It was one of those rare, slow afternoons when the kitchen was quiet except for the faint hum of the oven and the soft clinking of a wooden spoon against a bowl. I’d been craving a meal that felt like spring itself—fresh, bright, and comforting all at once. The idea of a tender spring lamb roast with fresh mint chimichurri had been simmering in my mind for a while, sparked by the smell of fresh mint from the garden and the promise of a juicy roast waiting to unfold. Honestly, I wasn’t entirely sure if the chimichurri would live up to the hype—it’s such a classic sauce but with mint, it felt like a gamble. I remember slicing into that lamb and feeling the juices run clear, the aroma filling the room with something almost nostalgic.

That day, I learned just how a simple sauce can transform a humble roast into something unforgettable. The freshness of the mint chimichurri cut through the richness of the lamb, leaving behind a balance that made me pause and savor every bite. This recipe stuck with me—not just because it was delicious, but because it felt like a little moment of calm, a perfect blend of flavors to mark the turning of seasons. If you’re looking for a dish that’s just as good for a holiday feast as it is for a quiet weekend lunch, this one’s got your back.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the fresh mint adds that seasonal pop that makes it feel special.

• Lamb Roast (Bone-in or Boneless), about 4 to 5 pounds (1.8 to 2.3 kg) – I prefer a leg roast for tenderness and flavor.
• Garlic, 4 cloves, minced – adds depth and aroma.
• Fresh Rosemary, 2 tablespoons, chopped – pairs beautifully with lamb.
• Olive Oil, 3 tablespoons – I always go with a good quality extra virgin like California Olive Ranch.
• Lemon Juice, from 1 lemon – brightens the marinade and chimichurri.
• Salt and Pepper, to taste – essential seasoning.
• Fresh Mint Leaves, ½ cup, finely chopped – the star of the chimichurri, use tender leaves if possible.
• Red Wine Vinegar, 2 tablespoons – balances the fresh herbs in chimichurri.
• Red Pepper Flakes, ¼ teaspoon (optional) – adds a gentle heat kick.
• Flat Leaf Parsley, ¼ cup, chopped – complements mint for a layered herb flavor.

For substitutions, if you prefer, Greek yogurt can be added to the chimichurri for creaminess, or almond flour can be used for a gluten-free option if you plan to thicken side dishes. In summer, swapping fresh mint for basil can give a different but just as delightful twist.

Equipment Needed

• Roasting Pan – A sturdy pan with a rack is ideal to allow heat circulation and prevent the meat from sitting in its juices.
• Sharp Chef’s Knife – For trimming and slicing the lamb and chopping herbs.
• Mixing Bowl – To whisk together the chimichurri ingredients.
• Meat Thermometer – Not mandatory, but I swear by it for perfect doneness (aim for 135°F/57°C for medium-rare).
• Wooden Spoon or Whisk – For mixing the chimichurri.
• Cutting Board – A stable one with juice grooves helps keep things tidy.

If you don’t have a roasting rack, placing the lamb on a bed of sliced onions or root vegetables works just fine. For budget-friendly options, a simple baking sheet and wire rack from most kitchen stores will do the trick. Keeping your knife sharp makes all the difference when prepping herbs and meat.

