How to Make Oil-Roasted Sardines with Mayonnaise, Pickled Onions, and Lots of Parsley

1. Preheat Oven and Season Sardines

Preheat your oven to 425°F. Season the sardines with kosher salt and freshly ground black pepper, to taste. Arrange the sardines in a 2-quart baking dish with the halved garlic heads and sprigs of fresh thyme. Drizzle ¾ cup of olive oil over everything.

2. Roast Sardines

Place the baking dish in the oven and roast the sardines for 15 to 20 minutes, until the skin crisps up and they release an enticing aroma. Remove from the oven and let cool slightly.

3. Prepare Pickled Onions

While the sardines are cooling, combine thinly sliced red onion with fresh lime juice in a small bowl. Season with salt and pepper, allowing the onions to sit and absorb the flavors for a few minutes. Toss with a cup of flat-leaf parsley leaves.

4. Serve

Arrange the sardines on a platter with a generous dollop of mayonnaise and the vibrant pickled onion mixture. Optionally, include toasted bread as an accompaniment.

Pitfalls and tips

Choose Fresh Sardines

Fresh sardines should have bright eyes, firm flesh, and a clean smell. Opt for high-quality canned sardines in olive oil if fresh ones aren't available.

Optimal Roasting Time and Temperature

Roast at a high temperature, around 400°F (200°C), and check after 10-12 minutes for crispy skin and moist flesh.

Use Quality Olive Oil

A good-quality extra virgin olive oil for roasting will add depth and a peppery note to the sardines.

Balance Layers of Flavor

Balance the richness of the sardines and mayonnaise with the acidity of the pickled onions for a harmonious flavor profile.

Arrange Sardines in a Single Layer

This prevents uneven cooking and helps the sardines crisp up nicely.
