Step-by-Step Instructions

Step 1: Make the onion and parsley salad

Start by preparing the bright, tangy onion salad so it has a few minutes to soften. Place the thinly sliced red onion in a medium bowl. Sprinkle with the salt and sumac (if using), then drizzle in the lemon juice and olive oil. Use your fingers to gently massage the seasonings into the onion for about 30 seconds; this helps take away the sharp raw bite and makes the onion more tender. Add the chopped parsley and toss everything together until well combined. Taste and adjust with a pinch more salt or lemon if needed. Set the bowl aside at room temperature while you prepare the fish. The flavors will meld and the onion will relax beautifully.

Step 2: Mix the marinade for the fish

In a separate large bowl or shallow dish, whisk together 2 tablespoons olive oil, 2 tablespoons lemon juice, minced garlic, ground cumin, paprika, salt, and black pepper until you have a smooth, fragrant marinade. Pat the fish fillets dry with paper towels so the marinade can cling better. Add the fish to the bowl, turning each fillet gently to coat all sides in the seasoning. Let the fish marinate for 10 minutes at room temperature while you preheat your grill or grill pan. This short rest infuses the fish with flavor without making it mushy.

Step 3: Preheat your grill or grill pan

Heat a grill pan on the stovetop or an outdoor grill to medium-high heat. You want it hot enough to get light char marks without burning the delicate fish. Lightly oil the grill grates or grill pan with a thin film of neutral oil or a bit of olive oil (use a folded paper towel and tongs for safety). If you do not have a grill, you can use a heavy nonstick or cast-iron skillet instead; preheat it over medium-high heat in the same way. While the pan heats, slice your bread: if using long baguettes, cut each in half to make 4 sandwich portions, then split each piece lengthwise, keeping one long side attached like a book.

Step 4: Grill the fish fillets

Once the grill or pan is hot, place the marinated fish fillets on it, skin side would go down first if there was skin, but here just place the smoother side down. Let them cook undisturbed for 3–4 minutes, until the underside has light golden char marks and the fish is turning opaque around the edges. Carefully flip each fillet with a thin spatula and cook for another 2–3 minutes, depending on thickness, until the fish is opaque all the way through and flakes easily with a fork. Avoid overcooking so the fish stays juicy. Transfer the cooked fillets to a clean plate and immediately squeeze a little fresh lemon juice over them. Keep warm while you toast the bread.

Step 5: Toast the bread and prepare the fillings

Place the split bread, cut side down, directly on the grill or in the hot pan. Toast for about 1–2 minutes until the surface is lightly crisped and warmed, but the bread is still soft inside. Remove and arrange the bread on a work surface. Line the bottom of each sandwich with a generous handful of shredded lettuce for freshness and crunch. Give the onion and parsley salad a quick toss, then taste and adjust seasoning if necessary. Have your lemon wedges and remaining tablespoon of olive oil ready for assembly so you can build and serve the sandwiches while the fish is still hot.

Step 6: Assemble your balık ekmek sandwiches

To assemble, place one hot grilled fish fillet on top of the lettuce in each sandwich. Spoon a generous amount of the onion and parsley salad over the fish, making sure some of the tangy juices soak into the bread. Drizzle a little olive oil over the filling, then add a final pinch of salt and black pepper if you like. Squeeze a lemon wedge over each sandwich just before closing the bread around the filling. Serve immediately, ideally with extra lemon wedges, more sumac or chili flakes for sprinkling, and pickles on the side for a true Istanbul-style seaside experience. Eat while the fish is still warm and the bread is lightly crisp on the outside.

Pro Tips

• Choose the right fish: Oily, flavorful fish like mackerel or bluefish are most traditional for balık ekmek, but sea bass, hake, or cod also work well. Just avoid very delicate fish that fall apart easily.
• Do not over-marinate: Acidic marinades can start to “cook” the fish. About 10–15 minutes is perfect for infusing flavor without changing the texture.
• Get the pan hot first: A properly preheated grill or pan gives you light char and keeps the fish from sticking. If the fish is sticking badly, give it another 30 seconds before trying to flip.
• Slice the onions very thin: Thin slices soften quickly with salt and lemon and give that street-style onion crunch without being harsh or overpowering.
• Serve immediately: This sandwich is at its best when the fish is hot, the bread is warm, and the lettuce is crisp. Assemble right before serving rather than in advance.

Variations

• Spicier version: Add 1/2 teaspoon chili flakes (pul biber or red pepper flakes) to the fish marinade, and sprinkle extra over the finished sandwiches.
• Yogurt sauce twist: Stir together 1/2 cup (120 g) thick yogurt, 1 small grated garlic clove, a squeeze of lemon, and a pinch of salt. Spread inside the bread before adding lettuce and fish for a creamy contrast.
• Oven-roasted fish: Instead of grilling, roast the marinated fillets on a lined baking tray at 220°C / 425°F for 8–10 minutes, until just cooked through, then assemble the sandwiches as directed.

Storage & Make-Ahead

Balık ekmek is best eaten fresh, but you can prepare some components ahead. The onion and parsley salad can be made up to 4 hours in advance and kept covered in the refrigerator; bring it back to room temperature and toss before using. You can marinate the fish for up to 30 minutes in the fridge if needed, but do not go much longer due to the lemon juice. Cooked fish can be stored in an airtight container in the refrigerator for up to 1 day and gently reheated in a covered pan over low heat or in a 180°C / 350°F oven for 6–8 minutes. However, reheated fish will be a bit drier. Do not assemble the sandwiches in advance, as the bread will soften and the lettuce will wilt. Instead, store bread, lettuce, onion salad, and fish separately and assemble just before serving.
