Kingklip is most similar to monkfish, grouper, and hake in both flavor and texture. It’s a mild, slightly sweet fish with dense, tender flesh that holds together well during cooking, making it comparable to any firm white fish that doesn’t fall apart on the grill or in a stew. If you’re trying to substitute kingklip in a recipe or wondering what to expect when you see it at a fish counter, these comparisons will get you close.
Flavor and Texture Profile
Kingklip has a mild, slightly sweet flavor with no strong “fishy” taste. The flesh is dense but tender, and it breaks into large, satisfying flakes when cooked. This combination of firmness and delicacy is what makes it prized in South African cuisine, where it’s one of the most popular restaurant fish. It belongs to the cusk-eel family and is endemic to southern African waters, which means most people outside that region have never encountered it fresh.
There are actually a few varieties. The more expensive red or golden kingklip has softer, more delicate meat. The cheaper black kingklip is firmer and not quite as tender, but still mild and versatile. If you’re buying frozen kingklip fillets abroad, you’re most likely getting the black variety.
The Closest Substitutes
The fish that behaves most like kingklip in the kitchen is monkfish. Both have firm, meaty flesh that resists flaking during cooking, both are mild and slightly sweet, and both can handle aggressive cooking methods without falling apart. Monkfish is sometimes called “poor man’s lobster” for its dense, almost shellfish-like texture, and kingklip shares that same satisfying chewiness.
Grouper is another strong match. One fishmonger, when asked to describe kingklip to an unfamiliar customer, simply said “it’s like a grouper.” That’s a reasonable shorthand. Both fish have thick, white fillets with a clean flavor and large flake, though kingklip tends to be slightly more tender than most grouper species.
Other solid substitutes, depending on what you’re cooking:
- Hake: The most natural swap if you’re in South Africa, where hake is abundant and sustainably fished. It’s milder and a bit softer than kingklip, so reduce your cooking time slightly.
- Cod: A good match for baked or poached preparations. Cod has a similar sweetness and large flake, though it’s less dense.
- Mahi-mahi: Works well for grilling. It’s firmer than kingklip and has a slightly stronger flavor, but the texture holds up the same way under high heat.
- Ling (pink ling): Actually a close relative of kingklip. In Australia and New Zealand, pink ling (Genypterus blacodes) is so similar that scientists have debated whether the two species are truly distinct.
How to Match the Substitute to the Recipe
Kingklip works across nearly every cooking method: grilling, poaching, baking, steaming, stewing, and smoking. That versatility is part of what makes it hard to replace with just one fish. The key is matching your substitute to what you’re actually making.
For grilling or pan-frying, you need a fish that won’t crumble when you flip it. Monkfish, mahi-mahi, and grouper all pass this test. Thinner, more delicate fish like sole or tilapia will not hold up the same way. For poaching or steaming, where the fish cooks gently in liquid, hake and cod work beautifully because their softer texture isn’t a liability. For stews and curries, any firm white fish will do, but monkfish is the best choice because it maintains its shape through long simmering.
If a recipe calls for kingklip specifically, the author likely chose it for its ability to stay intact while still being tender inside. Whatever you substitute, lean toward something firmer rather than flakier.
Nutritional Profile
Kingklip is an extremely lean fish. A 100-gram fillet contains just 76 calories, 19 grams of protein, and virtually no fat (0.08 grams). That puts it in the same nutritional category as cod, hake, and other lean white fish. It has essentially no carbohydrates.
By comparison, monkfish runs about 76 calories per 100 grams with slightly more fat, and grouper comes in around 92 calories. The differences are small enough that any of the substitutes listed above will give you a similar nutritional profile: high protein, very low fat, and minimal calories. If you’re swapping kingklip for something like salmon or mackerel, you’ll be getting a fattier, more calorie-dense fish with a completely different flavor.
Sourcing and Availability
Kingklip is primarily caught off the coasts of South Africa, Namibia, and southern South America. Outside those regions, it shows up mainly as frozen fillets in specialty seafood shops or international grocery stores. South Africa’s 2025 fisheries assessment rates the kingklip resource as “optimal,” a status that has held steady for the past decade, so it’s a reasonably sustainable choice when you can find it.
If you can’t find kingklip and want something both similar in taste and easy to source, hake and cod are your most accessible options in most Western supermarkets. For a closer texture match, look for monkfish or grouper at a fishmonger. Pink ling, if available in your area, is the closest genetic relative and the most faithful substitute overall.
