This creamy keto cauliflower soup is a comforting, flavorful bowl that’s ready in about 30 minutes. Fresh garlic, chicken or vegetable stock, and green onions build the base flavor while tangy goat cheese creates a silky texture.
Cauliflower is an excellent low-carb alternative to starchy ingredients like potatoes or rice. When steamed and pureed, it develops a smooth, hearty texture that makes this soup feel like a classic potato soup—without the extra carbs.
If you like a little heat, try a spicy cauliflower rice dish such as a keto pork curry over cauliflower rice for a quick, 30-minute meal.
Why This Recipe Works
Here’s why this Keto Cauliflower Soup is a great choice:
Simple, effective cooking – The cauliflower is steamed with garlic, onion, and parsley to maximize flavor while keeping prep quick.
Silky texture – Pureeing the steamed cauliflower with stock yields a smooth, creamy consistency.
Goat cheese for richness – Goat cheese melts into the soup, adding creaminess and a mild tang that elevates the overall flavor.
Ready in 30 minutes – A fast, satisfying option for weeknights or when you want a warm, low-carb meal.
Low carb – This soup is a considerably lower-carb alternative to potato-based soups, making it suitable for keto and low-carb diets.
What’s In It
Fresh, wholesome ingredients make this soup bright and satisfying.
Cauliflower – one large head of cauliflower (or two bags of florets if preferred).
Broth or stock – chicken or vegetable stock, used to thin and flavor the puree.
Goat cheese – adds creaminess and a pleasant tang; can be substituted with cream cheese if desired.
Green onions – use the white parts when steaming and the green tops to garnish.
Optional toppings – cooked crumbled bacon, shredded cheddar, or fresh parsley make great garnishes.
How to Make It
Quick steps to a smooth, flavorful soup:
(1) Trim the cauliflower, cut into small florets, and rinse. Place cauliflower pieces with garlic, the white part of the green onions, and parsley into a large microwave-safe bowl. Add 2–3 tablespoons water, season with salt and pepper, cover, and microwave on high for 6–7 minutes or until tender.
(2) Transfer about half of the steamed cauliflower mixture to a blender (fill no more than halfway), add 1 cup of stock, and puree until smooth. Vent the blender lid slightly to allow steam to escape.
(3) Pour the puree into a pot. Repeat with the remaining cauliflower and stock, blending and adding to the pot. Warm the combined soup over medium heat for about 5 minutes.
(4) Stir in 4 ounces of goat cheese until melted and fully incorporated. Adjust seasoning with salt and pepper. If the soup is too thick, add additional stock to reach the desired consistency.
(5) Serve in bowls and garnish with thinly sliced green onion tops and optional crumbled bacon or herbs.
Ways to Cook Cauliflower
Choose the method that fits your equipment and schedule. Cooking times vary by appliance and quantity.
- Microwave-steamed: cover cauliflower with a small amount of water in a bowl and microwave for 6–7 minutes.
- Boiled: simmer florets in boiling water for 6–7 minutes, then drain.
- Roasted: toss florets with olive oil and roast at 425°F for 20–25 minutes for caramelized flavor.
- Air-fried: toss in oil and air fry at 380°F for 8–12 minutes until tender and lightly browned.
How to Cut Cauliflower
If you need a quick refresher on cutting a whole head of cauliflower, look for a basic tutorial that demonstrates removing outer leaves, cutting the stem, and separating florets. Properly trimmed florets cook more evenly and blend more smoothly.

Tips and Substitutions
- Choose cauliflower that is firm, bright, and free from brown spots.
- If you don’t have a blender, an immersion blender works well and lets you puree the cauliflower right in the cooking bowl or pot.

- Alternative toppings include shredded cheddar, chopped parsley, chives, or a drizzle of olive oil.
