One of my favorite things ever is showing you super simple staples for busy weeknight dinners. Like this lemon baked cod fish recipe. If you’re thinking that learning how to bake cod is complicated, it isn’t. Not only does the simple lemon and butter sauce impart major flavor, but this recipe for baked cod is ready in only 20 minutes.
I’m always looking for ways to incorporate more seafood into my meals and recipes, but we need to take care of a few misconceptions before we get to this easy baked cod recipe:
- “All seafood is super expensive.” Yes, it can be depending on what you’re making (lobster anyone?!), but here’s where ALDI makes things easy. They offer an impressive variety of fish and seafood that are high quality, but also affordable.
- “Seafood is boring.” Wrong! And you don’t need a crazy ingredient list to make it happen. The butter lemon sauce is the right amount of flavor and decadence, and it’s definitely not boring.
- “Seafood is complicated.” Wrong again. 🙂 My lemon baked cod recipe needs just 5 ingredients (plus salt and pepper) and is ready in less than 20 minutes, start to finish.
I’m always wary of pre-packaged foods, which is why I love the fish choices at ALDI. I don’t have to worry about preservatives or weird ingredients, and – bonus! – their cod fish is wild caught.
Plus, I’m a huge fan of the convenience of individually wrapped pieces of fish. The packaging prevents freezer burn, the fish tastes fresh, and you can easily scale my lemon baked cod recipe since they are separated into small portions.
If you’re looking to include more seafood in an affordable and fresh way, visit your nearest ALDI and grab some of this wild-caught cod. I know I can always count on high-quality at unbeatable prices when I go there.
How To Bake Cod In The Oven
There are many healthy recipes for cod baked in the oven, but I’d argue that this one is the best! Using just 5 ingredients plus salt and pepper, we’re making a flavorful baked cod with lemon and butter that adds major flavor.
Here’s how to bake cod with my favorite wild caught Alaskan cod from ALDI:
- Thaw your cod fillets. This isn’t absolutely required, but it’s easier to brush lemon butter onto cod if it’s thawed first. Since the pieces are not too thick, they thaw pretty quickly in a bowl of water.
- Pat dry. Remove the fillets from the packaging and pat dry with paper towels.
- Make lemon butter. Melt butter, and stir in lemon juice and lemon zest.
- Season cod. Arrange the cod fillets in a baking dish, then brush lemon butter over them. Season with garlic powder, sea salt, and pepper on both sides.
- Bake the cod fish. Cook until it’s opaque and flakes easily with a fork.
What Temp To Bake Cod?
What temperature should cod be cooked at? There are different options for cooking temperatures, but I like 400 degrees F because:
- Cooking at a higher heat means faster cooking and less chance of drying out.
- It’s a standard temperature and makes it easy to estimate cooking time, based on size.
TIP: The general rule of thumb is to cook fish for 10 minutes per inch of thickness. But, it can still vary, so check a couple minutes sooner than you’d need based on thickness alone.
How Long To Bake Cod At 400
This baked cod with butter sauce will take about 12-15 minutes in a 400 degree F oven. If your cod is frozen, read below!
How Do You Know When Cod Is Done?
Baked cod with lemon will be opaque and flake easily when it’s cooked through. It should reach an internal temperature of 145 degrees F.
How To Make Baked Cod From Frozen
I prefer to thaw my cod fillet before putting it in the oven, but if you forgot or don’t have time to let it thaw, you can also easily make this oven baked cod fillet right from frozen.
Follow the same directions as above, but add on 5-10 minutes of baking time. The exact time will vary a bit depending on the size of the fillet, but cook it until it’s cooked through, opaque, and flakes easily.
Is Lemon Baked Cod Healthy?
Yes! This lemon garlic baked cod is healthy!
Not only is it recommended to include seafood in your diet on a regular basis [*], but it’s a wholesome food that doesn’t need much to make it shine. It’s a great source of protein, as well as vitamins and minerals.
How To Store Baked Cod
Store this oven baked cod fish in the fridge for 2-3 days.
Reheat in a hot skillet or 350 degrees F oven for best results. I don’t recommend microwaving fish, but it will work if you must.
Can You Freeze This Recipe For Baked Cod?
Yes, you can freeze easy baked cod recipes like this one, simply let them cool completely. Then freeze for 3-4 months in an airtight, freezer-safe container.
However, since Fremont Fish Market cod from ALDI already comes frozen, and this lemon butter baked cod recipe takes just a few minutes to prep, there isn’t much advantage to freezing it after cooking. I much prefer to make it fresh!
What Goes With Baked Cod Fish?
What do you eat with cod? There are so many options! This baked cod with lemon and butter is seasoned simply, so it goes with just about anything.
- Fried Radishes – If you’re missing potatoes, you’ve got to try fried radishes. The texture and flavor is so similar.
- Kale and Brussels Sprout Salad – This hearty salad is packed with flavorful ingredients like bacon, cranberries, and pecans!
- Sauteed Broccoli Stir Fry – Broccoli is a natural side for lemon butter baked cod, don’t you think? This one’s ready in no time at all.
- Oven Roasted Brussels Sprouts – You CAN make frozen Brussels sprouts in the oven. No soggy sprouts here!
- 5-Ingredient Keto Bread – If a meal doesn’t feel complete without some bread, this is a nutritious choice… and perfect for sopping up extra lemon butter sauce.
For a different way to serve cod, try air fryer chili lime cod.

Tap on the times in the instructions below to start a kitchen timer while you cook.
Preheat the oven to 400 degrees F (204 degrees C). You can bake the cod fillets from frozen or thaw them first in a bowl of cold water. (I prefer thawing if you have time, as it makes it easier to brush on the butter without solidifying.)
Use paper towels to pat the cod fillets dry. Arrange them in a single layer in a 9x13 baking dish.
In a small bowl in the microwave or saucepan on the stove, melt the butter. Remove from heat. Stir in the lemon juice and lemon zest.
Brush the lemon butter over the cod fillets. Season with garlic powder, sea salt, and black pepper. Flip and repeat both lemon butter and seasoning on the other side.
Bake for 12-15 minutes (will vary by thickness), until the baked cod is opaque and flakes easily with a fork. Sprinkle with fresh parsley and serve.
