Grilled Shrimp Foil Packets Recipe: Smoky Char With Zesty Garlic Butter

There’s nothing like the smoky aroma of shrimp grilling over open flames, sealed in foil to lock in every bit of flavor. This method delivers tender, perfectly cooked shrimp with minimal effort and maximum impact.

I developed this technique for summer cookouts, where the char from the grill and the zesty garlic butter create a combination that’s impossible to resist. The foil packets keep everything contained, making cleanup a breeze.

In just 15 minutes on the grill, you’ll have juicy shrimp infused with bold flavors. The foil traps steam to cook the shrimp gently while allowing the edges to caramelize.

Serve these packets straight from the grill for a meal that feels special but requires little work.

The shrimp is the star here. Look for large or jumbo shrimp (16-20 count per pound) at your seafood counter—fresh or frozen both work, just thaw frozen shrimp completely. Wild-caught from the Gulf or Pacific is ideal if available. I always buy mine from Whole Foods when they have a good selection, but most supermarkets carry quality frozen options. Avoid pre-cooked shrimp, as they’ll turn rubbery with the additional cooking time.

No Old Bay? A mix of celery salt, paprika, and cayenne gets you close. Fresh out of parsley? Cilantro or green onions add a nice fresh finish too. The andouille sausage can be swapped for smoked sausage or chorizo if you prefer a different flavor profile. For a lighter option, skip the sausage entirely and add more veggies like zucchini or bell peppers (tossed in olive oil first).

These packets are best served fresh off the grill, but leftovers keep well. Store cooked shrimp and veggies in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet or microwave. The garlic butter can be made ahead and stored in the fridge for up to 1 week.

Step-by-Step Instructions for Grilled Shrimp Foil Packets

Here’s the method. Straightforward, tested, works every time.

Step 1: Prep and Season the Ingredients

Tear off four large sheets of heavy-duty aluminum foil, about 18 inches each. Divide the 1.5 lb large shrimp, 2 whole ears of corn (husked and cut into thirds), 0.5 lb small red potatoes (sliced thin), and 0.5 lb andouille sausage (sliced into rounds) evenly among the foil sheets.

Drizzle each portion with 2 tbsp olive oil divided equally, then sprinkle with 1 tbsp Old Bay Seasoning, 1 tsp paprika, 0.5 tsp salt, and 0.5 tsp black pepper. Toss gently to coat everything evenly. The potatoes should glisten, and the spices should cling to all surfaces.

Step 2: Add Garlic Butter and Aromatics

In a small bowl, melt the 0.5 cup unsalted butter and stir in the 6 cloves minced garlic cloves and 0.25 tsp red pepper flakes. Spoon this mixture evenly over each foil packet, ensuring the shrimp and sausage are well-coated. The garlic should be fragrant, and the butter should pool slightly at the bottom.

Top each packet with a few slices of the 1 whole lemon and a sprinkle of the 0.25 cup chopped fresh parsley. The lemon slices will infuse the dish with brightness, while the parsley adds a fresh finish.

Step 3: Seal and Grill to Perfection

Fold the foil over the ingredients, crimping the edges tightly to create a sealed packet. This prevents any juices from escaping and ensures even cooking. The packets should be secure but not overly compressed—leave room for steam to circulate.

Place the packets on a preheated grill over medium-high heat (about 400°F). Cook for 12-15 minutes, flipping once halfway through. The packets are done when the shrimp turn opaque and pink, the potatoes are tender when pierced with a fork, and the sausage is heated through.

Step 4: Serve with Care

Carefully remove the packets from the grill using tongs, as they’ll be hot. Let them rest for 2-3 minutes to allow the steam to settle. Open the packets cautiously to avoid burns from the escaping steam.

Transfer the contents to plates, ensuring each serving includes shrimp, sausage, corn, and potatoes. Garnish with any remaining lemon slices and fresh parsley. The shrimp should have a slight char, the corn should be sweet and juicy, and the potatoes should be soft with crispy edges.

Perfect Pairings for This grilled shrimp foil packets

Beverage Pairings

A crisp Sauvignon Blanc from New Zealand cuts through the garlic butter beautifully. The citrus notes complement the lemon in the packets, and the acidity cleanses your palate between bites. I always keep a bottle of Cloudy Bay on hand for grilling season. 🍷

Beer Options

For beer lovers, a light wheat beer like Blue Moon or a citrusy IPA works wonders. The effervescence lifts the richness of the shrimp, while the hoppy notes balance the smoky char. Avoid heavy stouts—they’ll overpower the delicate seafood flavors.

Side Dish Ideas

A simple green salad with a tangy vinaigrette offers a fresh contrast to the hearty foil packets. I like tossing baby arugula with lemon juice and olive oil for a quick, bright side. The peppery greens stand up to the bold seasoning.

Bread Pairings

Warm crusty bread is perfect for soaking up the garlic butter sauce. I often grill slices of ciabatta alongside the packets for 2-3 minutes per side. The smoky char on the bread mirrors the flavors in the shrimp. 🔥

Vegetable Additions

If you want extra greens, serve with grilled asparagus or zucchini. Toss them in olive oil and a pinch of Old Bay Seasoning before grilling for 4-5 minutes. This keeps the meal cohesive with shared flavors.

Dessert Follow-Up

End with something light, like lemon sorbet or fresh berries. The citrus ties back to the garlic butter, while the sweetness balances the meal’s smoky, savory notes. I like serving strawberries macerated with a touch of balsamic glaze.
