Tuna noodle casserole, made in the Instant Pot! A perfect way to make dinner turn out perfectly every time! So creamy cheesy and downright delicious don't be surprised if you lick the plate clean.
Set your Instant Pot to Saute and set the timer for 10 minutes.
Heat the olive oil, butter, and onions. Cook for about 5 minutes until onions are translucent.
Add in the broth and the seasonings. Stir to combine.
Add in the half and half, mix again.
Add the egg noodles, and do not stir. Smoosh them down slightly with the back of a spoon to try and get as much submerged as possible. You will not be able to cover all of the noodles, and that is okay.
Lay your drained tuna over the top of the egg noodles. Do not stir.
On top of the tuna, spread out the cans of cream of mushroom. Do not stir.
Close the lid and seal it shut. Set it to High Pressure for 1 minute. Do a 10 minute Natural Pressure Release before releasing the remaining pressure.
After releasing the pressure, stir in the frozen peas and cheese. Close the lid again and let it rest for 2 minutes to melt the cheese and warm the peas.
Stir again and serve or place into a casserole dish and cover with Ritz cracker crumbs. Broil for 1 minute on high.
Serve warm.
Notes
Recipe TipsThe 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 layering method 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. StorageYou 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. 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.
