How to Make Keto Sweet Potato Casserole Recipe

Step 1: Prepare the Cauliflower

Start by cutting the cauliflower into florets. Then steam or boil until it’s very tender—this is key to achieving that creamy texture in the finished casserole.

Step 2: Drain and Dry

Once cooked, drain the cauliflower thoroughly and let it sit so any excess moisture evaporates. This prevents the casserole from becoming watery later on.

Step 3: Blend the Filling

Transfer the dried cauliflower to a food processor. Add butter, cream cheese, heavy cream, eggs, your chosen low-carb sweetener, ground cinnamon, nutmeg, vanilla extract, and salt. Blend everything until incredibly smooth and creamy.

Step 4: Assemble the Casserole

Grease your casserole dish lightly, then spread the smooth cauliflower mixture evenly inside. This creamy base will soon be topped with a crunchy, delicious layer.

Step 5: Prepare the Topping

Mix together chopped pecans, unsweetened coconut, and sugar-free maple syrup. This combination will create the signature sweet and nutty crunch that makes this Keto Sweet Potato Casserole Recipe so irresistible.

Step 6: Bake to Perfection

Sprinkle the topping evenly over the cauliflower base, then bake at 350°F until the casserole is bubbling hot and the topping turns a beautiful golden brown. Let the casserole rest a few minutes before serving so the flavors settle beautifully.

Make Ahead and Storage

Storing Leftovers
