In a large dutch oven, warm 3 tbsp oil over medium-high heat. Add the 2 lb beef and sear until the outsides have browned. Remove to a plate and set aside.
Add 1 tbsp oil into the pot and add the 2 cloves garlic and the diced onion. Cook until translucent and aromatic.
Add the 2 carrots, ½ leek, and parsnip and cook, stirring occasionally, for about 5 minutes until softened.
Add the sprigs of thyme, 2 bay leaves, and ½ tsp black pepper. Cook again for about 5 minutes.
Add the 3 potatoes and the seared meat into the pot along with the warm stock.
Cover the dutch oven with a lid, and bring the stew to a boil. Reduce the stew to a simmer and allow it to simmer for about an hour, stirring occasionally.
After an hour, check if the meat is tender. If it is not, cook for another 20 minutes. When the meat is tender, serve and enjoy!
