12 ounces apples – cored, cut into 0.75-inch-thick wedges
8 ounces red onion – peeled, cut into 0.5-inch-thick wedges
3 tbsp olive oil
1 tbsp maple syrup
1 tsp fresh thyme – leaves stripped and chopped
1.25 tsp kosher salt
0.5 tsp black pepper
Instructions
Heat the oven to 425°F and line a large rimmed baking sheet with parchment paper.
Prep the vegetables: Halve and seed the delicata squash, then slice into 0.5-inch-thick half-moons; core the apples and cut into 0.75-inch-thick wedges; peel the red onion and cut into 0.5-inch-thick wedges.
In a large bowl, toss the prepared pieces with the olive oil, maple syrup, fresh thyme, kosher salt, and black pepper until evenly coated. Spread in a single layer on the baking sheet, leaving a little space between pieces.
Roast, stirring once halfway, until the vegetables are tender and edges are caramelized, 20–25 minutes; they’re done when a knife slides easily through the squash and the surfaces show browned spots. Serve warm.
