Why You'll Love This Recipe
- No canned cream of mushroom soup!
- A classic tuna casserole made easy with the use of an instant pot!
- Makes great leftovers! The flavor is even better the next day!
Ingredient Notes
- Tuna - I always use the tuna packed in water. This recipe calls for 2 cans however you may add an extra can of tuna if you like.
- Peas - You can use frozen peas, canned peas or steamed fresh peas.
- Egg Noodles - I use the medium sized egg noodles. If you can't find the medium ones I would opt for the small size over the large ones.
- Mozzarella Cheese - You can use just shredded mozzarella or you can get the different blends of shredded white cheeses like an Italian cheese blend. I recently use a mozzarella provolone cheese blend that was really good.
- Ranch Seasoning - You do not want to leave the ranch dressing mix out. If you do this tuna casserole recipe will turn out very bland.
Couple Things You'll Need
Step by Step Instructions
- Dump 8 ounces of medium sized egg noodles into the inner pot of a 6 quart instant pot.
- Sprinkle one packet or 3 Tbs of Hidden Valley Ranch Dressing Mix over the noodles.
- Pour the chicken broth aka chicken stock, over the dressing mix and dry pasta.
- Secure the instant pot lid and cook at high pressure for 4 minutes.
- When the 4 minutes is up do a quick release of the steam but allow the pot to stay on the keep warm setting.
- While that is cooking, cube the cream cheese. While it's ideal for it to be room temperature, if it's cold from the fridge the smaller the pieces of cream cheese the better as the hot pasta will be able to better melt it.
- Open and drain 2 cans of tuna fish.
- Warm a cup of milk.
- Shred the cheese.
- Carefully open the insta pot lid after the quick release of the steam.
- Add the cubed cream cheese, canned tuna, warm milk, shredded cheese and the peas.
- If using frozen peas there is not need to thaw them first.
- Use a wooden spoon to stir the contents of the pot together.
- Re-secure the lid on the instant pot and allow to sit while on the keep warm setting for 10-15 minutes.
- Release any steam that may have built up and carefully open the lid.
- Give the creamy tuna casserole a stir and serve!
- If you want a crispy topping feel free to add crushed potato chips to the top of the noodles.
- Fresh parsley makes an excellent garnish!
- Store leftover tuna casserole in an airtight container in the fridge.
Recipe FAQs
If stored in an airtight container it should be good for 2-3 days.
This isn't a recipe that I particularly recommend freezing because the quality of the casserole wouldn't be the same once thawed. The taste should be fine but the noodles may not fair well. If you choose to freeze this tuna noodle casserole just make sure it's completely cool before spreading into a freezer safe dish and sealing well. Thaw before reheating. This should be good in the freezer for up to 3 months.
A fresh green salad, dinner rolls or perhaps some garlic bread go great with this classic casserole!

Will I need to add more broth if doubling up this recipe?

Yes 🙂

I made this last night because I wanted something quick and easy. I followed the recipe exactly as written, no change in ingredients and only the addition of peas and carrots. It was so easy! And delicious! I will make this again because I always have those ingredients in my pantry. Thanks for posting a recipe for a quick and tasty meal that satisfies. I wonder how it would taste using canned chicken instead of tuna? Love my Instant Pot.

You’re welcome! I think it was just taste good with canned chicken.

Not sure what happened. I follow the directions to the letter (I did not have curly egg noodles so I used straight ones). When I opened my insta pot I had tuna noodle soup! I tried to cook it down a bit - that only resulted in a horrible stuck on mess on the bottom of my pot. Finally spooned it out into a cake pan and baked off the excess moisture. The flavor was fabulous and I WILL definitely try it again.

I am so sorry that happened. I have heard that flat noodles have a tendency to clump and burn. Than would also explain the extra liquid. Definitely, use the curly noodles next time.

I made this the other day and it was my first time trying pasta in the instant pot. I was skeptical at first because the dry pasta was not fully submerged but it all worked out. I followed your recipe exactly except I put 1 can of tuna. When I used to make Tuna/hamburger Helper I would also halve the amount of meat that it called for.
As for future meals I will omit the mozzarella or only put a little in. I found that it left a bitter aftertaste. And I liked the creaminess that it already had from the milk and the creamed cheese.
Thank you for taking the time to post this! I love my InstantPot!!
