Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the cubed butternut squash, chopped apple, and diced onion with olive oil, sea salt, black pepper, and dried thyme.
Spread the mixture in a single layer on the baking sheet and roast for 25 to 30 minutes until the squash is fork-tender and lightly caramelized.
While the vegetables roast, season the chicken breast with a pinch of salt and pepper, then bake or pan-sear until it reaches an internal temperature of 165°F.
Allow the chicken to cool slightly, then use two forks to shred it into bite-sized pieces.
Transfer the roasted squash mixture and the minced garlic into a high-speed blender along with the chicken bone broth and ground cinnamon.
Blend on high until the soup is completely smooth and velvety in texture.
Pour the soup into a bowl, stir in the shredded chicken, and serve warm.
