Heat the crust and cheese together.

A skillet or oven gives the crust more time to crisp. A microwave is faster but needs a shorter cycle.

Skillet

Put a slice in a dry skillet over low to medium heat. Cover loosely so the cheese warms while the base crisps. Check often to avoid scorching.

Place slices on a baking sheet in a preheated oven. Moderate heat gives the center time to warm before the crust gets too dark.

Use short cycles and check between them. The crust will be softer, but the method is fast.

USDA guidance says to reheat leftovers to 165 F. Use a food thermometer when safety is uncertain. Read the USDA leftovers guidance.
