Salmon is an excellent choice for grilling due to its firm texture, rich flavour, and high nutritional value. It is packed with omega-3 fatty acids, which are beneficial for heart health, as well as being a great source of protein, vitamins, and minerals. When grilled, salmon retains its moisture while absorbing a smoky, charred flavour that enhances its taste. Grilling salmon not only gives it a beautiful crispy skin but also seals in its juices, making it incredibly tender and juicy.

Grilling salmon is quicker and simpler than other cooking methods, making it the perfect dish for busy evenings or weekend BBQs. With just a few basic tips and the right grill, you can turn out perfectly grilled salmon every time. By the end of this article, you’ll have everything you need to make your next grilled salmon experience a success.

Choosing the Right Salmon

The first step in creating the perfect grilled salmon is choosing the right fish. While salmon is available in various types and cuts, understanding what to look for will help you make an informed decision.

Wild vs. Farmed Salmon

• Wild Salmon: Wild-caught salmon, such as Sockeye, Coho, and King salmon, is generally leaner and has a more robust, natural flavour. It’s considered a healthier option due to its lower fat content and higher levels of omega-3 fatty acids. Wild salmon is typically more expensive but offers a better overall taste and sustainability.

• Farmed Salmon: Farmed salmon is more affordable and has a higher fat content, which makes it moist and tender. While some people prefer the milder flavour of farmed salmon, it may not have the same nutrient profile as wild-caught.

Best Types of Salmon for Grilling

• King Salmon: The thickest and fattiest variety, ideal for grilling as it stays moist and tender.
• Coho Salmon: Slightly leaner, but still a great option for grilling with a rich flavour.
• Sockeye Salmon: Known for its deep red colour and slightly stronger flavour.
• Atlantic Salmon: Typically farmed, this variety is more tender and works well on the grill but is milder in taste.

When grilling, it’s best to choose skin-on fillets as the skin helps hold the fish together during cooking, especially over direct heat.

Preparation Steps for Grilling Salmon

Once you’ve chosen the right salmon, it’s time to prepare it for grilling. Proper preparation ensures that your salmon cooks evenly and retains its natural moisture and flavour.

Defrosting and Cleaning

If you’ve purchased frozen salmon, it’s essential to defrost it properly to avoid affecting its texture. The best method is to thaw it overnight in the refrigerator. If you’re in a hurry, you can place the fish in a sealed bag and submerge it in cold water for about 30 minutes.

Before grilling, rinse the salmon under cold water and pat it dry with paper towels. Removing excess moisture helps achieve a crispier exterior when grilling.

Drying and Oiling the Salmon

Dry the salmon thoroughly before seasoning it. This will allow the seasoning to stick better and prevent the fish from steaming on the grill. Lightly brush the salmon with olive oil to prevent sticking and promote even cooking.

Seasoning the Salmon

Salmon has a natural richness that pairs wonderfully with a variety of seasonings. Here are some seasoning ideas to enhance the flavour of your salmon:

• Basic Seasoning: A simple combination of kosher salt and freshly cracked black pepper is often enough.
• Garlic and Paprika: For a smoky, savoury touch, add garlic powder and paprika.
• Lemon and Dill: A classic combination of lemon zest, lemon juice, and fresh dill.
• Herb Marinade: Create a fresh marinade with olive oil, garlic, oregano, and thyme.

For a more complex flavour, you can prepare a spicy lime-harissa marinade or a soy sauce and ginger marinade.

Grilling Techniques

Once your salmon is prepped and seasoned, it’s time to fire up the grill. The right grilling technique is crucial for achieving the perfect grilled salmon.

Gas vs. Charcoal Grills

• Gas Grills
  Gas grills provide precise control over the temperature, making them a great choice for beginners. They allow you to maintain an even heat and avoid hot spots, which can burn the fish.
• Charcoal Grills
  Charcoal grills provide a deeper smoky flavour, ideal for those who love the traditional BBQ taste. However, they require more attention to ensure the heat is consistent.
  

If you’re looking for a great charcoal grill, we recommend the Outsunny Charcoal BBQ Trolley with Adjustable Charcoal Grate. Its adjustable charcoal pan lets you create different smokey flavours and is perfect for cooking up to 12 burger patties or a few pieces of salmon at once.

Preheating the Grill

For the best grilling results, preheat your grill to around 450°F-500°F (230°C-260°C). For charcoal grills, ensure the coals are evenly distributed and ready before placing the salmon on the grill. A gas grill should be preheated for 10-15 minutes on high heat.

Direct vs. Indirect Heat

• Direct Heat: This method is ideal for grilling salmon fillets or smaller pieces, where you place the fish directly over the heat source. It’s great for getting crispy edges and grill marks.

• Indirect Heat: Use this method if you’re grilling a thicker piece of salmon or want a slower cooking process. Move the fish to a cooler part of the grill after searing to prevent it from drying out.

