This mushroom gravy is rich, creamy, and packed with flavor from oyster mushrooms, sherry, and fresh herbs. It's the perfect vegetarian gravy to serve over mashed potatoes or even hot biscuits!
Heat oil in skillet over medium-high heat. Add onion and saute 1 minute. Add thyme, salt, and mushrooms and saute about 8 minutes, or until mushrooms are browned. Add sherry and cook until liquid evaporates. Stir in broth.
Bring to a boil and cook until gravy is reduced to about 2 cups (about 14 minutes).
Whisk together flour and water in a small bowl. Add mixture to skillet; return to boil. Reduce heat to low and simmer until slightly thickened, about 2 minutes.
Remove from heat; stir in butter 1 tablespoon at a time and pepper.
Notes
This mushroom gravy is vegetarian, but can also be made vegan by simply substituting a vegan butter.
