How do I know when cod is done?
Cod is done when it flakes easily with a fork and turns opaque. If you use a thermometer, cook to 145°F in the thickest part. Fish has minimal carryover, so do not count on it climbing much after you pull it.
Can I use frozen cod?
Yes. Thaw it fully in the fridge, then pat it very dry. Extra moisture is the enemy of browning and the main reason fish turns out pale and steamy instead of crisp.
“Fresh” cod note: A lot of seafood-case cod is previously frozen. That is totally fine, just expect a little more surface moisture and give it extra drying time.
What if my cod starts to fall apart when I flip it?
That usually means it is not ready yet. Give it another 30 to 60 seconds. Fish releases from the pan when a good crust forms. Also, a thin fish spatula helps a lot.
Is this recipe actually healthy?
Cod is a lean protein, and the sauce stays light: olive oil, citrus, garlic, herbs, plus a small amount of butter for gloss and flavor. If you want it lighter, cut the butter in half or swap it for extra olive oil. For sodium, choose low-sodium broth and taste before adding extra salt, especially if you use capers.
Can I swap in another fish?
Absolutely. Try haddock, pollock, halibut, or even salmon. Just adjust cook time based on thickness. Thin fillets cook fast, thick ones need a little longer.
Skin on or skinless?
Either works. For skin-on cod, sear skin-side down first and leave it alone so it gets crisp. The sauce is great either way.
