Instant Pot Tuna Casserole
I don’t know very many people who didn’t have a tuna noodle casserole in their family’s meal rotation while growing up. We sure did, and it was always one of my favorite meals! Still is.
For this tuna noodle casserole recipe, I have adapted my recipe that I have made for years, and raised my kids on. They all love it. What I found it that it is much better made in the Instant Pot®!

What makes Instant Pot Tuna Casserole better than oven baked?
- Here’s why I think it’s better:
- It cooks much faster than in the oven. Minutes vs an hour!
- No pot of boiling water to deal with. Noodles cook with the sauce.
- One pot! I love a one-pot meal!
- The tuna casserole comes out more saucy and creamy.
- The flavors seems more pronounced.
Can I Add a Crunchy Topping?
Yes you can. See the notes section of the recipe card. But in a nutshell, you can transfer the casserole to a baking dish and add a panko/butter/parmesan topping and broil it.
Or just add crushed potato chips to your serving. Now that’s old school!

How Can I avoid the Burn message?
- That’s always a bummer. The best way to avoid getting the burn message is to follow the recipe carefully.
- Weigh your pasta!: This is the biggest reason people get the burn message when cooking pasta, because the pasta will absorb the liquid. Weighing the pasta is the most accurate way to measure it. You need 1 cup of broth/water to every 4 ounces of dry pasta. You need to be sure that you have enough liquid to create the steam needed to bring the pot to pressure.
- Don’t stir the contents before pressure cooking. Layer the ingredients as directed, but don’t stir until it is done cooking.
- Layer the Ingredients: By not stirring in the thick cream of mushroom soup, you are keeping the thin liquid on the bottom where it can boil and create the steam needed to build the pressure.
I have only had a tiny bit of scorching with this Instant Pot Tuna Casserole recipe, but not enough to give me a burn warning or affect the taste of the tuna casserole at all.

Notes
Avoiding the Burn Warning
It is very important to have the broth-to-noodle ratio correct to avoid burning from not having enough liquid. 12 ounces of noodles needs 3 cups of broth. The noodles will absorb it. So be sure to use the correct amounts of both. If You Want a Crunchy ToppingYou can transfer the casserole to a baking dish and add a ½ cup Panko / 1 Tbsp melted butter / ½ cup parmesan topping (mix those together and sprinkle on top). Then just broil it for a few minutes. You can also just add crushed potato chips to your serving.

5K Stars. Great recipe .I’m a month into using an Instant Pot & this was a great success. Some of the other online recipes I’ve tried I was disappointed with. I will look for a cookbook by you!
5 stars! For some some reason it wouldn’t let me click on a rating. Tried this tonight for dinner and it came out super tasty. Diced up some fresh albacore tuna my fiancé had caught and it worked great. My first time using the instant pot! Thanks for sharing!
Thank you for posting this recipe! It is excellent! I will definitely make this again. I did forget to add the cheese. I poured the casserole into a pan and topped it with the panko bread crumbs before turning around to see the cheese still sitting on the table. Oh well! Next time I will add the cheese!
I give this recipe a 5 star rating. Unfortunately I can’t add the stars above. Not sure if it is on my end or not but this is a great recipe!
This was amazing, so glad I found this recipe.
This site is difficult to leave a message on! However, want to let you know that I made this last night and it was SO DELICIOUS AND EASY!! Brought back memories of childhood. Plan to work my way through all your recipes!!
Hi Dixie, I didn’t realize that the comments are difficult to leave. Can you explain what is the difficult part? I can have my tech team look into it. Thank you for your comment, I’m happy that you liked this recipe!
Just made this tonight and it was absolutely delicious! In only had 1 c of cheddar so used Monterey Jack as well. Very tasty and my kids loved it. Will make this again for sure! Thank you!!
My husband and children loved this dish! so creamy ,noodles weren’t mushy at all .5 stars we will be making this again.
I used mini shell pasta and added the frozen petite peas before cooking. I also only had 1 cup of shredded cheese so I added 3 tablespoons of cream cheese. At 65 years old, I’ve learned what to substitute for a great taste.
Thank you Sandy for giving me recipes for the instant pot for some of the recipes that I used to use with the old school pressure cooker with the pressure valve on the center of the pot lid that made “shooh, shooh. shoosh” noises as it cooked.
And if the pressure got too high the valve could blow off and there would be dinner on the walls, ceiling and floors. It almost made my mother almost swear..
The Instant Pot is sooooo much easier!!
Oh yes, I remember those old school pressure cookers! I’m so glad this recipe worked for you!
How to get the top crusted with flavored bread crumbs?
Add the casserole to a baking dish, sprinkle on the bread crumbs, and broil for a few minutes.
I halved this recipe and cooked it in the mini. Delicious!
