Make-Ahead and Storage

You can prepare this casserole up to a day in advance of when you want to serve it. Prepare everything and assemble all the components in the pan, except the breadcrumb topping. Cover the pan tightly and refrigerate until about 30 minutes before you're ready to serve. Then simply preheat the oven, sprinkle on the topping, and bake as directed.

If there are any leftovers, pack them into a storage container with a tightly sealing lid and use within two days.

Frequently Asked Questions:

Tuna Casserole

Rachel Marek

What kind of tuna is best for tuna casserole?

There is more to canned tuna than meets the eye. In addition to just water or oil-packed, consider the many different varieties, textures, and preparations of tuna; ethical and environmentally responsible fishing and packing practices; and how you intend to serve the tuna. Some of the highest quality (and most expensive) tuna packed in high-quality olive oil is best saved for simple preparations like salads where there aren’t a lot of other ingredients covering up the flavor of the tuna. More affordable water-packed and oil-packed options are just fine for tuna casserole. Learn lots more in our Canned Tuna Guide.

Why is my tuna casserole dry?

In addition to pasta, tuna, and vegetables, make sure you have enough sauce to bind it all together and give it moisture.

How do you reheat tuna casserole without drying it out?

Whether you’re using the microwave or the oven, keep your leftovers covered during reheating. Once it’s hot, you re-crisp the topping if you wish by pop it under the broiler for a minute or two.
