Can I make this ahead?
Prepare the sardine mixture up to 2 hours ahead and refrigerate. Toast and assemble just before serving to prevent sogginess.
What type of bread works best?
Crusty sourdough, ciabatta, or whole grain bread holds up best to the sardine mixture and olive oil without falling apart.
How do I reduce the fishiness?
Use sardines packed in oil rather than mustard or tomato sauce, and ensure the lemon juice is generous—it brightens and masks strong fish flavor.
Is this recipe gluten-free?
Only if you use gluten-free bread. All other ingredients are naturally gluten-free.
Can I skip the hot cherry peppers?
Yes. Substitute with jalapeño, red pepper flakes, or sriracha for heat, or omit entirely for a mild version.
