Low Carb Creamy Cauliflower Gratin


Cauliflower Gratin is probably one of the most ridiculously delicious, decadent and insanely addictive side dishes ever created.



  • 1 Head Cauliflower, cut into bite sized pieces
  • 2 Slices Bacon
  • 3 Tablespoons Butter
  • 3/4 Cup Onion, finely diced
  • 3 Cloves Garlic, minced
  • 1 /2 Cups Whole Milk
  • 2 Tablespoons Flour
  • 1 teaspoon Dijon Mustard
  • 3/4 Cup Cheese (White Cheddar, Smoked Gouda, Gruyere or Swiss work best)
  • 1/4 Cup Parmesan Cheese


  • 1/4 Cup Panko Breadcrubs
  • 1 Tablespoon Olive Oil
  • 1 Tablespoon Parmesan Cheese


  1. Preheat the oven to 375°F. Line a baking sheet with parchment paper. Spray a 2 qt casserole dish or 8×8 pan with cooking spray or oil. Combine the topping ingredients in a small bowl. Set everything aside.
  2. Cut the cauliflower into small bite sized pieces. (This recipe used 8 cups of chopped cauliflower.) Place them in a large bowl and drizzle with a little olive oil and season with some salt and pepper. Place the cauliflower on the baking sheet.  Place the 2 strips of bacon on the same baking sheet and cook in the oven for 15 minutes.
  3. Meanwhile begin the cheese sauce by melting 3 Tablespoons of butter in a small saucepan. Once melted, add the onions and cook for about 4 minutes or until translucent – add the garlic and season with a little salt and pepper. Cook for 30 seconds. Add the flour and stir to combine. Cook for 1-2 minutes.
    Slowly add the milk, whisking (or stirring) to combine.  Add the mustard.  Turn the heat off and add the 2 cheeses. Stir to combine.
  4. Take the pan out of the oven and spoon a few spoonfuls of the sauce on the bottom of the baking dish. Pour the cauliflower on top and pour over remaining sauce. Chop up the bacon and sprinkle on top.
  5. Sprinkle the breadcrumb mixture on top and place the dish back in the oven for 10 minutes or until bubbly and browned.
