Preheat your oven to 375°F (190°C) and lightly grease a 9×9-inch baking dish.
2. Sauté Shrimp and Aromatics
In a skillet, melt butter over medium heat.
Add garlic and onion; sauté until fragrant and translucent, about 3–4 minutes.
Stir in shrimp and cook just until pink, about 2-3 minutes. Remove from heat.
3. Prepare the Creamy Sauce
In a separate bowl, mix heavy cream, sour cream (or cream cheese), paprika, salt, and pepper until smooth.
Combine the shrimp mixture with the cream sauce.
4. Assemble the Casserole
Pour the shrimp and sauce into the prepared baking dish.
Sprinkle shredded cheddar and Parmesan cheese evenly on top.
Optional: Add breadcrumbs for a crunchy topping.
5. Bake
Bake in the preheated oven for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden.
6. Serve
Garnish with fresh parsley before serving.
Serve hot with rice, pasta, or crusty bread to soak up the creamy sauce.
