Tuna Noodle Casserole With Veggies

Tuna Noodle Casserole With Veggies

Pasta casseroles are a great way to feed a hungry crowd, because who can say no to hot, bubbly pasta fresh from the oven?!

Unlike most of the fat-laden casseroles out there, this casserole recipe features protein and plenty of fresh veggies.

This Tuna Noodle Casserole with Veggies recipe is a healthier twist on an old favorite that you can probably pull together without an extra trip to the grocery store.

Tuna Noodle Casserole with Veggies Recipe

Tuna is the star protein in this recipe. Just crank open a couple of cans, drain the liquid, and sprinkle the tuna into the hot pasta… so easy!

What I love about this recipe is that it’s loaded with lots of colorful veggies, including kale, mushrooms, and peas (you can get creative and swap in your favorites, like carrots, peppers, or spinach).

Instead of using gobs of cream and butter and a thickener (or canned creamed soup) to create a creamy sauce, a little bit of olive oil, reduced-fat milk, and a couple of spoonfuls of whole-wheat flour do the trick perfectly here.

And because there are so many delicious fillings in this tuna casserole, you can actually ease up on the amount of noodles.

Pro tip: For the best tuna noodle casserole, stop cooking your noodles and drain them when they are still al dente (a little bit firm).

They’ll continue to cook in the oven and absorb the flavors of the sauce without becoming mushy.
