Creating this Cajun shrimp alfredo casserole is a fun, straightforward process that turns fresh ingredients into a cozy meal. We’ll walk through each step to ensure your dish comes out just right, with tips for timing and adaptations along the way. Start by gathering your tools and ingredients for smooth sailing.

First Step: Season and Cook the Shrimp

Begin by lightly seasoning the 2 lb of raw large shrimp with kosher salt and freshly cracked black pepper. Heat 1 Tbsp of extra-virgin olive oil in a large skillet over medium heat, then add the shrimp and sauté for 2-3 minutes per side until they turn pink and opaque. Once done, remove the shrimp from the pan and set them aside to rest, preventing them from overcooking later.

Second Step: Sauté the Vegetables

In the same skillet, add the remaining 1 Tbsp of olive oil. Toss in the thinly sliced bell peppers and red onion, cooking for about 5 minutes until they start to soften. Next, stir in the 2 cups of sliced okra and the 2 minced garlic cloves, sautéing for another 3 minutes until the veggies are tender-crisp. This step builds flavor and adds nutritious elements to your Cajun shrimp pasta bake.

Third Step: Make the Alfredo Sauce

In a separate saucepan, melt 1 Tbsp of olive oil or butter over medium heat. Add the 4 pressed garlic cloves and cook for 1 minute, stirring to release their aroma. Whisk in the 3 Tbsp of all-purpose flour and cook for another minute to form a roux, then gradually add 1 cup of chicken or vegetable stock followed by 1 cup of 2% milk, stirring continuously to avoid lumps.

Simmer the mixture for 2-3 minutes until it thickens nicely. For dietary tweaks, use non-dairy milk here if needed. Stir in the 3/4 cup of grated Parmesan cheese, 1 Tbsp of Old Bay seasoning, 1/4 tsp of kosher salt, and freshly ground black pepper to taste. Remove from heat once combined, creating a creamy base for this easy Cajun shrimp casserole.

Fourth Step: Combine and Assemble the Casserole

In a large mixing bowl, combine the cooked shrimp, sautéed vegetables, 5 cups of cooked rice, and the prepared Alfredo sauce. Toss everything together until evenly coated, ensuring the flavors meld well. Transfer the mixture to a greased baking dish, spreading it out evenly for consistent baking.

Final Step: Finish and Serve

Sprinkle extra grated Parmesan on top if desired, then bake the casserole at 350°F for 15 minutes until the surface is lightly golden and heated through. Serve hot, garnished with fresh lemon wedges and chopped fresh parsley for a burst of freshness. This quick Cajun shrimp alfredo casserole dinner serves 8 and reheats well, making it great for meal prep or busy families.

For instance, replace the 2 lb of shrimp with chicken breast strips for a heartier option that’s still quick to cook. Tofu cubes work well for vegans, providing a similar texture while keeping the dish light and protein-packed.

Fish like cod can substitute for a seafood twist, or even plant-based crumbles for those on a low-carb plan. These changes maintain the core of this creamy Cajun shrimp alfredo casserole while catering to different tastes and dietary needs.

Vegetable, Sauce, and Seasoning Modifications

Feel free to mix up the veggies in this recipe based on what’s in season or what you have on hand. Swap the bell peppers and okra for zucchini or spinach to add more greens without losing the colorful appeal of this spicy shrimp casserole. For the sauce, use coconut milk instead of regular milk to create a dairy-free version that’s still rich and creamy.
