Introduction
Xiphias Souvlaki (Swordfish Souvlaki) is a premium coastal variation of the classic Greek skewer, replacing the usual pork or chicken with firm, meaty chunks of fresh swordfish. Unlike delicate white fish, swordfish maintains its integrity on the grill, allowing it to develop a charred, smoky exterior while remaining juicy and tender inside. The cubes are traditionally marinated in a bright mixture of extra virgin olive oil, lemon juice, and dried oregano, often skewered alongside bay leaves, bell peppers, and onions to infuse the meat with aromatic depth. It represents the height of Aegean summer dining, offering a lighter, sophisticated alternative to land-based street foods.
Ingredients
The Fish and Marinade
1 kg fresh swordfish steaks, cut into 4 cm cubes
1/2 cup extra virgin olive oil
1/4 cup fresh lemon juice
2 cloves garlic, minced
1 tbsp dried oregano
1 tsp salt
1/2 tsp freshly ground black pepper
The Skewer Additions
2 large green bell peppers, cut into chunks
2 medium red onions, cut into wedges
2 lemons, cut into thick slices or wedges
8 to 10 fresh bay leaves
The Dressing (Ladolemono)
1/4 cup extra virgin olive oil
2 tbsp fresh lemon juice
1 tsp dried oregano
A pinch of salt
Preperation
Fish: Trim any dark skin or bloodlines from the swordfish and cut into uniform 3 cm cubes.
Marinade: Whisk together the olive oil, lemon juice, dried oregano, and minced garlic in a non-reactive bowl.
Vegetables: Slice the bell peppers and red onions into square pieces that match the size of the fish cubes.
Skewers: Soak wooden skewers in water for at least 30 minutes to prevent them from burning on the grill.
Assembly: Thread the fish cubes onto the skewers, alternating with pieces of bay leaf, onion, and bell pepper.
Step by Step
The Fish: Cut fresh swordfish steaks into uniform cubes, roughly one inch in size. Ensure the skin and any dark "blood line" are removed to maintain a mild flavor and consistent texture.
The Marinade: Whisk together olive oil, lemon juice, minced garlic, dried oregano, and a touch of salt and pepper in a bowl. Toss the fish cubes in the mixture and let them marinate in the refrigerator for at least 30 minutes.
The Skewers: Thread the marinated fish onto skewers, alternating with pieces of bay leaf, thick slices of green bell pepper, and red onion wedges. The vegetables add moisture and aroma to the fish as it cooks.
The Grilling: Heat a grill or griddle pan to high heat. Cook the skewers for about 3 to 4 minutes per side, turning carefully, until the fish is opaque throughout and slightly charred on the edges.
Finishing: Drizzle the skewers with a fresh mixture of olive oil and lemon (ladolemono) immediately after removing them from the heat. Serve with warm pita bread or a side of rice pilaf.

Cultural History
Xiphias Souvlaki combines the ancient Greek technique of grilling meat on a skewer with the bountiful maritime heritage of the Aegean and Ionian seas. While meat-based souvlaki dates back to archaic antiquity, the adaptation of swordfish (xiphias) represents the coastal evolution of the dish, where firm, meaty steaks are treated with the same reverence as prime cuts of lamb. Often marinated in a classic latholemono (oil-lemon) dressing with wild oregano, the skewers are charred over open coals to highlight the fish's naturally rich flavor. Today, it stands as a staple of seaside tavernas, representing the transition of Greek cuisine from rustic mountain fare to a celebrated Mediterranean diet.
Yiayias Secret
The trick to succulent Xiphias (swordfish) is a short marinade; never leave the fish in lemon juice for more than thirty minutes or the acid will "cook" the protein and make it tough and rubbery. For the best texture, soak the wooden skewers in water first and thread a fresh bay leaf and a piece of green bell pepper between every cube of fish. The bay leaf infuses the meat with a subtle woodsy aroma as it hits the grill. Finally, always brush the skewers with a Ladolemono (lemon-olive oil) mixture immediately after they leave the heat to lock in the natural moisture.
Substitution Notes
The Fish: If Swordfish is unavailable, other firm-fleshed fish like Halibut, Mahi-Mahi, or Fresh Tuna make excellent substitutes. These varieties hold their shape well on a skewer and won't flake apart over high heat.
The Marinade: If you find fresh lemons too tart, you can use preserved lemon or a splash of white balsamic vinegar. For a deeper herbal profile, replace the dried oregano with fresh thyme or rosemary.
The Vegetables: While bay leaves, onions, and bell peppers are traditional on the skewer, you can substitute with zucchini rounds or cherry tomatoes. The acidity of the tomatoes complements the meaty texture of the fish perfectly.
The Oil: Extra virgin olive oil provides the best flavor for the Mediterranean profile, but if you prefer a higher smoke point for grilling, a neutral avocado oil can be used for the initial sear.
Serving: For a low-carb alternative to pita bread, serve the skewers over a bed of cauliflower rice or a crisp shredded cabbage salad dressed with lemon and oil.
Wine Pairings
Xiphias Souvlaki features meaty, charred swordfish cubes marinated in lemon, olive oil, and herbs, creating a balance between smoky grill marks and clean oceanic flavors.
White Wine (The Traditional Choice): A dry, mineral-driven white is ideal for the dense texture of swordfish. A Santorini Assyrtiko provides a salty acidity that mimics the sea, while a Vermentino or a Pinot Grigio offers a bright citrus profile that elevates the lemon marinade.
Red Wine: For a red pairing, look for something light and translucent with high acidity. A Cretan Kotsifali or a Schiava provides delicate red berry notes that complement the smoky char of the grill without masking the flavor of the fish.
The Contrast: A dry Rosé from Provence or a Pale Agiorgitiko offers a floral and strawberry bouquet that softens the meaty texture of the swordfish while standing up to the garlic and oregano.
Storage Instructions
Refrigeration: Once the swordfish skewers have cooled to room temperature, place them in an airtight container. They will stay fresh in the refrigerator for up to 2 days. For the best texture, consume them as soon as possible, as seafood can become tough when stored.
Freezing (Cooked): Freezing cooked swordfish is not recommended, as the delicate texture of the fish becomes dry and rubbery once thawed and reheated.
Freezing (Unbaked): You can freeze the raw swordfish cubes in a freezer safe bag for up to 2 months. For the best results, do not freeze them in the lemon based marinade, as the acid will "cook" the fish and change its consistency. Marinate them fresh after thawing.
Reheating: To avoid overcooking the fish, reheat the skewers in the oven at 150°C covered tightly with foil for about 10 minutes or until just warmed through. Avoid the microwave, as it will likely make the swordfish very dry.
