Place 1 inch of water in a large pot or large saucepan with a pinch of salt and bring to a boil.
Add cauliflower florets to the boiling water and cook for 8 to 9 minutes or until tender-crisp. Drain cauliflower in a colander and set aside.
Butter a 9x13 baking dish; set aside.
Pour milk into the same pot that you used for the cauliflower, and set over medium heat. Add the cream cheese to the milk and whisk until cream cheese is completely melted.
Stir in dried parsley, garlic powder, chili powder, salt, and pepper. Add 1 cup shredded cheddar cheese and 1 cup shredded mozzarella cheese; gently whisk until cheeses have completely melted.
Add the cauliflower florets back into the pot, and using a large spoon, gently stir around until everything is covered in cheese sauce.
Transfer the cauliflower mixture to previously prepared baking dish; sprinkle with remaining cheddar cheese and set aside.
In a small bowl, combine pork rinds crumbs, parmesan, and melted butter; mix and stir until well combined. Sprinkle the pork rinds mixture in an even layer over the cauliflower.
Bake, uncovered, for 18 to 20 minutes, or until hot and bubbly.
In the meantime, dice the bacon and fry it to a desired crispness.
Garnish the baked casserole with the crispy bacon and fresh parsle,y and serve.
Notes
Keep cauliflower tender but firm to mimic pasta's bite, avoiding overcooking.
Add cheese gradually to the sauce, ensuring full melt before adding more.
You can swap the cheeses in the recipe for shredded Gruyere, Gouda, or Monterey Jack.
Feel free to adjust the spice blend to your preference.
