Ingredients for One-Pan Dijon Mustard Glazed Chicken Breast with Roasted Cauliflower and Broccoli

Instructions

Preheat the oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper or aluminum foil for easy cleanup.
In a small bowl, whisk together Dijon mustard, honey, minced garlic, smoked paprika, 1 tablespoon olive oil, salt, black pepper, and crushed red pepper flakes (if using) to create the glaze.
Pat the chicken breasts dry with paper towels and place them in a single layer on the prepared baking sheet.
Brush each chicken breast generously with the Dijon mustard glaze on all sides, reserving any remaining glaze.
In a large bowl, toss the cauliflower and broccoli florets with the remaining 2 tablespoons olive oil, then season with a pinch of salt and pepper.
Arrange the vegetables evenly around the chicken breasts on the baking sheet, avoiding overcrowding to ensure even roasting.
Roast in the preheated oven for 20 minutes.
Remove the baking sheet, brush the chicken breasts with the remaining glaze, and gently toss the vegetables to turn them.
Return the baking sheet to the oven and roast an additional 5 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender with slight caramelization.
Remove from the oven and let the chicken rest for 5 minutes before slicing.
Garnish with chopped fresh parsley and serve warm with lemon wedges, if desired. Enjoy!