Step-by-Step Grilling Instructions

1. Oil the Grill Grates
   Prevent the salmon from sticking by brushing the grill grates with oil using a paper towel or grill brush.
2. Place the Salmon on the Grill
   Start by placing the salmon flesh-side down. Close the lid and let it cook for 2-3 minutes.
3. Flip the Salmon
   Once you see a layer of opaque flesh, carefully flip the salmon using tongs or a fish spatula.
4. Cook Skin-Side Down
   Let the salmon cook skin-side down for another 3-5 minutes, depending on thickness. A good rule of thumb is 8-10 minutes of grilling for every inch of thickness.
5. Check for Doneness
   The best way to ensure your salmon is cooked properly is by checking the internal temperature. It should be between 125°F-130°F (51°C-54°C) when done.

Marinating Salmon for Extra Flavor

Marinating your salmon can bring additional layers of flavour, enhancing the natural richness of the fish. Here are a few marinade ideas:

• Lemon Garlic Marinade
  Combine lemon juice, olive oil, garlic, and herbs like dill or thyme.
• Soy Sauce and Ginger Marinade
  For an Asian twist, mix soy sauce, ginger, and honey.
• Spicy Lime-Harissa Marinade
  A blend of lime juice, harissa, and a bit of honey for a kick.

Grilling Salmon in Foil

Grilling salmon in foil is an excellent way to lock in moisture and keep the fish tender. This method also prevents any marinades from dripping into the grill, ensuring that your salmon is infused with flavour throughout the cooking process. Whether you’re a grilling novice or a seasoned BBQ enthusiast, foil grilling is a foolproof method that guarantees juicy, perfectly cooked salmon every time.

Benefits of Grilling in Foil

1. Retains Moisture: One of the key benefits of grilling salmon in foil is that it traps the fish’s natural moisture, creating a steaming effect that keeps the salmon tender and juicy. This is particularly helpful for avoiding dry salmon, which can occur when the fish is exposed directly to the grill’s heat for too long.
2. Helps Preserve Delicate Seasonings and Marinades: Since the foil packet seals in all the seasonings and marinades, they stay in close contact with the fish, ensuring the flavours are absorbed deeply. There’s no risk of the marinade dripping off or burning, as might happen when grilling without foil.
   
3. Ideal for Grills with Limited Space: If you’re using a grill with limited cooking space, like the Outsunny Charcoal BBQ, grilling salmon in foil is a perfect solution. The compact design of this grill allows you to use smaller areas for indirect cooking, such as placing foil packets on the cooler side of the grill.

Step-by-Step Guide to Grilling Salmon in Foil

1. Prepare the Foil: Start by placing a large piece of heavy-duty aluminium foil on a flat surface. Make sure the foil is large enough to fully wrap the salmon fillet. You can also use two layers of foil for added strength.
2. Oil the Foil: Lightly brush the foil with olive oil to prevent the salmon from sticking. You can also use butter if you prefer a richer flavour.
3. Place the Salmon on the Foil: Lay the seasoned or marinated salmon in the centre of the foil. You can add additional herbs, lemon slices, or even a pat of butter on top of the salmon for extra flavour.
4. Seal the Foil: Fold the foil over the salmon to create a packet, ensuring the edges are tightly sealed to keep all the juices in. This will allow the salmon to steam in its own juices and any added marinades, resulting in moist, tender fish.
5. Grill the Salmon: Place the foil packet on the grill, ensuring that the grill is preheated to medium heat. Close the lid and cook for 14 to 18 minutes, depending on the thickness of the salmon fillet. For a charcoal grill, place the foil packet over indirect heat to avoid direct contact with the flames, which can cause the salmon to overcook.
6. Check for Doneness: After the grilling time has passed, carefully open the foil packet and check the salmon for doneness. The salmon should easily flake with a fork and be opaque throughout. For best results, the internal temperature should reach 125°F to 130°F (51°C to 54°C). If it needs more time, rewrap the foil and continue grilling.
7. Serve and Enjoy: Once your salmon is cooked perfectly, remove it from the grill, and let it rest for a few minutes before serving. This will allow the juices to redistribute, keeping the fish tender and juicy.

Grill Accessories to Improve Your Cooking

The right grilling tools and accessories can make grilling salmon easier and more enjoyable. Here are some essential accessories that every grill master should have in their arsenal:

Grilling Baskets

Grilling baskets are perfect for cooking fish fillets, especially delicate ones like salmon. They make flipping your salmon a breeze, preventing it from falling apart. Choose a non-stick fish basket or a grill basket with a lid for a hassle-free grilling experience.

If you’re working with smaller pieces of salmon or want to cook several at once, the Outsunny Charcoal BBQ Trolley with Adjustable Charcoal Grate would be an excellent choice. It provides enough grilling space to accommodate multiple baskets, and its adjustable charcoal grate gives you more control over your cooking temperature.

Fish Spatula

A fish spatula is specially designed to handle delicate fish fillets. The thin, slotted blade allows you to slide it under the salmon gently, keeping the fillet intact while flipping it. Look for one with a long handle to protect your hands from the heat.

Cedar Planks for Smoking Flavour

For those who enjoy a smoky flavour, grilling salmon on a cedar plank is a must-try method. The wood imparts a rich, earthy taste to the fish. Soak the cedar plank in water for at least an hour before placing it on the grill. The plank will slowly release smoke, flavouring the salmon as it cooks. Cedar planks are available at most grill accessory stores, and some charcoal grills like the Outsunny BBQ Rotisserie Grill can be fitted with wooden planks for smoking.

