Sautéed Mushroom and Onions 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 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.

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.

How to Store Saute Mushroom and Onions

1. Cool Down: Let the sautéed mushrooms and onions cool to room temperature.
2. Container: Put them in a clean, airtight container.
3. Refrigerate: Store them in the fridge for 3-5 days.
4. Freezing: If you want to store them for a longer period, you can freeze sautéed mushrooms and onions. Place them in a freezer-safe container or heavy-duty freezer bag, removing as much air as possible. Properly sealed, they can last for up to 3 months in the freezer. However, note that freezing can change their texture slightly upon thawing.
