Quiche Lorraine (Silky Custard, Flaky Crust)
Classic quiche Lorraine with a silky egg custard, crispy bacon, Gruyere cheese, and a buttery, flaky blind-baked crust. The custard ratio and oven temperature control are the two techniques between watery and silky.
“Quiche Lorraine is the French breakfast that looks like a tart and eats like a custard. The custard inside should be silky and barely set — not rubbery, not watery, not airy. Getting there requires two things: the right custard ratio (more cream than milk, more yolks than whites) and a low, controlled oven temperature. Too hot and the eggs scramble into a rubbery mass. Too cool and the custard never sets. The French got this right because they understand that a quiche is an egg dish, not a cheese dish or a bacon dish — the custard is the main event, and everything else is a supporting player.”
Why This Recipe Works
Quiche succeeds when you treat it as a custard dish, not an egg dish. The distinction changes every decision: the ratio of yolks to whites, the ratio of cream to milk, the oven temperature, and the pull time.
The custard ratio is the texture. Heavy cream is about 36% fat and 58% water. Whole milk is about 3.5% fat and 88% water. When cream-based custard is heated, the fat molecules surround and lubricate the egg proteins as they denature and link together, producing a smooth, continuous gel. Milk-based custard has less fat to perform this lubrication — the proteins can cross-link too tightly and create a granular or rubbery texture. Using extra yolks (beyond the whole eggs) adds lecithin — a natural emulsifier that further smooths the custard and prevents separation. The specific ratio in this recipe (4 whole eggs + 2 yolks + 1.5 cups cream + 0.5 cup milk) produces the classic French quiche silkiness.
Low oven temperature is non-negotiable. Egg proteins denature beginning around 150°F and fully set around 175°F. At high oven temperatures, the edges of the quiche reach baking temperature while the center is still cold — the edges scramble while the center is still liquid. At 325°F, heat penetrates the custard gradually, bringing the entire quiche to the right temperature more evenly. The center still reaches 165-170°F; it just takes longer, and that time difference is what prevents the edges from overcooking.
Blind baking solves the soggy bottom. Wet custard poured onto raw pastry prevents the bottom from ever reaching the temperature needed to crisp. The moisture from the custard creates a steam environment at the bottom of the crust that essentially poaches rather than bakes the pastry. Blind baking (pre-baking with weights) sets the structure of the crust before it ever contacts the custard, producing a crust that stays crisp throughout baking.
Where Beginners Mess This Up
Before we start, read this. These are the 3 reasons your quiche lorraine (silky custard, flaky crust) will fail:
- 1
Custard is rubbery and overcooked: Oven too hot or baked too long. Quiche custard should be pulled from the oven when the center still jiggles slightly — it will set completely as it cools. Baking to full firmness in the oven means the edges have already curdled. The target temperature for finished quiche is 165-170°F at the center.
- 2
Crust is soggy on the bottom: Skipped blind baking or didn't use pie weights. Raw pastry at the bottom of a wet custard doesn't cook through — the moisture prevents browning and crisping. Blind bake the crust (10 minutes with weights, 5 minutes without) before adding the custard. A thin layer of melted cheese on the bottom also creates a barrier against sogginess.
- 3
Custard doesn't set and is watery: Too much milk relative to cream, or too many whole eggs without enough yolks. Heavy cream contains more fat and less water than milk — it produces a richer custard that sets more firmly. Yolks contain emulsifiers (lecithin) that help the custard set cohesively. The classic ratio: 4 eggs + 2 yolks to 1 1/2 cups heavy cream + 1/2 cup whole milk.

🛠️ Core Equipment
- 9-inch pie dish or tart pan with removable bottomA tart pan with a removable bottom allows you to release the quiche for clean slicing and a better presentation. A regular pie dish works but makes it harder to serve clean slices.
- Pie weights or dried beansFor blind baking the crust. Without weights, the pastry puffs up during the pre-bake and creates an uneven surface for the custard. Weights hold the pastry flat against the pan.
- Parchment paperLines the blind-baked crust to hold the pie weights without them touching and sticking to the pastry.

🛒 Ingredients
- ✦--- Crust ---
- ✦1 pre-made pie crust (or homemade — see tips)
- ✦--- Custard ---
- ✦4 large eggs
- ✦2 large egg yolks
- ✦1 1/2 cups heavy cream
- ✦1/2 cup whole milk
- ✦1/2 teaspoon salt
- ✦1/4 teaspoon white pepper
- ✦Pinch of nutmeg
- ✦--- Filling ---
- ✦6 strips thick-cut bacon, cut into lardons and cooked until crisp
- ✦1 cup Gruyere cheese, shredded (or Swiss)
- ✦1 shallot, minced and sautéed in butter (optional)
👨🍳 Instructions
01Step 1
Preheat oven to 375°F. Fit pie crust into the pan and crimp edges. Line with parchment paper, fill with pie weights or dried beans.
02Step 2
Blind bake crust for 10 minutes. Remove parchment and weights and bake 5 more minutes until the bottom is dry and pale golden. Remove from oven.
03Step 3
Reduce oven to 325°F.
04Step 4
Scatter cooked bacon (and shallot if using) over the blind-baked crust. Sprinkle cheese over the filling.
05Step 5
Whisk eggs, yolks, cream, milk, salt, white pepper, and nutmeg in a bowl until smooth but not foamy. Avoid over-whisking — foam creates bubbles in the custard surface.
06Step 6
Pour custard slowly over the filling, filling to within 1/4 inch of the crust edge.
07Step 7
Bake at 325°F for 35-45 minutes until the edges are set and the center jiggles slightly when the pan is gently shaken — like set Jell-O, not liquid.
08Step 8
Cool on a wire rack for at least 20 minutes before slicing. The custard sets completely as it cools.

