How to make this recipe
Instant Pot tuna casserole makes dinner a breeze in one pot! Enjoy these step-by-step photos, or skip down to the printable recipe below.
Step 1. Place uncooked egg noodles in the Instant Pot. Place tuna, peas, carrots, mushrooms, and onion on top of the noodles. Do not stir the ingredients.
Step 2. Add chicken broth to the cooker. Press ingredients down to submerge noodles in the broth. Close the lid, turn pressure valve to the 'Sealing' position, and pressure cook for 1 minute followed by a 10-minute natural pressure release.
Step 3. Carefully turn the pressure valve to the 'Venting' position to release any remaining steam. Open the lid. Heads up, it's a little unsightly at this point. Add milk and cheeses. Stir to incorporate. Cover and rest as needed to melt the cheese.
Step 4. Serve and devour!

Ingredients
- 6 ounces Uncooked Egg Noodles, (about 3 cups)
- 1 (5-ounce can) Tuna, drained
- 1 cup Frozen Peas, thawed
- 1 medium Carrot, diced (about 1 cup)
- 4 ounces Mushrooms, sliced (about 1 cup)
- 2 cups Chicken Broth
- 2 tablespoons Dried Onion Flakes, or ¼ cup diced raw onion
- ¼ teaspoon Sea Salt
- ⅛ teaspoon Black Pepper
- 2 tablespoons Milk, or heavy cream
- 4 ounces Cheddar Cheese, shredded (about 1 cup)
- ½ cup Parmesan Cheese, shredded or grated
Optional toppings
- Lemon (zest and juice)

- Place EGG NOODLES in the Instant Pot.

- Pour in CHICKEN BROTH. Do not stir the ingredients, but DO press ingredients down to submerge the noodles.
- Secure the Instant Pot lid, close the valve seal, and cook on manual HIGH pressure for 1 minute (yes, only one minute), followed by a 10-minute natural pressure release (NPR).Please do not deter from this instruction set if you want perfectly cooked noodles.
- After the 10-minute NPR, carefully turn the pressure valve to release any remaining steam. Carefully open the lid. (It won't look very pretty at first.)NOTE: You'll see a small amount of excess liquid, which is natural and helps incorporate the cheese. It will also be absorbed by the noodles within minutes.
- Add MILK, CHEDDAR CHEESE, and PARMESAN CHEESE. Gently stir to incorporate. Cover and rest as needed to melt the cheese.
- Serve warm with optional toppings.
- To store, allow tuna noodle casserole to cool completely and refrigerate in an airtight container up to 5 days or up to 90 days in the freezer.

