Tips & Substitutions
For a creamier texture, consider adding a splash of milk or cream to the casserole mixture before baking. You can also substitute the tuna with canned salmon or shredded chicken for a different flavor profile. Fresh herbs like dill or parsley can add a nice touch. If you prefer more veggies, add in some chopped mushrooms or spinach to boost nutrition.
Serving Suggestions
This Creamy Seaside Casserole pairs beautifully with a crisp green salad or Sea Slaw for a refreshing contrast. You could also serve it alongside garlic bread or steamed vegetables for a complete meal. For added flavor, consider topping with grated cheese during the last few minutes of baking to create a bubbly, golden crust.
Storage & Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the oven at 350°F for about 20 minutes, or until heated through. You can also microwave individual portions for a quick meal, but be sure to cover it to retain moisture.

Frequently Asked Questions
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a day in advance. Just cover it tightly and refrigerate until you're ready to bake. When you're ready to serve, you may need to add a few extra minutes to the baking time since it will be cold from the fridge.
What can I substitute for Velveeta shells and cheese?
If you prefer a homemade option, you can use cooked pasta with a cheese sauce made from cheddar cheese, milk, and butter. This will give you a similar creamy texture that works well in the casserole.
Is it possible to make this dish gluten-free?
Absolutely! You can use gluten-free pasta in place of the regular shells. Make sure to check that all other ingredients, like mayonnaise and canned goods, are also gluten-free to ensure the dish meets your dietary needs.
