The potatoes are the foundation—Yukon Golds hold their shape while absorbing flavors. Whole Foods or Trader Joe’s carry quality organic options. For the vegan butter, Miyoko’s or Earth Balance melt beautifully and brown like dairy. Fresh herbs are non-negotiable here; dried won’t deliver the same aromatic punch. Look for rosemary and thyme with vibrant color and no wilting.

No Yukon Golds? Red potatoes work in a pinch (just don’t peel them). Out of fresh herbs? Dried at one-third the amount, but toast them first in a dry pan. Vegan butter can be swapped for extra-virgin olive oil, though the flavor profile shifts slightly. Smoked paprika is key for that grill flavor—don’t skip it. No lemon? A splash of apple cider vinegar adds similar brightness.

Prep the potatoes up to 8 hours ahead—keep them submerged in cold water to prevent browning. Cooked packets stay warm for 30 minutes off the grill. Leftovers? Unlikely, but they’ll keep in the fridge for 3-4 days. Reheat in a skillet to revive the crisp edges.

Step-by-Step Instructions for Grill Potatoes in Foil

Here’s the method. Straightforward, tested, works every time.

Step 1: Prepare and Season the Potatoes

Scrub the 2 lb Yukon Gold Potatoes thoroughly and cut them into 1-inch cubes. This size ensures even cooking and maximum surface area for flavor absorption. Place the cubes in a large bowl.

Drizzle the 2 tbsp Olive Oil over the potatoes and toss to coat evenly. Add the 1 tsp Sea Salt, 0.5 tsp Black Pepper, 1 tsp Smoked Paprika, and 1 tsp Onion Powder. Toss again until every cube is uniformly seasoned. The smoked paprika is what gives these potatoes their signature depth.

Step 2: Create the Aromatic Butter Mixture

In a small bowl, melt the 0.5 cup Vegan Butter if it isn’t already liquid. Stir in the 6 cloves minced Garlic Cloves, 2 tbsp Fresh Rosemary, 1 tbsp Fresh Thyme, and 1 tbsp Lemon Juice. The acid from the lemon juice brightens the rich butter and herbs.

This mixture should be fragrant with the herbs and garlic fully suspended in the butter. The combination of rosemary and thyme creates a classic herb profile that pairs perfectly with the smoky paprika.

Step 3: Assemble the Foil Packets

Lay out the 4 sheets Aluminum Foil and divide the seasoned potatoes evenly among them. Drizzle each portion with the garlic butter mixture, dividing it equally. I use heavy-duty foil for durability—it holds up better to the grill’s heat and makes flipping easier.

Fold the foil over the potatoes to create sealed packets. Crimp the edges tightly to prevent any juices from leaking out during grilling. These packets will steam the potatoes from within while allowing them to absorb all that garlicky, herby goodness.

Step 4: Grill to Perfection

Preheat your grill to medium-high heat (about 400°F). Place the foil packets directly on the grates and cook for 25-30 minutes, flipping once halfway through. The packets should be slightly puffed when done.

Carefully open one packet to check for doneness. The potatoes should be tender when pierced with a fork and have absorbed most of the liquid. If they need more time, reseal the packet and return to the grill for another 5 minutes.

Garlic Aioli Drizzle

Whisk ½ cup vegan mayo with 2 minced garlic cloves, 1 tbsp lemon juice, and ½ tsp smoked paprika. This creamy, tangy sauce complements the smoky potatoes beautifully. I like Hellmann’s Vegan for its rich texture. 💛

Chimichurri Sauce

Blend 1 cup fresh parsley, ¼ cup olive oil, 2 tbsp red wine vinegar, and 1 minced garlic clove. The bright, herby flavors cut through the richness of the dish. Use a food processor for smooth consistency.

Spicy Ketchup

Mix ½ cup ketchup with 1 tsp sriracha and ½ tsp smoked paprika. This adds a sweet-heat kick that pairs perfectly with the garlic butter. I prefer Heinz Organic for its clean flavor.

Combine ½ cup coconut yogurt with 1 tbsp lemon zest, 1 tsp chopped fresh rosemary, and salt to taste. The cool, tangy sauce balances the smoky warmth of the potatoes.

Use So Delicious or Kite Hill for the best texture. 🍋

Smoky BBQ Glaze

Simmer ½ cup BBQ sauce with 1 tsp liquid smoke and 1 tbsp maple syrup for 5 minutes. Brush this over the potatoes before serving for extra depth. Stubb’s Original works great here.
