Step 1
Preheat your oven to 350°F. In a mixing bowl, melt the butter then whisk it together with the mayonnaise, sour cream, and lemon juice until smooth. I find that using room temperature ingredients helps create a silkier sauce. Place the cod fillets in a baking dish and pour the sauce evenly over the top, making sure each piece is coated. Bake for about 30 minutes, or until the fish flakes easily with a fork. The sauce will bubble and turn lightly golden. Serve it straight from the oven with a spoonful of the creamy pan juices. It's that effortless.
Chef's Tip
For the best flavor, always use fresh lemon juice—it really brightens the dish. If your sauce starts to separate, a quick whisk will bring it back together.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave, adding a splash of water if the sauce thickens.
Variation Tips
For a different twist, try using salmon or halibut instead of cod—they both pair beautifully with this sauce. Sprinkle some capers or a pinch of red pepper flakes on top before baking for extra zing. This dish is lovely served over a bed of cauliflower rice or with a simple side of steamed asparagus.
