Preheat oven to 300°F (148°C), then generously season the short ribs with salt and pepper.
Warm oil in a Dutch oven until shimmering. Sear the short ribs until all sides are golden brown, about 1 ½ minute for each side. You may have to do this in batches until all the short ribs have had a chance to cook. Set the meat aside.
In the same pot, add the carrots, celery, and onion. Cook until the onions become translucent and soften for about 10 minutes.
Next, add the garlic, tomato paste, and flour; stir to combine.
Deglaze the pot with broth and cooking wine - careful to scrape up any brown bits left behind from searing the beef. Then, bring the mixture to a bowl. ,
Turn off the heat and nestle the reserved short ribs into the pan, along with thyme and butter. Cover with the lid and braise in the oven for 2 ½ to 3 hours.
Serve braised short ribs with mashed potatoes or mashed cauliflower to soak up all the yummy goodness.
