Best Time to Eat and How to Partner

Patatas Alioli is typically served cold or at room temperature, making it perfect for hot summer evenings, aperitivo hour, or as part of a tapas spread. It’s a go-to dish at informal gatherings, picnics, or laid-back dinners with friends where sharing is the name of the game.

For the ultimate pairing, serve it alongside other classic tapas like Spanish tortilla, pan con tomate, olives, or jamón ibérico. Want to keep it vegetarian? Pair it with grilled vegetables or marinated mushrooms. And for drinks, nothing goes better than a chilled glass of cava, a dry sherry, or even a light vermouth on ice—very Spanish, very satisfying.

Pro tip: make the dish a few hours in advance and let it rest in the fridge. This allows the garlic and olive oil to fully infuse the potatoes for deeper flavor.

Despite its simplicity, Patatas Alioli sparks strong opinions—especially among Spaniards. One of the biggest controversies? The use of mayonnaise. In many modern versions, cooks shortcut the aioli by mixing garlic with jarred mayo. While it’s convenient, purists argue it’s an insult to tradition, which calls for homemade alioli emulsified from just garlic, olive oil, and salt.

Another point of debate is the amount of garlic. True alioli isn’t just flavored with garlic—it’s dominated by it. Yet many restaurant versions tone it down to appeal to broader palates, making the dish milder but, some argue, forgettable. In regions like Catalonia and Valencia, garlic lovers expect a bold punch.

And then there’s the texture. Authentic Patatas Alioli shouldn’t be mashed or creamy like potato salad. The potatoes must hold their shape—firm but tender—and the alioli should cling to them rather than soak in. Over-mixing or serving it warm? That’s where many tourists (and even some chefs) get it wrong.

Step By Step How to Make Patatas Alioli

Prepare the Potatoes

Wash the potatoes thoroughly. If they are large, cut them into bite-sized pieces. If they are small, you can leave them whole or halve them.

Place the potatoes in a large pot and cover them with cold water. Add a generous pinch of salt to the water. Bring the water to a boil and cook the potatoes until they are tender but not falling apart, about 15-20 minutes. Drain the potatoes and let them cool slightly.

Make the Alioli

In a mixing bowl, combine the egg yolk, minced garlic, and lemon juice (or vinegar). Slowly start to whisk in the olive oil drop by drop until the mixture begins to thicken. Once it starts to thicken, you can add the oil in a slow, steady stream, alternating between the olive oil and sunflower oil. Continue whisking until you have a thick, creamy mayonnaise.

Add salt to taste and a pinch of black pepper if desired. Adjust the garlic and lemon juice to your taste.

Assemble the Dish

Once the potatoes have cooled slightly, toss them in the alioli until they are well coated. You can serve the dish warm or at room temperature. Garnish with chopped fresh parsley for a touch of color and freshness (optional).

Serve the Patatas Alioli as a tapa or side dish.

Tips To Make Patatas Alioli

If your alioli is too thick, you can thin it out with a teaspoon of water or lemon juice. If it’s too thin, add more oil while whisking. If you prefer, you can use a blender or immersion blender to make the alioli, following the same method but blending instead of whisking.

Adjust the amount of garlic to your taste. For a milder flavor, you can roast the garlic before adding it to the mayonnaise.

If you’re short on time, you can mix minced garlic and lemon juice into store-bought mayonnaise to create a quick version of alioli.

Serving Suggestions

The beauty of traditional Spanish tapas lies in how effortlessly they can fit into different dining situations. This particular dish, often misunderstood by tourists, is best served in its most authentic form: freshly prepared, warm, and shared among friends with a glass of Spanish wine or vermouth. Keeping it simple allows the flavors to shine without unnecessary additions.

For a more casual setting, pair the dish with crusty bread or toasted baguette slices. This makes it easy to scoop up every last bit while adding texture and substance to the meal. A drizzle of quality olive oil or a sprinkle of smoked paprika can elevate the presentation while still staying true to its roots.

If you want to create a complete tapas spread, serve it alongside complementary small plates such as patatas bravas, marinated olives, or grilled vegetables. This creates a balance of flavors and textures and highlights the social nature of Spanish dining, where conversation and food flow together seamlessly.
