The shrimp are the star here. Wild-caught Gulf shrimp are ideal if you can find them (ask at Whole Foods or your local seafood counter). Size matters—go for 16/20 count or larger. The butter should be good quality, but don’t stress over organic. I’ve used Land O’Lakes with great results. And yes, the tails stay on—they add flavor and look impressive.

No Worcestershire? Soy sauce plus a dash of fish sauce works in a pinch (but anchovies are traditional here). Out of hot sauce? Cayenne plus a splash of vinegar gets you close. Fresh lemon juice is non-negotiable though—bottled just doesn’t cut it. The green onions can be swapped for chives if that’s what you’ve got. And if you’re out of French bread, a crusty baguette does the trick.

This is best served immediately, but leftovers keep 2-3 days in the fridge. Reheat gently in a skillet with a splash of water. The sauce thickens as it cools, so thin it out if needed. Don’t freeze the shrimp—they’ll turn mushy. The bread? Toast and serve fresh for optimal sauce-soaking.

Step-by-Step Instructions for New Orleans-Style Barbecue Shrimp

Here’s how I make this iconic dish with bold, peppery sauce and juicy shrimp.

Step 1: Season and Prep the Shrimp

Rinse the 2 lb Large Shrimp under cold water and pat them completely dry with paper towels. I can’t stress this enough—dry shrimp sear better and absorb the sauce more effectively. Leave the tails on for that classic presentation.

In a large bowl, toss the shrimp with the 1 tbsp Coarse Black Pepper, 1 tsp Kosher Salt, 0.5 tsp Cayenne Pepper, 1 tsp Dried Rosemary, 1 tsp Dried Thyme, and 1 tsp Paprika. This spice blend is the heart of the dish. Let them sit for 10 minutes while you prep the rest.

Step 2: Create the Rich Butter Sauce Base

In a large, heavy skillet (cast iron works best), melt 1 cup Unsalted Butter over medium heat. Once melted, add the 6 cloves Garlic Cloves and cook for 1-2 minutes until fragrant but not browned—burnt garlic turns bitter.

Stir in the 0.25 cup Worcestershire Sauce, 2 tbsp Hot Sauce, and 2 tbsp Fresh Lemon Juice. Let this simmer for 3-4 minutes until it starts to reduce slightly and the flavors meld together. The sauce should look glossy and smell incredibly aromatic.

Step 3: Cook the Shrimp in the Sauce

Add the seasoned shrimp to the skillet in a single layer, if possible. Increase the heat to medium-high and cook for 2-3 minutes per side, basting the shrimp with the sauce frequently. You’ll know they’re done when they turn opaque and pink with a slight curl.

Don’t overcrowd the pan—if needed, cook the shrimp in batches. This ensures each piece gets properly coated in that amazing sauce and cooks evenly. The shrimp should finish cooking in about 6-8 minutes total.

Step 4: Finish and Serve with French Bread

Once the shrimp are cooked through, remove the skillet from heat. Let the shrimp sit in the sauce for 1-2 minutes to soak up even more flavor. Taste the sauce and adjust seasoning if needed—though I find it perfect with the given amounts.

Transfer everything to a large serving bowl or platter. Garnish with the 4 whole Green Onions, thinly sliced. Serve immediately with the 1 loaves French Bread on the side for dipping. The bread is non-negotiable—it’s essential for soaking up every last bit of that incredible sauce.

Flavor Customization for deanies seafood barbecue shrimp

Extra Spicy Kick

For heat lovers, I boost the cayenne pepper to 1 full teaspoon and add ½ tsp red pepper flakes to the sauce. A dash of Tabasco Scorpion instead of regular hot sauce adds serious fire. The butter balances the heat beautifully. 🌶️

Citrus Forward Twist

Add zest of 1 lemon with the juice for brighter flavor. I also love stirring in 1 tbsp orange juice at the end. The citrus lifts the richness of the butter without overpowering the peppery base.

Herb Infused Depth

Swap dried herbs for fresh: 1 tbsp chopped rosemary and 1 tbsp fresh thyme leaves. Add them with the garlic. Foraging wild rosemary along coastal rides adds a special touch I love.

Smoky Variation

Use smoked paprika instead of regular and add ½ tsp liquid smoke to the sauce. This gives a subtle BBQ pit flavor that reminds me of my family cookouts. The smoke pairs perfectly with the shrimp.

French Technique Upgrade

Deglaze the pan with ¼ cup dry white wine after cooking shrimp. Reduce by half before adding butter. This French technique I learned adds complexity—try Sauvignon Blanc for best results. 💫

Less Heat Option

Reduce cayenne to ¼ tsp and skip hot sauce. Add 1 tsp honey to balance the pepper. The dish stays flavorful but milder for sensitive palates.
