01 - Preheat the oven to 400°F. Prick each sweet potato several times with a fork and arrange on a baking sheet. Bake for 40–45 minutes until fork-tender when pierced.
02 - While the sweet potatoes bake, heat a large skillet over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until thoroughly browned. Drain any excess fat if needed.
03 - Add the chopped onion, bell pepper, and minced garlic to the skillet. Sauté for 4–5 minutes until the vegetables are softened and fragrant.
04 - Stir in the tomato sauce, tomato paste, Worcestershire sauce, ketchup, and brown sugar. Season with smoked paprika, chili powder, cumin, salt, and black pepper. Pour in the broth, stir to combine, and simmer for 10 minutes until the mixture thickens to a rich consistency.
05 - Once baked, remove the sweet potatoes from the oven. Split each one lengthwise down the center and fluff the interior flesh with a fork.
06 - Spoon the Sloppy Joe mixture generously over each opened sweet potato. Garnish with chopped parsley or shredded cheddar cheese if desired. Serve immediately while hot.
