Making Roasted Garlic Cheddar Cauliflower Soup is straightforward when you follow these step-by-step instructions:

1. Roast the Garlic: Preheat your oven to 400°F (200°C). Cut the top off the garlic bulb, drizzle with olive oil, wrap in foil, and roast for 30-35 minutes until soft.
2. Prepare the Cauliflower: While the garlic is roasting, chop the cauliflower and onion.
3. Sauté the Onion: In a large pot, heat olive oil over medium heat. Add diced onion and sauté until translucent, about 5 minutes.
4. Add Cauliflower: Once the onion is ready, add the chopped cauliflower to the pot and stir well.
5. Add Broth: Pour in the vegetable broth, and season with salt, pepper, and paprika. Bring to a boil, then reduce the heat to a simmer.
6. Simmer: Cover and let simmer for about 15-20 minutes, or until the cauliflower is tender.
7. Incorporate Roasted Garlic: Squeeze the softened garlic cloves into the pot. Stir to mix thoroughly.
8. Blend the Soup: Using an immersion blender or a standard blender, blend the soup until smooth and creamy.
9. Add Milk and Cheese: Return the soup to the pot if using a standard blender. Stir in the whole milk and shredded cheddar cheese until melted and combined.
10. Adjust Consistency: If the soup is too thick, add more broth or milk until reaching the desired consistency.
11. Serve: Ladle the soup into bowls and garnish with fresh parsley. Enjoy your hearty bowl of Roasted Garlic Cheddar Cauliflower Soup!
