prepare the mint and pistachio relish ahead of time?
Yes, the relish can be made a few hours ahead and kept refrigerated. This actually helps the flavors meld together nicely. Just give it a stir before serving.
What can I substitute for buttermilk if I don’t have any?
You can make a quick buttermilk substitute by mixing 2 tablespoons of lemon juice or white vinegar with enough milk to make 1 cup. Let it sit for 5 to 10 minutes before using in the brine.

- ½ teaspoon cayenne pepper (optional for heat)
Mint and Pistachio Relish
- ½ cup pistachios, roughly chopped
- 1 cup fresh mint leaves, finely chopped
- 1 tablespoon honey
- Juice of 1 lemon
- 2 tablespoons olive oil
Instructions
- Prepare the Buttermilk Brine: In a large bowl, combine buttermilk, minced garlic, rosemary, thyme, salt, black pepper, and cayenne pepper. Mix well to blend the flavors.
- Brine the Lamb: Submerge the lamb completely in the buttermilk mixture. Cover the bowl tightly and refrigerate for at least 4 hours, preferably overnight, to tenderize and infuse the meat with flavor.
- Preheat the Oven: While the lamb is brining, preheat your oven to 375°F (190°C) to get it ready for roasting after searing.
- Make the Mint and Pistachio Relish: In a separate bowl, combine chopped mint, pistachios, honey, lemon juice, and olive oil. Stir well and set aside to allow the flavors to meld while the lamb cooks.
- Remove Lamb from Brine and Dry: After brining, take the lamb out and pat it thoroughly dry with paper towels to ensure a good sear.
- Sear the Lamb: Heat a large oven-safe skillet over medium-high heat and add a little olive oil. Sear the lamb on all sides until it develops a golden-brown crust, approximately 10 minutes.
- Roast the Lamb: Transfer the skillet with the lamb to the preheated oven. Roast for 30 to 40 minutes, or until your desired doneness is reached (135°F for medium-rare) using a meat thermometer for accuracy.
- Rest the Lamb: Remove the lamb from the oven and let it rest for 10 to 15 minutes. Resting allows the juices to redistribute within the meat, ensuring tenderness and moisture.
- Slice and Serve: Carve the lamb into slices and serve it topped generously with the mint and pistachio relish for a fresh, nutty contrast to the rich meat.
Notes
- For more heat, increase the cayenne pepper amount or add chili flakes to the brine.
- Use a meat thermometer to ensure lamb is cooked perfectly to your preferred doneness.
- Overnight brining yields the best flavor and tenderness, but a minimum of 4 hours will still improve the meat.
- The relish can be prepared a few hours ahead and refrigerated to deepen flavors.
- Allowing the lamb to rest after roasting is crucial for juicy, tender meat.
- If you don’t have fresh herbs, dried rosemary and thyme can be substituted but use about half the amount.
