If you are needing some new quiche ideas, this bacon, leek and buttermilk pie is made in an oatmeal crust. That sturdy crust is then sprinkled with crisp bacon, topped with a lot of chopped leeks and covered in a cheese, buttermilk and mustard custard. What's not to like?
This bacon quiche with leeks and buttermilk is an Irish pie that should be what's for dinner or brunch.
And pie or quiche? Real men don't care. But hopefully this hearty Irish pie will give you more quiche ideas!
This bacon, buttermilk and leek Irish pie recipe is a new one for me.
No heavy cream, no half and half. Just buttermilk, which makes it savory and tangy and light.
It does taste deliciously of bacon and cheese.
Cooking with leeks is so easy. They don't even need to be sauteed.
And don't forgot mustard. I love mustard and mustard is awesome with leeks. And bacon. And cheese.
I can't imagine what it is about St. Patrick's Day that makes me think green.
And so it is I found this Irish dish and myself with a pile of green monster leeks that were absolutely gorgeous.
Needing something to do with them, and not wanting soup, my tired brain decided pie. I have no idea why-but pie they became.

Don't forget the oatmeal crust. It is a very sturdy crust which is very necessary to hold the leeks.
And though there are a lot of leeks, don't think this tastes too oniony. Because it doesn't.
It just tastes good. And filling. If you don't have time to make the crust, just buy one. Because today I'm all about easy.
What did I serve with this bacon, leek and buttermilk pie?
I roasted some cabbage wedges to serve on the side. And some teeny roasted red potatoes would be great, too.
You know the baby ones. Sprinkled with a little sea salt. You could even brush them with bacon grease, like I did the cabbage.
And if you really wanted too, you could sub out the bacon for corned beef; but I'm a pretty big lover of bacon.
And I'm a pretty big lover of this savoury tart with bacon, leeks and buttermilk!

Description
This bacon, leek and buttermilk Irish pie in an oatmeal crust is savory and satisfying. Plus it's a great way to use up buttermilk and enjoy leeks.
Ingredients
Oatmeal Crust
¼ c Irish oatmeal
½ c wholewheat flour
½ c plus 2 T all purpose flour
1 t salt
5 T butter
3 oz Dubliner Irish Cheese, shredded
3 T water or Guinness
Ingredients for Filling:
8 slices of thick bacon, cooked crisp or use 1-2 c of shredded corned beef
About 3-4 c of sliced leeks or enough to fill your crust
4 eggs
1 ¾ c buttermilk
4 oz Dubliner Irish Cheese, shredded
1 T wholegrain mustard
Pinch of cayenne pepper
Instructions
Directions for crust:
Lightly grease a 9 or 10" pie pan. In a food processor, combine oatmeal, both flours, salt, butter and grated cheese. Process until the mixture resembles bread crumbs. Add the water or beer (who are we kidding here?) and mix to form a dough. It should start to form a ball. Denver is dry so I had to add a bit more beer. Use your judgment, just save some for the crust! Chill, wrapped in wax paper for up to 30 minutes.
Preheat oven to 350.
Turn the dough onto a lightly floured surface and roll out to a 12" diameter. This is a heavy dough-not flaky! Transfer to pie plate and make beautiful. You can see I'm really good at that! Prick crust with a fork, line with foil and pie weights or dried beans. Bake about 12 minutes and remove.
Directions for Filling:
Crumble the crisply cooked bacon. Spread bacon on bottom of crust.
Top bacon with the chopped leeks.
In a large bowl, combine the eggs, buttermilk, cheese, mustard and cayenne. Beat well. Pour filling over bacon and leeks. Bake for about 45 minutes or until the top starts to brown and filling is set.
How easy was that?
Notes
Recipe from Irish Abroad
Chef Mimi says
this is so different - I love it! The crust, the buttermilk… a great recipe.
ChgoJohn says
I must admit, Abbe, that leek and buttermilk are nice touches. Still, you had me when I saw "bacon" and "pie" in the title. I'm a simple man, you see. If it's got bacon, I am sooo there.
PS It's the same with pasta, in case you're keeping track. 😀
Sippity Sup says
I'm back in Los Angeles from Nicaragua and heading to Florida tomorrow. I'm spending my one morning home to catch up on my favorite blogs. Thanks for the pie. I will feel nourished in my journeys. GREG
PS I too prefer the name pie for this beauty.
Abbe Odenwalder says
Thanks, my friend! Have a great holiday-like you haven't already!
Katerina says
What a luscious rich in flavor pie! Popping up from culinaryflavors.gr.
Abbe Odenwalder says
Thanks Katerina and thanks for stopping by!
SavoringTime in the Kitchen says
This looks so good, Abbe! I love the sound of the oatmeal crust and leeks are a favorite. I still have some KerryGold cheddar in the frig from my St. Patrick's Day recipe so I know what I'm making soon 🙂
Allie | In This Kitchen says
Wow, this sounds seriously good. Pinning it for later because my boyfriend and I will devour this thing!
Karen Harris says
I'm so sorry I've been MIA these past few days and haven't told you how delicious this recipe looks! Perfect for when you're feeling a bit Irish.
Bam's Kitchen says
Sounds blissful Abbe. Loving those flavor combinations. I think a quiche can be served at any time of the day and would be good and heck my boys would polish off one pie as a snack. Is your son still living in China? How is he doing? Living so far away is difficult...I know.
Karen (Back Road Journal) says
This is such a different and delicious sounding pie. Even though I missed it for St. Patrick's day, it doesn't mean that I'll wait a year to make it.
Libby Weiner says
I'm going to break down and bake. This pie/quiche sounds really spectacular. Thanks Abbe.
Agness Walewinder says
Bacon combined with leek? Never tried it, but it seems and looks extremely yummy! 🙂 Perfect dinner idea! 🙂
Abbe Odenwalder says
Bacon and leeks should be married. They go together so well!
Marcie Flavor the Moments says
This is such a wonderful Irish pie full of so many delicious ingredients! I love the sound of that crust, and leeks are something that I can never get enough of. This looks amazing!

