Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Peel and cube the butternut squash into 1-inch pieces, core and chop the apple, and roughly chop the yellow onion.
Place the squash, apple, and onion on the baking sheet, then drizzle with the extra virgin olive oil.
Sprinkle the sea salt, black pepper, ground cinnamon, and dried thyme over the produce and toss until evenly coated.
Spread the mixture in a single layer on the baking sheet to ensure even roasting.
Place the chicken breast in a separate small oven-safe dish and season lightly with a pinch of salt and pepper.
Roast the vegetables and apple for 25-30 minutes until the squash is fork-tender and the edges are slightly caramelized.
Roast the chicken simultaneously for 20-25 minutes, or until the internal temperature reaches 165°F.
Transfer the roasted squash, apple, and onion mixture into a high-speed blender and add the warm chicken bone broth.
Process on high until the soup reaches a completely smooth and velvety consistency.
Dice or shred the roasted chicken breast and serve it directly on top of the warm soup.
