Ingredients

  • 2 medium parsnips, peeled and diced
  • 3 medium potatoes, peeled and cubed
  • 1 large sweet potato, peeled and cubed
  • 1 medium turnip, peeled and diced
  • 1 large onion, chopped
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • 1/2 teaspoon smoked paprika
  • Salt and black pepper, to taste
  • 1 cup vegetable broth
  • 1/2 cup coconut milk (or heavy cream for non-vegan)
  • 2 tablespoons all-purpose flour (or gluten-free flour)
  • Fresh parsley, chopped for garnish
  • Optional: 1 cup grated vegan cheese or regular cheese

Equipment

  • Large mixing bowl
  • Sharp knife and cutting board
  • Large casserole dish (about 9×13 inches)
  • Measuring cups and spoons
  • Large skillet or sauté pan
  • Wooden spoon or spatula
  • Oven mitts

Instructions

  1. Preheat your oven to 375°F (190°C). Grease your casserole dish lightly with olive oil or non-stick spray.
  2. Prepare the root vegetables: Peel and chop the carrots, parsnips, potatoes, sweet potato, and turnip into bite-sized pieces. Place them in a large mixing bowl.
  3. Add the onion and garlic to the bowl. Drizzle with olive oil and sprinkle with dried thyme, rosemary, smoked paprika, salt, and pepper. Toss everything together until well coated.
  4. Transfer the seasoned vegetables to the prepared casserole dish, spreading them out evenly.
  5. In a skillet over medium heat, add a tablespoon of olive oil. Stir in the flour and cook for 1-2 minutes to create a roux, stirring constantly.
  6. Slowly whisk in the vegetable broth and coconut milk, continuing to stir until the sauce thickens, about 3-4 minutes. Season with salt and pepper to taste.
  7. Pour the creamy sauce evenly over the vegetables in the casserole dish.
  8. Optionally, sprinkle grated cheese over the top for a golden crust.
  9. Cover the casserole with foil and bake in the preheated oven for 45 minutes.
  10. Remove the foil and continue baking for another 15-20 minutes until the top is golden and vegetables are tender when pierced with a fork.
  11. Garnish with fresh parsley before serving.

Tips & Variations

“To add extra flavor and texture, try roasting the root vegetables separately before assembling the casserole. This caramelizes their natural sugars and brings out a deeper taste.”

  • Make it vegan: Use coconut milk or any plant-based cream and vegan cheese alternatives.
  • Add greens: Stir in chopped kale or Swiss chard for added color and nutrients. See more ideas in our Vegetarian Swiss Chard Recipes for Healthy Meals.
  • Spice it up: Add a pinch of cayenne or chili flakes for a subtle heat.
  • Bulk it up: Mix in cooked lentils or chickpeas for added protein.
  • Herbs: Fresh herbs like thyme, rosemary, and sage bring out the earthy flavors of root vegetables beautifully.
