Ah, mushrooms. They're one of those ingredients you either love or hate, and Ree Drummond doesn't just love them—she adores them! "I am hopelessly devoted to mushrooms," she says. They add a woodsy, umami flavor to many favorite mushroom recipes, from veggie burgers to pasta meals, and homemade pizzas too! If you're a fan of mushrooms and you've never tried mushroom gravy, you're been missing out. It's dreamy when ladled onto chicken fried steak, mashed potatoes or even slices of Thanksgiving turkey.

But the thing about mushrooms is that they can have a short shelf life. Before you know it, that carton of mushrooms has grown slimy, wrinkly and smelly, and there's nothing left to do but throw them out.

Like so many other foods, mushrooms can be frozen to keep them fresh and delicious for months... as long as you freeze them the right way! Keep reading for everything you need to know. Whether you grow your own mushrooms or are a fungi fanatic who keeps different types of mushrooms on hand at all times, let this be your guide to keeping them delicious for longer.

What is the best way to freeze mushrooms?

Start with mushrooms that are nice and fresh; it's best to avoid freezing any shriveled, slimy mushrooms. You'll need to clean them to remove any dirt—wipe them with a damp paper towel, brush them with a pastry brush, or give them a quick rinse with water, but be sure to dry them thoroughly. Mushrooms are like tiny sponges when it comes to absorbing moisture! Trim any woody parts from the stem and then cut larger mushrooms into uniform pieces; smaller mushrooms can be kept whole! The next step is to cook the mushrooms by sautéing them in a small amount of neutral oil or steaming them until they're fork-tender. Once the mushrooms have cooled completely, it's time to freeze them!
