The Best Seafood for Grilling on Skewers

The key to amazing Grilled Seafood Skewers is choosing seafood that can withstand the heat of the grill. You want pieces that are firm enough to be threaded onto a skewer and that cook relatively quickly.

Top Choices for Your Skewers

• Shrimp: A classic choice for a reason. Use large or jumbo shrimp (16-20 count) for the best results, as they are less likely to overcook.
• Sea Scallops: Their sweet, delicate flavor is a perfect match for the smoky char of the grill. Look for large sea scallops that are uniform in size.
• Firm Fish: Cubes of firm fish work wonderfully. Consider swordfish, halibut, salmon, or cod. Cut them into 1 to 1.5-inch cubes so they stay on the skewer.

The Secret to Flavorful Seafood: The Marinade

A great marinade does two things: it tenderizes and it adds a massive amount of flavor. This simple lemon-garlic-herb marinade is bright, zesty, and perfectly complements the natural sweetness of the seafood without overpowering it. The olive oil ensures the seafood doesn’t dry out on the grill.

Ingredients You’ll Need

For the Lemon-Garlic Marinade:

• 1/3 cup extra virgin olive oil
• 1/4 cup freshly squeezed lemon juice
• 3 cloves garlic, minced
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon dried oregano
• 1/2 teaspoon red pepper flakes (optional, for a little heat)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

For the Skewers:

• 1 lb large shrimp, peeled and deveined
• 1 lb large sea scallops, side-muscle removed
• 1 large red bell pepper, cut into 1-inch pieces
• 1 large green bell pepper, cut into 1-inch pieces
• 1 large red onion, cut into 1-inch wedges
• 8-10 wooden or metal skewers

How to Make Grilled Seafood Skewers: Step-by-Step

Follow these simple steps for a flawless grilling experience.

1. Prep the Skewers: If you’re using wooden skewers, soak them in water for at least 30 minutes. This crucial step prevents them from burning on the grill.
2. Make the Marinade: In a small bowl, whisk together the olive oil, lemon juice, minced garlic, parsley, oregano, red pepper flakes, salt, and pepper.
3. Marinate the Seafood: In a large bowl, combine the shrimp, scallops, bell peppers, and red onion. Pour over about three-quarters of the marinade and toss gently to coat everything evenly. Let it marinate for 15-20 minutes. Don’t marinate for too long, as the acid in the lemon juice will start to “cook” the seafood. Reserve the remaining marinade for basting.
4. Assemble the Skewers: Thread the marinated seafood and vegetables onto the skewers, alternating between items. For example: shrimp, bell pepper, scallop, onion, and repeat. Don’t pack the items too tightly; leave a little space for the heat to circulate.
5. Grill to Perfection: Preheat your grill to medium-high heat (about 400-450°F or 200-230°C). Clean the grates well and oil them to prevent sticking. Place the skewers on the grill. Cook for about 3-4 minutes per side, turning once, until the shrimp are pink and opaque and the scallops are firm and cooked through. Baste with the reserved marinade once while grilling.

Expert Tips for the Perfect Skewers

• Don’t Overcook: Seafood cooks very quickly! Keep a close eye on the skewers. Overcooked shrimp becomes rubbery, and scallops become tough.
• Uniform Sizes: Cut your vegetables and choose seafood that are roughly the same size to ensure even cooking.
• Use Two Skewers: For larger pieces of fish or to prevent items from spinning, thread them onto two parallel skewers. This makes flipping much easier.
• Preheat and Oil Your Grill: A hot, clean, and well-oiled grill grate is the secret to getting a great sear and preventing the delicate seafood from sticking.

Variations and Customizations

One of the best things about these Grilled Seafood Skewers is how easy they are to customize.

Try Different Vegetables

Feel free to swap the bell peppers and onion for other grilling favorites like zucchini, yellow squash, cherry tomatoes, or mushrooms.

Add a Different Protein

Add some surf-and-turf flair by threading on cubes of sirloin steak or chicken. Just be sure to adjust grilling times accordingly.

What to Serve with Seafood Skewers

These skewers are a fantastic centerpiece for any meal. For a truly complete and delicious experience, pair them with sides that complement the fresh, smoky flavors. A simple bed of rice or quinoa is always a great choice. For something a little more exciting, try a vibrant salad like this Refreshing Strawberry Cucumber Salad or a hearty Mexican Street Corn Salad. You could also serve them with a flavorful dipping sauce; while it’s made for pizza, this creamy garlic sauce is surprisingly delicious with grilled shrimp.

Storing and Reheating

Store leftover skewers in an airtight container in the refrigerator for up to 2 days. You can enjoy them cold over a salad or reheat them gently. To reheat, place them in a skillet over low heat or in a microwave for 30-60 seconds—just be careful not to overcook them.

Equipment

• 8 Skewers Metal or wooden
• 2 Mixing bowls

Method

 

1. If using wooden skewers, soak them in water for at least 30 minutes to prevent them from burning on the grill.
2. In a small bowl, whisk together the olive oil, lemon juice, minced garlic, parsley, oregano, red pepper flakes, salt, and pepper to create the marinade.
3. In a large bowl, combine the shrimp, scallops, bell peppers, and red onion. Pour about three-quarters of the marinade over everything and toss gently to coat. Let it marinate for 15-20 minutes. Reserve the remaining marinade for basting later.
4. Thread the marinated seafood and vegetables onto the skewers, alternating between the items. Avoid packing them too tightly to ensure even cooking.
5. Preheat your grill to medium-high heat (400-450°F / 200-230°C). Clean and oil the grates. Place the skewers on the grill and cook for 3-4 minutes per side, until the shrimp are pink and opaque and the scallops are cooked through. Baste with the reserved marinade during the last minute of cooking.

Notes

Tip 1: Do not marinate the seafood for longer than 30 minutes, as the citrus juice will begin to break down the proteins and make it mushy.
Tip 2: Ensure all your ingredients are cut to a similar size for even cooking.
Tip 3: A well-oiled grill grate is essential to prevent the delicate seafood from sticking.
