Smooth, delicious, cozy roasted pumpkin and cauliflower soup. Our dairy-free pumpkin soup still gives that sought-after creamy texture without the need for cream or coconut milk. We swapped those for potatoes and roasted garlic to maximize flavor and texture!

Honestly, I find coconut cream or milk too sweet and rich for pumpkin soup, which is what many other dairy-free recipes use. Potatoes, with their mild flavor and creamy texture, is the perfect alternative. Along with roasted garlic, they give this soup an extra kick of flavor and smoothness without being overly rich or heavily spiced.

I love finding creative and unique ways to make recipes allergy-friendly while still nutritious, easy, and of course delicious. Like our roasted carrots and asparagus with a hummus-dill dressing, or instant-pot zucchini broccoli soup (ready in 10 minutes)!

  • Has A Great Texture: This hearty soup has a creamy texture and sweet flavor appeal to most children.
  • Add Cripsy Croutons: Serving it with fun, colorful toppings, croutons, or crusty bread for dipping.
  • Include Your Kid: Involving kids in the preparation process. Not only is this a great time to spend together but it also helps get them excited about the meal. Let them decide how much spice to add or how creamy to make it.

🧠Nutrient Highlight: Why Eat This?

If you've been following along for a bit, you'll know my passion for health, neuroscience, and nutrition—shoutout to my Ph.D.—fuels my desire to create recipes that balance taste and nutrition. Here is how this roasted pumpkin and cauliflower soup shakes out:

  • Rich in Vitamin A: Vitamin A is a powerhouse for the brain. It supports brain function, healthy vision, and the immune system (1, 2, 3).
  • Filled with Antioxidants (Vitamin C): Shields the brain from oxidative stress and aids in neurotransmitter synthesis (4).
  • Contains Fiber: Promotes gut health, which is directly linked to cognitive health and emotional well-being (5, 6).

🍲Main Ingredients

Here are the main healthy ingredients you need for our creamy pumpkin and cauliflower soup:

A neatly organized selection of soup ingredients: bowls of chopped cauliflower, yellow potatoes, bright orange pumpkin pieces, and a dish of fresh garlic with labels, on a marble countertop.
  • Medium Pumpkin: I chose pumpkin for its sweet, earthy flavors and creamy texture making our soup rich.
  • Cauliflower Florets: I include it for its ability to blend into a smooth consistency, enhancing the soup's body without overpowering the pumpkin's flavor.
  • White Potato (optional): I add potato in place of any cream to help achieve an even creamier texture.
  • White Onion and Garlic Cloves: Onions and garlic are a great base for most recipes, especially soups.
  • Vegetable Broth: Adding vegetable stock instead of water adds even more flavor and depth to this cauliflower pumpkin soup.
  • Olive Oil: We will be adding this over our veggies to help them caramelize while roasting.
  • Ground Cumin and Smoked Paprika: These spices introduce a subtle warmth and smokiness.
  • Italian seasoning: Adds a light, herbal freshness that balances the richer flavors.
  • Salt and Black Pepper: Basic but essential, they fine-tune the taste to perfection.

For full quantities, see the recipe card.

👩🏽‍🍳How to Make Pumpkin Cauliflower Soup

Step 1: Preheat Oven And Prep Veggies

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Then, break the cauliflower into florets, and roughly chop the pumpkin and potato into 1-inch cubes (or small chunks). Dice the onion into quarters and remove the skin form the garlic cloves.

Chopping Tip: Don't worry too much about this step, you want the veggies to all be roughly the same size but it doesn't have to be perfect.

Step 2: Season The Veggies

Spread all your prepped veggies on the baking sheet. Drizzle with 2 tablespoons of olive oil, and sprinkle with the paprika, cumin, Italian seasoning, salt, and pepper. Give them a good toss to ensure they're well-coated.

Step 3: Roast the Pumpkin Cauliflower Mix

Roast them for about 25-30 minutes. Halfway through stir the roast vegetables for an even caramelization.

