This comforting baked dish combines plump shrimp with savory mushrooms in a velvety sour cream and milk sauce, accented with paprika, thyme, and Parmesan. The crunchy panko topping creates perfect texture contrast while everything bakes to golden perfection in under an hour.

The first time I made this shrimp mushroom casserole was on a rainy Tuesday when I needed something comforting but still elegant enough to feel like a treat. The way the kitchen filled with that incredible aroma of garlic, mushrooms, and simmering cream made me realize this would become a permanent fixture in my dinner rotation.

I served this at a small dinner party last winter and watched my normally reserved friend go back for thirds. That crispy buttery topping against the creamy shrimp filled center is the kind of texture contrast that makes people pause mid conversation.

Ingredients

  • Large shrimp: I buy them already peeled because my patience runs thin after work but fresh is always best
  • Cremini mushrooms: These give more earthy flavor than white buttons and hold up better in the oven
  • Sour cream: This is the secret ingredient that makes the sauce impossibly rich without being too heavy
  • Panko breadcrumbs: They create the most satisfying golden crust that stays crunchy even under the creamy layer
  • Paprika: Adds a subtle warmth and the most beautiful reddish hue to the sauce

Instructions

Get your oven ready:
Preheat to 375°F and butter your casserole dish while the oven heats so you are not scrambling later
Sauté the aromatics:
Cook the onion in olive oil and butter until translucent then add those mushrooms until they turn golden and smell incredible
Build the sauce base:
Sprinkle flour over the vegetables stir for a minute then pour in milk while whisking like your life depends on it
Add the creamy goodness:
Stir in sour cream and all those spices until everything is smooth and bubbling gently
Introduce the shrimp:
Fold them in just until they start turning pink because they will finish cooking in the oven and nobody likes rubbery shrimp
Assemble and top:
Pour everything into your dish then sprinkle that panko and butter mixture on top like you are tucking it in for a nap
Bake to perfection:
Let it go for about 25 minutes until the sauce is bubbling up through the golden crust

My mother-in-law asked for the recipe before she even finished her first serving. Now it is what she requests whenever she visits and I always make extra just in case.

Making It Your Own

Sometimes I swap half the mozzarella for gruyère when I want something fancier. The nutty flavor takes this from weeknight dinner to company worthy status without any extra effort.

What To Serve Alongside

A crisp green salad with vinaigrette cuts through the richness beautifully. I also love serving this with roasted asparagus or simple steamed green beans when I want something fresh.

Wine Pairing Wisdom

A chilled sauvignon blanc has enough acidity to stand up to the creamy sauce while complementing the sweetness of the shrimp. Chardonnay works too if you prefer something butterier.

  • Chill your wine glasses beforehand for the full restaurant experience
  • A light pinot grigio is perfect if you prefer something less oaky
  • Leftover wine can actually be added to the sauce for extra depth

Common Questions

Assemble everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. Add 5-10 minutes to baking time if baking cold from the refrigerator.

Swiss, Gruyère, or sharp cheddar create delicious variations. Each brings distinct depth while maintaining the creamy texture.

Thaw frozen shrimp completely and pat them dry before adding. Skip step 6 cooking time since frozen shrimp are already cooked, just fold them into the sauce.

A crisp green salad with vinaigrette cuts through the richness. Steamed rice, roasted asparagus, or crusty bread also complement beautifully.

The shrimp should turn pink and opaque. Since they continue cooking in the oven, remove them from the skillet when just beginning to turn color to prevent toughness.

Substitute the flour with a 1:1 gluten-free flour blend and use gluten-free breadcrumbs or crushed pork rinds for the topping.
