During elementary school, my Mom and Dad would sometimes forget to put lunch money into my account. So on the days I couldn’t get a hot lunch, the lunch ladies would offer me a simple tuna sandwich. Back then, I truly despised tuna so I’d skip the sandwich and go hungry until I could get home and stuff my face with one of Dad’s delicious turkey sandwiches. Sad, but true.
I look back on this memory and think about how I wish I had the taste buds of an adult as a child because these days I find myself LOVING tuna. From honey mustard apple tuna salad to thai tuna patties, I can’t get enough of the inexpensive, protein packed amazing flavor that tuna brings to meals.
Funny enough, my bestie and I were recently talking about traditional recipes that we had growing up that could be made a little bit better for you. She suggested that I make a healthy tuna noodle casserole, as that was one of her favorites growing up. So I gathered up my reusable bags, headed to Trader Joe’s, threw around my tiny red cart like a woman on a mission and filled it to the brim with plantain chips (hi, I’m obsessed) and delicious ingredients for this healthy tuna noodle casserole.
What’s in tuna noodle casserole?
If you haven’t had tuna noodle casserole before, then you might be wondering what the heck it is. Traditional tuna noodle casserole is made with cream of mushroom soup, egg noodles, peas and of course tuna. Most people top it with breadcrumbs or even potato chips for a crunchy topping. It’s creamy, savory, and absolutely delicious!
I say, why not make tuna noodle casserole from scratch with better for you ingredients? My recipe is healthier, customizable and doesn’t involve any canned soup. Plus it’s EASY! To make this healthy tuna noodle casserole recipe, here are the ingredients you’ll need:
- Pasta: feel free to use any kind of noodles you’d like. I prefer shells, large elbow noodles, or bowties for this recipe. If you are gluten free, please feel free to use your favorite gluten free noodles.
- Butter: a little goes a long way in helping flavor and break down the onions and mushrooms, but also to make a slurry parmesan gravy sauce to coat all the pasta
- Onion: white onions are best in this recipe, but yellow onions will work too.
- Mushrooms: you’ll need 8 ounces of sliced baby bella mushrooms in this recipe. If you’re not a mushroom fan, feel free to skip and add something like green beans or spinach instead.
- Thyme: the flavor of thyme creates amazing depth of flavor and savoriness in this recipe.
- Flour: you can use all purpose flour, whole wheat flour or an all purpose gluten free flour in the sauce. Coconut flour and almond flour will not work.
- Milk: you have the option of using whatever milk you’d like. I have only tested this recipe with unsweetened almond milk, but I think skim milk or unsweetened cashew milk would work well.
- Garlic Powder: always more garlic, right?
- Parmesan Cheese: it creates the perfect amount of sharp flavor melted into the sauce
- Tuna: you’ll need two cans of tuna for this recipe. Make sure you drain the cans before adding the tuna to the casserole!
- Peas: because it’s not a tuna noodle casserole without peas.
- Breadcrumbs: I still kept the delicious crunchy topping because who doesn’t love a good crunch? If you are gluten free, feel free to use gluten free breadcrumbs, gluten free potato chips that have been crushed up, or gluten free crushed crackers (Simple Mills crackers would be delish!).
Doesn’t it look down right FABULOUS? I was so elated about this tuna noodle casserole that I pretty much kept the entire pan to myself for the entire week, I reheated leftovers for lunch and dinner and gobbled up every last bite.
SO FREAKING GOOD. AND CREAMY. AND SAVORY. AND HOMEMADE! AND HEALTHY too. What more could you want?!

Cook your mushrooms: Place a large pot over medium-high heat and add in 1 tablespoon butter. Once butter melts, add in the mushrooms, onions, thyme and salt and pepper. Stir occasionally until mushrooms and onions are cooked down about 4-6 minutes. Transfer to a bowl.
In the same skillet you cooked mushrooms, add in 2 tablespoons of butter and place over medium heat. Once butter is melted, whisk in a little bit of the flour and then slowly add in milk, a little bit at a time, alternating with the flour and vigorously whisking away any lumps. Bring mixture to a boil, then reduce heat and simmer for a few minutes stirring every so often, until the sauce thickens up. If it gets too thick, add in ¼ cup more milk.
Once thick, turn off the heat and stir in garlic powder, parmesan cheese. salt and LOTS of freshly ground black pepper.
Stir in cooked noodles, mushroom and onion mixture, drained tuna and peas. Season again with salt and pepper, to taste. Pour mixture into your prepared baking pan.
