An easy and healthy dinner is ready in minutes with this baked fish!

Hey, guys! I’ve got a great family-friendly dinner for you today…and it’s about as easy as it gets!

We love seafood, but sometimes my go-to salmon or shrimp just seems boring. In order to mix it up a bit I like to occasionally add some white fish into our meal plan.

I’ve found some great frozen cod fillets at Costco recently, which makes it much easier to keep the lean protein on hand. After all, when you live in the middle of rural Virginia, it’s not so easy to get fresh, high-quality seafood at the last minute!

You only need 4 ingredients, one dish, and about 10 minutes to prepare a delicious baked fish seafood dinner!

Is baked fish good for you?

Yes, yes, yes! Baked fish is a quick-cooking and easy option for busy weeknight dinners. Cod is a good source of heart-healthy omega-3 fatty acids and is especially rich in lean protein and vitamin B-12.

Baked fish such as halibut or cod is a quick and healthy dinner idea!

How do you bake white fish?

As this recipe shows, you don’t need any fancy ingredients or special equipment for a delicious baked fish dish! I season the cod (or halibut) with just salt, pepper, fresh lemon juice, and fresh herbs. These flavors highlight the natural, delicate flavor of the fish rather than overpowering it completely.

The cod is baked in a casserole dish, along with the tomatoes,  in a 400-degree F oven for about 15-20 minutes (or until the fish flakes easily with a fork). That’s it!

I’m telling you…simple is BEST!

You only need 4 ingredients for this simple and healthy baked fish!

A good piece of cod or halibut is so mild and tender that even non-seafood lovers will typically enjoy it (I’m talking to YOU, kiddos!). If I pair the fish with a tomato basil sauce and serve it over pasta, my little guys are sure to devour this healthy dinner.

Plus, it’s fresh, it’s easy, and it’s FAST — making this dish a winner all-around! And if regular pasta isn’t your “thing,” this meal is also great served with some crusty bread to soak up the sauce, or paired with zucchini noodles (“zoodles”) for a light, low-carb option. Make it your own, and enjoy!
