Buttermilk Apple Custard Pie Recipe

This pie is the kind of thing that sneaks up on you: a flaky crust, thinly spiced apple slices, and a soft, tangy buttermilk custard that sets into something silky but not overly sweet. It’s autumn in a pan but honestly good any time you want a dessert that feels homemade and not too precious. It slices clean-ish, jiggles a little, and makes people linger over the coffee afterward.

My husband calls this “the pie that makes him text his mom.” True story. It started as a pandemic experiment — I had too many apples and a half-sour carton of buttermilk, and I threw them together because logic and stubbornness told me it would work. Now it’s our weekend staple: he walks in, smells it, and immediately disappears into the backyard pretending to fix a fence while really just waiting for the oven timer. The kids? They fight over the end crust like vultures. This one lives on rotation because it’s forgiving, kind of elegant, and always feels like an event even if I pulled the crust from the freezer.

I once tried slicing the apples paper-thin with a hand grater because the mandoline was “too loud.” Don’t do that. You’ll end up with apple shavings that melt away into sadness. Also, I’ve swapped white sugar for maple syrup in a last-minute panic and it added a smoky depth that actually worked — but only if you like the maple to sing. Oh, and don’t skip chilling the crust briefly; it’s the difference between glassy flake and sad dough. Other than that, this pie tolerates a messy kitchen and a soundtrack of whatever podcast you forgot you were listening to.

Shopping Tips

– Fruit: Choose crisp, slightly tart apples like Granny Smith, Honeycrisp, or Pink Lady so the apples hold their shape and balance the custard.
– Baking Basics (Flour/Sugar/Leaveners): Use all-purpose flour for the crust and a mix of granulated and brown sugar for the filling if you like a deeper caramel note.
– Dairy: Real buttermilk is best for that tangy custard; if you’re buying a carton, check the sell-by and pick the freshest.
– Eggs: Room-temperature eggs help the custard come together smoothly; if you forget, pop them in warm water for a few minutes.
– Fats & Oils: Use a good-tasting butter for the crust — it shows. If you must use shortening, mix half butter/half shortening for better flavor and flake.

Prep Ahead Ideas

– Slice the apples a day ahead and toss them with a little lemon juice and sugar; store in an airtight container in the fridge so they’re ready to pile into crust.
– Blind-bake or par-bake the crust and keep it covered on the counter for up to a day, then pour in custard and bake the next day.
– Mix the custard base (eggs, sugar, buttermilk, vanilla, spices) the night before, cover tightly, and keep chilled; give it a quick whisk before pouring.

✔Time-Saving Tricks

– Use store-bought pie dough if your hands are tired; press and patch like you mean it — no one will know.
– Slice apples with a mandoline or food processor attachment to save time and get consistent thickness.
– If you’re impatient, bake at a slightly higher temp for the first 10 minutes to set the crust, then lower to finish the custard; just watch so it doesn’t brown too fast.

✔Common Mistakes

– Overbaking the custard: it should still jiggle slightly in the center when you pull it out; carryover heat will finish it. I once left mine until rock-solid and had to serve it under a scoop of whipped cream to hide my crime.
– Soggy bottom: make sure the crust is cold and consider a quick brush of beaten egg or a thin blind-bake to form a barrier.
– Apples too thick or too thin: too-thick slices don’t cook through; too-thin ones disappear. Aim for about 1/8–1/4-inch slices depending on the apple.

What to Serve It With

– A big scoop of vanilla ice cream or a dollop of unsweetened whipped cream.
– Simple bitter greens tossed with lemon and olive oil to cut the richness.
– A hot mug of coffee or black tea for afternoon dessert.
– Short, sweet: toasted pecans or a drizzle of maple syrup if you want extra drama.

✔Tips & Mistakes

– Let the custard rest a little before slicing — it firms up and slices cleaner.
– If you see the edges browning too fast, tent with foil.
– Salt the crust dough lightly; it makes a huge difference in flavor.
– Forgot to chill the crust? Pop it in the freezer for 10–15 minutes before baking.

✔Storage Tips

Store leftovers covered in the fridge for up to 3 days. Cold slices are fine for breakfast (no judgment here), but allow them to come to room temp or warm gently for best texture. Freezing whole pies isn’t ideal for custard texture, but you can freeze individual slices wrapped tightly — thaw in the fridge overnight.

✔Variations and Substitutions

– Swap buttermilk for plain yogurt thinned with a little milk if you’re out; it keeps that tangy note.
– Use pears instead of apples for a softer, sweeter pie — reduce any added sugar slightly.
– Add a splash of bourbon or a teaspoon of espresso powder to the custard for grown-up depth.
– For nut lovers, scatter toasted walnuts or pecans on top before serving for crunch.

Main Ingredients

• ▢ 10 oz refrigerated pie dough, for a 9-inch pie plate chilled
• ▢ 1.25 lb firm baking apples, peeled and thinly sliced such as Honeycrisp or Granny Smith
• ▢ 1 tbsp lemon juice
• ▢ 0.75 cup granulated sugar
• ▢ 2 tbsp light brown sugar packed
• ▢ 3 tbsp all-purpose flour
• ▢ 1 tsp ground cinnamon
• ▢ 0.25 tsp ground nutmeg
• ▢ 0.25 tsp kosher salt
• ▢ 5 fl oz beaten eggs about 3 large
• ▢ 1 cup buttermilk well-shaken
• ▢ 4 tbsp unsalted butter melted, divided
• ▢ 1.5 tsp vanilla extract
• ▢ 1 tbsp coarse sugar for topping

Instructions

Preparation Steps

• Heat oven to 375°F with a rack in the lower third. Place a sheet pan on the rack to preheat.
• Fit the chilled dough into a 9-inch pie plate, crimp the edge, and refrigerate while you prepare the filling.
• Toss sliced apples with lemon juice, 2 tablespoons of the granulated sugar, and half the cinnamon.
• Warm 1 tablespoon melted butter in a skillet over medium heat. Cook apples 4–5 minutes until slightly tender. Cool 5 minutes.
• Whisk remaining granulated sugar, brown sugar, flour, remaining cinnamon, nutmeg, and salt in a bowl.
• Whisk in beaten eggs, buttermilk, vanilla, and the remaining 3 tablespoons melted butter until smooth.
• Spread apples in the crust. Sprinkle coarse sugar over apples, then pour the custard on top. Tap the pan to settle.
• Bake on the preheated sheet pan 50–55 minutes, tenting the edge if browning quickly, until the center quivers slightly.
• Cool on a rack at least 2 hours. For clean slices, chill 1 hour before serving.

Notes

Variation: Swap 1 tsp vanilla for 1 tbsp bourbon or apple brandy for a spirited finish. For extra crunch, sprinkle 2 tbsp chopped pecans over the apples before pouring in the custard. Store leftovers covered in the fridge up to 3 days; rewarm slices briefly at 300°F.
