There’s nothing like the aroma of shrimp hitting a hot grill, especially when it’s wrapped in foil with zesty garlic butter. This method locks in moisture and flavor, ensuring every bite is tender and packed with bold taste.
I developed this technique for summer gatherings, where quick prep and easy cleanup are essential. The foil creates a steaming environment that cooks the shrimp evenly while the garlic butter infuses every piece with rich, savory notes.
The result is juicy shrimp with a subtle char, ready in 15 minutes. No special equipment needed—just a grill, foil, and a handful of fresh ingredients.
Perfect for feeding a crowd or a simple weeknight dinner. Here’s how to make it.

The shrimp is the star, so splurge on wild-caught or high-quality frozen—look for 16/20 count (that’s 16-20 shrimp per pound) for even cooking. Costco has great frozen options, or hit up a local seafood market for fresh. The garlic butter base needs real butter (no margarine) for that rich, creamy texture that clings to every shrimp. Don’t skimp on the Old Bay—it’s the signature flavor here.
No fresh parsley? Dried at one-third the amount works, but it won’t have the same bright pop. Out of lemons? Lime juice and zest can substitute in a pinch. If you’re avoiding alcohol, swap the white wine for seafood or vegetable stock. For extra richness, add a splash of melted butter right before serving. The foil is non-negotiable—heavy-duty only, or double up regular foil to prevent tears.
Assemble packets just before grilling—shrimp can sit in the garlic butter for 10 minutes max (or it’ll start to cook in the acid). Leftovers keep 2-3 days in the fridge, but they’re best fresh off the grill. Not a fan of tails? Remove them before serving for easier eating (just know they add flavor during cooking).

Step-by-Step Instructions for Garlic Butter Grilled Shrimp Foil Packets
Master this technique for perfectly cooked shrimp with bold, zesty flavor every time.
Step 1: Prepare the Shrimp and Seasonings
Begin by prepping the 1.5 lb large shrimp—ensure they’re peeled and deveined. In a large bowl, toss them with 1 tablespoon olive oil, 2 teaspoons Old Bay seasoning, 1 teaspoon salt, ½ teaspoon black pepper, and ½ teaspoon red pepper flakes.
This seasoning blend creates a robust base that enhances the shrimp’s natural sweetness. Make sure each piece is evenly coated so every bite delivers consistent flavor. The olive oil helps the spices adhere and prevents sticking during grilling.
Step 2: Create the Garlic Butter Mixture
In a small bowl, melt the ½ cup unsalted butter and combine it with the minced 6 cloves garlic cloves. Stir in the zest and juice from the 1 whole fresh lemon, which adds a bright, citrusy punch to balance the richness of the butter.
This mixture will infuse the shrimp with deep, aromatic flavor as it grills. The acidity from the lemon also helps tenderize the shrimp, ensuring they stay juicy. Let the garlic steep in the warm butter for 2-3 minutes to intensify the flavor before using.
Step 3: Assemble the Foil Packets
Tear the 1 sheet heavy-duty aluminum foil into four large squares, roughly 12×12 inches each. Divide the seasoned shrimp evenly among the foil squares, then drizzle each portion with the garlic butter mixture.
For extra depth, add ¼ cup dry white wine evenly across the packets. The wine will steam the shrimp, enhancing their flavor and keeping them moist. Fold the edges of the foil inward and seal tightly to create a secure packet that traps all the aromas inside.
Step 4: Grill to Perfection
Preheat your grill to medium-high heat (around 400°F). Place the foil packets directly on the grates and cook for 8-10 minutes, flipping once halfway through. The shrimp are done when they turn opaque and pink with a slight curl.
Avoid opening the packets early—this releases the steam and can dry out the shrimp. The foil ensures even cooking and locks in the zesty garlic butter flavor. If using a thicker cut or larger shrimp, extend the cooking time by 1-2 minutes.
Step 5: Garnish and Serve
Carefully open the packets (watch for steam!) and transfer the shrimp to a serving platter. Sprinkle with the chopped ¼ cup fresh parsley for a pop of color and freshness. The parsley adds a vibrant finish that complements the rich, garlicky butter sauce.
Serve immediately with the remaining sauce from the packets spooned over the top. Each bite should deliver tender shrimp infused with bold, zesty garlic butter flavor. Pair with crusty bread to soak up every last drop of the delicious sauce.
Pro Tips For Making Grilled Shrimp Foil
- Preheat the Foil: Throw your foil packet on the grill for 2-3 minutes before adding shrimp—it jumpstarts the cooking and prevents the butter from seizing up on cold metal.
- Dry the Shrimp: Pat those shrimp bone dry with paper towels first, or they’ll steam instead of sear in the butter and garlic. I learned this the hard way after three soggy batches.
- Skip the Overcrowd: Give each shrimp its own little space in the foil—pack them too tight and they’ll poach in their own juices instead of grilling. Sounds obvious, but it’s the easiest mistake to make.
- Zest Before Juicing: Grate the lemon zest directly over the shrimp before squeezing the juice—it adds a brighter, more intense citrus pop. My grandmother swore by this, and she was right.
