Potato and Leek Gratin #SundaySupper

Potato and Leek Gratin

Spring, Daylight Savings Time, Easter–they bring rejuvenation, new beginnings, and an opportunity to bask in the warmth of longer days. We’re not very religious around here, but our family does observe all the major Christian holidays. With Easter being the most important, at least to the devout, we use this holiday to bring family and friends together in celebration. This week for #SundaySupper we’re helping you fine tune your Easter and Passover menus with dozens of recipes suitable for either holiday table (see below). Me? I’m preparing a Potato and Leek Gratin. Potatoes, leeks, cheese–how can you go wrong?

When considering traditional Easter (and Passover) fare, lamb is customary and carries special meaning for both holidays, while ham is rooted in U.S. customs. A decadent side of potatoes au gratin pairs well with both, whether you’re dining on a classic roast leg of lamb or a salty-sweet glazed ham. The thinly sliced potatoes and leeks are simmered in milk and herbs, then layered with Gruyere cheese in a gratin dish, and baked until golden and bubbly. Creamy, cheesy, potato deliciousness.

What is au gratin anyway? The term originates in France and dates back to the 16th century, referring to that part of a cooked dish which stuck to the pot or pan and had to be scraped (gratté) off so as not to be wasted. Nowadays, au gratin has come to describe a technique of creating a crisply baked top, usually with cheese. However, you can achieve the same effect without cheese, such as with gratin dauphinois, which is correctly made with sliced potatoes baked in cream and no added topping. This dish, adapted from Vegetarian Cooking for Everyone, is dauphinois kicked up a notch.

The recipe can be prepped and assembled in advance, then pop it in the oven during the last hour of cooking your meal.

Potato and Leek Gratin

Wash and peel the potatoes, slicing about 1/4 inch thick.  Then wash, trim and thinly slice the leeks, as well as the garlic.

Add the potatoes, leeks and garlic to a large pot, along with the milk, bay leaf, thyme, and salt. Bring to a boil, then reduce the heat and simmer until the potatoes are mostly done but still firm. Remove the bay leaf, then drain, reserving the milk.

While the potatoes are simmering, grate the cheese. It’s easy work if you have one of those Zyliss numbers. By the way, feel free to sub in Emmental or Swiss instead of the Gruyere.

Before piling stuff in, you’ll need to rub the dish down with garlic then grease it with butter. This should have been a gratin dish, but since I don’t have one, I’m using my trusty Corningware Oval 2 Quart Casserole. Start with a layer of the potato/leek/garlic mixture on the bottom, sprinkle that with a little pepper and nutmeg, then top with a handful of cheese. Repeat this until all the potatoes and cheese are used up, saving some cheese for the top. Pour the reserved milk over this until it comes up to the top layer of potatoes.

  3. On the bottom of the gratin dish, arrange a layer of the potato/leek/garlic mixture, sprinkle with a little pepper and nutmeg, then cover with a handful of the cheese. Repeat layers until all the potatoes and cheese have been used (ending with the cheese on top).

hehe I enjoyed the little historical explanation of the name gratin. I thought it to be much older though. Anyway, leek and potato gratin sounds like food marriage to me! Great combination and a dish that I personally make a lot too.

Time for me to pull out my trust 2-quart oval Corningware French White dish too! What a great gratin for Easter and would be perfect to go with ham.

Thanks! Potatoes and cheese always make a great combination! I especially love serving this with ham.

Excellent, flavorful recipe with just the right balance of potatoes, leeks and herbs. I only had 1% milk on hand, which made it a little runny but it will firm up in the fridge. Delicious!