Preparation Method

1. Prepare the Lamb: Pat the lamb roast dry with paper towels. This helps the seasoning stick and encourages a beautiful crust. Trim any excess fat if needed, but don’t remove it all—it adds flavor and juiciness. (10 minutes)
2. Make the Marinade: In a small bowl, combine the minced garlic, chopped rosemary, lemon juice, olive oil, salt (about 1½ teaspoons), and black pepper (about 1 teaspoon). Whisk until blended. This simple mixture will infuse the lamb with bright, herbal notes. (5 minutes)
3. Marinate the Lamb: Rub the marinade all over the lamb, making sure to cover all sides. Let it sit at room temperature for 30 minutes to 1 hour, or refrigerate overnight for deeper flavor. If refrigerating, bring to room temp before roasting. (30 to 60 minutes)
4. Preheat the Oven: Set your oven to 375°F (190°C). Position the rack in the middle. (5 minutes)
5. Roast the Lamb: Place the lamb on a roasting rack in your pan. Roast for about 60 to 75 minutes, or until a meat thermometer reads 135°F (57°C) for medium-rare. Keep in mind that the temperature will rise slightly while resting. (60 to 75 minutes)
6. Rest the Meat: Remove the lamb from the oven and tent it loosely with foil. Let it rest for 15 to 20 minutes before slicing. This step is key for juicy, tender slices. (15 to 20 minutes)
7. Make the Mint Chimichurri: While the lamb rests, mix the chopped mint, parsley, red wine vinegar, olive oil (about 3 tablespoons), lemon juice, red pepper flakes, salt, and pepper in a bowl. Taste and adjust seasoning. The sauce should be bright and fresh, with a little zing from the vinegar and lemon. (10 minutes)
8. Serve: Slice the lamb against the grain into thick slices and spoon the mint chimichurri generously over the top. The contrast of warm meat and cool, herbaceous sauce is unbeatable.

Pro tip: If the lamb looks like it’s browning too quickly, loosely cover it with foil halfway through roasting. Also, keep an eye on your meat thermometer—it’s your best friend for avoiding overcooked lamb.

Cooking Tips & Techniques

Cooking lamb roast can feel intimidating, but with a few tricks, it’s straightforward and rewarding.

• Don’t skip the resting step. It’s tempting to dig in right away, but letting the meat rest allows juices to redistribute. Otherwise, you lose all that beautiful moisture on the cutting board.
• Use a meat thermometer. Lamb can quickly go from perfectly pink to dry. I’ve learned the hard way that eyeballing rarely works well here.
• Room temperature meat roasts more evenly. If you pop your lamb straight from fridge to oven, the inside cooks slower, risking uneven doneness.
• Fresh herbs make a big difference. Dried rosemary or mint just don’t give the same punch. If you don’t have fresh, hold off or add less.
• Chimichurri is best made fresh. The flavors brighten after a few minutes but start to lose vibrancy if made too far in advance.
• Multitasking tip: Make your chimichurri while the lamb rests—it saves time and keeps everything fresh.

Variations & Adaptations

This recipe is flexible—here are some ways you can adjust it:

• Dietary: For a dairy-free chimichurri, just skip any butter or yogurt additions. The olive oil base is naturally dairy-free.
• Seasonal: In fall or winter, swap mint with fresh thyme or oregano for a deeper, earthier flavor.
• Flavor Twist: Add a little grated horseradish to the chimichurri for a spicy kick that pairs beautifully with lamb’s richness.
• Cooking Method: If you don’t have an oven, you can slow-cook the lamb in a covered roasting pan at 325°F (160°C) for 2 to 2½ hours until tender.
• Personal Favorite: I once added a splash of pomegranate molasses to the chimichurri, which gave it a sweet-tart note that was surprisingly addictive.

Serving & Storage Suggestions

This lamb roast shines best served warm with a generous spoonful of fresh mint chimichurri. Slice it thick to keep the meat juicy. For sides, roasted baby potatoes, grilled asparagus, or a simple arugula salad with lemon vinaigrette complement the dish perfectly.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The lamb reheats gently in a low oven (about 300°F/150°C) wrapped in foil to prevent drying out. The chimichurri is best served fresh but can be stored separately in the fridge for up to 2 days—just bring it back to room temp before serving to revive its flavors.

As the flavors meld overnight, the lamb and chimichurri develop deeper, more harmonious notes—sometimes I even prefer it the next day in a sandwich or atop a salad.

Nutritional Information & Benefits

This recipe offers a protein-rich meal with healthy fats from olive oil and fresh herbs that provide antioxidants and vitamins. Lamb is a great source of iron, zinc, and vitamin B12, essential for energy and immune health.

The mint chimichurri adds freshness and supports digestion. For those watching carbs, this recipe is naturally low-carb and gluten-free.

Be mindful that lamb can be higher in saturated fat depending on the cut, so trimming excess fat helps balance the meal. Overall, it’s a nourishing choice that feels indulgent yet wholesome.
