Pellet Grill Seafood Foil Pack with Vegetables

Pellet Grill Seafood Foil Pack Guide

Nothing ruins a dinner like shrimp that feel like rubber bands or zucchini that turns into mush. I spent way too many weekends fighting with open grill grates, only to have my scallops stick or my vegetables dry out while the shrimp overcooked.

It's a frustrating cycle of trying to time three different proteins and sides on one hot surface.

The fix is putting everything in a pouch. By using a Pellet Grill Seafood Foil Pack, you create a mini steamer that locks in the juices and lets the smoke penetrate without drying out the delicate meat. You get that outdoor charred flavor but the tenderness of a poached dish.

Expect a meal that is buttery and bright. We use a mix of shrimp and scallops paired with quick cooking veg so that everything hits the right texture at the exact same time.

Why This Recipe Wins

• Steam Trap: The foil seals in moisture, so the seafood poaches in butter rather than searing dry.
• Smoke Infusion: The pellet grill adds a subtle wood flavor that you can't get from a standard stovetop.
• Unified Timing: Cutting the scallops and zucchini into similar sizes ensures nothing is raw while other bits are overdone.

Ingredient Role Breakdown

The Grocery List

• 1 lb large shrimp, peeled and deveined Why this? Large shrimp hold up better to heat.
• 1 lb sea scallops, cut into 1 inch chunks Why this? Uniform size prevents overcooking.
• 4 tbsp unsalted butter, cubed Why this? Cubes melt slowly for a steady baste.
• 1 cup zucchini, sliced into half moons Why this? Fast cooking time matches the shrimp.
• 1 cup red bell pepper, diced Why this? Adds a bright, sweet crunch.
• 1/2 cup corn kernels Why this? Adds sweetness and pops of texture.
• 2 cloves garlic, minced Why this? Fresh garlic beats powder here.
• 1 tbsp lemon juice, fresh Why this? Brightens the heavy butter.
• 1 tsp smoked paprika Why this? Complements the pellet smoke.
• 1 tsp Old Bay seasoning Why this? Classic seafood brine flavor.
• 1/2 tsp kosher salt Why this? Controls the seasoning levels.
• 1/4 tsp cracked black pepper Why this? Adds a mild heat.
• 1 lemon, sliced into rounds Why this? Infuses flavor while steaming.

Essential Kitchen Tools

You don't need a professional setup for this. A large mixing bowl is the main requirement to get the seafood coated. Most importantly, use heavy duty aluminum foil. Thin foil often tears when you're sealing the pouch, and a leak means your butter sauce escapes onto the grates, which can cause flare ups.

I recommend a pair of heat resistant gloves. These packets get incredibly hot and hold a lot of steam inside. When you open them, that first burst of vapor can be intense.

Cooking step by step

1. Preheat the pellet grill to 375°F (190°C). Note: This temp is high enough to steam the veg but low enough to avoid toughening the shrimp.
2. Tear off four large sheets of heavy duty aluminum foil, approximately 12x18 inches each.
3. In a large mixing bowl, toss the shrimp, scallops, zucchini, red bell pepper, and corn kernels with melted butter, lemon juice, smoked paprika, Old Bay seasoning, salt, and black pepper.
4. Divide the seafood and vegetable mixture evenly among the four foil sheets. Top each portion with a lemon slice and a pat of cubed butter.
5. Fold the sides of the foil up and over the ingredients, sealing the edges tightly to create a pouch. Note: Leave a small pocket of air inside for steam circulation.
6. Place the packets directly on the grill grates and grill for 12 to 15 minutes.
7. Gently shake the packets halfway through the cooking time to redistribute the butter.
8. Remove from heat when shrimp are opaque and the fish flakes easily with a fork.

According to guidelines on Serious Eats, seafood is done when it just turns opaque. Overcooking by even two minutes can make shrimp snap like rubber.

Fixing Common Issues

Troubleshooting Common Issues

Easy Ingredient Swaps

If you want to change the protein, you can easily swap the scallops for chunks of firm white fish. For a different vibe, try my Smoked Scallops recipe if you prefer them without the veg. If you're craving something richer, a Pellet Grill Salmon filet works well in a similar pouch, though you may need to add 3-5 minutes to the cook time.

For a low carb version, simply swap the corn for diced cauliflower. The cauliflower absorbs the butter and lemon juice just as well as the corn does.

Chef's Tip: If you want a deeper flavor, add a pinch of espresso powder to the seasoning mix. It doesn't make it taste like coffee, but it adds a dark, earthy note that pairs well with smoked paprika.

Adjusting Serving Sizes

Scaling Down

If you're cooking for two, use two sheets of foil and half the ingredients. Reduce the grill time by about 20% (roughly 10-12 minutes) since the smaller volume of food heats through faster.

Scaling Up

When making these for a crowd, work in batches. Don't overcrowd the grill, or the air won't circulate, and the packets in the middle will stay raw. For the spices, only increase them to 1.5x even if you're doubling the food, as Old Bay can become overpowering in large quantities.

Seafood Truths

Some people think you need to sear seafood first to "lock in juices." This isn't actually how it works. Moisture loss happens regardless of the sear. The crust from searing adds flavor, but in a Pellet Grill Seafood Foil Pack, we're going for a steamed, buttery texture instead.

Another myth is that you should soak scallops in milk first. While some do this to remove "fishiness," it can actually make the texture too soft. Fresh, high-quality scallops don't need this step.

Storing Your Seafood

You can store these in the fridge for up to 2 days. Keep them in an airtight container rather than leaving them in the foil, which can sometimes impart a metallic taste over time.

For freezing, I don't recommend freezing the cooked pouches. Seafood changes texture significantly when frozen and thawed, often becoming grainy. It's better to freeze the raw, seasoned mix in a vacuum seal bag and grill it fresh.

To reuse scraps, save the lemon rinds and any leftover zucchini ends. You can toss them into a freezer bag to make a quick vegetable stock later.

How To Serve

These are best served immediately. I love sliding the contents of the foil straight into a shallow bowl. The butter creates a natural sauce that is great for dipping crusty sourdough bread.

For a full meal, pair this with a side of jasmine rice or quinoa to soak up the lemon butter sauce. A crisp green salad with a light vinaigrette helps balance the richness of the butter.

The final touch is a sprinkle of fresh parsley or chives right before serving. It adds a pop of color and a fresh, herbal note that cuts through the smoke.

When checking the nutritional side, USDA FoodData shows that shrimp is a lean protein, so the majority of the calories in this Pellet Grill Seafood Foil Pack come from the butter. If you're watching fats, you can swap two tablespoons of butter for olive oil without losing the moisture.

Right then, you're ready to hit the grill. Just remember to keep that seal tight, and you'll have a meal that's tender, smoky, and ready in under 30 minutes.
