Step 1: Preheat the oven and prep the dish
Preheat the oven to 180°C (350°F) and grease a 23x33 cm (9x13 in) baking dish with butter or oil so the casserole releases cleanly once baked.
Step 2: Season the chicken
Pat the chicken breasts dry with kitchen paper, then season both sides generously with salt and black pepper so the seasoning has direct contact with the meat.
Step 3: Sear the chicken
Heat the olive oil in a large skillet over medium-high heat and cook the chicken for 6-7 minutes per side until golden and the internal temperature reaches 74°C (165°F).
Step 4: Rest and shred the chicken
Transfer the chicken to a plate and let it rest for 5 minutes so the juices redistribute, then shred it into bite-sized pieces using two forks.
Step 5: Sauté the onion and pepper
In the same skillet, add the diced onion and red pepper and cook over medium heat for 4-5 minutes, stirring occasionally, until softened and lightly golden at the edges.
Step 6: Add the garlic and spices
Stir in the minced garlic, smoked paprika and cumin and cook for 30 seconds until fragrant, taking care not to let the garlic scorch.
Step 7: Combine chicken with the vegetables
Return the shredded chicken to the skillet and toss everything together for 1-2 minutes so the meat picks up the spiced vegetable flavour, then remove from the heat to cool slightly.
Step 8: Mix the creamed corn base
In a large mixing bowl, combine the tin of creamed sweetcorn with the drained sweetcorn kernels and stir until evenly distributed.
Step 9: Stir in the sour cream
Add the sour cream to the corn mixture and stir until the base turns smooth and pale yellow with no visible streaks.
Step 10: Fold in half the cheese
Add 120 g (1 cup) of the shredded cheddar to the corn and sour cream mixture, folding it through so it will melt evenly once baked.
Step 11: Make the cornbread batter
In a separate bowl, prepare the cornbread mix according to the packet instructions using the specified egg, milk and melted butter, whisking just until the lumps disappear.
Step 12: Layer the chicken mixture
Spread the chicken and vegetable mixture in an even layer across the base of the prepared baking dish, pressing gently to level it.
Step 13: Add the corn and cream layer
Pour the corn and sour cream mixture over the chicken layer and spread it evenly with a spatula so every corner is covered.
Step 14: Sprinkle the remaining cheese
Scatter the remaining 120 g (1 cup) of cheddar evenly over the corn layer so it forms a melted pocket beneath the cornbread topping.
Step 15: Pour over the cornbread batter
Spoon the cornbread batter over the cheese layer and spread it gently to the edges of the dish, taking care not to disturb the layers underneath.
Step 16: Smooth the top
Dip a spatula in water and run it lightly over the batter surface so it bakes into an even, level crust.
Step 17: Bake the casserole
Bake uncovered for 30-35 minutes at 180°C (350°F) until the cornbread top is golden and a toothpick inserted in the centre comes out clean.
Step 18: Check for doneness
The casserole is ready when the cornbread springs back lightly to the touch and the edges have pulled slightly away from the sides of the dish.
Step 19: Rest before slicing
Let the casserole stand for 10 minutes after baking so the layers set; this makes it far easier to cut clean portions.
Step 20: Garnish and serve
Scatter over the sliced spring onion, cut the casserole into 6 squares, and serve warm straight from the dish.
Pro Tips for the Best Chicken Cornbread Casserole
Shred the chicken while it is still warm; it pulls apart more easily and soaks up the seasoning better than chicken left to go cold. Do not overmix the cornbread batter once the wet and dry ingredients meet, as a few lumps keep the topping tender rather than dense or rubbery. If the top browns too quickly before the centre sets, tent the dish loosely with foil for the last 10 minutes of baking. Taste the corn and cream layer before assembling, since tinned creamed corn varies in sweetness and may need an extra pinch of salt or paprika to balance it.
Storage and Reheating
Cool the casserole completely, then cover the dish tightly with cling film or transfer portions to an airtight container and refrigerate for up to 4 days. To freeze, wrap individual squares in foil and freeze for up to 2 months; thaw overnight in the fridge before reheating. Reheat covered in a 160°C (325°F) oven for 15-20 minutes until warmed through, or microwave individual portions in 60-second bursts, checking as you go. Add a splash of milk or a knob of butter over the top before reheating to stop the cornbread layer from drying out.

Frequently Asked Questions
Yes, a shop-bought rotisserie chicken works well and saves the searing step entirely. Use around 500 g (roughly 3 cups) of shredded meat in place of the raw chicken breast. Warm it briefly with the sautéed onion, pepper and spices so it still picks up flavour before layering. This shortcut can cut about 15 minutes off the total prep time.
