Leek Welsh Rarebit

The leek is a national emblem of Wales, making this perhaps the most authentic "Welsh" Rarebit. Leeks are milder and sweeter than onions, and when sautéed in butter, they become creamy, blending perfectly into the cheese sauce. This dish is a must-have on St. David's Day.

Instructions

1

Slice the leek into thin rounds. Sauté in the extra butter over low heat until soft but not browned.

Tip: "Sweating" the leeks softens and sweetens them without developing bitterness.
2

Make the cheese sauce: roux of butter and flour, whisk in milk, simmer until thick.

Tip: Patience is key for a smooth base.
3

Remove from heat. Stir in cheese, spices, and the softened leeks.

Tip: The leek fibers add texture to the cream.
4

Toast the bread and top with the leek cheese mixture.

Tip: The thicker the layer, the better.
5

Broil until golden brown.

Tip: Serve hot.

Recipe FAQ

Can I use green onions?
Yes, but leeks offer a deeper, sweeter flavor. If using green onions, add them at the very end.
How do I clean leeks?
Slice lengthwise and wash thoroughly under running water to remove grit trapped between layers.
