Step into the rich culinary traditions of Portugal with Bacalhau à Gomes de Sá, a revered classic that brings together succulent salt cod, tender potatoes, and caramelized onions in a deeply satisfying casserole. This particular rendition stays true to the authentic spirit of the dish, embracing all its traditional flavors and hearty essence. However, it introduces one ingenious adaptation: instead of the laborious process of peeling, boiling, and then slicing potatoes, we opt for very thinly sliced raw potatoes, layered directly into the baking dish and cooked entirely in the oven. This simple yet effective tweak not only saves significant preparation time but also yields a delightful texture, ensuring a perfect weeknight meal or a celebratory feast.
The Enduring Legacy of Bacalhau: A Culinary Journey
For many, Bacalhau à Gomes de Sá isn’t just a meal; it’s a connection to heritage, a taste of home, and a centerpiece of Portuguese gatherings. My own journey with bacalhau began with a child’s typical reluctance, often pushing away anything explicitly Portuguese from my plate. Yet, I vividly recall watching my father, with an unwavering love, devour countless servings of this very dish, a testament to its profound appeal. It wasn’t until I reached adulthood that I truly began to appreciate the comforting embrace and profound flavors of this classic casserole.
Salt cod, or “bacalhau,” holds an almost sacred status in Portuguese gastronomy. Legend has it that there are 365 ways to prepare bacalhau, one for each day of the year, though many would argue there are even more! This versatile ingredient, traditionally dried and salted, requires careful reconstitution through soaking before it transforms into the flaky, flavorful fish that defines so many beloved Portuguese dishes. Bacalhau à Gomes de Sá stands out as one of the most celebrated preparations, named after its creator, José Luiz Gomes de Sá Júnior, from Porto, Portugal.
The traditional method for preparing the potatoes in this dish involves a multi-step process: peeling, boiling until tender, cooling, and then slicing them into quarter-inch thick rounds. While this yields a specific texture, I discovered a significant time-saving shortcut that doesn’t compromise on flavor or authenticity. By slicing the potatoes even more thinly—aiming for 1/16 to 1/8 inch thickness—and layering them raw in the casserole to cook directly in the oven, you can shave off nearly an hour of prep time. This not only streamlines the cooking process but also allows the potatoes to gently absorb the rich flavors of the olive oil, onions, and cod as they bake, resulting in a wonderfully integrated dish.

- 6 large hard-boiled eggs: 4 eggs sliced crosswise into 5 or 6 pieces each; the remaining 2 eggs cut lengthwise into quarters for garnish
- 2 tablespoons chopped fresh flat-leaf parsley, for garnish
Instructions
- Preheat Oven: Position an oven rack in the middle of your oven and preheat to 350°F (176°C).
- Sauté Onions: Drizzle a generous amount of olive oil (about 3 to 4 tablespoons) into a large skillet and heat over medium-high heat until shimmering. Add the sliced Spanish onions and bay leaves. Cover the skillet and cook, stirring occasionally, for 20 to 25 minutes, or until the onions are beautifully golden and soft. Stir in the minced garlic and cook for another minute. Remove from heat and allow to cool slightly.
- Prepare Casserole Dish: Liberally coat a 2-quart casserole dish with olive oil. Sprinkle the bottom lightly with salt and freshly ground black pepper.
- Layer Potatoes: Arrange a layer of thinly sliced potatoes at the bottom of the prepared casserole dish, overlapping them slightly to create an attractive concentric, flower-like pattern.
- Add Onions and Olives: Scatter a portion of the cooked onions and some sliced olives evenly over the potato layer.
- Incorporate Salt Cod: Place chunks of the cooked and flaked salt cod over the onion and olive layer.
- Egg Layer: Top with slices from one of the hard-boiled eggs.
- Repeat and Season: Cover this layer with another portion of thinly sliced potatoes. Drizzle with a good glug of olive oil and season generously with salt and pepper. Continue this layering process—onions and olives, salt cod, sliced egg, and then potatoes, salt, and pepper—until all ingredients are used, ensuring the final layer is potatoes. Gently press down on the casserole occasionally to ensure the layers are compact and even.
- Bake Covered: Cover the casserole dish tightly with aluminum foil and carefully transfer it to the preheated oven. Bake for 30 to 60 minutes, or until the potatoes are tender when pierced with a fork or skewer. The exact time will depend on the number and thickness of your layers.
- Brown the Top: Remove the foil and continue baking for approximately 10 minutes more, or until the top layer of potatoes is lightly golden brown.
- Rest and Garnish: Carefully remove the casserole from the oven and let it cool slightly before serving. Garnish generously with the remaining sliced olives, the chopped fresh parsley, and the quartered hard-boiled eggs. Proudly carry this magnificent pot to your table and wish everyone “bom appetite!”
Tips for a Perfect Bacalhau à Gomes de Sá
- Quality Salt Cod: The success of this dish hinges on good quality salt cod. Purchase it from a reputable source and follow proper rehydration techniques to ensure it’s perfectly desalted and tender.
- Mandoline for Potatoes: A mandoline slicer is highly recommended for achieving uniformly thin potato slices, which ensures even cooking and a beautiful presentation. If you don’t have one, take your time with a sharp knife.
- Don’t Skimp on Olive Oil: Olive oil is a cornerstone of Portuguese cuisine. Use good quality extra virgin olive oil generously throughout the dish, as it contributes significantly to the flavor and texture.
- Seasoning is Key: Taste and adjust seasoning at each stage. Salt cod can still be quite salty even after soaking, so be mindful when adding extra salt, especially to the potatoes.
- Resting Time: Allowing the casserole to rest for a few minutes after baking helps the flavors meld and the layers set, making it easier to serve.
