In a large skillet, cook the diced onions and celery over medium heat until softened, about 5 minutes.
Add the shredded chicken, chicken broth, garlic powder, thyme, salt, and pepper. Stir to combine.
Bring the mixture to a simmer and cook for 5-7 minutes, or until the liquid has thickened slightly.
Remove from heat and set aside.
Step 2: Make the Cheese Mixture
In a medium saucepan, whisk together the heavy cream or half-and-half and flour until smooth.
Cook over medium heat, stirring constantly, until the mixture thickens and bubbles, about 2-3 minutes.
Remove from heat and stir in the shredded cheddar cheese and cayenne pepper (if using). Stir until the cheese is fully melted and the mixture is smooth.
Set aside.
Step 3: Assemble the Casserole
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish.
Tear the biscuits into bite-sized pieces and place them in the bottom of the prepared baking dish.
Pour the chicken filling evenly over the biscuits.
Spread the cheese mixture evenly over the chicken layer.
Sprinkle with additional shredded cheese if desired.
Step 4: Bake
Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbly.
Remove from the oven and let it rest for 5-10 minutes before serving.
Step 5: Garnish and Serve
Garnish with fresh parsley for added color and flavor.
Serve hot, either as a main dish or as a side.
Tips:
For extra flavor, you can sauté the onions and celery in butter before adding them to the chicken mixture.
If you prefer a spicier casserole, add a pinch of cayenne pepper to the cheese mixture.
You can also add other ingredients like bacon bits or mushrooms to the chicken filling for extra texture and flavor.
Enjoy your delicious cheesy chicken biscuit casserole! 😊
