1-First Step: Preheat and Prepare the Dish Start by preheating your oven to 375 degrees Fahrenheit and spraying a 9×13-inch baking dish with non-stick cooking spray. This ensures your Louisiana Casserole bakes evenly and doesn’t stick, making cleanup easy. If you’re adapting for dietary needs, like a vegan version, use an oil spray instead of non-stick spray that might contain animal products.

2-Second Step: Sauté the Vegetables In a large skillet over medium-high heat, melt the 1/4 cup salted butter. Add the 1/2 minced yellow onion, 1 diced green bell pepper, and 1 diced red bell pepper, then sauté until they’re tender, about 5 minutes. This step builds the base flavors, and you can add extra veggies like celery if you want more crunch in your Louisiana Casserole. For a milder version, choose bell peppers without seeds for less heat.

3-Third Step: Add Proteins and Seasonings Once the veggies are soft, stir in the 2 minced cloves garlic, 14 ounces andouille sausage cut into 1/4-inch rounds, and 1 pound peeled and deveined shrimp. Season with 1 teaspoon salt and 1/2 teaspoon pepper, then cook until the shrimp turns mostly pink, which takes about 3-4 minutes. This is where the dish gets its heart, and if you’re substituting proteins, ensure they’re cooked through for safety.

4-Fourth Step: Combine and Transfer Transfer the mixture from the skillet to your prepared baking dish. Stir in the 3 cups cooked white or brown rice, 1 (14.5-ounce) can fire-roasted tomatoes, and 2 tablespoons Cajun seasoning until everything is well combined. This step makes the Louisiana Casserole cohesive and flavorful, absorbing all the juices. You can use brown rice for more fiber if you’re focusing on health, adapting to different preferences seamlessly.

5-Fifth Step: Prepare the Topping In a separate bowl, mix the breadcrumb topping: 1/2 cup grated parmesan cheese, 1/3 cup plain bread crumbs, 1/2 teaspoon salt, and 1/2 teaspoon pepper. Sprinkle this evenly over the casserole for that perfect crunch. If you’re going gluten-free, swap the bread crumbs now to keep things inclusive.

6-Final Step: Bake and Serve Bake the casserole for 20 minutes, or until the top is golden brown and the rice has absorbed the excess juices. Let it rest for a few minutes before serving to allow flavors to settle. Serve it hot, perhaps with a side of greens, and enjoy how this Louisiana Casserole brings everyone together at the table.
