Ingredients & Their Roles

• 3 tablespoons salted butter, melted (plus extra for greasing) – Adds richness and prevents sticking while enhancing overall flavor.
• 2 pounds russet or Yukon Gold potatoes (thinly sliced) – The heart of the dish, providing a creamy texture when slow-cooked.
• 2 large yellow onions (thinly sliced) – Bring natural sweetness and depth as they soften and lightly caramelize.
• 1 teaspoon salt – Enhances flavor and balances the natural sweetness of the onions.
• ½ teaspoon black pepper – Adds a gentle kick and warmth.
• 1 teaspoon garlic powder (optional) – Infuses subtle savory depth.
• ½ teaspoon dried thyme or parsley (optional) – Adds a fresh, aromatic touch.

Step-by-Step Instructions

1. Prepare the Slow Cooker:
   Lightly grease the inside of a 4- to 6-quart slow cooker with butter to prevent sticking and add extra flavor.
2. Slice the Ingredients:
   Thinly slice the potatoes (about ⅛-inch thick) and onions (⅛–¼ inch thick) for even cooking.
3. Layer the Base:
   Place a layer of potatoes on the bottom of the slow cooker, followed by a layer of onions. Sprinkle lightly with salt, pepper, and optional seasonings.
4. Repeat the Layers:
   Continue layering potatoes and onions, seasoning each layer as you go, until all ingredients are used.
5. Add Butter:
   Drizzle the melted butter evenly over the top, allowing it to seep down through the layers.
6. Cook Low and Slow:
   Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are fork-tender.
7. Optional Crisp Finish:
   For a slightly crispy top, transfer to an oven-safe dish and broil for 3–5 minutes after cooking.
