Can I make these ahead of time?
Yes. Assemble the sandwiches, brush with garlic butter, and refrigerate for up to 4 hours. Bake directly from cold, adding 2–3 minutes to baking time.
What cheese can I use instead of provolone?
Mozzarella, fontina, or a mild cheddar work well. Avoid hard cheeses like Parmesan alone, as they don't melt evenly.
How do I know when they're done baking?
Bake until the bread is golden brown and the cheese is melted and bubbly at the edges—typically 10–12 minutes at 375°F.
Can I use garlic powder instead of fresh garlic?
Yes. Use 2 tsp garlic powder total and reduce the fresh minced garlic to 1 tsp for a subtler flavor, or omit the fresh garlic entirely.
Can this recipe be doubled?
Yes. Simply double all ingredients and bake on two sheets, rotating halfway through for even browning.
