Stuffed Sardines

Sardinas rellenas

Sardines are one of the treasures of the Mediterranean, famous for their high Omega-3 content and intense flavor. This recipe turns humble blue fish into a sophisticated dish thanks to an aromatic, nourishing filling. The contrast between the juicy texture of the fish and the vegetable and nut filling creates a complete dining experience. By using Bonsalt, we enhance the fish’s natural marine flavor without adding sodium, thereby protecting your cardiovascular health and helping prevent fluid retention.

Step-by-Step Professional Preparation

  1. Cleaning: Make sure the sardines are well cleaned, scaled, and fully butterflied (with the central bone removed). Drizzle with a little lemon juice and set aside.

  2. Filling preparation: Finely chop the onion and garlic.

  3. Sautéing: In a skillet with a tablespoon of EVOO, sauté the onion and garlic until tender. Add the pine nuts and raisins, cooking for a couple of minutes until the nuts are lightly browned.

  4. Seasoning and texturizing: Off the heat, add the chopped parsley, black pepper, breadcrumbs, and half a teaspoon of Bonsalt . Mix well until you have a consistent filling.

  5. Assembly: Season the sardine flesh with the rest of the Bonsalt. Place a teaspoon of the filling on one open sardine and cover it with another sardine (like a sandwich), or simply roll it over the filling.

  6. Cooking technique: Place the sardines on a baking tray brushed with EVOO. Bake at 200°C for about 10-12 minutes. Do not overcook so the fish stays juicy.

  7. Finishing: Serve with a slice of fresh lemon to brighten the whole dish.

Nutritionist’s Tips

Sardines are an excellent source of calcium, especially if you eat the small bones that may remain. By using Bonsalt , we remove the sodium that usually comes with fish preparations, which helps promote better fluid balance and arterial health. The unsaturated fats from the pine nuts and EVOO perfectly complement the fish’s Omega-3, creating a protective shield for your heart.

It’s a delicious, traditional, heart-healthy recipe to share with friends or family!
