If you don’t want to use rigatoni, stick with sturdier pasta such as penne, fusilli or farfalle.
There is no need to thaw the corn or the peas ahead of time!
Bring your milk to room temperature before making the bechamel sauce.
If your creamy white sauce is too thick, you can thin it with a bit of milk.
Swap out the peas and corn for any of your favorite veggies. For larger vegetables, cut them into bite sized pieces.

Frequently Asked Questions

Should I use tuna in water or tuna in oil?

The kind of canned tuna you use is really a personal preference. Tuna in oil is flavorful and has a lovely texture, while tuna in water has a milder flavor and is lower in calories and fat.

Why is my tuna and noodle casserole so dry?

Pasta absorbs moisture, so a lack of moisture can cause a dry casserole. To prevent this, add a bit of milk if your bechamel sauce is thick. You can also cover the casserole for the first 20 minutes of cooking.

Do I need to precook pasta for casseroles?

Yes. The pasta should be precooked and drained before mixing with the other ingredients. We recommend that you cook the pasta to al dente as it will continue cooking while the casserole bakes.

How do I store and reheat cheesy tuna bake?

Store your leftovers in an airtight container and eat them within 3 days. Reheat in the microwave for single portions or pop the casserole in the oven for about 20 minutes or until heated through.

Can I freeze easy tuna noodle casserole recipe?

Yes! This casserole freezes beautifully. Tightly wrap the whole unbaked casserole and pop it in the freezer for up to 2 months. Thaw overnight in the fridge and bake as directed.
