Ingredients

Instructions

  1. Step 1: Heat 3 tbsp olive oil in a large heavy-bottomed pot over medium-high heat. Season 2 lbs cubed British lamb shoulder with 1 tsp salt and 1/2 tsp black pepper. Brown the lamb in batches for 5 minutes each until all sides are golden; remove and set aside.
  2. Step 2: In the same pot, add 1 large diced yellow onion, 3 diced carrots, and 2 diced celery stalks. Sauté for 6-7 minutes until softened and fragrant.
  3. Step 3: Stir in 4 minced garlic cloves and 2 tbsp tomato paste, cooking for 2 minutes until the paste darkens slightly.
  4. Step 4: Pour in 1 cup dry red wine, scraping up any browned bits from the bottom, and simmer for 5 minutes until reduced by half.
  5. Step 5: Return the browned lamb to the pot and add 2 cups beef broth, 2 tsp chopped fresh thyme, 1 tsp chopped fresh rosemary, 1 tsp salt, and 1/2 tsp black pepper. Bring to a boil, then reduce heat to low, cover, and simmer for 1 1/2 hours until the lamb is tender.
  6. Step 6: While the stew simmers, bring a pot of salted water to a boil. Add 2 cups frozen peas and cook for 2-3 minutes until bright green and tender. Drain and return to the pot.
  7. Step 7: Add 2 tbsp unsalted butter, 1/4 cup chopped fresh mint leaves, and 1/4 cup milk to the peas. Mash with a potato masher until smooth and season with 1/4 tsp salt and black pepper to taste.
  8. Step 8: Serve the lamb stew hot with a generous scoop of mint pea mash on the side.
