Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
Prepare the Garlic Butter: In a small bowl, mix together the softened butter, minced garlic, garlic powder, dried parsley, dried oregano, dried basil, and salt until well combined.
Prepare the Bread: If using a loaf of French bread, slice it into 1-inch thick slices. If using Texas toast bread slices, proceed to the next step.
Spread the Butter: Spread a generous amount of the garlic butter mixture onto one side of each bread slice, ensuring the butter reaches the edges.
Add the Cheese: Sprinkle a generous amount of shredded mozzarella, shredded cheddar, and grated Parmesan cheese on top of the buttered side of each bread slice.
Bake: Place the prepared bread slices on the lined baking sheet in a single layer. Bake in the preheated oven for 10-12 minutes, or until the cheese is melted and bubbly, and the edges of the bread are golden brown.
Broil (Optional): For an extra crispy top, you can turn on the broiler for the last 1-2 minutes of baking. Keep a close eye on the bread to prevent burning.
Garnish and Serve: Remove the cheesy Texas toast from the oven and sprinkle with fresh chopped parsley if desired. Serve warm.
