Arugula Salad with Caramelized Onions, Goat Cheese, and Candied Walnuts

From the kitchen of Carly

Peppery arugula meets sweet caramelized onions, tangy goat cheese, and walnuts glazed in brown sugar and butter. Crispy bread cubes add textural contrast. This salad balances bitter, sweet, and savory in every bite.

Arugula Salad with Caramelized Onions, Goat Cheese, and Candied Walnuts

Deep, sticky caramelized onions and salty candied walnuts make this salad a proper main course. The trick is getting the onions past golden into mahogany territory, where they turn almost sweet. Croutons stay textured and crisp, goat cheese stays cold, and the whole thing balances acid, salt, and richness without tipping into heaviness.

Ingredients

4 servings

  • 2 tbspolive oil
  • 1 1/4 lbred onions, thinly sliced
  • 2 tbspbalsamic vinegar
  • 1/3 cupgolden brown sugar
  • 1/4 cupwater
  • 2 tbspbutter
  • 1 largepinch of salt
  • 1 1/2 cupwalnut halves
  • 4 cup1/2-inch cubes crustless country bread
  • 3 tbspextra-virgin olive oil
  • 5 tbspextra-virgin olive oil
  • 3 tbspbalsamic vinegar
  • 25-ounce packages baby arugula
  • 25-ounce packages soft goat cheese
  • 1broken into 1/2-inch pieces
  • 1chilled

Instructions

  1. Heat the oil in a heavy large skillet over medium-high heat. Drop in the onions and sauté until they turn golden, about 18 minutes. Pull from the heat. Shower with the vinegar and stir to blend. Season with salt and pepper.

  2. Combine the first 4 ingredients in another heavy large skillet. Bring to a boil while whisking continuously. Boil 1 minute. Add the walnuts and stir to coat. Toss until the syrup forms a glossy glaze on the nuts, about 3 minutes. Tip the candied nuts onto a sheet of foil and quickly separate with forks before they harden. Cool. (Holds 2 hours ahead at room temperature.)

  3. Bring the oven to 350°F. Drop the bread cubes into a large bowl, drizzle with oil, and toss constantly to coat evenly. Scatter the cubes in a single layer across a rimmed baking sheet and shower with salt and pepper. Bake until crisp, stirring occasionally, about 15 minutes. (The croutons hold 2 hours ahead on the sheet at room temperature.)

  4. In a small bowl, whisk the oil and vinegar together. Season the dressing with salt and pepper.

  5. Drop the arugula into a very large bowl. Add the onions and toss to distribute evenly. Scatter in the candied nuts, croutons, and goat cheese. Toss with enough dressing to lightly coat each leaf.

Tips from the kitchen

  • Caramelize the onions low and slow, at least 20 minutes. Don't rush this. They need time to break down and concentrate their natural sugars before the balsamic hits them.
  • When making candied walnuts, separate them with forks right after they come off heat while the glaze is still warm. Clumped walnuts are sad walnuts.
  • Make the croutons and candied nuts up to 2 hours ahead and leave them uncovered at room temperature so they stay crisp. Assemble the salad just before serving so arugula doesn't wilt.

Variations

  • Skip the croutons and add shaved Parmesan for a lighter, more delicate salad.
  • Swap the goat cheese for crumbled blue cheese or aged cheddar if you want a sharper, more savory angle.
  • Toast some pecans instead of walnuts and use apple cider vinegar in the dressing for a fall-leaning version.
  • Add shredded roasted beets for color and earthiness, and reduce the walnuts to 3/4 cup so the salad stays balanced.

Make ahead and storage

Keep leftovers in the fridge for up to 1 day, but eat it the same day if you can. Arugula doesn't hold up well, and the croutons go soft. The candied walnuts and caramelized onions stay good for 3 to 4 days in separate containers.
