That’s a smart follow-up! Since the recipe for the Keto Creamy Cauliflower & Spinach Soup can be customized, the nutritional facts will vary.
Key Keto Metrics Explained
- Net Carbs: This is the most important number for Keto. It is calculated as Total Carbs minus Dietary Fiber. At 5–8 grams per serving, this soup is a solid Keto meal.
- High Fat: The high-fat content from the heavy cream, cream cheese, and butter/oil is what makes this soup satisfying and supports ketosis.
- Nutrient-Dense: Cauliflower and spinach provide essential micronutrients like Vitamin C, Vitamin K, and Folate.
💡 To Adjust the Nutrition:
- To Lower Calories/Fat: You can reduce the amount of heavy cream and skip the cream cheese. This will make the soup less rich, but still low-carb.
- To Increase Protein: Add 3-4 ounces of cooked shredded chicken, ground beef, or crumbled bacon to the final soup. This will significantly boost the protein content (by about 20-30 grams) and make it a complete meal.
📝 Instructions For Cauliflower & Spinach Soup
- Sauté Aromatics:
- In a large pot or Dutch oven, melt the butter or ghee over medium heat.
- Add the chopped onion and celery. Sauté for 5-7 minutes until the onion is translucent and the celery is slightly softened.
- Add the garlic and any dry spices (turmeric, cumin, etc.) and cook for 1 minute until fragrant.
- Cook Cauliflower Base:
- Add the cauliflower florets to the pot. Stir to coat them with the butter and aromatics.
- Pour in the low-sodium broth. Bring the mixture to a boil, then reduce the heat to a simmer.
- Cover and cook for 15-20 minutes, or until the cauliflower is very fork-tender.
- Blend and Thicken:
- Remove the pot from the heat. Carefully use an immersion blender to purée the soup until it is completely smooth and creamy. (Alternatively, carefully transfer the soup in batches to a regular blender, venting the lid for steam.)
- Return the puréed soup to the stovetop over low heat.
- Finish the Soup:
- Stir in the heavy cream and the cream cheese (if using, whisk until completely melted and smooth).
- Add the spinach and cook for 1-2 minutes until it is wilted.
- Taste and adjust seasoning with salt and pepper.
- Serve:
- Serve hot! You can garnish with a drizzle of olive oil, a swirl of heavy cream, or some shredded parmesan cheese for an extra boost of fat and flavor.
This soup has a similar texture and warmth to the lentil soup but is high in fat and low in net carbs, making it fully Keto-compliant.
Diabetic Friendly?
Yes, the Keto Creamy Cauliflower & Spinach Soup is generally Diabetic-Friendly.
While the soup was specifically designed to be low-carb for a Keto diet, this makes it inherently beneficial for blood sugar management as well.
✅ Why Cauliflower & Spinach Soup Diabetic-Friendly
- Extremely Low in Carbohydrates:
- This is the most critical factor. The Keto soup uses non-starchy vegetables like cauliflower and spinach as the base instead of high-carb ingredients like lentils (in the original recipe), potatoes, or bread.
- Fewer carbohydrates means the body has much less glucose (sugar) to process, leading to a much smaller and slower impact on blood sugar levels.
- Rich in Fiber:
- Cauliflower and spinach are excellent sources of dietary fiber. Fiber slows down the digestive process, which ensures that any small amount of carbohydrates consumed enters the bloodstream slowly and steadily, preventing sharp blood sugar spikes.
- Source of Healthy Fats and Protein (If added):
- The cream and fat base (butter/ghee) and any added protein (like chicken or bacon) contribute to feeling full and satisfied. Fat and protein help keep you feeling satiated for longer, which can assist in overall calorie control and prevent snacking on less healthy, high-carb foods later.
⚠️ A Note on Preparation
To keep it as healthy as possible for a diabetic diet, follow these simple guidelines:
- Use Low-Sodium Broth: Always choose low-sodium or unsalted vegetable or chicken broth/stock to manage blood pressure, which is often a concern for people with diabetes.
- Monitor Saturated Fat: While the Keto diet is high in fat, consult with your doctor or a dietitian about the amount of saturated fat (from heavy cream and butter) appropriate for your specific heart health goals, as heart disease risk is higher with diabetes.
