• 1 teaspoon onion powder: adds subtle sweetness and complexity
• Zest from one lemon: brightens the whole dish with citrus oils
• 2 tablespoons freshly squeezed lemon juice: adds tang and freshness
• Quarter teaspoon red pepper flakes: for just a whisper of heat that contrasts nicely with the butter
• 1 tablespoon fresh parsley: chopped for color and a fresh herbal note to finish
• 1 lemon sliced: for layering on top to infuse flavor as it bakes

One of my favorite things about this recipe is the way the fresh lemon slices gently roast on top of the fish. It reminds me of lazy Sunday dinners with family where simple ingredients turn into something memorable. The buttery sauce infused with garlic and lemon zing keeps me craving it time and time again.

Adding a pinch of fresh dill or tarragon in warmer months or roasted root vegetables in cooler seasons can enhance the dish and add seasonal depth.

Serving Suggestions

Serve this cod alongside steamed asparagus or green beans and a light couscous or rice pilaf for a well-rounded meal. A crisp green salad dressed with lemon vinaigrette pairs beautifully to echo the citrus notes.

Creative Twists

You can swap cod for other flaky white fish like haddock or tilapia depending on availability. For a dairy-free option replace butter with olive oil but expect a different flavor profile.

Using freshly squeezed lemon juice and zest really makes a difference in giving the sauce a fresh lively flavor you will want to savor.
