FAQs
Can I use fresh tuna instead of canned tuna?
While canned tuna is convenient and well-suited for this casserole, you can use cooked fresh tuna chunks. Just make sure they are fully cooked and drained of excess moisture before mixing.
Is it possible to make this recipe ahead of time?
Yes, you can assemble the casserole a day in advance. Cover and refrigerate it, then bake it fresh when ready. You may need to add a few extra minutes to the baking time since it will be cold from the fridge.
