1. In a large pot, heat the olive oil over medium heat. Add the chopped onion and minced garlic, sautéing until the onion becomes translucent and fragrant, about 3-4 minutes.
2. Add the diced carrots, celery, and potato to the pot. Stir well and cook for another 5 minutes, allowing the vegetables to begin softening.
3. Incorporate the zucchini and broccoli florets, stirring to combine all the vegetables evenly.
4. Pour in the vegetable broth, bringing the mixture to a gentle boil. Cover the pot and reduce the heat to a simmer, letting it cook for 15-20 minutes or until the vegetables are tender.
5. Using an immersion blender, carefully puree the soup to your desired consistency. If you prefer a chunkier texture, only blend half of the mixture.
6. Stir in the heavy cream and dried thyme, seasoning with salt and pepper to taste. Allow the soup to simmer for an additional 5 minutes.
7. Ladle the soup into bowls and garnish with freshly chopped parsley before serving.

This process is not just about following steps—it’s about feeling the rhythm of the kitchen, a lesson I learned from countless afternoons spent cooking alongside my abuela.
