What Are Grilled Scalloped Potatoes?
Grilled Scalloped Potatoes stem from the classic scalloped potato dish but are cooked on the grill, giving them a delightful twist. Traditionally, scalloped potatoes consist of thinly sliced potatoes layered in cream and cheese, baked until bubbly. The grilled version retains all those creamy elements but introduces a subtle smokiness that makes each bite unforgettable.
The taste is a heavenly blend of tender, thinly sliced potatoes infused with rich, velvety cream and perfectly caramelized onions. The texture is soft and creamy inside, while the edges develop a slight crispness from the grill. What makes these unique is the grilling technique; it adds an element of fun and festivity that traditional oven baking just can’t replicate. Grilled Scalloped Potatoes are perfect for summer cookouts, family gatherings, or even a cozy weeknight dinner on the porch.

Ingredients

- 1 1/2 tbsp unsalted butter: Make sure it’s at room temperature for easy greasing.
- 2 lb potatoes, peeled and sliced into 1/8-inch rounds: Opt for Yukon Gold or Russet for their creamy texture and flavor.
- 1 medium onion, thinly sliced into half-moons: Sweet onions work great here!
- 2 1/2 tsp fresh thyme: Fresh is key, but dried thyme can be used in a pinch.
- Salt and black pepper: Season to taste.
- 3/4 cup heavy cream: Look for high-quality cream for the best richness.
- 1/3 cup broth: Vegetable or chicken broth can be used interchangeably.
- 1/2 tsp garlic powder: Adds a wonderful depth of flavor.
Notes: Use organic ingredients where possible for the best flavor, and if you’re looking to make this dish dairy-free, coconut cream and vegetable broth can be fantastic substitutes.

Step-by-Step Instructions
Prep the Ingredients:
- Start by peeling the potatoes and slicing them into thin 1/8-inch rounds. A mandoline slicer is excellent for achieving uniform slices.
- Thinly slice the onion into half-moons, and measure out your fresh thyme. Having everything ready makes the assembly a breeze!
Heat the Grill:
- Preheat your grill to 375 degrees F. Make sure to clean the grill grates for that perfect non-stick experience.
Grease Your Skillet:
- Take a cast-iron skillet or a grill-safe baking dish and grease it generously with room temperature unsalted butter.
Layer the Ingredients:
- Now, it’s time to build the layers! Begin with 1/3 of the sliced potatoes, followed by 1/3 of the sliced onions, and 3/4 tsp of thyme. Season with a sprinkle of salt and pepper.
- Repeat this layering process two more times, finishing with a layer of potatoes on top.
Prepare the Cream Mixture:
- In a bowl, whisk together the heavy cream, broth, and garlic powder. This luscious mixture will be the glue that brings everything together.
Combine and Grill:
- Pour the cream mixture over the layers, ensuring everything is well coated.
- Cover the skillet tightly with aluminum foil, which will help everything cook evenly.
Grill to Perfection:
- Place the covered skillet on the grill and cook for 30 to 40 minutes. Begin checking for doneness at the 30-minute mark—the potatoes should be fork-tender.
Finishing Touches:
- Once tender, remove the skillet from the grill and let it rest, uncovered, for 10 minutes before serving. This allows it to set slightly, making it easier to serve.
Chef’s Tips:
- If you want to add cheese, sprinkle some on top during the last 5 minutes of cooking for a beautiful melty layer.
- Avoid lifting the foil during cooking to maintain a stable temperature for even cooking.
Expert Tips & Tricks
Storage Recommendations: Leftover Grilled Scalloped Potatoes can be stored in an airtight container in the fridge for up to 3 days. They are just as delicious reheated the next day!
Make-Ahead Instructions: You can prepare the layers a day in advance, cover them well, and then pour the cream mixture just before grilling.
Troubleshooting: If your potatoes are browning too quickly, lower the grill temperature or move the skillet to a cooler spot on the grill.
Flavor Boost: For an extra depth of flavor, consider adding parmesan cheese to the cream mixture or bacon bits between the layers!
Patience Is Key: If you’re eager to dig in, resist the urge to skip the resting period. This step allows the flavors to meld perfectly and gives you a creamier dish.

Grilled Scalloped Potatoes pair well with many grilled meats! Try serving alongside grilled chicken, steak, or even veggie skewers for a delightful cookout spread.
