Essential Grilled Seafood Tips for Safety & Success

Before you start, remember these vital principles for grilling seafood:

• Freshness First: Always start with fresh, high-quality seafood from a reputable source. If using frozen, ensure it is thawed properly in the refrigerator, not at room temperature.¹US Food and Drug Administration. (2024). Selecting and Serving Fresh and Frozen Seafood Safely. https://www.fda.gov/food/buy-store-serve-safe-food/selecting-and-serving-fresh-and-frozen-seafood-safely. For more insights, refer (in 24h) to our upcoming article Ultimate Shrimp Buying & Cooking Guide for detailed buying, thawing, and cooking instructions.
• Prevent Sticking: Fish and shellfish are prone to sticking. Always preheat your grill thoroughly and clean the grates. Lightly oil the grates or brush the seafood itself with oil before placing it on the grill. Consider using an olive oil spray (non-aerosol) for even application.
• Don’t Overcook: Seafood cooks quickly. Overcooking leads to dry, rubbery, or tough results. Use a food thermometer to ensure proper internal temperatures for safety while preserving moisture and flavor.
• Cross-Contamination: Use separate cutting boards, utensils, and platters for raw and cooked seafood to prevent cross-contamination. Always wash hands thoroughly after handling raw seafood.
• Internal Temperatures: The USDA recommends specific minimum internal temperatures for various seafood to ensure safety . We will highlight these for each recipe.
  • Fish (fillets or steaks): 145°F (63°C)
  • Shrimp, Lobster, Scallops, Crab: Cook until flesh is opaque, pearly, or white, and firm. Shrimp turn pink and opaque. Lobster and crab shells turn bright red.
  • Clams, Mussels, Oysters: Cook until shells open during cooking. Discard any that do not open.
  • Calamari/Octopus: Cook until opaque and firm.

• Prep Time: 15 minutes
• Cook Time: 6 minutes
• Servings: 4

Ingredients:

• 1 lb large or jumbo shrimp, peeled and deveined
• 2 tbsp extra virgin olive oil (we highly recommend the La Tourangelle California Extra Virgin Olive Oil)
• 1 tbsp fresh lemon juice
• 2 cloves garlic, minced
• ½ tsp dried oregano or Italian seasoning (optional)
• Salt and freshly ground black pepper to taste
• Wooden or metal skewers (if using wooden, soak in water for 30 minutes). Consider the MOCUMEOI Metal Skewer for Grilling.

Instructions:

1. In a medium bowl, combine olive oil, lemon juice, minced garlic, oregano (if using), salt, and pepper. Add shrimp and toss to coat evenly. Marinate for 15 minutes at room temperature.
2. While shrimp marinates, preheat your grill to medium-high heat (around 400-450°F / 200-230°C). A cooking thermometer will make it easier to get this step right. Clean and lightly oil the grates.
3. Thread shrimp onto skewers, leaving a small space between each piece for even cooking. Do not overcrowd.
4. Place shrimp skewers on the preheated grill. Grill for 2-3 minutes per side, for a total of 4-6 minutes, until shrimp turn pink and opaque throughout. The internal temperature should reach 145°F (63°C).²Gordon Food Service. (2023).Safe Minimum Cooking Temperatures. https://gfs.com/en-us/ideas/safe-minimum-cooking-temperatures/
5. Remove from grill, garnish with fresh parsley, and serve immediately.

Health & Safety Info: Shrimp is high in protein, very low in calories and fat, and rich in selenium and omega-3 fatty acids. These nutrients support thyroid function, immunity, and reduce inflammation. Cook shrimp to an internal temperature of 145°F (63°C) to ensure safety.

Health & Safety Info: Salmon is an excellent source of omega-3 fatty acids (EPA and DHA), which are crucial for heart health, brain function, and reducing inflammation . It also provides high-quality protein and vitamin D. Cook to an internal temperature of 145°F (63°C) as advised by the USDA.³Food Safety and Inspection Service. (2025). Safe Minimum Internal Temperature Chart. USDA. https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/food-safety-basics/safe-temperature-chart.

