Ingredients

You can make this Instant Pot tuna pasta using pantry staples and ingredients from your fridge and freezer:

• Canned tuna – I use albacore tuna packed in water
• Egg noodles — You can use yolk free pasta if you have it
• Chicken broth — for flavor, or vegetable broth
• Spices — Salt, pepper, garlic powder, dried onions or onion powder and herbes de Provence
• Cheddar cheese — or cheddar blend, shredded
• Heavy cream — or heavy whipping cream
• Frozen veggies — I use a blend of frozen peas and carrots or mixed veggies

How to Make Instant Pot Tuna Casserole

Since the tuna is already cooked, you basically just dump the dry pasta and everything into the electric pressure cooker and press start. But, I’ll walk you through this simple recipe, and you can find step-by-step full directions in the printable recipe card.

First step — Add the uncooked egg noodles first, then some low sodium chicken broth, chicken stock or vegetable broth.

You could also use water if you want. I just like the extra flavor you get from using broth.

Next, add your drained tuna and the seasonings. I love adding herbes de Provence seasoning blend when I make cook with chicken or turkey, so I used some here. If you can’t find it, that’s fine.

It just adds a little extra flavor. You can also use Italian seasoning or dried parsley or just the basic salt, pepper, garlic and dried onions.

You’ll add the cheese and heavy cream after pressure cooking. This helps to avoid getting the burn notice and prevents the dairy products from curdling.

Cooking Time

Egg noodles cook faster than other pasta. So, pressure cook the tuna casserole for 2 minutes on high pressure followed by a quick release.

If you need to use penne, shells, macaroni or other thicker dried pasta, you’ll want to increase the cook time to 4 minutes.

After pressure cooking, stir in mixed vegetables, heavy cream and shredded cheese. I used a cheddar blend  here, but I like using extra sharp cheddar, colby jack or Monterey jack, too.

The tuna mixture might look like it has too much liquid, but don’t worry. It will definitely thicken up as it cools down. You can turn off the keep warm setting, and let it sit in the pot or transfer to a serving bowl or dish if you want.

Tender noodles, flaky tuna and vegetables in a perfectly seasoned creamy sauce. This is definitely the best instant pot tuna casserole out there!

And that’s all, folks! Time to dig in and enjoy this super cheesy one pot meal. You don’t even need a side dish, although we love to serve dinner rolls with this delicious family meal.

Variations

If you have the Duo Crisp, Ninja Foodi or mealthy crisplid or any pressure cooker that crisps with an air fryer lid, you can top this easy Instant Pot tuna casserole with a crispy topping, such as bread crumbs, cracker crumbs or crushed potato chips. Then, spritz a little cooking spray or add melted butter, and crisp it up before serving.

Or, transfer the cooked tuna casserole to a baking dish (grease with olive oil or butter), add toppings, and bake until the top is golden brown and the casserole is bubbly. You can do this in your air fryer toaster oven, as well.

If you want to add cream of celery soup, cream of mushroom soup or any cream soups to tuna noodle casserole in Instant Pot, you can add it before pressure cooking. Don’t stir everything together until after pressure cooking.

How to Store

When refrigerated in an airtight container, this easy tuna casserole should last for 3 to 4 days — if it isn’t gone by then. Ours is usually gone by the next day! You can always freeze leftover tuna casserole for longer storage.

Reheat this classic casserole in the microwave.

Cooking Tips

Be sure to add the cream and cheese after pressure cooking to prevent getting the burn notice.

Egg noodles cook faster than other pasta — 2 minutes. If using a different type of pasta, cook for 4 minutes. Always use a quick release or controlled quick release with pasta.

If you want to make tuna casserole with mushroom soup, add the soup before pressure cooking, but don’t stir everything together. You can it after cooking, as well.

The casserole will thicken as it cools down and absorb the extra liquid. No need to thicken the tuna casserole unless you want to add more cheese.
