Instructions

1. 1

   Prepare the tray

   Heat the oven to 220°C (425°F). Line a 38 × 51 cm (15 × 20-inch) rimmed baking tray with foil and coat it with non-stick cooking spray.

2. 2

   Season the vegetables

   Put all the prepared vegetables in a large bowl. Add the olive oil, thyme, oregano, parsley, garlic powder, salt, pepper and cumin, then toss until evenly coated.

3. 3

   Make two flavours

   Divide the vegetables evenly between two bowls, reusing the first bowl if convenient. Add 45 ml (3 tablespoons) balsamic vinegar and 15 ml (1 tablespoon) maple syrup to one bowl and toss. Add ½ cup of the grated Parmesan to the other bowl and mix well.

4. 4

   Roast the vegetables

   Arrange the vegetables in a single layer on the prepared tray, keeping the two flavours separate. Roast for 40–50 minutes, turning and stirring the vegetables halfway through, until fork-tender.

5. 5

   Finish the maple vegetables

   Take the tray out of the oven. Toss the maple balsamic vegetables with the remaining 15 ml (1 tablespoon) balsamic vinegar and 5 ml (1 teaspoon) maple syrup.

6. 6

   Finish and serve

   Drizzle the Parmesan herb vegetables with the melted butter, if using, and scatter over the remaining 2 tablespoons of Parmesan. Toss to coat, adjust the salt and pepper to taste, and serve warm.

What are roasted root vegetables?

Roasted root vegetables are a familiar American side dish, especially at autumn and holiday meals. This version combines carrots, sweet potatoes, parsnips, squash and red onion, then gives the tray two distinct finishes.

The maple balsamic half is sweet and tangy, while Parmesan, garlic and dried herbs make the other half savoury and aromatic. Dividing the vegetables after seasoning lets both flavours roast together without blending.

Nutrition and macros by portion

The nutrition label shows one serving as written: 174 calories, 5g protein, 29g carbs, 8g fat.

The sweet potatoes, carrots, parsnips and squash provide most of the carbohydrates, while olive oil, Parmesan and optional butter contribute much of the fat. Parmesan also supplies some protein, though this side is best balanced with a protein-rich main and a green vegetable or salad.

Why cut the vegetables evenly?

Even pieces: aim for roughly 4 cm chunks so the different vegetables have a better chance of becoming tender at about the same time. Smaller pieces may soften sooner, while large pieces can need longer in the oven.

Dry surfaces: if the vegetables are wet after washing, pat them dry before adding the oil. This helps the seasoning cling and encourages roasting rather than steaming.

How to get two flavours on one tray

Keep the halves apart: toss the vegetables with their respective flavourings in separate bowls, then arrange each mixture on its own side of the tray. Leave a small gap between them to make serving easier.

Save some for the end: the recipe adds extra vinegar and syrup to the maple vegetables after roasting, and Parmesan and butter to the other half. These finishing additions keep the two profiles distinct.

Roasting for tender, browned vegetables

Single layer: spread the pieces out rather than piling them up. If the tray is crowded, use a second tray so the vegetables can roast and brown more evenly.

Doneness: begin checking around 40 minutes. A fork should slide into the thickest pieces with little resistance; continue roasting towards 50 minutes if they are still firm.

Timing and tray management

The stated total time is 65 minutes, including preparation and roasting. Cutting the vegetables into similarly sized chunks and mixing the two flavourings while the oven heats helps the work run smoothly.

At the halfway point, turn the vegetables and keep the two groups separate. The edges may brown at different rates, so check tenderness rather than relying only on the clock.

Choosing the finishing ingredients

Maple and balsamic: maple syrup rounds out the vinegar’s sharpness, while the extra drizzle after roasting refreshes that sweet-tart flavour. Use pure maple syrup as specified for this combination.

Parmesan and herbs: freshly grated Parmesan melts and clings more readily than larger pre-grated pieces. Butter is optional, but adds richness to the savoury half.

What to serve alongside

These vegetables work well beside roast turkey, chicken or a vegetarian main, and the two finishes offer variety on one platter. For a more substantial plate, add a protein-rich main and a crisp green salad.

Serve them warm soon after the finishing ingredients are added. A simple grain or bread can round out the meal and make use of any savoury juices on the plate.

Recipe notes & tips

• Use a large bowl so you can coat the vegetables evenly without spilling.
• Cut the vegetables into pieces of similar size for more even cooking.
• Grate the Parmesan finely so it spreads evenly through its half of the tray.
• Keep the two groups separate while tossing and turning them.
• Check the thickest pieces with a fork before taking the tray out.
• Taste before serving and add salt or pepper only as needed.

Variations

• Add rosemary: swap in a little dried rosemary for some of the thyme.
• Use fresh herbs: finish with chopped parsley after roasting for a fresher flavour.
• Make it dairy-free: leave out the Parmesan and butter, and serve the savoury vegetables with extra herbs.
• Add chilli: scatter a pinch of chilli flakes over either half before roasting.
• Try pecorino: replace the Parmesan with finely grated pecorino for a sharper finish.

Common mistakes to avoid

• Crowding the tray: the vegetables may steam instead of roast; use two trays if needed.
• Uneven chopping: pieces cook at different rates; cut them to a similar 4 cm size.
• Mixing the flavour groups: their finishes can blur together; leave a clear gap between them.
• Skipping the halfway turn: the undersides may stay pale; stir and turn the vegetables midway.
• Adding all the finishing ingredients too early: the final flavours can become less distinct; follow the finishing steps after roasting.

How to store

Cool leftovers promptly and refrigerate in an airtight container for up to 3 days. Reheat in a 180°C oven until hot, or use a microwave; the oven helps the vegetables regain some of their roasted texture.
