In this article
Meet Bacalhau à Gomes de Sá, one of Portugal’s most cherished dishes and a true icon of the country’s seafaring kitchen. This rustic casserole layers flakes of salt cod with sliced potatoes, sweet golden onions and plenty of fruity olive oil, all finished with hard-boiled egg, glossy olives and a scattering of parsley. Often reserved for special occasions, it is just as welcome at a relaxed family supper — a warming, generous plate that brings a little of Porto straight to your table.
About Bacalhau à Gomes de Sá
Bacalhau à Gomes de Sá is a traditional Portuguese dish that reflects the culture and eating habits of Portugal like few others. It is a baked casserole built around salt cod — dried and salted cod prepared in the style created by Gomes de Sá. The recipe is not only simple to put together but also wins hearts with its layered, savoury flavours and its devotion to good regional ingredients. It is frequently served at festive gatherings, yet it works equally well as a cosy dinner at home.
Ingredients (serves 1–2)
- 300 g bacalhau (salt cod)
- 2 large onions
- 2 cloves of garlic
- 3 medium potatoes
- 2 eggs
- ½ cup olive oil
- 1 cup milk
- Olives and parsley, to garnish
- Salt and pepper, to taste
Shopping for the ingredients
To make the best Bacalhau à Gomes de Sá, choose ingredients that are fresh and of good quality. Visit a local fishmonger or a delicatessen for the salt cod, as the quality of the fish often makes all the difference here. Look for natural, untreated products so you capture the true flavour of the dish. The spices and fresh vegetables you need are easy to find in a well-stocked supermarket or at a weekly market, much as you would when gathering everything for a Caldeirada de Peixe.
Preparing the dish
Before you start cooking, it is important to prepare the salt cod properly. It should be soaked in plenty of cold water to draw out the excess salt. This can take several hours, so it is well worth doing the evening before. The other ingredients — the onions and potatoes in particular — should be washed and prepared thoroughly to give the dish a flavoursome, well-organised base.
Step-by-step instructions
- Soak the salt cod in water, then drain it well and break it into pieces.
- Peel the potatoes, slice them, and boil in lightly salted water until just tender.
- Fry the onions and garlic in olive oil until golden brown.
- Layer the cod and potatoes in a baking dish and spoon the onion mixture over the top.
- Hard-boil the eggs, peel them and cut into slices.
- Pour the milk over the casserole, season with salt and pepper, and arrange the egg slices on top.
- Bake in a preheated oven at 180°C for about 20–25 minutes.
- Garnish with olives and fresh parsley, then serve.
Gluten-free / lactose-free version
Bacalhau à Gomes de Sá is easily made gluten-free, since the potatoes act as the main starch and you can simply use a gluten-free milk alternative. For a lactose-free version, swap the dairy for a plant-based milk alternative such as almond or oat milk. These adjustments mean people with dietary restrictions can still enjoy the dish without losing any of its hearty character. Just take care to check ingredient labels for any unexpected additives so the meal stays fully gluten- and lactose-free.
Tips for vegans and vegetarians
For a vegan take, Bacalhau à Gomes de Sá adapts beautifully if you replace the fish with marinated tofu or a mix of vegetables. These alternatives bring their own dimension of flavour that sits happily alongside the dish’s traditional aromas. Instead of milk, reach for a plant-based milk substitute to keep everything lovely and creamy. A pinch of smoked paprika also helps create that savoury, umami depth the dish is known for.
More tips and tricks
Getting the salt cod right is key to the finished result. Be careful not to soak it for too long, or it can lose its character and taste flat. Experimenting with herbs and spices can lift the casserole further. A great trick is to finish it with a squeeze of lemon juice or a drizzle of good olive oil just before serving, intensifying the aromas and adding a refreshing note to every bite.
Adapting the recipe to your taste
The great strength of Bacalhau à Gomes de Sá is its versatility. You can vary the ingredients to suit yourself — perhaps adding vegetables such as broccoli or carrots, or stirring in extra spices. These tweaks help you make the dish more personal or simply better matched to your palate. If you need to leave out certain ingredients, sides such as quinoa or rice make excellent additions to round out the meal.
Ingredient substitutions
If onions are not to your taste, you can swap them for spring onions or shallots for a milder flavour. The potatoes can occasionally be replaced with parsnips or homemade mash for a fresh twist. For the creamy consistency, further milk alternatives such as soya or coconut milk also work well. Substitutions like these keep the recipe varied and interesting — much like the playful approach you might take with Pataniscas de Bacalhau.
Drink pairing ideas
With Bacalhau à Gomes de Sá, I would suggest a glass of Portuguese Vinho Verde, which harmonises beautifully with the flavours of the dish. A cool, light beer or a fruity rosé also pairs nicely. For alcohol-free options, unsweetened iced tea or a fresh citrus mocktail rounds things off perfectly. It is well worth experimenting with different combinations to find your ideal match.
Serving and presentation ideas
Presentation makes all the difference to how appealing the dish looks. Serve Bacalhau à Gomes de Sá in an attractive, well-greased baking dish and garnish it with fresh parsley and olives. Plating it on a large platter surrounded by a leafy salad is another lovely way to show it off. Serve the casserole hot, and perhaps add a slice of lemon for an extra lift of flavour.
A bit of history
Bacalhau à Gomes de Sá has its origins in the city of Porto and was created by a well-known fish merchant named José Gomes de Sá. The dish reflects the long tradition of Portuguese cuisine, which is shaped so strongly by seafaring and by the practice of preserving fish through salting. The love of bacalhau, kept alive across the centuries, makes this casserole an unmistakable part of Portugal’s food culture. It is often said that every Portuguese cook prepares bacalhau at least once a year for their festive meals.
