Lemon Buttered Cod Fillets

Microwave cod gets a bad rap, but this lemon butter version delivers flaky, moist fish in under 15 minutes with almost no cleanup. The covered casserole traps steam, which gently poaches the fillets in melted butter and lemon juice while the lemon pepper and paprika build a light, bright seasoning layer on top.

The key to great microwave fish is not overcooking it. Check at the 10-minute mark. The fillets should flake easily with a fork and look opaque all the way through. If the thickest part still looks translucent, give it another minute. That 2-minute standing time after cooking finishes the job with carryover heat, so pull it out a touch before it looks fully done.

Dot the butter in small pieces across the top rather than one big lump. This gives you even melting and coats each fillet instead of pooling in one spot.

Chef Tips

• Pat the cod fillets dry before arranging them in the dish for better seasoning adhesion
• Place thicker fillets toward the outside edge of the dish where microwave energy is strongest
• Use fresh lemon juice over bottled for a cleaner, brighter flavor
• Vent the plastic wrap by leaving one corner open to prevent steam buildup from popping the cover off

Variations

• Swap cod for haddock, tilapia, or any mild white fish
• Add a tablespoon of capers and a pinch of dill for a Mediterranean twist
• Top with seasoned breadcrumbs during the standing time for a crunchy contrast
