Serving Size: About 1 cup

Prep and Cook Time

  • Prep Time: 15 minutes
  • Cook Time: 30 minutes
  • Total Time: 45 minutes

Instructions

Preheat and Prepare

  1. Preheat the Oven
    Begin by preheating your oven to 375°F (190°C). This ensures your casserole will bake evenly and get that perfect golden crust.
  2. Boil the Cauliflower
    Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for about 5 minutes until slightly tender but still crisp. Drain and set aside.

Make the Creamy Cheese Sauce

  1. Prepare the Sauce
    In a saucepan over medium heat, combine the heavy cream, minced garlic, and Dijon mustard. Stir continuously until the mixture is hot, but do not let it boil.
  2. Add the Cheeses
    Gradually add in 1 1/2 cups of shredded cheddar cheese and all the Parmesan cheese. Stir until the cheeses are melted and the sauce is smooth. Season with salt, pepper, and paprika to taste.

Assemble the Casserole

  1. Combine the Ingredients
    In a large mixing bowl, combine the drained cauliflower florets with the cheese sauce. Gently fold until all the cauliflower is coated in that luscious sauce.
  2. Transfer to Baking Dish
    Pour the cheesy cauliflower mixture into a greased 9×13-inch baking dish, spreading it evenly.

Top and Bake

  1. Add the Topping
    Sprinkle the remaining 1/2 cup of shredded cheddar cheese on top, followed by the breadcrumbs for that delightful crunch.
  2. Bake Until Golden
    Place the casserole in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and bubbly.

Serve and Enjoy

  1. Garnish and Serve
    Once baked, remove the casserole from the oven and let it cool for a few minutes. Sprinkle with fresh parsley for a pop of color and serve warm.
