Keto sweet potato cauliflower casserole

  • 1 head small head cauliflower (see notes below)
  • 1 cup Canned pumpkin
  • 1/2 cup Unsalted Butter (8 TB or full stick)
  • 3/4 cup granulated sweetener
  • 1 tablespoon vanilla extract
  • 1/2 teaspoon Salt
  • 1 teaspoon liquid monk fruit (optional, see notes below)
  • 3 large Eggs

Brown sugar pecan crust

  • 1/2 cup Besti Brown Sugar Sweeneter (can use Swerve as well 1:1)
  • 1/2 cup blanched almond flour
  • 1/2 cup chopped pecans
  • 1/4 cup Unsalted Butter (4 TB)


sweet potato cauliflower bottom

  • Chop and wash head of cauliflower then boil to fork tender. Should be so tender it its falling off the fork and easily pierced.
  • Drain then add cauliflower into food processor and grind into a smooth puree
  • Now combine mashed cauliflower, pumpkin puree, melted butter, granulated sweetener, vanilla extract, salt, liquid stevia and eggs together
  • Prepare the topping by follow instructions below and preheat oven to 350ºF

brown sugar pecan crust

  • Melt butter
  • Combine with Besti brown sugar, blanched almond flour, and butter. Then add pecans to finish
  • Add the topping to the cauliflower casserole. Place crumbles throughout as evenly as possible
  • Option 1: Cover with aluminum foil and bake for 30 minutes. Remove foil then bake and additional 20-30 minutes until crust browns. I like a darker crust so I normally go the entire 30 extra minutes but ovens vary.
  • Option 2: Place casserole in preheated oven without the pecan topping for 30 minutes. After 30 minutes remove and add the topping then place back into the oven for another 30 minutes.


Helpful Recipe Tips

  • Small head of cauliflower, this is important due to the water content. The smaller the head the less water. If you use a larger one the "sweet potato" part won't set at all. Naturally, there's no starch so it is looser to begin with but there would be a clear difference in texture.
  • Watch the sweetness, I personally like to use liquid monk fruit to strengthen the sweetness in the bottom portion. For a sensitive pallet the top is more than enough sweet for the entire dish.
  • Ice cream topping, a trick I learned at Ruth Chris was topping the casserole with vanilla ice cream. This recipe is modeled after that version and if you have had the pleasure of having it, it's almost more of a dessert than a savory dish. Enjoy!
