Preheat the Oven: Start by preheating your oven to 425°F (220°C). This will ensure a crispy outside and tender inside for your vegetables!
Prepare the Vegetables: In a large bowl, combine the chopped potatoes, sliced carrots, parsnip pieces, red onion wedges, and minced garlic.
Season Generously: Drizzle with olive oil and season with salt and pepper. If desired, add dried herbs to elevate the flavors. Toss everything together until the veggies are well coated.
Spread on a Baking Sheet: Pour the vegetable mixture onto a large baking sheet, spreading them out into a single layer for even roasting.
Roast to Perfection: Place the baking sheet in the preheated oven and roast for 25-30 minutes. Stir halfway through so they cook evenly. The vegetables should be golden brown and tender when finished.
Serve and Enjoy: Take them out, let them cool slightly, and serve warm alongside your favorite main dish or enjoy them as a standalone treat!
