The anchovy sandwich is not just any sandwich: it is one of the simplest sandwiches in Spanish cuisine — and one of the most misunderstood. With cheap anchovies and mediocre bread, the result is salty and monotonous. With good Cantabrian anchovies and the right bread, it's a complete gastronomic experience in less than 5 minutes. Here are the combinations that work, with exact quantities.
| Version | Ideal Bread | Anchovies per Sandwich | Flavor Profile |
|---|---|---|---|
| With grated tomato | Cristal bread / baguette | 4-6 fillets | Mediterranean, fresh |
| With butter | Baguette or rye bread | 4-5 fillets | Classic French, rich |
| With oil only | Toasted rustic bread | 5-7 fillets | Pure, anchovy protagonist |
| With pepper and egg | Sandwich bread or baguette | 3-4 fillets | Hearty, complete |
| Tapa montadito | Thin toasted bread slice | 1-2 fillets | Elegant appetizer |

Which anchovies to use: the difference between a good sandwich and a mediocre one
In an anchovy sandwich, there is no sauce or cooking to correct the flavor of the raw ingredient. The anchovy is the absolute protagonist. There are three clear categories:
| Type of Anchovy | Texture | Flavor | Result in Sandwich |
|---|---|---|---|
| Cantabrian 0/00 grade | Firm, fleshy | Balanced umami, low salt | Excellent — 4-5 fillets sufficient |
| Artisanal Mediterranean anchovy | Softer | More intense, saltier | Good — use fewer fillets |
| Industrial supermarket anchovy | Soft, breaks apart | Salty, metallic | Mediocre — you need a lot for flavor |
Size matters: grade 0 (large fillets, 6-7cm) allows for even coverage of the bread without them piling up in one spot. Small fillets of grade 4 or 5 leave gaps, resulting in uneven flavor.

The bread: the essential base
The bread in an anchovy sandwich must fulfill two functions: absorb the anchovy oil without getting soggy and provide a contrasting texture to the softness of the fillet. The best breads:
- Cristal bread (pa de cristall): the quintessential Catalan choice. Very thin and crispy crust, open crumb with large air pockets that perfectly retain grated tomato. The natural combination for a tomato and anchovy sandwich.
- Baguette: versatile for all versions. Lightly toasted in the oven or toaster, the crispy crust contrasts with the buttery anchovy.
- Rye or multi-grain bread: for the butter version. The slightly bitter and earthy flavor of rye complements the anchovy's saltiness better than white bread.
- Rustic loaf bread: for the classic sandwich with just oil. The dense crumb holds the anchovy oil well without disintegrating.
Avoid: white sandwich bread for anchovy sandwiches (too soft, poor absorption), very hard untoasted bread (the anchovy gets squashed and loses presentation).
Recipe 1: anchovy sandwich with tomato (Catalan version)
Ingredients
- 1 cristal bread (or half a baguette)
- 5-6 Cantabrian anchovy fillets
- 1 ripe tomato for grating
- Extra virgin olive oil
- Salt (a little — the anchovy is already salty)
Preparation
- Cut the bread in half and toast lightly (optional but recommended for cristal bread).
- Grate the tomato directly onto the crumb with a fine grater. The tomato should form a thin layer, not chunky pieces.
- Add a generous drizzle of olive oil over the tomato.
- Arrange the anchovy fillets in parallel lines, without overlapping. Each bite should have an anchovy.
- Optional: a few black Aragon olives or a pinch of smoked paprika.
Variation: add half an avocado in thin slices between the tomato and the anchovy. The avocado softens the saltiness and adds creaminess.
Recipe 2: anchovy sandwich with butter (French version)
Ingredients
- 1 baguette or 2 slices of rye bread
- 4-5 Cantabrian anchovy fillets
- 30g unsalted butter at room temperature
- Optional: a few drops of lemon, fresh parsley
Preparation
- Spread a generous layer of butter on the bread (untoasted for this sandwich).
- Place the anchovy fillets on the butter. The fat from the butter and the anchovy integrate, creating a rich base.
- Optional: squeeze a few drops of lemon and add chopped parsley.
This is the format served in French brasseries as an hors d'oeuvre. Simple, precise, and very effective at showcasing the quality of the anchovy.
Recipe 3: classic sandwich with oil (the purest version)
Ingredients
- Thick slices of toasted rustic bread
- 6-7 Cantabrian anchovy fillets
- Extra virgin olive oil (can be from the tin)
Preparation
- Toast the bread until it's crispy on the outside but tender on the inside.
- Drizzle with oil directly onto the toast. If you have the oil from the anchovy tin, use it: it's oil infused with all the flavor.
- Arrange the anchovies on the oil. Nothing more.
This is the version for when you want to savor the anchovy without interference. It only works with top-quality anchovies.

Ingredients
- Half a baguette
- 3-4 anchovy fillets
- 2 strips of roasted red pepper (jarred or homemade)
- 1 hard-boiled egg, sliced
- Olive oil
Preparation
- Heat or toast the bread.
- Arrange the roasted pepper as a base. Add the sliced egg and anchovies on top.
- A final drizzle of oil. The sweet-smoky pepper and egg soften the intensity of the anchovy.
Recipe 5: anchovy montadito for tapas
The appetizer version of the sandwich: thin slices of toasted bread with 1-2 anchovy fillets and some accompaniment. The best combinations:
- Anchovy + pickled chili pepper + olive: the classic gilda on bread. Spicy, salty, acidic.
- Anchovy + lemon butter + chives: elegant, for formal appetizers.
- Anchovy + cherry tomato + basil: light Mediterranean version.
- Anchovy + quail egg: a complete bite of protein and intensity.
How many anchovies per sandwich?
A common question. The answer depends on the quality of the anchovy and the size of the sandwich:
- Cantabrian anchovy grade 0 (6-7cm): 4-6 fillets for a 20cm sandwich. Quality compensates in flavor: you don't need more.
- Smaller grade anchovy (4-5cm): 7-10 fillets for the same sandwich. Smaller fillets provide less coverage.
- Montadito (small slice): 1-2 grade 0 fillets are enough for an impactful bite.
The rule: every centimeter of bread should have at least one anchovy fillet so that each bite has flavor.

Frequently asked questions about anchovy sandwiches
Can the sandwich be made with salt-cured anchovies (uncleaned)?
Yes, but it requires prior work: rinse the salt-cured anchovies under cold water to remove excess salt, fillet them by hand removing the central bone, and leave them in olive oil for 1-2 hours before serving. The result is fresher and more intense than canned anchovies, but the process is significantly more laborious.
Do anchovies in vinegar (boquerones) work for the sandwich?
Anchovies in vinegar (white boquerones) and anchovies in oil are different products. Boquerones work very well in a sandwich — fresher, more acidic, less salty. Combining both in the same sandwich (half white, half in oil) provides an interesting contrast of flavors and colors.
What to do with the leftover oil in the can?
The oil from the anchovy can is an extraordinary condiment: it has all the infused anchovy flavor. Use it to dress salads, for the sandwich bread, for pasta, or to sauté vegetables. Never throw it away.
Can the sandwich be prepared in advance?
Preferably not. The anchovy sandwich with tomato or oil will get soggy if left to sit for more than 15-20 minutes. Prepare just before consuming. If you need to prepare it in advance, store the components separately (untoasted bread, anchovies in a jar, ungrated tomato) and assemble at the last minute.
