Creamy Low FODMAP Pumpkin Soup (Dairy Free & Gluten Free)

This creamy Low FODMAP Pumpkin Soup is the recipe I brought to a bachelorette party for a bride with celiac, and more than one guest pulled me aside to ask for it before the night was over. In my world, that's basically winning an Oscar. Roasting the kabocha squash, sweet potatoes, and carrots first is what builds the flavor, then the slow cooker lets everything meld together into a velvety, dairy free soup that tastes like it took way more effort than it did.

I am a big believer that pumpkin and coconut belong together, and this soup is proof. Coconut milk is what gives it that creamy finish without any dairy, and if that combo speaks to you, my low FODMAP pumpkin bread made with dairy free coconut yogurt is worth a look next.

Roast the vegetables the night before, toss everything in the slow cooker in the morning, and by dinner it's done. One pot, zero flavor sacrifices, and nobody at the table has to eat a different version. That counts as a win.

Why You'll Love This Recipe

• A thick, creamy bowl with zero dairy and zero gut drama
• Big fall flavor from a spice blend that does all the heavy lifting
• Naturally gluten free, dairy free, and low FODMAP
• The slow cooker does most of the work
• Makes a large batch that freezes beautifully for later
• Works for a weeknight dinner or a holiday starter

What You'll Need

• Kabocha Squash - This is the star. Kabocha has a naturally sweet, dense flesh that roasts up beautifully and gives the soup its body. If you cannot find it, canned pumpkin puree is a great swap and saves a step.
• Carrots + Sweet Potatoes - These two vegetables add natural sweetness and a beautiful orange color. Roasting them alongside the squash brings out flavors that simmering alone just cannot match.
• Garlic-Infused Olive Oil - All the savory garlic depth without any of the FODMAPs. This is the workaround that makes low FODMAP cooking actually taste good. If garlic is tolerated in your house, go ahead and roast a couple of smashed cloves right alongside the sweet potatoes.
• Spice Blend - Ground cinnamon, pumpkin pie spice, ginger, coriander, turmeric, and cumin. It sounds like a lot, but this is what makes the soup taste complex and cozy instead of flat. Worth every jar you pull out of the cabinet.
• Canned Coconut Milk - This is what makes this dairy free pumpkin soup so rich and creamy. Use unsweetened, full-fat canned coconut milk for the best result.
• Unsweetened Almond Milk - Lightens things up a little and helps bring the soup to the right consistency. Lactose-free milk works here too.
• Vegetable Broth - Use a low FODMAP-friendly option or one you know you tolerate well. This gives the soup its base and can be adjusted for thickness. A good broth makes a real difference here, the same way it does in my Low FODMAP Chicken Noodle Soup.
• Bay Leaf - Low and slow cooking with a bay leaf adds a subtle depth. Just remember to fish it out before blending!

Step-By-Step Instructions

Step 1: Preheat the oven to 400 degrees F. Carefully slice the kabocha squash in half on a sturdy cutting board. Remove the stem and scrape out the seeds with a spoon. Place the squash cut-side up on a parchment-lined baking sheet. Drizzle with garlic-infused olive oil and sprinkle with salt and pepper. Roast for 45-60 minutes, or until fork tender.

Step 2: While the squash roasts, peel and dice the carrots and sweet potatoes into similar-sized pieces. Place on a separate parchment-lined baking sheet, drizzle with garlic-infused olive oil, and season with salt and pepper. Roast for 30 minutes.

The roasting is the step that makes this gluten free pumpkin soup taste like something from a restaurant. Do not skip it.

Step 3: Once the roasted vegetables are done, let them cool slightly. Scoop the kabocha squash flesh away from the skin and add it to a 6-quart slow cooker along with the roasted carrots and sweet potatoes.

Step 4: Add 3 cups of vegetable broth, all of the spices, and the bay leaf to the slow cooker. Stir to combine. Set the slow cooker to low for 6-8 hours or high for 3-4 hours.

Step 5: Remove the bay leaf. Use an immersion blender to puree the soup directly in the slow cooker until smooth and creamy. Work carefully because the soup is very hot. No immersion blender? Transfer the soup in batches to a regular blender and blend until smooth.

Step 6: Stir in the canned coconut milk and almond milk. Taste and adjust the salt and pepper. If the soup is thicker than you like, add additional vegetable broth a little at a time until you hit the consistency you want.

Ladle into bowls and add your favorite toppings. Serve immediately.

Meal Prep This Recipe

This is a great soup to break into two days so it does not feel like a big project on a weeknight. Here is how to make it work.

Sunday: Roast the vegetables. Roast the kabocha squash, sweet potatoes, and carrots all at once. Both pans can go into the oven at the same time since they roast at the same temperature. Once everything is done and cooled, scoop the squash flesh away from the skin. Store the squash, carrots, and sweet potatoes together in an airtight container in the refrigerator for up to 3 days.

