Ingredients Needed for Louisiana Casserole

The ingredients needed to make this Louisiana casserole recipe are classic cajun ingredients that come together for major flavor and texture. This meal is similar to a traditional jambalaya, but everything is cooked together in one dish. It’s savory and hearty, with warm spices that make this casserole irresistible. Check out the recipe card at the bottom of the post for exact measurements.

• Shrimp: For convenience, buy your shrimp peeled and deveined.
• Andouille Sausage: A smoked sausage commonly used in Cajun cuisine.
• Cooked Rice: I used minute rice for this recipe, but you can make regular rice with a rice maker.
• Yellow Onion: Adds a sweet, savory flavor and a bit of texture.
• Red Bell Pepper: Gives the dish a beautiful color and a slightly sweet crunch.
• Green Bell Pepper: Provides a green color, which adds contrast, making the dish look appetizing and tastes amazing!
• Canned Fire Roasted Tomatoes: Adds the most delicious smoky flavor.
• Butter: Cooking the vegetables in butter adds a rich, deep flavor.
• Garlic: Freshly minced garlic is one of the best ingredients to pair with shrimp (just ask this brown butter spicy shrimp), and along with the other veggies, it adds depth and complexity.
• Salt and Pepper: To enhance all of the flavors.
• Cajun Seasoning: You can use a store-bought spice blend or try this homemade cajun seasoning.

Breadcrumb topping

• Parmesan Cheese: For sharp cheesy flavor.
• Bread Crumbs: Adds golden, crispy texture on top of the casserole.
• Salt and Pepper: For extra flavor.

How to Make Louisiana Casserole

Trust me when I say this is an easy recipe to follow. Most of the ingredients are ready to go! You just need to sauté the veggies, heat the sausage, and cook the shrimp, and dinner is served! The whole family will love this one. Here’s how everything comes together:

1. Prep: Preheat oven to 375 degrees Fahrenheit and spray a 9×13-inch baking dish with non-stick cooking spray.
2. Sauté Veggies: Heat the butter in a large skillet over medium-high heat. Then add the onion, red, and green pepper to the skillet and sauté until the vegetables become tender.
3. Sauté Sausage and Shrimp: Add the garlic, sausage, and shrimp to the skillet, season with salt and pepper, sauté until the shrimp are mostly pink.
4. Combine All Ingredients: Add the vegetables and meat to the baking dish along with the rice, tomatoes, and cajun seasoning. Stir everything together.
5. Mix the Topping: Mix the parmesan cheese, bread crumbs, salt, and pepper, in a small bowl. Then sprinkle the top of the casserole with this mixture.
6. Bake: Place the dish in the oven and bake for 20 minutes, until the top is golden brown and the rice has had time to soak in any excess juice.
7. Rest and Serve: Remove from the oven and allow the casserole to rest for a few minutes before serving. Enjoy!
