Why You’ll Love Sheet Pan Roasted Pumpkin Cauliflower Soup Recipe
This soup is easy to make, packed with roasted vegetable flavor, and perfect for chilly days when you want something nourishing and satisfying. Roasting the pumpkin, cauliflower, potatoes, onion, and garlic brings out their natural sweetness and creates a deeper, more savory taste than a stovetop-only soup. It is also naturally dairy-free, easy to customize, and beautiful enough to serve for a casual dinner or holiday starter. Since the vegetables roast together on a sheet pan, cleanup is simple and the hands-on time is minimal.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 medium pumpkin, peeled and cubed (about 4 cups)
1 small cauliflower, broken into florets
2 white potatoes, peeled and cubed
1 onion, quartered
4 garlic cloves, peeled
4 cups vegetable broth
2 tbsp olive oil
2 tbsp smoked paprika
2 tbsp Italian seasoning
1 tbsp ground cumin
1 tsp salt
1/4 tsp pepper
lemon
fresh herbs
vegan plain yogurt
croutons (gluten-free)
Directions
Begin by preheating your oven to 400°F (200°C) and lining a baking sheet with parchment paper.
Cut the cauliflower into florets. Peel and cube the pumpkin, cube the potatoes, quarter the onion, and peel the garlic cloves.
Place all the prepared vegetables on the baking sheet. Drizzle with olive oil, then season with smoked paprika, Italian seasoning, cumin, salt, and pepper. Toss well so everything is evenly coated.
Roast for 25 to 30 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized around the edges.
Carefully transfer the roasted vegetables to a high-speed blender and pour in the vegetable broth. Blend until smooth and creamy, allowing steam to escape and working in batches if needed.
For an immersion blender method, add the roasted vegetables and broth to a large pot, then blend until the soup reaches a smooth, velvety consistency.
Taste and adjust the seasoning if needed. Ladle the soup into bowls and finish with a squeeze of lemon, fresh herbs, vegan yogurt, and croutons for garnish.
Servings and timing
This recipe makes 6 servings and takes about 45 minutes from start to finish.
Prep time is about 15 minutes, while the roasting and blending take around 30 minutes total.
Variations
For a slightly sweeter soup, add a few chunks of roasted carrot or sweet potato to the pan before roasting. If you want extra heat, stir in a pinch of cayenne pepper or red pepper flakes before blending. For an even richer texture, add a splash of canned coconut milk or extra vegan yogurt at the end.
You can also swap the pumpkin for butternut squash if that is easier to find. To make the soup even heartier, top it with roasted chickpeas or serve it with crusty bread on the side. Fresh thyme, parsley, or sage all work well as herb garnishes, depending on the flavor you want.
Storage/Reheating
Store leftover soup in an airtight container in the refrigerator for up to 4 days. The flavor often becomes even better after a day, making it great for meal prep.
To reheat, warm the soup gently in a saucepan over medium-low heat, stirring occasionally until heated through. You can also microwave individual portions in short intervals, stirring between each one. If the soup thickens too much after chilling, add a splash of vegetable broth or water to loosen it.
This soup also freezes well. Let it cool completely, then transfer it to freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
