Steps

Before you start

Pat cod fillets completely dry with paper towels to help browning
Use fresh herbs for bright, vibrant flavor—dried herbs won't deliver the same punch
Prepare a shallow dish or gallon-size zip-top bag for marinating

1
Mix the marinade
- In a shallow dish or small bowl, whisk together the 1/4 cup olive oil, lemon juice, lemon zest, minced garlic, chopped parsley, thyme, salt, pepper, and red pepper flakes (if using).
- The mixture should be fragrant and well combined, with the herbs evenly distributed throughout.

Ready when: Marinade is fragrant and ingredients are evenly distributed
Tip: Don't skip the garlic—it's essential for flavor depth in a quick marinade
2
Coat the cod fillets
- Place the dried cod fillets skin-side up in the marinade dish.
- Spoon the marinade over each fillet, coating them generously on both sides and working it into all the crevices.
- If using a zip-top bag, place the fillets inside and pour in the marinade, then gently squeeze and massage the bag to coat evenly.

Ready when: Cod is completely and evenly coated with marinade
Tip: Use a shallow dish rather than a deep bowl—it allows the thin fillets to be coated on both sides
3
Marinate the fish
- Let the cod sit at room temperature in the marinade for exactly 20 minutes.
- Do not exceed 30 minutes, as the acidity of the lemon juice will begin to denature the delicate fish proteins and make the texture mushy.

Tip: Set a timer—overcooking the fish in the acidic marinade ruins the tender texture
4
Heat the skillet and oilOven 375°F / 190°C
- Remove the cod from the marinade, allowing excess liquid to drip back into the dish.
- Reserve the remaining marinade to drizzle over the cooked fish if desired.
- Heat the remaining 1 tablespoon of olive oil in a large skillet (10–12 inches) over medium-high heat.
- The oil should shimmer and just begin to smoke before you add the fish (approximately 375°F / 190°C).

Ready when: Oil shimmers and barely smokes; a drop of water sizzles violently and immediately evaporates
Tip: A hot pan is crucial for crispy, golden skin; a cool pan will cause the fish to steam rather than sear
5
Sear the skin side
- Carefully place the cod fillets skin-side down in the hot skillet.
- Do not move them—let them cook undisturbed for 4–5 minutes.
- The skin will slowly turn from pale to deep golden and crisp, and the fillet will naturally release from the pan when it's ready.
- You should hear a gentle, steady sizzle throughout cooking.

Ready when: Skin is deep golden and crispy; fillet releases easily from the pan when gently nudged with the spatula
Tip: Resist the urge to move the fillets—moving them breaks the crispy crust and causes sticking to the pan
6
Flip and finish cooking
- Flip each fillet gently with a thin spatula, supporting it underneath so it doesn't break.
- Cook the second side for 2–3 minutes until the flesh is completely opaque and flakes easily when prodded with a fork.
- Check the internal temperature with an instant-read thermometer inserted into the thickest part—it should register 145°F (63°C).

Ready when: Flesh is opaque throughout, flakes easily with a fork, and internal temperature reaches 145°F (63°C)
Tip: The second side cooks much faster than the first—watch carefully to avoid overcooking the delicate flesh
7
Plate and serve
- Transfer the cod to a serving platter or individual plates.
- If desired, drizzle with the reserved raw marinade (which adds extra brightness and herbaceous flavor) or finish with a squeeze of fresh lemon.
- Serve immediately while the skin is still crispy.

Ready when: Fish is plated and ready to serve
Tip: Serving with the reserved marinade drizzled on top adds back the fresh, bright flavors and herbaceous notes

Tips

Budget hack: Cod is often the cheapest white fish at the market. Ask the fishmonger for trim or smaller fillets—they taste just as good and cost significantly less.
Make it a full meal: Serve alongside steamed or roasted vegetables (zucchini, green beans, asparagus, or broccoli) and a simple grain (rice, orzo, farro, or crusty bread).
Grill option: If grilling instead of pan-searing, preheat the grill to medium-high, lightly oil the grates, and grill the marinated cod skin-side up for 5–6 minutes total, carefully flipping once halfway through. Skip heating the second side to keep the skin intact.
Baking option: For a completely hands-off approach, transfer the marinated cod to a lightly oiled baking sheet and bake at 400°F (200°C) for 12–15 minutes until the internal temperature reaches 145°F (63°C). You won't get crispy skin this way, but the fish will be moist and delicious.

Make ahead

The marinade can be made up to 8 hours ahead. Cover and refrigerate in an airtight container. Add the cod and marinate at room temperature for 20 minutes immediately before cooking.

Storage & reheating

Room temperature: Cooked cod is best eaten immediately but can sit at room temperature for up to 1 hour. Refrigerator: Store leftover cooked cod in an airtight container for up to 2 days. Reheat gently in a 275°F (135°C) oven for 5 minutes, or serve cold. Freezer: Freeze cooked cod for up to 2 months. Thaw overnight in the refrigerator before reheating in a low oven.

Substitutions

large lemon → lime or white wine vinegar. Lime provides a sharper, more floral citrus note; use 3 tablespoons fresh lime juice. White wine vinegar (2 tablespoons) is more mellow but still brightens the fish. Both work beautifully with cod.
fresh thyme → fresh dill or oregano. Dill is brighter and fresher, especially good with lemon and fish. Oregano is more peppery and herbaceous. Use the same weight (4g / 2 tablespoons).
fresh flat-leaf parsley → cilantro or fresh chives. Cilantro brings a floral, earthy note and changes the flavor profile significantly. Chives are milder and more delicate. Use equal amounts by weight or volume.
cod fillets (6 oz / 170 g each) → halibut, sea bass, flounder, or sole. These white fish work similarly; adjust timing based on thickness. Thinner fillets (flounder, sole) cook in 2–3 minutes per side. Thicker halibut may take 4–5 minutes per side. All benefit from the same marinade.
