Anchovy and butter crostini

June 8, 2026María José Sáez⏱ 2 min de lectura

Toasted bread, good butter, and a Cantabrian anchovy on top: the anchovy crostini proves that simplicity, with excellent ingredients, is a luxury. The fresh fat of the butter envelops the salty and unctuous flavor of the anchovy, creating a bite that is served in the best pintxo bars and that you can make at home in two minutes.

In France, the combination of butter with anchovy is a classic that seems contradictory but works extraordinarily well. The milky fat of the butter softens the saltiness of the anchovy and creates a well-rounded, creamy bite with a depth of flavor you wouldn't expect from two such simple ingredients. It's the Parisian bistro appetizer: elegant without pretension, sophisticated without complications. An anchovy fillet on buttered bread, black pepper, and nothing else.

Ingredients

Step-by-step preparation

  1. Lightly toast the baguette slices: golden on the outside, soft on the inside. If you toast them too much, the bread will be too crunchy, and the butter won't penetrate.
  2. Spread each slice with a generous layer of butter at room temperature. The butter should be soft and spreadable, not melted or cold from the fridge. A 2-3mm layer is ideal.
  3. Place an anchovy fillet on top of the butter, slightly curved, without flattening it.
  4. Finish with freshly ground black pepper. If you want a touch of freshness, add a pinch of lemon zest — not juice, just zest: the acid from the juice oxidizes the butter.

The house trick

Use the best anchovy you have for this recipe: "00" Selection if possible. When a dish is this simple, the quality of each ingredient is 100% noticeable. A mediocre anchovy on butter and bread is still a decent bite, but an exceptional anchovy on good butter is an experience. It's the difference between eating and savoring.

Frequently asked questions

Salted or unsalted butter?

Unsalted or high-quality sweet butter is best, as the anchovy already provides saltiness. Good French or grass-fed butter elevates the bite.

What anchovy to use?

A Cantabrian anchovy in oil, size 00 or 0. In such a simple bite, the quality of the anchovy is everything.

What is the ideal bread?

A rustic or crystal bread, thinly sliced and toasted, to provide crunch without competing with the anchovy.
