1. Preheat and Prepare the Ingredients

• Preheat oven to 400°F (200°C).
• Thinly slice the potatoes using a mandolin or a sharp knife to create uniform slices for even cooking.

2. Make the Cream Sauce

• Melt butter in a saucepan over medium heat.
• Add chopped garlic and sauté for 1–2 minutes until fragrant.
• Pour in heavy cream, then stir in salt and cumin.
• Add the sliced potatoes and bring the mixture to a gentle simmer.
• Cook for 5–7 minutes, stirring occasionally, until the cream thickens and the potatoes start to soften.

3. Assemble the Dish

• Grease a 6-inch oven-safe skillet or baking dish with butter.
• Use a fork or tongs to layer half of the potatoes in a flat or spiral arrangement.
• Spread half of the salsa, half of the cheese, and half of the scallions on top.
• Repeat the layering process with the remaining potatoes, salsa, cheese, and scallions.

4. Bake the Scalloped Potatoes

• Place the dish in the preheated oven and bake for 40 minutes, or until:
  • The top is bubbling and golden brown.
  • The potatoes are fully tender when pierced with a fork.

5. Garnish and Serve

• Sprinkle with chopped fresh cilantro before serving.
• Serve hot and enjoy!
