Grilled Cajun Shrimp Foil Packets

Cajun Shrimp foil packets are simple to prepare and perfect for busy weeknights or summer grilling. Spicy shrimp tossed in Cajun seasoning are baked inside foil pouches with slices of Andouille-style sausage and colorful vegetables, producing a flavorful, low-fuss meal with minimal cleanup.

If you like easy foil packet dinners, try a fish taco–style packet for a different, Mexican-inspired flavor instead of shrimp.

Cajun Shrimp in Foil

This recipe combines bold Cajun flavor with tender shrimp, smoky sausage, and crisp-tender vegetables sealed in foil to trap steam and concentrate juices. It’s fast to assemble, can be prepped ahead and frozen, and bakes quickly in a hot oven. You can also adapt the method for an air fryer or a sheet-pan roast if you prefer.

This version is adapted from a recipe in Ellie Krieger’s cookbook You Have It Made — Delicious, Healthy, Do-ahead Meals. The technique of assembling packets in advance and freezing them makes weeknight dinners much easier.

Ingredients

• 1 tablespoon Cajun seasoning (or Creole seasoning)
• 1 pound large shrimp, peeled and deveined (about 24 shrimp)
• 3 ounces cooked turkey or chicken Andouille-style sausage, very thinly sliced
• 1 medium zucchini (about 8 ounces), sliced into 1/4-inch rounds
• 1 large red bell pepper, seeded and cut into thin strips
• 1 1/2 cups corn kernels (fresh, frozen, or canned and drained)
• 1/4 cup chopped fresh Italian parsley leaves
• 1/4 cup chopped fresh basil leaves
• 1/4 cup dry white wine (such as Pinot Grigio) or a splash of low-sodium chicken broth
• 2 tablespoons olive oil (about 1/2 tablespoon per packet)
• Salt and freshly ground black pepper, to taste

Instructions

1. Preheat the oven to 425°F (if cooking immediately). In a medium bowl, combine the Cajun seasoning with a pinch of salt and pepper. Add the shrimp and toss to coat evenly.
2. Lay out four large pieces of heavy-duty aluminum foil (about 10 x 18 inches each) on a flat surface.
3. Divide the sliced sausage, zucchini, red bell pepper, and corn evenly among the four foil pieces, placing the vegetables in the center of each piece of foil.
4. Top the vegetables in each packet with about six seasoned shrimp. Sprinkle each with 1 tablespoon chopped parsley and 1 tablespoon chopped basil.
5. Drizzle each packet with 1 tablespoon dry white wine (or broth) and about 1/2 tablespoon olive oil. Fold the foil to form a sealed packet, leaving a little air space so steam can circulate. If preparing ahead, refrigerate or freeze the sealed packets at this stage.
6. To bake fresh packets, place them on a rimmed baking sheet and bake at 425°F for about 13 minutes, or until the shrimp are cooked through and vegetables are crisp-tender. Open the packets carefully to avoid hot steam and transfer contents to plates or bowls, spooning any accumulated sauce over the shrimp and vegetables.

To freeze and reheat

1. Place uncooked, sealed packets upright in sealable plastic freezer bags (two packets fit well in a gallon-size bag). Freeze for up to two months. There’s no need to thaw before cooking.
2. Remove frozen packets from the bags and place them on a baking tray in a cold oven. Set the oven to 425°F.
3. Once the oven reaches temperature, bake the frozen packets for 35–40 minutes, until the shrimp and vegetables are cooked through. Open carefully and serve.

Tips, variations and serving suggestions

• Vegetable swaps: Use yellow squash, green beans, or cherry tomatoes instead of or in addition to zucchini and bell pepper.
• Protein swaps: Substitute firm fish fillets for shrimp (adjust cooking time) or use chicken pieces (ensure chicken reaches a safe internal temperature).
• Make it spicy: Add a pinch of cayenne or a few dashes of hot sauce to the seasoning mix for extra heat.
• Serving ideas: Serve packets over rice, couscous, or quinoa to soak up the juices, or enjoy with crusty bread and a simple green salad.
• Air fryer option: If using an air fryer, cook at 400°F for about 8–10 minutes, checking for doneness; timing will vary by model and packet thickness.