Thanks Marcie! This is a keeper!

it was new for me also, Tandy. And I will do it again!

Love savoury pies, too!

What a great combination of flavors, Abbe. savory, rich, creamy with a hint of kick. Delicious!

I bet your wolfing down a few slices of this RIGHT NOW!
Abbe Odenwalder says
Well. there are a few left in the fridge!
Holly @ abakershouse.com says
I would eat this morning, noon or night. I am especially curious about the oat crust. Looks great!
Abbe Odenwalder says
It is a very sturdy crust. Thick and pliable. Thanks Holly!
La Table De Nana says
Irish oatmeal..never heard of such a thing..however this looks great!
Abbe Odenwalder says
Steel cut oats-I should have specified that, but both types work! Thanks Monique!
Tricia Buice says
I wholeheartedly agree with everything you wrote - and leeks, and bacon, and cheese and mustard - well they are MFEO (made for each other) - looks and sounds delicious! Happy St. Patrick's Day!
Abbe Odenwalder says
MFEO-like that Tricia!
Liz Berg says
Now this is a delicious way to celebrate St. Patty's Day. Bill doesn't like corned beef (sigh), but bacon is a whole different story! I love a quiche any time of day 🙂
Abbe Odenwalder says
I like corned beef, but only on a sandwich. An now that I don't eat beef, I don't even get that! So just give Bill the bacon!
Denise Browning says
What a pie! Full of the great stuff... please, invite me for dinner.
Abbe Odenwalder says
Any time you are near here, Denise. It would be my pleasure!
Kitchen Riffs says
Pie is always good. Quiche too. And buttermilk in quiche? Haven't had that, but do like the idea. That tangy part, you know. Really nice -- thanks.
Abbe Odenwalder says
The buttermilk worked great and saves a lot of calories, too! Thanks John!
Cheri Savory Spoon says
Hi Abbe, you are on a roll, this looks amazing. I could enjoy this anytime of the year, any season. I love what leeks do to a dish, so much flavor.
Abbe Odenwalder says
I don't use leeks enough and they are so good! Thanks Cheri!
Lea Ann (Cooking On The Ranch) says
Bacon, oatmeal crust and Dubliner cheese! I'm in. Sounds great leeks and all. I'm voting for calling this a pie, quiche is too fancy French for this hearty dish. Pinned.
Abbe Odenwalder says
Good point, Lea Ann!
