A comforting keto pumpkin soup that’s creamy, delicious, and perfect for chilly days. Gluten-free, sugar-free, and simple to make.

Easy keto pumpkin soup recipe

When the weather cools down, a warm bowl of soup is my go-to comfort food. This easy keto pumpkin soup is one of my favorites during pumpkin season. It’s creamy with a gentle spice warmth and far from the same old pumpkin soup.

This recipe is versatile — you can adjust spices and add-ins to suit your tastes — and it’s quick to prepare. Using canned pumpkin puree keeps things simple and lets you have the soup ready in under 20 minutes.

Is pumpkin keto friendly?

Yes — pumpkin can fit into a keto diet when eaten in moderation. Pumpkin is rich in vitamins such as A, C and E, and contains useful fiber. A half-cup serving of pumpkin puree provides a modest amount of carbs: roughly 6 grams total, which is about 4.5–5 grams net carbs depending on the brand. That makes pumpkin manageable within a low-carb meal plan.

Ingredients

Only a handful of pantry staples are needed:

• Canned pumpkin – use pure pumpkin puree. See the section below for how to use fresh pumpkin if you prefer.
• Chicken broth/stock – provides the base flavor. A bouillon cube dissolved in water works too.
• Heavy cream – swap in coconut cream for a dairy-free version.
• Onion – half of a small onion, chopped. You can use onion powder, but sautéed onion adds great depth.
• Garlic – 2–3 cloves, minced.
• Butter – for sautéing the aromatics. Avocado oil, coconut oil, or light olive oil are good alternatives.

How to use fresh pumpkin

If you want to make your own pumpkin puree, choose small baking pumpkins often labeled “sugar pumpkins” or “pie pumpkins.” Avoid large carving pumpkins, which are best for decoration.

Cut the pumpkin in half, remove seeds and fibers, brush the flesh with oil, and roast at 375°F (190°C) for about 40 minutes or until fork-tender. Let cool, scoop out the flesh, and mash or blend until smooth. Reserve roasted pepitas (pumpkin seeds) for garnish if you like. You’ll need about 15 oz (1 3/4 cups) of fresh pumpkin puree to match a 15 oz can.

How to make

Heat butter in a pot over medium heat. Add chopped onion and minced garlic, sautéing until the onions begin to sweat. Stir in the pumpkin puree, chicken stock, salt, black pepper, a pinch of cayenne, and nutmeg. Bring to a gentle boil, then reduce heat and simmer for about 10 minutes to let the flavors meld.

Remove the pot from the heat and blend the soup until smooth using an immersion (stick) blender. Alternatively, let it cool slightly and puree in a countertop blender in batches. Return to the stove, stir in the heavy cream, and warm through. Adjust seasoning if needed.

Serve topped with pepitas or pumpkin seeds and a drizzle of cream or a dollop of sour cream. Low-carb croutons are a great crunchy addition: cube low-carb bread, toss with oil and salt, then air-fry at 350°F (175°C) for about 5 minutes or bake until crisp.

Variations on keto pumpkin soup

Here are a few flavorful ways to change up the base recipe:

• Keto Thai pumpkin soup with coconut milk – Sauté onions and garlic, add 1 tablespoon red curry paste and cook briefly. Add pumpkin puree, 1 cup coconut milk, and 2 1/2 cups chicken stock. Add a pinch of sweetener if desired. Simmer 10 minutes and blend until smooth.
• Keto pumpkin soup with bacon – Fry 1–2 strips of bacon until crispy. Remove bacon, sauté onions and garlic in the bacon fat, then continue with the recipe. Crumble the bacon over the finished soup.
• Curried keto pumpkin soup – Sauté onion, then add garlic and 1 teaspoon minced ginger. Stir in 1 teaspoon cumin, 1 teaspoon coriander, 1/2 teaspoon turmeric, and 1/4 teaspoon red chili powder. Toast the spices briefly without burning, then add pumpkin and broth. Finish with a pinch of garam masala before serving.

Storing keto pumpkin soup

Store the soup in the refrigerator for 4–5 days or freeze for up to 3 months. If freezing, omit the cream before freezing; add cream after thawing and reheat gently. Creamy soups can separate when frozen and reheated, so finishing with fresh cream helps restore a smooth texture.
