| Very cold unsalted butter, cubed | 80 g / 5½ tbsp |

Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 200°C / 400°F.
Lightly grease a rectangular baking dish, approximately 22 × 33 cm (9 × 13 inches).
Set it aside while preparing the filling.
2. Cook the Vegetables
Melt the butter in a large skillet or saucepan over medium heat.
Add the chopped onion, diced carrots, and celery.
Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables begin to soften.
They do not need to be completely tender at this stage because they will continue cooking in the oven.
3. Make the Creamy Sauce
Sprinkle the flour over the vegetables.
Stir continuously for about 1 minute to cook the flour and coat the vegetables.
Gradually pour in the chicken broth while whisking.
Add the milk or cream and continue whisking until the mixture is smooth.
Bring the sauce to a gentle simmer and cook for several minutes, stirring frequently, until it thickens enough to coat the back of a spoon.
4. Add the Chicken and Peas
Stir the shredded cooked chicken and frozen peas into the creamy sauce.
Season with salt, black pepper, and a pinch of garlic powder.
Taste and adjust the seasoning if necessary.
Transfer the hot chicken mixture to the prepared baking dish and spread it into an even layer.
5. Prepare the Cheddar Biscuit Dough
In a large bowl, combine the flour, baking powder, and salt.
Add the very cold cubed butter.
Using your fingertips or a pastry cutter, work the butter into the flour until the mixture resembles coarse crumbs.
Add the milk or buttermilk and approximately half of the shredded cheddar cheese.
Gently stir with a spatula until a thick, slightly sticky dough forms.
Do not overmix the dough, as overmixing can make the biscuits dense.
6. Add the Biscuit Topping
Using a spoon, drop portions of the biscuit dough evenly over the hot chicken filling.
You do not need to completely cover every part of the surface. Leaving small spaces between the biscuits allows steam to escape while the topping becomes beautifully golden.
Sprinkle the remaining cheddar cheese over the biscuits.
7. Bake
Place the casserole in the preheated oven.
Bake for approximately 20–25 minutes, or until the chicken filling is bubbling around the edges and the biscuit topping has risen and become golden brown.
The center of the biscuit topping should be fully cooked rather than wet or doughy.
If the biscuits brown too quickly, loosely cover the casserole with aluminum foil for the remaining baking time.
8. Rest and Garnish
Remove the casserole from the oven and allow it to rest for 5–10 minutes.
Sprinkle generously with freshly chopped parsley.
Serve warm.
Best Tips
Use fully cooked shredded chicken to keep the preparation quick and easy. Leftover roasted or poached chicken works particularly well.
Keep the butter very cold when making the biscuit dough. Cold butter helps create a tender, flaky texture as the biscuits bake.
Do not overmix the biscuit dough. Stop stirring as soon as the ingredients are combined.
Make sure the creamy chicken filling is thick before transferring it to the baking dish. A sauce that is too thin can make the biscuit topping soggy.
Let the casserole rest briefly after baking. The filling will thicken slightly, making it easier to serve.
Best Ingredient Options
For the chicken, cooked chicken breast provides a lean and mild flavor, while cooked chicken thighs can create a richer and more tender filling.
Whole milk gives the sauce a creamy texture, while heavy cream makes it richer. Buttermilk works particularly well in the biscuit topping because it adds a slight tang.
Sharp cheddar provides a stronger cheese flavor, while mild cheddar creates a softer, creamier taste.
You can use homemade chicken broth or a good-quality store-bought broth depending on what you have available.
Recipe Variations
Add mushrooms to the vegetable mixture for extra savory flavor.
For more vegetables, add diced potatoes, corn, green beans, or chopped broccoli.
For a stronger garlic flavor, add one minced garlic clove to the vegetables while they cook.
You can also add dried thyme, rosemary, or a small amount of poultry seasoning to the creamy chicken filling.
For an extra-cheesy casserole, add a little mozzarella along with the cheddar.
What to Serve With
This casserole is already a complete and hearty meal, but a simple green salad makes a fresh side dish.
Steamed green beans or roasted vegetables also pair beautifully with the creamy chicken filling.
For a larger family meal, serve it with a light vegetable soup or a simple cucumber salad.
Make-Ahead Instructions
The creamy chicken filling can be prepared up to 1 day in advance.
Allow the filling to cool, cover it, and refrigerate it.
Prepare the biscuit dough separately and keep it covered in the refrigerator.
When ready to bake, assemble the casserole and add the biscuit topping just before placing it in the oven.
Because the filling will be cold, you may need to add several extra minutes to the baking time.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
For food safety and best quality, keep the casserole refrigerated rather than leaving it at room temperature for an extended period.
Reheating
For individual portions, microwave for approximately 1–2 minutes, or until heated through.
For a larger portion, cover the casserole loosely with foil and reheat in a 175°C / 350°F oven until hot.
Remove the foil during the final few minutes to help the biscuit topping regain some of its texture.
Freezing
The chicken filling can be frozen separately for up to approximately 2–3 months.
For the best biscuit texture, prepare fresh biscuit dough when you are ready to bake the casserole.
If freezing the fully assembled casserole, allow it to cool completely, wrap it tightly, and freeze.
Thaw overnight in the refrigerator before reheating and baking until thoroughly hot.
Common Mistakes to Avoid
Do not add too much liquid to the sauce. The filling should be creamy and thick enough to support the biscuit topping.
Avoid using warm butter for the biscuits. Cold butter is important for creating a better biscuit texture.
Do not overwork the biscuit dough because this can result in tough, dense biscuits.
Do not skip the resting period after baking. The filling will be extremely hot and loose immediately from the oven.
Make sure the biscuit topping is fully baked in the center before serving. A golden surface does not always mean the middle is completely cooked.
