Preheat the oven to 375 degrees F.
Rub the inside of 6 ramekins with the butter and then season with the thyme, distributing both equally amongst the ramekins. Add 2 eggs to each, season with salt and pepper. Place the ramekins in a baking dish, and pour water into the baking dish until it is halfway up the sides of the ramekins. Carefully place the baking dish in the pre-heated oven. Bake eggs for 15 minutes, or until set and golden on top. Eat and enjoy!
