Ingredients & Their Roles

• Unsalted butter (3 tablespoons, plus extra for greasing): Adds richness and helps create a silky base for the sauce while preventing sticking.
• Russet or Yukon Gold potatoes (2½ pounds): The heart of the dish. Russet potatoes create a creamy texture, while Yukon Gold hold their shape and offer a buttery flavor.
• Large yellow onions (2): Provide natural sweetness and depth, becoming beautifully soft and slightly caramelized during cooking.
• All-purpose flour (3 tablespoons): Thickens the sauce, creating that classic creamy consistency.
• Kosher salt (1 teaspoon): Enhances all the flavors and balances the sweetness of the onions.
• Black pepper (½ teaspoon, optional): Adds a gentle warmth and subtle spice.

Step-by-Step Instructions

1. Prepare the Slow Cooker:
   Lightly grease a 4- to 6-quart slow cooker with butter, focusing on the bottom and sides. This ensures easy removal and helps achieve golden, caramelized edges.
2. Slice the Potatoes:
   Peel the potatoes and slice them into thin rounds (about ⅛ inch thick). Use a mandoline or sharp knife for uniform slices, which ensures even cooking.
3. Prepare the Onions:
   Thinly slice the onions into rings or half-moons. These will soften and release their natural sweetness as they cook.
4. Build the Layers:
   Start with a layer of potatoes, followed by onions, then sprinkle a bit of flour, salt, and pepper. Add small dots of butter. Repeat the layers until all ingredients are used.
5. Cook to Perfection:
   Cover and cook on low for 6–7 hours or high for 3–4 hours, until the potatoes are fork-tender and the dish is bubbling.
6. Finish & Rest:
   Let the bake sit uncovered for 10–15 minutes before serving. This helps the sauce thicken and makes serving easier.
