🍽 Ingredients

📖 Instructions

  1. Preheat your oven to 400°F (200°C). This is crucial for achieving that perfectly roasted texture—tender on the inside, beautifully crisp on the outside.
  2. Wash and prep your vegetables: Give your carrots, potatoes, and parsnips a good scrub. Peel them if you like, but I often leave the skins on for extra flavor and nutrients. I mean, unless they're really dirty, of course!
  3. Chop the vegetables: Cut the carrots, potatoes, and parsnips into roughly 1-inch pieces. Try to make them relatively uniform in size to ensure even cooking. Think of it as a tiny vegetable army marching to their delicious destiny!
  4. Toss with olive oil and herbs: In a large bowl, toss the chopped vegetables with 2-3 tablespoons of olive oil. Add 1-2 teaspoons of dried rosemary, 1-2 teaspoons of dried thyme, salt, and pepper. Feel free to get creative with your seasonings! I sometimes add a pinch of garlic powder for extra zing. Give everything a good toss to make sure the vegetables are evenly coated.
  5. Spread on a roasting pan: Spread the vegetables in a single layer on a large roasting pan. Don't overcrowd the pan, or they’ll steam instead of roast. If you need more space, use two pans, no problem!
  6. Roast: Roast for 40-45 minutes, or until the vegetables are tender and slightly caramelized. Flip them halfway through for even browning. The kitchen will start to smell AMAZING at this point, just warning you.
  7. Check for doneness: To check if they’re done, pierce a vegetable with a fork. If it easily goes through, they’re ready. If not, give them a little more time in the oven.
  8. Optional: Broil for extra crispiness (optional): If you want extra crispy edges, broil for the last 2-3 minutes, keeping a close eye to prevent burning. I know this is risky, but the rewards are worth it, sometimes! Just don't walk away.
  9. Serve and enjoy!: Once roasted, transfer the vegetables to a serving bowl. You can drizzle with a little extra olive oil and sprinkle with fresh herbs before serving. Perfect as a side dish, or even as a hearty vegetarian meal!

📝 Notes

  • For extra flavor, try adding a pinch of garlic powder or onion powder.
  • If you like a crispier texture, you can roast the vegetables at a slightly higher temperature (425°F or 220°C).
  • Don't be afraid to experiment with different herbs and spices!
