Cut the bread into bite-sized chunks and set aside.
Heat the skillet over medium heat and melt the butter, allowing it to sizzle gently and become fragrant.
Add the minced garlic to the skillet and cook for about 30 seconds, stirring constantly until the garlic is golden and releases a toasted aroma.
Place the bread chunks into the skillet, tossing or turning them to coat evenly with the garlic butter.
Cook the bread, stirring occasionally, until the edges are golden brown and crispy, about 5 minutes.
Sprinkle the grated Parmesan cheese over the bread and cook for another 1-2 minutes until the cheese melts and forms a crust.
Remove the skillet from the heat and transfer the garlic Parmesan bread bites to a serving plate.
Serve immediately while still warm, allowing the crispy edges, fragrant garlic, and cheesy topping to be fully appreciated.
