Healthy Tuna Noodle Casserole

This Skinny Tuna Noodle Casserole doesn’t taste “healthy”. It has extra veggies, a high-quality tuna, and a creamy sauce for a fantastic, easy meal.

If you’re as old as I am, chances are you had a lot of tuna noodle casseroles as a kid. Cooked noodles, a can of tuna, some canned soup and maybe some onion or mushrooms. That was considered a well-rounded meal back then and it sure tasted good to me and my sisters.

I still love a good tuna noodle casserole but I wanted to create a recipe worthy of my tastes today. If I could do that and keep the calories down, too? Even better.

This Skinny Tuna Noodle Casserole doesn't taste "skinny" at all! Extra veggies balance with whole milk and delicious Genova tuna for a casserole everyone will rave over!

How do you make a healthy tuna noodle casserole?

You’ll want to begin with a high-quality tuna; one that tastes fresh and flavorful. If the star of my casserole is tuna, it had better be top-notch (I prefer Genova tuna). Using a cheaper tuna is fine, but be sure it has large chunks of flaky tuna and isn’t just a mush inside the can. This is a tuna noodle casserole with egg noodles and you want the pasta and tuna to be tender bites without being a mushy mess.

Saute your veggies, add your sauce ingredients and simmer. Mix in more veggies and tuna, then layer it with the noodles in a baking dish. Add your crunchy topping and bake until the topping is golden brown and the casserole is bubbly hot.

Is it a coincidence that I’m getting super hungry right now? :)

Can you freeze tuna casserole?

You can! Just make sure you seal it tightly before freezing to keep as much air out as possible. When you’re ready to enjoy it, thaw it in the refrigerator overnight and bake as usual.

What side dishes to with tuna casserole?

In my opinion, you don’t really need a side dish with this particular tuna noodle casserole since it already has loads of pasta, vegetables, and tuna. If you still want to serve something alongside it, I’d suggest either a salad or a fresh vegetable side such as fresh sliced tomatoes ( you could add a dollop of ricotta cheese and fresh basil, too).

Of course, adding a dessert instead of a side would be another option. Fresh fruit at the end of your meal would round this out nicely and keep it healthy, too.

  • 3 tablespoons all-purpose flour
  • 1 14.5-oz can chicken stock or broth
  • 1 tablespoon prepared horseradish
