Avocado oil swaps 1:1 by cup for both the pressed crust and the 1 tbsp in the custard. Its neutral flavor lets egg, cream, and fillings lead; pour custard at room temp into the egg-white-sealed shell and bake at 325°F for 35-45 minutes until the center 3 inches still jiggle.

Corn oil swaps 1:1 by tablespoon with matching neutral flavor to peanut oil. Use it in both the blind-baked crust and as the 1 tbsp custard enrichment; pour at room temperature into the sealed shell and bake 325°F until the outer 2 inches set and the center still jiggles softly.

Rice bran oil swaps 1:1 by tablespoon and its mild sweetness pairs naturally with rich egg-cream custard. Use in crust and 1 tbsp in filling; pour room-temp custard into sealed shell, bake at 325°F for 35-45 minutes — silky set and golden jiggly wedge match peanut oil exactly.

adjustment for this dish
Grapeseed oil swaps 1:1 by cup with ultra-neutral flavor that lets fillings shine through. Use 1 tbsp in the 4-egg custard; the cream-and-egg emulsion sets silky at 325°F over 35-45 minutes, and the wedge cuts cleanly after a 15-minute rest just as peanut oil quiche does.

adjustment for this dish
Olive oil swaps 1:1 by cup and brings Mediterranean richness that pairs with spinach, feta, or herb fillings. Use light-tasting refined olive oil for classic Lorraine to keep flavor clean; 1 tbsp in the custard sets silky at 325°F with the center still jiggling at 40 minutes.

technique for quiche
technique
Peanut oil in quiche custard enriches the egg-cream mixture (4 eggs + 1 1/2 cups heavy cream + 1 tbsp oil per 9-inch shell) so the filling sets silky rather than weepy or curdled when baked. Blind bake the crust to golden at 400°F for 20 minutes with weights, brush the hot shell with beaten egg white to waterproof, then pour the custard in slowly at room temperature.
Bake at 325°F for 35-45 minutes until the outer 2 inches are set but the center 3 inches still jiggle when nudged — carryover heat finishes it during a 15-minute rest so the wedge cuts cleanly. Unlike omelet, where oil lubricates a pan for a 90-second stovetop fold at 300°F, quiche oil is suspended inside the custard and cooks via slow oven convection for rich, sliceable filling.
Overbake past 170°F internal and the egg proteins contract, squeezing water out and turning the texture grainy.
pitfalls to avoid
watch out
Brush the hot blind-baked crust with beaten egg white before pouring custard; unprotected crust soaks up liquid from the cream filling and the wedge bottom turns soggy.
watch out
Pull from the 325°F oven when the center 3 inches still jiggle; overbaking past 170°F internal curdles egg proteins and the filling weeps water during the rest.
watch out
Pour custard at room temperature, not cold from the fridge; cold liquid hitting a 400°F hot shell cracks the crust and sends the rich filling leaking out the side.
watch out
Rest 15 minutes before slicing wedges; early cutting tears the just-set custard and the slice collapses on the plate instead of holding a clean cross-section.
watch out
Strain the custard through a fine mesh before pouring into the shell; stray chalaza or shell bits create lumpy set spots that mar the smooth golden top.
