01 - Preheat the oven to 325°F.
02 - Pat the short ribs dry with paper towels and season generously with salt and black pepper on all sides.
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 ribs and set aside on a plate.
04 - Add onion, carrots, and celery to the same pot. Sauté for 5 minutes until softened. Stir in garlic and cook for 1 more minute until fragrant.
05 - Add tomato paste, stirring constantly for 1-2 minutes to develop flavor. Deglaze the pot with bourbon, scraping up 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, stirring to combine all ingredients.
07 - Return the short ribs to the pot, nestling them into the sauce and vegetables. Ensure the ribs are partially submerged in the liquid.
08 - Cover the pot with a tight-fitting lid and transfer to the preheated oven. Braise for 2.5 to 3 hours until the meat is fork-tender and pulling away from the bone.
09 - Remove the lid for the last 30 minutes of cooking to allow the glaze to thicken and caramelize on top of the ribs.
10 - Remove the ribs from the pot and set aside, covered to keep warm. Skim excess fat from the surface of the sauce. Simmer the sauce on the stovetop over medium heat for 5-10 minutes if further thickening is desired.
11 - Arrange ribs on serving plates and drizzle generously with the maple-bourbon glaze. Garnish with fresh herbs such as parsley or thyme if desired.
