🥘 Ingredients
Olive oil- You will need some olive oil to saute the ingredients in.
Butter- This will give us a nice rich flavor.
Onion- For added depth of flavor and some natural sweetness, use an onion. I usually prefer white or yellow onions.
Chicken broth- You'll need some chicken broth to hydrate the recipe and give it a nice flavor. Water and chicken bullion could be used in a pinch. This also helps to give the Instant Pot the necessary liquid needed to operate properly.
Salt- For a natural flavor enhancement.
Seasonings- You will want to use some black pepper, garlic powder, and onion powder. This will give us a great flavor with basic seasonings.
Half and Half or milk- This will hydrate the recipe and create a creamy consistency.
Egg Noodles- We love to use egg noodles in our tuna casseroles. They cook quickly, and they're cheap and filling.
Tuna- Use your favorite brand of canned tuna (in water).
Cream of mushroom- Adding in cream of mushroom soup gives us a great base and adds a lot of flavors too.
Frozen peas- You'll need some frozen peas as they will hold up much better than canned peas. You could add canned peas (drained) at the very end if you don't have frozen peas on hand.
Cheese- For a great depth of flavor, we use a combination of cheddar cheese and parmesan cheese.
Ritz Crackers- For the topping, adding some crushed Ritz crackers will give us a buttery crunch and a little salty goodness. It's a great addition to many of our casseroles!

🔪 Instructions
Check out how to make Instant Pot tuna casserole with these simple step-by-step instructions:
Set the Instant Pot to Saute (10 minutes) and add in the olive oil, butter, and diced onions. Cook until the onions are somewhat clear.
Add in the broth and seasonings. Stir to combine.
Stir in the half and half.
Add the egg noodles and DO NOT STIR. Smoosh them down a bit to try and get them wet, but you won't get all of the noodles submerged.
Layer the drained tuna meat over the top, then spread the cream of mushroom soup over the top of that.
Close the lid and seal it. Set it to High Pressure for 1 minute with a 10-minute Natural Pressure Release.
Release the remaining pressure and open the lid. Stir in the peas and cheese. Put the lid back on and wait 1 or 2 minutes for the cheese to melt and the peas to warm up.
Serve or place in a casserole dish. Top with Ritz crumbs and broil on high for 1 minute in the oven.
Serve warm.
🍴 Recipe Tips
The most important thing to remember about making this creamy tuna casserole in the Instant Pot is to NOT stir unless directed. Layering the ingredients like this is what gives the best results.
Dairy items can often have bad results in the Instant Pot, but this method of layering is what keeps things from turning sour.
The good news is that it's really easy and that not stirring just means even less work for you!
I recommend taking the additional step of broiling it in the oven with the Rit topping though. It's sooooo good that way!
💭 FAQs
You can place this tuna casserole (after it's cooled) in a freezer-friendly container for up to 3 months. Just thaw overnight in the fridge before reheating in the oven.
Absolutely! Just make sure to drain them first. Sti them in at the same point as you would the frozen peas and you'll be fine.
Leftover tuna noodles can be stored in an airtight container in the fridge for 3-5 days. For best results eat it sooner rather than later or freeze leftovers if you know you won't be getting to them soon.
