Also gluten-free, this vegan gravy is the perfect accompaniment to my seitan wellington, a hearty main dish that is perfect for the holidays.

Learn how to make this simple caramelized onion gravy step by step on YouTube, in this vegan 5-course Thanksgiving dinner tutorial video. In addition to serving it over a vegan roast, this caramelized onion gravy would also be perfect served over fluffy mashed potatoes or alongside other vegan Thanksgiving recipes.

In this recipe, I included a way to speed up the process of caramelizing the onions! We will quickly steam the onions so they release their liquids and can begin to caramelize much quicker.

The caramelized onions, along with aromatic garlic, sage, and thyme, will form the base for this vegan gravy. It's blended until smooth and reheated when ready to serve.

Equipment

• 1 High-Speed Blender

Ingredients

  

• 1 ½ sweet or yellow onion
• ½ teaspoon salt
• ⅓ cup water
• 1 tablespoon oil
• 3 cloves garlic minced
• 1 tablespoon fresh sage chopped
• 2 tablespoon fresh thyme chopped
• 2 tablespoon cornstarch
• 2 ½ cups vegetable broth
• 2 tablespoon tamari or soy sauce
• 1 teaspoon mushroom umami seasoning or mushroom powder optional

Instructions

 

• Thinly slice onion. Add to a pan over medium-high heat with salt, water, and oil. Stir and cover with a lid to steam for about 15 mins, until the water has evaporated.
  1 ½ sweet or yellow onion, ½ teaspoon salt, ⅓ cup water, 1 tablespoon oil
• Add garlic, sage, and thyme, and sauté until the onions are caramelized and brown. This is easiest done if you leave the onions in a single layer without stirring, and flip them over when they start to brown. This will take at least 10 more mins.
  3 cloves garlic, 1 tablespoon fresh sage, 2 tablespoon fresh thyme
• Once your onions are caramelized, add the mixture to a blender, along with, cornstarch, vegetable broth, tamari, and umami seasoning. Blend until it is extremely smooth and no lumps remain.
  2 tablespoon cornstarch, 2 ½ cups vegetable broth, 2 tablespoon tamari or soy sauce, 1 teaspoon mushroom umami seasoning or mushroom powder
• Return the blended mixture to a saucepan and bring to a soft simmer, to heat and thicken, before serving. If you want, you can thin it out by adding water 1 tablespoon at a time until you reach your desired consistency. Remove from heat and serve!
