Crustless quiche is one of those recipes you adopt once and never let go. Not because it’s trendy or because a chef talks about it, but because it solves a real everyday problem: eating well when time is short. Ten minutes of prep, an oven, and you have a complete dish that fills you up without weighing you down.
What strikes you first is that golden, slightly domed surface that comes out of the oven — nothing like the dull, flat industrial quiche we know too well. Inside, the texture is somewhere between a savory flan and a melting gratin: soft, creamy, with tomatoes that have gently released their water and ham infused into the mixture. The smell of melted cheese filling the kitchen during baking is, let’s be honest, the best reason to make this recipe on a weeknight.

Ingredient Notes
Six basic ingredients, not one more — proof that you don’t need much to eat well.
- Eggs (3 to 4) : They are the structure of the quiche — no pastry, no other binder, everything rests on them. Three eggs give a softer, creamier texture, four give something firmer that holds together better when sliced. Use eggs at room temperature: they incorporate better into the milk and avoid lumps in the batter.
- Milk (200 to 250 ml) : It brings lightness and a melting quality. Semi-skimmed milk works very well — no need to use cream, which would weigh it down. If you want a richer result, replace 50 ml of milk with heavy cream, but that’s really optional.
- Flour (2 to 3 tablespoons) : It’s the discreet binder that prevents the quiche from remaining liquid in the center. It slightly thickens the batter during baking. Don’t be tempted to add more: beyond 3 tablespoons, the texture loses its lightness and becomes dense. For a gluten-free version, rice flour works very well.
- Ham (150 to 200 g) : Prefer thick slices or dice rather than fine shreds that disappear during cooking. Classic cooked ham works perfectly, but smoked ham adds an extra depth of flavor that is very pleasant. Avoid overly salty or wet versions that could unbalance the batter.
- Tomatoes (2 to 3 medium) : Choose well-ripened firm tomatoes — classic round tomatoes are perfect. Avoid very watery off-season varieties which risk making the quiche soggy. The key: slice them into rounds and pat dry on paper towels before placing in the dish.
- Grated cheese (60 to 80 g) : Emmental or Gruyère melts well and browns nicely on top. For something more distinctive, mix Emmental and Comté. Sprinkle a first layer in the batter and a second on top: you get melted cheese inside and a slightly crispy crust on top.
The batter: whisk quickly but spoil just as quickly
Start by cracking the eggs into a large bowl and beat them for a few seconds with a whisk. Add the milk in a stream while continuing to stir — this is where lumps appear if you rush. Then incorporate the sifted flour, one spoonful at a time, and whisk until you get a smooth mixture with a slight consistency of thick pancake batter. Taste and season: salt, freshly ground black pepper, and if you like, a pinch of grated nutmeg which pairs very well with eggs. The batter should be fluid but slightly coating — if it runs like water, add half a spoon of flour before proceeding.
Tomatoes deserve proper handling
This is often where quiche fails. Poorly prepared tomatoes release their water during baking and turn the interior into a lukewarm, soggy puddle. Slice them into rounds about one centimeter thick — not too thin so they retain some bite, not too thick so they cook properly. Then lay them flat on paper towels and gently pat the top dry. If your tomatoes are particularly juicy, lightly salt them and let them sit for ten minutes before patting dry — this removes a good part of the excess water. The result is worth it: tomatoes that stay in place during baking, slightly confit, with concentrated sweetness and a hint of acidity that contrasts nicely with the creamy batter.
Assembly must be done in the right order, it’s important
Generously butter your dish — a 26 cm tart tin or a rectangular baking dish works well. First spread the ham dice evenly over the bottom so that each slice contains a good amount. Then arrange the tomato rounds on top, slightly overlapping. Slowly pour the egg batter over them to avoid moving the filling. Finally, sprinkle the grated cheese in two layers: some mixed into the batter if you want melted cheese inside, and a generous layer on top for the golden crust. At this stage, the surface should be nicely covered and even.
