4 oz cream cheese, softened
-
2 cups sharp cheddar cheese, freshly shredded
-
1 cup mozzarella cheese, shredded

🔪 Step-by-Step Instructions
Step 1: Prepare the Cauliflower
-
Bring a large pot of salted water to a boil.
-
Add cauliflower florets and cook for 5–7 minutes until just fork-tender.
-
Do NOT overcook — soggy cauliflower will water down your sauce.
-
-
Drain thoroughly.
-
Spread cauliflower on a baking sheet and let it steam-dry for 10–15 minutes.
-
This removes excess moisture (important for a thick sauce).
-
💡 Pro Tip: You can also roast the cauliflower at 400°F (200°C) for 15 minutes instead of boiling for deeper flavor.
Step 2: Make the Cheese Sauce
-
In a large skillet over medium heat, melt butter.
-
Add minced garlic and sauté for 30 seconds until fragrant.
-
Pour in heavy cream and bring to a gentle simmer (do not boil).
-
Stir in cream cheese and whisk until smooth.
-
Reduce heat to low. Gradually add cheddar, mozzarella, and parmesan.
-
Stir continuously until fully melted and smooth.
-
Add salt, pepper, paprika, and mustard powder. Taste and adjust seasoning.
The sauce should be thick, creamy, and rich.
Step 3: Combine
-
Add drained cauliflower into the skillet.
-
Gently fold until every floret is coated in cheese sauce.
-
Simmer for 2–3 minutes to allow flavors to combine.
At this point, it’s ready to serve as a stovetop version.
🔥 Optional Baked Version (Extra Comfort Food Style)
-
Preheat oven to 375°F (190°C).
-
Transfer cauliflower mixture into a greased baking dish.
-
Sprinkle extra cheddar on top.
-
Mix crushed pork rinds with melted butter and sprinkle over the top.
-
Bake for 15–20 minutes until bubbly and golden.
-
Broil for 2–3 minutes for a crispy top.
Let rest 5 minutes before serving.
