Croquetas: Spain's Béchamel Croquettes, Why They Are Made With Béchamel (Not Mashed Potato), the Correct Texture for the Filling, and Why They Must Be Served Hot

Croquetas are one of the essential items of the Spanish tapas tradition — they appear on virtually every tapas bar menu in the country, they are made at home for large gatherings, and their quality is used as a reliable measure of a kitchen's skill. A croqueta that is too firm (overcooked béchamel, too much flour, too long in the refrigerator) is immediately obvious; a croqueta that has a flowing, creamy center that pours slightly when cut open is the standard to aim for.

The dish entered Spain through French culinary influence in the 18th and 19th centuries — croquettes are French in origin, and the béchamel base reflects this — but Spain transformed the dish into something distinctively its own by using jamón ibérico as the primary filling and developing a standard for the flowing, creamy interior that French croquettes do not require.

Why Béchamel (Not Mashed Potato)

Portuguese and some other European croquettes use mashed potato as the base — these produce a firmer, denser croquette that holds its shape at room temperature. Spanish croquetas use béchamel because:

1. The goal is a flowing interior — béchamel, when cooked to the right thickness and then reheated, flows; mashed potato does not
2. The texture is creamier — the milk fat in béchamel produces a silky, rich mouthfeel
3. The flavor is more neutral — béchamel's mild flavor lets the jamón, chicken, or salt cod filling shine through

The Béchamel Thickness Requirement

The béchamel for croquetas is cooked to a much thicker consistency than regular béchamel sauce — it must hold its shape when a spoon is dragged through it and will be almost as thick as mashed potato when hot. This is necessary because:

1. After chilling overnight, it must be firm enough to shape into ovals without collapsing
2. During frying, the hot oil must not blow through the crust before the interior reaches temperature

Thickness test: The béchamel is done when it pulls cleanly away from the sides of the pan, a spoon drawn across the surface holds a clean trail for several seconds, and when spread on a plate it does not flow. This typically takes 15–20 minutes of cooking after adding the milk, stirring constantly.

The Complete Recipe

Makes: 20–24 croquetas | Time: 1 hour + overnight chilling

Ingredients

Béchamel filling:

• 100g unsalted butter
• 120g all-purpose flour
• 800ml whole milk (warm)
• 150g jamón ibérico or jamón serrano, very finely diced (or 150g cooked chicken, finely shredded)
• ½ onion, very finely minced
• Pinch of nutmeg
• Salt and white pepper

Coating:

• 2 eggs, beaten
• 150g fine dry breadcrumbs (pan rallado)
• Sunflower oil for deep frying

Method

1. Cook the onion: Melt butter in a heavy saucepan over medium heat. Add minced onion; cook 8–10 minutes until very soft and translucent (not colored).

2. Make the béchamel: Add flour to the butter-onion mixture; stir over medium heat for 2 minutes to cook out the raw flour taste. Add warm milk in a slow, steady stream, whisking constantly. Cook over medium heat, stirring constantly, 15–20 minutes until the béchamel is very thick — it should pull away from the sides of the pan cleanly. Add jamón (or chicken); season with nutmeg, salt, and white pepper.

3. Chill: Pour onto a lightly oiled tray to a depth of 3–4cm; cover with plastic wrap pressed directly against the surface (prevents a skin forming); refrigerate overnight (minimum 4 hours, overnight is better).

4. Shape: With wet hands or two spoons, scoop portions of the cold béchamel and shape into oval cylinders (approximately 5–6cm long). Work quickly — they will soften.

5. Coat: Roll each croqueta in beaten egg, then in breadcrumbs, pressing to adhere. For extra crispiness, coat twice (egg → breadcrumb → egg → breadcrumb).

6. Fry: Heat oil to 180°C. Fry croquetas in small batches, 2–3 minutes, until golden brown all over. Do not crowd the pan — temperature drops too much.

7. Serve immediately — the interior should be very hot and flowing.
