Ingredients
  

For the Cauliflower
  • 1 large head cauliflower about 2 lbs, cut into 1.5-inch florets
  • 3 tbsp olive oil
  • 2 tbsp whole grain mustard
  • 1 tbsp Dijon mustard
  • 1 tsp honey
  • 2 cloves garlic minced
  • 0.75 tsp kosher salt
  • 0.5 tsp black pepper freshly ground
For Finishing
  • 2 tbsp fresh parsley chopped
  • 1 tsp lemon zest from 1 lemon

Equipment

  • Large Rimmed Baking Sheet
  • Large Mixing Bowl

Method
 

Prep
  1. Position a rack in the lower third of your oven and heat to 425F. Line a large rimmed baking sheet with parchment paper for easier cleanup.
  2. In a large bowl, whisk together the olive oil, whole grain mustard, Dijon mustard, honey, minced garlic, salt, and pepper until smooth and emulsified.
  3. Add the cauliflower florets to the bowl and toss thoroughly with your hands, rubbing the mustard mixture into every crevice. You want each piece well coated - this is where the flavor lives.
Roast
  1. Spread the cauliflower in a single layer on the prepared baking sheet, cut-side down where possible. Roast for 22-25 minutes, flipping once halfway through, until deeply golden at the edges and tender when pierced with a knife.
  2. Transfer to a serving platter and immediately scatter the chopped parsley and lemon zest over the hot cauliflower. The residual heat will wake up the herbs. Serve warm or at room temperature.

Notes

Don't overcrowd the pan or the cauliflower will steam instead of roast - use two sheets if needed. Whole grain mustard provides essential texture; don't substitute all Dijon. This dish holds beautifully at room temperature for an hour, making it ideal for buffets.
