Forget complicated side dishes. Foil packet potatoes deliver maximum flavor with minimal effort. This method creates tender, seasoned potatoes perfect for any barbecue or outdoor meal. Fire up the grill and get ready for the easiest potato recipe you’ll make all summer.
Why This Recipe Works
- The foil packet method steams the potatoes while allowing smoke to infuse them with barbecue flavor, creating perfectly tender potatoes with a subtle smokiness that complements any grilled main course.
- Using olive oil as the base coating ensures even cooking and helps the seasoning adhere to every potato piece, preventing dry spots and creating a consistent texture throughout the entire packet.
- Precise temperature control at 400°F guarantees thorough cooking without burning, while the 45-minute cook time allows potatoes to become fork-tender while developing a slightly crisp exterior where they touch the foil.
- The simple seasoning blend of garlic powder, paprika, salt, and pepper enhances natural potato flavor without overwhelming it, making these potatoes versatile enough to pair with any protein from steak to chicken to fish.
- Foil packet cooking contains all moisture and flavor within the sealed environment, resulting in potatoes that stay hot longer and require no additional cleanup beyond disposing of the foil.

Instructions
Prepare the Potatoes and Seasoning
Begin by scrubbing 2 pounds of russet potatoes under cold running water to remove any dirt or debris. Pat them completely dry with paper towels or a clean kitchen cloth. Using a sharp chef’s knife and stable cutting board, carefully cut each potato into uniform 1-inch cubes. Consistent sizing ensures even cooking throughout the packet. Place all potato cubes into a large mixing bowl. In a separate small bowl, combine 1 teaspoon garlic powder, 1 teaspoon smoked paprika, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Mix these dry seasonings thoroughly with a fork or small whisk to create an even distribution of flavors. This separate mixing step prevents clumping and guarantees each potato piece receives balanced seasoning. Tip: For extra crispy edges, ensure potatoes are completely dry before adding oil and seasonings.
Combine Potatoes with Oil and Seasonings
Pour 3 tablespoons of olive oil over the potato cubes in the large mixing bowl. Use your hands or a large spoon to toss the potatoes until every piece is lightly coated with oil. The oil creates a binding layer that helps the seasonings adhere and promotes even browning during cooking. Once the potatoes are evenly coated, sprinkle the pre-mixed seasoning blend over them. Continue tossing and stirring until all potato pieces display an even coating of the reddish-brown seasoning mixture. Take care to lift and fold the potatoes from the bottom of the bowl to ensure seasoning reaches every surface. The potatoes should appear uniformly colored with no visible dry spots. This thorough coating process typically takes 2-3 minutes of consistent tossing to achieve perfect distribution.
Assemble the Foil Packets
Tear off an 18-inch long piece of heavy-duty aluminum foil. Place the foil shiny side down on your work surface. Transfer all seasoned potato cubes to the center of the foil, arranging them in a single layer approximately 1-inch thick. Avoid piling potatoes too high, as this prevents even cooking. Bring the long sides of the foil together above the potatoes and fold them down in 1-inch increments until the foil rests snugly against the potato layer. Fold the short ends upward and inward, crimping them tightly to create a completely sealed packet. The finished packet should be airtight to trap steam during cooking. Test the seal by gently pressing on the packet – if air escapes, reinforce the folds. Tip: Double-layer the foil if using standard thickness to prevent tearing during handling.
Grill the Potato Packets
Preheat your grill to medium-high heat, achieving a consistent temperature of 400°F. Use an oven thermometer if your grill doesn’t have a built-in temperature gauge. Place the sealed foil packet directly on the grill grates and close the lid. Cook for 45 minutes, resisting the urge to open the lid frequently as this releases heat and steam essential for proper cooking. After 30 minutes, use tongs to carefully flip the entire packet to ensure even heat distribution. The packet will be hot, so use heat-resistant gloves or additional tongs for safety. Continue cooking for the remaining 15 minutes. The potatoes are done when they’re fork-tender and easily pierced through the foil with little resistance.
Serve and Garnish
Using tongs, carefully transfer the hot foil packet to a heat-safe surface or serving platter. Allow the packet to rest for 5 minutes before opening – this allows the potatoes to absorb any remaining steam and settle their texture. Use caution when opening the packet as hot steam will escape. Cut open the top of the foil with kitchen scissors or carefully peel back the folds. Transfer the cooked potatoes to a serving bowl using a spatula, scraping any crispy bits from the foil bottom. Sprinkle 2 tablespoons of chopped fresh parsley over the potatoes for color and fresh flavor. Serve immediately while hot. Tip: For extra flavor, sprinkle with grated Parmesan cheese or crispy bacon bits before serving.
Tips and Tricks
For optimal results, consider these additional techniques beyond the basic recipe. When selecting potatoes, russets work well for their starch content, but Yukon Gold potatoes offer a creamier texture with buttery flavor that complements the smoky grill notes. For maximum crispiness, arrange potato cubes in a single layer without overcrowding and consider spraying the foil with cooking spray before adding potatoes to prevent sticking. If cooking multiple packets, space them evenly on the grill with at least 2 inches between packets for proper air circulation and heat distribution. For enhanced smoke flavor, add wood chips to your grill – hickory or mesquite work particularly well with potatoes. When testing for doneness, insert a fork through the foil into the largest potato piece; it should slide in easily with no resistance. If potatoes need more time, reseal the packet and continue cooking in 5-minute increments. For meal prep, you can assemble packets up to 4 hours ahead and refrigerate until ready to grill. Leftover potatoes store well in airtight containers for 3-4 days and reheat beautifully in a skillet with a little oil to restore crispness. For larger crowds, double the recipe but use multiple smaller packets rather than one large packet to maintain even cooking. If your grill runs hot, reduce temperature to 375°F and extend cooking time to 55 minutes to prevent burning. For added depth, mix 1 tablespoon of Worcestershire sauce with the olive oil before coating potatoes. Always use heavy-duty foil to prevent tearing during flipping and handling. When serving, consider placing the entire opened packet on the table for a rustic presentation that keeps potatoes warm throughout the meal.
