Line a baking pan with aluminum foil. Position an oven rack in the center and preheat the oven to 375 degrees.
Cut the stem and 1 inch off the top of the artichokes. Trim the outer leaves using scissors. Cut the artichokes in half lengthwise. Use a knife to carefully core out the hairs from the center of the artichoke.
In the area where the hairs were, place a garlic clove in each section. Drizzle with olive oil, squeeze the juice of one lemon over the artichokes, and sprinkle generously with salt. Flip the halves over so the cut side is flat on the pan.
Roast in oven for 35 minutes.
When the artichokes are done, transfer them to plates, and serve.
