Romaine and Broccoli Salad

A good salad can be more than lettuce, tomato, and cucumber. This romaine and broccoli salad combines crisp Romaine leaves with a variety of fresh vegetables for texture, color, and flavor. It’s the type of salad that’s hearty enough to serve at a backyard gathering yet simple enough for a weeknight meal.

The base is torn Romaine hearts for a crisp, refreshing foundation. Added to that are small broccoli florets for crunch, thinly sliced mushrooms for earthiness, a pint of grape tomatoes for bright acidity, thin cucumber slices for coolness, and thinly sliced red onion for a touch of bite. All of these vegetables make the salad substantial and satisfying.

Romaine and Broccoli Salad with Creamy Roasted Garlic Dressing

The salad’s standout component is the creamy roasted garlic dressing. Roasting the garlic mellows its sharpness and adds a sweet, caramelized depth that pairs beautifully with mayonnaise and buttermilk. While roasting takes time, the hands-on work is minimal and the flavor payoff is significant. The dressing can be prepared ahead, which is convenient for entertaining.

How do you Roast Garlic?

To roast garlic, slice off the top 1/2 inch of each head so the cloves are exposed. Place each head cut-side up on a square of foil, season with salt and pepper, and drizzle with olive oil. Wrap each head securely in foil and roast directly on a rack in a 325°F oven until the cloves are very soft, about 70 minutes. When cool, the roasted cloves squeeze out easily into a soft, paste-like texture suitable for mixing into a dressing.

Once roasted and mashed, the garlic is whisked into mayonnaise, buttermilk, minced chives, lemon juice, celery salt, and a pinch of freshly ground black pepper to make the creamy roasted garlic dressing. Adjust seasoning to taste, and chill if preparing the dressing a day ahead.

Ingredients

Dressing:

  • 2 heads garlic, unpeeled
  • 1 tablespoon olive oil
  • 1 cup mayonnaise
  • ½ cup buttermilk
  • 2½ tablespoons minced fresh chives
  • 1 tablespoon freshly squeezed lemon juice
  • 1¼ teaspoons celery salt
  • ¼ teaspoon freshly ground black pepper

Vegetables:

  • 3 whole hearts of Romaine, torn into pieces
  • 1 pint grape tomatoes
  • 1½ cups small broccoli florets
  • 1 small English hothouse cucumber, thinly sliced
  • 8 ounces thinly sliced mushrooms
  • 1 small red onion, thinly sliced

Instructions

Roast the Garlic:

  • Preheat the oven to 325°F. Slice about ½ inch off the top of each head of garlic to expose the cloves. Place each head cut-side up on a square of foil, season with salt and pepper, and drizzle with olive oil. Wrap the garlic heads in foil and roast on an oven rack until tender, about 1 hour 10 minutes. Allow to cool before handling.

Prepare the Dressing:

  • Squeeze the roasted garlic cloves from their skins into a medium bowl and mash to a paste. Whisk in the mayonnaise, buttermilk, minced chives, lemon juice, celery salt, and black pepper until smooth and well combined. Taste and adjust seasoning. Chill the dressing if desired.

Assemble the Salad:

  • In a large bowl, combine the torn Romaine, grape tomatoes, broccoli florets, cucumber slices, mushrooms, and red onion. Add the dressing gradually, tossing gently until the salad is coated to your preference—you may not need to use all the dressing. Season with additional salt and pepper if needed and serve immediately.
