Louisiana Casserole: From Prep to Plate

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This will ensure your casserole bakes evenly and thoroughly.
Step 2: Sauté the Aromatics
In a large skillet, melt the butter over medium heat. Add the minced onion, green bell pepper, red bell pepper, and garlic. Sauté until the vegetables are tender, about 5-7 minutes.
Step 3: Add the Sausage
Stir in the andouille sausage and cook for another 5 minutes until the sausage is browned and heated through. The aroma will be heavenly!
Step 4: Mix in the Shrimp
Add the shrimp to the skillet, along with the salt, pepper, and Cajun seasoning. Cook until the shrimp turns pink and opaque, about 3-4 minutes.
Step 5: Combine with Rice and Tomatoes
In a large mixing bowl, combine the cooked rice, the sautéed mixture from the skillet, and the fire-roasted tomatoes. Mix well to ensure everything is evenly coated.
Step 6: Prepare for Baking
Transfer the mixture into a greased casserole dish. Top with the parmesan cheese and sprinkle the bread crumbs evenly over the top. For added flavor, you can mix the bread crumbs with a little melted butter before sprinkling.
Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and bubbly. This is the moment where the magic happens!
Step 8: Serve and Enjoy
Once out of the oven, let the casserole sit for about 5 minutes before serving. This will help it set slightly and make for easier serving. Enjoy this Louisiana Casserole hot, and watch your family and friends devour it!
No-Store Runs Needed

Missteps & Fixes
