How To Clean Mushrooms

There is such a wide array of mushrooms in this world but all must be cleaned. I know the most sought after way to clean them off is to run them under water. Yes, the dirt and moss and other stuff is not appealing. But! You don’t want the mushroom to soak up all that water. The best way to clean a mushroom is with a damp cloth or paper towel. Just rub them from the top downward. This will stop the top layer of skin from pealing off. Trim the stub off and clean the underneath gently trying not to destroy the gills under the mushroom.

How To Make Roasted Butter Garlic Mushrooms

This is not your average mushroom side dish because mushroom recipes are mainly sautéd in a pan on the stove. This recipe is different because they are roasted in the oven and then the butter garlic sauce is added after.

I like this dish because it is so easy, quick and tasty. Just spray the mushrooms with an olive oil spray and then add the onion salt, sea salt, chives and black pepper. Put them in the pre-heated 400 degree oven and bake them for 20 minutes. At 10 minutes take them out and tern them over.

While the mushrooms are roasting make the butter garlic sauce. Mince up all of the garlic into small bits and pull off about a heaping tablespoon of fresh thyme. Wait to start heating the butter until the mushrooms are half way done in their roasting time. If the mushrooms are shrinking fast because they maybe small then only cook them for 5 more minutes. Then start heating the butter. Heat the butter first until it completely melts and gets a little darker. Then after the mushrooms come out of the oven add the minced garlic and fresh thyme to the butter. Pour over the mushrooms and toss around with all the oil and spices in the baking dish. Serve immediately!
