Portuguese-style baked sardines drizzled with olive oil, garlic, and a bright finish of fresh mint.
Sardines are practically a national symbol in Portugal, grilled over open coals at every summer festival, especially during the Santos Populares celebrations in June. This baked version brings the same beloved fish into the oven with a simpler, more everyday approach, finished with fresh mint and good olive oil for brightness against the fish's natural richness. The technique for baked sardines is minimal by design -- the fish needs little more than salt, olive oil, and high heat to cook through in under 15 minutes, with the skin crisping slightly under the oven's heat. Adding sliced garlic underneath the fish as it roasts infuses the olive oil with flavor, which then gets spooned back over the sardines along with fresh mint just before serving, a herb that's less common than parsley in Portuguese fish cookery but adds a cooling brightness. Served simply with boiled potatoes and a green salad, this dish celebrates Portugal's deep coastal food culture, where the quality of the fish and olive oil matters far more than a complicated preparation.
Serves 5
Preheat oven to 220°C (425°F).
Scatter sliced garlic in the bottom of a baking dish and drizzle with half the olive oil.
Pat sardines dry, season with salt and pepper, and arrange on top of the garlic in the dish.
Drizzle remaining olive oil over the sardines. Bake 10-12 minutes until the fish is just cooked through and the skin is lightly crisped.
Spoon the garlicky pan juices back over the sardines and scatter with fresh mint.
Serve immediately with lemon wedges and boiled potatoes.
Use the freshest sardines you can find -- their flavor and texture degrade quickly, so this dish depends heavily on quality.
Don't overbake; sardines cook fast and turn dry within a couple minutes of being done.
Spoon the pan juices back over the fish before serving so none of that garlicky olive oil flavor is wasted.
Grill the sardines over charcoal instead of baking for the traditional summer festival preparation.
Use parsley instead of mint for a more classically Portuguese herb pairing.
Add a splash of white wine to the baking dish for extra depth.
Best eaten immediately while fresh. Sardines don't keep or reheat well; leftovers are best eaten cold within a day.
Sardines hold deep cultural significance in Portugal, especially during the June Santos Populares festivals in Lisbon, where grilled sardines are eaten in massive quantities as a symbol of Portuguese summer tradition.
Yes, thaw completely and pat very dry before baking, since fresh sardines are seasonal and not always available.
Fresh parsley is the more traditional Portuguese herb choice and works well as a substitute.
Many fishmongers will scale and gut them for you on request, which saves considerable prep time.
