Ingredients for Keto Cauliflower Soup
- 1 medium head cauliflower (~700 g, cut into florets)
- 2 tbsp butter
- 2 garlic cloves, minced
- 500 ml chicken or vegetable broth (sugar-free or homemade)
- 150 ml heavy cream (33%+ fat)
- 50 g cream cheese (or shredded cheddar — optional)
- Salt and pepper to taste
- Pinch of nutmeg (optional)
- Optional topping: cooked bacon bits (+40–50 kcal per serving) or fresh herbs
Instructions
- Sauté: In a large pot, melt the butter over medium heat. Once fully melted and gently bubbling, add the minced garlic. Cook for about 30 seconds, stirring constantly, just until fragrant. Be careful not to brown the garlic — this step is meant to release aroma, not create color, as burnt garlic can turn bitter and affect the final taste of the soup.
- Simmer: Add the cauliflower florets to the pot, then pour in the broth. Stir to combine, increase the heat slightly, and bring the soup to a gentle simmer. Reduce the heat and cook for approximately 15 minutes, or until the cauliflower is very soft and easily pierced with a fork. Proper softness is key for a smooth, creamy texture later.
- Blend: Remove the pot from the heat. Using an immersion blender, carefully blend the soup until completely smooth and velvety. Take your time and blend thoroughly to eliminate any remaining chunks.
- Finish: Stir in the heavy cream and cream cheese or cheddar, if using. Season with salt, black pepper, and a pinch of nutmeg if desired. Mix well until everything is fully melted and incorporated.
- Heat gently: Return the soup to low heat and warm for 2–3 minutes. Do not let it boil, as high heat can cause the dairy to separate.
- Serve: Ladle the soup into bowls and garnish with crispy bacon or fresh parsley if desired.
