Instructions

To Make The Cajun Shrimp Alfredo Casserole:

  • Heat oven to 350°F.
  • Season the shrimp on both sides with a few pinches of salt and pepper.  Heat 1 tablespoon olive oil (or melt butter) in a large sauté pan over medium-high heat.  Add the shrimp and sauté for 5 minutes, stirring and flipping occasionally, until the shrimp are pink and cooked through.  Transfer shrimp with a slotted spoon to a clean plate, and set aside.
  • Heat the remaining olive oil (or butter) in the sauté pan.  Add bell peppers and onion, and cook for 5 minutes, stirring occasionally.  Add in the okra and garlic, and cook for 3 more minutes, stirring occasionally.
  • Transfer the cooked shrimp, veggie mixture, rice and alfredo sauce to a large mixing bowl, and toss until evenly combined.  Pour the mixture into a 9 x 13-inch baking dish, and spread out evenly.
  • Bake uncovered for 15 minutes.  Remove from oven, and serve immediately, garnished with toppings (

To Make The Alfredo Sauce:

  • Heat olive oil (or melt butter) in a large sauté pan over medium-high heat. Add garlic and sauté one minute, stirring occasionally, until fragrant. Sprinkle with flour, and stir to combine. Sauté for an additional minute to cook the flour, stirring occasionally.
  • Slowly pour in the chicken broth, whisking to combine until smooth. Whisk in milk until combined, and bring the mixture to a simmer.  (Be careful not to let it boil.)  Reduce heat to medium-low, and cook for an additional minute until the sauce has thickened.  Then add in the Parmesan cheese, Old Bay, salt and pepper, and stir until the cheese melted.  Remove from heat and set aside.
