Ingredients

• 2 large red onion
• 4 medium carrots
• 3 medium parsnips
• 1 large sweet potato
• 300 grams baby potatoes
• 3 tablespoons olive oil
• 2 sprigs fresh rosemary
• 2 sprigs fresh thyme
• 4 whole garlic cloves
• 1 teaspoon salt
• 0.5 teaspoon black pepper

Directions

Step 1

Preheat your oven to 220°C (425°F) and line a large baking tray with parchment paper.

Step 2

Peel the red onions and cut them into quarters. Set aside.

Step 3

Scrub the carrots, parsnips, and sweet potato (peeling if desired) and chop into evenly-sized chunks, about 2.5 cm (1 inch) in size.

Step 4

Halve the baby potatoes, or leave them whole if they are very small.

Step 5

In a large mixing bowl, combine the chopped vegetables and onions with olive oil, salt, black pepper, rosemary, thyme, and whole garlic cloves. Toss well to coat evenly.

Step 6

Spread the mixture onto the prepared baking tray in a single layer, ensuring the vegetables are not overcrowded (use an additional tray if necessary).

Step 7

Roast the vegetables in the preheated oven for 20 minutes, then remove the tray and gently toss the vegetables to ensure even roasting.

Step 8

Return the tray to the oven and roast for an additional 20 minutes, or until the vegetables are tender and caramelized at the edges.

Step 9

Remove from the oven and let the roasted vegetables cool for 5 minutes before serving.

Step 10

Serve warm as a side dish for roasted meats or as a standalone vegetarian meal.
