Servings: 6
- 1 small yellow onion
- 12 oz. mushrooms (I use cremini)
- 1 Tbsp. red wine vinegar
- 1 Tbsp. tamari
- 1-2 tsp. fresh thyme (or 1/2 tsp. dried thyme)
- 1 tsp. garlic powder
- 1/2 tsp. Italian seasoning
- 2 1/2 cups vegetable broth
- 1/4 cup all-purpose flour (GF if desired*)
Finely dice the onion. Slice the mushrooms and set aside.
In a skillet over medium-high heat, sauté onion for 4-5 minutes. (I use 3 Tbsp. water/broth for no-oil sauté method, adding more as needed.)
Then add mushrooms. Sauté for 7-8 minutes or until softened.
Meanwhile, finely chop the fresh thyme leaves (stems removed) and set aside.
When the onions are translucent, add the red wine vinegar, tamari, fresh thyme, garlic powder and Italian seasonings. Stir and cook for 1 minute.
In a medium bowl, whisk together the broth and flour. (This helps prevent the flour from clumping and congealing.)
Then slowly pour the broth & flour mixture into the pan.
Bring to a very light boil, stirring often with a spatula to prevent sticking. Then reduce heat and lightly simmer for 8-10 minutes until thickened. Adjust the flavors if desired (more herbs, tamari, salt & pepper, or even vegan butter for added richness).
*For gluten-free: Use tamari and GF flour. (I use Bob's Red Mill GF all-purpose flour.)
Herbs: Change up the herbs as you see fit. I've used combinations of rosemary, thyme, oregano, and sage.
Yield: Recipe makes about 3 heaping cups gravy. (For us, this is enough for about 3-4 lbs. potatoes.)
