Frequently Asked Questions

Can I use fresh fish instead of canned tuna?

Yes, you can use fresh fish, but you'll need to cook it beforehand. Poach or bake the fish until fully cooked, then flake it and incorporate it into the casserole. Adjust the cooking time as fresh fish may require less time to bake compared to the casserole's overall baking time.

What types of cheese work best for topping?

Cheddar cheese is a classic choice that melts well and adds great flavor. However, you can experiment with other cheeses like Monterey Jack, Gruyère, or even a blend for a more complex taste. Just make sure to use a cheese that melts nicely for that perfect golden topping.

How can I make this dish gluten-free?

To make the casserole gluten-free, substitute the all-purpose flour with a gluten-free flour blend or cornstarch. Additionally, ensure any canned products, like the tuna and broth, are labeled gluten-free. This way, you can enjoy the same comforting flavors without gluten.
