1-Gathering and Prepping Your Ingredients: Start by gathering all your ingredients to make the process smooth. Begin with 1 tablespoon olive oil to sauté the onion, which adds a depth of flavor to your slow cooker butternut squash soup. Chop 1 medium yellow onion into 1/4- to 1/2-inch dice, about 1 1/2 cups total, and cook it in a saucepan over medium heat for 8 to 10 minutes until softened.

2-Gathering and Prepping Your Ingredients: Next, prepare the butternut squash by peeling, halving lengthwise, scooping out the seeds, and cutting 2 medium butternut squash (about 6 pounds total) into 3/4-inch cubes. Core and roughly dice 2 medium apples for that fruity sweetness. This step sets the foundation for a well-balanced slow cooker butternut squash soup.

3-Building and Cooking the Soup: Lightly coat a 4-quart or larger slow cooker with nonstick spray. Transfer the sautéed onion to the slow cooker, then add the cubed butternut squash and diced apples. Pour in 2 cups low-sodium vegetable broth or low-sodium chicken broth, along with 1 teaspoon salt, 1/2 teaspoon black pepper, 1/4 teaspoon nutmeg, and 1/4 teaspoon cayenne pepper if you want some heat.

4-Building and Cooking the Soup: Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours, until the squash and apples are tender. This slow cooking method brings out the best flavors in your slow cooker butternut squash soup, making it creamy without much effort.

5-Finishing and Serving: Once done, stir in 3/4 cup coconut milk to create that silky texture. Use an immersion blender to puree the soup right in the slow cooker, or blend in batches with a food processor or blender for a smooth consistency. Adjust thickness with more coconut milk if needed, and season to taste before serving hot with optional toppings.

6-Finishing and Serving: This step-by-step approach ensures your slow cooker butternut squash soup is just right, with tips like using frozen squash by adding it directly and extending cook time if necessary.
