how to Thicken Pie Filling Without Cornstarch

So, let’s dive in and discover these ingenious ways to elevate your pies to the next level!

Arrowroot Powder

You can use arrowroot powder as a cornstarch alternative to thicken your pie filling. Arrowroot powder is derived from the arrowroot plant and is a great option for those who are looking for a gluten-free thickening agent.

It has a neutral taste and works well in both sweet and savory dishes. To use arrowroot powder, simply mix it with a small amount of cold liquid, such as water or milk, to create a slurry. Then, add the slurry to your pie filling and cook it over medium heat until it thickens to your desired consistency.

Arrowroot powder is a versatile thickener that can give your pie filling a smooth and glossy texture without altering the taste.

Tapioca Flour

Using tapioca flour is an effective alternative for thickening your pie filling. It works well because it has a strong thickening power and is gluten-free.

When you use tapioca flour, it forms a gel-like consistency that helps to bind the filling together and prevent it from becoming too runny. To use tapioca flour, simply mix it with your other dry ingredients before adding it to the filling. Be sure to follow the recipe instructions carefully to ensure the right amount of tapioca flour is used.

Remember that tapioca flour may take a little longer to thicken than cornstarch, so be patient and allow the filling to cook for a few minutes longer if needed.

Overall, tapioca flour is a great alternative for thickening your pie filling without using cornstarch.

Potato Starch

Potato starch is a suitable substitute for cornstarch when thickening your pie filling. It has a similar thickening power and can give your pie a smooth and glossy texture. To use potato starch, simply mix it with a small amount of cold water to create a slurry before adding it to your pie filling. Stir it well to ensure it is evenly distributed.

The starch will thicken the filling as it cooks, giving you a perfect consistency. Keep in mind that potato starch has a slightly different flavor compared to cornstarch, so it might alter the taste of your pie slightly. However, it is a great option for those who have corn allergies or prefer a gluten-free alternative.


Gelatin is a versatile ingredient that can be used in a variety of recipes to add texture and thickness. You can use gelatin to thicken your pie filling without cornstarch.

To do this, start by dissolving gelatin in a small amount of cold water. Then, heat up your pie filling on the stove and slowly add the dissolved gelatin mixture. Stir constantly to ensure that the gelatin is evenly distributed.

The gelatin will thicken the filling as it cools, giving you a deliciously rich and smooth texture. Just remember to use the appropriate amount of gelatin for the amount of filling you have, as too little may not thicken it enough, while too much may make it overly firm.

Fruit Pectin

Fruit pectin is a natural ingredient that can be used to achieve a thick and glossy texture in your pie fillings. It’s a great alternative to cornstarch if you’re looking for a more natural option.

To use fruit pectin, simply mix it with your fruit filling before baking. The pectin will act as a thickener, giving your pie a luscious consistency.

One advantage of using pectin is that it doesn’t alter the taste of your filling, allowing the natural flavors of the fruit to shine through. Additionally, fruit pectin sets quickly, so you won’t have to wait long for your pie to be ready to serve.

It’s an easy and effective way to achieve the perfect texture for your pies without the use of cornstarch.

Agar Agar

If you’re looking for a plant-based alternative to gelatin, agar agar is a great option. Agar agar is derived from seaweed and is commonly used as a gelling agent in various dishes.

To use agar agar as a thickening agent for your pie filling, simply dissolve it in hot water and then mix it into your fruit mixture. Agar agar sets at room temperature, so there’s no need to refrigerate your pie to achieve the desired consistency.

It has a neutral taste and doesn’t interfere with the flavors of your pie filling. Just make sure to follow the instructions on the agar agar package to get the right amount for your pie filling.

Enjoy your deliciously thickened pie!

Rice Flour

To achieve a gluten-free crust for your pie, rice flour is a great alternative. It not only provides a delicious taste but also helps in thickening your pie filling.

When using rice flour, you can simply substitute it for regular flour in your pie filling recipe. The rice flour will absorb the liquid in the filling and create a thick and luscious texture.

It is important to note that rice flour has a slightly different texture compared to regular flour, so you may need to adjust the amount used accordingly. Start by adding a small amount and gradually increase if needed.

Rice flour is a versatile option that will give you a gluten-free and perfectly thickened pie filling.

Almond Flour

You’ll love the nutty flavor and unique texture that almond flour adds to your gluten-free recipes.

Almond flour, made from finely ground almonds, is a versatile ingredient that can be used to thicken pie fillings without cornstarch. When mixed with fruits like apples or berries, almond flour helps absorb excess liquid and creates a deliciously thick filling.

It also adds a subtle nuttiness that enhances the overall flavor profile of your pie. To use almond flour as a thickener, simply mix it with your fruit filling and let it sit for a few minutes to allow the flour to absorb the juices.

The result? A perfectly thickened, gluten-free pie filling that will leave you craving for more.

Coconut Flour

Now let’s talk about another alternative to cornstarch for thickening your pie filling: coconut flour.

Coconut flour is a gluten-free option that can add a subtle tropical flavor to your desserts. To use coconut flour as a thickener, simply mix it with the fruit or liquid in your pie filling before baking. The flour will absorb the excess moisture, resulting in a thicker, more luscious filling.

Keep in mind that coconut flour absorbs liquid more than other thickeners, so you’ll need to adjust the amount accordingly. Start with a small amount and gradually add more as needed.

Coconut flour is a fantastic option for those who prefer a nutty and tropical twist in their pies. Give it a try and see how it elevates your next dessert creation!
