📝 About This Recipe

It is a masterclass in balancing salt, acid, and fat, making it the perfect quick lunch or an elegant appetizer for your next gathering.

🥗 Ingredients

The Foundation

  • 2 thick slices Sourdough Bread (preferably 1-inch thick)
  • 1 piece Garlic Clove (peeled and left whole for rubbing)
  • 2 tablespoons Extra Virgin Olive Oil (high quality for drizzling)

The Sardines

  • 1 can Sardines in Olive Oil (approx. 4.25 oz, bone-in for extra calcium and flavor)
  • 1/4 teaspoon Smoked Paprika (pimentón de la Vera)
  • 1 pinch Red Chili Flakes (adjust to heat preference)
  • 1 tablespoon Unsalted Butter (cold)

The Gremolata & Toppings

  • 1/4 cup Fresh Flat-Leaf Parsley (finely chopped)
  • 1 piece Lemon (zested and cut into wedges)
  • 1 small Shallot (very thinly sliced into rings)
  • 1 tablespoon Capers (drained and patted dry)
  • 1 pinch Flaky Sea Salt (like Maldon)
  • 1 pinch Black Pepper (freshly cracked)
  • 2 pieces Radishes (thinly sliced for crunch)

👨‍🍳 Instructions

  1. 1

    Open the tin of sardines and carefully pour the oil into a small skillet. Set the sardines aside on a plate, being careful not to break them.

  2. 2

    In a small bowl, combine the finely chopped parsley, lemon zest, and a tiny pinch of salt to create your gremolata. Set aside to let the aromas meld.

  3. 3

    Heat a cast-iron skillet or griddle pan over medium-high heat. Brush both sides of your sourdough slices with a little extra virgin olive oil.

  4. 4

    Place the bread in the hot skillet and toast for about 2-3 minutes per side until deeply golden and charred in spots. The edges should be crisp while the center remains slightly chewy.

  5. 5

    Remove the toast and immediately rub one side of each slice with the raw garlic clove. The heat of the bread will melt the garlic into the crust.

  6. 6

    In the skillet containing the reserved sardine oil, add the butter, smoked paprika, and chili flakes. Heat over medium until the butter foams.

  7. 7

    Add the sardines to the skillet. Cook gently for about 1-2 minutes on each side just to warm them through and infuse them with the spiced oil. Do not overcook or they will become dry.

  8. 8

    While the sardines warm, place the sliced shallots in a small bowl with a squeeze of lemon juice to lightly pickle them for 2 minutes.

  9. 9

    Place the garlic-rubbed toast on serving plates. Arrange the warmed sardines artistically across the bread.

  10. 10

    Drizzle the remaining spiced oil and butter from the pan over the sardines and bread.

  11. 11

    Top the sardines with the shallot rings, sliced radishes, and capers.

  12. 12

    Generously sprinkle the gremolata over the top, finish with a flourish of flaky sea salt and cracked pepper, and serve immediately with lemon wedges on the side.

💡 Chef's Tips

Always look for 'Vintage' or high-quality tinned sardines in extra virgin olive oil; the cheaper versions in water lack the necessary richness. If you find the flavor of sardines too strong, soak them in a little milk for 10 minutes before cooking to mellow the 'fishiness'. Don't skip the garlic rub; it provides a foundational aromatic layer that cuts through the oiliness of the fish. Ensure your bread is toasted enough to handle the weight and moisture of the toppings without becoming soggy.

🍽️ Serving Suggestions

Pair with a crisp, dry white wine like a Portuguese Vinho Verde or a Spanish Albariño to cut through the fat. Serve alongside a simple arugula salad dressed with lemon and olive oil for a complete light lunch. A chilled glass of dry Fino Sherry is a traditional and sophisticated accompaniment. For a brunch twist, add a soft-boiled egg or a dollop of crème fraîche on top.
