Author Notes

There's a lot to love about this quiche, from the clever trick of adding a dollop of both grainy mustard and sour cream to the filling for richness and flavor, to the easy press-in crust made with oats for a nuttier taste.

What You'll Need

Ingredients
  • For the crust
  • 1 cupquick-cooking oats
  • 1 cupall-purpose flour
  • 1/2 teaspoonsalt
  • 4 tablespoonsoil (olive oil, vegetable oil, or coconut oil all work)
  • 5-6 tablespoonscold water, plus more as needed
  • For the filling
  • 4 eggs
  • 2 cupsmilk
  • 2 tablespoonssour cream
  • 1 tablespoonwhole-grain mustard
  • 1 tablespoonbutter
  • 3-4 medium leeks, washed and sliced into thin half moons
  • 1/2 cuproughly chopped kale
  • 2-3 strips bacon
  • 1 cupgrated Gruyere cheese (or sub another cheese like Cheddar)
  • 1 teaspoonfresh thyme
  • salt and pepper to taste
Directions
  1. To make the crust, preheat the oven to 350 degrees F.
  2. In a food processor, pulse together the oats, flour, and salt until the oats resemble flour. Add the oil and pulse a few times, then add the water, starting with the smallest amount (5 tablespoons), and adding more as needed until the dough comes together in a ball.
  3. Press the dough in a thin, even layer into a 9" tart or quiche pan with a removable bottom. (You can use a regular pie pan, but I find a tart pan to be easier for slicing the baked quiche.) Press the crust up the sides neatly.
  4. Bake the crust for about 10-12 minutes, or until just barely golden brown. Remove from the oven, turn the oven up to 375 degrees F, and let the crust cool while you make the filling. Alternatively, skip the blind baking step and just add the filling — this crust doesn’t require blind baking so it’s up to you!
  5. To make the filling, melt the butter in a large pan over medium-high heat. Add the leeks, season with salt and pepper, and cook, stirring occasionally, until the leeks soften. Towards the end of the cooking time, add the chopped kale and cook for another minute until the kale wilts.
  6. Chop the bacon into small pieces. In the same pan that you used for the leeks (don't wipe it out), cook over medium-high heat until crispy. Place the bacon onto a paper-towel lined plate and set aside.
  7. In a large bowl, whisk together the eggs, milk, mustard, and sour cream. Add the grated cheese, thyme, the cooked leeks and kale, and cooked bacon. Stir to combine.
  8. Carefully pour the filling into your prepared quiche crust. I like to place the crust on a baking sheet first and bake it this way, which makes it easier to take in and out of the oven and guards against spillage.
  9. Bake the quiche for 45-60 minutes; the quiche should be puffed and golden on the top and the eggs should feel just set all over. Remove from the oven and let cool for at least 15 minutes before slicing and serving.

The filling was amazing, but the crust was a mess. It absolutely needs baking and I nearly ruined my tart pan with it. The tart pan just spent a whole day soaking and still needed all the little flutes scrubbed out. Plus, it tasted very meh. I will make the filling again, but with a regular pie crust in a regular pie pan.

Really good! Now...I made this crustless as, based on other reviews, I was nervous about the crust. Didn’t miss it a bit. I used the 4 eggs called for but only 1 cup of milk (2%) and increased the gruyere to a cup and a half. I put this in a 9-inch deep dish pie pan and it worked great. Flavors and texture were super good and it was a hit with my family at brunch. Would definitely make again!

Crust was not an optimum texture did not hold together well the first time I did it, but I like the tastes assembled here, so I did it again. This time I added butter to the crust; I used same amounts of oats and flour and salt, with about three tbsp butter (pulsed first) and 3 tbsp oil (pulsed second) and only a couple tbsp water. Pressed in pan, blind baked for ten minutes and then cooled before filling. It was more substantial, held together well with the filling, good flavor, nice texture, and still pretty quick for a pie crust. Like others I cut the filling down (used 3 eggs and total 1.5 cups of dairy) and it was fine. Leftovers lovely for breakfast.

Delicious! Why not cook the bacon first, then the leeks in their grease?😋

Nice easy recipe for supper with salad. I used Trader Joe's frozen rolled crust, (takes an hour or so to thaw). If you use a 2" x 10" deep glass Pyrex pie plate the mixture is just the right quantity. Also used TJ's 3 pack of cleaned leeks and frozen spinach squeezed within an inch of its life. We enjoyed it and I will make it again. PS. if you use dry thyme be sure to half the quantity.

The filling was yummy and a huge hit even though I cheated and used a premade pie crust. As others have mentioned this is a whole lotta custard and I would cut the custard by half next time.

tldr: Filling is great, but the dough was problematic.

I made this last night. The filling is tasty! But I took other comments into account and only used 3 eggs, adjusting the milk accordingly. Even with only 3/4 of the original liquid, this made too much filling for a 9" pan. Furthermore, I was really disappointed by the crust. It was a strange combination of very dry and very pasty. There are much better crusts to be had, including a Patricia Wells press-in crust that also uses olive oil and water, but with much better results.

hi,does anyone know the amounts for the crust in weight?

AntoniaJames January 23, 2018

80 grams oats
120 grams flour
55 grams oil
good pinch of salt
75 - 90 grams / ml of water

Please, Posie, take the extra 30 - 60 seconds per recipe that is required to give us metric mass measures. ;o)

I'm looking forward to trying this. (As an aside, I've found brushing dijon mustard on the inside of a blind-baked crust, just after it comes out of the oven, helps with the crispness and adds a little flavor.)

MP C. January 21, 2018

Interesting! Will have to try that! Thanks for the tip!

I also found the filling to be too much, having used a conventional pie pan. I simply poured the extra in a muffin tin, for a quick breakfast this week! However, my concern is after prebaking the crust for 12 minutes, it was very wet after completing the recipe. Could it be because I used spinach in place of the kale? Should it be prebaked longer? Good, but was hoping for a crispier crust.

Made this quiche today. Wondering if the pan size should be larger than 9”. I used a Wilton 9” tart pan with removable bottom and the filling volume was too great to be accommodated in the tart. Baked the quiche using a portion of the filling and when baked and sliced I found the tart shell to be thick and tasting uncooked. Next time I’ll use a 10” pan. Good, but not what I expected.
