Instructions

Preheat the oven to 400°F

Set your oven to 400°F (200°C) to ensure it reaches the ideal temperature by the time you finish prepping. This temperature allows the vegetables to roast evenly and develop a nice caramelized exterior.

Prepare the vegetables

Cut the sweet potatoes and carrots into roughly 3/4-inch to 1-inch pieces for even cooking. Keeping the sizes uniform ensures the vegetables roast evenly and become tender simultaneously.

Toss with garlic, oil, and seasonings

Place the cut vegetables in a large baking dish. Add minced garlic, olive oil, maple syrup, thyme, rosemary, cinnamon, and salt. Toss thoroughly so each piece is well-coated, which helps with flavor absorption and caramelization.

Roast the vegetables

Put the baking dish in the preheated oven for 35–40 minutes. Remember to toss the vegetables halfway through roasting to ensure even browning and caramelization on all sides.

Check for tenderness and serve

The vegetables should be lightly browned, caramelized, and easily pierced with a fork. Remove from the oven and serve while hot to enjoy their full flavor and texture.

You Must Know

  • Leftover roasted veggies keep well in an airtight container for 3-5 days and reheat nicely.
  • Feel free to swap the orange sweet potatoes with Japanese sweet potatoes or butternut squash.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to 5 days. Reheat in the oven to preserve texture or use the microwave for a quicker option with good results.

Serving Suggestions

FAQs

Can I use fresh herbs instead of dried?

Yes, you can swap dried thyme and rosemary for fresh. Use about three times the amount when using fresh herbs for an optimal flavor.

How do I prevent the vegetables from sticking?

Make sure to toss the vegetables well with olive oil before roasting. Using a non-stick baking dish or parchment paper also helps prevent sticking.

Can I roast these vegetables in advance?

Yes, roast them a day ahead and store in the fridge. Reheat in the oven to bring back their crispy edges and warmth.

Are these vegetables suitable for a vegan diet?

Absolutely! All ingredients used are plant-based, making this dish a perfect vegan side.

Can I add other spices?

Feel free to experiment by adding spices like smoked paprika or cumin to give the dish a different flavor profile.

What is the best way to reheat leftovers?

Reheat in a preheated oven at 350°F until heated through to maintain crispness, or use a microwave for convenience if texture is not a top priority.
