Cauliflower Casserole Bake

This casserole delivers everything people love about comfort food—creamy, cheesy, and fresh from the oven with a beautifully golden top. It offers a lighter alternative to traditional potato-based casseroles while still providing the same satisfying texture and rich flavor. Tender cauliflower florets are coated in a velvety cheese sauce and baked until bubbly, creating a dish that wins over even those who don’t usually reach for cauliflower.

Ideal for family dinners, potlucks, and holiday gatherings, this casserole is always a crowd-pleaser. Serve it alongside roasted chicken, grilled pork chops, or baked salmon for a complete meal. A crisp green salad or seasoned green beans make excellent companions, while rolls or garlic bread can round out the table for guests who enjoy a heartier spread.

🥦 Low-Carb Cheesy Cauliflower Casserole

📝 Ingredients

• 1 large head cauliflower (about 2–2½ lbs), cut into small florets
• 2 tablespoons butter
• 3 garlic cloves, finely minced
• 4 ounces cream cheese, softened
• ½ cup sour cream
• ¼ cup heavy cream
• 1½ cups shredded cheddar cheese, divided
• ½ cup shredded mozzarella cheese
• ¼ cup grated Parmesan cheese
• 1 teaspoon salt, or as needed
• ½ teaspoon black pepper
• ½ teaspoon onion powder
• ½ teaspoon smoked paprika (optional)
• 2 tablespoons chopped parsley or chives (optional)
• Nonstick cooking spray or extra butter for the baking dish

🍴 Directions

1. Heat the oven to 375°F (190°C) and lightly grease a 9×9-inch baking dish.
2. Wash the cauliflower, cut it into bite-sized florets, and pat dry.
3. Cook the cauliflower in lightly salted boiling water for 5–7 minutes, until just tender. Drain thoroughly and allow excess moisture to evaporate.
4. Melt the butter in a skillet over medium heat. Add the minced garlic and cook briefly until fragrant.
5. Lower the heat and stir in the cream cheese until smooth.
6. Add the sour cream and heavy cream, mixing well. Stir in 1 cup of cheddar cheese, the mozzarella, and Parmesan until fully melted and creamy.
7. Season with salt, pepper, onion powder, and smoked paprika.
8. Add the cauliflower to the sauce and gently toss until evenly coated.
9. Spoon the mixture into the prepared baking dish and spread evenly.
10. Top with the remaining ½ cup cheddar cheese.
11. Bake for 20–25 minutes, or until hot, bubbly, and lightly browned.
12. For extra color, broil for 2–3 minutes at the end of baking.
13. Let stand for 5 minutes before serving. Garnish with parsley or chives if desired.

💡 Tip: Leftovers reheat beautifully and often taste even better the next day. This casserole makes an excellent substitute for mashed potatoes or macaroni and cheese when you want a lower-carb option.
