What is Bacalhau à Lagareiro or Cod Fish Lagareiro Style?
The Bacalhau a Lagareiro, goes by many names in Portugal. It is sometimes referred to as bacalhau assado com batatas a murro or bacalhau no forno or oven baked cod.
This is one of the most famous ways of preparing codfish as it is delicious and uncomplicated.
It combines baked cod and potatoes abundantly coated with Portuguese olive oil along with onions and garlic.
The “à lagareiro” style of cooking typically refers to the abundant use of Portuguese olive oil in the recipe.
Lagar is the Portuguese word for the place where olive oil is made. And, Lagareiro is the name given to the individual who works in an olive oil mill.
This bacalhau a lagareiro recipe, not surprisingly, calls for a bathing of the cod and potatoes in luscious Portuguese olive oil.
Onions, garlic and herbs are added to the recipe and some versions even call for the addition of olives.
Once baked the result is slightly crispy potatoes, with soft onions and fish cooked to perfection.
History of Bacalhau A Lagareiro Recipe
The origin of Bacalhau a Lagareiro is controversial. However, it most likely comes from Lagares das Beiras, between the south of the Douro River and the north of the Tagus River.
A town belonging to the Parroquia Oliveira do Hospital in Portugal.
In Lagares, olive plantations are plentify and the workers are known as lagareiros.
In the past, the mills were rustic tanks where olives were first crushed into paste. And, then large millstones would be used to crush the paste and extract the oil.
The process of making the oil was arduous and delicate and overseen by a lagareiro.
To make sure the oil was of the highest standard, some of the testing included using it in dishes.
In the town, bacalhau a lagareiro was made with the first harvest oil. When it turned out perfectly, it was a source of joy and relief knowing the olive oil was good.
The town’s oral tradition tells that, after a good harvest, there was a grand celebration with recipes.
The codfish was desalted, covered in breadcrumbs, and fried in olive oil directly in the Lagareiro.
Today we present the modern version of the bacalhau à lagareiro, baked with potatoes, onion, garlic and lots of olive oil.

Cooking The Potatoes
Bacalhau a Lagareiro, the classic Portuguese food is quite effortless to make.
The base of bacalhau a lagareiro, the classic Portuguese food is potatoes. Since potatoes have a longer cooking time than cod fillets, you have to cook everything separately.
It is best to bake or steam the potatoes until they about 70% done. These half-cooked potatoes are first lightly mashed and then baked a second time. This time with lots of fried onions and garlic, cod, and herbs.
Portuguese Olive Oil
Olive oil features prominently in Portuguese cuisine. It is added abundantly to numerous dishes including this bacalhau à lagareiro recipe.
You want to use high quality ingredients including Portuguese olive oil for the best flavors.
We’ve had the pleasure of using and cooking with Esporão’s olive oils, some of the best in Portugal from the Alentejo region.
The Esporão’s oils are produced using natural methods and traditional processes. What you get in the bottle are the best flavors preserved from the pure juice of the olives that are harvested.
For the best flavors for this simple recipe, consider using premium Portuguese olive oil.
Bake Cod and Potatoes
Slightly mash the baked potatoes and place the cooked onions over them. Spread the onions around to cover the potatoes.
Place the uncooked and seasoned pieces of cod loin on top of the punched potatoes. Drizzle with olive oil and put back in the oven. Bake for another 20 minutes at 300°F /150°C.
Bacalhau a Lagareiro Recipe
Ingredients
- 1 lbs cod fillets fresh or desalted
- 1.3 lbs potatoes small
- 3 cups white onion
- ½ cup Portuguese olive oil extra virgin
- 2 bay leaves
- 3 garlic cloves
- salt and pepper to taste
- ½ teaspoon hot paprika optional
- 2 tbsp cilantro or coriander chopped, optional
Instructions
- If you are using salted cod, start preparing the recipe two days in advance. Start by rinsing the cod with a little running water. Then, place it inside an airtight container, with a lid. Fill the container with enough water to cover the cod at least partially. Keep it inside the fridge. Every six hours, remove the cod from the fridge, drain the water, and top up again with more freshwater. This process removes the salt from the cod.
- If you are using ready to cook cod fish pieces, start by thawing them out if they are frozen.
- Select small potatoes of a similar size. Wash the potatoes thoroughly and make sure there is no traces of dirt. Then, using a sharp knife, scoop out the dark spots from the potatoes. Place the potatoes in the baking dish you’ll use to make the bacalhau a lagareiro recipe.
- Season the potatoes with salt and pepper. Bake them at t 300°F /150°C for approximately 20 minutes.
- While cooking the potatoes, peel and cut the onions into thin slices.
- Peel the garlic, and crush it.
- Pour the olive oil into a skillet over medium heat; When hot, add the sliced onions and the crushed garlic. Cook for about 10 minutes until onions are golden brown.
- Remove the half cooked potatoes from the oven. Mash lightly using a fork while being careful not to burn yourself. Mashing the potatoes ensures they are cooked evenly.
- Add the fried onion over the potatoes along with the bay leaves.
- Season the cod fillets with salt and pepper. Put them on top of the onions, drizzle a little olive oil over the cod, and put it in the oven at 150°C/300°F for another 15 to 20 minutes.
- Before serving, remove the bay leaves. If you wish, sprinkle a little paprika and chopped coriander on top.