3. Grilled Seafood: Tuna Steaks

Bioaccumulation and Trophic Transfer of Heavy Metals in Marine Fish: Ecological and Ecosystem-Level Impacts. National Library of Health. https://pmc.ncbi.nlm.nih.gov/articles/PMC12028879 Pregnant women, young children, and those with compromised immune systems should consult dietary guidelines regarding consumption.⁸Food Safety and Inspection Service (FSIS).

4. Serve immediately, garnished with fresh parsley and an extra squeeze of lemon.

Health & Safety Info: Calamari is low in calories and fat, and high in protein. It’s a good source of vitamin B12 and selenium. Its quick-cooking nature means it can become tough if overcooked. Ensure it’s opaque throughout for safety.

9. Grilled Seafood: Clams

Description: Fresh clams grilled in their shells with garlic butter and herbs, opening beautifully to reveal their tender, briny meat. Grilling clams adds a wonderful smoky dimension that steaming can’t replicate.

• 4 tbsp unsalted butter, melted
• 2 cloves garlic, minced
• 1 tbsp fresh parsley, chopped
• Salt and freshly ground black pepper to taste
• Lemon wedges for serving

Instructions:

2. Prepare Garlic Butter: In a small bowl, combine melted butter, minced garlic, chopped parsley, salt, and pepper.
3. Preheat grill to medium-high heat (around 400-450°F / 200-230°C). Clean the grates.
4. Place clams directly on the preheated grill. Close the grill lid.
5. Grill for 5-7 minutes, checking frequently, until the shells fully open.
6. Using tongs, carefully remove the opened clams from the grill. Discard any clams that do not open after 7 minutes.
7. Arranged opened clams on a platter. Drizzle generously with the prepared garlic butter. Serve immediately with lemon wedges.

Health & Safety Info: Clams are high in protein, iron, and vitamin B12, and low in fat and calories. They are also a good source of selenium and manganese. Crucially, only consume clams that fully open during cooking; discard any that remain closed as they may have been dead prior to cooking and could pose a health risk .

10. Grilled Seafood: Octopus

Description: Tender octopus, pre-cooked and then marinated in olive oil and lemon, grilled for a smoky, flavorful, and slightly charred dish. Grilling imparts an incredible texture and depth of flavor to octopus.

• Prep Time: 1 hour 45 minutes (includes pre-cooking time)
• Cook Time: 8 minutes
• Servings: 4

Ingredients:

• 2 lbs octopus, cleaned (fresh or frozen)

• 2 tbsp fresh lemon juice
• 2 cloves garlic, minced
• 1 tsp dried oregano
• Salt and freshly ground black pepper to taste
• Lemon wedges and fresh herbs (e.g., parsley, dill) for serving

Instructions:

1. Pre-Cook Octopus: This step is crucial for tenderness. If using fresh octopus, place it in a large pot of unsalted water (no need for tenderizers). Bring to a boil, then reduce heat and simmer gently, covered, until very tender, about 45 minutes to 1.5 hours, depending on size. (A small octopus might take 45 min, a large one up to 2 hours). A fork should easily pierce the thickest part. If using frozen, pre-cooked octopus, you can skip this step or simmer for 15-20 minutes to tenderize further.
2. Once tender, remove octopus from water and let it cool. Once cool enough to handle, cut the body into pieces and separate the tentacles.
3. Marinate: In a bowl, combine olive oil, lemon juice, minced garlic, oregano, salt, and pepper. Add the cooled octopus pieces and toss to coat. Marinate for at least 1 hour at room temperature, or up to 4 hours in the refrigerator.
4. Preheat grill to high heat (around 450-500°F / 230-260°C). Clean and lightly oil the grates.
5. Place marinated octopus on the preheated grill. Grill for 3-4 minutes per side until beautifully charred and slightly crispy on the exterior. The internal temperature should reach 145°F (63°C) .
6. Serve immediately with extra lemon wedges and fresh herbs.

Health & Safety Info: Octopus is high in protein and low in fat, making it a lean choice. It’s an excellent source of iron, vitamin B12, and selenium. Proper pre-cooking is essential for tenderness and digestibility.
