Ingredients

  • 2 heads fresh cauliflower (approx 8 cups chopped)
  • 2 tbsp butter
  • 1 block cream cheese
  • 2 cups heavy whipping cream
  • 12 oz sharp cheddar cheese, grated
  • 4 oz mozzarella cheese, grated
  • 4 oz parmesan cheese, grated
  • 1 tbsp garlic powder
  • 1 tbsp Italian Seasoning

  • 1 tsp parsley
  • salt/pepper to taste

Instructions

  • Preheat oven to 375°F and grease a 9" x 13" casserole dish.
  • Wash cauliflower and cut into bite-size florets (so that it resembles the size of mac noodles).
  • Add 1/4 cup water to a microwave-safe bowl with cauliflower and microwave for 10 minutes, then drain.
  • In a saucepan, add butter, heavy whipping cream, and garlic over medium heat. Add softened cream cheese and stir with a whisk until thoroughly combined and melted.
  • Then, add all of your cheeses stirring constantly reserving ¼ cup of the cheddar cheese for topping. 
  • In a large bowl, toss your cheese mixture with your cauliflower until fully coated in the sauce.
  • Pour it all into a casserole dish.
  • Top with the ¼ cup reserved cheddar cheese, paprika, Italian seasoning, and parsley.
  • Bake for 25 minutes. Enjoy!

Notes

Other macaroni and cheese add-ins:
  • I love adding crumbled bacon on top! It adds incredible flavor and a nice crunch!
  • If serving this as a meal, you can add shredded, sliced, or diced chicken to your sauce along with the cauliflower.
  • Diced ham would also be a great addition!
  • Try adding some pork panko to the top to mimic "breadcrumbs."
Tips:
  • If your cream was too hot when you added your cheese, it could affect the consistency of the cheese.
  • Make this ahead of time and store it in the fridge until you are ready to reheat it. It may just take a bit longer to bake since it is colder.
  • You can freeze this, but keep in mind that freezing cheeses and cream may affect the consistency and texture of your sauce. I suggest laying a piece of plastic wrap directly over top of your casserole then follow that with tin foil and a lid. Allow to defrost fully in the fridge overnight before baking and put in the oven while preheating so that it heats slowly. 
  • You can use frozen cauliflower: however, the texture may be different.
