Ingredients
  

  • 3 pounds Yukon Gold potatoes sliced ⅛ inch thick
  • 3 tablespoons unsalted butter
  • 1 teaspoon unsalted butter for greasing
  • ½ cup finely diced yellow onion
  • 2 teaspoons minced garlic
  • 3 tablespoons all-purpose flour
  • 1½ cups whole milk
  • 1 cup heavy whipping cream
  • 2 cups shredded sharp cheddar cheese divided
  • ½ cup grated Parmesan cheese
  • 1 teaspoon Dijon mustard
  • 1 teaspoon kosher salt
  • ½ teaspoon ground black pepper
  • ½ teaspoon dried thyme
  • ¼ teaspoon paprika
  • 1 tablespoon chopped fresh chives optional

Instructions
 

  • Grease a 6-quart slow cooker with one teaspoon of butter.
  • Wash and thinly slice the potatoes into ⅛-inch rounds.
  • Melt three tablespoons of butter in a saucepan over medium heat. Add the onion and cook for three to four minutes.
  • Stir in the minced garlic and cook for 30 seconds.
  • Add the flour and stir for one minute.
  • Gradually whisk in the whole milk and heavy cream. Cook for three to five minutes over medium-low heat until slightly thickened.
  • Remove from the heat. Stir in 1½ cups of cheddar, Parmesan, Dijon mustard, salt, pepper, thyme, and paprika until smooth.
  • Spread a little sauce in the slow cooker. Add one-third of the potatoes, followed by one-third of the remaining sauce. Repeat twice.
  • Cover and cook on LOW for four to five hours or HIGH for 2½ to 3½ hours, until the potatoes are tender.
  • Sprinkle the remaining ½ cup of cheddar over the potatoes. Cover and cook for another 15 to 20 minutes until melted.
  • Turn off the slow cooker and let the potatoes rest for 15 minutes. Garnish with fresh chives and serve warm.

Notes

- Use freshly shredded cheese for a smoother sauce.
- Keep potato slices evenly sized for consistent cooking.
- Slow cooker temperatures vary, so check for tenderness rather than relying only on cooking time.
- Refrigerate leftovers in an airtight container for up to four days.
- Let the finished dish rest before serving to help the sauce thicken.
