Roasted Butternut Squash Soup

Fall does not officially begin when the calendar says so. It begins when a tray of squash starts caramelizing in the oven and the whole kitchen smells like maple, ginger, and toasted edges.

To keep this Roasted Butternut Squash Soup Low-FODMAP-friendly, butternut shares the pan with kabocha and carrots, while garlic-infused oil and scallion green tops build savory depth without onion or garlic cloves. A carefully chosen broth keeps the finished soup gluten-free and lactose-free too.

Once blended, every spoonful is smooth, lightly sweet, and warm with nutmeg. Make it for the first cool evening of fall, then tuck a few portions into the freezer for the nights when a bowl of something golden sounds exactly right.

Ingredients

Materials Needed

• Large rimmed baking sheet
• Parchment paper, optional
• Cutting board and sharp chef's knife
• Vegetable peeler and sturdy spoon
• Measuring cups and measuring spoons
• Large soup pot
• High-powered blender or immersion blender
• Ladle
• Small bowl for the yogurt garnish, optional

Step-by-Step Instructions

1. 1

   Heat the oven

   Preheat the oven to 425°F. Line a large rimmed baking sheet with parchment paper if you want easier cleanup.

2. 2

   Prep the vegetables

   Cut the butternut squash, kabocha, and carrots into similar 1-inch pieces. Keeping the cubes close in size helps everything roast at the same pace.

3. 3

   Season the sheet pan

   Add the squash and carrots to the baking sheet. Drizzle with 2 tablespoons garlic-infused olive oil, then season with salt and black pepper and toss well.

4. 4

   Roast until caramelized

   Roast for 30 minutes, then stir the vegetables and add the scallion green tops. Roast for 10 to 15 minutes more, until the squash is tender and browned around the edges.

5. 5

   Build the soup

   Transfer the roasted vegetables to a large pot. Add the broth, maple syrup, ginger, nutmeg, cinnamon, lemon juice, and the remaining tablespoon of garlic-infused olive oil.

6. 6

   Warm gently

   Bring the soup to a gentle simmer over medium heat and cook for 5 minutes. Remove the pot from the heat and let it stand for a few minutes before blending.

7. 7

   Blend until silky

   Use an immersion blender in the pot, or carefully blend the soup in batches with the lid vented. Blend until smooth, then add a splash of broth if you prefer a thinner consistency.

8. 8

   Taste and serve

   Season with additional salt, pepper, or lemon juice as needed. Ladle about 3/4 cup into each bowl and finish with pepitas, herbs, or a small swirl of lactose-free yogurt.

Low-FODMAP Notes

Butternut squash can become higher in FODMAPs as the serving grows, so this recipe uses a measured amount and divides the soup into 12 small bowls. Kabocha and carrots keep the soup full and squash-forward without relying on a large portion of butternut in each serving.

Garlic-infused olive oil and scallion green tops replace garlic cloves and bulb onion. Choose a broth that is certified gluten-free and free from onion, garlic, wheat, inulin, chicory root, and other ingredients that may not fit your routine.

This recipe is designed with Low-FODMAP-friendly ingredients, but it has not been lab-tested. Individual tolerance and serving needs vary, so use current label information and personalized guidance when needed.

Recipe Tips

• Let the edges get deep golden. Those browned corners give the blended soup a richer roasted flavor.
• Blend hot soup carefully. Work in batches, vent the blender lid, and cover the opening loosely with a folded kitchen towel.
• Keep portions consistent. Dividing the pot into 12 small bowls helps keep the butternut squash amount conservative.
• Freeze before garnishing. Cool the soup completely, freeze it in individual containers, and add yogurt or pepitas after reheating.
