Why It Works

  • Roughly chopping the fennel fronds makes it easier for the blender to fully purée them.
  • Anchovies add a savory note, mustard and garlic add pungency, while fresh lemon brightens the sauce.

If you find yourself with leftover fennel fronds, you can whip up this easy sauce in no time. It's bright with fresh lemon juice and lemon zest, funky thanks to garlic and a touch of mustard, and savory due to a healthy dose of oil-packed anchovies. Feel free to vary it based on what you have and desire (skip the anchovies, add capers, use scallions or chives instead of garlic, etc.).

You can use this sauce a million ways: Dress vegetables with it, toss pasta in it, serve it with roasted or poached meats, dollop it on eggs or fresh cheeses, spread it on sandwiches, and more.
