# What You'll Need:

02 - 8 ounces cremini or button mushrooms, sliced
03 - 1 small onion, finely chopped
04 - 2 cloves garlic, minced
05 - 2 tablespoons chopped fresh parsley
→ Dairy
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
→ Pantry
11 - 2 tablespoons olive oil
12 - 2 tablespoons all-purpose flour
13 - 1 teaspoon paprika
14 - 1 teaspoon salt
15 - 1/2 teaspoon black pepper
16 - 1/2 teaspoon dried thyme
→ Topping
17 - 3/4 cup panko breadcrumbs
18 - 1 tablespoon melted butter
# How to Make It:
01 - Preheat oven to 375°F. Lightly grease a 1.5-2 quart 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, approximately 3 minutes.
03 - Stir in sliced mushrooms and sauté until golden brown, about 5 minutes. Add minced garlic and cook for 1 additional minute until fragrant.
04 - Sprinkle flour evenly over vegetables, stirring constantly to coat. Cook for 1 minute to remove raw flour taste.
05 - Slowly pour in milk while whisking continuously to prevent lumps. Add sour cream, paprika, salt, pepper, and dried thyme. Simmer until sauce thickens, 2-3 minutes.
06 - Stir in shrimp and cook just until they begin to turn pink, about 2 minutes. Remove from heat immediately as they will finish cooking in the oven.
07 - Gently fold in mozzarella, half the Parmesan, and fresh parsley. Transfer mixture to prepared casserole dish, spreading evenly.
08 - In a small bowl, combine panko breadcrumbs, melted butter, and remaining Parmesan cheese until well blended.
09 - Sprinkle breadcrumb mixture evenly over casserole. Bake uncovered for 20-25 minutes until bubbly and golden brown on top.
10 - Let casserole rest for 5 minutes before serving to allow sauce to set. Garnish with additional fresh parsley if desired.
# Expert Hacks:
01 -
- The creamy sauce comes together faster than you'd expect, no fancy techniques required
- Shrimp and mushrooms were meant to be together, each making the other taste better
02 -
- Overcooking the shrimp in the skillet makes them rubbery, they really will finish in the oven
- The sauce thickens as it bakes, so don't worry if it seems slightly loose going into the dish
03 -
- Dry your shrimp thoroughly with paper towels before adding them to prevent watery sauce
- Room temperature sour cream blends into the sauce more smoothly without curdling
