Tuna Noodle Casserole

Tuna Noodle Casserole was very popular when I was a newlywed- 51 years ago. Over the years, I stopped making it. That being said, there is nothing like a creamy Tuna Noodle Casserole to warm your tummy and comfort you on a snowy Winter’s night. Years ago, I used canned condensed Cream of Mushroom Soup to make the sauce. These days, I make a sauce with a box of creamy Portobello Mushroom Soup and add more mushrooms to it. Topped with Panko and packaged fried onions, this casserole lives up to its legendary place in the annals of comfort food.

For another creamy comfort food, try Chicken Pot Pie !

Note: This recipe is non-dairy. Add two cups of shredded cheddar cheese to the sauce if you want an even richer sauce and a dairy meal.
