Pin it This comforting casserole combines succulent shrimp with golden mushrooms in a rich, velvety sour cream sauce. The dish comes together in under an hour and feeds four people generously. A buttery panko-Parmesan crust adds irresistible crunch, while the creamy interior delivers satisfying flavors from paprika, thyme, and garlic.
The rainy Tuesday I first made this shrimp casserole, I was trying to use up ingredients from an over ambitious grocery run. Something about the way cream and mushrooms cozy up together in the oven just felt like the right kind of comfort.
My sister in law actually asked for the recipe before she even finished her plate. Now she makes it for her book club meetings and says they always ask for seconds.
Ingredients
- Large shrimp: Fresh or thawed works perfectly, just pat them really dry first
- Cremini mushrooms: They hold their texture better than white mushrooms and taste more earthy
- Sour cream: The secret ingredient that makes the sauce velvety without being too heavy
- Panko breadcrumbs: Create this ridiculously good crispy topping that stays crunchy even under the creamy sauce
- Paprika and thyme: This combo gives it a subtle warmth that makes people ask what spices you used
- Both mozzarella and Parmesan: Mozzarella melts into gooey perfection while Parmesan adds that salty punch
Instructions
- Preheat your oven:
- Get it to 190°C 375°F and butter your casserole dish so nothing sticks
- Soften the aromatics:
- Cook the onion in olive oil and butter until translucent, then add mushrooms until theyre golden and smell amazing
- Build the sauce:
- Sprinkle flour over everything, stir constantly, then slowly pour in milk while whisking like your life depends on it
- Add the creamy stuff:
- Stir in sour cream and all those spices, let it bubble until it thickens enough to coat a spoon
- Gentle with the shrimp:
- Fold them in just until they start turning pink, theyll finish cooking in the oven so dont overdo it
- The cheese moment:
- Mix in mozzarella, half the Parmesan, and parsley, then pour everything into your buttered dish
- That golden topping:
- Mix panko with melted butter and the rest of the Parmesan, sprinkle it over the top like youre decorating a cake
- Bake until bubbly:
- Twenty to twenty five minutes until its bubbling around the edges and the top is toasty brown
Pin it Last winter my neighbor brought over some of this after I had surgery, and honestly it was the best medicine. Food that cares about you tastes different somehow.
Making It Your Own
Sometimes I swap in Swiss cheese instead of mozzarella when I want something more sophisticated. A pinch of red pepper flakes in the sauce adds this gentle warmth that surprises people.
What To Serve With It
A sharp green salad with lemon vinaigrette cuts through the richness perfectly. Steamed rice works too if you want something more substantial.
Wine That Works
Sauvignon Blanc has enough acid to balance the cream, but a buttery Chardonnay feels like its meant to be there. Whatever you pick, make sure its well chilled.
- Buy shrimp that smell fresh, not fishy
- Dont skip the resting period before serving
- Leftovers reheat surprisingly well in the oven

Recipe FAQ
- → Can I use frozen shrimp?
-
Yes, thaw frozen shrimp completely and pat them dry before adding to the sauce. This prevents excess moisture from making the casserole watery.
- → How do I store leftovers?
-
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 160°C (325°F) until warmed through.
- → Can I make this ahead?
-
Assemble the casserole completely, cover tightly, and refrigerate for up to 24 hours before baking. Add 5-10 minutes to the baking time if baking cold from the refrigerator.
- → What cheese works best?
-
Mozzarella provides excellent melt, but Gruyère, Swiss, or Fontina add deeper, nuttier flavors. Feel free to mix cheeses for a more complex taste profile.
- → Can I use different mushrooms?
-
Crimini, button, or shiitake mushrooms all work beautifully. For meatier texture, try portobello mushrooms sliced thinly. Wild mushrooms add earthy depth.
- → Is this freezer-friendly?
-
Freeze the unbaked casserole tightly wrapped for up to 2 months. Thaw overnight in the refrigerator before baking as directed. Already baked leftovers freeze well too.
