Let’s dive into making this delicious stew. Here’s how you can recreate this comforting dish in your own kitchen:

1. Preheat your oven to 300°F (150°C).
2. In a large Dutch oven, heat olive oil over medium-high heat. Add the beef cubes in batches, browning them on all sides. Remove the beef and set aside.
3. In the same pot, add the diced onion and garlic. Sauté until the onion becomes translucent, about 5 minutes.
4. Return the beef to the pot, then stir in the tomato paste. Cook for an additional 2 minutes to enhance the flavors.
5. Pour in the beef broth and red wine (if using), scraping up any browned bits from the bottom of the pot.
6. Add the carrots, parsnips, potatoes, and turnip. Stir in the thyme, bay leaf, salt, and pepper.
7. Bring the mixture to a simmer, then cover the Dutch oven with a lid and transfer it to the preheated oven.
8. Cook for 2 to 3 hours, or until the beef is tender and the vegetables are cooked through.
9. Remove the bay leaf before serving. Taste and adjust seasoning if necessary.
