Flavor and Texture

The first forkful gives you creamy richness from the cheese and cream, followed by the mild, savory notes of seasoned chicken. Sautéing the broccoli and cauliflower briefly keeps them bright and slightly crisp so the casserole doesn’t turn mushy. Cheddar on top crisps and bubbles into golden patches that add a lovely contrast to the smooth interior. Garlic and onion powders deepen the savory profile, while a pinch of paprika brings warmth and visual appeal. Overall, each spoonful hits creamy, cheesy, and subtly roasted vegetable notes.

Ingredients

– 2 cups cooked chicken breast, shredded or cubed
– 1 cup broccoli florets
– 1 cup cauliflower florets
– 1 cup cheddar cheese, shredded
– 1/4 cup cream cheese, softened
– 1 cup heavy cream
– 1 tablespoon olive oil
– 1 teaspoon garlic powder
– 1/2 teaspoon onion powder
– 1/4 teaspoon paprika
– 1/4 teaspoon salt
– 1/4 teaspoon black pepper

Step by Step Instructions

1. Preheat your oven to 375°F (190°C).
2. In a large skillet over medium heat, add the olive oil. Sauté the broccoli and cauliflower florets for about 5 minutes until they start to soften.
3. In a large mixing bowl, combine the cooked chicken, sautéed broccoli, and cauliflower.
4. In a separate bowl, combine the cream cheese, heavy cream, garlic powder, onion powder, paprika, salt, and black pepper. Mix until smooth.
5. Pour the cream mixture over the chicken and vegetables, stirring until everything is well-coated.
6. Transfer the mixture into a greased casserole dish, spreading it out evenly.
7. Sprinkle the shredded cheddar cheese evenly on top of the casserole.
8. Bake in the preheated oven for 20-25 minutes, or until the cheese is golden and bubbly.
9. Remove from the oven and let it sit for a few minutes before serving.

Tips for Best Results

Use chicken that’s slightly seasoned or simply salted to avoid competing flavors with the casserole base. Don’t overcook the broccoli and cauliflower in the skillet; you want them tender but with a hint of bite so they hold up after baking. If you prefer a lighter top, swap half the cheddar for a milder melting cheese or reduce to taste. Letting the casserole rest a few minutes after baking helps the sauce thicken, making it easier to serve neat portions. For a golden finish, briefly broil the casserole for 1 to 2 minutes, watching closely so the cheese doesn’t burn.

Storage and Make Ahead

Cool the casserole completely before refrigerating in an airtight container for up to three days. Reheat individual portions in the microwave or warm the whole dish in a 350°F oven until heated through. To make ahead, assemble the casserole without the cheddar topping, cover, and refrigerate for up to 24 hours; add cheese and bake when ready. For freezing, bake fully, cool, then wrap tightly and freeze for up to two months—thaw overnight in the fridge before reheating.

Final Thought

This low carb chicken casserole is a comforting, reliable dish that suits busy evenings and relaxed weekends alike. It pairs beautifully with a crisp green salad or simple roasted vegetables for a complete meal. With basic pantry spices and a handful of fresh florets, you’ll have a warm, cheesy dinner that feels like a hug on a plate.
