Sauteed mushrooms and onions are super easy and make a delicious side dish. They are so creamy, vegan and gluten free.
I make sautéed mushrooms and onions quite regularly in my house. They're great to add to so many dishes or even great as a side dish to any meal.
I prefer to make sautéed mushrooms and onions without using any butter or cream so they are also vegan and gluten-free. I use extra virgin olive oil as a lighter healthier option and they still turn out nice and creamy!

Ingredients to make Sauteed Mushrooms and Onions
- Mushrooms are of course the hero of the dish! Here I’ve used a mix of Swiss Brown and White Button Mushrooms. You can also add a range of different mushrooms such as portobello and wild mushrooms
- Brown onion works so well with sauteed mushrooms so I love adding them to the mixture
- Garlic because I’m a garlic girl and I love adding garlic to most dishes 🙂
- Olive oil is used to saute the mushroom mixture rather than using melted butter
- Parsley is added at the end for a pop of green colour and freshness. You can also use fresh thyme too
- You can also add a splash of white wine, soy sauce, or worcestershire sauce for extra flavor too. Balsamic vinegar also works great with sauteed mushrooms and onions, but I've kept this as a basic recipe that can be adaptable to most

Tips to Saute Mushrooms and Onions
- Adding a pinch of salt when sautéing the onions helps them caramelise and cook down without burning
- It's always great to use a range of mushrooms for different textures and flavors. Some of my favourite mushrooms are Swiss brown mushrooms, portobello mushrooms, oyster mushrooms and shiitake mushrooms
- Never wash or rinse mushrooms with water as this will make them watery and slimy. Instead, use a damp paper towel and wipe off any dirt to clean them. You can also use a cooking brush too.
- Slice mushrooms approximately the same size in thickness so they cook evenly
- Saute the onions first before adding the garlic, as the onions take longer to cook. Saute them on low - medium heat so they don't burn
- Once the mushrooms are added, increase the heat to high to ensure they saute and don't develop too much water
The onions are sauteed first as they take longer to cook compared to the garlic. The mushrooms are then added last to be sauteed
It's best to firstly not wash the mushrooms as this will make them watery and slimy. Saute the mushrooms on high heat and don't add any salt, as this will make the mushrooms watery. Only season with salt at the end once they have browned
Mushrooms take 5 to 10 minutes to be sauteed, depending on the quantity of course. You'll want them tender with a light char
You can store any leftovers in the refrigerator for up to 3-4 days. I recommend reheating for a couple of minutes in a fry pan for the best flavour rather than microwaving
