Sardines

This recipe turns four cans of sardines into something that belongs on a bistro menu. The oil packed in the cans becomes the cooking fat for a soft, sweet relish of sliced onions, fennel, and garlic. Nothing wasted, nothing extra needed.

Three large onions and two fennel bulbs cook down slowly in the sardine oil until completely soft but not browned. That five minutes of gentle cooking melts the fennel’s anise bite into something mellow and sweet, while the sardine-flavored oil adds a savory depth you’d never get from plain olive oil.

White wine deglazes the pan after the relish is plated, simmering for a few minutes before the sardines go in to warm through. The wine cuts the richness of the oily fish and adds acidity that brightens the whole dish.

The sardines only need a brief warming. They’re already cooked in the can. Too much heat and they fall apart into mush. You want them heated through and glistening with the pan juices, then laid over the fennel-onion bed.

Kitchen Tips

• Drain the sardine oil carefully into the pan. Every drop of that oil carries flavor. Don’t waste it.
• Slice the onions and fennel thin. Thick slices won’t soften in five minutes and you’ll end up with crunchy vegetables under your fish.
• Don’t brown the vegetables. You want them silky and translucent, not caramelized. Keep the heat at medium.
• Handle the sardines gently. They’re delicate. Use a fish spatula or wide spoon to transfer them so they stay whole.

Variations

• Lemon finish: Squeeze fresh lemon juice over the plated dish and scatter capers for a Sicilian touch.
• Crusty bread pairing: Serve on thick slices of grilled sourdough rubbed with garlic for an open-faced bruschetta presentation.
