Halve the tomatoes, remove the seeds if necessary. Spread 6 tablespoons of olive oil in a baking dish, place the halved tomatoes in the dish with the skin side down.
Heat the remaining 2 tablespoons of olive oil in a pan and roast the sliced garlic until golden. The garlic must not turn black, then it becomes bitter.
Spread the roasted garlic over the tomatoes, season with salt and freshly ground pepper. Finely chop the thyme and rosemary and pour over the tomatoes as well. Cook in a preheated oven at 180 degrees for around 15 minutes.
Tastes warm and cold with grilled or freshly baked bread and is also very, very tasty as an antipasti.
