Pan-Seared Cod with Mediterranean Veg
I used to glaze fish. Everything got a glaze. Honey-soy, maple-miso, teriyaki — I thought these things were what made fish taste good. They were, it turned out, what made fish taste like sugar. The actual fish was barely visible underneath.
When sugar and I parted company, the glazes went with it, and I discovered something I should have known all along: good cod doesn’t need sugar. It needs a hot pan, dry skin, olive oil, and a squeeze of lemon. The Mediterranean vegetables alongside do everything the glaze was doing, with none of the sugar.
Pat the fish completely dry before it touches the pan. This is the single most important step in getting a proper golden sear. Any moisture on the surface means steam, and steam means the fish sticks and falls apart. Dry fish = crisp fish.

Ingredients
Serves 2 · Scale as needed
- 2 x 150g cod fillets, skin-on
- 1 cup mixed bell peppers, sliced
- ½ cup courgette, sliced
- 1 tbsp ⇄ extra virgin olive oil ⇄ the swap base
- 1 tsp dried oregano
- 1 ⇄ lemon, for squeezing ⇄ the flavthe swap
- pinch sea salt and black pepper
Instructions
-
1
Heat olive oil in a wide skillet over medium-high heat. Add the peppers and courgette with a pinch of salt and cook for 5–6 minutes until tender-crisp and lightly charred.
-
2
Pat the cod fillets completely dry with kitchen paper. Season well with salt, pepper, and oregano on both sides.
⇄ Swap NoteWithout a sugary glaze to create colour, the Maillard reaction from a dry, hot sear does all the work. Dry the fish thoroughly — this step cannot be skipped.
-
3
Push the vegetables to the side of the pan and add the cod fillets skin-side down. Cook undisturbed for 3–4 minutes until the skin is golden and crisp.
-
4
Flip gently and cook for a further 2–3 minutes until the fish is just cooked through. Squeeze fresh lemon over everything and serve immediately.
Why I Made This Swap
Honey and maple-based fish glazes can add 10–14g of sugar to what is otherwise a naturally zero-sugar protein. Searing cod with extra virgin olive oil and roasted Mediterranean vegetables delivers complex flavour through the Maillard reaction and natural vegetable sweetness — with virtually no added sugar. Cod itself provides 34g of protein per serving with minimal fat.
Common Mistakes
- Not drying the fish. Wet fish steams instead of searing. Pat dry thoroughly — both sides — before the fish goes anywhere near a pan.
- Moving the fish too soon. Leave it alone. The fish will naturally release from the pan when it’s ready to flip. If it’s sticking, it needs more time.
- Overcooking. Cod is done when it flakes easily with a fork. Overcooked cod is dry and disappointing — check at 3 minutes and work from there.
Storage
Cod is best eaten immediately. If you have leftovers, flake them cold into a salad the next day — delicious with the Mediterranean Chickpea Salad. Don’t reheat fish in a microwave.

Frequently Asked Questions
Can I use frozen cod?
Yes — thaw fully in the fridge overnight and pat very dry before cooking. Frozen fish often has more moisture, so drying is even more important.
What other vegetables work?
Asparagus, cherry tomatoes, and fennel are all excellent with cod. Keep the cooking time similar.
What wine pairs with this?
A crisp dry white — Albariño, Vermentino, or a simple Pinot Grigio. The lemon and Mediterranean herbs need something equally bright.
