Grilled Butterfly Shrimp Recipe: Charred Edges and Bold Garlic Flavor

There’s nothing like the first scent of shrimp hitting a hot grill—it brings me back to those backyard cookouts. This method transforms simple shrimp into something extraordinary with just a few techniques.

Butterflying the shrimp ensures even cooking and maximum surface area for charring. A bold garlic marinade infuses every bite with depth, while high heat creates those coveted crispy edges.

The result is juicy, tender shrimp with a smoky char and layers of flavor. It’s a dish that feels special but comes together quickly with minimal effort.

Serve straight off the grill for the best experience. The charred edges and aromatic garlic will have everyone reaching for seconds.

Ingredients for Grilled Butterfly Shrimp

Fresh shrimp, bold marinade, and a hot grill are all you need.

The shrimp quality is non-negotiable for this dish. Wild-caught Gulf shrimp (16-20 count per pound) give the best texture and flavor. Buy them fresh from a trusted seafood counter—avoid the pre-frozen bags at the grocery store. If you must use frozen, thaw them slowly in the fridge overnight. Costco has surprisingly good shrimp if you’re feeding a crowd (the 21-25 count works too).

No honey? Maple syrup or agave works in a 1:1 swap. Out of Dijon? Whole-grain mustard at the same amount adds a nice texture. The olive oil can be any neutral oil in a pinch, but extra-virgin adds depth. If you don’t have fresh parsley, dried parsley at one-third the amount or cilantro makes a fine substitute.

Marinate the shrimp for no more than 2 hours—any longer and the acid in the lemon will start to cook them. Leftovers keep 2-3 days in the fridge. Reheat gently in a skillet or serve cold—both work well. The marinade can be made a day ahead for deeper flavor.

Step-by-Step Instructions for Grilled Butterfly Shrimp

Here is the method to achieve perfectly charred shrimp with bold garlic flavor.

Step 1: Butterfly and Season the Shrimp

Using kitchen shears, carefully cut the 1.5 lb Large Shrimp along the belly, stopping just before the tail, so they open like a book. Press gently to flatten slightly—this creates more surface area for grilling and even cooking.

Pat the shrimp completely dry with paper towels. Moisture prevents proper charring. Season both sides with 1 tsp Salt and 0.5 tsp Black Pepper, ensuring the seasoning adheres to the cut surfaces. This step builds the flavor foundation before marinating.

Step 2: Prepare the Garlic Marinade

In a large bowl, whisk together 0.25 cup Olive Oil, 2 tbsp Lemon Juice, 1 tbsp Dijon Mustard, 1 tbsp Honey, 6 cloves Garlic Cloves (minced), 1 tsp Paprika, and 0.25 tsp Cayenne Pepper until fully combined. The honey balances the acidity while the paprika and cayenne add depth.

Add the butterflied shrimp to the marinade, tossing gently to coat every surface. Let them marinate at room temperature for 15-20 minutes—long enough to absorb flavor but not so long that the acid starts to “cook” the shrimp.

Step 3: Grill to Charred Perfection

Preheat your grill to medium-high heat (about 400°F). Clean and oil the grates thoroughly to prevent sticking. Remove shrimp from the marinade, shaking off excess, and discard the marinade to avoid cross-contamination.

Place shrimp on the grill, cut-side down first, and cook undisturbed for 2-3 minutes until you see char marks forming. Flip carefully using tongs and cook for another 1-2 minutes until the shrimp turn opaque pink and the edges are slightly charred. The tails may curl slightly—that’s normal.

Step 4: Garnish and Serve Immediately

Transfer the grilled shrimp to a serving platter. Immediately sprinkle with 0.25 cup Fresh Parsley (chopped) for a bright, fresh contrast to the smoky char. The parsley also adds a pop of color that makes the dish look as good as it tastes.

Arrange 4 pieces Lemon Wedges around the platter for serving. The acid from the lemons cuts through the richness of the olive oil marinade. Serve while hot—the shrimp are best enjoyed fresh off the grill when the char is at its peak.
