Preheat oven to 400°.

Fill a large pot with water and squeeze juice from 1 lemon in it.

Cut 1" off the artichoke stem and then place in lemon water.

Cut 1" off of the top of the artichoke and then place in lemon water.

Trim each individual artichoke leaf with kitchen scissors and then place in lemon water.

Slice the artichoke in half long-ways and then place in lemon water.

Use a knife or grapefruit spoon to remove the "choke", aka the hairy part of the artichoke.

Drizzle a large baking dish with olive oil and then place artichoke in the dish; add garlic, thyme, the other lemon (sliced), and salt and pepper.

Wrap each artichoke half with foil, place face down in the baking dish and bake for 45 minutes.

Once roasted, carefully remove from oven and wait 5 minutes or so before removing foil and enjoying with extra olive oil, butter and/or parmesan cheese.
