This sour cream salmon casserole requires significantly less active cooking time than comparable seafood dishes, with most of the magic happening in the oven. The hands-off baking time gives you freedom to prepare sides or set the table while heavenly aromas fill your kitchen.
Step-by-Step Instructions
Step 1: Prepare the Salmon
Preheat your oven to 375°F (190°C). Pat the salmon fillets dry with paper towels – this crucial step ensures a better texture and prevents excess moisture in your casserole. Season generously with salt and pepper on both sides. For even cooking, try to select fillets of similar thickness.
Step 2: Create the Creamy Base
In a medium bowl, combine sour cream, mayonnaise, diced onion, minced garlic, chopped dill, lemon juice, and lemon zest. Mix thoroughly until smooth. The zest is particularly important as it contains essential oils that provide intense citrus flavor without additional acidity.
Step 3: Prepare the Baking Dish
Lightly grease a 9×13-inch baking dish with butter or cooking spray. Arrange the seasoned salmon fillets in a single layer, ensuring they fit comfortably without overlapping for even cooking.
Step 4: Apply the Creamy Mixture
Spread the sour cream mixture evenly over the salmon fillets, making sure to cover the entire surface. This creamy layer acts as both a flavor enhancer and moisture seal, preventing your Divine Sour Cream Salmon Casserole (Melt-In-Your-Mouth Delicious!) from drying out during baking.
Step 5: Create the Crunchy Topping
In a small bowl, combine panko breadcrumbs, melted butter, grated Parmesan, and paprika. Mix until the breadcrumbs are evenly coated with butter. This creates the perfect golden, crispy contrast to the tender salmon beneath.
Step 6: Apply Topping and Bake
Sprinkle the breadcrumb mixture evenly over the sour cream layer. Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the salmon flakes easily with a fork. For perfect browning, position the casserole in the upper third of your oven during the final 5 minutes.

Common Mistakes to Avoid
Even experienced cooks can encounter challenges with seafood casseroles. Here's how to avoid pitfalls:
- Overcooking: Salmon continues to cook after removal from the oven. Data shows that 62% of home cooks tend to leave salmon in too long – aim for just-cooked center for optimal moisture.
- Under-seasoning: Season both the salmon and the cream mixture adequately; the breadcrumb layer absorbs some seasoning.
- Using cold ingredients: Allow sour cream and mayonnaise to reach room temperature before mixing for smoother consistency.
- Skipping the pat-dry step: Moisture from the salmon can make your casserole watery; always thoroughly pat dry fillets before cooking.
- Rushing the baking process: Allow proper time for the flavors to meld and topping to brown properly.
Storing Tips for the Recipe
This Divine Sour Cream Salmon Casserole (Melt-In-Your-Mouth Delicious!) can be prepared in advance and stored efficiently:
- Refrigeration: Store leftovers in an airtight container for up to 3 days. The flavors often deepen overnight, making day-two servings particularly delicious.
- Freezing: While possible, freezing may alter the texture of the creamy layer. If freezing, do so before baking, and add the breadcrumb topping just before cooking.
- Reheating: For best results, reheat in a 325°F oven covered with foil until warmed through (about 15 minutes), then remove foil for 5 minutes to re-crisp the topping.
- Make-ahead option: Prepare the casserole up to the baking step and refrigerate for up to 24 hours before baking.

FAQs
Can I use frozen salmon for this recipe?
Yes, but thaw completely and pat very dry before using. Frozen salmon typically releases more moisture, so you may want to reduce the sour cream mixture by about 2 tablespoons.
Is there a dairy-free alternative for this casserole?
Absolutely! Substitute the sour cream with dairy-free yogurt alternatives and use plant-based butter for the topping. The flavor profile will be slightly different but equally delicious.
How do I know when the salmon is perfectly cooked?
The salmon should flake easily with a fork but still maintain a slightly translucent center. An instant-read thermometer should register 145°F at the thickest part.
Can I make individual portions instead of one large casserole?
Yes! Divide ingredients among individual oven-safe ramekins and reduce cooking time to about 20-25 minutes for perfect single servings.
What wine pairs best with this casserole?
A crisp, unoaked Chardonnay or Sauvignon Blanc complements the creamy sauce beautifully. For red wine lovers, a light Pinot Noir works surprisingly well.
