Ingredients
Makes one 9×13-inch casserole. Gather:

- 3 cups cauliflower florets, steamed and coarsely chopped (or 2½ cups cauliflower rice)
- 1 cup heavy cream or full-fat coconut milk
- 8 oz cream cheese, softened
- 1 cup shredded mozzarella (or cheddar)
- ½ cup grated Parmesan
- 2 cloves garlic, minced
- 1 small onion, finely diced
- 1 tsp dried thyme
- 1 tsp paprika
- ½ tsp salt and ¼ tsp black pepper
- 2 tbsp butter or olive oil
- 2 tbsp almond flour (for a light topping) or ¼ cup crushed pork rinds (optional)

Step-by-step instructions
- Preheat and prep: Preheat oven to 375°F (190°C). Lightly grease a 9×13 pan.
- Sauté aromatics: In a skillet, heat butter over medium heat. Sauté onion until translucent, add garlic, and cook 30 seconds more.
- Make the creamy base: Lower heat and stir in cream cheese until melted. Add heavy cream and whisk until smooth. Stir in thyme, paprika, salt, and pepper.
- Combine: In a large bowl, mix shredded chicken, steamed cauliflower, and cheesy sauce. Fold in half the mozzarella and all the Parmesan.
- Assemble: Pour mixture into prepared pan and spread evenly. Sprinkle the remaining mozzarella on top and finish with almond flour or crushed pork rinds for texture.
- Bake: Bake 20–25 minutes until bubbly and golden on top. Let rest 5–10 minutes before serving.
This family-tested Creamy Low-Carb Chicken Casserole stays moist and comforting even if you let it rest; the flavors marry best after a brief cool-down.
Tips for success
- Use warm chicken straight from cooking — it absorbs sauce better than cold meat.
- Don’t overcook cauliflower; it should be tender but not mushy so the casserole keeps structure.
- For a silkier sauce, blend the cream and cream cheese before adding to the pan.
- If you want extra browning, switch oven to broil for the last 1–2 minutes, watching closely.
- For lower sodium, use unsalted cheese and adjust seasonings at the end.

Possible variations
- Gluten-free: This recipe is naturally gluten-free when you use almond flour for the topping; always check labels on processed cheeses.
- Streusel topping: For a fall-inspired crunch, mix ¼ cup almond flour, 2 tbsp cold butter, ¼ tsp cinnamon, and a pinch of salt; crumble over the casserole before baking.
- Veggie-packed: Add sautéed spinach, mushrooms, or chopped broccoli for more color and nutrients.
- Cheesy twist: Swap mozzarella for sharp cheddar or a smoked cheese for deeper flavor.
- One-pan option: Brown onions and chicken in an ovenproof skillet, add sauce and cauliflower, then finish under the broiler for a crisp edge.
