Toss sweet potatoes, carrots, red onions, and parsnip with a little oil and herbs for an easy side dish. Roast them alongside chicken, pork loin, or beef.
Place potatoes, carrots, parsnip, and red onion in a 13x9x2-inch baking pan. Combine oil, garlic, mixed herbs, salt, and pepper in a small bowl. Drizzle over vegetables, tossing to coat.
Cover with foil. Bake in a 425 degree F oven for 30 minutes. Remove foil; stir vegetables. Bake, uncovered, for 5 to 10 minutes more or until vegetables are tender.
