Ingredients
Instructions
- In a large saucepan, sauté the chopped onion in butter until soft.
- Stir in the flour and cook over low heat, stirring, for 3 minutes.
- Remove the pan from heat; add chicken broth, stirring, then add cauliflower and bring to a boil.
- Reduce heat and simmer for 30 minutes.
- Puree the mixture in a blender in two batches and return to the saucepan.
- Add milk, heavy cream, cayenne pepper, white pepper, and salt to taste.
- Cook until hot and serve sprinkled with minced parsley.
Tips & Substitutions
For a creamier texture, consider adding more heavy cream or using a hand blender instead of a traditional blender. If you're looking for a lighter option, substitute half of the heavy cream with additional milk. White pepper adds a subtle heat, but cayenne can be adjusted based on your spice preference. Fresh herbs like thyme can also enhance the flavor profile.
Serving Suggestions
Serve the soup hot, garnished with minced parsley. It pairs beautifully with crusty bread or a simple side salad for a complete meal. For a heartier option, consider serving alongside Oven Baked Potato Chip Chicken, which complements the soup's creamy texture.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the soup gently on the stovetop over medium heat, stirring occasionally. If the soup thickens, add a splash of milk or broth to reach your desired consistency.
