LITTORALICIOUSA quiche fails in three places, none of them flavour: a scrambled, weeping custard, a wet base, a slice that collapses on the plate. Fix those three and the garnish is almost incidental — the dish was a custard long before it was bacon.
The one idea: quiche is a barely-set savoury custard in a crisp shell — not a cheese pie. Weigh the appareil, seal the base, bake it low and pull it at a jiggle. Everything else is decoration on top of those three moves.
For all its French reputation, quiche is a German word — from Kuchen, cake — a relic of Lorraine’s centuries on the shifting Franco-German border (the region is still Lothringen in German). The original quiche Lorraine had no cheese at all: just smoked bacon and a plain custard of egg and cream, the migaine, poured into bread dough rather than pastry. The Gruyère and the shortcrust came later, after 1900, and Lorraine purists still call them heresy.
That history is why this recipe is built custard-first. The thing the people of Lorraine never changed — through four centuries and a dozen border redraws — is the principle: a savoury custard, set soft, with just enough structure to slice. Treat the egg-and-dairy ratio as the recipe and the bacon as a topping, and you are cooking the dish it actually is.
The oldest paper trail for quiche is an account-book entry, not a recipe. In the March 1586 statement of expenses for Charles III, Duke of Lorraine, his household paid the baker « 9 gros pour échaudés & quiches » — nine gros for fritters and quiches. The word itself surfaces in writing soon after, in the Lorrain dialect at Nancy in 1605; it only reached standard French around 1810, and English (as “quiche lorraine”) not until 1925. — Oxford English Dictionary, quiche; National Geographic, 2023
The romance is in the ducal account book. What actually separates a clean slice from a weeping one is a single number you can’t see on the plate — the temperature the egg reaches.
Egg proteins start knitting into a gel around 62°C and lock up by about 85°C. Pushed too hot, the network over-tightens and squeezes its own water out — that is the grainy, weeping curd, the same syneresis that ruins scrambled eggs. The fix is twofold: bake low so the set creeps up gently, and load the mix with yolks. Yolk lecithin and fat, plus the dilution from all that milk and cream, hold the proteins apart so the custard sets tender instead of rubbery. — McGee 2004; American Egg Board

The ratio — memorise, rescale anything
1 L dairy → 8 whole eggs + 2 yolks · dairy 60% milk / 40% cream · salt ~1%. Push to 6 eggs/L for a softer plated custard, 12 eggs/L for a firm quiche that survives a passage. The extra yolks are what keep it tender, not rubbery.Ingredients
Method
-
The 1586 original used bread dough; we use pâte brisée for the same reason — a wall sturdy enough to hold a litre of custard without slumping.
Blind-bake the shell. Line the oiled 1/2 GN with 400 g-flour brisée, dock, rest cold 30 min. Bake 180°C (350°F) with beans 20 min, then 8–10 min uncovered until dry and pale gold. (Faster: thaw frozen all-butter shortcrust and skip the dough.)
Why
A raw shell never recovers under wet custard. Blind-baking dries and sets the walls so the base is crisp before a drop of appareil touches it. — Keller, Bouchon -
The single move that ends the soggy bottom — a fix professional kitchens swear by and home cooks skip.
Seal it. Brush the hot inside with beaten egg, back in for 2 min until set to a dry sheen. Trim the overhang.
Why
The egg coagulates into a waterproof film over the dried base — the single fix for the soggy bottom under wet custard. — López-Alt, Serious Eats; Keller -
In Lorraine the garnish was only ever smoked pork; everything else is a later guest at the table.
Garnish — cook & drain hard. Render 350 g bacon; sweat the onions in a little of the fat until sweet and dry. Drain both until no fat pools.
Why
Every gram of water in the garnish leaches into the custard and stops it setting — a layer of weep at the seam. Drain harder than feels right. — McGee 2004 -
This is the migaine — the Lorrain name for the egg-and-cream mix that is the quiche.
The appareil. Whisk 12 eggs + 3 yolks + 800 g milk + 600 g cream + seasoning. Blend, don’t aerate, then strain and skim until smooth and foam-free.
Why
Yolk lecithin and fat set lower and softer than white — silk without rubber. Straining removes the chalazae and whisked-in air for an even, blemish-free set. — McGee; Keller -
Cheese on the base is a second seal — a fatty raft between custard and pastry.
Build & fill. Half the cheese on the sealed base, then bacon + onion, then the rest. Set the pan on the oven rack first, then pour the appareil to ~5 mm below the rim.
Why
Filling a full, slack pan on the bench guarantees a spill on the way to the oven — on a moving boat, doubly so. Pour in place. — Tested at sea -
The whole dish lives or dies on this one temperature — the number from the read.
