Ingredients Breakdown
- 1 small head cauliflower, cut into florets (about 4 cups)
- 1 cup pumpkin puree (unsweetened; canned is perfect)
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 3 cups low-sodium chicken or vegetable broth
- 3 tbsp unsalted butter (or ghee for dairy-sensitive)
- 1/2 cup heavy cream (or full-fat coconut milk for dairy-free)
- 2 tbsp olive oil
- 1 tsp smoked paprika
- 1/2 tsp ground cumin
- 1/4 tsp ground nutmeg (just enough to whisper “fall”)
- Pinch of cayenne or red pepper flakes (optional, for heat)
- Salt and black pepper to taste
- 2 tbsp fresh sage or thyme, chopped (plus more for garnish)
- Optional toppings: crispy bacon, toasted pepitas, grated Parmesan, chives, sour cream/Greek yogurt swirl
Let’s Get Cooking – Instructions
- Roast the cauliflower: Preheat oven to 425°F (220°C). Toss cauliflower florets with olive oil, salt, and pepper on a sheet pan. Roast 20–25 minutes until browned on the edges.
This step makes the flavor pop. Don’t skip it.
- Sauté aromatics: In a large pot, melt butter over medium heat. Add onion and a pinch of salt; cook 4–5 minutes until translucent.
Stir in garlic for 30 seconds until fragrant.
- Spice it up: Add smoked paprika, cumin, nutmeg, and cayenne (if using). Toast spices for 30 seconds to wake them up. Your kitchen should smell ridiculous right now.
- Build the base: Add roasted cauliflower, pumpkin puree, and broth.
Stir well, scraping up any bits from the bottom of the pot. Bring to a gentle simmer.
- Simmer to marry flavors: Cook 10–12 minutes, partially covered. Taste and adjust salt and pepper.
If it’s too thick, add a splash of broth.
- Blend until silky: Use an immersion blender right in the pot. Or carefully transfer to a blender in batches. Blend until velvety smooth.
- Finish with cream and herbs: Return soup to low heat.
Stir in heavy cream and chopped sage or thyme. Warm through 2–3 minutes—do not boil.
- Garnish and serve: Ladle into bowls and top with your favorites: bacon, pepitas, Parmesan, fresh herbs, or a dollop of sour cream. Snap a pic.
You earned it.
How to Store
- Fridge: Store in an airtight container for up to 4 days. The flavors deepen by day two, FYI.
- Freezer: Cool completely and freeze up to 3 months. Leave out the cream before freezing and stir it in after reheating for best texture.
- Reheat: Warm gently on the stove over medium-low, stirring often.
Add a splash of broth or cream if it thickens.
Nutritional Perks
- Keto-friendly: Low net carbs thanks to pumpkin and cauliflower, not potatoes or flour.
- Fiber-forward: Pumpkin + cauliflower support digestion and help keep you full longer.
- Healthy fats: Butter and cream improve satiety and mouthfeel, keeping your macros balanced.
- Micronutrient-rich: Pumpkin brings vitamin A and antioxidants; cauliflower adds vitamin C and K. Your immune system says thanks.
Avoid These Mistakes
- Skipping the roast: Raw-simmered cauliflower works, but roasting adds caramelized depth. It’s the difference between “meh” and “wow.”
- Boiling the cream: High heat can split dairy and dull flavors.
Keep it to a gentle simmer at the end.
- Over-thinning: Add broth gradually. You can always thin more; thickening back up is a pain.
- Under-salting: Soup needs proper seasoning to shine. Taste after blending and adjust—don’t be shy.
- Using sweetened pumpkin: Double-check the label.
You want 100% pumpkin puree, not pie filling.
Variations You Can Try
- Dairy-free: Swap butter for olive oil or ghee and use full-fat coconut milk instead of cream. The subtle coconut note plays well with pumpkin.
- Protein boost: Stir in shredded rotisserie chicken or top with crispy pancetta. Satiety level: unlocked.
- Spicy Thai-ish: Add 1–2 tsp red curry paste and finish with coconut milk and lime juice.
Garnish with cilantro.
- Herb-forward: Replace sage with rosemary and thyme, and finish with a drizzle of herb-infused olive oil.
- Cheesy comfort: Blend in 1/2 cup grated aged cheddar or Parmesan at the end for a richer, nuttier vibe.
- Extra veg: Add a handful of spinach during the last minute of heating. It melts right in and adds color without drama.
FAQ
Can I use fresh pumpkin instead of canned?
Yes. Roast cubed sugar pumpkin or kabocha until tender, then measure 1 cup of puree.
Make sure it’s well-drained so the soup doesn’t get watery.
Is this soup suitable for meal prep?
Absolutely. It stores well and reheats like a champ. Keep toppings separate and add right before eating for best texture and crunch.
How can I make it thicker or thinner?
Thicker: reduce the broth or add more roasted cauliflower.
Thinner: splash in extra broth or a bit of water until it hits your preferred consistency.
What can I use instead of heavy cream?
Full-fat coconut milk or coconut cream works great. You’ll get a slightly tropical note, which pairs nicely with the spices, IMO.
Will this kick me out of ketosis?
In typical portions, no. Net carbs per serving are low, especially if you stick to unsweetened pumpkin and watch toppings.
Track your portions based on your daily targets.
Can I make it without a blender?
You can mash it with a potato masher for a rustic texture, but a blender gives that ultra-smooth, restaurant-style finish. If you’re a texture person, it’s worth it.
What protein pairs well on the side?
Try grilled sausage, roasted chicken thighs, or seared shrimp. The soup’s creamy base plays nicely with smoky, salty, or garlicky proteins.
