06 - 1/2 cup sour cream
07 - 1/2 cup whole milk
08 - 1/2 cup shredded mozzarella cheese
09 - 1/4 cup grated Parmesan cheese
10 - 2 tablespoons unsalted butter

# How-To Steps:
01 - Preheat the oven to 375°F. Lightly grease a medium casserole dish with butter or cooking spray.
02 - Heat olive oil and 1 tablespoon butter in a large skillet over medium heat. Add chopped onion and cook until softened, about 3 minutes.
03 - Stir in mushrooms and sauté until golden brown, approximately 5 minutes. Add minced garlic and cook for 1 additional minute.
04 - Sprinkle flour evenly over the vegetable mixture, stirring constantly to coat. Cook for 1 minute to remove raw flour taste.
05 - Gradually pour in milk while whisking continuously to prevent lumps. Add sour cream, paprika, salt, pepper, and thyme. Simmer until sauce thickens, 2-3 minutes.
06 - Stir in shrimp and cook until just beginning to turn pink, about 2 minutes. Remove from heat as they will finish cooking in the oven.
07 - Gently fold in mozzarella, half the Parmesan, and fresh parsley. Transfer mixture to the prepared casserole dish.
08 - In a small bowl, combine panko breadcrumbs, melted butter, and remaining Parmesan cheese. Mix until evenly distributed.
09 - Sprinkle breadcrumb mixture evenly over the casserole. Bake uncovered for 20-25 minutes until bubbling and golden brown on top.
10 - Let the casserole rest for 5 minutes before serving to allow flavors to settle. Garnish with additional fresh parsley if desired.
# Expert Tips:
01 -
- The creamy sauce comes together faster than you might think, perfect for those exhausting weeknights when you still want something special
- Everything bakes in one dish so cleanup is minimal and you can actually relax after dinner
02 -
- Overcooking the shrimp in the skillet makes them rubbery, so pull them the moment they start turning pink
- Letting the casserole rest for 5 minutes before serving helps the sauce set slightly so it does not run all over the plate
03 -
- Slice your mushrooms evenly so they all cook at the same rate and nobody gets a big raw chunk
- Grate your own Parmesan instead of using pre shredded for better melting and flavor
