Experiment with different herbs like oregano or basil if thyme and tarragon aren't available. This dish also works well with other protein options; try adding shrimp for a twist on classic seafood recipes.

Frequently Asked Questions

Can I use fresh tuna instead of canned tuna?

Yes, you can use fresh tuna, but make sure to cook it thoroughly before adding it to the casserole. Fresh tuna will need to be seared or poached first, then flaked into the mixture. This will give a wonderful texture and flavor, enhancing the overall dish.

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole up to the baking step and store it in the refrigerator for up to 24 hours. When you're ready to bake, simply pop it in the oven. This makes it a great option for meal prep or entertaining guests.

How can I make this casserole vegetarian?

To make a vegetarian version, omit the tuna and replace it with cooked vegetables like mushrooms, zucchini, or bell peppers. You can also add a can of chickpeas for protein. The recipe will still be delicious and satisfying without the seafood.