Recipe Variations
- Herb Garden Potatoes: Replace the paprika and garlic powder with 2 tablespoons of fresh chopped herbs. Use a combination of rosemary, thyme, and oregano for Mediterranean flavor. Add 1 minced garlic clove along with the herbs for fresh garlic notes that complement the herbal mixture. The fresh herbs create a brighter, garden-fresh profile that pairs well with grilled chicken or fish.
- Spicy Southwest Potatoes: Add 1 teaspoon chili powder, 1/2 teaspoon cumin, and 1/4 teaspoon cayenne pepper to the original seasoning mix. Include 1/4 cup diced red onion and 1/4 cup corn kernels with the potatoes before sealing the packet. Top with chopped cilantro instead of parsley after cooking. This variation brings Tex-Mex flavors that work perfectly with burgers or fajitas.
- Cheesy Bacon Potatoes: Mix 1 cup shredded cheddar cheese and 1/2 cup cooked crumbled bacon with the seasoned potatoes before sealing the foil packet. The cheese melts into creamy pockets while the bacon adds smoky saltiness. Use Monterey Jack cheese for milder flavor or pepper jack for spicy kick. This rich version becomes a standalone dish rather than just a side.
- Lemon Herb Potatoes: Add the zest of one lemon to the seasoning mixture and substitute parsley with fresh dill. Squeeze half the lemon’s juice over the potatoes before sealing the packet. The citrus brightens the potatoes and cuts through the richness of grilled meats. This variation works particularly well with seafood mains or Greek-inspired menus.
- Loaded Potato Style: After cooking, open the packet and top with sour cream, chopped chives, additional bacon bits, and more shredded cheese. Return to the grill for 2-3 minutes to melt the cheese. This creates a fully-loaded potato experience in convenient foil packet form, eliminating the need for individual potato preparation.
Frequently Asked Questions
Can I bake these potatoes in the oven instead of grilling?
Yes, oven baking works well for this recipe. Preheat your oven to 400°F and place the sealed foil packet on a baking sheet. Bake for 45-50 minutes, flipping the packet halfway through cooking. The results will be similar though you’ll miss the smoky grill flavor. For oven preparation, consider adding a teaspoon of liquid smoke to the seasoning mixture to approximate the grilled taste. The baking sheet catches any potential leaks and makes handling easier. Oven baking provides consistent results regardless of weather conditions, making this a reliable year-round option when grilling isn’t practical.
How do I know when the potatoes are fully cooked?
The potatoes are done when they’re easily pierced with a fork through the foil with no resistance. Insert the fork into the center of the packet where the largest potato pieces are located. Properly cooked potatoes should feel tender but not mushy, maintaining their cube shape while offering no crunch when tasted. If uncertain, carefully open one corner of the foil packet and test a potato piece directly. Under-cooked potatoes will be firm and crunchy in the center, while over-cooked potatoes may begin to disintegrate. The 45-minute cooking time at 400°F is reliable for 1-inch cubes, but actual time may vary slightly based on your grill’s heat distribution and potato freshness.
Can I prepare the foil packets ahead of time?
Yes, you can assemble the packets up to 4 hours in advance and refrigerate them until ready to cook. Keep them in the refrigerator until just before grilling to maintain food safety. The salt in the seasoning may draw out some moisture from the potatoes during storage, which can actually enhance the steaming process. If preparing more than 4 hours ahead, wait to add salt until just before cooking. For best results, bring refrigerated packets to room temperature for 15-20 minutes before grilling to ensure even cooking. This make-ahead option makes these potatoes ideal for entertaining when you want to minimize last-minute preparation.
What type of potatoes works best for this recipe?
Russet potatoes are ideal for their high starch content, which creates fluffy interiors and crisp exteriors. Yukon Gold potatoes offer a creamier, buttery texture that holds its shape well. Red potatoes provide waxier texture that maintains firmness, suitable if you prefer less fluffy results. Avoid using new potatoes or fingerlings unless cut to appropriate size, as their varying densities can lead to uneven cooking. For mixed texture, combine russet and Yukon Gold potatoes in equal parts. The potato variety significantly affects the final dish, so choose based on your texture preference – fluffy versus creamy versus firm.
Can I add other vegetables to the foil packet?
Absolutely, many vegetables complement potatoes in foil packets. Onions and bell peppers work particularly well, adding sweetness and color. Cut them into 1-inch pieces to match the potato cooking time. Carrots require thinner slicing or par-cooking as they take longer to soften. Zucchini and summer squash should be added in the last 15 minutes of cooking to prevent mushiness. Corn kernels, green beans, and broccoli florets all work with adjusted timing. When adding multiple vegetables, consider their cooking times and either pre-cook slower-cooking vegetables or add quicker-cooking ones later in the process. The liquid released from additional vegetables will create more steam, potentially reducing cooking time slightly.
Summary
Foil packet potatoes deliver perfectly cooked, flavorful potatoes with minimal effort and cleanup. The sealed environment steams potatoes to tenderness while allowing grill smoke to infuse flavor. This versatile method adapts to various seasonings and additions, making it suitable for any outdoor meal or indoor oven preparation.
