Cheesy Spinach Gratin

Spinach Gratin Main 1
While some people don’t take an immediate liking to it (or to greens in general), we’ve always had a fierce affinity for spinach. Whether it’s in a fresh salad, sautéed with garlic and lemon, or cooked into a creamy side dish, we’ll take those baby greens any way we can get them, and this dish is our current new favorite in our dinner rotation.

You’ve probably heard of or tried potato gratin, but have you ever had spinach gratin? Essentially creamed spinach that we top with a healthy sprinkling of cheese, this dish will have you hooked after one bite. The cheese melts perfectly on top of the already creamy spinach and the result is a veggie dish that will steal the show every time. Even if you don’t like spinach usually, you should check this out…we promise you’ll love it!
