Ingredients
onions (at least one)
garlic
2 or 3 boxes of mushrooms
about 4 Tbsp butter
1/4 cup flour
1/2 cup sherry
2 – 4 cups vegetable broth
thyme
You’ll need two pans. First you saute onions, garlic and mushrooms in one. Then make the roux in the second. Then add the first pan to the second pan, so second pan should be big!
Step 1 – Chopping
Since this is a gravy, I chop the ingredients finely. Minced onions, minced garlic, thinly sliced mushrooms. I almost never chop things finely, but it’s worth it. The liquids cook out faster and the gravy is smoother.
Step 2 – Sauteing
You can throw your ingredients in, fry ‘em up without thinking and have something that works, or you can pay attention, and have something great.
Fry the onions in a little butter or olive oil on high to medium high heat. We want really nice brown bits to give the gravy that great roasted taste. Obviously avoid burning them. Onions have quite a bit of liquid inside them, so they can take a pretty high heat, but once they start turning brown, pay more attention and stir more often to minimize the chance of burning.
Add the garlic when the onions are close to done. Garlic burns easily on high heat, so this is when you want to turn down the heat to medium or medium low.
Add the mushrooms. They’ll have a decent amount of liquid in them, so you want to cook them slowly to draw it out nicely for the sauce.
After the mushrooms have cooked down a little, add the thyme.
While the mushrooms are cooking, you can start the roux… (And if the mushrooms are done before the roux, you can take them off the heat until you’re ready for them, or vice versa.)
Step 3 – The Roux
The key to good gravy: mix the fat with the flour first. Then cook it. Then add the liquid.
So, equal parts fat and flour. For this recipe, about 4 tablespoons of butter and 1/4 cup flour. Melt the butter in a new pan (everything will end up in this pan at the end, so it should be reasonably big) over medium heat. Mix in the flour. It’ll bubble oddly. It looks and smells like Playdoh.
Keep stirring. You don’t want to burn it, but you do want to brown it. So medium heat is good. Lots of stirring. Thick bottomed pans are better here for an even heat.
I can usually tell that my roux is ready from the smell more than the color. It goes from smelling like Playdoh to smelling like baked pie crust.
Step 4 – Deglazing the Mushrooms
* I usually do this step at the same time as I’m making the roux to give the mushrooms more time to sit in the booze.
I just sprinkle as much sherry as I need, which is probably between 1/2. If you don’t have sherry on hand, you could use Marsala wine or vermouth, or red or white wine.
Once the fond is mixed into the liquid, you’re ready to add this to the roux.
Step 5 – Mixing it all together
Pour the mushroom bits into the roux. Stir a lot. It’ll foam up, but just keep stirring and pouring. The sauce should be thick and glossy. It’ll be too thick. This is when you add vegetable broth thin it out. Add a bit at a time until the consistency you want.
