Start by melting 2 sticks of unsalted butter in a small saucepan over low heat. Once melted, remove from heat and mix in the finely grated garlic cloves and minced parsley. Stir until well combined. The aroma will be heavenly!
Take your large loaf of fresh baked bread and slice it in half lengthwise. This will create two open faces for the cheesy goodness to rest upon.
Using your butter knife, generously spread the garlic butter mixture over the cut sides of the bread. Make sure to cover every nook and cranny to ensure each bite is packed with flavor.
Sprinkle the shredded fontina cheese evenly over the buttered bread, followed by the asiago cheese. Feel free to be a little generous here; after all, this is cheesy bread, and more cheese is always better!
Sprinkle coarse salt and fresh cracked pepper over the cheesy layers. This will enhance the flavors and add a lovely contrast to the richness of the cheeses.
Preheat your oven to 375°F (190°C). Place the loaded bread halves on a baking sheet and bake for about 15-20 minutes, or until the cheese is bubbly and golden brown. If you like it extra crispy, you can broil it for the last minute or two—just keep an eye on it!
Once your cheesy bread is out of the oven, let it cool for a couple of minutes before slicing into portions. Serve warm and watch it disappear in no time.
