Frequently Asked Questions
Can I use fresh potatoes instead of paring them?
Yes, you can use fresh, unpeeled potatoes. Just make sure to slice them thinly to ensure they cook evenly. You may need to adjust the cooking time slightly when boiling them before layering.
Is there a substitute for tuna in this recipe?

Can I make this casserole ahead of time?
Yes, you can prepare the casserole a day in advance. Assemble it as directed and store it covered in the refrigerator. When ready to bake, allow it to sit at room temperature for about 30 minutes before placing it in the oven to ensure even cooking.
