❓ Frequently Asked Questions About Tuna Fish Casserole
Q: What type of tuna should I use?
In this recipe, we recommend using canned light tuna in water. This type of tuna is lower in mercury than other types, making it a safer choice for families with young children.
Q: Can I use fresh tuna instead of canned?
While you can use fresh tuna if you have access to high-quality sources, canned tuna is actually preferred in this recipe due to its convenience and consistency.
Q: How do I prevent the casserole from becoming too dry?
To avoid dryness, make sure to not overbake the casserole – aim for an internal temperature of 165°F (74°C). Also, don’t forget to add the cream of mushroom soup mix as directed – this will help keep the casserole moist and flavorful.
Q: Can I substitute the mayonnaise with something else?
You can swap out the mayonnaise with plain Greek yogurt if you prefer – just keep in mind that the flavor will be slightly different.

To store leftover casserole, let it cool completely before refrigerating or freezing – then reheat when ready by following these reheating instructions below.