Weekday: Finish the soup. Add the cold roasted vegetables straight to the slow cooker with the broth and spices. No reheating needed first. Set it in the morning on low, and by dinnertime the soup is ready to blend. The whole active time on the day you serve it is maybe 10 minutes.

This is the same approach I use for my Low FODMAP Sweet Potato Mash when I need a fast side dish during the week. Roast ahead, reheat fast, dinner done.

Want to go even further? Make the full soup on Sunday and refrigerate or freeze it in portions. It reheats beautifully and the flavor is honestly better the next day. One Sunday cooking session, multiple easy meals. My kind of math.

Ingredient Swaps

• Kabocha Squash - Use 3 cups of canned pumpkin puree as a 1:1 swap. No roasting needed for the squash. Add it straight to the slow cooker.
• Almond Milk - Lactose-free milk, regular milk, or additional coconut milk all work here. Use whatever your gut tolerates best.
• Vegetable Broth - Low FODMAP chicken broth works as a swap if that is what you have on hand.

Variations

Roasted Pumpkin Soup: Use a sugar pumpkin or pie pumpkin in place of kabocha squash. Halve it, roast it the same way, and scoop out the flesh. The flavor is slightly different but equally cozy.

Spicier Pumpkin Soup: Add a pinch of cayenne pepper to the spice blend. It adds warmth without overwhelming the fall flavors. My teens would vote yes every time.

Stovetop Version: Skip the slow cooker. After roasting the vegetables, add everything to a large pot and simmer on medium-low for 30 minutes. Blend and finish with the coconut milk as directed.

Soup Toppings

One of the best parts about this soup is how easy it is to dress up. A few favorites:

• Swirl of canned coconut milk or coconut cream
• Toasted pumpkin seeds (pepitas)
• A pinch of smoked paprika or cinnamon
• Chopped fresh parsley or chives
• Gluten free crackers for dipping
• A drizzle of garlic-infused olive oil

Storing and Reheating

Store: Keep leftover soup in an airtight container in the refrigerator for up to 4 days. The flavor gets better the next day, which is always a good sign.

Reheat: Warm on the stovetop over medium-low heat, stirring occasionally. Add a splash of vegetable broth or almond milk if the soup has thickened in the fridge. The microwave works too. Heat in 60-second intervals and stir between each one.

Freeze: This soup freezes really well. Let it cool completely, then transfer to freezer-friendly containers or zip-top bags. Freeze for up to 4 months. Thaw overnight in the refrigerator before reheating. Add a splash of broth when warming to bring the consistency back.

Low FODMAP Notes

Low FODMAP ingredient information is based on the Monash University Food App and FODMAP Friendly App testing results as of the day posted. As always, modify based on your gut and what works for you on a low FODMAP diet.

• Kabocha Squash/Japanese Pumpkin/Kent Pumpkin - Safe at ⅓ cup or 75 grams per meal. 
• Sweet Potatoes - Safe at ½ cup or 75 grams per meal. 
• Carrots - Safe at 1 small or 75 grams per meal. 
• Garlic Infused Olive Oil - Garlic are water-soluble, not oil-soluble, which means all the garlic flavor transfers into the oil but the FODMAPs stay behind with the garlic pieces. This is why it shows up in almost every savory recipe on this site. My Low FODMAP Lemon Parmesan Chicken uses the same trick if you want another great weeknight option.
• Vegetable Broth - Use a low FODMAP option without onion or garlic. 
• Spices
  • Ground Ginger - Dried ginger has not been tested, but fresh ginger has been tested safe at 1 teaspoon or 5 grams per meal. 
  • Ground Coriander - Safe at 1 teaspoon or 2 grams per meal. 
  • Turmeric - Safe at 1 teaspoon or 2 grams per meal. 
  • Cumin - Safe at 1 teaspoon or 2 grams per meal. 
  • Bay Leaf - Safe at 1 leaf or 1 gram per meal. 
• Unsweetened Almond Milk - Safe at 1 cup or 240 grams per meal. 
• Full-Fat Coconut Milk - Safe at ¼ cup or 60 grams per meal.

FAQs

What To Serve With Pumpkin Soup

This soup is hearty enough on its own but really shines with something on the side. A warm slice of Low FODMAP Cornbread is the move if you want something to scoop and dip alongside the bowl.

For a bigger meal, Low FODMAP Flaky Tender Biscuits alongside this soup make a cozy dinner that feels way more put-together than the effort involved.

Serving this as a starter for a holiday meal? It fits right in. My Slow Cooker Boneless Turkey Breast and this soup together make a Thanksgiving spread that nobody walks away from hungry.
