This traditional, lightly sweet gluten free custard pie with apples is made perfect for apple season with layers of thinly sliced apples. With or without a crust!
Why you'll love this gluten free custard pie with apples
A traditional egg custard is made with milk and eggs that are blended and baked. This custard pie is a cross between that sort of custard and cheesecake. Because who doesn't love cheesecake, and this one is only very lightly sweet, which makes it extra special before we even start talking about the apples.
You can make this pie with or without a crust, as it bakes up stable enough to be sliced crustless. But the light, flakiness of a bottom pie crust is the perfect contrast to the creaminess of the filling that's studded with fork-tender apple slices. So I highly recommend making it with the crust.
How to prepare and apples to the pie
Be sure to peel, core, and slice the apples thin, but not paper thin. If they're so thin they're practically see-through, they'll melt right into the custard as they bake.
The apples are settled into the filling in two layers, one in the middle and one on top. The top layer of apples browns a bit, thanks in part to a light drizzling of honey right before the pie goes into the oven. The middle layer of apples bakes just to fork tender and makes for an absolutely dreamy combination of textures.
Gluten free custard pie: Ingredients and Substitutions
As often as I can, I try to offer suggestions if you have other dietary preferences or restrictions. With some recipes, I'm a bit more optimistic than others.
I'm afraid with this custard pie with apples, as it relies quite heavily both on dairy and on eggs, I'm not too optimistic. But here are my best guesses:
Dairy-Free: First, for the crust: rather than using my recipe for extra flaky gluten free pie crust, which is made with butter and sour cream, I recommend using my recipe for traditional gluten free pie crust, and replacing the butter with butter-flavored Spectrum nonhydrogenated vegetable shortening.
The filling of this custard pie is made with both cream cheese and mascarpone cheese, and each presents a challenge to making this pie dairy free. I haven't tried to replace dairy in this pie, but you might experiment with dairy-free cream cheese as a replacement for both cheeses.
Egg-Free: As usual, my recommendation is that, for up to 2 eggs, a “chia egg” (1 tablespoon ground chia seeds + 1 tablespoon lukewarm water, mixed and allowed to gel) for each is usually a relatively safe bet.
But this recipe has very few ingredients, and it calls for 3 eggs. I'm afraid I don't feel confident about that replacement at all.
Flour: This recipe calls for 1 tiny tablespoon of tapioca starch/flour. You can also use my gum free gluten free flour blend in its place, or even 1 tablespoon of plain old cornstarch. It helps stabilize the filling as it bakes, especially as the apples release their moisture during baking.
Gluten Free Custard Pie With Apples
Ingredients
- 1 gluten free pie crust parbaked
- 2 large Granny Smith apples
- ½ cup (100 g) granulated sugar
- 1 teaspoon ground cinnamon
- 8 ounces cream cheese at room temperature
- 8 ounces mascarpone cheese at room temperature
- 3 (150 g (weighed out of shell)) eggs at room temperature
- 1 teaspoon pure vanilla extract
- ¼ teaspoon kosher salt
- 1 tablespoon (9 g) tapioca starch
- Honey for drizzling (optional)
Instructions
- Preheat your oven to 375°F.
Prepare the pie crust.
- Prepare the crust according to the recipe instructions, including parbaking the crust. Allow the crust to cool to room temperature.
Prepare the filling.
- Peel, core and slice the apples in half from end to end. Slice the apples thinly (about 1/8-inch thick, no thinner).
- In a medium-size bowl, place the sliced apples, 1/4 cup (50 g) of the granulated sugar, and the ground cinnamon and toss to coat the apples completely. Set the apples aside.
- In a large bowl or the bowl of a stand mixer fitted with the paddle attachment, place the cream cheese, mascarpone cheese, remaining 1/4 cup (50 g) sugar, salt, eggs, vanilla, and tapioca starch. Beat on medium speed until smooth and pourable.
Assemble the pie.
- Pour about half of the filling into the prepared pie crust and smooth into an even layer.
- Arrange the apple slices on top of the filling in a single layer, top with the remaining filling, and finish with another single layer of apple slices.
- Drizzle the apples on top of the filling with about 1 tablespoon of the (optional) honey in an even layer.
Bake the pie.
- Place the pie in the center of the preheated oven and bake for about 35 minutes, or until the custard is set and doesn’t jiggle when the pan is moved from side to side.
- It will be mostly firm to the touch in the center, and the filling will be puffed.
Cool and chill the pie.
- Remove the pie from the oven and allow it to cool to room temperature before placing in the refrigerator to chill until firm (about 3 hours).
- Allow the pie to sit at room temperature for about 10 minutes before slicing and serving.

Hi, I’m Nicole. I create gluten free recipes that really work and taste as good as you remember. No more making separate meals when someone is GF, or buying packaged foods that aren’t good enough to justify the price. At Gluten Free on a Shoestring, “good, for gluten free” just isn’t good enough! Come visit my bio!

Thanks Nicole,
I love your cookbooks and the blog. The pie, without the crust tastes AWESOME! It’s like cheesecake, but not so dense. The texture is really great. I do not have a regular non-stick pie pan, and so I just did a little butter in a normal one for the no crust pie. It is a bit sticky, so I’d suggest a bit extra on the lubrication or the spring form if you don’t have non-stick. If I’d had a heavier hand with the butter I think it would have been fine in my pan.
But to repeat, the taste is awesome. We are more traditional plain fruit with our crusted pies, so I don’t think we’ll take this that way, but I’m trying to calculate what else I can put in the crustless. I’m all about the peaches we are still getting at the farmer’s market, although liquid balance could be an issue with them and more so with the berries I’m thinking about trying – maybe a light dust with tapioca starch for the berries? I really think bananas would go right in and be awesome, maybe with a light granola topping in place of the crust – banana pudding, but so much tastier. Thank you so much for this recipe! Every time I take a bite more ideas pop into my head.

What if you don’t have a stand mixer?
Nicole Hunn says
You can use a hand mixer to mix the filling, like I did in the video, Randy!

This looks awesome, and easy with the crust. Sometimes I do want to not bother with a crust and the custard seems to be a better match for that than most. I’m wondering about a crustless pie. Do I bake for the same time. It seems a tart or springform pan would be the way to go there rather than a regular pie pan. Do you have suggestions for the best way to do crustless?
Nicole Hunn says
You do bake it for the same amount of time, Martha, yes. You don’t need a springform pan or tart pan. A regular pie pan will do. I hope that helps!
