What is Rockfish?

Pacific Rockfish is a white-fleshed, mild-flavored fish with a delicate texture and a sweet and nutty taste. It’s also known as Alaskan rockfish, rock cod, red snapper, or Pacific red snapper and is a plentiful near-shore fish found on the west coast of North America. There are more than 70 types of rockfish, and they are part of the much larger fish genus of Sebass.

How to make Pan Seared Rockfish

The first step is to pat dry the rockfish with paper towels, then liberally season the fillets with sea salt and black pepper to taste.

*You can also season the rockfish filets with lemon pepper, cajun seasoning, or your favorite spices.

Next, prepare the seasoned flour by adding ½ teaspoon of salt and ¼ teaspoon of black pepper to all-purpose flour (or gluten-free flour) to a shallow bowl.

How to cook the rockfish fillets

*Preheat the oven to 250 degrees F. to use as a holding oven.

olive oil and butter in a large saute pan

Prepare the large skillet (or a large nonstick skillet) by placing it over medium-high heat with one tablespoon of butter and one tablespoon of olive oil (or your favorite cooking oil).

Once the butter has melted, turn the temperature down to medium heat. Make sure not to let the butter/oil mixture get brown before adding fish to the hot pan.

*If you have a cast iron skillet, you use that to pan-sear the fish, it will add amazing color to the rockfish.

Place the floured rockfish fillets in the hot skillet, cooking on the first side for 3-4 minutes. Don’t be tempted to turn it over too soon; you want that delicious crunch and golden brown color that comes from not moving the fillets around.

Turn the rockfish over and continue to saute for another 3-4 minutes. When the pan-seared rockfish is fully cooked, place it on a baking sheet and into the preheated 250-degree oven while you make the lemon caper sauce.

Pan searing is one of my favorite ways to prepare fish. It really brings out the natural flavor and can be done in minutes.

Can I pan-sear fish without using flour?

Yes, you can.
While flour is generally the first choice for pan-searing fish, you can use finely ground cornmeal instead. To create that crunchy exterior we love, dip the fish in milk or beaten eggs before dredging the fillets in cornmeal.
