Preheat oven to 400 degrees. Grease a baking sheet with cooking spray and set aside.
Peel butternut squash. Cut in half. Scoop seeds out and cut into ½" cubes. Spread cubes on baking sheet and drizzle with olive oil. Sprinkle with 1 teaspoon salt, ¼ teaspoon pepper, cinnamon, and garlic powder. Toss with hands until evenly coated. Bake at 400 degrees for 20 minutes.
While squash is cooking, cut broccoli into bite sized florets. Once squash has cooked for 20 mins, remove from oven and stir in broccoli. Season with additional ¼ teaspoon salt and ¼ teaspoon pepper. Toss to coat in juices from pan. Return to oven and bake additional 15-20 minutes until broccoli reaches desired tenderness (I prefer crisp tender so I cooked for 15 mins).
Remove from oven and serve warm.
