Tuna Noodle Casserole

Tuna Noodle Casserole

As I’ve gotten older my palate has become more adventurous, preferring flavors that surprise and excite me. But I grew up in the Midwest in the ’80s when creamy casseroles were a dinnertime staple, so I still have a soft spot for classic dishes like this Tuna Noodle Casserole. It might not be as flashy as many of my other creations, but this Tuna Noodle Casserole recipe is filling, creamy, and totally comforting! I did update the classic a bit to fit my current cooking style by making this tuna noodle casserole 100% from scratch, with no canned condensed soup.

What is Tuna Noodle Casserole?

This classic casserole dish starts with a creamy mushroom sauce combined with delicate egg noodles, peas, and tuna, then it’s topped with a buttery breadcrumb, cracker, or potato chip topping. The classic version of tuna noodle casserole uses canned condensed cream of mushroom soup for the sauce, but in the recipe below I’ve whipped up a homemade creamy mushroom sauce instead. It does take a little more time, but it’s totally worth it, IMHO!

Ingredients for Tuna Noodle Casserole

Here’s what you’ll need to make this cheesy, creamy, cozy, and comforting tuna noodle casserole recipe:

  • Vegetables: This cozy casserole features onion, mushrooms, and peas for tons of color, texture, and flavor.
  • Butter: Butter is the base for the thick cream sauce and makes the breadcrumb topping deliciously golden brown and crispy.
  • Flour: Flour combines with the butter to create a roux that thickens the creamy sauce.
  • Milk and Broth: We use a combination of both milk and broth to create the creamy sauce so that it’s both rich and flavorful.
  • Cream Cheese: Cream cheese thickens the creamy sauce and gives it tons of flavor, similar to the canned condensed soups that your grandma used.
  • Wide Egg Noodles: The delicate texture of egg noodles and their wide shape balance perfectly with the chunks of tuna throughout.
  • Tuna: I went with chunk light tuna packed in water for this recipe to keep it light and budget-friendly. If you have room in your budget, solid white albacore tuna will give you even better flakey chunks of tuna in the casserole.
  • Breadcrumbs: A simple buttery breadcrumb topping creates just the right amount of texture on top of the casserole as it bakes. Some people like to use crushed Ritz crackers or even potato chips in place of the breadcrumbs.
  • Parmesan: A little Parmesan mixed in with the breadcrumb topping gives the breadcrumbs just the right amount of flavor.

Cheesy Tuna Noodle Casserole

One of the most popular variations of this classic casserole is to add cheddar cheese. So if you like your tuna noodle casserole extra cheesy, feel free to stir in a cup of shredded cheddar when combining the sauce, pasta, and tuna. It will get nice and melty as the casserole bakes! Parmesan is another great option.

What to Serve with Tuna Noodle Casserole

This casserole can be a bit on the heavy side, especially if you prefer to make the cheesy version, so I like to pair it with a light and simple side salad. The delicate flavor and texture of the salad perfectly balance the creamy tuna casserole and it helps you get a little more green on that plate. Plus, it only takes five minutes to make! A simple Three Bean Salad might also be nice.

How to Store Leftovers

Tuna noodle casserole can be stored in the refrigerator for about four days, although it will get drier the longer it is in the refrigerator. You can also freeze tuna noodle casserole for longer storage. Once it’s fully chilled in the refrigerator, simply transfer to the freezer where it will keep for about three months. I suggest dividing the casserole into single servings before freezing so you can reheat one portion at a time. To reheat, let the frozen tuna noodle casserole thaw in the refrigerator over night, then microwave until hot.
