    How to Make Gluten-Free Roux: it's one of the basics you need to know! This recipe for gluten-free roux also offers a dairy-free version, plus tips & tricks for getting gluten-free roux just right.

    We've also included options for gluten-free brick roux and a grain-free roux.

    White Lasagna with Mushrooms, Spinach and Artichokes recipe

    Can you make thick, rich gluten-free sauces & gravies? Yes, you can.

    This White Lasagna starts with a roux that becomes a creamy mushroom sauce. Who wouldn't want that? Nobody, that's who.

    You can use this roux to make your own gluten-free sauces and recipes, or convert conventional favorites, like sausage gravy.

    What to use the roux for, and roux colors or "stages"

    Roux is used for thickening gravies, soups, sauces - all kinds of delicious things. Many recipes call for a white or blond roux, which simply refers to the color of the mixture as it cooks. Gumbo and a few other dishes call for a "brick" roux (or a dark roux). This just means that the mixture is cooked until it gets brick red- just before it burns! 

    Pro Tip: don't take gluten-free roux much past the "peanut butter" stage

    Because gluten-free flour acts a little differently than wheat flour, I don't recommend making gluten-free roux much darker than peanut butter colored. Going darker than that can result in a burnt or scorched taste, even if the gluten-free roux doesn't look burned. I also don't make the roux in the oven, because I think you really need to keep an eye on it.

    Choosing gluten-free flour for roux:

    I usually use one of my favorite gluten-free flour blends to make roux, along with butter or olive oil. My favorites are Pamela’s Gluten-Free Artisan Blend or King Arthur Gluten-Free All-Purpose blend (not the King Arthur Measure for Measure blend). Neither of these blends contains dairy- some GF blends do. Also, the Pamela's has limited gum binder, and the recommended King Arthur blend had no gum binder. You can also use a mixture of rice flour and tapioca flour/starch. Our favorite rice four is Mochiko Sweet Rice Flour from Koda Farms.

    You want a blend with starches like tapioca, potato or corn, but no or limited gum-binders.

    Can you make grain-free roux? Yes.

    If you'd like to make your roux grain-free, the best option I've found is using a mixture of cassava flour and tapioca starch.

    What do you need to make this roux recipe gluten-free?

    Making gluten-free or gluten-free dairy-free roux doesn't take much. Here's what you need:

    Supplies:

    • heavy duty saucepan or skillet
    • whisk

    Ingredients:

    • butter or olive oil
    • gluten-free flour blend -OR- sweet rice flour + tapioca starch

    Making red roux gluten-free:

    Since gluten-free roux shouldn't go beyond the peanut butter stage, we use the same method for brick roux as Cajun-cooking expert and Louisiana chef Isaac Toups - adding tomato paste. To make a gluten-free brick roux, first make a GF blond roux. Once the blond roux is ready, add ½ cup (120 ml) tomato paste. Stir the paste in and let it caramelize until it starts sticking to the bottom - about 5 minutes. The result is a thick brick red roux with a charred tomato flavor. Get more Cajun recipes in Issac's cookbook Chasing the Gator.

    Making dairy-free roux:

    You’ll notice I use a little less olive oil than butter when I make dairy-free roux. That’s because the consistency of the oil is different than butter. Roux is usually half butter-half flour, and I've tried all kinds of dairy-free fats and oils. I'm convinced if you need GFDF roux, the scant-olive-oil-way is the best way.

    Now you're ready to make gluten-free Bechamel Sauce or one of your other favorites.

    Gluten-Free Bechamel Sauce

    Use your roux to make Gluten-Free Bechamel Sauce/White Sauce:

    This Gluten-Free Béchamel Sauce recipe can be made with or without dairy, and it always comes out beautifully.

    Frequently asked questions about gluten-free roux:

    Can you use gluten-free flour for a Roux?

    Yes, but the blend matters. Don't use an all-nut blend or a blend with tons of binders. Our favorites are Pamela’s Gluten-Free Artisan Blend or King Arthur Gluten-Free All-Purpose blend, which has less binders then their Measure for Measure blend. You can also use finely ground sweet rice flour, our favorite is from Koda Farms, with a bit of tapioca starch.

    Can almond flour be used to make a roux?

    All-nut flours won't thicken the same way as conventional flour or a GF blend. If you want to make a grain free roux, the best bet is to use a blend of arrowroot or tapioca starch and cassava.

    What is the best gluten free flour to use for thickening sauces or gravy?

    The best options to use as a universal cooked thickener like roux are rice flour + tapioca flour or a gluten-free all purpose blend. Arrowroot, cornstarch or tapioca slurries will work if you're trying to thicken a sauce without starting from a roux.

    Will gluten free flour thicken a sauce?

    Yes, absolutely. Be sure to use a blend that has some starch and/or binders, Pamela’s Gluten-Free Artisan Blend or King Arthur Measure for Measure blend.

    Can you make gluten-free and dairy-free roux?

    Yes. Use olive in a slightly reduced measurement for the fat, along with a gluten-free flour blend, and an unsweetened plant-based milk if you're making a white sauce or gravy.

    Are tapioca starch and tapioca flour the same?

    Yes. Tapioca flour and tapioca starch are the same product. That is not the case with potato flour/potato starch or corn flour/corn starch/corn meal, so it can be confusing.

      Thank you for the information. You have a typo and a word omission in the first sentence under the heading "Choosing gluten-free flour for roux + making it dairy-free too".
      You sound like you really know your stuff but it is a bit hard to take you completely seriously when one has to guess what is trying to be communicated.

          Thank you so much for this recipe! I've had to be gluten-free and corn-free for years, but never thickened a sauce because I couldn't find a flour blend without gums, which I can't have.After all this time, I finally found a no-gums flour blend. I'm so anxious to try out the roux with a variety of sauces. This will expand my choices! Again, thank you!
