This vegan mustard sauce is creamy and simple to put together. It’s sweet, salty, tangy, and oil-free. The dressing uses tamari which gives the sauce a salty umami flavor, maple syrup for a little sweetness, and of course, the main flavor driver is spicy brown mustard for a tangy flavor.

The mustard dressing was made for a mustard tempeh bowl with sweet potatoes, kale, avocado, apple, and baked tempeh. The dressing has a strong assertive flavor to coat those bitter greens like kale but would go great on any grain bowl or Buddha bowl.
For another mustard sauce, try vegan honey mustard that uses dijon mustard and maple syrup. It works great as a dip or thin it out with water to make a dressing.

Substitutions
- Dijon mustard can be substituted if you prefer a tangier kick.
- Whole-grain mustard can also be substituted for a dressing with a coarser texture and no kick.
- Agave can be used instead of maple syrup.
Tips
- Stir the tahini before measuring.
- If you prefer a thinner consistency, add a splash of water to thin the dressing out.
- Use 2 tablespoons of tamari for a sweeter sauce, and use 3 tablespoons of tamari for a more savory sauce.
Instructions
Measure out all of the ingredients, add them together, and whisk until smooth. Yep, that’s it!

Storage
The mustard sauce is great for meal prep! Store a batch in an air-tight container for about a week in the refrigerator.
Serving suggestions
With just a few simple ingredients this vegan mustard sauce can be whipped in about 5 minutes. It's very versatile and can be used as a dressing or dip.
- Try it on a mustard tempeh Buddha bowl, with sweet potatoes, apples, avocado, and tempeh.
- Use it for any Buddha or grain bowl.
- Add it to a salad with hearty greens.
