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 evenly browned and cooked through. 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 well to combine, and let the mixture simmer for 10 minutes until thickened to a rich, cohesive filling.
05 - Once the sweet potatoes are done, remove them from the oven. Split each one open lengthwise and fluff the interior flesh with a fork.
06 - Spoon the Sloppy Joe mixture generously over each opened sweet potato. Garnish with chopped fresh parsley or shredded cheddar cheese if desired. Serve hot.
