If You Have Leeks, Heavy Cream, White Wine, And Butter, You Have The Start Of A Melt-In-Your-Mouth French Side Dish

Prized for their delicate, sweet, and buttery flavor that mellows when cooked, leeks are one of the cornerstones of traditional French cuisine. I had no idea just how prominent the vegetable was in many French dishes until it was swiftly ingrained in my head during my culinary school tenure. The adaptable stalk is used in many dishes you may already know, including the classic vichyssoise, aka one of Julia Child's favorite soups. Now, the humble vegetable is enjoying its rightful moment in the spotlight, going viral on social media, with home cooks preparing poireaux braisés (braised leeks) in a buttery white wine reduction with cream.

Leeks are one of the largest members of the allium family, which includes onions, garlic, and shallots, and they're also low in calories and rich in fiber, vitamins, minerals, and antioxidants. Large in size, the tender white and light-green portions are most commonly used in cooking, while the darker leaves are excellent for stocks and broths. Braising is a classic method in which a food — whether protein or vegetable — is first seared and caramelized in a pan before adding liquid to finish the cooking. The leeks are already tender as-is, so braising them intensifies their delicate sweet onion flavor.  Whether served as a sophisticated side dish alongside roasted chicken or as the centerpiece of a vegetable-forward meal, these creamy, tender leeks prove that an often-overlooked allium deserves a place at the table.

The elegant dish can easily be replicated at home, no fancy culinary training required. Cut one-inch pieces from the white part of the leek — that's what you'll be cooking — and sear them cut-side down in melted butter (or extra virgin olive oil) in a hot skillet, until deeply golden brown. Remove and reserve them in a baking dish, and deglaze the pan with white wine, scraping up any browned bits from the bottom. Allow the wine to reduce by half before lowering the heat and whisking in heavy cream and Dijon mustard.

Once your sauce thickens enough to coat the back of a spoon, pour the braising liquid over the leeks and bake them in a 325-degree Fahrenheit oven until bubbling and golden brown. For a cheesy crust, sprinkle the leeks with a combination of freshly grated Parmesan and Gruyère before baking. You can also introduce fresh herbs, such as thyme or tarragon, to the braising liquid for a fresh herbal aroma before your leeks hit the oven.

A word to the wise for leek beginners: Properly trimming and cleaning your leeks is essential, as their tightly packed layers tend to trap dirt and grit from the soil in which they grow. Choose thicker leeks for this dish, as their substantial size allows them to develop a beautiful golden crust while retaining their structure during cooking. Thinner leeks can cook too quickly, becoming overly soft or even burning before the braising liquid has had a chance to work its magic. When I make braised leeks, I do everything in an oven-safe pan as opposed to transferring to another baking vessel; the flavors continue to build, and it's one less pan to clean after all your (not-so) hard work.
