Ingredients Needed:

1 large head cauliflower (about 2 pounds): chopped into florets
3 tablespoons extra-virgin olive oil: for roasting and sautéing
¾ teaspoon fine sea salt (divided): to enhance flavor safely
1 cup chopped leek (white part only): gentler alternative to onion
4 cups homemade low histamine broth: freshly made, short-simmered
2 tablespoons ghee or olive oil (optional): for creaminess
Fresh parsley (optional): for garnish only if tolerated

How To Make Low Histamine Cauliflower Soup:

Roast the Cauliflower:
Preheat oven to 425°F. Toss cauliflower florets with 2 tablespoons olive oil and ½ teaspoon sea salt. Spread on a baking sheet and roast for 25 to 35 minutes until golden and soft, tossing halfway.

Sauté the Leeks:
In a soup pot, warm 1 tablespoon olive oil over medium heat. Add chopped leek and ¼ teaspoon salt. Cook for 5 to 7 minutes until soft, not browned.

Simmer the Soup:
Add the fresh broth to the pot. Reserve 4 nice roasted cauliflower florets for garnish. Add the remaining roasted cauliflower. Bring to a light simmer and cook for 20 minutes.

Blend Until Smooth:
Let soup cool slightly. Transfer in batches to a blender. Add ghee or olive oil if using. Blend until smooth. Taste and adjust salt if needed.

Serve and Garnish:
Serve warm with a roasted cauliflower floret on top and parsley if tolerated.
