The Manchegan stew that was born from atascaburras

In La Mancha, when Lent arrives, a version of Lenten stew is cooked that is unlike any other. It doesn't contain chickpeas. It doesn't contain spinach. And it doesn't contain noodles. It contains potato, cod, garlic, and walnuts.

It is the stewed cousin of the classic atascaburras, that rustic potato and cod puree that is eaten cold. But the Manchegan Lenten stew version is served hot, with more broth, and is often enriched with hard-boiled egg and local olive oil.

The original name in many towns in Ciudad Real and Albacete is "potato and cod stew" or simply "Good Friday stew." But the base is the same as atascaburras: mashed potato that melts with shredded cod into a comforting dish.

Differences with classic atascaburras

If you already know our atascaburras recipe, you might wonder: isn't it the same? Not exactly.

  • Classic atascaburras: served cold or warm. The potato is mashed with the cod until a thick cream is obtained. It's seasoned with olive oil, raw garlic, and walnuts. It's a snack or tapa.
  • Manchegan Lenten stew: served hot, with broth. The potatoes are cut into pieces (not puréed), the cod is added in chunks, and the whole is cooked like a stew. It includes a sofrito with onion and paprika. It's a spoon-friendly first course.

Both share ingredients, but the texture and presentation are different. The stew is more comforting, ideal for cold March days. Atascaburras is fresher, more direct.

Ingredients for 6 people

  • 1 kg potatoes (preferably Monalisa or Kennebec)
  • 400 g desalted cod in chunks
  • 1 medium onion
  • 4 cloves garlic
  • 1 teaspoon sweet paprika
  • 1 bay leaf
  • 100 g shelled walnuts
  • 3 eggs
  • Extra virgin olive oil — 5 tablespoons
  • Salt and black pepper
  • 1.5 liters water

Optional: a pinch of ground cumin and a few saffron threads.

Step-by-step preparation

1. The Manchegan sofrito (8 minutes)

Finely chop the onion. Slice the garlic. In a wide pot, heat the oil and sauté the onion for 5-6 minutes. Add the garlic and cook for 1 more minute. Remove from heat, add the paprika, stir quickly, and return to low heat.

2. The potatoes (25 minutes)

Peel the potatoes and break them (don't cut them cleanly: break them with the knife so they release starch and thicken the broth). Add them to the pot with the sofrito. Cover with 1.5 liters of cold water, add the bay leaf, and bring to a boil.

Lower the heat and cook for 20-25 minutes until the potatoes are tender. Mash some with a fork against the side of the pot to thicken the broth. Leave others whole for texture.

3. The cod (10 minutes)

Add the desalted cod chunks to the stew. Cook for 8-10 minutes over low heat. Do not stir too much; the cod should remain in pieces.

4. The walnuts and egg

While the cod is cooking, boil the eggs for 10 minutes. Peel them and cut them into quarters. Roughly chop the walnuts (don't crush them; they should provide texture).

5. Serving

Divide the stew into deep plates. Place the hard-boiled egg quarters and chopped walnuts on top. Drizzle with a generous stream of raw extra virgin olive oil.

This stew is good freshly made, but the next day the potatoes have absorbed all the flavor and it's even better. Reheat it over low heat with a splash of water if it has thickened too much.

Tips for the perfect Manchegan stew

  • Breaking the potatoes. This is the quintessential Manchegan trick. Don't cut them cleanly with a knife: make a partial cut and break the piece with your hands or by twisting the knife. The rough edges release starch and give body to the broth.
  • Quality walnuts. Use fresh, not rancid, walnuts. If you can, get local (Castilian) walnuts. Lightly toast them in a dry pan for 2 minutes to intensify their flavor.
  • Add cod at the end. It only needs 8-10 minutes. If you cook it with the potatoes from the beginning, it will fall apart.
  • Raw olive oil. The drizzle of oil when serving is not decoration. It's part of the dish. Use a good extra virgin olive oil from La Mancha, which has character and personality.

Where this recipe comes from

La Mancha is a dryland. Winters are long and cold. Potatoes, salted cod, and walnuts were ingredients that could be stored for months. They didn't need refrigeration, didn't spoil, and were very filling.

The original atascaburras was shepherd's food. They prepared it in the field with what they had on hand: potatoes boiled in water, shredded cod, and walnuts from their pockets. The name comes from "atasca" (thickens) and "burras" (a reference to the dense, mud-like texture). A dish that clogs you up, that fills you.

Over time, Manchegan cooks refined it for the Holy Week table. They added sofrito, broth, hard-boiled egg, and turned it into this Lenten stew that we are now bringing back.

Frequently asked questions about Manchegan Lenten stew

Is it the same as atascaburras?

Not exactly. They share ingredients (potato, cod, walnuts), but atascaburras is a puree served cold or warm, while Manchegan stew is a hot stew with broth. You can see our classic atascaburras recipe to compare.

Can I add chickpeas?

It's not traditional, but no one will forbid you. If you add them, you'll be getting closer to an Andalusian stew. The beauty of the Manchegan version is that the potato serves as the base instead of legumes.

What type of potato works best?

Floury potatoes (like Kennebec) break down more and thicken the broth better. Waxy potatoes (like Monalisa) hold their shape. The ideal is to mix: some that break down to give body and others that remain whole.

Can I use salted cod?

Yes, desalinate it for 48 hours in cold water, changing the water every 8 hours. Already desalted cod is more convenient and guarantees a balanced salt level.

What wine pairs with this stew?

A young, very cold Airén white wine from La Mancha. Or if you prefer red, a young Tempranillo from Valdepeñas served fresh (14-15 °C).
