Onion Brussels sprouts and potato quiche slice

Recipe Overview

This quiche brings together the comfort of potato, the sweetness of caramelized onion, the earthy edge of Brussels sprouts, and a creamy egg custard baked inside a crisp brisée crust.

Chef Notes

Blind-baking and sealing the brisée crust helps keep the shell crisp. Rest before slicing so the custard sets cleanly for appetizer or buffet service.

Ingredients

Base recipe = 8. Minimum production = 8 servings.

Preparation

Production timing: 35 active prep min · 55 passive prep min · 70 cook min · 8 plating min · 10 cleanup min.
  1. Cook the potato and prepare the vegetables: Wrap the Idaho potato in foil and bake at 350°F for about 45 minutes. Cool and dice. Blanch Brussels sprout petals or leaves and drain well. Slice the onion thin and slowly caramelize in olive oil.
  2. Mix the custard: Whisk together heavy cream, eggs, nutmeg, salt, and pepper. Fold in the diced potato, blanched Brussels sprouts, and caramelized onion. Refrigerate while preparing the crust.
  3. Blind-bake the crust: Roll brisée dough to fit a 12-inch tart pan. Line the pan, add parchment and weights, and bake at 350°F for about 22 minutes. Remove weights, brush with beaten egg, and bake 2 minutes more to seal.
  4. Final bake: Fill the shell with the custard mixture, sprinkle Parmigiano Reggiano over the top, and bake at 325°F for 35 to 45 minutes until just set in the center. Rest 10 minutes before slicing.
