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.

This was GREAT! Thank you for your expertise and for sharing! I thought I was in trouble because I instinctively stirred the noodles and it HIT me that I wasn’t supposed to! 😂 So I was very careful to follow the rest of the recipe closely. NO I DIDN’T BURN IT!!! My saving grace was my non-stick ceramic pot. 😊
PS I wasn’t able to rate the recipe. It wasn’t responsive to my touch, but I would have rated it 5 stars!
If I could give your recipe 50 stars, I would! I, too, am a senior and remember being a kid and loving this stuff. I hadn’t bothered making it in the traditional way for fear of messing it up! Thank you and thanks to Instant Pot for revolutionizing my cooking world!
I’m so pleased to read your review! This is why I love my job! To know I helped you make a great meal is awesome!
I have the 10 qt crockpot express. How can I adjust this for this pot.
You should be able to follow this recipe.
Best tuna noodle casserole I’ve ever made and that’s a lot. I did add chopped red and green pepper, used whole milk instead of half and half. It came out perfectly at 3 minutes. I topped mine with garlic croutons and plain chips and cold butter crushed in my Nijana…. Then broiled. Thank you for sharing .
5 stars!!! I cooked this casserole last night and it was absolutely delicious!
Shouldn’t Step #6 also say don’t stir? Someone on Facebook just reported getting the burn sign for this recipe.
Yes. That’s why I say to spread the soup over. One of the reasons people get a burn message is by not weighing the pasta, and not measuring the ingredients.
Thank you for the clarification, Sandy. Love your recipes! So easy to convert to 3 qt., if conversion is even needed at all. Plus, it’s good to see your 3 qt Mini list of recipes is getting longer! Hope you and your family are okay as I know you are near a “HOT“ area. Please take care! Your “neighbor” in the Portland Metro Area.
This was yummy. We got the burn message even though I weighed the noodles and followed all the directions. We couldn’t see the timer due to the burn message but we went ahead and guessed about the time, released the steam which was minimal and it came out just right. A little was stuck on the bottom but not “burned” and the noodles were perfect,. Also, I am lactose intolerant for liquid milk products so we used Coconut Creamer for the half and half. Yummy!
I made this tonight ant was great! Everything came out perfect. Didn’t have peas (wish I did) but no matter. I also had 1 can mushroom and one can celery. Thanks for the easy recipe!!!
Very tasty! It was a hit with my Hubby! Perfect dish for Ash Wednesday.
Thank You! 5 stars!
Can you use fresh dill? If so, when should we add it?
Thanks!!!
Yes, I would some before cooking, and some after!
5 stars all the way. Couldn’t click on star rating but 5 stars it is. The hubby and the sun are both exceedingly pick eaters and they both devoured it. Love the idea of not adding the soup to the bottom but pouring it on top. Whole family loved it
