Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper for easy removal.
- In a large skillet, cook the ground beef over medium heat until browned and cooked through. Drain excess fat.
- Add diced onion and bell pepper (if using) to the skillet and cook for 3-4 minutes until softened. Stir in the garlic powder, onion powder, smoked paprika, salt, and pepper.
- Add tomato sauce, ketchup, mustard, brown sugar, and Worcestershire sauce to the skillet. Stir well and simmer for 5-7 minutes to thicken the sauce. Remove from heat and let cool for a few minutes.
- Roll out the pie crusts on a flat surface and cut out 6-8 circles (about 4-5 inches in diameter). Place a spoonful of the cooled Sloppy Joe filling in the center of each circle.
- Fold the dough over to form a half-moon shape, sealing the edges with a fork. Brush the top of each hand pie with the beaten egg.
- Preheat your air fryer to 375°F (190°C). Place the hand pies in the air fryer basket in a single layer, leaving some space between them. Air fry for 8-10 minutes, or until golden brown and crispy.
- Let the hand pies cool for a few minutes before serving. Enjoy with dipping sauces like ranch or extra ketchup.
