  • 1 lb ground beef
  • 1 teaspoon fennel seed
  • 1/2 teaspoon Italian spice seasoning
  • 1 teaspoon paprika
  • 2 cups cauliflower florets
  • 1/2 cup Parmesan cheese, grated
  • 1/4 cup cream cheese (2 oz)
  • 1/2 cup heavy cream
  • 1 egg, beaten
  • 1 cup marinara sauce (I used Specialty Selects)
  • 1 cup mozzarella cheese, shredded


  1. Preheat oven to 400 degrees F.

  2. Add the beef to a skillet along with the fennel, Italian seasonings and paprika. Cook until browned.

  3. In the meantime place the cauliflower in the microwave and cook for 5 minutes.

  4. Once brown, add in cauliflower mix and then spoon into a baking dish. Note* I used a leaner ground beef. If you use a fattier ground beef and have a lot of grease, please drain it before adding the cauliflower.

  5. To mkae the cheese sauce, in the skillet add the cream cheese, cream and Parmesan cheese. Whisk until the cheeses are melted then take it off the stove and let cool a bit.

  6. Add in the beaten egg to the cooled cheese sauce, whisk and then pour over meat and cauliflower mixture.

  7. Spoon the sauce onto the casserole and then top with mozzarella cheese.

  8. Bake 30 minutes until brown and bubbly.
