These grilled seafood boil skewers became our family's signature summer dish after I got tired of the mess that comes with traditional seafood boils but still craved all those incredible flavors. The idea hit me during a particularly chaotic backyard party when I was trying to figure out how to serve seafood boil to a crowd without everyone getting completely messy. Threading everything onto skewers and grilling them with that spicy crab boil garlic butter creates all the same amazing flavors but in a much more civilized, shareable format. Now these are what everyone requests when we fire up the grill.
The first time I made these for a neighborhood cookout, people kept asking where I'd learned to make "fancy seafood boil." When I explained it was just regular seafood boil ingredients on skewers, everyone wanted the recipe immediately. My neighbor Jim, who's normally pretty reserved about food, ate three skewers and declared them "better than any restaurant seafood boil" he'd ever had.
Essential Ingredient Guide
- Large raw shrimp: Choose shrimp that are already peeled and deveined to save time. The larger size holds up better on skewers and on the grill.
- Andouille sausage: Provides that smoky, spicy flavor that's essential to seafood boil. Slice it thick enough to stay on the skewers but thin enough to cook through quickly.
- Petite potatoes: Red or gold potatoes work perfectly because they hold their shape well after parboiling and grilling. The smaller size cooks more evenly.
- Fresh corn on the cob: Cut into thick rounds that will thread easily onto skewers while providing that sweet corn flavor in every bite.
- Tony Chachere's seasoning: The bold Creole seasoning gives authentic Louisiana flavor. Don't substitute regular Old Bay - the flavor profile is different.
- Quality butter: Use real unsalted butter for the garlic butter mixture. The fat content and flavor are crucial for the final result.

Complete Preparation Process
- Potato and Corn Prep:
- Start by bringing a large pot of generously salted water to a rolling boil. Add your petite potatoes and cook for 12-15 minutes until they're fork-tender but still hold their shape. During the last 5 minutes, add the corn rounds to the same pot. Drain everything well and let it cool enough to handle safely.
- Skewer Assembly Strategy:
- Thread your ingredients onto the skewers in alternating patterns - shrimp, sausage, potato, corn - so each skewer gets a good variety. Don't pack everything too tightly or it won't cook evenly. Leave small gaps between pieces to allow heat circulation and even cooking.
- Seasoning Application:
- Brush the assembled skewers lightly with oil to prevent sticking, then season all surfaces generously with the Tony Chachere's Bold Creole Seasoning. Make sure every piece gets coated because this is what gives you that authentic seafood boil flavor.
- Garlic Butter Creation:
- Melt the butter in a small saucepan over low heat, then stir in the crab boil seasoning, minced garlic, and lemon juice if using. Keep this mixture warm but not hot - you don't want to burn the garlic. The butter should be fragrant and well-combined.
- Grill Preparation:
- Preheat your grill to medium-high heat, around 400-450 degrees. Make sure your grates are clean and well-oiled to prevent sticking. You want direct heat for these skewers to get that nice char while cooking everything through.
- Grilling Technique:
- Place the skewers directly over the flame and grill for 2-3 minutes per side. The shrimp should turn opaque and pink, while everything else develops a light char. Don't overcook the shrimp or they'll become tough and rubbery.
- Final Basting:
- During the last minute of cooking, brush the skewers generously with your garlic crab boil butter. This creates an incredible flavor coating and helps everything caramelize slightly. Remove from the grill and drizzle with additional butter before serving.
My first attempt was a disaster because I didn't parboil the potatoes long enough and they were still hard when everything else was done. I ended up with overcooked shrimp and undercooked potatoes, which nobody wanted to eat. Now I always test the potatoes with a fork before adding them to skewers - they should be tender but still hold their shape.
Potato Parboiling Secrets
Getting the potatoes just right is crucial for success. They need to be cooked enough that they'll finish properly on the grill but not so soft that they fall apart when you thread them. Test with a fork - it should go in easily but the potato should still feel firm and hold its shape.
Skewer Assembly Tips
The way you arrange ingredients on the skewers affects both cooking and presentation. Alternate different items so each skewer gets variety, and don't pack things too tightly or they won't cook evenly. Leave small spaces between pieces for heat circulation.
Shrimp Cooking Perfection
Large shrimp cook quickly, so watch them carefully to avoid overcooking. They're done when they turn pink and opaque - usually just 2-3 minutes per side depending on their size. Overcooked shrimp become tough and chewy, which ruins the whole experience.
Garlic Butter Magic
That crab boil garlic butter is what transforms these from good to incredible. Keep it warm throughout the grilling process so it stays liquid and brushes easily. The combination of butter, garlic, and crab boil seasoning creates an authentic Louisiana flavor that coats everything perfectly.
Grill Temperature Control
Medium-high heat gives you the perfect balance of cooking through without burning. Too hot and the outside chars before the inside cooks; too cool and you don't get that nice grilled flavor and texture. Listen for steady sizzling when you put the skewers down.
Perfect Serving Style
These skewers are best served immediately while everything is hot and the butter is still melted and fragrant. Provide plenty of napkins because they can be gloriously messy to eat. The combination of flavors and textures in each bite really does capture that classic seafood boil experience.
Make-Ahead Strategies
You can parboil the potatoes and corn earlier in the day and assemble the skewers a few hours ahead. Just cover and refrigerate until you're ready to grill. The garlic butter can also be made ahead and gently rewarmed when needed.
Creative Variations
While this combination is classic, you can customize based on what you like or what's available. Some people love adding mushrooms or bell peppers to the skewers. You could also use different types of sausage or add other seafood like scallops.
Storage and Reheating
These are definitely best eaten fresh off the grill, but leftovers can be stored in the refrigerator for a day or two. Reheat gently in the oven or microwave, adding a bit more garlic butter to restore moisture and flavor.
