How to Grill Sardines: A Healthy Seafood BBQ for Summer
Grilled Sardines: A Cultural Staple in Portugal
Grilled sardines (sardinhas assadas) have deep roots in Portuguese culinary tradition, especially along the Atlantic coast where fresh fish is a way of life. They became particularly iconic in Lisbon’s annual June festivals, where locals set up makeshift grills on narrow cobbled streets and serve sardines atop slices of rustic bread or with boiled potatoes and salad.
The tradition reflects Portugal’s strong fishing heritage and love for communal outdoor dining. These festivals bring together neighbors and visitors alike, with the grilled sardine at the heart of it all. Typically sardines are gilled simply with sea salt, but I think paprika and olive oil are great additions that rounds out the smokiness of this dish. Finished with a spritz of lemon and you have a refreshing, healthy and bright meal to enjoy.
Why Sardines Are a Healthy Choice
Sardines are often called a superfish, and for good reason. They’re:
- Packed with Omega-3s: These heart-healthy fats help reduce inflammation and improve cardiovascular health.
- High in Protein: Sardines are an excellent source of lean protein to support muscle health.
- Rich in Calcium and Vitamin D: Especially when eaten whole with bones, sardines offer significant amounts of bone-building nutrients.
- Low in Mercury: Unlike larger fish, sardines are low on the food chain and accumulate less mercury, making them a safer choice for regular consumption.
In short, sardines are one of the most nutrient-dense and sustainable seafood options out there.
How to Prepare Sardines for Grilling
There are a few common ways to prep sardines before grilling:
- Whole and Ungutted: Traditional Portuguese street vendors often grill sardines whole, guts and all, especially when extremely fresh. It keeps the fish moist and flavorful.
- Gutted and Scaled: For home cooking, many prefer to clean the sardines first. Gently remove the innards and rinse under cold water. Some people scale them; others leave the skin on for texture and taste.
- Butterflied: Less traditional but useful for marinades, the sardines can be butterflied and deboned for easier eating.
Freshness is key—look for sardines with clear eyes, firm flesh, and a clean ocean scent.
What to Serve with Grilled Sardines
Pair your sardines on the side, keep it rustic and light:
- Sliced heirloom tomatoes with olive oil and oregano
- Grilled Fingerling Potatoes
- Boiled new potatoes with a drizzle of olive oil
- Grilled bell peppers or corn
- A chilled bean salad or bread to soak up the juices
What to Serve with Grilled Sardines
Grilled sardines have bold, briny flavors and a smoky finish from the grill, which pair best with crisp, acidic white wines that can cut through the oiliness of the fish and enhance the seasoning.
Best Wine Pairings:
- Vinho Verde (Portugal)
Light, slightly effervescent, and citrusy—this classic Portuguese wine is the perfect match for sardines. Its freshness balances the richness of the fish and the lemon accent. - Albariño (Spain)
From across the border, this Spanish white is mineral-driven with notes of stone fruit and citrus. It’s ideal for grilled seafood and stands up well to paprika. - Arinto (Portugal)
A structured, high-acid white wine from regions like Bucelas or the Lisbon area. Arinto’s lemony, mineral profile complements grilled sardines perfectly. - Vermentino (Italy or Corsica)
Herbaceous, crisp, and with a saline touch—Vermentino pairs beautifully with Mediterranean fish dishes like this. - Dry Riesling (Germany or Alsace)
For those who enjoy something a bit more aromatic, a dry Riesling offers bright acidity and citrus notes that highlight the paprika and lemon in the dish. - Sparkling Wine
A dry sparkling wine like Portuguese Espumante or a crisp Cava also works well, refreshing the palate between bites.
Red Wine Option:
If you prefer red, opt for a light, chilled red such as:
- Vinhão (Portugal)
A bold, deep-colored wine often served lightly chilled in the north of Portugal. Tart and rustic, it stands up surprisingly well to grilled sardines. - Pinot Noir (cool climate)
A young, fresh Pinot Noir served slightly chilled can work in a pinch, especially if served with grilled vegetables or tomato-based sides.

How to Grill Sardines (Sardinhas Assadas)
Ingredients
- 6 fresh sardines
- 2-3 pinches sea salt or kosher salt, diamond crystal or sea salt
- 1-2 pinches white pepper, or grind fresh white pepper for light layer on the sardines
- 1 tsp sweet paprika
- 2 tbsp good-quality olive oil
- lemon wedges, for serving
Equipment
- grill charcoal or gas
- medium bowl
- tongs
- fish grill grate optional
Instructions
- Rinse and pat the sardines dry. Remove any loose scales.
- If you prefer, clean and gut the sardines more thoroughly. This is optional, and typically sardines are grilled without much preparation.
- In a medium bowl, place the sardines inside. Season with the salt, white pepper, and paprika. Drizzle olive oil on top and then rub the sardines to spread the seasoning and oil evenly over both sides.
Preheat a charcoal or gas grill to medium-high. Place the sardines directly on the grill grate or use a fish grill basket. Grill for 3 minutes on the first side, then flip and grill for 2-3 minutes on the other side. The skin should be blistered and the fish will be cooked through but still moist. Trust that it will be a quick cooking time over high heat as overcooking can make the sardines mushy or dry.
Remove the sardines from the grill and finish with a generous spritz of fresh lemon. Serve immediately with crusty bread, boiled potatoes, grilled vegetables, or a tomato-onion salad.
