Potato-fennel gratin

Will there ever be a combination as perfect as potatoes and cheese? I’d say this combination of potatoes, cheese, and fennel is definitely a runner-up! If you’re searching for a luxurious side dish to wow all your guests at a dinner party, look no further than this Potato-Fennel Gratin. It’s sure to delight guests of all ages, regardless of whether they’re picky children or refined adults. (If they’re refined children or picky adults — well, I’m sure they’ll enjoy it too.)

Each bite of this Potato-Fennel Gratin feels like heaven. The heavy cream provides a smooth backdrop to the rich, salty, and mildly earthy Gruyère cheese; the thin potato slices are soft and filling, and the sautéed fennel and onions add a surprisingly sweet spot.

Even with how elegant it looks, it’s still easy to make — you’re essentially just mixing ingredients together and laying them in a baking dish. It does take a total of one hour and 40 minutes to prepare, but I guarantee your kitchen will smell glorious while it’s baking in the oven — all the better to rev up your appetite! It’s great as a side dish for chicken or pork, but you might just find yourself sneaking in more bites of this than the main course!

To get the best results for your potato slices, try using a mandoline slicer for consistent thinness. Just be careful when using one, because those blades are wicked sharp! If you cut yourself while slicing, it’s likely to be deep. To protect yourself, consider getting some cut-resistant gloves or a mandoline with a “safe” design.
