Hearty Foil Packet Garlic Butter Shrimp

The Butter Problem—Solved

Butter burns at around 250°F. Inside a foil packet on hot coals, the temperature can climb higher. The solution is twofold. First, cut the butter into small pieces (about ½ tablespoon each) and distribute them on top of the shrimp. This lets the butter melt gradually rather than pooling and scorching. Second, add a squeeze of lemon juice. The acidity raises the smoke point of the butter slightly and adds a bright note that cuts through the richness.

Do not use margarine or spreadable butter substitutes—they contain water and can make the shrimp watery. Real unsalted butter gives the best flavor and texture.

Seasoning That Stays Put

Minced garlic, smoked paprika, a pinch of red pepper flakes, salt, and pepper. Mix these in a small bowl before you leave home. At the campsite, sprinkle the dry mix over the shrimp before adding the butter and lemon. The fat from the butter carries the seasoning into every bite. Smoked paprika is not traditional, but it adds a subtle campfire note that matches the cooking method.

Common Mistake: Opening Too Early

Resist the urge to peek. Every time you open a packet, steam escapes and cooking slows down. Trust the 10-minute mark. If your shrimp are smaller (31-40 count), check at 8 minutes. Jumbo shrimp (16-20 count) may need 14 minutes. Let the packet rest for 1 minute after opening—the shrimp continues to cook from residual heat.

Serving and Variations

Serve straight from the foil with crusty bread to soak up the garlic butter. Or spoon over quick-cook rice or couscous. For a low-carb option, serve with sautéed zucchini or a simple green salad.

To make it a complete meal packet, add thinly sliced zucchini, cherry tomatoes, or asparagus along with the shrimp. Keep vegetable pieces about ¼ inch thick so they cook in the same window. Avoid raw potatoes, carrots, or other dense vegetables—they need much longer to cook and will leave you with underdone veggies and overdone shrimp.

Make-Ahead Prep

Combine the dry spices at home. Portion the butter into small pieces and keep in a small container in the cooler. Keep the shrimp in a sealed bag on ice. At the campsite, assemble the packets in 5 minutes. This is the fastest way to get dinner on the table after a long day of hiking.
