How to Fillet and Cook Giant Red Rockfish (Step-by-Step, No BS Guide)

Red Rockfish is one of the most underrated fish on the West Coast—cheap, wild, firm, and absolutely perfect for frying, baking, or grilling. If you’ve got one whole and fresh, don’t waste it. It’s easier than you think to turn that spiny, big-eyed beauty into crispy golden fillets.

Here’s how to fillet it yourself, remove the skin (or leave it), and cook it simple and perfect in a pan. No chef hat required.

Step 1: Clean the Fish (Get Messy)

If you’ve got a whole fish, first thing—gut it. Here’s how:

Lay the fish flat.
Run your knife from the belly up to the gills, nice and smooth.
Pull out the guts (yes, with your hands).
Rinse out the cavity with cold water until it’s clean.

You’re halfway there. Rockfish aren’t tricky once you get into it.

Step 2: Head On or Off — Up to You

Some people chop off the head behind the gills before filleting. Others like it on for grip or roasting whole. Either way works, but for fillets, removing the head makes it easier to work around the bones.

Step 3: Fillet the Fish (Take Your Time)

Put the fish on its side.
Cut right behind the gill plate, down to the spine.
Turn your knife flat and cut along the backbone all the way to the tail.
Do the same on the other side.

You now have two fillets. They’ll look rough at first, but don’t worry—you can clean them up next.

Step 4: Skin On or Skin Off?

Skin On:

Leave it. It crisps up nicely when pan-fried, especially if you press it down in a hot pan with a little oil or butter.

Skin Off:

Want clean white fish without the skin? Here’s how to remove it:

Lay the fillet skin-side down.
Start at the tail end and slip your knife between the meat and skin.
Keep the knife blade flat and pull the skin tight with your other hand.
Work the knife gently across.

Done right, the skin peels off in one piece.

Step 5: Trim It Up

Cut off any rib bones or belly flaps.
Feel for pin bones with your fingers and pull them with tweezers.

Now you’ve got clean, boneless fillets ready to go.

How to Cook Red Rockfish (My Way)

Forget the fancy stuff. Here’s my favorite way to cook red rockfish, and it never fails:

Pan-Fried Rockfish with Butter, Salt & Pepper

Heat a frying pan (cast iron if possible).
Add a big spoon of butter.
Season both sides of the fillet with salt and black pepper.
When the butter’s hot and foamy, lay the fish in the pan skin-side down if you kept the skin.
Let it cook 2–3 minutes per side, until it flakes with a fork and gets that golden brown crust.

That’s it. Serve with lemon or keep it plain. It’s killer either way.

Types of Rockfish You Can Buy or Cook

Red rockfish isn’t just one fish. There are dozens of rockfish species out there, and most cook up beautifully the same way.

Here are a few you’ll find online or at seafood markets:

🎣 Pacific Rockfish – The most common and affordable variety, often labeled simply as “Rockfish”
🐟 Kinki (Idiot Fish) – Bright red, super fatty, and amazing when broiled — try Kinki Rockfish for a Japanese-style twist
🐠 Yellowtail Snapper – Technically not a rockfish, but similar cooking style — Brazilian Yellowtail Snapper is buttery and flaky
🐟 Classic Snapper – Another firm white fish cousin — snapper fillets are great for baking or fish tacos
🐟 Assorted Rockfish – Shop all rockfish varieties here for different cuts, sizes, and fillets

Whether you're cooking whole fish or ordering boneless fillets, rockfish is versatile, affordable, and always delicious.

Pro Tip: Don’t Live Near the Pacific? No Excuse

Rockfish is caught year-round off the Pacific Coast, and if you live in the region and don’t take advantage of that—you’re missing out. If you’re further inland? No worries.

FAQs About Filleting & Cooking Rockfish

1. Can I bake rockfish instead of frying it?

Absolutely. Just season with salt, pepper, olive oil, maybe a few herbs, and bake at 375°F for 12–15 minutes. It’s easy and great with veggies or rice.

2. Is rockfish safe to eat raw or as sushi?

Generally no. Rockfish should be fully cooked to be safe, unless it’s been properly frozen and handled by sushi-grade standards. Stick to frying, baking, or grilling.

3. What does rockfish taste like?

It’s mild and slightly sweet, not fishy at all. The texture is firm and flaky, kind of like a lean snapper or cod.

4. How do I store leftover fillets?

Wrap them tightly and refrigerate. Eat within 2 days or freeze them. Reheat gently or eat cold over salad.

5. What sides go best with rockfish?

Simple is best. Roasted potatoes, sautéed greens, lemon rice, or just a crusty loaf of bread and a beer. Don’t overthink it.

That’s a Wrap (and a Damn Good Meal)

If you’re looking for a no-hassle fish that tastes amazing and cooks up fast, rockfish is it. Whether you fillet it yourself or buy it ready to go, just keep it simple and let the fish do the talking.
