Vegan Onion Gravy is easy to make from scratch with only 6 ingredients in 30 minutes. Try it on mashed potatoes, roasted vegetables, and your favorite comfort foods. It's perfect for Thanksgiving, holiday dinners, and any night of the week!
For my family, it simply isn't Thanksgiving without dairy-free olive oil mashed potatoes and gravy. And if you're preparing a meatless holiday meal for the first time, great news! It doesn't get much easier than making Vegan Onion Gravy.
Inspired by my recipe for vegan mushroom gravy, this version is also loaded with savory flavor while requiring minimal time and ingredients. Plus you can make it in advance and reheat it so your holiday dinner preparation is less stressful.

Vegan onion gravy is easy to customize to suit your taste. Start with the basic recipe and go from there.
- Combine the onions with garlic and shallots.
- Add nutritional yeast or miso for additional umami flavor.
- Include other herbs with the thyme like sage and rosemary.
- Use fresh herbs in place of dried.
- Stir in a splash of balsamic vinegar.
- Prefer a smooth gravy? Use an immersion blender or carefully transfer it to a regular blender and blend it before serving.
Storing and freezing
Store leftover gravy in an airtight container in the refrigerator for 3 to 4 days, or freeze it for up to 3 months.
Refer to the FDA Food Storage Guidelines for more information.
An equal amount of potato starch or arrowroot powder can be used in place of cornstarch. You can also use tapioca flour, but you will need to double the amount.
Tamari is similar to soy sauce but is made with only soybeans and no wheat, making it gluten-free.
If you prefer a smoother gravy without chunks of onions, you can blend part or all of the gravy using an immersion blender. Or carefully transfer it to a regular blender and blend until smooth.