- Make Ahead: This casserole can be assembled a day in advance and refrigerated. Bring it to room temperature before baking, and you might need to add a few extra minutes to the baking time.

Insights from Our Recipe Testers
We believe the best recipes are those put to the test in real kitchens. Here’s what our dedicated recipe testers had to say about making and enjoying this Bacalhau à Gomes de Sá:
Ilda Costa-Sarnicki
For Ilda Costa-Sarnicki, Bacalhau à Gomes de Sá is a cherished dish, gracing her table at least twice a year and a guaranteed feature during her annual visits to the Azores. While deeply familiar with the flavors, this particular recipe presented an intriguing twist: a truly one-dish preparation, a departure from the usual method of cooking components separately and then assembling. She particularly appreciated the use of pitted and sliced olives, noting that the small Galega olives can sometimes present an unwelcome surprise with their pits. Her concern about the golden potato slices being tinted proved unfounded, but she did observe that the Yukon Gold potatoes retained a slight “bite” even after 60 minutes of baking, desiring a creamier texture. She also expressed a preference for parsley distributed throughout the layers, rather than just as a top garnish.
Ilda also shared valuable insights regarding the hard-boiled eggs. While the unbaked top layer of eggs was perfect, the slices incorporated into the baked layers became slightly rubbery. This led her to a thoughtful suggestion for future attempts: using 5-minute eggs, coarsely mashed and layered with parsley, reserving fully cooked egg slices for the final garnish. Despite the potatoes retaining a firm texture, she wouldn’t swap them out, appreciating how their thin slices held their shape. Her solution? An additional 10 minutes of baking time for her next batch. She found the potato to cod and onion ratios ideal, and the quantities perfectly suited her 2-quart cast-iron Dutch oven, suspecting her 6 layers of potatoes contributed to the longer cook time. Ilda enthusiastically concluded that she wouldn’t sacrifice the stunning presentation of this tall, layered cod casserole for a shallow pan, eager to share her tweaked version with family, certain the familiar flavors combined with the unexpected thin potato wafers would impress!
Our Second Tester’s Experience
This tester shared a profound, lifelong love for bacalhau, noting its significant role in both joyful celebrations and somber occasions from their childhood. With a Portuguese husband, their appreciation for the “1001 ways to make bacalhau” deepened. Having prepared bacalhau many times, they were particularly excited to try this casserole version, which was entirely new to them. The process, though lengthy, was described as “fun and long,” with every minute thoroughly enjoyed.
Their preparation began with the crucial step of reconstituting the salt cod. Opting for a 36-hour soak, they aimed for a slightly salty, rather than completely bland, flavor profile – a personal preference refined over years of cooking. Once the cod was ready, it took about 50 minutes to cook, cool, and clean. During this time, eggs were hard-boiled using a precise method: starting in cold water, bringing to a boil, then shutting off the heat and letting them sit covered for exactly 10 minutes, resulting in consistently perfect eggs.
Proudly using an authentic Portuguese casserole dish, they presented the dish to the table after a short resting period. While parsley was added as instructed, they chose to serve the eggs and olives on each individual plate, finishing with an extra drizzle of olive oil. The first bite was a revelation: “Salt, creamy potatoes, eggs, it was incredible.” The potatoes were perfectly tender, and the seasoning was spot on, creating a cohesive and flavorful experience. The casserole was far from dry, a testament to the recipe’s balance. Paired with a pleasant, not-too-sweet rosé, the meal was thoroughly enjoyed by both the tester and their husband, who eagerly anticipated the leftovers, admiring the “beautiful flower pattern of potatoes and goodness.”
Heidi V.
Heidi V. initially approached this Bacalhau à Gomes de Sá recipe with a healthy dose of skepticism, which, she admits, was precisely why she decided to try it. Residing in the Caribbean, where salt fish is a Jamaican staple and readily available due to a significant Jamaican population, she had never actually incorporated it into her own home cooking. Her curiosity was piqued, and she couldn’t be happier with the outcome, a sentiment enthusiastically echoed by her partner.
She described the dish as a “super satisfying, perfectly balanced, one-dish meal” that was not only easy to prepare but also yielded excellent leftovers. While acknowledging that the salt fish preparation (reconstitution) takes time, she emphasized that it involves very little active prep, making the overall effort “totally worth it.” Heidi felt confident enough in the dish’s appeal to prepare and bring it to a dinner party, noting its deceptively simple, even humble, appearance. However, she asserts that “with the first bite the flavor completely sweeps you off your feet.”
Heidi managed to create four distinct layers of potatoes, meticulously sliced to 1/8 inch thick using her mandoline. She considered trying slightly thinner slices next time but found that her current thickness layered perfectly into her dish, with just enough potatoes to complete the construction. Her initial doubts, fueled by the considerable start-to-finish time, would have made a poor result disheartening. Yet, she reaffirmed her trust in the recipe source, declaring this Bacalhau à Gomes de Sá “a win in my book.”
Serving Suggestions and Wine Pairings
Bacalhau à Gomes de Sá is a robust and flavorful dish that stands beautifully on its own. However, to complete a truly Portuguese dining experience, consider pairing it with a simple, fresh garden salad dressed with a light red wine vinaigrette. The acidity and freshness of the salad cut through the richness of the casserole, creating a delightful balance. For a truly authentic touch, a crisp Portuguese green wine (Vinho Verde) would be an excellent choice, offering bright acidity and minerality that complements the saltiness of the cod. If you prefer red wines, a medium-bodied Portuguese red from the Douro or Dão region, with its notes of dark fruit and earthy undertones, would also pair wonderfully. Our tester Ilda even suggested a Valpolicella Ripassa, demonstrating that a well-chosen Italian red can also find its place alongside this Portuguese gem.
