Cut the French bread in half lengthwise and place both halves cut-side up on the prepared baking sheet. In a small bowl, mix the softened butter with garlic salt and Italian seasoning until well combined. Spread this garlic butter mixture evenly over both bread halves.

Heat a large skillet over medium-high heat. Add the ground beef and cook for 6-8 minutes until browned, breaking it up with a spatula as it cooks. Add the diced onions, green peppers, and minced garlic. Continue cooking for another 4-5 minutes until the vegetables soften. Drain off any excess grease.

To the skillet, add tomato sauce, ketchup, brown sugar, mustard, Worcestershire sauce, black pepper, salt, onion powder, and paprika. Stir everything together until well combined. Reduce heat to medium-low and simmer uncovered for 6-8 minutes, stirring occasionally, until the sauce thickens to your desired consistency.

Divide the hot sloppy joe mixture between the two bread halves, spreading it evenly. Sprinkle the mozzarella and cheddar cheeses over the top of each loaded bread half. Bake in the preheated oven for 12-14 minutes until the cheese is completely melted and starting to turn golden brown at the edges.

Remove from the oven and let cool for 1-2 minutes. Cut each half into 3 pieces (or more for smaller portions) and serve immediately while hot and cheese is still gooey.
