Yukon Gold, Leek and Fennel Gratin is the “Up Town” cousin of plain au gratin taters!

The mellowness of sauteed leeks and fennel combine to make Yukon Gold, Leek and Fennel Gratin a dish fit for company!

If you are planning for company, especially at Easter, this is a fabulous recipe to serve.

It’s really a good idea to choose a few Easter dinner recipes that can be made ahead of time.  That’s how a busy host can keep things running smoothly and enjoy their own parties.  This just happens to be one of those dishes!

I usually prepare the Yukon Gold-Leek-Fennel Gratin the morning before I’m serving it.  The gratin keeps just fine if made the day before, kept tightly covered in your refrigerator.  Easy peasy!

The combination of the creamy potatoes, leeks and fennel meld into a casserole that is beyond what any potato can be by itself.

For those of you thinking that the fennel will overwhelm the dish, you’ll be pleasantly surprised.

And those of you who are thinking they don’t really like fennel, have you tasted it after a long roasting in a creamy, cheesy sauce?  I didn’t think so.

This is a recipe that should go on your Easter dinner menu.  Write it down in your planner, print out the recipe and then you can check “side dish” off your “find recipe for” list today!
