10 Cane Toads

Cane toads are a major pest in Australia, wreaking havoc on local wildlife. Some people have wondered if we could turn this invasive species into a meal. It sounds simple—catch a few, cook their legs, and help control their numbers. But before you fire up the grill, there are a few things you should know.

Cane toads are packed with potent toxins. These toxins aren’t just on their skin but can be found throughout their bodies, including in the back legs. Even if you manage to cook them and don’t feel any immediate effects, the risk is still there. The toxins can mess with your heart and cause long-term cell damage. It’s a gamble—and not one you want to take lightly.

While cane toads might seem like an endless supply of free protein, the risks of eating them are significant. With toxins that vary from one toad to another, the potential dangers are unpredictable. For now, the idea of eating cane toads remains a risky proposition, with the potential for serious health consequences.^[1]

9 Jellyfish

Jellyfish numbers are exploding in oceans worldwide, especially in the Mediterranean. With fewer predators like tuna and turtles around, jellyfish have taken over, disrupting marine ecosystems. Some creative minds, like marine biologist Professor Silvio Greco, have a unique idea: If we can’t get rid of them, why not eat them? At the Slow Fish festival in Genoa, Greco showed how to prepare jellyfish by boiling them in lemon juice and vinegar to neutralize their sting and then frying them in a light tempura batter.

The dish was a hit. Jellyfish might not have much flavor on their own, but their salty, sea-like taste and unique texture make them perfect for adventurous eaters. Rich in protein and low in calories, they could be a sustainable addition to our diets. With more chefs getting creative in the kitchen, jellyfish might just be the next big thing on the menu.^[2]

8 Asian Shore Crabs

Asian shore crabs have invaded the U.S. East Coast, showing up from Maine to Florida. These small, nickel-sized crabs have been causing big problems since the 1980s, outcompeting native species for food and disrupting local ecosystems. But Chef Bun Lai sees them as more than just a pest. At his restaurant, Miya’s Sushi in Connecticut, he turns these crabs into a tasty dish, frying them to a perfect crunch.

Harvesting these crabs is simple—they can be collected by hand from under rocks along the coast. Once you’ve gathered enough, pop them in the freezer to humanely kill them, then boil and fry them. A splash of lime juice and a sprinkle of seasoning bring out their natural flavors, making them a savory snack you can enjoy like popcorn.

By eating Asian shore crabs, we can help control their population and give our taste buds something new to enjoy. It’s a creative way to tackle an invasive species and enjoy a delicious, sustainable treat.^[3]

7 Nutria (Swamp Rat)

Nutria, those big, orange-toothed rodents, are wreaking havoc in Louisiana’s wetlands. Initially brought in for the fur trade, they’ve overrun the area, eating the plants that keep the swamps intact. As their population explodes, so does the damage. But instead of just trying to eliminate them, some people are finding a tastier solution: putting them on the menu.

Chefs like Philippe Parola are turning nutria into a sustainable delicacy. The meat, which tastes like dark turkey, is being cooked up in all sorts of dishes. Nutria could be the next big thing in eco-friendly eating—helping control the population while providing a healthy, lean protein. It’s an effective way to reduce the nutria population, positively impacting the environment and serving up something new and delicious at the same time.^[4]

6 European Green Crabs

European green crabs are taking over the shores of Washington State, eating their way through marshes and bays. These little crabs have a big appetite for native species, including young Dungeness crabs and eelgrass. They might be edible, but that doesn’t mean they’re easy to turn into a meal. Their small size and less-than-stellar taste compared to other local crabs make them a hard sell for most seafood enthusiasts.

Some have suggested eating these invasive crabs to help control their numbers. However, it’s not so simple. The crabs often live in shallow, muddy areas that are hard to reach. Plus, people might accidentally catch native crabs instead, making this idea tricky to execute. Even if we could catch enough, over-harvesting them might lead to unintended consequences, like population booms when younger crabs are left unchecked.

