Trim them well: Be sure to remove the tough outer leaves, trim the stems, and scoop out the fuzzy center so the artichokes are easier to eat after roasting.
Use lemon right away: Rubbing or brushing the cut artichokes with lemon helps keep them from browning while you prep.
Cover tightly while roasting: Covering the pan with foil helps trap steam so the artichokes become tender instead of drying out.
Check the base for doneness: The artichokes are ready when the thick base is tender and can be pierced easily with a knife.
Serve warm: Roasted artichokes taste best warm, especially with a dipping sauce or extra lemon on the side.
