Cod cut into inch pieces, patted dry and seasoned with salt, garlic powder and pepper, then seared in olive oil until opaque and lightly browned on both sides.
The heat drops, butter and minced garlic join the pan for thirty seconds, and lemon juice finishes the fish gently, while a cold dip of Greek yogurt, mayonnaise, lemon zest, dill and parsley waits alongside.
Why This Recipe Works
- The cod is patted dry before it is seasoned. Wet fish steams instead of searing, and the light browning the recipe calls for depends on a dry surface hitting hot oil.
- The garlic goes into butter, not oil, and only for thirty seconds, after the heat has already dropped. Minced garlic in a still-hot searing pan burns in less time than that.
- Lemon juice is added last and off the higher heat, so it coats the cod gently rather than reducing hard and turning bitter against the butter.
- The dip is entirely no-cook — yogurt and mayonnaise both hold their texture cold, so it needs no chilling time and is ready whenever the fish is.
- Greek yogurt rather than sour cream alone. It gives the dip a thicker, tangier base that stands up to the richness of the garlic butter on the fish.
The Cod, In Three Short Stages
The fish itself takes barely ten minutes and moves through three distinct stages in the same pan, each one only a minute or two long.
Season
Cod patted dry and seasoned with salt, garlic powder and pepper before it goes anywhere near the pan.
SearOpaque through, lightly browned outside
Two to three minutes per side in hot olive oil, until opaque and lightly browned.
Butter and lemon30 seconds for the garlic, then off heat
Heat lowered, butter and minced garlic added for thirty seconds, then lemon juice stirred in to gently coat the cod.
How to Make It
Season the cod
Pat cod dry and season with salt, garlic powder, and pepper.
Sear
Heat olive oil in a large skillet over medium-high heat. Sear cod 2 to 3 minutes per side until opaque and lightly browned.
Finish in garlic butter
Lower heat. Add butter and minced garlic and cook 30 seconds, then add lemon juice and gently coat cod.
Mix the dip
Stir yogurt, mayonnaise, lemon zest, dill, and parsley together.
Serve
Serve cod bites immediately with chilled lemon herb dip.
Ingredient Notes
- Cod fillets, cut into 1-inch pieces
- A pound and a half, cut into even pieces so every bite gets the same two to three minutes a side.
- Plain Greek yogurt
- Half a cup, the base of the dip. Thicker than regular yogurt, it holds up alongside mayonnaise without thinning out.
- Unsalted butter
- Two tablespoons, added only after the initial sear, over lower heat — this is the finishing fat, not the searing one.
- Lemon zest and juice
- Zest goes into the cold dip, juice goes into the hot pan — the two forms of lemon doing two different jobs in the same recipe.
Success Tips
- Dry the cod thoroughly before seasoning it.
- Let the cod sear undisturbed for its full time per side.
- Drop the heat before the butter and garlic go in.
- Give the garlic thirty seconds and no longer before the lemon.
- Serve immediately — the dish is built to be eaten hot alongside a cold dip.
Serving Ideas
Serve immediately, hot cod bites next to the chilled dip, exactly as the recipe finishes. A squeeze of extra lemon at the table rounds it out.
Storage and Reheating
Refrigerate
Refrigerate cod and dip separately in airtight containers for up to 2 days.
Freeze
Not recommended. Cooked fish this delicate tends to dry out and change texture after freezing and reheating.
Reheat
Reheat gently in a skillet over low heat just until warmed through — high heat will toughen the fish. Serve with the dip cold, straight from the fridge.
Frequently Asked Questions
Can I use a different white fish?
Another firm white fish that holds its shape when cubed and seared would work the same way, though the two-to-three-minute-per-side timing is calibrated to cod's thickness and texture.
Can I make the dip ahead of time?
Yes — it is entirely no-cook and can be mixed hours ahead and refrigerated; if anything, chilling longer only helps the flavours settle.
My cod came out tough.
It was most likely left in the pan too long, either during the sear or the butter finish. Cod cooks quickly and firms up fast once it goes past opaque.
Why is there both garlic powder and fresh garlic?
They season two different stages: garlic powder is part of the dry seasoning on the raw fish, while the minced fresh garlic blooms in butter at the finish for a completely different, more immediate garlic flavour.
