  • Half Sheet Pan
  • Mixing Bowl


  • 1 pound Cauliflower Florets
  • 3 Tablespoons Olive Oil, divided
  • ½ teaspooon Kosher Salt
  • ¼ teaspoon Garlic Powder
  • 2 Tablespoons Shallots, diced
  • 2 Tablespoons Apple Cider Vinegar
  • 1 teaspoon Dijon Mustard
  • ½ teaspoon Honey
  • 1 Tablespoon finely chopped Parsley (optional)


  • Preheat oven to 425°F / 220°C.
  • Toss cauliflower florets with 2 Tablespoons olive oil, salt, and garlic powder. Spread out on a large sheet pan (be sure there is plenty of space between the florets so they will brown).
  • Roast cauliflower, without turning, until nearly tender, 15 minutes.
  • Remove cauliflower from the oven and use a flat spatula to gently flip the cauliflower.
  • Return cauliflower to oven and bake until very tender and golden 10 to 15 minutes more (cook time will vary slightly depending on the size of the florets).
  • When cauliflower is nearly finished, combine shallots, 1 Tablespoon olive oil, vinegar, mustard, and honey. Warm in the microwave just until bubbling, about 30 seconds.
  • Whisk parsley into vinaigrette.
  • When cauliflower is done roasting, gently toss with warm vinaigrette. Serve immediately.


Kosher Salt - I use Morton’s Kosher Salt to test recipes. If using table salt, reduce by about half. If using Diamond Kosher Salt, increase by about 25%. Everyone has their own preferences when it comes to salt, so be sure to taste and adjust as you go.
