Extra Tips For the best flavor, use a mix of mushrooms such as cremini, shiitake, and oyster, and avoid overcrowding the pan so they brown instead of steam. Day-old baguette works especially well because it toasts up crisp without becoming tough. You can toast the crostini in advance and re-crisp them in a hot oven for a few minutes just before topping. Adjust the garlic and herbs to your taste and feel free to add a pinch of red pepper flakes for gentle heat. If serving for a party, keep the mushroom topping warm in a covered pan over low heat and assemble crostini in small batches so the bread stays crunchy and the topping stays juicy.
