FAQ
Is keto cauliflower mashed potatoes really a good substitute for traditional mashed potatoes?
Yes. While it does not taste exactly like potatoes, cauliflower mashed potatoes offer a creamy texture and savory flavor that works very well as a low-carb alternative.
Is this dish suitable for a keto diet?
Yes. Cauliflower is naturally low in carbohydrates, and the added fats from butter, olive oil, and sour cream make it keto-friendly.
Can I make this recipe dairy-free or vegan?
Yes. You can replace butter with vegan butter or olive oil, omit the Parmesan cheese, and use a dairy-free sour cream alternative to make it vegan.
Why roast the cauliflower instead of boiling it?
Roasting removes excess moisture and adds a deeper, richer flavor. This helps prevent the mash from becoming watery.
How do I make the mash extra creamy?
Blending thoroughly in a food processor and adding sour cream or butter gradually will help achieve a smooth, creamy consistency.

Yes. You can prepare them in advance and store them in the refrigerator for up to 3 days. Reheat gently before serving.

It can be frozen, but the texture may change slightly after thawing. Re-blending or stirring well after reheating can help restore creaminess.
