Heat olive oil or butter in a large skillet over medium heat.

Add the garlic and sauté for 30 seconds until fragrant.

Toss in the sliced mushrooms, spreading them out evenly in the pan.

Cook for 6-8 minutes, stirring occasionally, until the mushrooms are golden and tender.

Sprinkle with salt, pepper, and lemon zest, stirring to combine.

Turn off the heat and drizzle with fresh lemon juice for a zesty finish.

Garnish with chopped parsley and serve warm as a side dish or a light snack.
