Jamon croquetas are small, breaded and fried rolls built from a thick bechamel sauce studded with diced Spanish ham. You make them by cooking a very thick white sauce with ham and onion, chilling it until firm, then shaping, breading, and frying it into crisp, creamy bites.
Croquetas are a fixture of Spanish tapas bars and home kitchens alike, born as a practical way to use up leftover ham from a jamon leg. A good one has a shatter-crisp shell around a filling so soft it almost pours when you cut in.

What Actually Matters
The bechamel has to chill for real, at least 4 hours, ideally overnight, until it is completely firm and cold. A warm or under-chilled filling will not hold its shape through breading and will burst open in the fryer. Cold, firm filling is what lets you get a clean fry with an intact, molten center.
Jamon Croquetas Recipe
Serves 4. Prep time: 30 minutes, plus 4 hours chilling. Cook time: 25 minutes. Total time: 4 hours 55 minutes.
- 4 tablespoons unsalted butter
- 1/2 cup all-purpose flour, plus more for dredging
- 2 cups whole milk, warmed
- 1/2 cup finely diced onion
- 4 ounces Spanish jamon or prosciutto, finely diced
- 1/4 teaspoon ground nutmeg
- 1 teaspoon kosher salt, plus more to taste
- 2 large eggs, beaten
- 1 cup panko breadcrumbs
- Vegetable oil, for frying
- Melt the butter in a saucepan over medium heat. Add the onion and cook for 4 minutes until soft.
- Stir in the flour and cook for 2 minutes, stirring constantly, to cook out the raw flour taste.
- Slowly whisk in the warm milk, a little at a time, until you have a thick, smooth paste with no lumps.
- Stir in the jamon, nutmeg, and salt. Cook for 3 to 4 minutes, stirring, until very thick.
- Spread the mixture into a shallow dish, cover, and chill for at least 4 hours, ideally overnight.
- Shape the chilled mixture into small logs, about 2 inches long.
- Dredge each log in flour, dip in beaten egg, then coat in panko breadcrumbs.
- Heat 2 inches of vegetable oil to 350 degrees F. Fry the croquetas in batches for 2 to 3 minutes, until golden brown.
- Drain on paper towels and serve immediately.

Tips, Variations, and Storage
Chicken, mushroom, and cod are all common croqueta fillings if you want a variation. You can freeze shaped, breaded croquetas raw for up to 2 months and fry them straight from frozen, adding an extra minute of frying time. Cooked croquetas do not reheat well in a microwave, use an oven instead.
Frequently Asked Questions
Why is my filling too runny to shape?
It likely needs more chilling time, or the bechamel wasn't cooked thick enough before chilling.
Can I freeze croquetas?
Yes, freeze them breaded and raw, then fry straight from frozen.
What ham should I use?
Spanish jamon serrano or jamon iberico if you can find it. Prosciutto is a reasonable substitute.
Why did my croquetas burst in the oil?
The filling was too warm or the breading had a gap. Make sure the coating fully seals the log.
Can I bake instead of fry?
You can bake at 425 degrees F with a light oil spray, but the texture is noticeably less crisp.
