A low-effort crustless quiche can be adapted to the seasons, as perfect for weeknight dinner as it is for weekend brunch. This one is flecked with zucchini, salty cheese and fragrant scallions, and though it feels sunny and summery, it can be prepared year-round. Grating the zucchini is key to achieving the supple texture, allowing the liquid to be easily squeezed out while retaining just enough moisture to keep the egg base light and silky, with an irresistible custard-like consistency. Like French clafoutis, this crustless quiche has a touch of flour, which stabilizes the custard and delivers a firm-yet-jiggly texture. Feta’s sharp tang enlivens zucchini’s mellow earthiness, while Cheddar, preferably aged, brings essential saltiness. Serve this dish warm or at room temperature, alone or with a side salad.

Preparation

    1. Step 1

      Place the grated zucchini in a colander, sprinkle with 1 teaspoon of salt and toss to coat. Leave for 5 minutes.

    2. Step 2

      Heat the oven to 350 degrees. Drizzle the olive oil into a 9-inch round or oval baking dish and tilt it to allow the oil to cover the base and sides.

    3. Step 3

      Meanwhile, add the milk and eggs to a large bowl and whisk to combine. Add the flour, season with ½ teaspoon each of salt and pepper, and whisk just until there is no more dry flour. (A few small lumps are OK.) 

    4. Step 4

      Squeeze the zucchini to remove as much water as possible. (It doesn’t have to be completely dry.) Add the zucchini to the egg mixture, along with the feta, half of the Cheddar and half of the scallions, and fold to distribute evenly. 

    5. Step 5

      Pour the mixture into the prepared dish. Top with the remaining Cheddar and scallions.

    6. Step 6

      Bake until the center is just set, 35 to 40 minutes. (Insert a toothpick into the center and if it comes out clean, it is ready.) Remove from the oven and allow to cool for 10 minutes. Run a knife around the edge to loosen and then cut into wedges or squares. This crustless quiche can be served hot, at room temperature or cold.

Made tonight just as written and it came out perfectly in 35 min. Might cut out the 1/2 tsp salt in the batter as the cheeses have plenty of salt. Also might add a few sautéed mushrooms and/or roasted red bell peppers. Was easy and pretty straightforward. We’re thinking of using it for breakfast or brunch with overnight guests.

@MB Williams- do you think this can be prepped the night before ?

This recipe is very much like a frittata. Many vegetables can be substituted while keeping in mind the measurements. Being of Greek heritage, I am addicted to authentic/ imported /Greek/ goat/ sheep milk feta.However, French feta is also excellent. If briny cheese is not your favorite, any cheese can be substituted. No matter the vegetable used, I always add a quarter teaspoon of nutmeg. I made it yesterday using leftover chopped asparagus and mushrooms. Excellent recipe!

Made this tonight for supper. Absolutely delicious ! I did add the Roasted Red Peppers into it and followed the advice to leave the 1/2 teaspoon of salt out as the Feta has salt. Tastes spot on. Sprinkles finely crushed red pepper seeds on top. Keeper.

Well, we had this for supper tonite. FANTASTIC flavor combinations. I can see why folks are raving about it. Husband absolutely loved it. I did sub out the chili powder for Smoked Paprika and swapped for the sweet potatoes as others mentioned. Perfect. Served it with all the accompaniments. So delicious. Company worthy ! This is a keeper.

I made this tonight and it was delicious. I added half a bunch of sautéed Swiss chard. I sautéed the stems with a chopped onion until soft, then cooked the leaves. I let it cool before adding to the egg mixture.
