how to Thicken Peach Cobbler Without Cornstarch

Yes, you heard that right – no cornstarch needed!

Get ready to elevate your dessert game to a whole new level with these incredible techniques.

Let’s dive in and discover the secrets to the perfect peach cobbler!

Tapioca Starch

You can thicken your peach cobbler without using cornstarch by using tapioca starch instead. Tapioca starch is a great alternative that will give your cobbler a similar thick and gooey texture.

To use tapioca starch, simply mix it with your peach filling before baking. Start by combining the tapioca starch with some sugar and then sprinkle it over the sliced peaches. Gently toss the peaches to evenly coat them with the mixture.

As the cobbler bakes, the tapioca starch will absorb the excess moisture from the peaches, creating a thickened filling. The tapioca starch will also give a slight glossy sheen to the filling, making it even more visually appealing.

Arrowroot Powder

To thicken your peach cobbler without cornstarch, try using arrowroot powder instead. Arrowroot powder is a natural starch that works as a great alternative to cornstarch when it comes to thickening sauces and desserts. It is gluten-free and has a neutral taste, making it a perfect choice for those with dietary restrictions or preferences.

To use arrowroot powder, simply mix it with a small amount of cold water to create a slurry, then stir it into your peach filling before baking. The arrowroot powder will thicken the filling as it cooks, giving you a deliciously gooey and perfectly textured peach cobbler.

Potato Starch

Potato starch is a suitable alternative for thickening sauces and desserts when cornstarch is not available. You may be wondering why potato starch is a good substitute. Well, let me tell you.

Potato starch has similar thickening properties to cornstarch, so it can give your sauces and desserts that desired consistency. Plus, it is gluten-free, making it a great option for those with dietary restrictions.

To use potato starch as a thickener, simply mix it with a little bit of water to create a slurry, then add it to your sauce or dessert mixture. Be sure to cook it for a few minutes to activate the starch and thicken your dish.


Flour can be used as a versatile ingredient in baking and cooking due to its ability to provide structure and texture to a variety of dishes.

When it comes to thickening peach cobbler, flour is a great option. You can use all-purpose flour or even whole wheat flour if you prefer a heartier texture.

To thicken your peach cobbler, simply mix the flour with the peach filling to create a slurry. This will help absorb excess liquid and create a thick, luscious filling. Be sure to mix it well to avoid any lumps.

Once baked, the flour will work its magic and give your peach cobbler the perfect consistency.


If you’re looking for an alternative way to achieve a thickened texture in your dessert, gelatin can be a great option.

Gelatin is a protein-based ingredient that can be used to thicken various desserts, including peach cobbler. It works by forming a gel-like substance when mixed with liquid and cooled.

To use gelatin in your peach cobbler recipe, simply dissolve it in a small amount of warm water and then mix it into the filling before baking. As the cobbler bakes, the gelatin will set, creating a thick and luscious texture.

Gelatin is a versatile thickener that can be used in many other desserts as well, so it’s worth giving it a try if you’re looking for a different option than cornstarch.

Instant Tapioca

Tapioca can be a convenient thickening agent for desserts, such as fruit pies or puddings, due to its ability to create a gel-like consistency when cooked. When you use instant tapioca, you don’t have to worry about lumps or uneven thickening. It’s a quick and easy way to achieve the perfect texture in your peach cobbler.

Simply add the tapioca to the fruit filling, along with the other ingredients, and let it cook. The tapioca will absorb the excess liquid and create a thick, glossy sauce that coats the peaches beautifully. Plus, tapioca is flavorless, so it won’t alter the taste of your cobbler.

It’s a foolproof way to ensure your dessert turns out delicious every time.


One alternative thickening agent you can use in your fruit pies or puddings is pectin, which helps create a gel-like consistency when cooked. Pectin is a natural substance found in fruits, particularly in the peels and cores. It is commonly used in jams and jellies to help them set.

To use pectin as a thickener, you will need to look for a liquid or powdered form specifically designed for cooking purposes. Simply mix it with the fruit and other ingredients before cooking, and it will work its magic by forming a thick and luscious filling.

Pectin is a great option if you’re looking for a plant-based thickener that is also gluten-free. So, grab some pectin and get ready to enjoy a perfectly thickened fruit dessert!

Agar Agar

When using agar agar as a thickening agent, you can achieve a gel-like consistency in your desserts without using cornstarch or tapioca. Agar agar, derived from seaweed, is a natural and vegan alternative that has gained popularity in the culinary world.

To use agar agar, start by dissolving it in water and then bringing it to a boil. Once it boils, reduce the heat and let it simmer for a few minutes until the agar agar is fully dissolved. Then, add your desired fruit or juice and let it cook for a few more minutes until the mixture thickens.

The great thing about agar agar is that it sets at room temperature, so you don’t need to refrigerate your dessert for it to firm up. So, go ahead and experiment with agar agar to create deliciously thickened desserts without the need for cornstarch or tapioca.


Now that you know about using agar agar as a thickening agent for your peach cobbler, let’s talk about another option: clearjel.

Clearjel is a modified cornstarch that is specifically designed for canning and pie fillings. It’s a great alternative if you want to avoid using regular cornstarch.

To thicken your peach cobbler with clearjel, simply mix it with the peach filling before baking. Clearjel is heat resistant, so it will maintain its thickening properties even after being cooked. This means you won’t have to worry about your cobbler turning watery or runny.

Just like agar agar, clearjel is a versatile thickener that can be used in various recipes. It will give your peach cobbler a smooth and consistent texture without altering the taste.

Xanthan Gum

If you want to achieve a thick and smooth texture in your desserts, xanthan gum can be a great alternative to consider. It is a versatile ingredient that works well as a thickening agent in various recipes, including peach cobbler.

Xanthan gum is a natural polysaccharide that is made from fermenting corn sugar with a specific bacteria. When added to your dessert mixture, it helps to create a gel-like consistency and improve the overall texture.

Unlike cornstarch, xanthan gum doesn’t require heat to thicken, which makes it a convenient option for no-bake desserts or recipes that require minimal cooking time.

Just remember to use it sparingly, as a little goes a long way, and too much can result in a slimy texture.
