Creamy, dairy-free and dee-lish thanks to roasting the vegetables which adds so much flavor and depth! Topped with more roasted vegetables for texture, it's both filling yet light.
Line a large baking sheet with foil and spray with oil. Place the cauliflower and the brussels cut side down on the baking sheet, drizzle with oil and roast on the bottom third of the oven 25 minutes, tossing half way until slightly browned.
Meanwhile, melt the butter in a large sauce pan over low heat and add shallots. Cook until translucent, about 5 minutes. Add the salt and broth and simmer for 5 minutes.
Shut the oven off, reserve about 1 generous cup of the roasted vegetables and keep warm on the baking sheet.
Transfer the rest to the pot and simmer 2 minutes.
Transfer in two batches to the blender and blend until smooth.
Serve in 4 bowls topped with the roasted vegetables and fresh black pepper, to taste. Serve immediately.
