Why We Love This Recipe For Salad with Fiddlehead Ferns

Along with the fiddleheads in this beautiful salad, the other big treat: garlicky marinated mushrooms. This dish could be served alongside any type of protein (I love it with grilled steak or fish) or any other side for a festive dinner or get-together in the spring.

Fiddleheads are the tightly wound curls of ferns when they first emerge out of the ground each spring and before they unfurl to become big waving leafy ferns. They taste like crunchy asparagus with a little nuttiness.

Recipe Highlights

  • A great way to serve fiddleheads when/if you have them
  • Easy and foolproof to make.
  • Recipe is easily doubled to serve a crowd

Key Ingredients For This Recipe

  • Baby Bella or Cremini Mushrooms: These mushrooms can be used interchangeably in this salad. Their marinade serves as the dressing for the whole shebang.
  • Pantry Staples: Kosher salt, black pepper, garlic, extra-virgin olive oil, red wine vinegar. (See my guide to vinegar for substitution ideas.)
  • Fresh Rosemary: Use a 1/2 teaspoon dried if you don’t have fresh.
  • Baby Spinach: You could also use a mix of spring greens.
  • Fiddlehead Ferns: You can buy them at good produce markets in the spring. So if you’re not cool enough to be into foraging (I’m totally not cool enough to forage in case you were wondering) then you can just buy them. If you can’t find fiddleheads, use chopped asparagus instead.
  • Swiss Cheese: You’ll need a block of Swiss cheese so that you can cut it into little cubes. Use cheddar if you prefer.

Step-by-Step Instructions to Make This Fiddlehead Salad

Step 1: Cook mushrooms

Place the mushrooms in a medium dry saucepan, then cover and place over medium heat. Cook, without peeking, shaking the pan occasionally until the mushrooms squeak when you shake the saucepan, 5 to 8 minutes. Turn off the heat and let sit covered, undisturbed for 10 minutes. Add olive oil, vinegar, garlic, rosemary, ½ teaspoon salt and pepper, and stir to coat. Let cool.

Step 2: Blanch fiddleheads

Meanwhile, bring a medium saucepan of salted water to a boil. Add fiddleheads and cook until crisp-tender, 3 to 4 minutes. Drain and rinse with cold water. Drain thoroughly.

Step 3: Arrange fiddlehead salad

Arrange greens in a salad bowl. Add fiddleheads and Swiss cheese. Add mushrooms and marinade and toss to combine.
