Step-by-Step Instructions

Step 1: Prepare Your Vegetables
Preheat your oven to 425°F (220°C). On a large baking sheet, spread out your pumpkin cubes, cauliflower florets, quartered onions, and garlic cloves. Drizzle with olive oil, sprinkle with half the thyme, season with salt and pepper, and toss until evenly coated. For a perfectly roasted vegetable base, ensure your pieces are similar in size for even cooking.
Step 2: Roast the Vegetables
Place the baking sheet in the preheated oven and roast for 25-30 minutes, stirring halfway through, until the vegetables are tender and caramelized at the edges. The roasting process is crucial for this Roasted Pumpkin & Cauliflower Soup, as it develops deep, complex flavors that make this recipe stand out from ordinary soups.
Step 3: Simmer the Soup
Transfer the roasted vegetables to a large pot. Add the broth, remaining thyme, and cumin. Bring to a simmer over medium heat and cook for 10 minutes to allow the flavors to meld. The combination of herbs and spices will elevate your Roasted Pumpkin & Cauliflower Soup from good to extraordinary.
Step 4: Blend Until Smooth
Using an immersion blender, puree the soup until velvety smooth. If you don’t have an immersion blender, carefully transfer the mixture in batches to a standard blender, then return to the pot. Remember to vent the blender lid to allow steam to escape.
Step 5: Add Final Touches
Stir in the coconut milk or cream and maple syrup (if using). Simmer for another 5 minutes. Taste and adjust seasonings as needed. Your Roasted Pumpkin & Cauliflower Soup should have a perfect balance of sweet, savory, and earthy notes.
