In a soup pot, heat the remaining tablespoon of olive oil over medium heat. Add the onion and 1/4 tsp. salt. Stir occasionally, until the onion is softened.
Add the garlic and stir for about 30 seconds, then add the broth.
Transfer the roasted cauliflower to the pot and add the lemon zest. Increase the heat to medium-high and bring the mixture to a simmer.
