Confit Leek Crostini

Pro tips

• Wash leeks thoroughly between all layers after halving and slicing to remove trapped soil.
• Use a low to medium-low heat throughout confiting to prevent browning; the goal is gentle, even softening, not frying.
• Toast baguette slices just before serving so they stay crisp; pre-toasted crostini will soften from the ricotta and warm leeks.
• Serve the warm confit leeks at room temperature or slightly warm for the best balance of flavors and textures.

Substitutions

• ricotta → goat cheese or whipped feta (tangier, creamier alternative)
• baguette → sourdough or ciabatta (heartier bread holds toppings better)
• olive oil → neutral oil like grapeseed or sunflower (if leeks need to be made nut-free)

Storage & make-ahead

Store cooled confit leeks in an airtight container in the refrigerator for up to one week; assemble crostini just before serving to maintain crispness.

How do I know when the leeks are done confiting?

The leeks should be completely tender and easily mashed with a spoon after about two hours. They'll have a soft, almost spreadable consistency and a deep golden color.

Can I make the confit leeks ahead of time?

Yes. Store cooled confit leeks in an airtight container in the refrigerator for up to one week, or freeze in olive oil for up to three months. Bring to room temperature before serving.

What type of olive oil should I use?

Use a neutral or mild olive oil for cooking the confit. Reserve a grassy, high-quality extra-virgin oil for finishing if desired, but it's not required.

Can I substitute ricotta with another cheese?

Yes. Goat cheese, whipped feta, or mascarpone work well and offer different flavor profiles while maintaining the creamy texture.

How should I slice the leeks for even cooking?

Halve the leeks lengthwise, wash thoroughly between layers, then slice into half-moons about ½-inch thick for consistent cooking and tender results.
