Ingredients
  

Main Ingredients
  • 1 medium head cauliflower cut into florets
  • 1 cup roasted red pepper chopped
  • 28 oz canned tomatoes
  • 2 tbsp tomato paste
  • 1 medium onion diced
  • 3-4 cloves garlic minced
  • 4 cups vegetable broth
  • 1/2 to 3/4 cup buffalo hot sauce adjust to taste
  • 1-2 tbsp olive oil
  • 1/2 tsp red pepper flakes optional
  • 1 tsp smoked paprika optional
  • salt & black pepper to taste
  • 1/2 to 1 cup plant-based milk or cashew cream optional, for creaminess
Garnish
  • green onion, fresh herbs, or buffalo sauce drizzle for garnish

Method
 

  1. Preheat oven to 400 °F (200 °C). Toss cauliflower florets with olive oil, salt, and pepper (add smoked paprika if using). Spread on a baking sheet and roast for 20–25 minutes, turning halfway.
  2. In a large pot, heat olive oil. Add diced onion and sauté until translucent (3–4 min). Add garlic, red pepper flakes, and smoked paprika. Cook for 1 min.
  3. Add canned tomatoes, tomato paste, roasted red pepper, and broth. Add roasted cauliflower. Simmer for 10–15 min.
  4. Blend soup using immersion blender (or transfer to a blender). Blend to desired texture (smooth or chunky).
  5. Stir in buffalo hot sauce gradually, tasting as you go. Add plant milk or cashew cream for extra creaminess (if using). Adjust salt and pepper.
  6. Serve hot, garnished with green onion, herbs, or a buffalo drizzle.

Notes

Make it vegan by using vegetable broth and plant-based cream. Roast the cauliflower for deeper flavor. Use a mild buffalo sauce for less heat, or increase flakes for a spicier version.
