How to make Cauliflower Bisque
Preheat the oven to 425F and line a baking sheet pan with parchment paper.
- Cut the top off of a bulb of garlic to expose the cloves. Place the bulb on the sheet pan with the cauliflower florets. Drizzle everything with olive oil and sprinkle with salt. Bake in the oven for 20 minutes.
- While the cauliflower is roasting, chop up the peeled carrots, celery, and onion.
- Place a soup pot on medium heat. Drizzle in a little olive oil and add in the chopped veggies. Cook until the onions are translucent. Stir in the corn kernels, tomato paste, and Old Bay seasoning.
- Deglaze the soup pot with the broth. Add in the roasted cauliflower. Squeeze the roasted garlic cloves out of the bulb, and into the soup. Bring the soup to a simmer, cover, and cook for 15 minutes.
5. Remove the soup from the heat. Use am immersion stick blender to puree the soup.
6. Pour the heavy cream in a small bowl. Stir in a ladle of the pureed soup in order to temper the cream and prevent splitting it. Once the cream has warmed up, pour it back into the soup while stirring.
Storage
Transfer the cooled Cauliflower Bisque Soup into an airtight container and refrigerate for up to four days. Freeze the soup in freezer-safe containers or bags, leaving room for expansion, and store for up to three months. Thaw the soup overnight in the refrigerator before reheating. Reheat gently on the stovetop over medium heat, stirring occasionally until warmed through. Add a splash of broth or cream if the soup has thickened to restore its silky texture.
