Detailed Directions and Instructions
Preheat Oven
Set the oven to 425°F (218°C).
Roast Soup Vegetables
Arrange the sweet potatoes and red onion on a baking sheet. Drizzle with 2 tablespoons of oil and sprinkle with 1 teaspoon of salt. Roast for 30-45 minutes until they are golden brown and softened.
Roast Cauliflower
On a separate baking sheet, toss the cauliflower florets with 1 tablespoon of oil and 1 teaspoon of salt. Roast in the oven for 30 minutes.
Crumble Cauliflower
After roasting, break the cauliflower into smaller pieces using the back of a wooden spoon or spatula. Return to the oven for an additional 10-15 minutes to achieve extra browning.
Blend Soup
Once the sweet potatoes and onions have cooled slightly, transfer them to a blender in batches. Add the vegetable broth, fresh ginger, and macadamia nuts or cashews. Blend until the mixture is very smooth.
Serve
Taste the soup and adjust the seasoning with additional salt if necessary. Serve the soup topped with the roasted cauliflower crumbles, chopped chives, a drizzle of infused oil, and a squeeze of lemon juice.
Notes
Consistency
For a thicker soup, reduce the amount of vegetable broth, or for a thinner soup, add more broth until the desired consistency is achieved.
Storage
Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently before serving.
Customization
Feel free to experiment with different toppings or spices according to personal preference, such as adding crushed red pepper flakes for extra heat.
Nuts Substitute
If you or someone you’re serving has a nut allergy, you can omit the nuts or replace them with a seed like pumpkin seeds for added texture.
Cook techniques
Roasting Vegetables
Roasting brings out the natural sweetness and enhances the flavors of sweet potatoes and red onions. Ensure they are cut into even chunks for uniform cooking. Use a drizzle of oil and seasoning to elevate their taste.
Blending for Smoothness
When blending the roasted vegetables, make sure not to overfill the blender. Blend in batches if necessary to achieve a creamy, smooth consistency. Adding vegetable broth gradually helps in reaching the desired texture without the mixture becoming too thick.
Flavor Balancing
Taste the soup after blending to determine if it needs any additional salt or seasoning. Consider adding a squeeze of lemon juice for acidity, which can brighten the overall flavor profile of the soup.
Roasting Cauliflower
Roast cauliflower until caramelized to enhance its flavor. Toss with oil and seasoning, and break into smaller pieces for extra browning towards the end of roasting. This adds texture to the soup when used as a topping.
Infused Oil Usage
A drizzle of infused oil, such as spicy chili oil, adds depth and complexity to the dish. Add it just before serving to preserve its flavor and aromatic qualities.
