Fork-in-the-Pan Good!

Rosefish is a prized fish here in the Florida Keys. When you see it at the fish market, pick up a few pounds and taste it for yourself. When you catch it fresh, you are in for a real treat.

The fillets are small. One fillet per person should be enough when serving the fish with sides. For a meal centered mostly around the fish, plan on two fillets per person.

Some people compare rosefish to lobster. To me, it tastes more like a cross between grouper and snapper. The flesh is firm, succulent, and slightly sweet.

You know how much I love fresh fish, and this was hands down one of the best fish we have eaten in a long time.

What Is Blackbelly Rosefish?

Blackbelly rosefish, often called rosies, is a deep-water fish that you will not often find at the fish market. It is usually caught as bycatch while fishermen are targeting larger deep-water fish.

Rosefish is caught along deep drop-offs from the Florida Keys up the East Coast, as well as across the Atlantic and into the Mediterranean.

It is a striking fish with bright red-orange skin and large yellow eyes. Rosies are related to rockfish and scorpionfish and cook in much the same way.

Once filleted, the flesh is snowy white, firm, and succulent, with a mild, slightly sweet flavor. Some people compare it to lobster, although I think it tastes more like grouper or snapper.

Its firm texture makes it especially good for pan-searing.

Serving and Sides

Serve blackbelly rosefish with simple sides such as steamed green beans, roasted asparagus, steamed broccoli and carrots, or steamed spinach.

For a more filling meal, add lemon asparagus rice, roasted baby potatoes, garlic mashed potatoes, or cauliflower rice.

Garlic bread, baked potatoes, or French fries are also good choices, especially with the garlic butter and lemon sauce.

Storage and Reheating

Store leftover fish in an airtight container in the refrigerator for up to 3 days.

To reheat, place the fish in a covered skillet over low heat with a small amount of butter or water. Heat gently for a few minutes, just until warmed through.

FAQ

What does blackbelly rosefish taste like?

Mild and slightly sweet, with firm white flesh and a succulent texture. Some people compare it to lobster. It's closer to snapper or grouper than to anything strong-tasting like mackerel.

What is the best way to cook rosefish?

Pan-searing, baking, or broiling. The fillets are thin, so they cook fast, often in two to three minutes per side in a hot pan.

Are rose fish good to eat?

Yes. Rosefish are very good to eat. The flesh is white, firm, succulent, and slightly sweet. Some people compare the texture to lobster. It is especially good for pan-frying, baking, or grilling.

Is rosefish the same as ocean perch?

No. They're related, but ocean perch is a different fish. Blackbelly rosefish is also sold simply as "rosefish" or "rosies."

Why is blackbelly rosefish hard to find?

Fishermen usually catch it alongside larger deep-water species rather than targeting it, so supply is irregular. When you see it at the market, buy it.
