In a large pot, heat the 1 tablespoon of olive oil over medium heat. Add the 3 minced garlic cloves and sauté for about 1-2 minutes, or until fragrant. Be careful not to let the garlic brown, as it can turn bitter.
Next, pour in the 3 cups of chicken or vegetable stock and add the 3 cups of cauliflower florets. Bring the mixture to a boil, then reduce the heat and simmer for about 10-15 minutes, or until the cauliflower is tender.
Once the cauliflower is tender, carefully transfer the mixture to a blender or food processor. Blend until smooth and creamy. If you prefer a thinner consistency, you can add a bit more stock.
Pour the blended mixture back into the pot over low heat. Stir in the 1/2 cup of Parmesan cheese until well combined. Season with salt and pepper to taste. Allow the sauce to warm through, stirring occasionally.
