Whether you’re serving grilled steak, smoked brisket, barbecue chicken, or holiday roasts, these creamy scalloped potatoes are guaranteed to become a family favorite.

The Inspiration

Scalloped potatoes have long been a staple of comfort food, known for their tender layers of potatoes baked in a creamy, cheesy sauce. Traditionally prepared in the oven, this version embraces outdoor cooking by using the barbecue to create a subtle smoky flavor that perfectly complements the rich dairy and fragrant herbs.

Maddie and Kiki Longo showcase how everyday side dishes can become extraordinary with live-fire cooking. The combination of cheddar, Parmesan, and cottage cheese creates a velvety, flavorful sauce that coats every slice of potato, while fresh rosemary and thyme add earthy aromas that enhance the barbecue experience. The result is a comforting side dish that’s equally suited for backyard cookouts, holiday dinners, and family gatherings.

Ingredients

2 ½ pounds baking potatoes, peeled and sliced into 1/8-inch rounds (mandolin)
1 large white onion, thinly sliced
¼ cup salted butter, melted
½ cup cheddar cheese, shredded
½ cup Parmesan, grated
½ cup cottage cheese
1 tbsp fresh rosemary, chopped
1 tbsp fresh thyme, chopped
½ cup whipping cream
½ cup whole milk
Salt and ground black pepper, to taste

Method

Prepare the potatoes and place into a large container with cold water to prevent from oxidizing/browning.
In a large mixing bowl, whisk together melted butter, cheddar cheese, Parmesan, cottage cheese, milk, cream, thyme and rosemary.
Strain potatoes and pat dry thoroughly.
Add potato slices and onion to the cream mixture and fold in.
Season with salt and pepper.
Pour mixture into a 9×13 inch greased baking dish.
Tap the baking dish on the table a couple times to flatten and remove any air.
Cover with a sheet of parchment paper and a sheet of aluminum foil.
Preheat the barbecue to medium-high heat 350F.
Place the baking dish over direct heat for 45 minutes.
Remove aluminum foil and parchment paper and cook for another 15 minutes.
Remove from heat and let sit for 10 minutes before serving. Enjoy!