Wood Chips and Smoker Boxes

Adding wood chips to your grill is another way to infuse your salmon with that signature smoky taste. Popular choices include applewood, hickory, and mesquite. Simply place the wood chips in a smoker box and position it over the heat source. As the chips heat up, they will release smoke that flavours the salmon. This is particularly effective when using a charcoal BBQ.

Serving Suggestions

Grilled salmon is a versatile dish that pairs well with a variety of sides. Here are some ideas to complement your meal:

Grilled Vegetables

Grilled vegetables make an excellent side dish for salmon. Try grilling some asparagus, bell peppers, or zucchini. These vegetables have a natural sweetness that pairs well with the smoky flavour of the salmon. To grill them, simply season with olive oil, salt, and pepper, and place them on the grill alongside the salmon.

Rice or Quinoa

A side of fluffy rice or quinoa provides a great base to serve alongside your salmon. For extra flavour, toss the rice with some lemon zest, herbs, or a drizzle of olive oil. Wild rice also works beautifully with salmon, offering a nutty texture that complements the fish’s richness.

Salads

A fresh salad can bring a refreshing contrast to the rich flavours of grilled salmon. Consider serving a citrusy green salad with arugula, fennel, and a lemon vinaigrette. Alternatively, a mango salsa adds a tropical touch that pairs wonderfully with the salmon’s flavours. For a creamy topping, try a dill sauce or a tangy yogurt-based dressing.

Sauces for Topping

Salmon is a canvas for a variety of delicious sauces:

• Dill Sauce: A creamy dill sauce made with sour cream or Greek yogurt complements the richness of the salmon.
• Mango Salsa: Sweet and tangy, this salsa adds brightness to the smoky salmon.
• Pesto: A rich, herby pesto made with basil, garlic, and olive oil gives your grilled salmon an extra punch of flavour.

Health Benefits of Grilled Salmon

Salmon is not only delicious but also offers numerous health benefits. It is an excellent source of omega-3 fatty acids, which are essential for brain health and heart health. Additionally, salmon is rich in protein, making it a great option for muscle repair and growth. It also contains vitamin D, which supports bone health and immune function.

Grilling salmon is a healthy method of cooking because it doesn’t require added fats or oils. The grill naturally sears the fish, locking in its natural juices while enhancing its flavour. For a well-rounded meal, serve your grilled salmon with healthy sides like roasted vegetables, quinoa, or a fresh salad.

Common Mistakes to Avoid

Grilling salmon is easy, but there are a few common mistakes to watch out for:

1. Overcooking the Salmon: Salmon cooks quickly, so avoid leaving it on the grill for too long. Remove the fish from the heat when it’s just opaque and flakes easily with a fork. Overcooking will lead to dry, tough salmon.
2. Not Oiling the Grill: Ensure your grill grates are well-oiled to prevent the salmon from sticking. Use a paper towel dipped in oil to grease the grates before cooking.
3. Using Too High Heat: High heat is necessary for searing the salmon, but cooking over too high heat for too long can cause the salmon to burn. Keep the temperature at medium-high to ensure an even cook.
4. Not Using a Thermometer: While the “fork test” is helpful, a meat thermometer can give you an exact reading to ensure your salmon is cooked perfectly every time. Aim for an internal temperature of 125°F-130°F (51°C-54°C).

Grilling salmon is an enjoyable and healthy way to cook this delicious fish. Whether you’re a beginner or a seasoned griller, following the right techniques and using the proper tools will help you achieve perfect results every time. From selecting the best salmon to mastering grilling techniques and experimenting with marinades, you have everything you need to create an unforgettable meal.

FAQs

1. Why does my salmon fall apart on the grill?
If your salmon is breaking apart, it’s likely because you’re flipping it too early or too often. Let the fish sear for a few minutes on one side until a crust forms before turning it gently with a fish spatula. Also, keeping the skin on helps hold the fillet together during grilling.

2. My salmon always sticks to the grill, how can I stop this?
To prevent sticking, make sure your grill grates are preheated and well-oiled. Brush both the grates and the salmon with a high smoke-point oil like canola or avocado oil. Starting with skin-side down can also reduce sticking.

3. What if I don’t have a grill thermometer?
If you’re grilling without a thermometer, test for doneness by checking the texture. Properly cooked salmon should flake easily with a fork and have an opaque color. Be cautious—salmon can go from perfectly cooked to dry quickly.

4. Can I grill salmon straight from frozen?
While it’s possible, it’s not ideal. Frozen salmon releases too much moisture as it cooks, which can result in a soggy texture. It’s best to fully thaw the salmon in the fridge or under cold water before grilling for better flavor and texture.

5. What should I do if my marinade burns on the grill?

Sugary marinades can burn easily over high heat. Pat the excess marinade off before placing the salmon on the grill and consider cooking over indirect heat. Alternatively, apply sweet glazes toward the end of grilling to avoid charring.
