Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Peel and dice 2 medium carrots, 2 medium parsnips, and 2 medium sweet potatoes into 3/4-inch cubes. Toss with 3 tbsp olive oil, 1 tsp dried rosemary, 1/2 tsp salt, and 1/4 tsp black pepper on a sheet pan.
  2. Step 2: Roast for 25-30 minutes, stirring once halfway, until vegetables are tender and caramelized at edges.
  3. Step 3: While vegetables roast, whisk together 2 tbsp fresh lemon juice, 1 tsp Dijon mustard, 1 minced garlic clove, and 1/4 cup chopped fresh parsley in a small bowl until emulsified.
  4. Step 4: Transfer roasted vegetables to a serving dish and drizzle with 1/4 of the dressing. Toss gently until evenly coated, adding more dressing as needed to achieve a moist but not soggy texture.
  5. Step 5: Serve warm or at room temperature, garnished with additional parsley and a lemon wedge.
