Pataniscas de bacalhau turn dense and greasy when the batter is treated like a thick fritter mix: it should fall slowly from a spoon, not hold its shape. Properly desalting the cod and frying small portions in hot oil keeps the edges crisp while the centre stays tender.
Pataniscas de bacalhau are Portuguese cod fritters made with shredded salt cod in a loose batter of flour, egg, onion and parsley—not potato croquettes like pastéis de bacalhau. Desalt the cod for 24–48 hours, then fry spoonfuls at 170–175°C in batches for a moist centre and lightly crisp, golden edges.
Follow the process and plan the cod
Plan the cod soaking and use 250 g desalted cod, 120 g flour, 2 eggs, cold water, onion and parsley for about 12 small fritters.
Shop for cod that suits fritters
For a reliable batch of Portuguese cod fritters, use 250 g of desalted, shredded cod, 120 g flour, 2 eggs, 1 small very finely chopped onion, 2 tablespoons chopped parsley and about 150 ml cold water, added gradually. After desalting the salt cod by soaking it in cold water and poaching it briefly, let the fish cool before combining it with the vegetables. Whisk the flour, eggs and most of the water until smooth, then fold in the cod.
The bacalhau batter should be a loose fritter batter: it should fall in a slow ribbon, carrying visible fish strands, rather than sit in a mound on the spoon.
See the whole route before frying
- Soak the salted cod cold: match the soaking time to the thickness of the piece.
- Cook and flake it: poach briefly, remove bones and cool the strands.
- Mix a loose batter: aim for a slow, thick ribbon falling from the spoon.
- Fry small spoonfuls: hold the oil between 170 and 175°C.
- Drain and serve: eat while the edges are still crisp.
What you are looking for: cod strands held in a batter that falls slowly, spreads only a little in the oil, and forms a thin fritter. A thick scoop is not a better scoop.

Desalt the bacalhau by thickness
Soak the cod in cold water by thickness, changing it every 6 to 8 hours, until a cooked flake tastes pleasantly seasoned rather than bland or aggressively salty.
Use this cold-water schedule
| Cod piece | Cold soaking time | Change water |
|---|
| Flakes or thin cuts | 18 to 24 hours | Every 6 to 8 hours |
| Medium fillets | 24 to 36 hours | Every 8 hours |
| Thick loin pieces | 36 to 48 hours | Every 8 hours |
Poach briefly and test it
For dependable pataniscas, desalt thin cod for roughly 24 hours and thick pieces for 36 to 48 hours, changing cold water regularly. Then taste a cooked flake before seasoning anything else. A loose batter cannot hide over-salted fish, while slightly under-seasoned cod can be corrected with a pinch of salt after the first test fritter.
Mix a batter that falls slowly
Whisk flour, eggs and cold water, then fold in cooled cod, onion, parsley and pepper until the mixture drops from a spoon in a slow, thick ribbon.
Check the ribbon, not only grams
| What you see | What it means | Fix now |
|---|
| It spreads like a crêpe | Too thin | Whisk in 1 teaspoon flour, wait 2 minutes |
| It falls as one lump | Too thick | Add 1 tablespoon cold water or milk |
| It falls in a slow ribbon | Correct texture | Fry one test fritter |
Make the first fritter your test
Fry one tester before adjusting pepper or salt.
Fry in batches, serve and save leftovers
Keep the oil hot enough
Fry tablespoon-sized portions at 170 to 175°C in small batches until deep golden and lacy at the edges, allowing the oil to recover between batches.
Pair, store and reheat properly
⚠️ Do not reheat fritters in a microwave if crispness matters. It warms the centre but turns the fried surface soft.
Cool cooked pataniscas completely on a rack before storing them, so trapped steam does not soften the crust. Refrigerate them in an airtight container for up to 2 days, ideally with a sheet of paper towel underneath, and reheat in a 200°C oven or air fryer for 5 to 8 minutes until hot and crisp. For longer storage, freeze the cooled fritters in a single layer until firm, then transfer them to a freezer bag for up to 2 months.
Reheat from frozen at 200°C for about 10 to 14 minutes, turning once; this dry heat restores crispy fritter edges far better than a microwave.
Serve pataniscas as Portuguese seafood snacks with lemon wedges and a simple tomato-and-onion salad, or make them part of a fuller meal with arroz de feijão, tomato rice or a loose-style bean rice. A traditional pataniscas à antiga approach keeps the fritters thin, irregular and rich in visible cod strands, onion and parsley rather than shaping them into neat cakes. Some family versions use a little milk instead of part of the water for a softer centre, while others add a pinch of piri-piri or finely sliced spring onion.
None of these variations turns them into pastéis de bacalhau: the defining feature remains the thin flour batter rather than a potato mixture.
Your questions answered
Can I make pataniscas with fresh cod?
Yes, you can use 250 g cooked fresh cod, but add a small pinch of salt after tasting. Fresh cod lacks the cured flavour and firm flakes of bacalhau, so the result is milder.
Why are my fritters oily?
Oily fritters usually mean the oil was below 170°C or the pan was overcrowded. Fry 4 to 6 small portions at once and wait 1 to 2 minutes between batches.
Why is my batter too runny?
Runny batter spreads immediately in the oil and needs flour in small additions. Whisk in 1 teaspoon at a time, wait 2 minutes, then repeat the spoon-ribbon test.
Why are my fritters raw in the middle?
A raw centre usually comes from batter that is too thick or fritters that are too large. Loosen the batter with 1 tablespoon cold water and use tablespoon-sized portions.
Can I prepare the batter ahead?
You can prepare the cod and chopped herbs up to 24 hours ahead in the fridge. Mix the final batter no more than 30 minutes before frying because onion releases water over time.
Are pataniscas and pastéis the same thing?
No, pataniscas are thin flour-batter fritters, while pastéis are potato-and-cod croquettes. Their shape, texture and frying behaviour are different.
The essentials:- Desalt by thickness, usually between 24 and 48 hours, then taste the cooked cod.
- Keep the batter loose enough to fall in a slow, thick ribbon from the spoon.
- Fry small batches at 170 to 175°C so the edges crisp before the centre dries.
- Choose pastéis, not this recipe, when you want potato-based cod croquettes.
