Instant Pot instructions for making this healthy tuna casserole are below.
Making dinner in the Crockpot or the Instant Pot is my favorite. I love putting everything together and walking away! I use the time to workout, clean up the house, or spend some extra time with the kids.
We all have ten things going on at any given time right? Hovering over a delicious dinner is not always in the cards for me. This slow cooker tuna casserole is great for the whole family. Everyone loves it and I bet even the picky eaters can be persuaded with some melted cheese and their favorite veggies.
Ingredients:
- whole grain noodles
- cream of mushroom soup
- vegetables of choice
- tuna
- cheese (optional)
How to Make A Healthy Tuna Casserole in the Crockpot:
Add all ingredients except cheese to a slow cooker and stir together. Use this Fix approved, healthier cream of mushroom soup recipe instead of the canned stuff! If you want to mix it up a little, try using this healthy Cream of Asparagus soup instead!
Place the lid on your crockpot and cook on high for 1 1/2 hours.
Add your noodles during the last 30 minutes of cook time.
Serve and top with cheese, if you’d like.
How to Make Healthy Tuna Casserole in the Instant Pot:
- Add pasta to the Instant Pot. Then add all other ingredients, including 3 cups of water.
- I stir my recipe to avoid the burn warning, but I know a lot of people put their water on the bottom to avoid it–do what works for you!
- Close lid and set your pot on high pressure for 4 minutes.
- Quick release and stir! It’ll be super hot–let it cool before eating.
Can this Tuna Casserole be Frozen?
It sure can be frozen! Make individual servings or a big batch to freeze. I reheat the frozen casserole in the microwave when I’m ready to eat it. This makes it an even better dinner idea for busy weeknights, and a great meal to bring to a new mother or grieving family.

Notes
Nutrition
can you replace the tuna with canned chicken? Everything else the same?
Hi Karli, I’m sure you could! They’re very similar! I wouldn’t change anything if I did that :)
THanks..sorry, I missed that when I first looked at the recipe
Are you meaning the five oz flat cans of tuna?
Yes!
This recipe has all of my favorite ingredients for tuna casserole. Unfortunately, I can’t get away from the “burn” alert. Ugh.
Oh no!! Are you spraying the pot with oil before starting, and are you stirring the contents before cooking?
I see it says eight servings, but what is the serving size for each portion?
It’ll be around 1.5 cups – always best to divide it up though!
For the slow cooker recipe, do you cook the noodles before putting them into the slow cooker or do they cook while in the slow cooker?
Add them the last 30 minutes of cook time!
Would frozen vegetables affect the cooking time in an instant pot?
In this recipe, not for the carrots and peas. If you were adding in frozen cauliflower florets, for example, I might add another minute onto the cook time.
Does this help?
