Lemon Buttermilk Custard Pie

There are a lot of desserts that I enjoy eating, but anything that’s lemon flavored has a special place in my heart. And this Lemon Buttermilk Custard Pie was my introduction to the awesomeness of lemon desserts.

I’m a huge fan of lemon desserts. I also love custards. If you’re like me, you’ll love this one! It’s nice and light, creamy, and tangy, and a fool-proof recipe. ⠀

I used to make this years ago back in culinary school, and my little sister has been bugging me to make it for her since then. After doing some organizing at home, I recently found all of my recipes from college, (finally) made this for her, and now she’s the happiest person in the world! Fingers crossed she stops bugging me about it. Probably not though since it is delicious.

I am NOT good at baking! So you can handle this one!

I am not a fan of measuring stuff and making sure things are a certain temperature to be blended correctly. So, for those of you that don’t like to bake but love to eat baked products, this is an extremely easy recipe for you to follow! Like, too damn easy. So easy that it can be done with your eyes closed if you wanna be that rebellious.

How I got my pie the consistency of a custard without cooking it ahead of time:

To bake, the oven is preheated at a high temperature, then turned down once the pie is placed in the oven. This makes the top half of the pie completely set, like a really soft cake. But as you get near the bottom half, it’s like the texture of lemon curd. And when it’s mixed together it’s magical!!!!

Can the serving size for this recipe be modified in any way?

I also love how light this dessert is. This recipe can be made into 2 thinner pies which sounds like a lot, but is perfect if you’re looking to feed a crowd.

What garnishes should I use for the lemon pie?

Serve this with a dollop of whipped cream to add another layer of creamy-ness and you have a nice refreshing dessert. Or breakfast if you’re like me.

Lemon Buttermilk Custard Pie

Prep Time10 minutes
Cook Time50 minutes
Rest Time2 hours
Total Time3 hours
Course: Dessert
Cuisine: American
Keyword: lemon, pie
Servings: 8 slices
Author: Crystal

Equipment

  • Large bowl
  • Hand mixer
  • Zester

Ingredients

  • 1 ¼ cup granulated sugar
  • 3 tbsp all purpose flour
  • ¼ teaspoon ground nutmeg
  • ½ cup unsalted butter melted
  • 3 eggs
  • 8 ounces buttermilk
  • 2 tbsp lemon juice
  • zest of a lemon
  • 1 9 inch deep dish pie crust frozen and unbaked

Instructions

  • Preheat oven to 400 degrees.
  • In a medium sized bowl or mixer, mix together the sugar, flour, and nutmeg on the lowest speed.
  • Pour in butter and mix together.
  • Add the eggs and thoroughly mix in, one at a time.
  • Slowly pour in the buttermilk while mixing. Add in the lemon juice and zest, blending for 30 seconds. Scrape down the insides of the bowl for any unmixed batter. Blend for an additional 30 seconds.
  • Evenly pour the mixture into the unbaked pie shells.
  • Put the pies into the oven, and set a timer for 50 minutes. Once the timer is set, turn the oven down to 325 degrees.
  • Once baked, let cool to room temperature before refrigerating.

Notes

Keep the filled pie crust on a pan wider than the side of the pie shell.  This will make it easier to place the pie into the oven, as well as removing it from the oven.
The recipe can be made into 2 smaller pies to yield more servings. Use 2 regular sized 9 inch pie crusts instead of one deep dish pie crust. Split the pie mixture between both pie crusts and bake for 25 minutes.

    This pie was so delicious. The crust was flaky and the lemon filling was fresh. I plan to serve this as dessert next weekend for my family.

    I’m obsessed with lemon desserts and even more obsessed with this pie. I made it and brought it to a friends house for a small brunch gathering and everyone loved it! I almost regretted not keeping the whole thing for myself because it was so good… but they were definitely impressed by my efforts, thanks to you!

    I’ve made lemon buttermilk pie before and what set your pie apart and made it better was starting off on high heat. Such an invaluable tip. Thank you so much.

    As soon as I read this pie combined buttermilk and lemons, I knew it would be good – and frankly it exceeded all exceptions.

    You say you’re not a baker, but after tasting this lemon buttermilk custard pie, I have a hard time believing that. It had just the right amount of pucker balanced with sweet. We loved it.
