Place all ingredients into an oven proof dish and fully submerge with olive oil. Season generously with salt. Mix all the ingredients together with your hands or a spoon. Bake for 1 hour.
Separate the olive mixture from the oil and reserve the oil in a jar to be used in any recipe that calls for olive oil. It will have a lovely olive, lemon and garlic infused flavour.
Drizzle the olives with a little of the oil they were cooked in and an extra sprinkling of thyme. Serve while warm on their own or with some whipped feta and ricotta and fried bread.
