- Butter: Unsalted or salted. If using salted butter, reduce the added salt.

How to make Sautéed Mushrooms and Onions
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
- Melt the butter and heat the olive oil over medium-high heat in a large skillet or pan. Stir in the Worcestershire Sauce.
- Add the mushrooms and sauté until golden brown. Toss in the onions and cook until the edges brown and become translucent.
- Reduce the heat to low and add the minced garlic.
- Salt and Pepper to taste; if desired, sprinkle with chopped fresh parsley or thyme.
Preparation Tips
- To clean mushrooms, wipe the mushrooms with a damp paper towel to remove the dirt, and dry them well with a paper towel.
- Do not burn the melted butter. The key is to stay close by and have everything prepped and ready to go.
- Cook mushrooms over medium-high heat. They release a lot of moisture, so to brown properly, they must be cooked over fairly high heat and stirred frequently to prevent burning.
- For optimal flavor, add the garlic during the last minute of cooking. Reduce the heat to low and stir frequently. Garlic burns easily and tastes bitter when it burns.
- Top with fresh herbs like parsley, rosemary, and thyme.
Ways to serve Sautéed Mushrooms and Onions

I couldn’t agree more! Sautéed mushrooms and onions are always a great addition to any meal, and this recipe was particularly delicious. The fact that it only requires six ingredients and comes together quickly is definitely a plus, especially on busy weeknights. I served it with some grilled t-bones and mashed potatoes and it was a spectacular meal.

I am often making something similar just with tomato sauce. But I stopped using garlic. Definitely need to use both garlic and onions, it tastes so much better.

I love making this! I like having it with steak or with chicken sometimes.

Mushrooms are not my thing, but I love grilled onions. What do you think would make a good substitute, in this recipe, for the mushrooms?
