01 - Preheat the oven to 325°F.
02 - Pat the short ribs dry with paper towels and season generously with salt and black pepper.
03 - Heat olive oil in a large Dutch oven over medium-high heat. Sear the short ribs on all sides until well browned, about 3-4 minutes per side. Remove and set aside.
04 - In the same pot, add onion, carrots, and celery. Sauté for 5 minutes until softened. Stir in garlic and cook for 1 more minute.
05 - Add tomato paste, stirring for 1-2 minutes. Deglaze the pot with bourbon, scraping any browned bits from the bottom. Cook for 2 minutes until slightly reduced.
06 - Stir in maple syrup, soy sauce, Dijon mustard, apple cider vinegar, smoked paprika, and beef stock. Bring to a simmer.
07 - Return the short ribs to the pot, nestling them into the sauce and vegetables.
08 - Cover and transfer to the preheated oven. Braise for 2.5-3 hours or until the meat is fork-tender.
09 - Remove the lid for the last 30 minutes to allow the glaze to thicken and caramelize.
10 - Remove the ribs from the pot and set aside, covered. Skim excess fat from the sauce and simmer on the stovetop to thicken further if desired. Serve ribs drizzled generously with the maple-bourbon glaze.
