Full Ingredients
Fish and Smoky Spice Rub
- 4 mackerel fillets (about 150 g each; 600 g total), skin-on preferred
- 30 ml (2 tbsp) olive oil
- 2 tsp smoked paprika
- 1 tsp ground cumin
- 1 tsp kosher salt
- 1/2 tsp freshly ground black pepper
Onion and Crunchy Fillings
- 1 medium red onion (about 150 g), very thinly sliced
- 1 tsp sumac (optional but highly recommended)
- 1/8 tsp kosher salt (a small pinch)
- 120 g shredded lettuce (romaine for crunch, iceberg for classic street-food snap)
- 80 g pickled peppers (optional), drained and sliced if large
Bread and Serving
- 4 crusty sandwich rolls (80–100 g each), split lengthwise
- 15 ml (1 tbsp) olive oil (for toasting rolls)
- 1 lemon, cut into wedges (plus extra lemon if you want it extra bright)
Step-by-Step Instructions
Step 1: Prep the onion topping
In a small bowl, toss the thinly sliced red onion with 1 tsp sumac and a small pinch (about 1/8 tsp) kosher salt. Use your hands to gently massage the onions for 10–15 seconds to soften them slightly. Set aside for 10 minutes while you prepare the fish. This quick rest takes away the harsh edge and gives you that classic Istanbul street-food bite.
Step 2: Season the fish for smoky flavor
Pat the mackerel fillets dry with paper towels (this helps them sear instead of steam). Drizzle with 30 ml (2 tbsp) olive oil, then sprinkle evenly with 2 tsp smoked paprika, 1 tsp ground cumin, 1 tsp kosher salt, and 1/2 tsp black pepper.
Rub the seasoning over the flesh (and lightly over the skin side too). Let the fish sit at room temperature for 5–10 minutes while you heat the grill.
Step 3: Heat your grill (or grill pan) properly
Preheat an outdoor grill to high heat, 230–260°C. If using a grill pan, preheat it over medium-high until very hot, about 4–5 minutes.
For outdoor grilling, clean and oil the grates. For a grill pan, you can brush the pan lightly with oil, then wipe out any excess with a folded paper towel held with tongs (you want a thin film, not puddles).
Step 4: Grill the mackerel until juicy and flaky
Place the fillets on the grill skin-side down first. Grill for 4–5 minutes without moving them much, so the skin crisps and releases cleanly.
Carefully flip and cook 1–3 minutes more, depending on thickness, until the fish is opaque and flakes easily.
Food-safety check: The thickest part of the fish should reach an internal temperature of 63°C.
Step 5: Toast the rolls for the best texture
Brush the cut sides of the rolls with 15 ml (1 tbsp) olive oil total. Toast cut-side down on the grill (or in the grill pan) for 1–2 minutes, just until warm with light char marks and a crisp edge.
This step keeps the bread from getting soggy once the lemon hits the fish.
Step 6: Assemble the balık ekmek sandwiches
Work quickly while the fish is hot. On the bottom half of each roll, layer:
1) A small handful of shredded lettuce
2) A generous pinch of the sumac onions
3) One grilled mackerel fillet (or break larger fillets into big chunks)
4) Pickled peppers (optional), to taste
Cap with the top half of the roll.
Step 7: Finish with lemon and serve immediately
Right before serving, squeeze 1–2 lemon wedges over each sandwich (or serve wedges on the side so everyone can adjust the acidity). Serve immediately while the bread is warm and the fish is at its juiciest.
Pro Tips
- Choose the right fish: Mackerel is classic, but any oily fish that grills well works. Aim for fillets that are about 2–3 cm thick so they don’t overcook.
- Don’t fight the flip: If the fish sticks, give it another 30–60 seconds. Once the skin crisps, it releases more easily.
- Keep the crunch: Dry the lettuce well and toast the bread. These two steps prevent a soggy sandwich.
- Sumac makes it taste “street”: That lemony, tangy sumac-onion bite is a big part of the iconic flavor. If you can find it, use it.
- Temperature matters: Pull the fish right at 63°C to keep it moist. Mackerel dries out quickly if overcooked.
Variations
- Use sardines or herring: Grill whole sardines (scaled and gutted) or use herring fillets; cook times may be slightly shorter, about 2–3 minutes per side depending on size.
- Oven broiler method (no grill): Broil on a lined sheet pan 10–12 cm from the element at high broil for 3–5 minutes, then flip and broil 2–4 minutes to 63°C. Toast rolls in the oven for 2 minutes.
- Add extra heat: Along with pickled peppers, add 1/4 tsp Aleppo pepper or red pepper flakes to the fish rub.
Storage & Make-Ahead
Best fresh: These sandwiches are at their peak right after grilling.
Store leftovers: Refrigerate leftover grilled fish in an airtight container for up to 2 days. Store lettuce, onions, and bread separately.
Reheat: Warm fish in a 175°C oven for 8–10 minutes (or in a skillet over medium heat for 2–3 minutes), just until heated through. Toast the bread again if possible.
Make-ahead: Slice the onions and toss with sumac and salt up to 24 hours ahead; refrigerate. Shred lettuce up to 1 day ahead and keep it very cold and dry.
