Equipment

  • 2 Baking sheets, lined with parchment paper
  • 1 Sharp chef’s knife
  • 1 Small Saucepan
  • Mixing bowls (1 or 2, medium size)
  • Serving platter

Ingredients
  

  • 2 medium beets preferably one red and one golden, peeled and cut into 1-inch pieces
  • 1 large carrot sliced into 1-inch rounds
  • 3 parsnips peeled and chopped into 1-inch chunks
  • 1 medium sweet potato peeled and diced into 1-inch pieces
  • 1 turnip peeled and chopped into 1-inch pieces
  • Extra-virgin olive oil for drizzling
  • 1 tablespoon fresh rosemary finely chopped
  • 1 tablespoon fresh sage leaves chopped
  • 1 tablespoon fresh thyme leaves
  • Sea salt to taste
  • Freshly ground black pepper to taste

For the Sage Garnish and Oil:

  • 2 tablespoons extra-virgin olive oil
  • 10 fresh sage leaves

Instructions
 

  • Prepare Oven and Vegetables: Preheat your oven to 425°F (220°C). Line two large baking sheets with parchment paper to prevent sticking and ease cleanup. Separate the root vegetables into two groups: place beets and carrots on one baking sheet, and parsnips, sweet potato, and turnip on the other. This helps manage their different cooking times.
  • Season and Toss Vegetables: Drizzle the vegetables generously with olive oil. Sprinkle chopped rosemary, sage, and thyme evenly over them. Season with sea salt and freshly ground black pepper to taste. Toss everything together with your hands or a spatula to ensure each piece is well-coated with herbs and oil. Spread the vegetables out evenly in a single layer on the baking sheets.
  • Roast Vegetables Until Tender: Place both baking sheets in the preheated oven. Roast the parsnips, sweet potato, and turnip for about 25 to 35 minutes, until tender and lightly browned. The beets and carrots will need a longer roasting time—about 45 to 50 minutes—to become soft and caramelized. Check occasionally and stir gently to ensure even cooking.
  • Prepare Crispy Sage and Sage Oil: While the vegetables roast, heat 2 tablespoons of olive oil in a small saucepan over medium heat until shimmering. Add the fresh sage leaves and cook, stirring gently, for about 1 minute or until the leaves turn crisp but not burnt. Remove the leaves with a slotted spoon and place them on paper towels to drain excess oil. Keep the infused olive oil for drizzling over the finished dish.
  • Final Toss and Serve: Once the vegetables are tender and golden, remove them from the oven. Transfer the veggies to a large bowl or serving platter. Drizzle with about one tablespoon of the sage-infused olive oil and toss gently to coat. Top with the crispy sage leaves for a beautiful, flavorful finish. Serve warm.

Notes

  • Vegetable Variations: Feel free to swap in other root vegetables like rutabaga or sweet onions based on availability or preference.
  • Even Cooking Tip: Because some vegetables roast faster than others, separating them onto two trays ensures everything cooks perfectly without burning or undercooking.
  • Make Ahead: You can prepare the vegetables a day ahead and keep them refrigerated, then roast fresh before serving.
  • Storage: Leftover roasted vegetables keep well in an airtight container in the refrigerator for up to 4 days. Reheat in the oven to restore crispness.
  • Vegan & Gluten-Free: This recipe is naturally free from animal products and gluten, making it suitable for many dietary preferences.

    Chef’s Secrets for Flavorful Roasting

    Achieving perfectly roasted root vegetables is all about layering flavors and controlling cooking times.

    Start by cutting the vegetables into uniform 1-inch pieces; this ensures even cooking and consistent caramelization.

    Separating the vegetables onto two baking sheets based on their cooking time prevents some from overcooking while others are underdone.

    Using fresh herbs like rosemary, sage, and thyme enhances the earthy sweetness naturally found in root vegetables, while the sage-infused oil and crispy sage leaves add a sophisticated aromatic finish that elevates the dish.

    Don’t rush the roasting process—allowing the veggies enough time to brown around the edges is key for developing depth and texture.

    Lastly, tossing the vegetables with sage oil right after roasting locks in moisture and flavor, making every bite luscious and fragrant.

    Serving Suggestions for Maximum Enjoyment

    This dish pairs beautifully with a variety of mains.

    It’s an excellent accompaniment to roasted meats like turkey, chicken, or pork, especially during holiday meals.

    For a plant-based feast, serve alongside grain bowls, lentil stews, or stuffed squash for a hearty and nutritious plate.

    To add contrast, pair the sweet and earthy veggies with tangy elements like a balsamic glaze or a dollop of vegan yogurt or crème fraîche.

    Garnish with extra crispy sage leaves or toasted nuts for crunch.

    This recipe also works great as a warm salad base topped with fresh greens or a drizzle of zesty citrus vinaigrette, making it a versatile addition to any meal.

    Storage Tips to Maintain Freshness

    Roasted root vegetables store well and make great leftovers, perfect for quick meals.

    Allow the vegetables to cool completely before transferring them to an airtight container.

    Store them in the refrigerator for up to four days.

    To reheat, warm them gently in a preheated oven at 350°F (175°C) for 10-15 minutes to revive their crisp edges and fresh flavors—avoid microwaving, which can make them soggy.

    The sage oil and crispy sage leaves are best made fresh but can be stored separately in a small container in the fridge for a day or two.

    If you want to meal prep, keep the roasted veggies and garnish separate until serving.

    Frequently Asked Questions (FAQs) Answered

    1. Can I use frozen root vegetables?

    Frozen root vegetables can be used, but fresh is best for roasting. Frozen veggies tend to release more moisture, which can result in steaming rather than roasting, so expect a softer texture.

    2. How do I prevent the vegetables from sticking to the baking sheet?

    Using parchment paper or a silicone baking mat is key to preventing sticking. Additionally, toss the vegetables in enough olive oil and spread them out in a single layer without overcrowding to allow air circulation.

    3. Can I prepare the crispy sage leaves ahead of time?

    Crispy sage leaves are best prepared just before serving to maintain their texture and flavor. If made ahead, they may lose crispness and become soggy.

    4. Is this recipe suitable for meal prepping?

    Yes! The roasted vegetables store well and reheat beautifully in the oven, making them a convenient option for preparing meals in advance.

    5. Can I substitute other herbs for rosemary, sage, or thyme?

    Certainly! Herbs like oregano, marjoram, or tarragon can be used based on your preference. Keep in mind that sage has a distinct earthy flavor, so substituting it might change the dish’s overall aroma.
