Preheat oven to 350F. Line a small baking sheet with foil and set aside.

Cut the top of the bread bowl off and set aside. Place the brie on the bread and use a paring knife to cut into the bread around the cheese (to create the hole for the cheese). Cut about an inch into the bread. Use your fingers to hollow out the hole for the brie. Use the knife to cut slits around the perimeter of the bread, but be sure not to cut all the way to the middle. Leave a bit of bread as to keep the shape in tact. You will tear off these pieces later to dip into the cheese.

Mix the melted butter and garlic salt in a small bowl. Drizzle the butter over the bread bowl, onto the sides and into the middle. Sprinkle with more herbs if you have favorites.

Set the brie down into the bread bowl (make sure you've removed the casing). Top with the walnuts and bacon and then mozzarella. Top with the top of the bread.

Bake for 20-30 minutes until the bread is crispy and toasted and the cheese is fully melted. Once you remove the top, you can garnish with more walnuts and bacon.

Tear off the side pieces of bread and dip into the cheese for the perfect appetizer!
