Iwashi Shioyaki Recipe (Salt-Grilled Sardine)

How to Make Perfectly Crispy Iwashi Shioyaki (Salt-Grilled Sardines)

Ingredients (Serves 2–4)

INGREDIENTS QUANTITY
Fresh iwashi (Japanese sardines) 4
Sea salt 1–2 tbsp
Lemon wedges or lime As desired
Grated daikon (daikon oroshi, optional) 6 oz (180 g)
Soy sauce (for dipping, optional) 4 tbsp (60 ml)

Instructions

  1. Prepare the Sardines: Rinse the sardines under cold water and pat them dry with paper towels. Make shallow slashes along each side to help them cook evenly and allow the salt to penetrate. Sprinkle sea salt generously on both sides and inside the cavity. Let them sit for 10–15 minutes to draw out moisture and enhance flavor.
  2. Preheat the Grill:
    • Outdoor grill: Preheat to 375–400°F (190–200°C). Use a fish grilling rack to make flipping easier and prevent sticking.
    • Oven broiler: Preheat to high (500°F or about 260°C). Place the oven rack about 6 inches from the heating element.
  3. Grill the Sardines: Place the sardines on the grates and cook for about 3–4 minutes on each side. Flip gently using a spatula or tongs to avoid breaking the fish. The skin should be crispy, and the flesh tender and opaque.
  4. Serve: Transfer the grilled sardines to a plate and serve with lemon or lime wedges.
  5. Garnish and Enjoy: Add grated daikon (optional) and soy sauce for dipping to enhance the flavors further.
