Tuna Noodle Casserole

Last month when I was interviewed for the New York Times my conversation with the interviewer at one point got on the subject of foods from my childhood that I hold a fondness for. Without hesitation I started talking about casseroles. When I was a kid we ate lots of cream-of-something soup casseroles. As much as we like to get “foodie” around here, those retro condensed soup casseroles are some of my most favorite comfort foods and I still make many of them for my family. One of my favorites back then was tuna noodle. I’m sure my Mom made it the same way lots of people do, with cream of mushroom soup and cheddar cheese, and potato chips on top. That layer of crunchy potato chips melted into gooey cheese was my faaaaavorite thing. We’d always conveniently scoop our servings horizontally, as to scrape off as much of the topping as possible. Kate and I have gotten a lot of requests for a tuna noodle casserole over the past few years, and since one of my New Year’s resolutions was to cook more fish at home (seriously; lose weight, start doing laundry on a regular basis, and eat more fish. The only one I’m totally sucking at is laundry. I should stop making that goal.) I thought this would be a fun recipe to makeover.

Ingredients Needed

This is just a preview of ingredients and method, keep scrolling for full printable recipe.

Medium shell pasta – Tuna noodle is typically made with wide egg noodles, but I like to use medium sized shell pasta because I like how it sort of holds everything together and the little shells fill up with sauce and veggies and bits of tuna. I make it with bowties sometimes too and those work great as well.
Butter – Real butter is always best!
Celery, onion, and mushrooms – Tuna noodle also often includes frozen or canned peas. Have I ever told you I’m not a huge fan of peas? Also commercials where they make babies talk like adults, but we’ll save that conversation for another day. To freshen things up I’m using fresh diced onions, celery, and mushrooms. It may seem like a lot of mushrooms, but remember they cook down a lot.
Olive oil
All-purpose flour
Chicken broth
Milk
Kosher salt
Black pepper
Dried dill
Fresh lemon juice – I kept the lemon juice in the written recipe minimal, simply enough to brighten the flavor, but you can absolutely add more to taste. When I make it, I add quite a bit more. Like sometimes the whole lemon. But you should know by now that me and lemons have a thing.
Parmesan cheese – Freshly grated. I’m using Parmesan cheese, but you could be creative and try out other cheeses. You could go with the retro-classic cheddar or a mild Swiss would be yummy too.
Canned tuna – You can really add as much tuna as you like. I just add one 5 ounce can, but you could add two, or one of the larger sized cans if you want to load it with fish. If you don’t want to make it with tuna, you could sub canned or fresh chicken or turkey.
Choice of topping- In my experience everyone has strong feelings about casserole toppings. So you can switch it up however you like; I sort of use whatever I happen to have at the moment. If I’ve got a bag of potato chips, I go old-school with those. I’ve found that kettle style chips stay a lot crunchier. I also love a cracker crumb topping (as shown in pics); buttery Ritz are super yummy. You could also do breadcrumbs or toasted panko.

How to Make Tuna Noodle Casserole

We’ll start by sautéing some veggies in a little olive oil. Start with your diced celery, since it takes the longest to cook. Then add the onions a few minutes later, and finally your mushrooms. You’ll cook that all down until the mushrooms are cooked to your liking.
When the veggies are done cooking, you’ll take them out of the pan and then start a little roux to thicken your sauce. I use a combo of chicken broth for flavor and milk for added creaminess in this sauce. If you warm both the broth and the milk before adding it to your roux it will mix up a lot easier. Salt and pepper goes in the pot, as well as a hint of dried dill. You’ll add a little fresh parsley and lemon juice and that’s it for the sauce.
Toss the pasta in, along with the cooked veggies and the tuna and cheese. Stir it all together and put it in a casserole dish. I make mine in a pan that’s about 8×8 so the topping is done accordingly.
Pick your topping, and then sprinkle it over a layer of cheese on top. When it bakes up in the oven, the toasty cracker crumbs/chips/breadcrumbs brown up and combine with the melty cheese to form a cheesy crunchy crust on top. Hands down one of my favorite things in the world.
Make sure to let it sit for 10-15 minutes before serving so the sauce can thicken up as it cools a bit. Serve it as a one-dish dinner, or along with a salad and some crusty french bread on the side.
