Step 2: Prepare the Chicken Mixture
In a large bowl, combine the cooked, shredded chicken with the cream of chicken soup, sour cream, and frozen vegetables. Stir in the garlic powder, onion powder, dried thyme (if using), and black pepper. Mix everything together until well combined.
Step 3: Assemble the Casserole
Spread the chicken and vegetable mixture evenly in the prepared baking dish. If you’re adding cheese, sprinkle half of the shredded cheddar cheese over the mixture for a cheesy layer.
Step 5: Brush with Butter
Drizzle the melted butter over the top of the biscuits to help them brown and get crispy. If you like, sprinkle the remaining cheddar cheese on top for an extra cheesy finish.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake for 30-35 minutes, or until the biscuits are golden brown and the chicken mixture is bubbly and hot. If the biscuits brown too quickly, you can cover the casserole loosely with aluminum foil and continue baking until the filling is fully heated through.
Tips for the Best Chicken Bubble Biscuit Bake Casserole
Use Rotisserie Chicken: For an even quicker meal, use store-bought rotisserie chicken. It’s already cooked and shredded, saving you time on prep.
Add Extra Veggies: Feel free to throw in additional vegetables like sautéed mushrooms, spinach, or even a bit of chopped broccoli to make the casserole heartier and more nutritious.
Swap the Biscuit Dough: If you’re looking for a lighter version, try using a lower-fat biscuit dough, or even make your own biscuits from scratch to control the ingredients. You can also use crescent roll dough for a flakier, buttery topping.
Cheese Lovers: For a cheesy twist, mix some shredded cheese into the chicken mixture before adding the biscuits. This makes the casserole even creamier and adds a rich, cheesy flavor throughout.
Make It Spicy: If you like a little heat, add some diced jalapeños, a pinch of cayenne pepper, or a few dashes of hot sauce to the chicken mixture.
Check for Doneness: To ensure the biscuits are fully cooked through, make sure they’re golden and not doughy in the center. If you’re unsure, you can use a toothpick to test one of the biscuit pieces.
Make Ahead: You can prepare the casserole in advance. Assemble the casserole (without baking), cover it tightly with foil, and refrigerate it for up to 24 hours. When ready to bake, just pop it in the oven as directed.
