Umami Gravy

Step 1

Melt the butter in a large skillet over medium heat. Add the onion and sugar, and season with salt. Cook, stirring occasionally, until the onion is browned and caramelized but not burnt, 10 to 12 minutes.

Step 2

Add the oregano and flour and cook, stirring constantly, until the flour has been fully absorbed by the buttery onions, 30 seconds to 1 minute. Whisk in the vegetable stock and milk, raise the heat to high and, whisking occasionally, bring to a boil. Immediately reduce the heat to maintain a simmer and cook, still whisking occasionally, until the stock thickens into a loose gravy that thinly coats the back of a spoon, about 5 minutes.

Step 3

Whisk in the nutritional yeast, if using, and taste for seasoning, adding more salt and pepper as desired. Serve hot. (Alternatively, you can make this the night before Thanksgiving, cover and store it in the refrigerator, and reheat in the microwave or in a pot on the stove before serving.)
