So, it’s an ideal dish to make and the perfect 30-minute meal for home cooks everywhere. Let’s dive in and make this baked rockfish aka the perfect main course!

FAQ for Baked Rockfish Fillets

If you’re looking for substitutes for this recipe, let’s take a look. Don’t have butter? You can substitute olive oil. Make sure it’s extra virgin olive oil, however. You could also do a combination of butter and olive oil if you wish! Be sure to not over-do it though, if you do use olive oil, as you don’t want the sauce to be too thinned out.

Rockfish is a mild fish that will flake easily when baked. If you find that you can’t find rockfish fillets where you live then you can also substitute rock cod, black cod, pacific snapper, red snapper, or halibut. Halibut would be my last choice for this, and really if you can buy rockfish fillets, then do so! In my opinion, it really is the best fish.

This baked rockfish recipe does not have lemon in it. If you’re obsessed with lemon and want that extra flavor, then add the lemon zest of one lemon. You could also line the fish with lemon slices if you wish. However, I would avoid lemon juice.

Is Rockfish Hard to Cook?

Fish recipes can be intimidating if you don’t cook them often. However, it becomes easy the more you practice! This is a tasty first recipe to try your cooking skills on, so, the best tip I can give you is to purchase a thermometer so that you can check the internal temperature of the fish fillets if you’re worried they may not be fully cooked inside. The temperature you’re looking for is 145°F.

Rockfish fillets tend to be more expensive and therefore you may be worried about how to cook them. This recipe is foolproof and will yield delicious results! So long as you follow the instructions, and bake them accordingly, the fillets will be a 10/10 and you’ll be adding this to your regular list of recipes!

What Should I Serve with This Rockfish Recipe?

You can serve it with rice, potatoes, and or salad. If you do decide to serve it with rice, I’d save a bit of the sauce as a leftover, and pour it over the rice before placing the rockfish on top. The rice will feel a bit less bland and/or dry that way. We love to serve it with these roast potatoes! They’re delicious and one of our favorite recipes! Plus if you make the potatoes, you can bake them at the same time as the fish. A win-win.