Step 4: Blend Roasted Veggies

Once roasted, it’s time to blend. Carefully transfer the roasted pumpkin cauliflower soup mixture into a high-speed blender, adding 4 cups of vegetable broth. Blend until smooth.

Step 5: Taste and Adjust

Blend your soup until you get the consistency you prefer. For a creamy version let the soup blend for a few minutes. Then carefully taste the roasted pumpkin cauliflower soup and adjust if you feel like it needs more spice or salt.

Step 6: Serve and Enjoy

Pour the creamy pumpkin soup into bowls. If you want to go an extra step, garnish each soup bowl with pumpkin seeds, a dollop of vegan Greek yogurt, coconut cream, or sour cream and a sprinkle with some fresh herbs.

💡Recipe & Time-Saving Tips

I make this creamy vegan soup often for my family, so let me share some of the things that have helped me:

  1. Use Pre-Cut Pumpkin: I find it helpful to buy a bag of frozen cubed pumpkin (especially when it is not pumpkin season) or pre-chopped fresh pumpkin from the grocery store.
  2. Batch Cook: Pumpkin and cauliflower soup is a great recipe to batch-make and freeze. It reheats well for a light dinner or fast recipe on a busy day.
  3. Make Ahead: Soup often tastes better the next day so don't be afraid to make this recipe ahead of time.
  4. Add Fresh Herbs: Adding fresh herbs (like parsley, thyme, or dill) can boost the soup's flavor.
  5. Get a Creamy Blend: Use a high-speed blender to get your soup nice and creamy.
  6. Add Lemon: Adding a squeeze of lemon juice to each bowl will help bring out the flavor and balance out the creaminess of this soup.
  7. Taste and Adjust: Be sure to taste your soup after blending to adjust the spices before serving.

🥬Substitutions

It sucks when we want to make a recipe but then realize we are missing an ingredient (been there!). So here are some suggestions for substitutions in case you're missing an ingredient for this roasted cauliflower pumpkin soup:

  • Pumpkin: If fresh pumpkin isn't available, canned pumpkin purée is a great alternative, especially outside of pumpkin season. Just be sure it's pure pumpkin, not pumpkin pie filling.
  • Cauliflower: Broccoli can serve as a good substitute for cauliflower, offering a similar texture and nutritional profile. Or check out our broccoli zucchini soup recipe!
  • Vegetable Broth: Chicken broth (for non-vegans) or water with a bit more seasoning can be used if you're out of vegetable broth.
  • Olive Oil: Any neutral oil, like avocado or canola, can be used for roasting vegetables.
  • Spices: Other spices that work well in this soup are nutmeg, ginger, oregano, or dried thyme.

🍽️Leftover and Variations Ideas

  • Spice it Up: Add a bit of heat with a dash of red pepper flakes or a spoonful of chili paste.
  • Roast Vegetable Addition: Mix in other vegetables like sweet potatoes or parsnips for a different taste and texture.
  • Make it Protein-Rich: Stir in some cooked quinoa or beans for added protein and heartiness.

🥡Storage

Fridge: Store any leftover roasted pumpkin cauliflower soup in an airtight container in the fridge for up to 4 days.

Freezer: Pour your cauliflower pumpkin soup into freezer-safe bags or containers, leaving some space for expansion. It's best used within 3 months. Thaw overnight in the fridge before reheating.

Reheating: When reheating your cauliflower pumpkin soup recipe, you might need to add a little extra broth or water, as the soup can thicken when stored. Warm it on the stove over low heat until it reaches serving temperature.

❔Recipe FAQ

Can I make pumpkin cauliflower soup without a blender?

Yes, if you don't have a blender, you can use a potato masher for a chunkier texture. Alternatively, you can use an immersion blender if you have one.

Why is my pumpkin cauliflower soup so bland?

If you find your dairy-free pumpkin soup to be bland, add a bit more salt, and spices (cumin and paprika). We also recommend adding a squeeze of lemon to elevate the flavors.

What if my soup is too thick?

If your cauliflower pumpkin soup turns out thicker than you prefer, gradually stir in more vegetable broth until you reach the desired consistency.