In the oven, patience makes quality
Bake at 180°C (350°F) in a fan oven, or 190°C (375°F) in a conventional oven, for about 30 to 35 minutes. The signs the quiche is ready: the edges are well browned, the top has taken on a beautiful amber color, and above all the center no longer trembles when you gently shake the dish. If the top browns too quickly before the center is set, cover with aluminum foil and continue for an additional five minutes. The quiche puffs up a bit during baking, then firms up as it cools — this is perfectly normal. Let it cool for at least ten minutes in the dish before cutting: it holds together much better and the silky texture that makes this dish so interesting has time to settle.
Tips & Tricks
- Always pat your tomatoes dry before placing them in the dish. The water they contain can prevent the batter from setting properly in the center, leaving you with a soggy quiche where it matters most.
- Don’t bake at too high a temperature. Above 190°C (375°F), the batter rises too quickly then collapses and becomes spongy. At a regular, moderate temperature, coagulation is slow and even — that’s what gives the sought-after melting texture.
- Let it cool before cutting. The batter continues to firm up outside the oven for several minutes. Cutting too early guarantees slices that fall apart on the plate.
- To enhance the flavor without complicating things, add half a teaspoon of whole-grain mustard directly into the batter. It doesn’t come through distinctly once cooked, but it rounds out the whole and adds a subtle kick that really makes a difference.
How to prevent the quiche from being watery in the middle?
The number one culprit is the tomatoes. They contain a lot of water that is released by heat and prevents the batter from setting properly. Always pat them dry on paper towels before placing them, and make sure the center no longer trembles before taking the quiche out of the oven.
Can the quiche be prepared ahead?
Yes, and it’s even a good idea. Once baked and cooled, it keeps for up to two days in the refrigerator, wrapped. The flavors have time to meld and the texture firms up nicely — many prefer it the next day.
Can the crustless quiche be frozen?
Technically yes, but the result is disappointing. Eggs and tomatoes don’t freeze well — the texture becomes grainy and releases water upon thawing. Better to make it fresh or keep it in the fridge for two days.
How to reheat it without drying it out?
In the oven at 150°C (300°F) for 10 minutes, covered with aluminum foil to retain moisture. Avoid the microwave, which heats unevenly and softens the top without heating the center. If you have time, take it out of the fridge 20 minutes beforehand — at room temperature, it is often very good without reheating.
Can fresh tomatoes be replaced with canned tomatoes?
It’s possible but not recommended. Canned tomatoes are much more watery and will release even more liquid during cooking, making it really difficult to achieve a firm center. If that’s all you have, drain them very thoroughly and pat dry several times — and expect a slightly longer cooking time.
Can the filling be varied?
Absolutely, that’s one of the great strengths of this recipe. Sautéed mushrooms, sliced zucchini, well-drained spinach, or roasted peppers work very well in place of or in addition to the tomatoes. The key is always the same: thoroughly remove excess water from the filling before assembling.
Crustless Ham and Tomato Quiche

- 3Season with salt, pepper, and grated nutmeg. Set aside.
- 4Slice the tomatoes into rounds about 1 cm thick. Pat them dry on paper towels on both sides to remove excess water.
- 5Spread the diced ham evenly over the bottom of the dish. Arrange the tomato rounds on top, slightly overlapping.
- 6Slowly pour the egg batter evenly over the filling. Sprinkle the grated cheese over the entire surface.
- 7Bake for 30 to 35 minutes. The quiche is ready when the top is well browned and the center no longer trembles when you gently shake the dish.
- 8Let cool in the dish for 10 minutes before slicing. Serve hot, warm, or cold.
Notes
• The step of patting the tomatoes dry is essential: it ensures a firm, not watery, center.
• If the top browns too quickly, cover with aluminum foil and continue baking until the center is set.
• For more character, replace half the grated cheese with crumbled goat cheese or Comté.
• Keeps for 2 days in the refrigerator, wrapped. Reheat in the oven at 150°C, covered with foil, for 10 minutes.
