1. Combine ground beef, egg, bread crumbs, milk, onion, garlic, carrots, thyme, salt, pepper, Worcestershire, mustard and 1 Tbsp ketchup in a large bowl. Knead gently with hands until well combined. Form into 12 small patties.
2. Heat oil in a large skillet placed over medium-high heat. Add patties and cook until cooked through, about 6 to 8 minutes per side. Remove from pan to plate, tent with foil.
3. Return skillet to medium heat. Add brown sugar, remaining 3 tablespoons ketchup and 1 tablespoon water. Cook until bubbling and sugar is dissolved, scraping pan of flavorful residue. Spoon glaze over cooked patties and serve on slider buns.
