Healthy Tuna Casserole

This classic tuna casserole isn’t exactly like your mom used to make… It’s better!
I don’t know about you but when I think “healthy dinner” tuna casserole wasn’t what came to mind. Why not? This meal is an excellent source of protein, potassium and vitamin A! Made from scratch, and stuffed full of obvious and not so obvious vegetables this healthier version of the tried and true classic combines my favorite things, easy and healthy!

You are going to need: Veggie pasta, canned tuna, whole milk, butter, flour, frozen peas, cheese, breadcrumbs, garlic powder, parsley, salt & pepper. The the full recipe below for specifics.

Cook the pasta according to the package instructions to al dente. Drain and set aside.

Melt the butter until starting to bubble.

Add in the flour and cook 2-3 minutes until golden and bubbling.

Add in the seasoning and slowly start adding in the milk.

Bring the mixture to a boil and as it starts to thicken add in your cheese.

Once the cheese is fully melted add the sauce to the pasta.

Add in the frozen peas and flaked tuna and mix well.

Bake at 350 F for 15 minutes.

After 15 minutes top with breadcrumbs and additional cheese.

Bake another 5-10 minutes until golden brown.

I recommend serving with a fresh salad and dinner rolls!
