Keto Butternut Squash Soup Recipe
This recipe keeps the essence of traditional butternut squash soup, but swaps out any high-carb ingredients for keto-friendly alternatives. You’ll end up with a rich, creamy bowl of comfort that’ll keep you warm and satisfied without derailing your diet.
Here’s how to make it:
Ingredients Needed
To make the most delicious Keto Butternut Squash Soup, you’ll need the following ingredients:
- 1 medium butternut squash (peeled and diced)
- 1 tablespoon olive oil (for roasting the squash)
- 1 medium onion (diced)
- 2 cloves garlic (minced)
- 4 cups low-sodium vegetable broth (or chicken broth for a richer flavor)
- 1/2 cup heavy cream (for that creamy texture, you can substitute with coconut cream if dairy-free)
- 1 teaspoon ground ginger (for a slight kick)
- 1/2 teaspoon ground turmeric (for depth and color)
- 1/4 teaspoon ground cinnamon (a pinch for warmth)
- 1/4 teaspoon ground nutmeg (for a subtle spice)
- Salt and pepper (to taste)
- Fresh thyme or parsley (for garnish)
Cooking Instructions
Step 1: Roast The Squash
- Preheat your oven to 400°F (200°C).
- Peel and dice the butternut squash into 1-inch cubes. Toss the cubes in olive oil, and season with a pinch of salt and pepper.
- Spread the squash evenly on a baking sheet and roast in the preheated oven for 25-30 minutes, or until the squash is tender and lightly caramelized.
- The roasting process enhances the natural sweetness of the squash, so don’t skip this step!
Step 2: Sauté The Aromatics
- In a large pot, heat olive oil over medium heat.
- Add the onions and sauté until soft and translucent, about 5-7 minutes.
- Add the garlic and sauté for another minute until fragrant.
Step 3: Simmer The Soup
- Add the roasted butternut squash to the pot with the onions and garlic.
- Pour in the vegetable broth and bring it to a boil. Once it’s boiling, reduce the heat and let it simmer for about 10-15 minutes, allowing the flavors to meld together.
Step 4: Blend Until Smooth
- Once the squash is soft and the broth has absorbed all the delicious flavors, use an immersion blender to puree the soup directly in the pot. If you don’t have an immersion blender, you can carefully transfer the soup in batches to a regular blender, then return it to the pot once blended.
- Blend until the soup is completely smooth and creamy.
Step 5: Finish The Soup
- Stir in the heavy cream and the spices: ginger, turmeric, cinnamon, and nutmeg.
- Season with salt and pepper to taste.
- Heat through for a few more minutes, then serve hot, garnished with fresh thyme or parsley.
Ingredient Insights
Let’s break down the key ingredients in this recipe and their nutritional benefits:
- Butternut Squash: This vegetable is naturally high in fiber and packed with vitamins A and C, but it can be a bit high in carbs. In keto cooking, you’ll find that a moderate portion is still manageable when balanced with other low-carb ingredients.
- Heavy Cream: A rich and creamy addition that provides a luxurious texture without the carbs. It adds fat, which is essential for a keto diet, helping keep you satiated and supporting energy levels.
- Turmeric & Ginger: Both of these spices offer significant anti-inflammatory properties. Plus, they give the soup that comforting, warm depth of flavor. Turmeric is also known to support digestion and immune health, while ginger adds a little zing.
- Cinnamon & Nutmeg: These spices bring a subtle, warming touch. They’re not just for desserts! They’re fantastic at balancing out the sweetness of the squash and adding layers to the flavor profile.
- Low-Sodium Broth: Using a low-sodium broth helps control the salt levels and keeps the soup from becoming too salty, which could overpower the natural sweetness of the squash.
Expert Tips
- Roast the Squash First: Roasting the squash intensifies its sweetness and flavor. It also allows the squash to caramelize, adding a richer, deeper taste that blending it raw would not give you.
- Use Full-Fat Ingredients: For a truly creamy texture, opt for full-fat heavy cream instead of half-and-half or milk. The richness will keep the soup satisfying and help you meet your fat macros for the keto diet.
- Control the Thickness: If the soup is too thick for your liking, add a little extra broth or water until you reach your desired consistency. A thicker soup is perfect for those colder months, but feel free to adjust based on your preference.
- Make Ahead & Store: This soup keeps beautifully in the fridge for about 3-4 days. You can even freeze it for up to 3 months. Just make sure to cool it completely before transferring it to an airtight container for storage.
Recipe Variations
While this recipe is fantastic as-is, sometimes it’s fun to mix things up! Here are some easy variations you can try:
- Add Protein: For a heartier version, add shredded chicken or ground turkey to the soup. It’s an excellent way to make this a complete meal.
- Coconut Milk: If you prefer a more tropical twist or are following a dairy-free keto diet, swap the heavy cream for coconut milk. This will give the soup an extra layer of richness.
- Spice it Up: If you like a bit of heat, add some cayenne pepper or finely chopped jalapeños. The heat works well with the sweetness of the squash.
- Top it Off: Try topping the soup with a dollop of sour cream or crème fraîche for extra creaminess. Or, sprinkle some bacon bits or roasted pumpkin seeds for added crunch.

FAQs
What Makes Butternut Squash Soup Keto-friendly?
Butternut squash soup is considered keto-friendly when prepared with low-carb ingredients, such as avoiding high-carb additives like potatoes and sugars. The key to keeping it keto is using minimal amounts of butternut squash (as it contains carbs), opting for low-carb alternatives like heavy cream or coconut milk for creaminess, and avoiding high-carb thickeners like flour.
Can I Use Other Squashes For Keto Butternut Squash Soup?
While butternut squash is commonly used in keto soups due to its natural sweetness and texture, other squashes like acorn or spaghetti squash can also be used in moderation. However, they may alter the flavor and texture slightly, so it’s important to balance the portion sizes to stay within the desired carb count.
How Do I Lower The Carb Content In A Keto Butternut Squash Soup Recipe?
To lower the carb content, you can reduce the amount of butternut squash, or combine it with lower-carb vegetables such as cauliflower or zucchini. Additionally, replace any starchy thickeners like potatoes or flour with keto-friendly options like almond flour, coconut flour, or xanthan gum.
What Ingredients Should I Avoid In A Keto Butternut Squash Soup Recipe?
Avoid ingredients that are high in carbs, such as potatoes, carrots, corn, or any form of sugar. Additionally, steer clear of high-carb stock cubes that may contain sugar or starches, as well as dairy-based ingredients like milk or half-and-half, which can add unnecessary carbs.
Can I Use Vegetable Broth Instead Of Chicken Broth For This Recipe?

How Can I Add More Flavor To Keto Butternut Squash Soup?

How Do I Thicken Keto Butternut Squash Soup Without Using Flour?
