Delicious Variations

- Swap The Noodles – Ziti and egg noodles are great, but any type of pasta can work in a pinch. Use what you have in your pantry.
- Replace The Tuna – Feel free to use canned salmon instead. You can also make this recipe with canned chicken.
- Use Different Soup – Cream of mushroom soup can be replaced with cream of chicken or cream of celery soup.

Prep and Storage
- Prep Ahead – Precook the noodles according to package instructions, then store in an airtight container in the fridge until ready to assemble the casserole.
- Store – Leftover casserole can be refrigerated for up to 3 days when stored in an airtight container.
- Freeze – Follow the handy tips below on how to freeze this.
- Let it cool completely before covering with foil and then freezing.
- Alternatively, freeze before baking. Be sure to thaw it fully before baking, so it cooks evenly.
- Store in the freezer for 3 months.
- Thaw and Reheat – Thaw the cooked frozen tuna casserole in the fridge overnight. Bake it at 400 degrees F / 200 degrees C until it has been heated through.

FAQs
This casserole is perfect for freezing. For smaller families, divide the casserole in half, baking half now and freezing the rest for later. Freeze before or after baking, thaw overnight inside the fridge, then cook and serve.
There are several things that can cause a dry casserole. To solve this problem, follow the recipe carefully, so there is enough moisture in the casserole. Secondly, cover the casserole with foil during the first half of the baking time. Finally, make sure you aren’t using a casserole dish that is too large.
Canned tuna makes this recipe affordable and easy. With so many varieties of tuna like solid white albacore tuna, light tuna, packed in water and packed in oil, you may not know which to use. The type of tuna you select is really a personal preference. Be sure to drain the tuna before adding to the recipe. If using tuna packed in oil, rinse the tuna in a strainer before using.
