Method

Heat 2 tbsp olive oil and the butter in a wide Dutch oven over medium-low heat. Add the sliced yellow onion with ½ tsp salt and stir to coat. Cook undisturbed for 10 minutes until softened and beginning to turn translucent.

Reduce heat to low. Continue cooking the onions 15-20 minutes more, stirring every 3-4 minutes, until deeply golden, jammy, and caramelized. Remove to a plate and set aside.

While onions cook, combine the flour, 1 tsp salt, and black pepper in a shallow bowl. Toss the cod cubes in the seasoned flour until evenly coated. Shake off any excess.

Increase heat to medium-high. Add the remaining 1 tbsp olive oil to the Dutch oven and let it shimmer. Add the coated cod pieces in a single layer — work in two batches if needed. Sear 2-3 minutes per side until the exterior is golden and the fish flakes easily at the thickest point. The internal temperature should reach 63°C. Transfer to a plate.

Return the caramelized onions to the pan over medium heat. Add the minced garlic and cook 1 minute until fragrant. Squeeze in the lemon juice, add the zest, and sprinkle in the cayenne. Stir to combine and warm through for 1 minute.

Nestle the seared cod bites into the onion-lemon mixture. Spoon the sauce generously over each piece. Remove from heat, scatter fresh parsley on top, and serve immediately — let everyone reach into the same bowl.

Safety & Storage

Cooking Temperature

Cod must reach 63°C internal temperature throughout before serving. Use a calibrated probe thermometer inserted into the thickest piece of fish to verify doneness.

Cross Contamination

Communal serving bowl presents cross-contamination risk. Provide separate serving utensils for each diner. Do not allow diners to double-dip or use personal utensils after tasting.

High Risk Population

Pregnant women, young children, elderly, and immunocompromised individuals are at higher risk from undercooked fish. Ensure 63°C internal temperature is achieved. Reheated leftovers must reach 74°C minimum.

Storage

Refrigerate leftovers within 2 hours of cooking at 4°C or below. Consume within 2 days. Store in airtight container separate from other foods.

Shelf Life

Cooked cod dish maintains quality for up to 2 days refrigerated. Do not leave at room temperature for more than 2 hours total.

Allergen Warning

This dish contains fish, wheat (gluten), and milk. Clearly communicate all allergens to guests before communal serving. Individuals with severe allergies should avoid shared-bowl service.

Handling

Pat cod cubes thoroughly dry before flour coating to ensure proper searing and reduce splattering risk. Work in batches when searing to avoid overcrowding and temperature drop.

Pro Tips

Technique

Do not rush the onions — this is not a dish for people in a hurry. Keep the heat low, stir them every few minutes, and let them transform into deep golden sweetness. That patience is what makes everything else taste extraordinary.

Substitution

If cod is not available at your market, firm white fish like halibut or sea bass work beautifully here — just adjust the cooking time slightly based on thickness.

From the chef

The secret to these cod bites is the onion — cooked slow on low heat for a full thirty minutes until it surrenders to sweetness and turns deep amber. The cod gets dredged in seasoned flour and seared in the same pot until golden, then nestled back into the onion with garlic, lemon juice and zest, and a good hit of cayenne for warmth. Everything finishes together in that one pan, the sauce clinging to each piece of fish. Scatter parsley over the top and put the bowl in the center of the table — this dish is meant to be shared.
