Cuisine: American
Servings: 6 servings

Ingredients

  • 1 large head cauliflower about 2 to 2 ½ lbs.
  • 1 ½ Tbsp. oil olive or avocado
  • 1 ¼ tsp. salt divided, to taste
  • ½ tsp. black pepper to taste
  • cup mayonnaise
  • 1 Tbsp. mustard yellow
  • ¼ cup dill pickle relish
  • ¼ cup white onion finely diced
  • ¼ cup celery finely diced
  • 2 hard-boiled eggs chopped

Instructions

  • Preheat the oven to 425 degrees.
  • Remove the stem and leaves from the head of cauliflower and cut into ½-inch bite-sized pieces. You should end up with roughly 1 ½ to 1 ¾ lbs. of cauliflower florets.
  • Add these to a large bowl and drizzle with the oil and sprinkle with ¾ teaspoon of salt and ¼ teaspoon of black pepper. Toss until the cauliflower is well coated.
  • Spread the cauliflower out onto a parchment paper lined baking sheet in a single layer. Bake in the preheated oven for 20 minutes, flipping halfway through.
  • While the cauliflower is baking, wipe out the large bowl if any pieces of cauliflower remain. Then add the mayonnaise, mustard, relish, ½ teaspoon of remaining salt, and ¼ teaspoon of remaining pepper. Whisk together until well combined.
  • When the cauliflower is roasted, let it cool to room temperature. Once cooled, add it to the large bowl with the mayonnaise dressing along with the diced onion, celery, and hard-boiled eggs. Mix everything together until just combined. Serve immediately with a sprinkle of chopped fresh dill or place in the refrigerator for a couple of hours to serve chilled.
