To create a healthy homemade potato soup, substitute cauliflower for heavy cream. When roasted, the cauliflower also adds a creamy, nutty flavor that complements the other ingredients in the soup.
Healthy homemade potato soup contains calcium, vitamin C, vitamin B6, phosphorus and vitamin B12. However, this soup is high in saturated fats because of its dairy content, which includes milk, sour cream and cheese. To reduce the amount of saturated fats, choose low-fat dairy products to combine with the cauliflower.
After roasting, puree the cauliflower with low-fat or slim milk. Cook and then puree potatoes, herbs and seasonings such as green onion, salt and pepper. For an added health benefit, leave the skin on the potatoes. In a pot, combine potatoes, cauliflower and sour cream or low-fat cheese. Heat on low until warm. Add salt and pepper to taste.
Ingredients commonly used as a garnish for potato soup include bacon and croutons. For a healthier alternative, substitute turkey bacon for pork bacon, or just add green onion for color and texture instead. Sauté chickpeas until crisp, and place them on top of the soup instead of croutons.
Cauliflower may also serve as a substitute for mashed potatoes and rice. Additionally, use cauliflower to make pizza dough or as a substitute for flour when baking cookies.
