Roasting the Cauliflower:
Preheat your oven to 400°F (200°C).
Toss the cauliflower florets with olive oil, salt, and pepper.
Spread them evenly on a baking sheet.
Roast for 20-25 minutes or until the edges are golden and crispy.
Prepping the Base:
While the cauliflower is roasting, heat the olive oil in a large pot over medium heat.
Add the diced onions, stirring occasionally until translucent (about 5 minutes).
Stir in the garlic and ginger, sautéing for an additional 2 minutes.
Sprinkle in the ground turmeric, stirring well.
Bringing the Soup Together:
Pour in the vegetable broth and coconut milk to the pot.
Bring the mixture to a simmer.
Add the roasted cauliflower to the pot.
Allow it to simmer for 10-15 minutes, letting the flavors meld.
Season with salt, pepper, and a squeeze of fresh lemon juice.
Blending (Optional):
If you prefer a smoother Roasted Cauliflower and Turmeric Soup, use a hand blender to puree the soup until smooth.
