Sardinhas Assadas is whole fresh sardines salted heavily and grilled hard over live coals until the skin blisters and chars, served simply with boiled potatoes and a roasted pepper salad. You make it by salting the fish well ahead of grilling, cooking them fast over very high heat, and serving them whole, bones and all, with nothing more than bread, potatoes, and good olive oil alongside.
Grilled sardines are inseparable from Portuguese summer, especially the Festas dos Santos Populares in June, when the smell of sardines grilling on charcoal fills the streets of Lisbon and Porto. The dish is defined by its simplicity: fresh, whole, small fish cooked hot and fast, nothing more.
Sardines are an oily fish that can go from perfectly charred to dry and overcooked in a matter of a minute or two, so the whole dish depends on getting the heat and the timing right.
What Actually Matters
Salt the sardines generously with coarse salt at least 30 minutes before grilling, and grill them over the hottest part of the coals or grill you have, turning once, for only a few minutes per side. Sardines are small and oily, so they cook fast, and overcooking them past the point of just cooked through dries out what should be a rich, juicy fish. Resist moving them around on the grill, let the skin blister and release naturally before flipping.
Sardinhas Assadas Recipe
Serves 4. Prep time: 15 minutes (plus 30 minutes salting). Cook time: 10 minutes. Total time: 25 minutes, not counting salting.
Ingredients
- 16 whole fresh sardines, gutted and scaled
- 2 tablespoons coarse sea salt
- 1.5 pounds small potatoes, boiled and halved
- 2 red bell peppers, roasted, peeled, and sliced
- 1/4 cup olive oil, plus more for drizzling
- 2 tablespoons red wine vinegar
- 1 clove garlic, minced
- Crusty bread, for serving
Method
- Pat the sardines dry and salt them generously on both sides with the coarse salt. Let them sit for at least 30 minutes at room temperature.
- Preheat a grill or grill pan to the highest heat setting.
- Toss the roasted pepper slices with the olive oil, red wine vinegar, garlic, and a pinch of salt to make a simple salad. Set aside.
- Rinse the excess salt off the sardines if it seems heavy, then pat dry again.
- Grill the sardines over direct high heat for 3 to 4 minutes per side, without moving them, until the skin is blistered and charred and the flesh is opaque throughout.
- Arrange the sardines on a platter with the boiled potatoes and pepper salad alongside.
- Drizzle everything with extra olive oil and serve immediately with crusty bread.

Tips, Variations, and Storage
Buy the freshest sardines you can find, ideally the same day you plan to grill them, since fish this small and oily degrades quickly. A charcoal grill gives the most authentic smoky flavor, but a hot grill pan or broiler works as a substitute if you don't have outdoor access. These are best eaten immediately, hot off the grill, and don't reheat well since the skin loses its char.
Frequently Asked Questions
Do I need to remove the bones before eating?
No, traditionally the fish is served whole and eaten off the bone at the table, similar to a whole grilled trout.
Can I use frozen sardines?
Fresh is strongly preferred for both texture and flavor. Frozen sardines can work in a pinch but will be softer and slightly less flavorful.
Why do you salt the sardines ahead of time?
The rest period lets the salt season the fish through to the flesh, not just the surface, and helps firm up the texture slightly before grilling.
What if I don't have an outdoor grill?
A cast iron grill pan heated very hot on the stovetop, or a broiler, both work well as substitutes and still develop good char.
What other sides go well with this?
Besides potatoes and roasted peppers, a simple green salad or grilled corn are both common, casual accompaniments.
