Preheat the oven to 350 F
Season the lamb shanks generously with salt and pepper on all sides
In a large Dutch Oven heat up the tallow, ghee or oil
Sear the shanks over medium high heat until browned all over
Remove the shanks from the pot.
Add onions and cook for 3-4 minutes
Add garlic and cook for another 2 minutes
Add carrots, celery and parsnip and cook for about 10 minutes
Add wine and deglaze the pan and cook for another couple of minutes until some of the wine evaporates
Add cinnamon powder, a teaspoon of salt and half a teaspoon of pepper
Add tomato paste and crushed tomatoes
Place the lamb shanks back in the pot
Add beef broth and herbs, cover the pot and transfer to the oven for 2/½ hours.
Carefully remove the pot from the oven using protective mittens. Remove the shanks and check if your sauce is reduced enough. If not, put it on the stove and cook uncovered for another 10-15 minutes to thicken the sauce.
Serve with your choice of potatoes, pasta or rice. Garnish with parsley. Enjoy!