Bake low — 150°C (300°F), 45–55 min. Pull when the edges are set but the centre jiggles like soft jelly (73–75°C internal). Rest 20–30 min — carryover firms it to ~80°C — then cut 2×5.
Why
Egg sets from ~62 to 85°C; hotter and the proteins seize and squeeze out water — the grainy, weeping quiche. Low and slow is the only clean set, and carryover finishes the middle as it rests so you never chase it in the oven. — McGee; Modernist Cuisine
In Lorraine a quiche is an entrée, eaten warm rather than hot — cut into squares with a sharp green salad and a glass of dry Alsace or Mosel white to cut the richness. It is also the perfect cold-leg crew food: a slice holds its shape at room temperature, travels in a lunchbox without weeping, and asks for nothing but pickles or a tomato salad alongside.
Take it further
| Crustless | Butter the GN, dust Parmesan + breadcrumb, build straight in — fastest at sea, and the appareil and bake are unchanged |
| Quiche au saumon | Hot-smoked salmon and dill in place of the bacon — a Northern-French standard |
| Leek + smoked haddock | 250 g poached and flaked, leeks not onion — cuts the richness and reads as a tart, not a pie |
| Tarte flambée cousin | Lorraine’s Alsatian neighbour: crème fraîche, onion and lardons on thin dough, no egg — the same trio, no custard |
| Comté + a little blue | Swap 40 g of the Gruyère for a young blue — depth without tipping into a cheese pie |
| All-cream, more yolks | 1 L cream, 6 eggs + 6 yolks — the plated-dessert silk; serve in slim wedges |
| Roast cherry tomato + basil | Roast the tomatoes first to drive off water, or they weep into the set |
One base, two dishes — the brisée fruit tart
The pâte brisée under this quiche is the same dough that lines a French tarte aux fruits; add 60–80 g sugar to the flour and you have pâte brisée sucrée, the neutral shortcrust French pastry uses for both the savoury custard tart and the sweet one. Make a double batch of dough and run one shell each way across a charter.
| Sweeten the dough | Add 60–80 g caster sugar to the flour; otherwise mix, rest and blind-bake exactly as the quiche shell |
| Seal the same way | Egg-wash the hot blind-baked base, or brush with melted apricot jam — the sweet version of the waterproof seal |
| Fill it | A thin layer of crème pâtissière, then sliced stone fruit or berries fanned on top — no second bake for soft fruit |
| Custard route | Or pour a sweet appareil — same egg:dairy ratio, sugar instead of salt — over sliced apple or pear and bake low, the way you bake the quiche |
Troubleshooting
| Soggy bottom | Shell under-baked or unsealed → fully blind-bake, egg-wash, and lay cheese on the base |
| Grainy, weeping | Baked too hot or too long → 150°C only, and pull at the jiggle / 73–75°C |
| Won’t set | Too much dairy or a wet garnish → weigh to the ratio and drain the garnish hard |
| Rubbery slice | Too many whole eggs, no yolks → hold 8+2 whole eggs and yolks per litre of dairy |
| Streaky, bubbled top | Over-whisked or unstrained → blend only, then strain and skim the foam |
| Cracked, deflated | Oven too hot — it souffléed then fell → lower the heat; a quiche should never puff |
| Pale, flabby custard | Under-baked at the centre → chase 73°C with a probe, not the clock; ovens lie |
Charter prep & storage
Quiche is built for staggered service — it is as good at room temperature as hot, so it carries a whole watch of mismatched meal times without a reheat.
| Blind shell | 1 day, wrapped at room temp; re-crisp 5 min at 160°C before filling |
| Cooked garnish | 2 days in the fridge, airtight and separate; drain again before it goes in |
| Strained appareil | 1 day in the fridge in a jug; re-skim before pouring |
| Baked, whole | 3 days in the fridge; superb at room temp, or reheat 150°C / 12–15 min for staggered crew meals |
| Frozen | 1 month; thaw in the fridge and reheat 160°C / 20 min |
| Scale up | One 1/2 GN feeds 10–12; a full GN doubles it for a combined crew-and-guest lunch |
On a moving boat, fill the pan on the rack and bake low — a slack appareil and a slamming swell are no friends. The low set is forgiving of an oven that won’t sit still.
Once the ratio is yours — 1 L dairy, 8 eggs, 2 yolks — the rest is yours to improvise: swap bacon for smoked salmon, build it crustless for speed at sea, or push to 12 eggs per litre for a firm quiche that survives a passage. Feeding crew and guests off one bake, run a full GN and cut it 2×6. Four hundred years on, it is still what the people of Lorraine made — a custard, set soft, with smoke folded through it. Weigh the custard and the rest looks after itself.
