If you love sustainable recipes, you’re going to enjoy this! Let’s dive into the step-by-step process of making homemade soybean mayo.


Why Soybean Mayo Is Unique
The key ingredient that makes this mayo truly special is fresh soybeans. Unlike traditional mayo, which typically relies on processed oils and eggs, using soybeans as a base provides a plant-based protein boost, making it plant-based and more nutritious. Soybeans are rich in fiber, vitamins, and healthy fats, giving this mayo a nutritional edge over conventional versions.
By swapping out eggs for soybeans, you’re opting for a more eco-friendly option, as soybean cultivation generally has a smaller carbon footprint than animal-based products. This recipe not only enhances your diet but also aligns with sustainable living!
Health Benefits of Homemade Soybean Mayo
- Plant-Based Protein: Fresh soybeans provide a great source of plant-based protein, making this mayo a nutritious option.
- Heart-Healthy Fats: Olive oil, a key ingredient, is rich in healthy monounsaturated fats that support heart health and reduce inflammation.
- Rich in Antioxidants: Olive oil is packed with antioxidants, which help protect the body from oxidative stress and reduce the risk of chronic diseases.
- No Artificial Additives: By making your own mayo, you avoid preservatives and artificial ingredients found in many store-bought versions.
- Customizable for Diets: You control the salt, flavor, and other ingredients, allowing you to adjust it for low-sodium or other dietary preferences.
- Lower in Saturated Fats: Without the use of eggs or heavy oils, this version has less saturated fat compared to traditional mayo, making it a lighter alternative.
How to Make Homemade Soybean Mayo
Making this homemade mayo is simple and rewarding. Here’s a step-by-step guide based on the recipe Albert and I put together.
Ingredients:
- 1 cup soymilk (made from fresh soybeans)
- 1 cup olive oil
- 1 tbsp mustard
- 1 tbsp maple syrup
- Vinegar and lemon juice (to taste)
- Salt and garlic (to taste)
Instructions:
- To start, add water to your fresh soybeans and mix them thoroughly to loosen the shells. Once separated, compost the shells to keep things zero-waste!
- After that, blend the de-shelled soybeans with a little water until smooth. Strain the mixture to produce fresh, silky soymilk. Next, cook the strained soymilk to remove any bitterness, ensuring your mayo has a smooth and pleasant flavor.
- In a blender, mix 1 cup of your homemade soymilk with 1 cup of olive oil, 1 tablespoon each of mustard and maple syrup, along with vinegar, lemon juice, salt, and garlic. Blend until the mixture becomes smooth and creamy.
- Transfer your soybean mayo to a jar and refrigerate it for a few hours, allowing the flavors to meld and the texture to thicken perfectly.
Making your own mayo allows you to use fresh, plant-based ingredients that are not only better for you but also more environmentally friendly. It’s a win-win for those who prioritize sustainability and healthy eating.
Give this recipe a try, and you’ll discover that homemade mayo elevates the flavor of your dishes to a whole new level. It’s a treat you can feel great about sharing with friends and family!
