Ingredients & Variations

BUTTER: Real butter is best, feel free to add a splash of heavy cream to the mix at the end of cooking if you’d like.

MUSHROOMS: The best mushrooms to use for this recipe are the ones you like best! Try portabellas, mini Bellas, white mushrooms, or even wild mushrooms like oyster or morels!

WINE: White wine adds a great flavor to this recipe and it’s highly recommended. But if it must be left out, try a little bit of broth in place, this will change the flavor of the dish a little bit. Choose a dry white wine, something that you’d drink (more info on white wine for cooking here).

What to Serve with Mushrooms and Onions

The real question should be what not to serve because it’s hard to find things that don’t taste amazing with this recipe! Use them to dress up a delicious and economical dinner like Air Fryer Hamburgers or Perfect Pot Roast.

Make some crispy toast topped with buttery fried onions & mushrooms and serve with Avocado Toast and Zucchini Toast for an appetizer. Or mix it into Cauliflower Fried Rice for a brand new keto and low carb favorite. They also taste great next to an Omelette or alongside this Easy Quiche Recipe.

Favorite Recipe Tips

  • This combo also tastes great with cream mixed in, but if adding it, consider leaving out the soy sauce for a milder flavor profile.
  • Don’t let the onions burn, cook them slowly over medium heat.
  • I prefer softer onions so I start them first, the mushrooms need a bit less time.
  • Leftovers keep in the refrigerator up to 5 days.

  1. Thanks for your sautéed mushroom recipe; I’m anxious to try it. I’ve also used a robust red wine such as Burgundy to sauté mushrooms. Also very good.

    1. It is so delicious, Nancy! You can try it with red wine but we love this recipe with white wine too or you can omit it. Can’t wait for you to try it.

  2. Sauteed mushoom, onions– I’ve been making this for years. I add browned hamburger for a main dish. Add some noodles. Add noodles and hamburger. My kids loved it growing up.
