FAQ
Can I make this without Parmesan cheese?
Yes, you can use plain butter, but the Parmesan adds extra flavor and helps create a crispier crust. Try adding garlic powder for extra taste.
What if I don't have sourdough bread?
Any thick bread works well - try brioche, Texas toast, or regular white bread. Avoid thin sliced bread as it may get soggy.
How long does this keep?
Grilled cheese is best eaten immediately. Leftovers can be refrigerated for 2 days and reheated in a skillet or toaster oven until crispy again.
