Creamed Leeks are the best way to finish off any dish, whether it’s Pan-Seared Duck Breast or Bacon-Wrapped Stuffed Chicken.

What Are Creamed Leeks?

Leeks look a bit like big green onions, but they’ve got a milder flavor. The part you use is the white and light green bit at the bottom, and you can slice them up to add a subtle oniony taste to all sorts of dishes, like soups, salads, and even as a side dish.

These Creamed Leeks are a low-carb, keto-friendly side dish perfect for jazzing up any main dish, like our Steakhouse Keto Creamed Spinach. The leeks are sautéed in bacon fat, butter, heavy cream, and parmesan cheese for the ultimate indulgent delight.

Creamy Leeks Ingredients

  • Leeks – provide a mild, sweet, and slightly mellow onion flavor.
  • Bacon – adds a smoky flavor that compliments the savory sweetness of the leeks.
  • Onion – enhances the aromatic base of the dish and provides a mild pungency and depth of flavor.
  • Butter – helps create a velvety sauce that coats the leeks and adds a luscious, silky mouthfeel.
  • Garlic cloves – add a robust, aromatic, and slightly spicy note to the dish.
  • Mustard powder – brings a subtle tang and an additional layer of flavor to the creamed leeks.
  • Heavy cream – combines with the butter to form a luscious, thick sauce that envelops the leeks and imparts a rich, creamy taste.
  • Parmesan cheese – adds a salty, nutty, and slightly tangy flavor to the dish.
  • Freshly grated nutmeg
  • Kosher Salt and freshly ground black pepper to taste
  • Lemon zest

How to Make This Easy Creamed Leeks Recipe

  • First, trim the leeks using a sharp knife, removing just the darker green parts, and slice them thin. We’ll need those tender parts.
  • Now, grab a big cast iron skillet and cook up the bacon over medium heat until it’s just perfectly crispy. Once it’s ready, set the bacon aside on a paper towel-lined plate.

Pro Tip: Don’t forget to clean and season your cast iron skillet before cooking to ensure maximum flavor. 

  • Next, toss in your chopped onions and sliced leeks in that same skillet. Don’t forget to add a tablespoon of butter for extra flavor. Now, sauté those leeks and onions until they turn soft and lovely, which should take about 5 to 7 minutes.
  • Time to add in the garlic and give it a quick sauté, just for about 30 seconds. Then sprinkle in the mustard powder, a pinch of salt, and a bit of pepper. Give it all a good stir to mix the flavors.
  • Now, let’s lower the heat to medium-low and pour in the heavy cream and cheese. Stir everything together and let the sauce thicken up. This will take about 5 to 7 minutes.
  • When the sauce is all creamy and ready, take the skillet off the heat. Add a pinch of freshly grated nutmeg. Chop up the bacon you cooked earlier and fold it back into the leek mixture.
  • To finish off, add a little pinch of lemon zest for a zesty pop, and your creamy leeks are good to go. Season with a pinch of salt and pepper. They’re amazing on their own but even better with a handful of crispy onions on top. Enjoy!

Look for leaks that don’t have a ton of layers of leaves, as these will get discarded before cooking. Try to find leeks around the same size with a decent amount of light green and yellowish-white on the bottom.
