Ingredients for Garlic Butter Shrimp in Foil Packets

- 4 cloves garlic
- 1 lemon
- 1 tsp paprika

- Black pepper to taste
Use peeled and deveined large shrimp for the easiest preparation, and thaw frozen shrimp completely before cooking. Pat the shrimp dry so the butter sauce is not diluted. The exact ingredient list is: 1 lb large shrimp; 4 tbsp butter; 4 cloves garlic; 1 lemon; 1 tsp paprika; 1 tsp Italian seasoning; Salt to taste; Black pepper to taste.
How to Make Garlic Butter Shrimp in Foil Packets
Step 1: Heat the Oven
Set an oven rack in the center position and heat the oven to 400°F. If you are using a grill instead, preheat it to medium-high heat, about 400°F, and plan to cook the packets with the lid closed. Line a rimmed baking sheet with foil or parchment to catch any butter that escapes from the packets.
Step 2: Prepare the Shrimp
If the shrimp are frozen, thaw them in the refrigerator overnight or place them in a sealed bag in cold water until thawed. Drain and pat them dry with paper towels. Remove the shells and tails if needed, then check that the dark vein along the back has been removed. Keep raw shrimp separate from ready-to-eat foods, and wash your hands, cutting board, and utensils with hot, soapy water after handling them.
Step 3: Make the Garlic Butter
Melt the butter in a small saucepan over low heat or in a microwave-safe bowl in short intervals. Stir in the finely minced garlic, paprika, Italian seasoning, salt, and black pepper. Zest half of the lemon into the butter if you want a stronger lemon flavor, then cut the lemon into wedges. Do not add all of the lemon juice yet; adding it after cooking keeps the sauce bright and prevents the packets from becoming too watery.
Step 4: Build the Packets
Tear off two large sheets of heavy-duty foil, or use two layers of regular foil for each packet. Divide the shrimp between the sheets and fold the foil edges upward to make a shallow bowl. Spoon the garlic butter over the shrimp and toss gently so the pieces are coated. Fold the foil over the top and crimp the edges tightly, leaving a little room inside for steam. Set the packets seam-side up on the prepared baking sheet.
Step 5: Cook the Shrimp
Bake the packets at 400°F for 8 to 10 minutes, depending on the size of the shrimp and how crowded the packets are. Large shrimp are done when they are opaque throughout, firm but not hard, and curled into a loose C shape. For a food-safety check, the thickest shrimp should reach 145°F on an instant-read thermometer. On a covered medium-high grill, cook the packets for about 8 to 10 minutes, turning them once if the grill heats unevenly.
Step 6: Finish and Serve
Let the packets rest for 1 to 2 minutes, then open them carefully away from your face because hot steam will escape. Squeeze fresh lemon juice over the shrimp and taste the sauce for seasoning. Serve immediately with the buttery juices. Refrigerate leftovers in a shallow covered container within 2 hours, and use them within 3 to 4 days. Reheat gently just until hot so the shrimp do not become rubbery.
Tips for Success
- Do not overcook the shrimp. They continue cooking briefly from the retained heat inside the packet, so check them at the lower end of the cooking time.
- Use heavy-duty foil or a double layer of regular foil to reduce the chance of tearing when you move the packets.
- Leave a little air space inside each packet. A snug seal helps the shrimp steam, while a crowded packet can cook unevenly.
- Add lemon juice after the packets are opened for a cleaner, fresher flavor and a sauce that is less watery.
- If you prepare the packets ahead, refrigerate them promptly and cook them within the same day. Do not leave raw shrimp at room temperature.
Equipment Needed
- Rimmed baking sheet
- Small saucepan or microwave-safe bowl
- Instant-read thermometer
Variations
- Add thinly sliced bell pepper, zucchini, or asparagus to each packet, but cut the vegetables small enough to cook in about 10 minutes.
- Replace half of the Italian seasoning with dried oregano for a more herb-forward version while keeping the required seasoning in the recipe.
- Serve the cooked shrimp over cooked rice or pasta and spoon the lemon-garlic butter from the packet over the top.
- For a milder dish, use less black pepper and omit any extra red pepper flakes; the listed paprika provides gentle warmth without making the shrimp spicy.
- For grill cooking, use heavy-duty foil and place the packets over indirect heat if the butter begins to leak or the bottoms brown too quickly.
Serving Suggestions
Serve the shrimp as soon as they are finished, with lemon wedges and the garlic butter collected in the bottom of each packet. For a complete meal, pair them with rice, couscous, pasta, or toasted bread to catch the sauce. A simple green salad or steamed vegetable makes a useful side without competing with the shrimp. If serving as an appetizer, place the shrimp on a platter and provide small pieces of bread for dipping. Keep the shrimp hot while serving, and do not leave them at room temperature for more than 2 hours.
FAQs about Garlic Butter Shrimp in Foil Packets
Can I use frozen shrimp for garlic butter shrimp in foil packets? Yes, but thaw the shrimp fully before making the packets. Frozen shrimp release extra water and may cook unevenly if placed directly into the foil. Thaw them in the refrigerator or in a sealed bag set in cold water, then drain and pat them dry.
Should I leave the shrimp tails on? You can leave the tails on for appearance and a little extra flavor, or remove them for easier eating. The cooking time is the same as long as the shrimp are similar in size and arranged in an even layer.
How do I know when the shrimp are done? The shrimp should be opaque throughout, firm, and curled into a loose C shape. They should reach 145°F in the thickest part for food safety. Avoid cooking until they form a tight O shape, since that usually means they have become overcooked.
Can I make the foil packets ahead of time? You can assemble the packets several hours ahead and refrigerate them, covered, until cooking time. Keep them cold until they go into the oven or onto the grill, and cook them within the same day. Add the fresh lemon juice after cooking.
Can I reheat leftover foil-packet shrimp? Yes. Transfer the shrimp and sauce to a covered skillet or microwave-safe dish and heat gently just until hot. Refrigerate leftovers within 2 hours and use them within 3 to 4 days. Avoid high heat and long reheating because shrimp can turn tough.
Final Thoughts
These garlic butter shrimp foil packets make a dependable dinner when you want something quick, flavorful, and easy to clean up.
