For the Marinade
• Extra Virgin Olive Oil – Provides moisture and richness; substitute with avocado oil for a similar flavor.

• Garlic (minced) – Enhances flavor with aromatic notes; garlic powder (1/2 teaspoon) can be a quick alternative.
• Fresh Parsley (chopped) – Offers freshness and color; fresh cilantro makes a great substitute for a different flair.

For the Skewers

• Red Bell Pepper (cut into 1-inch pieces) – Adds sweetness and color; other bell peppers or zucchini can be used for variety.

Step‑by‑Step Instructions for Perfectly Charred Grilled Seafood Skewers
Step 1: Soak the Skewers
Begin by soaking wooden skewers in water for at least 30 minutes. This will prevent them from burning on the grill while cooking your delicious grilled seafood skewers. Place your skewers in a dish of water and let them soak, ensuring they are completely submerged for even results.
Step 2: Prepare the Marinade
In a mixing bowl, whisk together ¼ cup of extra virgin olive oil, 2 tablespoons of freshly squeezed lemon juice, 2 cloves of minced garlic, 2 tablespoons of chopped fresh parsley, 1 teaspoon of dried oregano, and a pinch of red pepper flakes, salt, and black pepper. This zesty marinade will greatly enhance the flavor of your seafood and vegetables.
Step 3: Marinate the Seafood and Veggies
In a large bowl, combine 1 pound of peeled and deveined large shrimp, 1 pound of large sea scallops, 1 cup of 1-inch pieces of red bell pepper, 1 cup of 1-inch pieces of green bell pepper, and 1 cup of red onion wedges. Pour about three-quarters of the marinade over the mixture, toss gently to ensure even coating, and let it marinate for 15-20 minutes while you preheat the grill.
Step 4: Thread the Skewers
Once marinated, carefully thread the shrimp, scallops, and vegetables onto the soaked skewers. Alternate between the seafood and vegetables, leaving a little space between each piece to promote even cooking. This will help each item reach that perfect charred exterior while retaining its tender interior.
Step 5: Preheat the Grill
Preheat your grill to medium-high heat, aiming for a temperature between 400°F to 450°F (200°C to 230°C). Make sure to clean the grates thoroughly with a grill brush to remove any residuals, then oil the grates with a paper towel dipped in vegetable oil to prevent sticking.
Step 6: Grill the Skewers
Place the skewers on the preheated grill and cook for about 3-4 minutes on each side. You will know they are done when the shrimp turns pink and opaque, and the scallops are cooked through with a golden brown sear. During the last minute of grilling, brush the skewers with the reserved marinade for an extra punch of flavor.
Step 7: Serve and Enjoy
Once the grilled seafood skewers are perfectly charred and cooked, remove them from the grill and let them rest for a couple of minutes. Serve immediately alongside your favorite sides, allowing the vibrant colors and aroma to entice everyone at the table into enjoying this delicious meal together!

How to Store and Freeze Grilled Seafood Skewers
Fridge: Store leftover grilled seafood skewers in an airtight container in the refrigerator for up to 2 days. This helps maintain their freshness and flavor.
Freezer: If you’d like to freeze any cooked skewers, wrap them tightly in plastic wrap and then seal in a freezer bag for up to 2 months. Thaw in the fridge before reheating.
Reheating: To preserve texture, gently reheat skewers in a skillet over low heat or in a microwave, covered for 30 seconds at a time until warmed through. Enjoy the flavors of your grilled seafood skewers again!
Room Temperature: Serve grilled skewers immediately for the best flavor, but if needed, they can be kept at room temperature for about 1 hour before serving.
Expert Tips for Grilled Seafood Skewers
-
Marination Time: Avoid leaving seafood in the marinade for more than 30 minutes, as it can become mushy and lose its texture.

Uniform Size: Ensure all seafood and vegetable pieces are cut into similar sizes. This helps them cook evenly and achieve that perfect char.
-
Skewer Alternating: Alternate seafood and vegetables on the skewers, leaving a small gap between each piece. This promotes even cooking and better heat circulation.
-
Preheat Grill: Always preheat your grill to the correct temperature before placing the skewers on it. A hot grill ensures perfect searing of your grilled seafood skewers.
-
Use Reserved Marinade: Brush the skewers with the reserved marinade during the last minute of cooking for an added burst of flavor, but be careful not to do this too soon to avoid burning.
-
Avoid Overcrowding: Don’t overcrowd the skewers; this helps in achieving that beautiful char without steaming the seafood and veggies.

Grilled Seafood Skewers Recipe FAQs
What kind of seafood is best for grilling?
Absolutely! Large shrimp and sea scallops are ideal choices for grilling. Their textures hold up well on the grill, becoming beautifully charred while remaining juicy. You can also experiment with firm white fish like halibut or even add chunks of salmon to the mix for delicious variations.
How do I store leftover grilled seafood skewers?
Simply store any leftovers in an airtight container in the refrigerator for up to 2 days. Make sure the container is tightly sealed to maintain freshness. When you’re ready to enjoy them again, I recommend gently reheating in a skillet over low heat to preserve that succulent texture.
Can I freeze grilled seafood skewers?
Yes, you can freeze them! First, allow the skewers to cool completely. Then, wrap them tightly in plastic wrap and place them in a freezer bag or airtight container. They will keep well in the freezer for up to 2 months. When you’re ready to eat, just thaw them overnight in the fridge before reheating.
What should I do if my seafood is overcooked?
If you find your seafood is slightly overcooked, don’t worry too much! Adding a squeeze of fresh lemon juice right before serving can help reintroduce moisture and brighten up the flavors. Next time, be sure to watch the cooking time closely—shrimp generally need just 3-4 minutes per side to cook perfectly!
How can I make these skewers pet-friendly?
While these skewers are delicious for humans, it’s best to keep seafood away from pets. If you want to share something with your furry friends, consider setting aside some plain, cooked shrimp or fish without any seasoning for them, ensuring it’s safe and healthy.
How do I choose ripe vegetables for my skewers?
Look for vibrant, firm vegetables with no dark spots or blemishes. Bell peppers should be shiny and feel heavy for their size, while onions should be dry and firm. If you can, choose locally grown produce for the best flavor and freshness. Happy grilling!
