Creamy Keto Pumpkin Soup: Low-Carb Fall Comfort Recipe

A comforting keto pumpkin soup that’s creamy, flavorful and ideal for chilly days. Gluten-free, sugar-free, and quick to make.

Easy keto pumpkin soup recipe

A warm bowl of soup feels especially good when the temperature drops. This easy keto pumpkin soup is one of my favorites when pumpkins are in season. It’s creamy, spiced just right, and far from boring.

The recipe is versatile — you can tweak spices, add proteins or swap dairy for coconut to suit your preferences. Using canned pumpkin puree keeps this soup quick: it comes together in about 20 minutes.

Is pumpkin keto friendly?

Yes — pumpkin is keto friendly in moderation. It’s rich in vitamins like A, C and E and contains useful fiber. A half-cup of cooked pumpkin has roughly 6 grams of total carbs and about 4.5–5 grams of net carbs, so it can fit into a keto meal plan when portions are controlled.

Ingredients

Simple pantry staples are all you need:

• Canned pumpkin – use pure pumpkin puree. For fresh pumpkin see the section below.
• Chicken broth/stock – or use a bouillon cube for flavor.
• Heavy cream – substitute coconut cream for a dairy-free version.
• Onion – half a small onion, chopped; onion powder can be used if you prefer.
• Garlic – 2–3 cloves, minced.
• Butter – for sautéing; avocado, coconut or olive oil also work.

How to use fresh pumpkin for the soup

If you prefer fresh pumpkin, choose small baking varieties such as sugar or pie pumpkins rather than large carving pumpkins. Cut the pumpkin in half, remove seeds and strings, brush the flesh with oil and roast at 375°F (190°C) for about 40 minutes or until tender. Cool, scoop out the flesh and mash or puree it.

Reserve or roast the seeds (pepitas) for a crunchy garnish. You’ll need about the same volume of fresh pumpkin puree as canned — roughly 15 oz (about 1 3/4 cups).

How to make

Start by melting butter in a pot and sautéing the chopped onion and minced garlic until the onion softens and becomes translucent.

Add the pumpkin puree, chicken stock, salt, black pepper, a pinch of cayenne and nutmeg. Stir to combine and bring to a boil, then reduce heat and simmer for about 10 minutes to let the flavors meld.

Remove the pot from the heat and use an immersion blender to puree the soup until smooth. Return to the stove, stir in heavy cream and warm through gently. Taste and adjust seasoning as needed.

Serve topped with pepitas, a swirl of cream or sour cream, and low-carb croutons if desired.

To make low-carb croutons: cut low-carb bread into cubes, toss with a little oil and salt, then air-fry at 350°F (175°C) for about 5 minutes or bake until crisp.

Variations on keto pumpkin soup

Change the profile of the soup by adding different flavors and ingredients. A few ideas:

• Keto Thai pumpkin soup with coconut milk – sauté onion and garlic, add 1 tablespoon red curry paste, then stir in pumpkin puree, 1 cup coconut milk and 2½ cups chicken stock. Add a pinch of low-carb sweetener if desired, simmer, then blend until smooth.
• Keto pumpkin soup with bacon – fry 1–2 strips of bacon until crisp. Remove and use the bacon fat to sauté onion and garlic, then continue with the recipe. Crumble bacon over each bowl before serving.
• Curried keto pumpkin soup – sauté onion, garlic and 1 teaspoon minced ginger. Add 1 teaspoon cumin, 1 teaspoon coriander, 1/2 teaspoon turmeric and 1/4 teaspoon chili powder; cook briefly to bloom the spices. Continue with the base recipe and finish with a pinch of garam masala before serving.

Storing keto pumpkin soup

Refrigerate leftovers for 4–5 days. The soup freezes well for up to 3 months. Because creamy soups can separate after freezing, consider freezing the soup without the cream and add the cream after thawing when you reheat it.
