Best gluten-free soy-free products for baking: 7 picks that cover both restrictions

Managing a gluten-free diet is hard enough. Throw a soy allergy or sensitivity on top of it, and suddenly most "safe" products on the shelf are off the table. This guide covers the best baking products that are both gluten-free and soy-free, so you can stop squinting at ingredient lists and start baking with confidence.

Key takeaways

• Many gluten-free baking mixes contain soy lecithin, soy flour, or soybean oil — always check the full ingredient list, not just the front label.
• Bob's Red Mill 1-to-1 Baking Flour, King Arthur Measure for Measure, and Namaste Foods Perfect Flour Blend are all gluten-free and soy-free all-purpose flour options.
• For fats, look for butter or coconut oil-based products instead of margarine or vegetable shortening, which frequently contain soy.
• Cassava flour and arrowroot powder are naturally both gluten-free and soy-free, making them reliable pantry staples.
• Hidden soy appears most often as soy lecithin in chocolate chips, vegetable oil blends, and nonstick cooking sprays.
• When in doubt, single-ingredient flours like almond flour, brown rice flour, and cassava flour are your safest bet.

Quick-reference table: gluten-free soy-free baking products at a glance

Why finding gluten-free soy-free baking products is so frustrating

Soy is everywhere in processed foods, and the gluten-free aisle is no exception. Manufacturers regularly use soy lecithin as an emulsifier, soybean oil as a cheap fat, and soy flour to improve texture in gluten-free blends. The result is that a product can proudly display a "gluten-free" label while still being completely off-limits for anyone avoiding soy.

We hear from readers all the time who feel like they're running out of options. The good news is that once you know which brands and products to trust, building a reliable soy-free, gluten-free pantry is absolutely doable. Let's walk through the best options category by category.

Best gluten-free soy-free all-purpose flour blends

The right flour blend is the foundation of everything you bake, and fortunately several excellent options are free of both gluten and soy.

Bob's Red Mill 1-to-1 Baking Flour

This is one of the most widely available gluten-free flour blends, and it's soy-free. It uses a combination of rice flour, tapioca starch, potato starch, and xanthan gum. We've used it in everything from cookies to quick breads with consistent results. You can read our full breakdown in our Bob's Red Mill gluten-free products guide to see how all their products stack up. The Bob's Red Mill 1-to-1 Baking Flour is available at most grocery stores and online.

King Arthur Measure for Measure Flour

King Arthur's blend is another excellent soy-free option that swaps directly for all-purpose flour. It contains rice flour, whole grain brown rice flour, tapioca starch, potato starch, and rice starch. We find it produces a slightly finer crumb than Bob's in cakes and muffins. If you're choosing between the two, our Bob's Red Mill vs King Arthur comparison breaks down the differences in detail. Grab the King Arthur Measure for Measure Flour if you want a refined texture in cakes and pastries.

Namaste Foods Perfect Flour Blend

Namaste is specifically formulated to be free of the top allergens, including soy, dairy, and nuts. It uses a blend of rice flour, tapioca starch, arrowroot powder, and potato starch. It's a great choice if you're managing more than two dietary restrictions at once. Check out our Namaste Foods product review for a full ranking of their lineup.

If you're juggling multiple dietary restrictions and want a structured approach to gluten-free baking, our Confident Gluten-Free Baker Toolkit walks you through flour blends, substitution ratios, and troubleshooting so you're not guessing every time you bake.

Best gluten-free soy-free baking mixes

Simple Mills Almond Flour Baking Mixes

Simple Mills makes some of the cleanest baking mixes on the market. Their ingredient lists are short — typically almond flour, arrowroot, and coconut sugar — and they're free of gluten, soy, dairy, and corn. They offer mixes for cookies, muffins, pancakes, cakes, and pizza dough. We go through their full product line in our Simple Mills product review. The Simple Mills variety packs are a great way to try several flavors without committing to a full box of each.

One thing to note: because these mixes are almond-based, they won't work for anyone with a tree nut allergy. If that's a concern, stick with the rice-flour-based blends above.

Best gluten-free soy-free baking chocolate

Enjoy Life Mega Chunks

Finding baking chocolate that's both gluten-free and soy-free is one of the biggest pain points we hear about. Most chocolate chips — even premium brands — contain soy lecithin as an emulsifier. Enjoy Life is the gold standard for allergen-free baking chocolate. Their Mega Chunks are free of the top 14 allergens, including gluten, soy, dairy, and nuts. They melt well, taste great, and hold their shape in cookies. The Enjoy Life Mega Chunks are a pantry essential if you're managing both restrictions.

