I used 4 large Artichokes for this recipe.
Preheat the oven to 425
First cut the tops off each one as well as the bottom of the stem. The drizzle with olive oil. On the top of the artichoke rub with ground garlic paste (the kind that you can get in the jar at any supermarket)Cut 4 large pieces of Aluminum foil and get a glass baking dish ready. Place each of the artichokes in a piece of the foil with a garlic clove and second drizzle of olive oil. Wrap tightly and let cook for 1 hour and 15 minutes.
Take out of oven and unwrap carefully. Cut each artichoke in half and lay in baking dish. Add 2 pats of butter for each half and sprinkle with Parmesan cheese. Place back in oven for 10 minutes. Then turn on broiler for until desired browning is reached. Serve hot.