Still, finding ways to cook and enjoy green crabs could be a creative solution. While it’s a tough task, it’s worth exploring. For now, these crabs remain a crunchy challenge on our coasts and in our kitchens.^[5]

5 Green Iguanas

South Florida is crawling with green iguanas, but to some, these invaders are more than just a nuisance—they’re dinner. Known as “pollo de los árboles,” or chicken of the trees, iguanas are a popular dish in the Caribbean. Their meat is lean and high in protein, and some even believe it has medicinal properties. In places like Fort Lauderdale, locals like Ishmeal Asson have turned iguana hunting into a culinary tradition, roasting them over open flames and seasoning them with curry and hot peppers.

Preparing an iguana is easier than you might think. Hunters catch them using nets and traps, then roast them with the skin on to make it easier to peel off later. The meat is then cut into pieces and spiced up with fresh ingredients like chives, onions, and hot peppers. The result is a dish that’s said to taste like chicken, with a unique texture that sets it apart.

Eating iguanas offers a delicious way to help control their growing population. With recipes ranging from burritos to sausages, these reptiles are making a splash on dinner tables. Who knew tackling an invasive species could be so delicious?^[6]

4 Snakehead Fish

Snakehead fish might look intimidating with their sharp teeth and snake-like heads, but don’t let that scare you away from the dinner table. These invasive fish have become a problem in many U.S. waterways, but they’re also turning into a hidden gem for adventurous cooks. With firm, white meat that’s mild and clean-tasting, snakeheads are much more delicious than you might think.

Unlike other fish that live in murky waters, snakeheads don’t have that muddy taste. They prefer feeding on baitfish and insects, which gives their meat a fresh, sweet flavor. They’re also easy to fillet, with none of the tiny bones that make other fish a hassle in the kitchen. Whether you fry them up as crispy nuggets or grill them with a bit of seasoning, snakehead meat is versatile and delicious.

Cooking and eating snakehead fish helps to control their growing numbers while feeding a hungry local human population. From simple frying to more creative preparations, there are plenty of ways to turn these invaders into succulent dishes.^[7]

3 Asian Carp

Asian carp might not be the first fish that comes to mind for dinner, but they have some surprising qualities in the kitchen. With firm, white flesh and a mild flavor, they’re a versatile option for those interested in trying something different. Because these fish feed lower on the food chain, they are generally lower in contaminants compared to other freshwater species.

Handling Asian carp can be a bit tricky due to their intramuscular bones. However, they become more manageable with the right preparation methods, such as carefully filleting around the bones or using them in recipes that break down the fish. Some cooks have even developed unique dishes like “Flying Carp Wings” to make the most of this invasive species.

Eating Asian carp is one approach to managing their growing numbers in U.S. waterways. These fish have spread widely and can impact native species. Incorporating them into meals is one of several strategies being explored to address their environmental impact.^[8]

2 Wild Hog

In places like Texas, locals are hunting and cooking wild hogs to help control their booming population. These invasive animals, known for their destructive feeding habits, have spread across much of the United States, causing significant ecological damage. But with a bit of preparation, wild hog meat can be turned into a surprising delicacy.

The key to cooking wild hog is understanding its unique flavors and textures. Unlike domestic pork, wild hogs have a gamey taste due to their varied diet of plants and small animals. When prepared correctly, the meat can be tender and flavorful. Marinating the meat to enhance its taste and using slow cooking methods, like smoking or braising, helps break down tougher cuts, making the meat more palatable.

While handling wild hog, it’s crucial to take precautions due to potential diseases like trichinosis. Cooking the meat to an internal temperature of at least 145°F (62.8°C) ensures it’s safe to eat. With proper preparation, wild hog barbeque can be a central attraction at a summer dinner party.^[9]

1 Lionfish

Eating lionfish is more than just a culinary experience—it’s an environmental statement. This invasive species has disrupted marine ecosystems in the Atlantic and Caribbean, but its mild, flaky white meat makes it a surprisingly versatile ingredient. Lionfish can be grilled, fried, or even made into sushi rolls, absorbing flavors well and adding a unique twist to familiar recipes.

Handling lionfish requires some care due to their venomous spines, but once prepared, they’re as easy to cook as any other fish. By eating lionfish, you’re not just trying a new delicacy—you’re also helping to reduce their numbers and protect coral reefs from further damage. For those in search of a culinary adventure, lionfish offers a very exotic and unusual choice.^[10]
