Summary: "Bacallà a la llauna" is one of the emblematic dishes of Catalan cuisine. Its name comes from the "llauna" — the metal tray where it was traditionally baked in Catalan homes. It's a deceptively simple dish: cod, olive oil, garlic, paprika, and an oven. But precisely this simplicity demands top-quality ingredients and precise technique.
What Makes Authentic Bacalao a la Llauna Special
Bacallà a la llauna is one of the emblematic dishes of Catalan cuisine. Its name comes from the llauna — the metal tray where it was traditionally baked in Catalan homes. It's a deceptively simple dish: cod, olive oil, garlic, paprika, and an oven. But precisely this simplicity demands top-quality ingredients and precise technique.
The difference between a mediocre bacalao a la llauna and a memorable one lies in three details: the quality of the cod (thick loin, well desalted), the exact baking point (so it remains juicy inside and golden outside), and the base "sofregada" (sauté) that gives it depth.
Ingredients for 4 people
The cod
- 4 desalted cod loins, 180-220g each (skin on, boneless)
- Ideal thickness: 3-4 cm — if thinner, it dries out; if thicker, it won't cook through
- Preferably Icelandic cod (firm texture, bakes well)
The Sofregada (Sauté)
- 6-8 cloves of garlic (sliced, not pressed)
- 1 tablespoon of sweet paprika from La Vera (or ñora paprika)
- 100 ml of extra virgin olive oil
- 1 bay leaf
- Optional: 1 dried chili
Complements
- Flour for dredging (optional, classic version doesn't use it)
- Fresh chopped parsley for serving
- Half a lemon
Step-by-Step: The Recipe
1. Prepare the sofregada (10 min)
In a large pan, heat the olive oil over medium-low heat. Add the sliced garlic and brown it slowly — it should be golden but never burnt (if burnt, it will bitter the entire dish). Once golden, remove from heat, wait 30 seconds, and add the paprika. Never add paprika to boiling oil — it burns instantly and tastes bitter.
2. Prepare the cod
Pat the loins dry with kitchen paper — surface moisture prevents them from browning properly. If you want the version with flour: lightly flour only the flesh side (not the skin) and shake off any excess.
3. Assemble in the tray (llauna)
Preheat the oven to 220°C (top and bottom heat). Grease the baking tray with a little of the sofregada. Place the loins skin-side down. Pour the rest of the sofregada (oil + garlic) over the loins.
4. Baking: the critical moment
Place the tray in the middle-upper part of the oven:
- 3 cm loins: 12-15 minutes
- 4 cm loins: 15-18 minutes
- 5 cm loins: 18-22 minutes
The cod is ready when the surface is slightly golden and, when pressed with a finger, it yields slightly but springs back to its shape. If it's very firm, it's overcooked.
5. Serve immediately
Bacalao a la llauna doesn't wait. Serve directly in the baking tray (the "llauna") with chopped parsley on top and a squeeze of lemon on the side. Accompany with "patatas panaderas" (baker's potatoes), escalivada, or simply bread for dipping in the oil.

Mistakes That Ruin the Dish
- Cod too thin: below 2.5 cm, it dries out in the oven. Always ask for thick loin.
- Burnt paprika: if the oil is smoking before adding the paprika, discard it and start again.
- Oven too low: below 200°C, the cod steams instead of roasts, becoming moist and pale.
- Overcooking: better one minute less than one minute more. Cod continues to cook outside the oven with residual heat.
- Not drying the cod: surface moisture creates steam instead of browning.
The Wine: What to Pair With It
Bacalao a la llauna calls for a full-bodied white wine or a light young red:
- White: White Grenache from Penedès, Xarel·lo with aging, or Macabeo from Terra Alta
- Red: Young Grenache from Priorat, light Monastrell, or a Mencía from Bierzo
- Rosé: a dry Grenache rosé works perfectly in summer
Legitimate Variations
- With raisins and pine nuts: add a handful of soaked raisins and toasted pine nuts — a Catalan Christmas version
- With tomato: a base of tomato sofrito under the cod — a saucier version
- A la llauna with samfaina: a bed of Catalan ratatouille (eggplant, peppers, onion) under the cod

Frequently Asked Questions
Can I use fresh cod instead of desalted?
Yes, but the result is different. Desalted cod has more gelatin and a richer texture than fresh cod. If using fresh, lightly salt 30 minutes before cooking.
Can it be cooked in a frying pan instead of the oven?
Technically yes (it's called "pan-fried cod with sofrito"), but it's not bacalao a la llauna — the oven provides an enveloping golden finish that a frying pan cannot achieve.
How much does this dish cost to make?
With premium desalted cod: about €8-10 per person in raw materials. It's an accessible luxury dish — expensive product but simple preparation and spectacular results.
