Step-by-Step Instructions

Roast the Vegetables:
Preheat your oven to 180 degrees Celsius or 350 degrees Fahrenheit. Trim the top off each garlic bulb to expose the cloves. Arrange the garlic cauliflower florets and thyme in a large baking dish. Drizzle with half the olive oil and season well with salt and pepper. Roast for 45 minutes until everything is golden and fragrant
Prepare the Roasted Garlic:
After roasting allow the garlic to cool slightly. Then squeeze the soft cloves out of their skins and set aside. Save four of the smaller cauliflower florets for garnish
Sauté the Leeks:
Heat the remaining olive oil in a large pot over medium heat. Add the chopped leeks and cook for about five minutes stirring occasionally until they soften but do not brown
Build the Soup Base:
Transfer the roasted cauliflower garlic and any pan juices into the pot. Pour in the stock and season again. Bring the mixture to a boil then lower the heat and let it simmer gently uncovered for 20 minutes
Blend Until Silky:

Add the Cream Optional:
If you are using cream stir it into the blended soup and warm it gently to combine. Taste and adjust seasoning
Prepare the Grilled Cheese:
Butter both sides of each bread slice generously. Layer the cheeses inside two sandwiches starting with cheddar followed by mozzarella and finishing with parmesan. Press the top slices on

Storage Tips

Let the soup cool completely before transferring to containers. Store in the fridge up to four days or freeze for up to two months. Reheat gently over the stove and add water or broth if it thickens too much

Ingredient Substitutions

You can use onion instead of leek but cook it a bit longer to mellow its sharpness. If you do not have fresh thyme a pinch of dried thyme works too. For a dairy free version skip the cream and use plant based butter and cheese

Serving Suggestions

This soup pairs wonderfully with grilled cheese or a green salad with lemon vinaigrette. You can also top it with crispy chickpeas or croutons for added texture
