    🍴 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!

    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.

    Can I use canned peas in tuna casserole?

    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.
