What kind of pasta should I use with tuna casserole?

In this recipe, I used bowtie pasta, but you may use whatever you have on hand. Egg noodles are a common favorite for tuna casseroles.

If using egg noodles, I recommend pressure cooking for only 1 minute.

What veggies can I add to my tuna casserole?

In this recipe, I added fresh carrots and mushrooms to the pot during the pressure cook time. Later, I added canned peas (drained). You can use any combination of fresh, frozen or canned veggies.

If you are using fresh vegetables, add them prior to pressure cooking.

If you are using frozen or canned, add them after pressure cooking and sauté to preferred temperature.

Can I freeze tuna casserole?

Yes, be sure to place in an air-tight freezer bag. Store in the freezer for up to three months. Also, you’ll want to thaw in the refrigerator or in a pot of cold water prior to re-heating.

What can I serve with tuna casserole?

If you’re feeling fancy like Martha Stewart, add on some bread crumbs or extra cheese. I like adding Tony’s cajun seasoning to mine.

I like to serve my casserole with a nice side salad.
