Does anyone have a great recipe for this? Need something I can make a day in advance for a party and cook through/warm up in the oven on site. I was thinking of the recipe below, but don’t know if it’s a possible make-ahead dish since the recipe doesn’t give that option. Happy to entertain your favorite recipes for creamy, dreamy make-ahead Mac and cheese. Thank you!

Does anyone have advice on how to turn hasselback potatoes into a stunning potluck dish? I live an hour from the party, so don’t want to complete the dish at home, only to have it sit for 3 hours until it’s actually consumed. Will have access to an oven onsite for 25 minutes at most. I want to do a “fully loaded” version, with cheese, bacon, sour cream, etc. But will forgo the plan for another version that will work better under the circumstances.
