Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F (low heat setting). Toss 3 medium peeled and chopped carrots, 2 medium peeled and chopped parsnips, and 2 medium peeled and cubed potatoes with 3 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper in a large bowl until evenly coated.
  2. Step 2: Spread vegetables in a single layer on a parchment-lined baking sheet. Roast uncovered at 300°F for 45 minutes, stirring gently with a spatula every 15 minutes to ensure even browning.
  3. Step 3: After 45 minutes, check for tenderness; vegetables should be fork-tender with golden-brown edges. Remove from oven and sprinkle with 1 tbsp fresh chopped thyme, tossing gently to distribute. Let rest for 5 minutes before serving to allow flavors to meld.
