Questions

How long does Baked Potato with Tuna Mayo keep?

Refrigerate leftovers within two hours and eat them within three days. Reheat uncovered in a 400 F oven (or an air fryer) for a few minutes to bring the crust back; the microwave softens it.

Can I halve or double Baked Potato with Tuna Mayo?

Yes. As written it serves 2. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubled, split it across two pans and rotate them halfway; one crowded pan bakes unevenly.
