Ingredients
- 1 large head cauliflower, cut into florets
- 6 cups certified gluten-free vegetable stock
- 1 medium yellow onion, chopped
- 2 cloves garlic, minced
- 2 tbsp olive oil
- 1/2 cup unsweetened almond milk or coconut milk (full-fat)
- 1/2 tsp dried thyme
- 1/4 tsp nutmeg, freshly grated (optional)
- 1 tsp salt, or to taste
- 1/2 tsp black pepper, freshly ground, or to taste
Instructions
- 1
Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped yellow onion and sauté until it becomes translucent and softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant, being careful not to burn it.
- 2
Add the cauliflower florets to the pot, along with the dried thyme and optional nutmeg. Stir everything together to coat the cauliflower with the aromatics and oil. Cook for an additional 3-5 minutes, allowing the cauliflower to slightly soften.
- 3
Pour in the certified gluten-free vegetable stock, ensuring the cauliflower is mostly submerged. Bring the liquid to a rolling boil, then reduce the heat to low, cover the pot, and let it simmer gently for about 20-25 minutes, or until the cauliflower is fork-tender and easily pierced.
- 4
Carefully transfer the soup to a blender in batches, or use an immersion blender directly in the pot. Blend until the soup is completely smooth and velvety. If using a standard blender, be sure to vent the lid to allow steam to escape and avoid pressure buildup.
- 5
Return the blended soup to the pot (if not already there). Stir in the unsweetened almond milk or coconut milk to achieve your desired creamy consistency. Heat the soup gently over low heat, without boiling, for about 5 minutes until warmed through. Season generously with salt and freshly ground black pepper to taste.

Tips & Notes
- If substituting olive oil for butter, use about 3/4 the amount (olive oil is 100% fat, butter is ~80%).
- Any plant-based milk works here — oat milk (certified GF) gives the richest mouthfeel; almond milk keeps it lighter.
- Press or mince garlic rather than slicing for a more pungent flavor; slice for a milder taste.
