How Do You Make Sauteed Mushrooms And Onions?

Start by melting some butter in a large skillet, then add sliced onions. Cook the onions until they are soft and starting to caramelize. Add the mushrooms to the pan, then continue to cook until everything is tender and browned. This may take some time, as the mushrooms will need to release all of their liquid before they start to brown. Stir in garlic, Italian seasoning and a dash of Worcestershire sauce for extra flavor. Finally, top the vegetables with a sprinkle of fresh parsley, then serve and enjoy.

Tips For The Perfect Sauteed Mushrooms And Onions

  • You can use any variety of mushroom that you like in this dish, or even a blend of different types of mushrooms. I typically use cremini or white button mushrooms, but other great options include chanterelle, oyster, portobello, baby bellas or shiitake mushrooms.
  • This recipe pairs well with a variety of main course options including turkey meatloaf, crack chicken, Yankee pot roast, cheeseburger meatloaf and bacon ranch chicken.
  • Sauteed mushrooms and onions will stay fresh in the refrigerator for up to 3 days. Reheat them over low heat in a skillet until everything is warmed through.
  • For a richer sauce, stir in 1/4 cup heavy cream and 2 tablespoons of grated parmesan cheese.
  • You can make this recipe vegan by using olive oil instead of butter.
  • This recipe can easily be doubled or tripled to serve a crowd.
  • No parsley on hand? Try using fresh thyme, basil or chives instead. You can also use a combination of different herbs.

Quick Tip

Feel free to cut the mushrooms and onions up to 8 hours in advance to save some time at the end of the day when you’re trying to get dinner on the table. Or buy bags of pre-chopped onions and mushrooms to make it even easier on yourself!

Recipe FAQs

Do you saute onions or mushrooms first?

I prefer to saute the onions first. I find that onions are sweeter and more flavorful when they are caramelized, which can take some time. If you start the onions before the mushrooms, they’ll have a chance to caramelize by the time the mushrooms are done cooking.

How long does it take to saute mushrooms?

It typically takes about 6-7 minutes to saute mushrooms over medium heat. If you’re cooking your mushrooms at high heat, it will take 4-5 minutes.

How do you saute mushrooms without them getting soggy?

Mushrooms release a lot of liquid as they cook. This can make them soggy if the liquid is not cooked off. It’s important to cook your mushrooms for long enough so that the liquid can evaporate and the mushrooms can brown. If you find that your mushrooms are not browning, you can increase the heat to high to help the process along.
