Ingredient Notes & Substitutions
Cauliflower
The foundation of this dish. Use fresh cauliflower for best texture - frozen results in a less appealing consistency.
Substitutions: Broccoli (not ideal), Cauliflower rice (requires different preparation)
Butter
Adds richness and helps create the velvety texture. Salted butter will adjust seasoning needs.
Substitutions: Ghee, coconut oil (adds subtle coconut flavor)
Heavy Cream
Provides the signature creamy texture. Can be substituted with whole milk for lower fat, but texture will differ.
Substitutions: Half-and-half, full-fat coconut milk

Fresh garlic is essential for optimal flavor. Minced garlic paste will work in a pinch.
Substitutions: Garlic powder (use 1/2 tsp), roasted garlic
Pro Tips for Perfect Cauliflower Mash
Texture Mastery
Roast until tender but not overdone. Undercooked cauliflower won't blend smoothly while overcooked becomes gummy.
Flavor Boost
Add 1/4 tsp of nutritional yeast for umami depth or a pinch of smoked paprika for a smoky twist.
Make Ahead
Prepare roasted cauliflower up to 24 hours in advance. Store in airtight container in fridge.
Serving Hack
Transfer to serving bowl immediately after blending. Keeps texture light and prevents separation.
Variations & Customizations
Cheesy Comfort
Add 1/2 cup grated Parmesan for extra richness and a hint of dairy flavor.
Herb-Infused
Mix in 1 tbsp fresh parsley and 1 tsp dill for a springtime twist.
Spicy Kick
Add 1/2 tsp cayenne pepper or 1/4 tsp hot sauce for a fiery version.
Vegan Option
Use vegan butter and plant-based cream for a dairy-free version.
