Vegan mashed cauliflower with rosemary and garlic is creamy, buttery, and ready in just 15 minutes! Using frozen cauliflower makes this side dish quick and easy to prep.
Steam 15 ounces frozen cauliflower florets in the microwave as per instructions on the bag. This usually takes 4 to 5 minutes.
While the cauliflower cooks, sauté 4 cloves garlic and ½ teaspoon fresh rosemary with 1 tablespoon olive oil in a small pan over medium heat for 2 to 3 minutes or until the garlic is aromatic and slightly browned.
Add the steamed cauliflower, 3 tablespoons vegan butter, 3 tablespoons unsweetened soy milk, ½ teaspoon sea salt , ¼ teaspoon black pepper, and sautéed garlic and rosemary to a food processor.
Process the mixture for 2 to 5 minutes. Scrape down the sides between processing. Add more milk or butter as needed to achieve a smooth, creamy consistency. Be careful about over-processing the mixture, or it will become gloopy.
Add more salt and pepper to taste. Top with chives or green onions and enjoy!
Notes
Frozen Cauliflower: Originally I tested this with a 15-ounce bag of cauliflower. I have also more recently tested it with a 10-ounce bag, I decreased the amount of butter to 2 tablespoons and soy milk to 2 tablespoons. I left everything else the same and it turned out great.Storage: Store vegan mashed cauliflower in an airtight container in the refrigerator for 3 to 5 days. For freezing, divide the mashed cauliflower into freezer-safe containers or resealable freezer bags, leaving space at the top for expansion. Store them in the freezer for 2 to 3 months.Reheating: When ready to enjoy your mashed cauliflower, thaw it in the refrigerator overnight or reheat it directly from frozen in a saucepan over medium-low heat. Add a splash of non-dairy milk as needed. Stir occasionally until thoroughly heated to maintain its flavor and consistency.
