Zusatztipps für die Zubereitung

To ensure the best result, use sardines packed in high-quality olive oil and drain them well before assembly to keep the bread crisp. The garlic rubbing technique works best when the bread is straight out of the oven, as the heat helps the garlic melt into the toasted surface.

Varianten und Anpassungen

For a richer version, try adding a light smear of softened butter or creamy ricotta to the bread before placing the sardines. If you want to experiment with different fish, you can easily substitute the sardines with smoked mackerel or salty anchovies for a unique twist.

Serviervorschläge

These crostini are best served immediately while the baguette is still warm and crunchy. To complete the experience, pair this appetizer with a crisp, chilled white wine such as Verdicchio or Pinot Grigio, which beautifully cuts through the richness of the sardines.
