Sweet, sweet summer is on its way. That means lazy days, fired-up grills, and al fresco dining. It also opens the door for plenty of mistakes to be made when cooking and entertaining.

When it comes to grilling fish, there are many things that people do wrong. Frankly, the makeup of fish is not quite like other grill-ables such as chicken, pork, or steak. That said, they behave a bit differently on the grill, whether it’s charcoal or gas. So we reached out to an expert in the field to point them out, setting you up for better salmon, halibut, and grouper dinners this grilling season.

Not prepping your fish for the grill

“Whether you choose to marinate or not, preparing your seafood with a rub or marinade before grilling will deliver big in the taste department,” Kleiner says. “Even something as simple as a salt rub or basic marinade of olive oil, lemon, herbs and salt (which is my fallback when grilling fish!) will help to lock in taste.”

Don’t shy away from something a little more complex either, like a marinade involving some powerful citrus-like yuzu. And make that fish all the better with a good side when the time comes, like mango salsa or grilled asparagus with lemon.

Not cleaning the grill prior to cooking

“Cooking seafood—or any food—on a grill that hasn’t been cleaned likely means your food will pick up the burnt taste of the food cooked on the grates before,” Kleiner says. “For the best tasting grilled seafood, gently scrape the grates before or after heating (though cleaning after heating may help dislodge stubborn burnt pieces).”

Think of it in terms of relativity, which is a great way to look at most things involving food. Just as improperly stored food items in your fridge and affect the flavors of other leftover items in there, what was previously on your grill and impart unwanted flavors to what you’re presently cooking. Start clean; that’s the way to go.

Not oiling or preheating the grill properly

“Just like oven cooking, you’ll get the most evenly, best-tasting food when the grill has been preheated,” Kleiner says. “Let the grill heat up for about ten minutes, then oil with a high-smoke point oil (avocado oil works well) to help prevent the food from sticking.”

Starting to early can dry seafood out or result in a fish that’s partially cooked in one area and fully cooking in another. Also, keep in mind where the major heat spots are on your grill and lay your proteins out accordingly.

Not grilling skin-side down

This one is pretty easy to remember, as there isn’t much wiggle room. “If your seafood has skin on it, grill with the skin side down,” Kleiner says. “And let it cook until almost done before flipping to prevent sticking.” Being a little more patient here will allow for a nice, clean release when it’s time, not to mention a crispy and delicious skin layer.

Not cooking for the right amount of time

While adequate cooking time depends on the species, a good rule of thumb to keep in mind when cooking fish is to grill ten minutes for every inch of thickness,” Kleiner says. “If your fish is about one inch thick at the thickest part, cook for about ten minutes (and don’t flip until at least halfway through the cooking time). If your fish is one-and-a-half inches at its thickest, grill for about 15 minutes and so on.”

With the above in mind, fish grilling season will certainly be a more enjoyable and flavorful affair. Also keep in mind the seasonality of seafood and chat up your local fishmonger or seafood specialist. If you happen to live near the sea, all the better. If not, there are still great ways to get fresh seafood online.

Grilling whole fish is always fun and can be a show-stopped when hosting a meal. We suggest smaller salmon species, sea bass, trout, or red snapper. But play around and see what’s available locally in your neck of the woods.

Gas vs. charcoal grilling: Which is better?
It's more complex than you might think
Food cooking on grill

Gas vs. charcoal grilling. The subject of grilling can be a passionately debated one, no matter the topic at hand. How to perfectly cook ribs, the best way to smoke a brisket, whether or not any one particular meat should be sauced, and how to properly season a steak are all arguments waiting to happen in certain foodie circles. Admittedly, we've been in more than our share of these debates, for grilling is a subject worth our passion. Perhaps the most heated of all of these grilling topics is which type of grill is best. Ask any at-home grill master whether they prefer a gas or charcoal grill, and you're bound to get some fiery feelings either way.

As with most heavily debated topics, the answer is neither black nor white, but lies somewhere in the grayish middle. When it comes to grilling, there are many features to consider. It's important to ask yourself which of these is most important to you. Is it affordability? Convenience? The final flavor of your dish? Temperature control? Ease of use? Whether you should use a gas or charcoal grill will greatly depend on you. Because, unfortunately, there isn't a simple "one-size-fits-all" solution.

Despite our associations with summertime pool parties and backyard barbecues, summer isn't the only season for grilling. Autumn grilling is a pleasure, too, especially when the foods you prepare capture the essence of the fall season. From using extra wood chips in the coals to grilling on cedar planks to adding apple and maple to myriad meat recipes, there are tons of delicious reasons autumn is actually the best grilling season.

Don't have a grill? Check out your local stores, as there might be some "end-of-season" sales. We recommend trying to snag any of these grills.

Steak Diane dish

Some of the best dishes have, tragically, been lost to time. Retro staples of our childhoods that no one has thought of in years cleared from our memories to make way for a more modern cooking flare. Admittedly, this isn't always a negative thing. I, for one, am quite happy to see the back end of jellied meats, for example. But there are too many culinary gems lost to history, sitting restlessly in the pages of dusty cookbooks. We toy with nonsensical recipes like vegan scallops with rhubarb foam while rich, hearty, deliciously complex, timeless recipes like Steak Diane go forgotten. We say it's time to change that.
