Frequently Asked Questions
Can I prepare the casserole in advance?
Yes, you can prepare the casserole up to a day in advance. Assemble the stuffed potatoes, cover them tightly with foil, and refrigerate. When ready to bake, simply remove the foil and bake as directed, adding a few extra minutes if needed.
Can I use fresh tuna instead of canned?
Absolutely! Fresh tuna can be used instead of canned. Just cook it thoroughly, flake it, and mix it into the casserole filling. Keep in mind that fresh tuna may have a slightly different texture, but it will add a fresh flavor to the dish.
What can I substitute for olives?
If you're not a fan of olives, you can omit them or replace them with capers for a briny flavor. Alternatively, diced pickles or artichoke hearts can also work well, adding a unique twist to the filling.
