Heat a large skillet over medium heat with a drizzle of olive oil. Add the cubed chicken and diced andouille sausage. Season generously with the Creole Trinity and Herb seasoning and Cajun seasoning. Cook until everything is browned and the chicken is fully cooked through.
Pour the Blue Runner Cajun Gumbo Base into the skillet and bring to a light boil. Stir in the softened cream cheese and cornstarch. Let everything simmer together until the cream cheese is fully melted and the sauce has thickened into a rich, creamy gumbo-style gravy.
If your dough requires pre-baking, do that first according to package or recipe directions.
Spread a thin, even layer of the gumbo gravy onto the crust. Don't overdo it — a thin layer prevents the crust from becoming soggy.
Sprinkle a layer of mozzarella over the sauce. Using a slotted spoon, scoop the chicken and sausage mixture from the skillet, leaving excess liquid behind, and spread evenly over the cheese layer.
Top with additional mozzarella and the thinly sliced andouille arranged across the surface like pepperoni.
Bake at 400°F for 8 to 10 minutes until the cheese is melted and bubbly and the edges are golden. Garnish with bay leaves if desired.
