What is the thickening agent for Whole30? A guide to compliant options

6 min read

Over 60% of people beginning a Whole30 program cite difficulty with meal preparation and finding compliant ingredient substitutions as a major challenge. A common stumbling block is figuring out what is the thickening agent for Whole30 recipes, as staple thickeners like cornstarch and flour are off-limits.

Quick Summary

Arrowroot powder and tapioca starch are popular Whole30 compliant thickening agents, often used as substitutes for cornstarch and flour. Other options include pureed vegetables, coconut flour, nut butters, and gelatin. Understanding the properties and best uses for each will help achieve the desired consistency in your recipes.

Key Points

  • Arrowroot and Tapioca Starch: These are the primary, compliant powdered starches for thickening sauces, gravies, and soups.

  • Cornstarch and Flour are Excluded: Common thickeners derived from grains like cornstarch and flour are not permitted on the Whole30 diet.

  • Vegetable Purees Work Naturally: Blending cooked starchy vegetables is an excellent whole-food method for thickening dishes.

  • Use a Slurry for Starches: Always mix arrowroot or tapioca with cold liquid before adding it to a hot pan to prevent clumping.

  • Compliance with Caution on Additives: Gums like xanthan gum are technically allowed, but they should be used sparingly to adhere to the program's whole-food focus.

Navigating Whole30 Compliant Thickeners

Following the Whole30 program means eliminating grains, legumes, sugar, and dairy for 30 days, which can make a lot of traditional cooking techniques obsolete. Thickening agents like all-purpose flour and cornstarch are derived from grains and are not allowed. Fortunately, several excellent alternatives can be used to create rich sauces, creamy soups, and perfectly bound meatballs without compromising your commitment to whole foods.

The All-Star: Arrowroot Powder

Arrowroot powder, also known as arrowroot flour or starch, is a superstar in the Whole30 kitchen and one of the most reliable options available. It comes from the root of a tropical plant and is a powerful thickener, requiring only small amounts to get the job done. Unlike cornstarch, which can become cloudy, arrowroot creates a clear, glossy finish, making it ideal for gravies and fruit fillings. To use arrowroot powder correctly, it is crucial to create a slurry by whisking it with a small amount of cold liquid before adding it to your hot dish. Adding it directly to a hot liquid will cause it to clump instantly. The best time to add it is at the end of the cooking process, as prolonged high heat can diminish its thickening power.

The Versatile Stand-In: Tapioca Starch

Tapioca starch, derived from the cassava root, is another widely used Whole30 thickening agent. It has a slightly different texture profile than arrowroot; tapioca tends to produce a more viscous, sometimes stringy, consistency, which can be fantastic for some applications but not all. Many home cooks prefer tapioca starch for baking or for giving a spongier texture to certain dishes. Like arrowroot, it must be added as a slurry to avoid lumps. However, be mindful when using it for dredging, as leaving it on meat for too long before frying can result in a gummy, tacky film. For best results, use it just before cooking.

Non-Starch Alternatives for Creaminess and Body

Not all thickening has to come from a powdered starch. Several whole-food options can add body and depth to your dishes without needing a slurry.

  • Pureed Vegetables: Blending cooked vegetables like sweet potatoes, cauliflower, or butternut squash into your soups and sauces is a naturally compliant way to add thickness and nutritional value. This is a popular technique for making creamy soups without dairy.
  • Coconut Flour: Because of its high absorbency, a little coconut flour can go a long way when used as a binder for meatballs or to thicken sauces. It does have a distinct flavor, so it's best in recipes where a subtle coconut taste is welcome.
  • Nut or Seed Butters: Almond butter or tahini can be used to thicken sauces, especially those with an Asian or Indian flavor profile. Ensure the ingredients list is compliant, with no added sugars or non-compliant oils.
  • Gelatin: While primarily known for desserts, gelatin powder can be used to thicken sauces and gravies. It's especially useful for dishes that will be served cold or at room temperature, as it creates a firm gel. For savory dishes, unflavored gelatin is best.
  • Reducing the Sauce: The simplest method requires no added ingredients. Simply simmer your sauce uncovered until the excess liquid evaporates and it reaches your desired thickness. This method also intensifies the flavor.

