Keto Pumpkin Pie

I’ve made a lot of pumpkin desserts over the years (there’s a whole collection on this site), but this is the one I come back to every single November. It started as an experiment back when I was still tweaking crust recipes, and after testing multiple versions, I landed on a flaky keto pie crust that actually behaves like traditional pastry. Cold butter, minimal handling, and an hour in the fridge before rolling. That’s the secret to getting real flaky layers instead of a crumbly cookie-textured base.

I originally used a different crust for this recipe (you might see it in the older video) that called for arrowroot powder. I’ve since rewritten the crust entirely to use xanthan gum instead, and the result is so much better. It rolls out thinner, holds its shape in the oven, and doesn’t have that starchy aftertaste. This is the version I’ve been making for the last few years, and it’s the only one I’d recommend.

Most recipes I’ve seen bake their filling at 350 or even 375. I go lower, 325 degrees for 50-60 minutes, because pumpkin filling is essentially a custard. Higher heat sets the edges too fast while the center is still liquid, and that’s how you get cracks. My way takes a little longer, but the filling sets evenly from edge to center with a smooth, creamy top.

The filling itself is just pumpkin puree, heavy cream, eggs, and spices. I use golden monk fruit to sweeten it, and I add a splash of bourbon (optional, but I always include it). The ginger and cinnamon come through without tasting like a spice rack exploded. My family doesn’t do keto, and they eat this alongside the regular pumpkin pie at Thanksgiving. They can’t tell the difference, which is the whole point.

If you want something faster, I have crustless keto pumpkin pies that skip the crust entirely and bake in a muffin tin. Or if you’re cooking for one, the single serve version scales everything down. For more pumpkin season baking, my keto pumpkin roll is another one I make every fall.

This is my go-to low carb holiday dessert for making ahead. I’ve kept it in the fridge for up to four days and it actually tastes better on day two once the spices have had time to meld into the filling. It holds its shape cleanly when you slice it cold. Bring it to room temperature for about 20 minutes before serving if you like it less firm, or serve it straight from the fridge with a dollop of whipped cream.

The crust is the part that intimidates most people, but I’ve made it enough times to know exactly where things go wrong. Keep your butter cold. If it starts softening while you’re pulsing, put everything back in the fridge for 10 minutes. You want visible chunks of butter in the dough, because those chunks create steam in the oven and give you flaky layers. If you overwork it, you’ll get a crust that tastes fine but has more of a cookie texture.

For the filling, I use what I call the wobble test. At around 50 minutes, open the oven and give the pan a gentle nudge. The center should jiggle like set Jello, not slosh like liquid. The edges will look firm and the very center will have a slight movement. It keeps setting as it cools, so pulling it out at that stage gives you a creamy slice once it’s chilled. If you’ve ever overbaked a custard and gotten that rubbery skin on top, this is how you avoid it.

One more thing: I bake at 325, not 350 like most keto pie recipes. The lower temperature is slower but gives the filling time to set evenly without the edges cooking too fast. I use the same approach for my keto apple pie and it works every time.
