Prepare the scalloped potatoes and cream sauce

Slice the potato and red onion to uniform 1/8 inch slices using a mandolin.

Make the sauce. On the stove in a pan on medium heat, combine heavy cream, parsley, and paprika. Let the sauce simmer for 5 minutes while regularly stirring. Reduce heat to medium-low for an additional 5 minutes.

Arrange the campfire potatoes au gratin in a cast iron skillet

Grease the bottom of a medium sized cast iron skillet with some butter. In a bowl, season potatoes with garlic, salt, red chili flakes, and one tbsp of parsley.

Arrange potatoes and red onions in the cast iron skillet.

Alternate 2 inches of potatoes with 1-2 sections of red onions.

Once potatoes and onions are tightly packed, pour the cream sauce over the ingredients.

Do not overflow the cast iron skillet with the cream sauce.

Drizzle the melted butter over the potatoes and cover the cast iron skillet with foil. Add them to a grill or fire, not directly over heat.

How long does it take to cook potatoes au gratin on the grill or fire?

The potatoes will take about one hour to cook.

You may not have accurate temperature information when dealing with an open flame, so keep checking the potatoes at the 45 minute mark to see if they are done.

Once potatoes can be pierced with a fork, they are ready for the final step.

The cheese…

Cook, uncovered for 5 minutes or until cheese bubbles.

Take off the heat and sprinkle remaining parsley on top.

How to prepare potatoes au gratin for camping

Campfire potatoes au gratin will be one of the first dishes to start cooking since this recipe takes about one hour.

Wrap potatoes in heavy-duty foil or grill bags for an easy cleanup.

Cooking directly on a flame may cook the potatoes unevenly, so rotate the campfire potatoes occasionally. To be sure potatoes are done cooking, pierce them with a fork. If the fork easily pierces the potatoes, they are ready for the cheese.

Add gruyere cheese to the top of the campfire potatoes and finish on the grill until the cheese is melted and bubbling.

Adapting Campfire potatoes au gratin for the oven

To bake scalloped potatoes au gratin in the oven, follow the recipe prep instructions and cook the potatoes at 375 degrees in a casserole dish for about an hour. The potatoes are done when they are tender enough to pierce with a fork.

Once the potatoes are done, sprinkle with cheese and melt in the broiler on high until the cheese is bubbling.

Ingredients

Sauce

• 1 cup heavy cream
• 2 tsp paprika (or any spice you’d like)
• 2 medium russet potatoes peeled and sliced thin
• 1 tsp salt
• 4 cloves garlic diced
• 1 tsp red chili flakes (optional)
• 3 tbsp parsley chopped, divided
• 1 medium red onion sliced thin
• 3 tbsp unsalted butter melted
• 1/2 cup gruyere cheese shredded

Instructions

1. Slice the potato and red onion to uniform 1/8 inch slices using a mandolin.

2. Make the sauce. On the stove in a pan on medium heat, combine heavy cream, parsley, and paprika. Let the sauce simmer for 5 minutes while regularly stirring. Reduce heat to medium-low for an additional 5 minutes. 

3. Grease the bottom of a medium sized cast iron skillet with some butter. In a bowl, season potatoes with garlic, salt, red chili flakes, and one tbsp of parsley. Arrange potatoes and red onions in the cast iron skillet, alternating 2 inches of potatoes with 1-2 sections of red onions. Once potatoes and onions are tightly packed, pour the cream sauce over the ingredients. Do not overflow the cast iron skillet. The sauce will bubble up as it cooks. 
   

4. Drizzle the melted butter over the potatoes and cover the cast iron skillet with foil. Add them to a grill or fire, not directly over heat. The potatoes will take about one hour to cook. You may not have accurate temperature information, so keep checking the potatoes at the 45 minute mark to see if they are done. Once potatoes can be pierced with a fork, they are ready.