Claire says
I was wondering if I could use chickpea pasta (small shells or penne) instead of the egg noodles, and if I should adjust the time?
The Kitchen Girl says
Hiya, others have reported using chickpea pasta without adjusting the time. Keep in mind that different brands use different flours, so you may need to do some testing. Please do let me know how it goes. Thanks and enjoy!
Claire says
I used a box of Banza corkscrew pasta with no changes and it worked great! Thank you!
Hilary says
Really good I have to admit I unsure as I made it but it was delicious comfort food Than you
The Kitchen Girl says
Well that's perfect! So glad to inspire ... thanks so much!
Loretta Russell says
I am going to try tuna casserole. Sounds delicious!
The Kitchen Girl says
Yay Loretta! Let me know if you have any questions. We just made it a few days ago ... absolutely love this recipe for convenience and comfort 🙂 Enjoy!
Lisa says
I've made this using tuna several times. Fast, easy, and yummy. My parents and I really enjoy it. My husband will eat it, but doesn't love tuna. My kid hates tuna and refuses to touch it.
So tonight I used a can of chicken. I always increase the carrots. Added one stalk of chopped celery, and a sprinkle of thyme & garlic powder.
He says this is much better than tuna. Kid agrees (even though she's never tried the tuna!). I still prefer tuna for when I visit my folks, but this is a better choice for my husband and daughter.
Thanks again for a great recipe!
The Kitchen Girl says
Aww you're so welcome and yep, canned chicken is perfect in this too. I love it both ways 🙂 So glad you're enjoying it!
Mary says
This was absolutely delicious. I made it for my parents and my sister and they devoured it. I added an extra can of tuna, thawed peas and carrots (added at the end), and part low-fat cheese mixed with extra sharp cheddar and parmesan. (I didn't use more cheese than the recipe called for and that was a perfect amount! The end result was very creamy.) I added fresh crushed garlic, fresh onion, and a little sprinkle of Bay Seasoning and red pepper flakes and a squeeze of lemon - which took it to a whole other level. Also, I used whole wheat rotini pasta and kept high pressure for 2 minutes - perfect! This will be made again many times.
The Kitchen Girl says
Awesome Mary! I'm so glad you enjoyed it. Sounds like you you really did take Instant Pot tuna casserole to a new level. Love the Old Bay add-in...great idea! I really appreciate your feedback and review. Thanks so much!
Jill Wyatt says
Very good!! I didn't read the notes until I already started my pot, so my frozen peas and carrots were already in the pot. Not sure it mattered cause it turned out great! Will definitely make again.
The Kitchen Girl says
Yay! I'm so glad you enjoyed it and thanks so much for taking the time to leave feedback 🙂
Marcy says
Made this tonight and it was delicious! I didn’t think tuna casserole in the Instant Pot could be as good as in the oven, but I was wrong. I also liked that it didn’t use creamed soup and still turned out creamy.
The Kitchen Girl says
Awesome, Marcy ... I'm so glad you tried it and were so pleasantly surprised 🙂 And yep, I tested this recipe many times before getting the consistency just right. I'm happy you enjoyed. Thanks!
Alexa says
If I wanted to triple the amount of tuna but leave the same amount of pasta, how should I modify this recipe - would the broth amount stay the same? I assume I could just add some extra veggies and cheese to account for the extra volume.
The Kitchen Girl says
Hiya! I think you'll be fine to add the tuna without adding liquid, but be prepared to add a few splashes if it feels like it needs it. As for adding veggies and cheese...that can never hurt 😉 Let me know how it turns out for ya!
Diana says
My daughter, who has Down Syndrome and I made this. Such comfort food, and so easy to prepare! Thank you so much
The Kitchen Girl says
Awww yay Diana! What a great activity for you and your daughter ...so happy to hear it 🙂 Thanks for the feedback!
Amy says
Can you double this recipe? If so, should I double the chicken stock or keep it the same. I have read when doubling some pasta dishes you don’t always double the liquid. I have an 8qt IP. Thank you!
The Kitchen Girl says
Hi Amy, I'm not sure which pasta dishes would not require doubling, but this one definitely does require it. Let me know if you have any other questions. Enjoy!
Howard says
I wanted to let you know that I made the tuna casserole again yesterday. I was looking for a can of peas and noticed a can of mixed vegetables on the shelf. I looked at the can - it had the peas and carrots - plus corn, green beans, and lima beans. I thought to myself that would provide even more flavors and textures for the casserole. OK, truth is I saw a lazy way out of chopping up a carrot. So I used the mixed veggies in place of the peas and carrots. It was still wonderful! Probably going to go the mixed veggie route from now on.
The Kitchen Girl says
Awesome, Howard! Any veggies will work and you can be as lazy as you want 😉 So glad you enjoyed the recipe and thanks for taking the time to review 🙂
Howard says
I made this yesterday, and was skeptical at first because there just didn't seem to be enough liquid in the pot. However, it came out PERFECT! Thank you.
The Kitchen Girl says
Yes, Howard...I think that happens to me with every pasta dish in the IP So glad you enjoyed the recipe. This tuna casserole is def a fav
Cathleen says
I have never thought of making this in an Instant Pot!! Wow, what CAN'T the Instant Pot do?
The Kitchen Girl says
Haha right?! This tuna casserole is literally a toss-and-start too! Enjoy!
JB says
Whoah, you turned my favorite childhood meal into the best tuna casserole ever! Lots of flavor, no canned soup, and no mushy noodles EVERY time I make it, which is often. Thanks TKG!
Sue says
We don't have an instant pot - can you give us directions for doing this without one?
The Kitchen Girl says
Hi Sue, sorry for my delayed response. Yes, I have a skillet tuna casserole that's very similar. Let me know if you have any questions on it Cheers!
Jen says
Tuna has been a staple here during quarantine - and so has the instant pot. Looking forward to making this!
The Kitchen Girl says
Haha yes!! Same here...glad you can enjoy this one 🙂 Thanks, Jen!
