Collard Greens Au Gratin

Collard Greens Au Gratin

Dishes that are “au gratin,” like this casserole of collard greens au gratin, sound a lot fancier and more complicated than they actually are.

Au gratin is the French term used to describe a dish that’s layered with cheese (and sometimes butter, cream, or bechamel sauce), sprinkled with breadcrumbs, and baked in the oven — there’s no better way of getting in your daily greens than with a side of cheese and breadcrumbs, right?!

You can make just about anything au gratin. Potatoes are the most famous, but pasta, fish, and all variety of vegetables can get the cheese and breadcrumbs treatment.

In terms of healthy sides, traditional au gratin dishes don’t normally make the cut.

But luckily for you, this recipe uses simple techniques and inexpensive, healthy ingredients so you can make any night a special occasion.

Collard Greens Au Gratin Recipe

The first step to this delicious dish is to blanch the collard greens — very quickly boil the greens to soften the leaves.

Then, you’ll strain the greens and dunk them into a bowl of ice-cold water to arrest the cooking process.

Blanching helps vegetables cook very quickly while retaining their vibrant color.

Pro tip: You can make this recipe in advance — prep everything except the breadcrumb topping and store in the fridge overnight. When you’re ready for dinner, simply sprinkle with breadcrumbs and pop it into the oven.
