    Add the cauliflower to a microwave safe bowl, cover with a paper plate, and cook in the microwave for 10 minutes or until tender.  

    Drain the cauliflower well and pat it with paper towels, pressing gently to dry.  It's important to make sure it's dry so that it doesn't get watery when you bake it.

    ☑️ Storage Instructions

    Mashed cauliflower can be stored in an airtight container in the refrigerator for up to about 3 days. You can also freeze it, though the texture is best when it's freshly baked.

    💡 Tips for Making Loaded Cauliflower Casserole

    • While using a head of cauliflower is fine, buying prepackaged florets can save you time and a little clean up.
    • Because you want a thick consistency, using frozen cauliflower for this cauliflower casserole is not recommended, due to its moisture content.
    • If you can't find Mascarpone, you can always use cream cheese. It'll change the macros because cream cheese has more carbs, so make sure you take that into account.
    • You can change up the flavors of this casserole by swapping the cheddar for pepper jack or Colby, or any of your favorite melting cheeses.
    • If you have the extra time, roasting the cauliflower florets adds even more flavor.
    • If you love extra spice, add you can add chopped, fresh, or pickled jalapenos.
    • You can add leftover chopped chicken or ham for a complete meal.

    🔄 Cauliflower Mash Casserole Variations

    • Broccoli florets: Add steamed broccoli florets to the cauliflower mash for a broccoli and cheddar twist.
    • Jalapeños: Spice it up by adding diced jalapeños to the cauliflower mash for a hint of heat.
    • Caramelized onions: Include caramelized onions for a sweet and savory flavor.
    • Parmesan cheese: Mix in grated Parmesan cheese with the cheddar for an extra layer of cheesy goodness.
    • Herbs and spices: Experiment with herbs like thyme, rosemary, or chives, and spices such as paprika or cayenne pepper to enhance the flavor.
    • Greek yogurt: Swap the sour cream for Greek yogurt or a slightly tangier twist.
    • Cream cheese: You can use cream cheese instead of mascarpone, if you prefer.

    🍴 What to Serve Keto Cauliflower Casserole With

    Is Cauliflower Keto?

    Cauliflower is perfect for keto. In fact, it's commonly used as a substitution for potatoes and rice in many low carb recipes.

    Not only is cauliflower low carb, it's rich in fiber and nutrients like vitamin B6, vitamin C, and vitamin K. If you'd like to read more about the health benefits of cauliflower, check out this article.

    Why is My Baked Cauliflower Runny?

    Ensure the cauliflower is well-drained once it has been microwaved. Also, you only want to bake the casserole until it's bubbly. Over-baking can cause it to become watery.

    How Do I Give Cauliflower a Creamy Consistency?

    Use a food processor or immersion blender to get a smooth and creamy texture. Add a bit of sou cream or butter for extra richness.

    Can I Use Frozen Cauliflower for this Recipe?

    Technically, you can. Having experimented with both fresh and frozen, fresh is what I always recommend.

      Can I used frozen riced cauliflower?

        Frozen riced cauliflower won’t work in this recipe because it doesn’t blend smooth like fresh cauliflower florets. For the best creamy texture, I recommend sticking with fresh florets.

      Can this be made ahead to be baked the next day?

        You can, but it's best when cooked the same day it's prepared. You can always bake it and reheat it the next day.

      Just for clarification: are you saying in the recipe to butter the baking dish AND spray it with baking spray? Or did I misread that?

        You'll use a prepared baking dish that has been buttered or sprayed with nonstick spray.
