Place a large skillet over medium heat and add 1 tablespoon of olive oil, swirling to coat the surface. When oil shimmering and fragrant, add the sliced mushrooms in an even layer. Cook for 5-7 minutes, stirring occasionally, until mushrooms are golden brown and have released their moisture, with edges caramelized.
Add the minced garlic and dried thyme to the skillet. Stir continuously for about 1 minute, until the garlic becomes fragrant and slightly golden, ensuring the herbs are evenly distributed.
Reduce heat slightly and cook for another 3-4 minutes, allowing the flavors to meld and mushrooms to become tender and juicy. Season with salt and black pepper to taste, stirring to combine.
Once done, remove the skillet from heat and transfer the mushroom mixture to a serving dish. The mushrooms should be browned, juicy, and fragrant, with a slight caramelized surface.
Garnish with additional herbs or a drizzle of olive oil if desired. Serve hot as a main or side dish.
