Creamy Keto Pumpkin Pie with a Buttery Almond Crust
This keto pumpkin pie brings back everything you miss about the classic holiday dessert: a smooth, spiced custard and a flaky crust that doesn’t taste like cardboard. No one will guess it’s low-carb.
You can make it a day ahead, which means less stress on the big day. It slices beautifully and holds its shape just like a traditional pie.
What Makes This Keto Pie Work
I stopped hunting for a good keto pumpkin pie the day this one landed. The almond flour crust stays crisp and nutty, never oily or crumbly like the first few versions I tried.
The filling is silky and dense without a trace of grittiness, because the sweetener dissolves completely into the pumpkin. It’s a pie you can serve to anyone at the table, keto or not.
Ingredients
- 1 ½ cups super-fine blanched almond flour: gives the crust structure; do not substitute almond meal
- 6 tbsp unsalted butter, cold and cubed: you can use solid coconut oil for dairy-free
- ¼ cup granulated erythritol or monk fruit sweetener: a fine grind works best here, with no cooling aftertaste
- ½ tsp salt
- 1 (15-oz) can 100% pumpkin puree: not pumpkin pie filling, which is full of sugar
- 1 cup heavy cream: coconut cream works if you need it dairy-free
- 3 large eggs, room temperature
- ⅔ cup powdered erythritol or monk fruit sweetener: a powdered sweetener melts into the custard effortlessly
- 1 ½ tsp pumpkin pie spice
- 1 tsp vanilla extract
Variations and Substitutions
- Dairy-free: use cold coconut oil for the crust and full-fat canned coconut cream instead of heavy cream. The filling will still set firmly.
- Sweetener: golden monk fruit blend adds a subtle caramel note. If you only have granulated sweetener, just grind it into a powder first.
- Spice: if you don’t have pumpkin pie spice, mix 1 tsp cinnamon, ¼ tsp ginger, ¼ tsp nutmeg, and a pinch of cloves. Freshly grated nutmeg makes a difference.
- Pecan topping: chop ⅓ cup pecans, toss with a little melted butter and sweetener, and scatter over the pie halfway through baking for a crunchy finish.

How to Make Keto Pumpkin Pie
Step 1: Mix the Crust Dough
Preheat your oven to 350°F (175°C). In a bowl, combine the 1 ½ cups almond flour, ¼ cup granulated sweetener, and ½ tsp salt. Add the cold cubed butter and use a pastry cutter or your fingertips to work it in until the mixture looks like coarse crumbs and just holds together when you pinch it.
You’ll see streaks of butter throughout. That’s good, it’s what makes the crust tender. The dough won’t be smooth like a traditional wheat pastry.
Trust the crumbly texture. Pressing it into the pan will bring everything together, so don’t keep cutting the butter. Overworking almond flour can release its natural oils and make the crust greasy.
Step 2: Blind-Bake the Crust
Tip the crumbly dough into a 9-inch pie dish and press it evenly across the bottom and up the sides. Use your fingers or the bottom of a measuring cup to compact it firmly. Prick the bottom a few times with a fork to let steam escape.
Line the crust with parchment paper and fill it with pie weights or dried beans. Bake for 10 minutes, then remove the parchment and weights. The dough will look dry on the surface but not yet golden.
Return the crust to the oven and bake another 5 to 7 minutes, until the edges just start to turn light brown and the bottom feels set to the touch. Blind-baking like this keeps the filling from making the crust soggy, because almond flour absorbs moisture quickly if it hasn’t been baked first.
Step 3: Whisk the Pumpkin Filling
In a large bowl, whisk the 3 eggs until they’re frothy. Add the 15-oz can of pumpkin puree, 1 cup heavy cream, ⅔ cup powdered sweetener, 1 ½ tsp pumpkin pie spice, and 1 tsp vanilla. Whisk until the mixture is completely smooth, about 30 seconds.
You’re looking for a thick, pourable batter that moves like a heavy custard. If you see streaks of egg white, keep whisking a few more beats.
Stop whisking as soon as it comes together. Overbeating the eggs introduces air bubbles that can rise to the surface and crack during baking. A gentle mix gives the creamiest finish.
Step 4: Bake the Pie
Pour the filling into the warm blind-baked crust. Give the pie dish a light jiggle to settle any air pockets. Bake at 350°F (175°C) for 40 to 50 minutes, checking at the 35-minute mark. If the crust edges are browning too fast, cover them loosely with strips of foil or a silicone pie shield.
The pie is done when the outer inch rings look set and the center still wobbles slightly when you nudge the dish. Don’t wait until the center is firm, or you’ll overbake it.
Overbaking is the main reason pumpkin pie cracks. The residual heat will continue cooking the custard as it cools, so pulling it while the center jiggles guarantees a smooth top later.
Step 5: Cool and Slice the Pie
Remove the pie from the oven and set it on a wire rack to cool completely at room temperature, about 2 hours. Once it’s no longer warm, transfer it to the fridge and chill for at least 2 hours, or overnight if you can.
You’ll see the custard firms up to a velvety sliceable texture after chilling. The almond crust will have darkened to a rich golden brown.
When you’re ready, run a knife under hot water, wipe it dry, and slice cleanly through the pie. Serve each wedge with a dollop of unsweetened whipped cream right away.
Tips for a Spot-On Keto Pie
- Use plain pumpkin puree, not pie filling. Canned pumpkin pie mix is already sweetened and seasoned, and it will throw off the carb count and texture.
- Shield the crust edges early. Even a few minutes of direct heat can darken almond flour too much. A reusable silicone shield or foil strips help the crust stay golden, not burnt.
- Grind your sweetener if it’s granular. A powdered sweetener blends in seamlessly with no crunchy bits in the filling. If yours is coarse, blitz it in a blender for a few seconds.
- Chill overnight for the cleanest slices. A long chill sets the custard completely and brings the spice flavors forward. A 2-hour chill works, but 8 hours is even better.
- Cool gradually to avoid cracks. Don’t move the pie straight from the oven to the fridge. Let it come to room temperature first so the custard doesn’t contract too fast.
Keeping Leftover Pie Fresh
- Refrigerate: Cover the pie loosely with plastic wrap or store slices in an airtight container. It keeps well for up to 4 days.
- Serve cold: This pie tastes best straight from the fridge, so there’s no need to reheat it. The custard stays dense and the crust stays crisp.
What to Serve with Keto Pumpkin Pie
A generous spoonful of lightly sweetened whipped cream cuts through the richness and adds a cool contrast. A cup of dark roast coffee or a chai latte also balances the warm spice notes. For an extra treat, drop a small scoop of keto vanilla ice cream on the plate.
Frequently Asked Questions
Is pumpkin actually keto-friendly?
Yes, in moderation. A half cup of plain pumpkin puree has about 10 grams of net carbs, but each slice of this pie uses far less, so it fits into a low-carb day without trouble.
Can I use coconut flour instead of almond flour?
No, the crust won’t hold together properly. Coconut flour behaves differently and would need more liquid and eggs to work, which would change the pastry completely.
Can I make this pie dairy-free?
Yes. Replace the butter with cold solid coconut oil and use full-fat canned coconut cream in place of the heavy cream. The texture will be slightly denser but still delicious.
Why did my filling crack?
Usually the pie was overbaked or cooled too quickly. Pull it from the oven while the center still jiggles, and let it cool gradually on the counter before refrigerating.
