Heat olive oil in a Dutch oven over medium-high. Add the onion and garlic and sauté, stirring occasionally, for 5 minutes. Add the butternut squash and cook another 2 minutes.
Mix together the spices, then sprinkle over the vegetables in the pot. Stir well to coat and cook for 1 minute, until fragrant. Add a small amount of the broth and scrape up any browned bits from the bottom of the pot.
