Step 1

In a large skillet over medium-high heat, add the butter, olive oil, lemon juice and vinegar. Stir until the butter has melted.

Step 2

Add the mushrooms to the pan, and the thyme if using. If using a small skillet, you want to aim for one single layer of mushrooms, so cook in batches if need be.

Step 3

Cook, stirring frequently about five minutes, or until the mushrooms soften a little and begin to turn golden.

Step 4

Turn off the heat, season with salt and pepper, serve and enjoy!
