Exact amounts are listed in the printable recipe card at the end, so don’t worry about jotting them down now. Let’s break it down.

Cod Fillets and Seasonings

Cod is a mild, flaky white fish that’s perfect for baking. It holds up well and soaks in all the flavor. You can swap it with haddock or tilapia if needed.

Olive oil helps the seasonings stick and keeps the fish moist. A light drizzle is all you need.

Salt and black pepper are your basic flavor builders. Use them to taste—don’t skip!

Garlic powder and onion powder give the fish a subtle savory depth without overpowering the lemon and dill.

Fresh Lemon and Dill

Lemon is the star here. We’re using thin slices to bake with the fish, plus zest and juice in the sauce for brightness.

Fresh dill brings a grassy, citrusy lift. It pairs beautifully with seafood and gives the dish its signature flavor. Dried dill works in a pinch—just use a bit less.

Creamy Lemon Dill Sauce Components

Butter and flour form a quick roux, thickening the sauce without feeling heavy.

Milk or half & half creates the creamy base. Go with half & half if you want a richer texture without going full-on indulgent.

Dijon mustard adds a subtle tang and depth. It’s one of those “secret flavor weapons” I always keep on hand.

Lemon juice and zest brighten everything up—don’t skip these!

Chopped fresh dill ties it all together with that unmistakable herby finish.

And of course, a little salt and pepper to taste. Just enough to balance the creamy lemon dill sauce and let the cod shine.

How to Make Baked Cod with Lemon Dill

Here comes the fun part—bringing this baked cod with lemon dill to life. Don’t worry, you won’t need a culinary cape. Just follow these easy steps, and you’ll have a light seafood meal on the table faster than it takes to scroll through your dinner delivery app. Let’s get cooking!

Step 1 – Prepare the Cod

First things first—preheat your oven to 400°F. While it warms up, pat your cod fillets dry with a paper towel. This helps them roast, not steam, so you get that perfect oven baked white fish texture.

Place the fillets in a lightly greased baking dish. Drizzle with olive oil, then sprinkle on the garlic powder, onion powder, salt, and pepper. Give them a gentle rub so every bite gets seasoned love.

Top each piece with a few thin lemon slices. That citrus will bake right into the fish, giving it such a fresh, zesty lift.

Step 2 – Bake Until Tender and Flaky

Slide the dish into the hot oven and bake for about 15–18 minutes. The magic number? When your cod flakes easily with a fork and looks opaque all the way through.

This is your classic easy baked fish recipe moment—no flipping, no fuss. Just let the oven do its thing while you whip up the sauce or sip something bubbly.

Step 3 – Make the Creamy Lemon Dill Sauce

While the fish bakes, melt butter in a small saucepan over medium heat. Stir in the flour to make a smooth, golden roux—this is your base for that dreamy creamy lemon dill sauce.

Slowly pour in the milk (or half & half if you’re feeling fancy), whisking constantly so it stays silky and lump-free. Let it simmer until it thickens slightly.

Now stir in the Dijon mustard, lemon juice, zest, and chopped dill. Season with a pinch of salt and pepper, and you’ve got yourself a sauce that could win hearts on its own.

Step 4 – Combine and Serve

Once your cod is perfectly baked, spoon that warm, velvety lemon-dill sauce right over the top. It’s like a cozy sweater for your fish—rich, bright, and full of flavor.

Sprinkle with extra fresh dill or a lemon wedge if you’re feeling a little extra. This weeknight fish recipe looks fancy, but tastes like comfort in every bite.

Tips for Success

• Pat the fish dry before baking for better texture.
• Don’t overbake—cod is done when it flakes easily.
• Use fresh lemon and dill for the brightest flavor.
• Stir the sauce gently to avoid lumps.
• Try half & half for a richer, but still light, sauce.

Equipment Needed

• Baking dish – I use a ceramic one, but any oven-safe skillet works too.
• Small saucepan – Perfect for making that dreamy creamy lemon dill sauce.
• Whisk – Essential for keeping the sauce silky and lump-free.
• Knife and cutting board – For slicing lemon and chopping fresh dill.
• Measuring spoons and cups – To keep everything balanced and just right.

Variations

• Use salmon or tilapia instead of cod – Both are great alternatives if cod’s not in your fridge. Salmon brings a richer taste, while tilapia keeps things light and flaky.
• Add capers for a briny twist – A spoonful of capers adds a salty pop that plays beautifully with the lemon and dill. It’s like a little Mediterranean vacation on your plate.
• Swap dairy milk with almond or oat milk for dairy-free – This makes the creamy lemon dill sauce totally plant-based and gentle on sensitive stomachs, without losing that silky texture.
• Add steamed vegetables on the side for a full meal – Think crisp green beans, buttery asparagus, or even roasted carrots. They soak up that sauce like a dream.
• Mix in a pinch of red pepper flakes for heat – If you like a little kick, this small tweak adds warmth without overpowering the delicate fish.

Serving Suggestions

• Serve with roasted asparagus or green beans – Their crisp bite pairs beautifully with the tender baked cod and soaks up the creamy lemon dill sauce.
• Pair with garlic mashed potatoes or rice pilaf – These cozy sides balance the tangy sauce and turn your light seafood meal into total comfort food.
• A crisp white wine like Sauvignon Blanc works well – Its zesty notes echo the lemon and dill, making each bite taste even brighter.
• Garnish with extra lemon slices and dill for elegance – A simple touch that makes your easy baked fish recipe look restaurant-ready.

Frequently Asked Questions (FAQs)

Q: Can I use frozen cod for this baked cod with lemon dill recipe?

A: Absolutely. I’ve done it more times than I can count! Just be sure to thaw the cod completely in the fridge or under cold water. Then, pat it dry really well before seasoning. This ensures your oven baked white fish cooks evenly and doesn’t turn out watery.

Q: What can I use instead of fresh dill?

A: If your herb drawer is looking a little sparse, don’t worry—dried dill works too. The flavor won’t be quite as vibrant, but it still gives that classic herby touch. Just remember to use half as much since dried herbs are more concentrated.

Q: How do I know when the cod is done baking?

A: Great question! You’ll know your baked cod with lemon dill is ready when it flakes easily with a fork and turns opaque all the way through. It usually takes about 15–18 minutes at 400°F. I always check the thickest part of the fillet just to be sure.

A: You bet it is! This light seafood meal is low in fat, high in lean protein, and full of bright, fresh ingredients. Plus, the creamy lemon dill sauce adds indulgence without going overboard. It’s my kind of balanced comfort food.

Q: Can I make the creamy lemon dill sauce ahead of time?

A: Yes, and I often do! You can whip up the sauce a day or two in advance and store it in the fridge. Just reheat it gently on the stove, stirring so it stays smooth. That’s one less thing to worry about on a busy night!
