There’s something wonderfully comforting about a rich, homemade mushroom gravy. Deeply browned mushrooms, sweet shallots, fresh thyme, and a splash of dry sherry create layers of savory flavor, while vegetable stock brings everything together in a smooth, velvety sauce. It’s the perfect accompaniment to our Wild Mushroom and Leek Wellington, but equally delicious spooned over mashed potatoes, roasted vegetables, stuffing, or savory bread pudding.
Unlike traditional turkey gravy, this vegetarian version gets its flavor from caramelized mushrooms and aromatic vegetables rather than pan drippings. The result is every bit as satisfying—and a lovely addition to any Thanksgiving table.
INGREDIENTS:
3 tablespoons extra-virgin olive oil
12 ounces cremini mushrooms, finely chopped
2 medium shallots, finely minced
2 garlic cloves, minced
3 tablespoons all-purpose flour
¼ cup dry sherry (optional)
3 cups low-sodium vegetable stock, preferably mushroom or vegetable stock with a rich flavor
1 tablespoon soy sauce or tamari
1 teaspoon fresh thyme leaves, chopped
½ teaspoon finely chopped fresh rosemary
1 teaspoon Dijon mustard
1 teaspoon balsamic vinegar
Freshly ground black pepper, to taste
Kosher salt, as needed
1 tablespoon cold unsalted butter or extra-virgin olive oil, optional, for finishing
METHOD:
Heat the olive oil in a large, heavy-bottomed skillet or saucepan over medium-high heat. Add the mushrooms and cook, stirring occasionally, until they release their moisture and begin to brown, about 10–12 minutes. Allow them to develop some deep golden color; this is where much of the gravy’s flavor comes from.
Reduce the heat to medium. Add the shallots and cook for 3–4 minutes, stirring frequently, until softened. Add the garlic and cook for another 30 seconds, just until fragrant.
Sprinkle the flour over the mushroom mixture and stir thoroughly to coat. Cook for 2 minutes, stirring constantly, to eliminate the raw flour taste.
If using sherry, pour it into the skillet and stir, scraping up any flavorful browned bits from the bottom of the pan. Cook for about 1 minute.
Gradually whisk in the vegetable stock, a little at a time, stirring until smooth. Add the soy sauce, thyme, rosemary, and Dijon mustard.
Bring to a gentle simmer, then reduce the heat to medium-low. Cook uncovered for 10–15 minutes, stirring occasionally, until the gravy thickens enough to lightly coat the back of a spoon. If it becomes too thick, add a little additional stock.
Stir in the balsamic vinegar and season with freshly ground black pepper. Taste before adding salt, as the stock and soy sauce may already provide enough seasoning.
For a completely smooth gravy, carefully purée with an immersion blender, or transfer to a blender in batches, allowing steam to escape according to the manufacturer’s instructions. For a more rustic gravy, leave the mushroom pieces intact. Just before serving, stir in the cold butter or a drizzle of olive oil for added richness and sheen.
Transfer to a warmed gravy boat and serve alongside the Wild Mushroom and Leek Wellington.
YIELD: Makes about 3 cups or 8–10 servings
COOK’S NOTES
Choosing Mushrooms: Cremini mushrooms are economical and have excellent flavor, but a mixture of cremini and shiitake is especially delicious. For even greater depth, add a small handful of rehydrated dried porcini mushrooms, finely chopped, and replace some of the stock with their strained soaking liquid.
For a Smooth, Restaurant-Style Gravy: I particularly like blending approximately half the finished gravy and stirring it back into the pan. This creates a luxurious texture while retaining a few small pieces of mushroom.
Make Ahead: Prepare the gravy up to three days in advance. Cool promptly and refrigerate in an airtight container. Reheat gently in a saucepan, stirring occasionally and adding a splash of vegetable stock to restore the desired consistency.
Freezing: Freeze in airtight containers for up to three months. Thaw overnight in the refrigerator and reheat thoroughly.
For a Vegan Gravy: Use olive oil instead of butter for the finishing step.
For a Gluten-Free Gravy: Substitute a gluten-free all-purpose flour blend suitable for thickening sauces, or use a cornstarch slurry toward the end of cooking instead of making a flour-based roux.
A Note About Sherry: Dry sherry adds lovely complexity, but it’s optional. For an alcohol-free variation, substitute additional vegetable stock with a small splash of apple cider vinegar to provide brightness.
What Makes This Gravy Special?
One technique I’d emphasize is allowing the mushrooms to brown properly before adding the shallots. When mushrooms are crowded into a pan, they initially release moisture and steam. Once that liquid evaporates, their flavor becomes concentrated and they begin to caramelize. It’s worth spending those extra few minutes.
And here’s another little trick: don’t use too much rosemary. It’s delicious with mushrooms but can easily overpower the more delicate thyme and sherry. We want the mushrooms to remain the star.
For Thanksgiving, I’d prepare this gravy the day before. Then, while the Wellington is resting after baking, the gravy can be warming gently on the stove.
