- 4 (about 3 lbs total) lamb shanks
- 1 1/2 tsp salt
- 1 tsp black pepper
- 3 tbsp olive oil
- 1 large yellow onion, chopped
- 3 medium carrots, chopped
- 2 celery stalks, chopped
- 4 garlic cloves, minced
- 16 fl oz seasonal Irish craft beer
- 2 cups beef broth
- 2 tbsp tomato paste
- 2 fresh rosemary sprigs
- 2 fresh thyme sprigs
- 2 medium parsnips, peeled and chopped

Instructions
- Step 1: Preheat oven to 325°F. Season 4 lamb shanks with 1 1/2 tsp salt and 1 tsp black pepper.
- Step 2: Heat 3 tbsp olive oil in a large oven-safe pot over medium-high heat. Sear lamb shanks on all sides until deeply browned, about 4 minutes per side. Remove and set aside.
- Step 3: Add 1 large chopped yellow onion, 3 chopped carrots, 2 chopped celery stalks, and 4 minced garlic cloves to the pot. Sauté for 5-6 minutes until vegetables soften and become fragrant.

- Step 5: Return lamb shanks to the pot along with 2 sprigs fresh rosemary and 2 sprigs fresh thyme. Bring to a simmer, cover, and transfer to the oven.
- Step 6: Braise lamb shanks in oven for 2.5 to 3 hours until meat is fork-tender and falling off the bone.
- Step 7: Meanwhile, boil 2 medium peeled and chopped parsnips and 2 medium peeled and chopped potatoes in salted water for 20 minutes until tender. Drain and mash with 3 tbsp unsalted butter and 1/2 cup whole milk until smooth.
- Step 8: Serve lamb shanks over a bed of root vegetable mash, spooning some of the braising liquid and vegetables over the top.
