Crustless Onion & Cheese Quiche

This is a not-particularly-great looking recreation of a great dish that I taught at my weekly cooking class last Monday. In the class, we made a Swiss chard, onion and cheese crustless quiche and it was delicious. I didn't bring my camera to the class, but I wanted to post the recipe because it's so easy to make and so easy to modify with additional ingredients and flavors. So last night I made a dish similar to the one we made Monday . . . in order to photograph it . . . but I didn't have any chard or other cooking greens. The dish looked a lot better on Monday with some additional color. At any rate, yeah, this is a great foundational recipe.
I should mention at this point that a "crustless" quiche is, perhaps, an oxymoron. A quiche is a pie and pies have crusts. Julia Child, in Mastering the Art of French Cooking, has a section on quiche and the moves on to gratins, which she describes as a quiche without a crust . . . but then goes on to provide a bunch of gratin recipes with a much lower ratio of eggs to other ingredients . . . suggesting that gratins aren't simply the same quiche recipes minus the crust but, instead, substantially different concoctions. Muddling the matter even further is the fact that in this recipe I made a pseudo crust out of breadcrumbs, so the food could more easily be removed from the pie plate after baking . . . which worked really, really well, I should say. At the end of the day, I don't really know what to call this . . . and I think labels are less important than the foods behind them. So I'll call this a crustless quiche, knowing full well that someone with nothing better to do might protest such a label.
Back to the adaptability of this recipe. The foundation of this recipe consists of the eggs, milk and cream. I encourage you to make it as described here, if you feel like it . . . or throw some Swiss chard or other cooking greens in with the onions and add that to the recipe . . . or sauté the onions with some bacon . . . or add some ham . . . throw in some mushrooms . . . add your favorite spices . . . whatever floats your boat. Consider this a master recipe. If you know how to make a quiche out of 4 eggs, a cup of milk and a cup of heavy cream, then you can throw in whatever else you're in the mood for . . . or whatever else is in your fridge that needs to be eaten.
- ½ medium onion, finely chopped
- 4 eggs*
- 1 cup whole milk
- 1 cup heavy cream
- 1.5 cups cheese, grated (we used Keswick Creamery's Vermeer cheese*)
- 1 teaspoon nutmeg, grated
- Salt & pepper
- 1-2 tablespoons butter
- 1/2 cup breadcrumbs
- Preheat oven to 375°F.
- Sauté onions until soft, about 5 minutes. (Also sauté any other ingredients you'd like to add that would benefit from a sauté before baking.)
- Beat eggs lightly. Add milk, cream, cheese, nutmeg and season with salt and pepper. Fold in onion (and whatever else you're adding).
- Butter the inside surface of a deep dish 9” pie plate and then coat with breadcrumbs.
- Pour the egg mixture into the pie plate, then bake for 30-40 minutes, until no liquid seeps from the quiche when you poke it with a fork. The eggs will puff the dish up while it's baking, so if you're entertaining and want to impress the people you're feeding, carry the quiche directly from the oven to the table before it deflates!






Congrats! Trader Joe's sells a crustless quiche that was absolutely thuddy. Yours looks delicious.
Why isn't this called a savory custard?

Thanks, daddy-o. I've always thought of a custard as being more pudding-like . . . more milk and cream, less egg . . . egg white, specifically . . . resulting in less rise. We could call it a savory custard, though, if you think it appropriate.

Cindy Pawclyn served a garlic custard at Fog City Diner that was a knock out. You might check her recipe out. I think she has a cook book.
Boy, thinking about it makes me hungry.

It just has to be said: why is there no bacon involved in this? I know i am not a huge bacon aficionado, but sometimes i have to put my own tastes aside and comment based on the good of all people. I think this needs bacon.

I have nothing to say in my own defense, except for the fact that there was no bacon in my fridge when I made it . . . and for that I have no defense either. I'm truly ashamed of myself.

..i think i could almost do this one and i like to keep a few low carb foods around after certain food rich holiday weekends...my only question is...and it may be silly...BUT i never know what the recipe means when they say "fold"

I think Merriam-Webster explains folding it better than I could: "to incorporate (a food ingredient) into a mixture by repeated gentle overturnings without stirring or beating."
To fold ingredients into one another, you want to use a flat-surfaced utensil . . . any sort of spatula. For this recipe, the folding isn't at all a big deal. The recipe would turn out fine if you stirred instead of folded. But with some recipes folding is more important. I think folding has less of a tendency to disrupt the structure of the food than does stirring. For example, when adding ingredients into whipped egg whites or whipped cream, I think folding allows the whites or cream to retain more of their air than stirring would--and this is important in making foods like tira misu, when you want the food to literally be light and airy. Does this make sense? But again, I don't think folding is critical to a quiche.
