This Instant Pot version of a 1950s classic casserole features wide egg noodles and tender chunks of tuna in a creamy, cheesy sauce with peas and just a hint of parsley.
I love this one-pot tuna casserole not only for the flavor, but also because of the nostalgia. You simply can't eat tuna casserole without thinking about your childhood! My family never put crushed potato chips on top, but if that's part of your casserole memories than by all means go for it!

Questions About Instant Pot Tuna & Egg Noodle Casserole
Yes, you can, and you'll end up with a deliciously creamy pasta dish. Yum! Just leave out the tuna and follow all other recipe instructions
Yes, you can. Use 12 ounces of elbow macaroni (¾ of a one pound box or bag of dried pasta). Follow the recipe below with this one change: When you add the pasta to the Instant Pot, only add 3 cups of water and cook the elbow macaroni for 6 minutes on high pressure.
Only if you know exactly how much water to add and the correct cooking time for another type of pasta. The 2 minute cooking time and 4 cups of water for 12 ounces of pasta has only been tested for egg noodles.
One pasta shape to try would be this recipe for Instant Pot orzo. Follow the cooking instructions for orzo, then just stir in the ingredients for this tuna casserole.
Classic tuna casserole is often baked with either breadcrumbs or crumbled potato chips on top. When you finish cooking this recipe, you can transfer it to a casserole pan and add one of these toppings before serving.
I like to use "solid" canned tuna for this recipe, so that the dish has larger pieces of tuna in it. This is different than "chunk" tuna, which has very small/shredded pieces. The label on the can should indicate "solid" or "chunk." Here's a guide from Good Housekeeping about the different types of canned tuna.
I also used water-packed, because this dish is rich enough and doesn't need any added oil. If you'd like a recipe for oil-packed tuna try Tuna Pesto Pasta.
Yes, canned tuna is already cooked and ready to eat. That's why you can add it to this recipe after the pasta has cooked.
Yes, you can freeze the cooked casserole in a sealed container or you can wrap a casserole dish with several layers of plastic wrap. Defrost overnight in the refrigerator. To reheat tuna casserole, use the microwave or reheat in the oven in a foil-wrapped dish at 350 F. Add a drizzle of milk or half an half as it reheats to loosen up the noodles and sauce.
