Nov 25th 2025
This flavor packed crostini is great as a snack for a cocktail party. You can either leave the components deconstructed and encourage your guests to build their own perfect bites, or have them all dolled up and ready to devour.
Serves 2-4 as a snack
Ingredients
For the caper butter
- ¼ cup (2 ounces) unsalted butter, at room temperature
- 1 tablespoon brined capers, roughly chopped
For the caramelized leeks
- 2 tablespoons unsalted butter
- 2 leeks, white part only, halved longways and thinly sliced
- Fine sea salt to season
- Zest and juice of half a lemon
For the crostini
- Sourdough bread
- Olive oil for frying
- 1-2 cans Ekone Lemon Pepper Oysters
- Zest of half a lemon
Instructions:
- To make the caper butter, combine the softened butter and capers in a small bowl until combined.
- To caramelize the leeks, heat a small sauté pan over medium-low heat.
- Add the butter and swirl to coat the pan. Add the sliced leeks and a generous pinch of salt.
- Cook, stirring occasionally, until the leeks have fully softened and begin to brown. You’re going for gooey, golden edges. It will take about 15 minutes.
- When you’ve achieved the desired consistency, take the pan off the heat and season the leeks with lemon zest, lemon juice, and another pinch of salt if necessary.
- To build the crostini, start by frying your bread. Heating a large, heavy bottomed skillet over medium-high heat. Drizzle one side of each piece of bread generously in olive oil, and place them oiled-side down in the hot skillet.
- Weigh the bread down with a steak weight or another small pan to help achieve a deeply golden crust. Flip the toast and repeat on the other side.
- Set the bread aside to cool for a few minutes, so that the butter won’t melt on contact. When the bread is cool enough to handle, cut it into quarters.
- Smear on the butter, layer on the caramelized leeks, then top each piece of toast with a Lemon Pepper Oyster.
- Finish with more lemon zest.
