Clean the mushrooms with a damp cloth and slice them evenly.
Heat olive oil in a large skillet over medium heat.
Add butter to the pan and let it melt.
Once the butter is melted, add the sliced mushrooms.
Spread the mushrooms in a single layer for even cooking.
Cook for about 5 minutes without stirring to allow browning.
Add minced garlic and stir to combine with the mushrooms.
Continue cooking for another 5-7 minutes, stirring occasionally.
Season with salt and pepper to taste.
Remove from heat and garnish with fresh herbs before serving.
