Braised Lamb Shank Recipe

Prep and Season

Preheat oven to 325°F (165°C). Pat lamb shanks dry with paper towel. Combine 1 tsp kosher salt and 1 tsp black pepper with the flour on a plate and dredge each shank lightly, shaking off excess.

Brown Shanks

Heat a large heavy oven‑proof Dutch oven over medium-high heat. Add olive oil and 1 tablespoon butter. When shimmering, add shanks (work in batches to avoid crowding) and brown on all sides, about 6–8 minutes per shank. Transfer browned shanks to a plate.

Sweat Aromatics

Reduce heat to medium. Add remaining 1 tablespoon butter to the pot. Add diced onion, carrots, and celery and cook until softened and starting to brown, about 6–8 minutes. Add smashed garlic and tomato paste; cook, stirring, 1–2 minutes until tomato paste darkens slightly.

Deglaze and Build Braising Liquid

Pour in the red wine to deglaze, scraping up browned bits from the bottom. Cook until wine is reduced by half, about 3–5 minutes. Add beef or lamb stock, rosemary, thyme, bay leaves, and remaining 1 tsp kosher salt. Bring to a simmer.

Braise

Return shanks to the pot, nestling them partially submerged in liquid. Cover the pot and transfer to the preheated oven. Braise until meat is very tender and pulls easily from the bone, about 2 to 2 1/2 hours.

Finish Shanks

Carefully remove shanks from the braising liquid and keep warm. Skim fat from surface of braising liquid and strain solids into a bowl, pressing to extract juices. Reserve liquid for demi-glace reduction.

Reduce and Enrich

Pour the reserved braising liquid into a saucepan and bring to a brisk simmer over medium-high heat. Reduce until liquid measures about 1 to 1 1/4 cups (concentrated, about 10–15 minutes depending on volume). Stir in 1 cup prepared beef demi‑glace and simmer 5 minutes to meld flavors. Off heat, whisk in cold butter cubes a few at a time to create a glossy sauce. Adjust seasoning with salt and pepper to taste. Keep warm.

Cook Potatoes

Place peeled potatoes in a pot and cover with cold salted water. Bring to a simmer and cook until very tender, about 15–20 minutes depending on size. Drain well.

Mash and Finish

Return hot potatoes to the pot or a bowl. Warm the milk and melt the butter together. Mash potatoes with a potato masher or ricer, gradually adding milk-butter mixture until smooth and creamy. Season with 1 tsp salt and 1 tsp white pepper. Hold warm.

Mix Gremolata

In a bowl combine toasted chopped pistachios, chopped parsley, lemon zest, minced garlic, 2 tbsp olive oil, 1 tbsp lemon juice, 1 tsp salt and 1 tsp black pepper. Stir to combine. Taste and adjust acidity or salt. Set aside at room temperature.

Make Chimichurri

In a food processor pulse parsley, cilantro, oregano, and garlic briefly until finely chopped (do not purée to a paste). Transfer to a bowl and stir in red wine vinegar, red pepper flakes, 6 tbsp olive oil, 3/4 tsp salt and 1/2 tsp black pepper. Let rest at room temperature for at least 15 minutes to marry flavors. Adjust seasoning.

Roast Vegetables

Toss baby carrots and asparagus with 2 tbsp olive oil, 1/2 tsp salt and 1/2 tsp black pepper. Spread on a sheet pan in a single layer and roast in 400°F (200°C) oven for 10–12 minutes until tender-crisp and slightly caramelized. Keep warm.

Spoon a generous portion of mashed potato onto each plate. Place one braised lamb shank on top or beside the mash. Spoon 2–3 tablespoons of the warmed demi‑glace over the shank and around the plate. Arrange roasted chef's vegetables to the side.

Finish by spooning a small amount of chimichurri beside or lightly over the shank for bright herb flavor, then sprinkle 1–2 tablespoons of pistachio gremolata over the meat for texture and citrus notes. Garnish with microgreens if using. Serve immediately.
