Identify whether you need Cuban bread for a pressed sandwich or for baking (loaf/roll texture matters).
Choose the substitute that matches your goal: crisp crust (baguette/Italian loaf/bolillo) or convenience (hoagie rolls).
Slice in the same thickness as Cuban bread; for crusty swaps, toast cut sides briefly to prevent sogginess.
For softer bread swaps, add crispness by pressing in a hot skillet for 1–2 minutes per side or using a quick broil.
Let the assembled sandwich rest 2–3 minutes before biting so the crumb firms up and flavors redistribute.
