Cooking Instructions
Here’s a step-by-step walkthrough to make your soup perfect every time:
- Preheat your oven to 400°F (200°C).
- Prepare the cauliflower and garlic: Toss the cauliflower florets and garlic cloves with olive oil, a pinch of salt, and a touch of pepper. Spread them on a baking sheet.
- Roast: Roast in the oven for 25-30 minutes, until cauliflower edges are golden and garlic is soft and caramelized. This step is key for depth of flavor.
- Sauté the onion: In a large pot, melt butter over medium heat. Add the chopped onion and sauté for 5-7 minutes until translucent and fragrant.
- Add roasted vegetables: Transfer the roasted cauliflower and garlic into the pot with the onions. Stir gently.
- Add broth: Pour in the vegetable or chicken broth and bring the mixture to a simmer. Let it cook for 10-15 minutes so the flavors meld together.
- Blend until smooth: Use an immersion blender or a regular blender in batches to puree the soup until silky smooth.
- Add creaminess: Stir in heavy cream or your dairy-free alternative. Taste and adjust seasoning with salt and pepper.
- Serve hot, garnished with your choice of toppings like fresh herbs or crunchy elements.
