On the lookout for ways to feed a crowd simply and easily — without losing out on flavor? Of course you are! To hit all of those objectives, nothing really does it like a gratin: throw everything in a pan, sprinkle some cheese over the top, pop it in the oven, and you’re good to go.
But wait, what is a gratin, really?
More commonly known, at least in America, as a casserole, a gratin is a baked dish so named for the gratinéed topping — a word that in French means bubbly and brown, which usually indicates that there’s some sort of cheesy goodness sprinkled over the top.
These dishes are so simple to make and great for feeding a crowd when you’re short on time, mainly because a lot of prep can be done in advance. Gratins can often be assembled ahead of time and then sprinkled with topping and popped in the oven to warm just before serving. But that’s not the only reason to fall head over heels for gratins — they’re also one-dish meals that are usually chock full of flavor and nutrients. Here are just a few of our favorites for the colder season, either for a quick and easy one-dish meal to feed a crowd or as a great side for a holiday buffet.

6. Vegan Sweet Potato Gratin
This delightfully different sweet potato gratin stands out amongst other casseroles due to its unique flavor profile.

Your favorite almond butter also goes into the base, ticking the protein box in this recipe and making it an ideal main.
Gratin Recipes Perfect as a Side Dish

7. Red Skin Potato and Thyme Casserole

8. Classic French Gratin Dauphinois
There are two camps when it comes to gratin dauphinois — those who add cheese and those who, quite resolutely, do not. This one has a layer of bubbly cheese sprinkled over the top, but you can just as easily use only cream and still end up with a decadent result. This recipe allows you to choose whichever option you prefer.
9. Zucchini Casserole
When zucchini is cooked just right, it takes on a lovely, sweet aroma that pairs wonderfully with melted cheese. That’s the key to this zucchini casserole recipe, which is topped with a combination of different melting cheeses as well as a touch of panko for crunch.

Be sure your salad has a bright vinaigrette made with mustard to complement and bring out the flavors of this gratin.
A Delicious Dessert Gratin Recipe
Yes, even desserts can be gratinéed, as long as you have some fresh fruit on hand. Pick your favorite winter fruits to make gratin sweet as (and much easier than) pie.
