Garlic Butter Creamy Shrimp Casserole

Step 2: Sauté Aromatics

In a large skillet over medium heat, melt the butter. Add the chopped onion and cook for 2–3 minutes until soft and translucent. Then, add the minced garlic and sauté for another 30–45 seconds, making sure it doesn’t burn—garlic burns quickly and turns bitter.

Step 3: Cook the Shrimp

Add the seasoned shrimp to the skillet and cook for 2 minutes on each side until they turn pink and slightly opaque. Remove the shrimp from the skillet and set them aside.

Step 4: Make the Creamy Sauce

Reduce the heat to low and pour in the heavy cream, stirring gently. Add the cream cheese and stir until fully melted and smooth. For extra flavor, sprinkle in the paprika and red pepper flakes. Let the sauce simmer for 2–3 minutes, stirring constantly, until it thickens slightly. Taste and adjust salt and pepper.

Step 5: Assemble the Casserole

Preheat your oven to 375°F (190°C). In a baking dish, combine the cooked pasta or rice (if using) with the creamy sauce. Layer the shrimp on top, then sprinkle evenly with Parmesan and mozzarella cheese.

Step 6: Bake to Perfection

Bake uncovered in the preheated oven for 15–20 minutes, or until the cheese is melted, bubbly, and golden on top. Keep an eye on it—cheese can go from perfect to overdone quickly!

Step 7: Garnish and Serve

Remove from the oven and let it cool for a couple of minutes. Sprinkle freshly chopped parsley on top for a pop of color and freshness. Serve hot, either on its own or with a side salad or garlic bread.

Tips for the Best Garlic Butter Creamy Shrimp Casserole

1. Don’t overcook shrimp – They cook fast in the skillet and again in the oven, so slightly undercooking initially is ideal.
2. Cream cheese makes it extra silky – Soften it before adding to the pan to avoid lumps.
3. Customize the casserole – Add mushrooms, bell peppers, or spinach for extra texture and flavor.
4. Make ahead – You can assemble the casserole a few hours before baking and refrigerate; just add 5 extra minutes to the baking time.

This Garlic Butter Creamy Shrimp Casserole is rich, comforting, and full of flavor. The creamy sauce perfectly complements the shrimp, while the melted cheese on top adds that irresistible golden crust. Whether it’s a cozy weeknight meal or a dish for entertaining, this casserole is guaranteed to impress.

If you want, I can also make a shortcut version with just one pan, which is even faster and keeps all the creaminess intact. It’s perfect if you’re hungry and don’t want to deal with multiple dishes.
