    How To Make Keto Mashed Potatoes Recipe: Step-By-Step Guide

    Cooking methods

    • Boiling

    Preparation steps

    1. Gather and measure all the ingredients. 
    2. Cut the cauliflower into florets and wash them thoroughly.
    3. Finely chop the garlic cloves. 
    4. Rinse the fresh chives or parsley and chop them for garnish.

    Cooking instructions

    1. In a large pot, bring water to a boil. Add the cauliflower florets and boil for 8-10 minutes until tender. 
    2. Once the cauliflower is cooked, drain the florets well in a colander. 
    3. In a blender or food processor, add the cooked cauliflower, butter, heavy cream, garlic, sea salt, and black pepper. Blend until smooth and creamy. You may need to scrape down the sides occasionally to ensure even blending.
    4. If the mash is too thick, add more heavy cream a little at a time until you reach your desired consistency.
    5. Transfer the keto mashed "potatoes" to a serving bowl and garnish with chopped chives or parsley for extra flavor and presentation. 

    Chef's pro tip

    To get the perfect creamy texture, make sure the cauliflower is well-drained after cooking. If you have extra time, set the boiled florets in a pan over medium heat for a few minutes to dry out excess moisture. 

    What To Serve With Keto Mashed Potatoes 

    This keto mashed "potatoes" is a great keto side dish to serve with the following options: 

    • Grilled steak: Rich, savory steak pairs well with creamy cauliflower mash, offering a classic combo. 
    • Roast chicken: Serve the mashed cauliflower with perfectly roasted chicken for a delightful dinner. 

    Time-Saving Tips

    • Use pre-cut frozen cauliflower florets to cut down on prep time. Simply steam or boil them according to package instructions.

    What Can I Prepare Ahead Of Time?

    • Steam or boil the cauliflower ahead of time and store it in the fridge for up to 2 days. When you're ready to serve, reheat and blend it with the remaining ingredients.

    Storage And Reheating Instructions

    Storage instructions

    • Refrigerator: Store the mashed cauliflower in an airtight container in the refrigerator for up to 3-4 days.

    Best Reheating Instructions

    • Stovetop: Reheat the mashed cauliflower over low heat in a saucepan, stirring occasionally. Add a splash of cream or butter to restore its creamy texture.
    • Microwave: Reheat the leftover mash in a microwave-safe dish in 30-second intervals, stirring in between, until fully heated.
