Grilled Sardines with Caramelized Onion and Lemon

Instructions

1. 1

   Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for 20-25 minutes until they turn golden brown and caramelize, developing a sweet flavor.

   Tip: Don't rush the caramelization process—low and slow heat creates the best flavor.

2. 2

   In the last 5 minutes of cooking the onions, add the minced garlic and cook until fragrant. Stir in the white wine vinegar and remove from heat. Season with salt and pepper to taste.

   Tip: The vinegar adds brightness and prevents the onions from becoming too sweet.

3. 3

   While the onions cook, pat the sardines dry with paper towels and season both sides generously with sea salt and black pepper. Brush lightly with remaining olive oil.

   Tip: Dry sardines grill better and develop crispier skin.

4. 4

   Preheat your grill to medium-high heat (around 400°F). If using a grill pan, preheat it on the stovetop until it's very hot.

   Tip: A hot surface ensures the sardines cook quickly and get nice grill marks.

5. 5

   Place sardines perpendicular to the grill grates and cook for 3-4 minutes per side until the skin is crispy and the flesh is cooked through. Arrange fresh thyme sprigs on top during cooking.

   Tip: Don't move the sardines around too much—let them develop a beautiful crust.

6. 6

   Transfer the grilled sardines to a serving platter. Top with the warm caramelized onions and drizzle with fresh lemon juice. Garnish with chopped parsley and serve with lemon wedges.

   Tip: Serve immediately while the sardines are still warm for the best texture.
