Pat the beef stew meat dry with a paper towel and season evenly with the sea salt and black pepper.
Heat the extra virgin olive oil in a heavy-bottomed pot over medium-high heat.
Add the beef to the pot and sear until browned on all sides, then remove the beef and set it aside on a plate.
In the same pot, add the chopped yellow onion and minced garlic, sautéing for 2-3 minutes until the onion is translucent and fragrant.
Add the sliced carrots and diced parsnips to the pot, stirring to combine with the aromatics.
Return the browned beef to the pot and pour in the beef broth and dried thyme.
Bring the liquid to a gentle boil, then reduce the heat to low and cover the pot with a tight-fitting lid.
Simmer the stew for 45 to 60 minutes, or until the beef is fork-tender and the root vegetables are soft.
Serve warm in a deep bowl, ensuring a generous portion of beef and vegetables in every serving.