🔄 Substitutions
Instead of Gruyere...
Use Swiss, Emmental, or fontina
Swiss is the most accessible substitute with a similar nutty quality. Emmental is milder and melts beautifully. Fontina is creamier and richer. All produce excellent quiche. Avoid sharp cheddar — it's too assertive and dominates the delicate custard.
Instead of Bacon...
Use Ham, smoked salmon, or caramelized onions
Ham (pre-cooked): dice and add without cooking. Smoked salmon: add to cold custard just before baking, don't pre-cook. Caramelized onions: cook 45 minutes until deeply caramelized for a French onion quiche variation.
Instead of Heavy cream + whole milk...
Use Half-and-half (2 cups total)
Half-and-half (equal parts cream and milk) is a direct substitute. The custard will be slightly less rich but still silky. Using all milk produces a looser, less creamy custard — not recommended.
Instead of Pre-made crust...
Use Crustless (just grease the pan)
A crustless quiche is significantly lower in carbs and calories. Grease the pan generously with butter and flour — the egg custard will release cleanly and you can slice it directly. The edges will be slightly crispier than the interior.
🧊 Storage & Reheating
In the Fridge
Cooled quiche covered and refrigerated for up to 4 days. Reheat at 300°F for 15-20 minutes or microwave individual slices for 60-90 seconds.
In the Freezer
Baked quiche (without crust for best results, or with crust) freezes for up to 3 months. Cool completely, wrap in foil, freeze. Thaw overnight in fridge, reheat at 325°F covered for 20-25 minutes.
Reheating Rules
Oven at 300°F for 15 minutes (whole quiche) or 10 minutes (slices) produces the best texture. Microwave works but softens the crust.
❓ Frequently Asked Questions
What makes quiche silky instead of rubbery?
The custard ratio and the oven temperature. A ratio of more cream than milk, supplemented by extra yolks (which contain emulsifiers that produce a smoother set), produces a richer, silkier custard. The oven temperature should be 325°F — low enough to heat the custard gently without causing the eggs to scramble at the edges while the center is still liquid. Pull the quiche when the center still jiggles slightly — it will set completely as it cools.
What is blind baking and do I need to do it?
Blind baking is pre-baking the pie crust without filling. For quiche, it's essential. Raw pastry at the bottom of a wet custard filling doesn't get hot enough to cook and crisp — the moisture steams the crust from the inside. Blind baking sets the crust structure before the custard is added. Line the crust with parchment, fill with pie weights or dried beans, bake 10 minutes, remove weights, bake 5 more minutes until dry.
Can I make quiche without heavy cream?
Yes, with reduced richness. Use all whole milk (2 cups total) instead of cream and milk. The custard will be slightly thinner and less silky, but still sets properly. Half-and-half (equal parts cream and milk) is the best middle option — significantly richer than all milk without being as heavy as all cream.
How do I know when quiche is done?
The jiggle test. Gently shake the pan — the edges should be firm and only the center 2 inches should jiggle, like set gelatin. The custard will continue to set as it cools, so pulling it while the center still jiggles slightly produces a perfectly set (not overcooked) quiche at room temperature. If you wait until the center is fully firm in the oven, the edges will already be rubbery.
Can I make quiche ahead of time?
Yes — quiche is excellent make-ahead. Bake completely, cool, cover, and refrigerate for up to 4 days. Serve at room temperature or slightly warm (300°F for 15 minutes). The flavors actually deepen overnight. For best crust texture, reheat in the oven rather than the microwave.
What's the difference between quiche Lorraine and regular quiche?
Quiche Lorraine is the classic: cream custard, Gruyere, and bacon (lardons). Other quiches use different fillings — vegetables, other meats, other cheeses — but the custard base is the same. Quiche Lorraine is the French original; everything else is a variation. The name comes from the Lorraine region of France, which borders Germany and has a long tradition of using bacon and cream.
Why is my quiche watery?
Two likely causes: too much milk relative to cream (more water content in milk means more liquid that doesn't bind fully), or wet vegetables that released moisture during baking. For the custard: use the cream-forward ratio. For vegetables: always pre-cook them and pat dry before adding to the quiche — mushrooms, spinach, and zucchini contain enormous amounts of water that release during baking.
Can I make individual quiches in a muffin tin?
Yes. Cut circles of pie crust to fit muffin cup bottoms and sides. Press in, trim edges. Add filling and custard. Bake at 350°F for 18-22 minutes until set. Individual quiches are ideal for brunch service — no slicing needed, portable, and visually attractive.
