Yes, you can substitute coconut flour for cornstarch, but it won’t be a straight one-for-one swap.
Coconut flour is much thirstier than cornstarch, so you’ll need to use less of it and add extra liquid to whatever you’re cooking.
If you’ve been wondering whether you can substitute coconut flour for cornstarch in your recipes, the short answer is yes, with some adjustments.
It works best as a thickening agent in soups, stews, and gravies, though the texture will be slightly different from what cornstarch gives you.
In this post, we’ll look at how to substitute coconut flour for cornstarch, the right ratios to use, and when this swap works and when it doesn’t.
Let’s dig in.
Can You Substitute Coconut Flour for Cornstarch?
You can substitute coconut flour for cornstarch, and here’s why it works:
1. Both Are Thickening Agents
Cornstarch is a classic thickener, and coconut flour can do the same job because it absorbs a lot of liquid.
When you substitute coconut flour for cornstarch in a sauce or stew, the flour swells and traps liquid, which thickens the mixture.
It’s not identical to cornstarch, but it gets the job done in many recipes.
2. Coconut Flour Is gluten-Free
If you’re cooking gluten-free, coconut flour is a great stand-in for cornstarch since both are naturally gluten-free.
So when you substitute coconut flour for cornstarch, you’re not adding any gluten to your dish.
That makes it a safe swap for anyone with celiac disease or gluten sensitivity.
3. It Adds a Subtle Coconut Flavor
One thing to keep in mind is that coconut flour brings a mild coconut taste.
In savory dishes like stews, you might not notice it, but in lighter recipes, it can come through.
If you plan to substitute coconut flour for cornstarch in a delicate sauce, taste as you go to make sure the flavor works.
How to Substitute Coconut Flour for Cornstarch
Getting the ratio right is the key to making this swap work.
Here’s how to substitute coconut flour for cornstarch properly:
1. Use Less Coconut Flour
Coconut flour absorbs far more liquid than cornstarch, so you can’t use the same amount.
As a rule, use about half the amount of coconut flour that the recipe calls for in cornstarch.
So if a recipe needs two tablespoons of cornstarch, start with one tablespoon of coconut flour.
2. Add Extra Liquid
Because coconut flour soaks up so much moisture, you’ll likely need to add more liquid to keep the consistency right.
Add a splash of water, broth, or milk and stir well before deciding if you need more.
This step matters most when you substitute coconut flour for cornstarch in thicker dishes like gravies.
3. Whisk It In Gradually
Coconut flour tends to clump, so whisk it into a small amount of cold liquid first.
Then pour that slurry into your hot dish and stir constantly.
This keeps your sauce smooth when you substitute coconut flour for cornstarch.
4. Cook a Little Longer
Coconut flour needs a few extra minutes to fully thicken compared to cornstarch.
Give your dish a gentle simmer and stir occasionally so the flour can do its job.
When Substituting Coconut Flour for Cornstarch Works Best
This swap isn’t perfect for every recipe, so here’s where it shines:
1. Soups and Stews
Hearty dishes are the easiest place to substitute coconut flour for cornstarch.
The bold flavors mask the coconut taste, and the extra liquid is easy to accommodate.
2. Gravies and Sauces
You can substitute coconut flour for cornstarch in gravies, though you’ll want to whisk carefully to avoid lumps.
3. Skip It for Clear Glazes
Cornstarch gives sauces a glossy, translucent look that coconut flour can’t match.
If you’re making a stir-fry sauce or fruit glaze, coconut flour will make it cloudy and slightly grainy.
So, Can You Substitute Coconut Flour for Cornstarch?
You can substitute coconut flour for cornstarch, but you’ll need to use less of it and add extra liquid to get the right texture.
It works well in soups, stews, and gravies, though it won’t give you the same glossy finish cornstarch does.
Use about half the amount, whisk it in gradually, and taste as you go.
With those adjustments, you can substitute coconut flour for cornstarch and still get a delicious result.
