Ingredients

Scale

Gather these ingredients to make Martha Stewart’s Slow Cooker Scalloped Potatoes:

  • 3 pounds Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 1 medium yellow onion, thinly sliced
  • 4 tablespoons unsalted butter, melted
  • 3 tablespoons all-purpose flour
  • 3 cups whole milk
  • 1 ½ cups shredded Gruyere cheese
  • 1 cup shredded cheddar cheese
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ¼ teaspoon ground nutmeg
  • 2 tablespoons chopped fresh parsley, for garnish (optional)

Instructions

Prepare the Sauce:

  1. Melt the Butter: In a large bowl, whisk together the melted butter and all-purpose flour until smooth. This will create a roux that will help thicken the sauce.

  2. Whisk in Milk: Gradually whisk in the whole milk, ensuring there are no lumps.

  3. Add Cheese and Seasoning: Stir in the shredded Gruyere and cheddar cheeses until melted and smooth. Season with salt, pepper, and ground nutmeg.

Layer the Potatoes:

  1. Grease the Slow Cooker: Lightly grease the inside of your slow cooker with butter or cooking spray.

  2. Create the First Layer: Arrange a layer of thinly sliced potatoes on the bottom of the slow cooker, overlapping slightly.

  3. Add Onion and Sauce: Sprinkle a layer of thinly sliced onion over the potatoes, then pour about one-third of the cheese sauce over the potatoes and onions.

  4. Repeat Layers: Repeat the layering process two more times: potatoes, onions, and sauce, until all ingredients are used. The top layer should be sauce.

Slow Cook the Potatoes:

  1. Cover and Cook: Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours, or until the potatoes are tender when pierced with a fork. Cooking times may vary depending on your slow cooker.

  2. Check for Doneness: After the cooking time is complete, check the potatoes to ensure they are fully cooked through. If not, continue cooking for an additional 30-60 minutes.

Serve:

  1. Let Rest: Let the scalloped potatoes rest in the slow cooker for 10-15 minutes before serving. This will allow the sauce to thicken slightly.

  2. Garnish: Garnish with chopped fresh parsley, if desired. Serve warm directly from the slow cooker.
