Champiñones rellenos de jamón are Castilian bar cooking: mushroom caps, a small jamón sofrito, and quail egg, with one rule that matters. Roast the caps first so they give up their water.

Champiñones rellenos de jamón are Castilian bar cooking, from the inland larder that knows what to do with mushrooms, garlic, parsley, and a little cured ham. They are not a grand dish. Good. A mushroom cap holds a spoon of jamón sofrito, the slow onion base, and a quail egg sets on top just enough to tremble. That is plenty.

The method that decides them is not the filling. It is the mushroom. Roast the caps hollow-side down first, so they shed their water before you ask them to hold anything. Skip that and the tray floods, the filling slides, and you get a damp mouthful instead of a firm one. Ten minutes now saves the whole dish later.

If you are far from Spain, use a dry-cured ham cut thin and chopped small, not smoked ham. Prosciutto works at a pinch, though it is sweeter and softer than jamón serrano, so use a little less salt. No quail eggs where you are? Beat one hen's egg with a pinch of salt and spoon a teaspoon over each cap. It will not have the same little yolk, but it will set and hold the filling.

Keep the sofrito low until the onion is dark gold and sticky, then fold in the mushroom stems and jamón. My Margin beside this one says only, "cap primero," cap first. Sensible woman. Siempre sale, si lo sigues.

Stuffed mushrooms belong naturally to Castilian bar cooking, especially the inland belt where cultivated champiñones and cured pork meet the garlic-and-parsley habits of the home kitchen. La Rioja and Castilla both have strong mushroom traditions, with simple bar servings built around the cap, the plancha, and a small salty filling rather than heavy sauces. The quail egg is a later but familiar bar finish, useful because its size fits the mushroom without drowning it.

The technique, the tradition, and the story behind every dish.

Equipment Needed

  • Rimmed baking tray
  • Small frying pan
  • Small cup for cracking quail eggs
  • Paring knife

Instructions

  1. 1

    Prepare the caps

    Heat the oven to 200C. Wipe the mushrooms clean with a damp cloth, pull out the stems, and finely chop the stems for the filling. Toss the caps with 1 tablespoon of olive oil, 1/4 teaspoon salt, and a little black pepper. Set them hollow-side down on a baking tray.

  2. 2

    Roast them dry

    Roast the caps hollow-side down for 10 minutes, until they have relaxed and given off their water. Lift them to a plate, pour the liquid off the tray, and turn the caps hollow-side up. This is the step that keeps the mushrooms firm instead of watery. Do it now and they behave later.

    If the caps are very large and wet, give them 2 more minutes hollow-side down. Mushrooms vary. The tray should not be swimming when you fill them.
  3. 3

    Cook the sofrito

    Warm 2 tablespoons olive oil in a frying pan over medium-low heat. Add the onion with a pinch of salt and cook 10 to 12 minutes, stirring often, until it turns dark gold and sticky. Add the chopped mushroom stems and cook another 5 minutes, until their water has gone. Add the garlic and cook 1 minute more, just until it smells sweet.

  4. 4

    Finish the filling

    Stir in the chopped jamón and cook 1 minute, no longer; jamón toughens if you punish it. Add the wine and let it bubble until the pan is nearly dry. Take the pan off the heat and stir in the breadcrumbs, parsley, sweet pimentón, and a few turns of black pepper. Taste before salting again, because the jamón may have done the work for you.

  5. 5

    Fill the mushrooms

    Spoon the filling into the roasted caps, pressing it in gently but not packing it hard. Make a small hollow in the centre of each one for the egg. Crack each quail egg into a small cup first, then slide it onto a mushroom; quail shells are tough and a knife tip helps open them cleanly.

  6. 6

    Bake to set

    Return the tray to the oven and bake 6 to 8 minutes, until the whites are just set and the yolks are still soft. Watch closely at the end. A quail egg goes from tender to chalky while you are looking for a clean towel.

  7. 7

    Serve at once

    Finish with a little chopped parsley and a few drops of olive oil. Serve warm, with bread nearby for the oil and the bits of jamón that fall onto the plate. These wait badly, so bring them out as soon as the eggs set.

Chef Tips

  • Choose mushrooms with deep caps, about 4 to 5cm across, so they can hold the filling and the quail egg. Flat caps are fine for the plancha, not for stuffing.
  • Use jamón serrano or another Spanish dry-cured ham. If you use prosciutto, chop it small and salt carefully at the end; it is softer and sweeter, so the filling will taste less firm and porky.
  • Do not wash mushrooms under running water unless they are truly dirty. Wipe them clean. They already carry enough water, and the first roast is there to drive that water out.
  • No quail eggs? Beat 1 large hen's egg with a pinch of salt and spoon about 1 teaspoon over each filled cap. It will set like a small glaze rather than giving you a separate yolk.
  • For drinking, pour a young Rioja, a dry fino, or a small beer. The salt of the jamón wants something dry beside it.

Advance Preparation

  • Roast the mushroom caps and make the jamón filling up to 6 hours ahead. Keep them separate in the refrigerator, then fill and bake with the quail eggs just before serving.
  • Do not bake the eggs ahead. They overcook when reheated, and the dish loses the soft yolk that makes it worth serving.
