Tips & Substitutions
For a creamier sauce, consider adding a splash of white wine or using half-and-half instead of milk. If you don't have tuna, canned salmon or shredded chicken can work as a substitute. For added flavor, you can mix in some grated cheese with the sauce or layer in some cooked spinach or mushrooms for extra texture. Always taste and adjust seasoning to your liking.
Serving Suggestions
Scalloped Tuna is hearty enough to be a main dish, but it pairs wonderfully with a simple green salad or steamed vegetables for a balanced meal. You could also serve it alongside crusty bread to soak up the creamy sauce. This dish is perfect for gatherings and can be a comforting option among other seafood recipes like Baked Trout Supreme.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the dish with foil and warm it in a 350°F (175°C) oven until heated through, about 15-20 minutes. You can also microwave individual portions, but be cautious to avoid overcooking the potatoes.

Frequently Asked Questions
Can I use fresh potatoes instead of pre-sliced ones?
Absolutely! If using fresh potatoes, make sure to slice them thinly and soak them in cold water to prevent browning. You may need to adjust the boiling time to ensure they are tender before layering them in the dish.
What can I substitute for prepared mustard?
If you don't have prepared mustard, you can use Dijon mustard for a similar tangy flavor, or even a bit of mayonnaise mixed with vinegar as an alternative. Just keep in mind that it will slightly alter the taste of the sauce.
Is there a way to make this dish gluten-free?
Yes, you can easily make this dish gluten-free by substituting the all-purpose flour with a gluten-free flour blend or cornstarch. Ensure that the canned tuna and mustard you use are also labeled gluten-free to avoid any allergens.
