Notes

Carefully add the ingredients. Layering the ingredients helps in avoid getting a burn message on the Instant Pot due to the pasta soaking up the liquid too quickly
Solid white albacore tuna is preferred for this recipe since it has a milder tuna flavor. Or choose tuna in water over in oil.
Use regular milk or other milk of choice (if dairy free). If you don’t mind the extra calories, use half and half for an extra creaminess.
Use elbow macaroni in place of egg noodles. Increase cooking time to 4 minutes
Use gluten free pasta if desired and cook for 3 minutes.
Leave out the cheese or substitute dairy free cheese if desired
If you would like a crunchy topping, transfer the cooked tuna casserole to a casserole dish and add ½ cup of panko or regular breadcrumbs and broil about 6-8 inches from heat for a 2-4 minutes until brown. (Careful not to burn)
Add other vegetables like diced baby carrots and/or sliced mushroom if desired. You can also use frozen mixed vegetables to save even more time.
Store in an airtight container for up to 3 days
Freeze for up to 2 months
