How to Clean Mushrooms
When cleaning mushrooms, you want to wipe them down or very gently rinse them instead of soaking them in water.
Mushrooms absorb water and can become mushy, so it is not a good idea to let them take on too much water.
- If using whole mushrooms, before slicing, wipe each mushroom down with a damp paper towel. You can gently rinse the mushrooms under cool water, but you must dry them with paper towels completely after rinsing. Don’t let them soak!
- If using sliced mushrooms, and you want to give them an extra clean, place them in a colander and rinse under cool water. Once again, make sure to dry them with a paper towel and do not let them soak.
Mushrooms and Onions for Steak
My favorite way to serve these savory mushrooms is over steak recipes! You can take a grilled chuck steak and create an amazing steakhouse experience by topping it with these mushrooms. At our house, ribeye steaks are always a favorite and nothing elevates them more than this recipe.

Onions and Mushrooms Recipe Tips
- Don’t burn the butter. Please be careful not to burn the melting butter. If you do, you will have to start all over!
- Cook the mushrooms over medium-high heat. Since they release a lot of moisture, they must be cooked over high heat and stirred constantly so they do not burn.
- Try another type of mushroom! We used white mushrooms in this sautéed onions and mushrooms recipe, but we also love shiitake mushrooms or baby portobello mushrooms if you prefer.
Mushrooms and Onions FAQs
Interestingly, in scientific terms, mushrooms are not a vegetable, they are edible fungi. In culinary terms, mushrooms are basically a vegetable. They are used as a savory ingredient in recipes, usually to complement meats or other vegetables.
I love the fact that mushrooms are very healthy for you! According to an article from Medical News Today, mushrooms are packed with nutritional value, from fiber and protein to important nutrients like Vitamin B and D. They’re also a great source of protein for those on a plant-based meal plan. Plus, we pair them with onions, which are low in calories and also contain fiber and important nutrients.
You can freeze sautéed mushrooms and onions. After sautéing the dish, let it cool, then transfer to an air-tight container and freeze for up to three months. Make sure to label the container.
How to Reheat Frozen Mushrooms
To reheat, first, let them thaw in the refrigerator. Then, reheat in a skillet with a few tablespoons of butter over medium heat, until the dish warms through. Serve, and enjoy!
