Pancetta-Wrapped Leek Gratin

Chef John

"I'm all about simply prepared vegetables, but every once in a while I need to cover them in caramelized pork and cheese, and this stunningly delicious pancetta-wrapped leek gratin was one of those times. I love those times."

  • Ready In

  1. Preheat oven to 400 degrees F (200 degrees C).
  2. Wrap each leek half in pancetta.
  3. Drizzle olive into a baking dish and use a pastry brush to spread oil over the bottom of the dish and partway up the sides. Season dish with salt, black pepper, and cayenne pepper. Place leeks close together cut-side down into the prepared baking dish. Pour chicken broth and wine over leeks. Cover baking dish tightly with aluminum foil and set it on a baking sheet.
  4. Bake in the preheated oven until just tender, about 45 minutes. Uncover the baking dish, pour cream over the top, and spread Parmigiano-Reggiano over the top. Return to oven and bake until cheese is golden and sauce is bubbling, 15 to 20 minutes more. Cool for 10 minutes before transferring leeks to a deep plate; ladle wine-cream sauce over the top and garnish with chives.


  • Partner tip: Reynolds® Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

This recipe did not work well for me. The leeks turned out stringy and difficult to eat. I will purée the leftovers to use as a soup base. I probably won't try thi recipe again.

Chef John, as a complete freak of leeks this is a WONDERFUL recipe! The way it's made and the way it turns out is spectacular. It is the kind of dish you sit back after each bite and savor th...

This was sooo good! I didn't have the cream or pancetta, so I substituted plain Greek yogurt and bacon, and it was delicious. Next time I might cut the leeks into smaller pieces, just because ...

Perhaps not fair for me to give a review, since I really used this as a launching point and changed a lot... but it turned out great. I just used what I had on hand as substitutions. Swapped o...

I needed to use up some leeks I purchased for another recipe I did not use. Boy, am I glad that happened because this was great! Thanks Chef John!

I only had cheap Riesling wine and parmesan in a tub and it was still delicious! Even my husband who doesn't like veggies loved it!