Best gluten-free soy-free baking fats

Spectrum Organic Shortening

Most vegetable shortenings are made from partially or fully hydrogenated soybean oil. Spectrum Organic Shortening is made from palm oil instead, making it both gluten-free and soy-free. It performs well in pie crusts, biscuits, and any recipe where you need a solid fat. For pie crust tips, check out our guide to gluten-free pie crust recipes from scratch.

Butter is also naturally soy-free and gluten-free, so if dairy isn't a concern, regular unsalted butter is always a safe choice. Coconut oil is another reliable option — just keep in mind it adds a slight coconut flavor to some recipes.

Otto's Cassava Flour

While not a fat, Otto's deserves a mention as a single-ingredient flour that's a powerhouse for soy-free and gluten-free baking. It behaves more like wheat flour than most alternatives, making it ideal for tortillas, flatbreads, and recipes where you want a stretchy, pliable dough. Our cassava flour vs gluten-free flour blend comparison explains when to reach for cassava versus a pre-made blend.

Watch out for: hidden soy in gluten-free products

This is the section that could save you a lot of frustration. Soy hides in gluten-free products more often than you'd expect, and it doesn't always show up where you think it will.

Soy lecithin in chocolate and candy

This is the most common culprit. Soy lecithin is used as an emulsifier in nearly all conventional chocolate chips, baking bars, and candy melts. Even brands that are certified gluten-free almost always contain soy lecithin. Always check the ingredient list, even on dark chocolate.

Soybean oil in "vegetable oil"

When a product lists "vegetable oil" as an ingredient, it's frequently soybean oil. This shows up in baking mixes, nonstick sprays, and pre-made frostings. Look for products that specify the oil type — coconut oil, sunflower oil, or avocado oil are all soy-free alternatives.

Soy flour in gluten-free bread products

Some gluten-free bread and bread mixes use soy flour to boost protein content and improve texture. This is less common in flour blends but does appear in ready-to-eat gluten-free breads and some pancake mixes.

Natural flavors and additives

"Natural flavors" can occasionally be derived from soy. If you have a severe soy allergy, contact the manufacturer directly when you see this on a label. For a baking sensitivity (rather than a true allergy), this trace amount is usually not an issue, but it's worth knowing about.

Tips for building a gluten-free soy-free baking pantry

Once you have your core products sorted, stocking a reliable pantry gets much easier. Here's what we recommend keeping on hand:

• Flour blend: Bob's Red Mill 1-to-1, King Arthur Measure for Measure, or Namaste Perfect Blend
• Single-ingredient flours: Almond flour, brown rice flour, and cassava flour for specialty recipes
• Starches: Arrowroot powder and tapioca starch for binding and lightening
• Chocolate: Enjoy Life Mega Chunks or mini chips
• Fats: Unsalted butter (if dairy is fine), coconut oil, or Spectrum Organic Shortening
• Leaveners: Baking powder (most major brands are soy-free, but double-check) and baking soda
• Binders: Xanthan gum or psyllium husk powder — both naturally soy-free

Frequently asked questions

Is Bob's Red Mill gluten-free flour soy-free?

Yes, Bob's Red Mill 1-to-1 Baking Flour is both certified gluten-free and soy-free. Their ingredient list includes rice flour, tapioca starch, potato starch, and xanthan gum — no soy-derived ingredients. However, always check the label on other Bob's Red Mill products, as their full lineup varies. Our complete Bob's Red Mill guide covers every product in detail.

Do gluten-free chocolate chips contain soy?

Most conventional chocolate chips contain soy lecithin as an emulsifier, even if they're gluten-free. Enjoy Life is the most widely available brand that makes chocolate chips free of both soy and gluten. Some specialty brands also offer soy-free options, but Enjoy Life is the easiest to find in stores and online.

What gluten-free baking mixes are also soy-free?

Simple Mills, Namaste Foods, and select Bob's Red Mill mixes are both gluten-free and soy-free. Always verify by reading the full ingredient list, as formulations can change. Avoid mixes that list "vegetable oil" without specifying the source, as this is often soybean oil.

Can I use cassava flour for gluten-free soy-free baking?

Absolutely. Cassava flour is a single-ingredient flour that's naturally free of gluten, soy, nuts, and dairy. It works well as a 1-to-1 substitute for wheat flour in some recipes, particularly flatbreads and tortillas. For cakes and cookies, you may get better results blending it with a starch like arrowroot or tapioca. Our cassava flour vs gluten-free flour blend guide explains when each option works best.

Is xanthan gum soy-free?

Yes, xanthan gum is naturally soy-free. It's produced by fermenting sugars (usually from corn or wheat, though the final product is gluten-free). It's one of the most important binders in gluten-free baking, and you don't need to worry about soy contamination. Learn more about how it compares to other binders in our xanthan gum vs guar gum comparison.
