This easy sautéed mushrooms recipe is a buttery side dish that goes with everything! It's restaurant quality yet made with simple, everyday ingredients like lemon and parsley.
Add the oil and butter to a skillet over medium-high heat. Once the pan is hot, add the onions, mushrooms, and Italian seasoning. Sauté, stirring occasionally, until the water has been released from the mushrooms & cooked off and everything gets a good sear and is browned. It'll take about 20 minutes depending on the size of your skillet, how thick you cut the mushrooms, etc. Do not rush this step!
Stir in the garlic, Dijon mustard, lemon juice + zest, and parsley, and cook for another minute or two; just long enough to cook out that raw garlic flavor.
Season with salt & pepper as needed, and serve immediately.
Notes
This recipe will go a lot faster if you only want to use 8 oz of cremini mushrooms as the pan won't be as crowded and they will brown faster.
