Keto Chicken Casserole Supreme: Low-Carb Baked Chicken
Many cooks fail to let their chicken casserole keto bake set before slicing. This produces a runny sauce that pools at the bottom of the plate rather than clinging to the chicken. You end up with a disjointed meal instead of a cohesive bake.
This dish is a hearty blend of cooked chicken breast and chopped broccoli florets. A mixture of mayonnaise, sour cream, and Dijon mustard creates a rich base. It finishes with a layer of shredded cheddar, mozzarella, and parmesan that browns in the oven at 190°C (375°F).
The resting period decides the final texture. Let the casserole rest for 5 minutes after you remove it from the oven. This allows the cheese-curry sauce to firm up and the layers to set. Use a 22×28 cm oven-proof baking dish to ensure the heat distributes evenly across the surface.

Instructions
-
Prepare the oven
Preheat your oven to 190°C (375°F). Lightly grease a 22 × 28 cm oven-proof baking dish with a thin layer of butter. This prevents the cheese from sticking to the sides during baking.
-
Whisk the sauce
Combine the mayonnaise, sour cream, mustard, paprika, garlic powder, onion powder, salt and pepper in a large mixing bowl. Whisk the mixture until smooth. A consistent texture ensures the seasonings are distributed evenly.
-
Mix in ingredients
Add the diced chicken and chopped broccoli to the sauce. Stir until every piece is thoroughly coated. Proper coating prevents the chicken from drying out in the heat.
-
Layer the dish
Transfer the mixture into the prepared dish and spread it evenly. Sprinkle the shredded cheddar and mozzarella cheeses over the top. This creates a protective seal that keeps the contents moist.
-
Add final topping
Dot the surface with the melted butter. Sprinkle the grated parmesan cheese over the butter. The butter helps the parmesan caramelise into a golden crust.
-
Bake the casserole
Place the dish in the pre-heated oven and bake for 35 minutes. Look for the casserole to be bubbling and the cheese to be a deep golden brown. This colour indicates the flavours have concentrated.
-
Rest and serve
Remove the dish from the oven. Let the casserole rest for 5 minutes before serving. This allows the layers to set so the portions hold their shape on the plate.
Watch the cheese topping closely during the final minutes of baking. If the edges darken too quickly while the centre remains pale, the oven may be too hot. Rotate the dish or cover it loosely with foil to ensure the crust browns evenly without burning.
What goes wrong and why
The cheese topping can burn before the centre is bubbling. This happens if the oven temperature exceeds 190°C (375°F) or the dish is too shallow. Check the edges for a dark brown colour early on. Cover the top with foil to protect the crust while the middle heats through.
What to serve with it
Pair this dish with steamed cauliflower rice to maintain a low-carb profile. You may also serve it with a side of mixed salad greens dressed in lemon vinaigrette or sautéed spinach. These sides provide necessary vitamins and a fresh contrast to the rich, creamy cheese-curry sauce of the casserole.
Storing and reheating
Keep leftovers in a sealed container in the fridge for up to 4 days. Leave them uncovered for no more than 2 hours at room temperature. For longer storage, freeze the baked casserole in a sealed container for up to 2 weeks. Reheat in the oven until the centre is hot.
