The Best Old Fashioned Tuna Noodle Casserole

OLD FASHIONED TUNA NOODLE CASSEROLE (RAVE REVIEWS)
Egg noddles in a delicious creamy mushroom soup sauce tossed with tuna, sauteed onions, peas and cheddar cheese, topped with crushed potato chips then baked to perfection…just like grandma used make. Old school comfort food at its best.

If you were a kid growing up in the 70s and 80s, there’s a good chance this casserole was served often at the dinner table – it was a staple in our home. This recipe was passed down from my grandma and has changed a smidgen over the years but still remains a classic.
Preheat oven to 350 degrees F. Spray a 9×13 baking dish with non-stick cooking spray. Prepare egg noodles, making sure to slightly under cook them by 2 minutes so they are slightly firm. Drain well.
