Creating Chicken Bubble Biscuit Bake Casserole is a straightforward process. Follow these steps for delicious results:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Prepare the Filling: In a large bowl, combine the shredded chicken, cream of chicken soup, milk, mixed vegetables, onion powder, garlic powder, and black pepper. Mix well until all ingredients are combined.
3. Transfer to Casserole Dish: Pour the chicken mixture into a greased 9×13 inch casserole dish, spreading it evenly.
4. Cut Biscuit Dough: Open the can of biscuit dough and separate the biscuits. Cut each biscuit into quarters.
5. Top the Casserole: Arrange the biscuit quarters over the chicken mixture. Make sure to leave some gaps, as the biscuits will expand during baking.
6. Add Cheese: Sprinkle the shredded cheddar cheese evenly over the top of the biscuits.
7. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes or until the biscuits are golden brown and fully cooked.
8. Cool & Serve: Once out of the oven, let the casserole cool for a few minutes before serving. This will make it easier to dish out.

Following these steps allows you to create a fantastic Chicken Bubble Biscuit Bake Casserole that is enjoyable both to prepare and eat.
