Pat the beef chuck dry with paper towels and season thoroughly with sea salt and black pepper.
In a large heavy-bottomed pot or Dutch oven, cook the chopped bacon over medium heat until crisp, then remove the bacon bits and set aside.
Add the olive oil to the pot and sear the beef cubes in a single layer until deeply browned on all sides, then remove and set aside.
Add the halved mushrooms, sliced carrots, and pearl onions to the pot, sautéing until the onions are slightly translucent and the mushrooms have released their moisture.
Stir in the minced garlic and tomato paste, cooking for 1 minute until the mixture is fragrant and the paste darkens slightly.
Pour in the red wine to deglaze the pot, using a wooden spoon to scrape up all the flavorful browned bits from the bottom.
Return the beef and bacon to the pot, then pour in the beef bone broth and add the dried thyme and bay leaf.
Bring the liquid to a gentle simmer, then cover and reduce heat to low, cooking for approximately 90 minutes until the beef is fork-tender.
Remove the bay leaf and garnish the finished stew with freshly chopped parsley before serving.
