Wash the carrots and parsnips. Head a large pot of water until boiling and add the veggies for no more than 4-5 minutes. Drain them well until they are dry.
Heat the oven to 450 degrees and place the veggies and garlic on a baking sheet. Drizzle the vegetables with olive oil and sprinkle with salt. Toss to coat.
2 Tablespoons Olive Oil , 1 teaspoon Kosher Salt
Place the baking sheet in the oven, turning every 10-15 minutes until golden, about 35-40 minutes.
In a bowl whisk together the ingredients for the dressing. Set aside.
When the veggies are done, remove from the oven and drizzle with dressing. Squish the garlic cloves out of their peels and serve with the vegetables. Serve immediately.
