Homemade Tuna Noodle Casserole

Tuna Noodle Casserole isn’t a new dish, it’s a beloved vintage casserole we’ve eaten for generations. The most common version utilizes canned soups for the sauce making it a super easy dish to prepare. While I use canned soups from time to time in casserole recipes such as crockpot chicken and dressing and au gratin ranch potatoes, this tuna casserole is made with a homemade sauce to kick it up a few notches.

Tips for Making Homemade Tuna Noodle Casserole

  • I use wide, not extra wide noodles, in this dish.
  • You can use white cheddar, regular cheddar, Gruyere or Swiss cheese in this dish. In a pinch, monterey jack makes a delicious mild cheese sauce. Adapt the cheese using your preference or, what you have on hand.
  • I recommend topping this with crushed french fried onions however, you can also use buttered bread crumbs or even crushed potato chips.
  • Depending on your family’s taste one cup of peas may be ample. If they love peas, you may use up to two cups.
  • Adding seafood seasoning gives this dish a little something extra in flavor. I use Old Bay and Seafood Magic but, there are a plethora of seafood seasoning combinations available.

Dishes to Serve with Tuna Casserole

This casserole can stand alone, if you’re in a hurry. That being said, a wedge salad and some warm garlic bread goes a long way alongside this filling pasta dish. You may also enjoy this tuna salad recipe from Spend with Pennies.

    1. I haven’t tested that swap specifically, but you likely could adapt using whole wheat flour as a thickener in place of the all purpose flour. If you try it, let us know how it goes.

  1. Can this be made and frozen unbaked and then before baking, top with the french fried onions? I would love to make this for my Mom but put in 2 pans so one could be eaten and the other one froze. Some casserole freeze well and some do not. Thank you.

    1. Hi Candice, you sure can. When freezing pasta, try not to overcook it initially, and it should be fine. Yes, top with french onions just before baking.

  2. Hi Melissa, my family are not tuna fish eaters. Could I use can chicken instead? What seasoning would you suggest I use, instead of the old bay?
    I love your recipes!


    1. Hi Sandy, you can indeed use chicken in this recipe in place of tuna. Rotisserie chicken seasoning or maybe Herbes de Provence, the sky’s the limit with seasoning blends.
