Add beef chunks to a large bowl and sprinkle with flour, salt, and black pepper. Toss to coat the beef evenly.
02 -
Heat 2 tablespoons of vegetable oil in a large, oven-safe pot or Dutch oven over medium-high heat. Add beef in batches to avoid overcrowding and brown on all sides for about 5 minutes per batch. Transfer cooked beef to a plate and cover with foil. Repeat with the remaining beef, adding more oil as needed.
03 -
Reduce heat to medium and deglaze the pot with red wine, scraping up any browned bits from the bottom with a wooden spoon.
04 -
Add butter to the pot and let it melt. Stir in the diced onion and minced garlic, cooking for 1 minute until fragrant.
05 -
Stir in Worcestershire sauce, tomato paste, and 4 cups of beef broth. Add the browned beef chunks back to the pot along with the quartered onion, whole garlic cloves, bay leaves, and thyme.
06 -
Cover and cook on low heat, occasionally skimming the broth, for about 1 1/2 hours until the beef is tender.
07 -
Preheat the oven to 300°F. Discard the thyme and bay leaves, then add the carrots, celery, mushrooms, and potatoes to the pot. Stir to combine.
08 -
Cover the pot and place it in the preheated oven. Cook for about 1 hour, or until the vegetables are tender. Add more broth or water if the stew becomes too dry.
09 -
Once done, remove the stew from the oven and adjust seasoning with salt and pepper. If the stew is too thin, use a cornstarch slurry to thicken it by stirring the mixture into the stew and boiling for 2 minutes.

Serve the stew warm, garnished with freshly chopped parsley.
