½ cup Gochujang Seasoning
2 Tablespoons dark brown sugar
2 Tablespoons soy sauce
2 tablespoons unseasoned rice vinegar
2 teaspoons toasted sesame oil
3 pounds baby back pork ribs, separated into individual ribs
Toasted White Sesame Seeds for garnish
Whisk Gochujang, brown sugar, soy sauce, vinegar, and oil in a small bowl until smooth; season with salt.
Toss ribs and half of marinade in a 13x9” baking dish; set aside remaining marinade. Cover ribs with foil and chill at least 4 hours.
Preheat oven to 350°. Bake ribs, covered, until meat is tender, about 1 hour. Uncover and increase oven temperature to 450°. Roast, turning occasionally and brushing with reserved marinade during last 5 minutes, until ribs are deeply browned, glazed, and fork-tender, 40–45 minutes longer. Ribs can be marinated 1 day ahead. Keep chilled. Garnish with toasted sesame seeds just before serving.
