Plus, I have finally learned the secret to avoiding lumpy gravy, and lumpy sauces in general. Fat first!
I first started making mushroom gravy with canida, but she's less vegetarian now, so she's only documented meaty gravy. I decided to fix the lack of vegetarian instructable when my sister called me for tips last weekend.
Step 1: Ingredients
- onions (at least one)
- mushrooms (portabella or baby bella are best)
- about 4 Tbsp butter (olive oil would probably work, but I've never tried)
- 1/4 cup flour
- 1/2 cup sherry or marsala (other flavored liquids would work, but these have the best flavor here)
- 2 - 4 cups liquid (ideally vegetable broth)
- garlic (as much as you like)
- thyme, dried or fresh
- fresh parsley
Step 2: Chopping
Step 3: Sauteing
1. 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.
2. 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.
3. Add the mushrooms. They'll have a decent amount of liquid in them from the washing, so we want to cook them slowly to draw it out nicely for the sauce. This time I ended up adding one box of mushrooms first, then chopping and adding the second. This led to a nice gradation from totally cooked mushroom bits to fairly solid mushroom slices. If I weren't so lazy I might have cooked them longer, for a smoother gravy, but a few slices are nice too.
4. After the mushrooms have cooked down a little, add the thyme and paprika. I tend to sprinkle, mix, smell or taste, and repeat the process until I'm happy.
I'm horrible at estimating times for these steps, and it's more important to get it to the right doneness than check the time. But the onions might take 10 minutes, the garlic may take 1 minute, and the mushrooms another 10 minutes. But 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 4: Roux -- The basis of European sauciness
So, equal parts fat and flour. For this recipe, about 4 tablespoons of butter and 1/4 cup flour. (Yes, those are equivalent amounts. Silly Imperial system.) 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. Kind of gross, right?
Keep stirring. And stirring. And 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. And basically, that's what it is, cooked butter and flour. It just happens to be liquid instead of solid.
Step 5: Deglazing the mushrooms
I just sprinkle as much sherry as I need, which is probably between 1/2 and 1/4 of a cup. All of the alcohol cooks off, so we're just doing it for the rich flavors. If you don't have sherry on hand, you could use Marsala wine or vermouth, or red or white wine. I think at one point I used a mix of apple cider vinegar and water, but that was a long time ago.
Once the fond is mixed into the liquid, you're ready to add this to the roux.
Step 6: Mixing it all together
See how the sides of the pan are nicely coated with thick gravy? Yum.
This is where you could mix in some minced fresh parsley.
