Preheat your oven to 425°F (220°C) to ensure even cooking and caramelization.

Core and chop the selected apples into ½” cubes, cut the carrots diagonally into ¼” thick slices, dice the onion, and finely chop the garlic. Set aside.

In a large bowl, whisk together olive oil (or aquafaba), maple syrup, stone ground Dijon mustard, salt, black pepper, and thyme.

Add the chopped apples, carrots, diced onion, and garlic to the bowl with your glaze. Toss until well-coated.

Spread the glazed vegetable mixture evenly onto a metal baking pan in a single layer.

Place the pan in the preheated oven and roast for 15 minutes. Flip the contents for even browning, then continue roasting for an additional 10-15 minutes, or until tender and caramelized.
