Brought these to the summer potluck and three people followed me to my car asking what was in them.

best crisp edges: The slow cooker makes the potatoes tender, but the quick broil is what gives them that craveable crisp-cheese finish. Do not skip that step if texture is your priority.

Keep them warm for serving: If you’re taking these to a gathering, leave them in the warm slow cooker setting until just before serving, then broil in batches if needed once you arrive, provided you have oven access.
