Why Make This Recipe?
Yup, there are lots of vegan cauliflower mashed potato recipes out there so why make this one? Not only is mine absolutely delicious, (you can call all my friends and relatives and ask if you don’t believe me), but it’s also:
- nutrient-friendly – cauliflower is not only low in calories, but it’s high in dietary fiber, which is associated with protection against gastrointestinal diseases, constipation, hemorrhoids, colon cancer, diabetes, stroke, high blood pressure and heart disease. In addition, it’s loaded with vitamins and minerals, especially vitamin C, a powerful antioxidant associated with a lower risk of heart disease. As a cruciferous vegetable, it’s high in glucosinolates and isothiocyanates, two antioxidants that have been found to slow the growth of cancer cells.
- quick and easy – recipe is easy to make, requires only 8 ingredients and is ready in less than an hour. *TIP: to shorten preparation time, steam cauliflower rather than roast it, which shortens prep time to 15 minutes.
- dietary restriction-friendly – suitable for all diets, including vegan, vegetarian, low-fat, low-calorie and gluten-free.
- ingredient-friendly – of the 8 ingredients required for this recipe, many may already be in your pantry.
- budget-friendly – recipe costs approximately $9 to make, if you don’t have any of the listed ingredients.
- equipment-friendly – most of this equipment you’ll already have in your home, including a sheet pan, a large mixing bowl, an immersion blender, food processor, or hand mixer, and a wooden spoon.
What You’ll Need
Ingredient Notes and Substitutions
- garnishes – I used parsley and rosemary, but feel free to improvise with other herbs including fresh sage or thyme, or whatever dried herbs you have in your pantry.
- plant milk – I typically use oat milk in my recipes, however you can use any plant milk of your choosing.
- vegan butter – if not keen on vegan butter, you may omit completely and/or substitute with more plant milk and olive olive oil.
How to Make Roasted Cauliflower Mashed Potatoes
Step 1 – Preheat oven to 425F/218C. Line a baking sheet with parchment paper. Place cauliflower and garlic on lined baking sheet. Mix olive oil and garlic powder in small bowl and brush each side with a thin veil of mixture. Alternatively, you can omit roasting cauliflower and garlic altogether by steaming or boiling cauliflower on the stove and mincing the garlic before mashing.
Step 2 – Roast for 30-45 minutes, or until fork tender, turning half way through.
Step 3 – Remove from oven. Place roasted cauliflower and garlic in large mixing bowl.
Step 4 – Using an immersion blender, begin blending florets and garlic. Add vegan butter and plant milk a little at a time until mixture reaches a consistency similar to mashed potatoes. Season with sea salt and black pepper to taste and give one final stir.
Step 5 – Place in serving bowl. Garnish with more vegan butter, rosemary and parsley. Serve immediately.
