Gather the ingredients to prepare this grilled whole tilapia recipe

The recipe for grilled whole tilapia is one of the more uncomplicated dishes you'll make, and it requires only a handful of ingredients — the majority of which you probably already have in your kitchen cupboard and fresh herb garden. Before you get started preparing this undeniably tasty dish, you'll need to round up whole tilapia, green onions, fresh dill, lemon, extra-virgin olive oil, salt, and black pepper. Hopefully, you already have a few of these items stashed at home, and you don't need to get too much at the store. Once you lay everything out on the counter, get excited, because it's time to begin cooking! 

Descale and gut the tilapia

Sometimes, the grocery store prepares the tilapia for cooking when you purchase it, but other times, they do not. If the fish isn't prepared yet, you must descale and cut it. But if it is, you can go ahead and skip this step. "Tips for descaling is just make sure you do it very slowly, perhaps wear gloves, and hold the fish up to the light to see if there are any glass-like looking scales left," Olayinka says. Once you're finished with that, pat the fish so that it is very dry.

Brush the fish

When the fish is dry, you're ready for the next step. Simply brush both sides with extra-virgin olive oil. After that, the tilapia is ready for some seasoning. Put salt and pepper on both sides of the fish, and also be sure to add some inside the cavity. This ensures that all of the flavors will soak in quite nicely while it's cooking. Salt and pepper is such a simple combination, but it provides a great addition to this main course, so don't skip out on this step!

It's lemon and greens time

It's time to cut your lemon in half. Using only half of the lemon, cut it into slices to use for cooking. At this time, you can also cut the green onions in half. Next, put the lemon slices, onions, and dill into the cavity of the fish. You'll use about half for each of the fish so they're evenly divided. This combination of ingredients is so incredibly simple, but it makes the tilapia taste super tasty and fresh — trust us on this one.

Grill the fish

The fish is officially ready to cook. Wasn't the prep work surprisingly easy? That's certainly one of the highlights of this gem of a recipe. 

Place both pieces of fish on the grill grates, grilling each side for about 10 to 15 minutes. Pro tip: You'll know it's ready to turn over when it's not sticking to the grill, and it will pull away very easily.

As far as grilling tools are concerned, a thin metal spatula works best as opposed to silicon. Olayinka also says that tongs should not be used for flipping and working with the delicate fish, because they could pierce it. Alternatively, Olayinka shares that you can cook the fish in the oven, but doesn't advise using a pan.

Turn the fish over, and grill the other side

After the fish has cooked for 10 to 15 minutes on the first side, give it a good flip, and let it cook on the other side. Once it's cooked all the way through, remove it from the grill. Be sure to display the grilled whole tilapia on a pretty serving platter so it has the presentation it deserves. The tilapia is excellent with a chopped dill garnish and a few fresh lemon slices, too. "This fish is best served with a fresh salad, roasted sweet potatoes, or a rice and stew dish," Olayinka says. 

Whoever you serve this delicious fish dish to will think you spent all afternoon putting it together — but we won't tell them that's not the case. Now, it's prime time to dig in and fully enjoy your masterpiece!
