Step 1: Make the Garlic Bread

Preheat your oven to 350°F (175°C). Take the loaf of Italian bread and slice it in half lengthwise, creating two long halves. In a small bowl, mix together the softened butter and garlic salt until well combined. Spread this garlic butter mixture evenly over both halves of the bread. Set the bread aside for now, as you’ll be topping it with the Sloppy Joe filling after it’s prepared.

Step 2: Cook the Sloppy Joe Filling

In a large skillet over medium-high heat, brown the ground beef, breaking it up with a spatula as it cooks. Cook for about 6-8 minutes until the beef is fully browned and no longer pink. Drain off any excess fat.

Once the beef is cooked and drained, add the chopped yellow onion to the skillet. Cook for an additional 3-4 minutes, until the onions soften and become translucent. Stir in the garlic powder, yellow mustard, ketchup, kosher salt, black pepper, and water. Mix everything together well.

Reduce the heat to low and allow the mixture to simmer for 5-7 minutes, stirring occasionally, until the sauce thickens and the flavors meld together. The filling should be rich, saucy, and aromatic.

Step 3: Assemble the Garlic Bread Sloppy Joe Melts

Take your prepared garlic bread halves and place them on a baking sheet. Spread the Sloppy Joe mixture evenly over both halves of the bread, ensuring the mixture is piled high for maximum flavor.

Step 4: Add the Cheese

Sprinkle the shredded mozzarella and sharp cheddar cheeses evenly over the top of the Sloppy Joe-covered bread. The combination of cheeses gives these melts an ooey-gooey texture and sharp, rich flavor.

Step 5: Bake the Sloppy Joe Melts

Place the assembled garlic bread halves into the preheated oven. Bake for 12-14 minutes, or until the cheese is melted, bubbly, and golden brown. You want the bread to be slightly crispy on the edges, and the cheese should be completely melted and irresistible.

Step 6: Garnish and Serve

Once the cheese is beautifully golden and bubbly, remove the melts from the oven. Let them cool for 2-3 minutes. Garnish with freshly chopped parsley for a pop of color and freshness.

Slice the garlic bread into individual servings (you can cut them into squares or strips) and serve immediately. These melts are best enjoyed warm when the cheese is gooey and the bread is crispy.
