Equipment Needed
- 9×13-inch casserole dish
- Large mixing bowl
- Measuring cups and spoons
- Aluminum foil (optional)
- Oven mitts
- Serving spoon
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch casserole dish with cooking spray or a small amount of olive oil.
Cooking Intensity
Moderate-High Oven Heat
Preheating ensures even cooking and proper melting of the cheese.
Step 2: Prepare the Chicken Mixture
In a large mixing bowl, combine:
- Cooked chicken
- Pizza sauce
- Italian seasoning
- Garlic powder
- Onion powder
- Salt
- Black pepper
Mix thoroughly until the chicken is evenly coated.
The sauce should distribute evenly throughout the mixture.
Step 3: Assemble the Base Layer
Spread the chicken mixture evenly into the prepared casserole dish.
Press gently with a spoon to create a uniform layer.
This base serves as the “crust” of the casserole and holds all the delicious toppings.
Step 4: Add the Cheese Layer
Sprinkle:
- 1½ cups mozzarella cheese
- Parmesan cheese
evenly over the chicken layer.
Reserve the remaining mozzarella for the final topping.
Cooking Intensity
No Heat Required
This assembly step ensures every bite contains plenty of cheesy goodness.
Step 5: Add the Pizza Toppings
Arrange the toppings evenly across the cheese layer:
- Pepperoni slices
- Mushrooms
- Green bell peppers
- Black olives
- Onions
Feel free to customize with additional keto-friendly toppings such as:
- Cooked bacon
- Sausage
- Jalapeños
- Spinach
Step 6: Add the Final Cheese Layer
Sprinkle the remaining mozzarella cheese over the toppings.
The cheese creates a golden, bubbly finish once baked.
Step 7: Bake the Casserole
Place the casserole dish in the preheated oven.
Bake for 25–30 minutes.
Cooking Intensity
Moderate-High Heat (375°F / 190°C)
Bake until:
- Cheese is fully melted
- Edges are bubbling
- Top becomes lightly golden
If you prefer extra browning, broil for 2–3 minutes at the end.
Optional Broiling Intensity
High Direct Heat
Watch carefully to avoid burning.
Step 8: Rest Before Serving
Remove the casserole from the oven.
Allow it to rest for 10 minutes.
Resting Intensity
Room Temperature Resting
Resting allows the casserole to set, making it easier to serve neat portions.
Step 9: Garnish and Serve
Top with:
- Fresh basil
- Extra Parmesan cheese
- Crushed red pepper flakes
Serve warm and enjoy.
