Creating Texas Tamale Pie Casserole is straightforward when you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Cook the Meat: In a large skillet, brown the ground beef or turkey over medium heat. Drain excess fat.
3. Add Vegetables: Stir in the chopped onion and minced garlic. Cook until the onion is soft, about 5 minutes.
4. Add Beans and Corn: Mix in the black beans, diced tomatoes (with juice), and corn. Stir until combined.
5. Season the Mixture: Add chili powder, cumin, salt, and pepper. Allow the mixture to simmer for about 5 minutes.
6. Prepare Cornbread Batter: In a separate bowl, prepare the cornbread mix according to package instructions.
7. Layer the Ingredients: Spread the meat mixture evenly in a greased baking dish. Pour the cornbread batter over the top and spread it out evenly.
8. Bake: Place the dish in the preheated oven and bake for about 30-35 minutes, or until the cornbread is golden brown and a toothpick inserted comes out clean.
9. Cool the Casserole: Once baked, remove from the oven and allow it to cool for about 10-15 minutes.
10. Add Toppings: Top with shredded cheese and allow it to melt. Finish with a dollop of sour cream and optional cilantro garnish before serving.
