Heat the olive oil in a sauce pan over medium-high heat.
3 Tablespoon extra virgin olive oil
When the oil begins to shimmer, whisk in the flour. Whisk constantly for about 1-2 minutes until the flour begins to smell a bit nutty.
¼ cup flour
Add the nutritional yeast and continue to whisk for one more minute.
3 Tablespoon nutritional yeast
Add ½ cup of the broth and whisk into the flour mixture so that it is smooth and there are no lumps.
2 cups good quality vegetable broth
Add the remaining broth.
Simmer the gravy, whisking constantly, until it begins to thicken and is bubbling. This could take about 5 minutes.
Reduce the heat to low, and whisk in the dried thyme, some freshly cracked black pepper, and 1 teaspoon of Marmite.
½ teaspoon dried thyme, freshly cracked black pepper, 1-2 teaspoons Marmite
Taste your gravy and decide whether you want to add a bit more Marmite, and adjust the seasonings as necessary.
Transfer to a gravy boat, and serve hot!