Whole30 Thickening Agents Comparison Table

Thickening Agent Best For Texture/Finish How to Use Best Practices
Arrowroot Powder Clear sauces, gravies, fruit glazes Clear and glossy finish Create a slurry with cold liquid, add at end of cooking Avoid prolonged high heat to prevent thickening loss
Tapioca Starch Baked goods, certain sauces, fruit pies Glossy, slightly stringy or chewy Create a slurry with cold liquid, whisk well Add near end of cooking; avoid over-mixing
Pureed Vegetables Soups, stews, creamy sauces Naturally creamy, opaque Blend a portion of cooked vegetables into the liquid Use starchy vegetables like sweet potato or cauliflower for best results
Coconut Flour Meatballs, pan-fried coatings, gravies Can be gritty, very absorbent Start with a small amount; adds distinct coconut flavor Use sparingly, as it absorbs a lot of liquid
Nut/Seed Butter Indian/Asian sauces, stews Creamy, opaque, adds nutty flavor Stir in small amounts until desired thickness is reached Ensure butter is Whole30 compliant (no sugar)
Gelatin Chilled sauces, gravies, desserts Firm, clear gel once cooled Sprinkle powder over cold liquid, let bloom, then heat gently Best for sauces that will be refrigerated

Using Additives and Recreating Experiences

While some additives are technically Whole30 compliant, it is important to remember the spirit of the program, which is centered on whole, unprocessed foods. Additives like xanthan and guar gum are technically allowed, but they are not whole foods. The official Whole30 program encourages minimal ingredient lists and prioritizing food with no label, like fresh produce. Furthermore, a compliant thickener should not be used to re-create a non-compliant experience, a concept known as "SWYPO" (Sex With Your Pants On). For example, creating a paleo-friendly, starch-thickened pancake is not allowed on Whole30, as it keeps you psychologically tied to old habits.

The Whole30 Philosophy on Thickening

The core of the Whole30 is about resetting your relationship with food. This means learning to appreciate the natural textures and flavors of whole foods rather than relying on processed ingredients to achieve a desired consistency. Embracing techniques like reduction, using vegetable purees, or creating a roux with compliant starches is a learning process that builds valuable culinary skills. It pushes you to experiment and find new, delicious ways to prepare meals without relying on old crutches like cornstarch and flour. The reward is not just a compliant meal but a deeper understanding of cooking from scratch.

Conclusion

For those on a Whole30 program, the quest for a compliant thickening agent leads to a variety of wholesome and effective alternatives. Arrowroot powder and tapioca starch are the go-to powdered thickeners, while pureed vegetables, nut butters, and gelatin provide additional avenues for adding body and creaminess. The simplest method, sauce reduction, requires no special ingredients at all. By embracing these natural thickeners and techniques, you can successfully navigate meal preparation on your Whole30 journey while staying true to the program's core principles of whole-food eating and culinary exploration.

Key Takeaways

  • Arrowroot is a go-to thickener: It's a reliable, Whole30 compliant replacement for cornstarch, creating clear, glossy sauces when used correctly.
  • Tapioca starch is another strong option: Derived from cassava, it provides a different texture and is also compliant, though it can become gummy if not used properly.
  • Pureed vegetables offer natural thickness: Blending cooked vegetables like sweet potato or cauliflower into your dishes is a whole-food way to add body and nutrients.
  • Reduction requires no added ingredients: Simmering a sauce to reduce its volume is a simple and effective method for thickening while intensifying flavor.
  • Remember the 'SWYPO' rule: Avoid using compliant thickeners to create foods that mimic non-compliant baked goods or treats, as this violates the program's spirit.
  • Some additives are okay, but use sparingly: While gums like xanthan and guar are technically compliant, the Whole30 promotes a whole-food approach, so minimal ingredients are best.
  • Proper technique is essential: Starchy thickeners like arrowroot and tapioca must be made into a cold liquid slurry before being added to hot dishes to prevent clumping.
