Ingredients

4 cod fillets, about 6 oz each
kosher salt
freshly ground black pepper
¾ cupsour cream, full-fat preferred
¼ cupDijon mustard
3 tbspfresh dill, finely chopped
2 tbspred onion, finely minced
1 tbspdry white wine, such as Sauvignon Blanc
½ cupseasoned breadcrumbs, panko or regular

Instructions

Set your oven to 425°F. This high temperature will give you flaky fish with a beautifully golden top without overcooking the delicate cod.
Lightly butter or oil an 8x11 inch baking dish. This prevents sticking and makes cleanup much easier later.
If using frozen cod, thaw it completely first, then pat each fillet thoroughly dry with paper towels. Any excess moisture will dilute your sauce and prevent proper browning.
Place the cod fillets in your prepared baking dish, leaving space between each piece. Season both sides generously with salt and pepper — the fish needs this seasoning to really shine.
Whisk together the sour cream, Dijon mustard, chopped dill, minced red onion, and white wine until completely smooth. The wine adds brightness that balances the richness of the cream.
Spoon the creamy sauce evenly over each fillet, spreading it to the edges. Sprinkle the breadcrumbs over the top — they'll turn golden and crispy as the fish bakes.
Bake for 15-18 minutes, until the fish flakes easily when tested with a fork and the breadcrumbs are golden brown. The internal temperature should reach 145°F.
