🔀 Substitutions & Variations
- Chicken Stock: Choosing between chicken stock or vegetable broth for your one pot tuna casserole is largely a matter of personal preference. While both will work well in this dish, the vegetable broth may make the recipe slightly healthier if you are concerned about reducing sodium intake. Additionally, chicken stock tends to create a richer flavor that works well with the savory tuna and umami flavors of the mushrooms.
- Heavy Cream: If you prefer to use heavy cream instead of half and half, this will work well in your Instant Pot tuna noodle casserole recipe. However, keep in mind that this may change the texture and flavor slightly. Heavy cream is thicker and richer than half and half, so if you want a creamier dish you may want to try this substitution when pressure cooking.
- Noodles: If you have an egg allergy, you can switch out the egg noodles for an egg-free spiral-based pasta.

💭 FAQs
Tuna casserole is a classic American dish made with egg noodles, tuna, and cheese. It is a simple dish to make and is typically served as a quick and easy dinner perfect on a weeknight.
Tuna Noodle Casserole’s appeal lies in its comforting combination of tender egg noodles, creamy sauce, flaky tuna, and often additional savory elements like onions and seasonings, that create a harmonious blend of flavors and textures that evoke a sense of homey satisfaction.
The answer is no. Egg noodles and spiral pasta are very similar, however, spiral pasta tends not to be made from eggs. Noodles, on the other hand, have much more egg in them, and the spiral-shaped dry pasta makes them great for casseroles and stews. If you have an egg allergy, you can switch out the egg noodles for an egg-free spiral-based pasta.
Mushroom soup is the perfect addition to tuna casserole because it adds a rich, creamy flavor that complements the savory tuna and tender pasta. Whether you prefer traditional cream soup or opt for low-sodium you can find a variety of options to make this Instant Pot tuna casserole recipe your own.

If you love this pressure cooker Tuna casserole recipe then you may also love the following posts:
This is a very forgiving recipe, as I made a few changes (omit dill weed, sub evaporated milk for half and half, sub 2x diced sweet onion for white onion, sub 2x frozen pea & carrot mix for frozen peas) and missed the instruction not to stir before pressure cooking, but it still came out well. This will be my go-to recipe for tuna casserole, as I grew up making upgraded Tuna Helper, not the baked casseroles with crispy topping. This was much better and faster, using only what I had on hand.
Making any adjustments where you feel you can make changes is the best thing about cooking. I am glad you liked this recipe. As for the Stirring instruction, we can add that to the recipe. Thank you for the input.
I am confused. At the end of step 5 it says do not stir. But the first thing step 6 says is stir well. Which is correct?
Hi burt,
You can stir the ingredients at any point. We just prefer to layer the ingredients and stir it all at the end but either way will work.
