Servings

Serves: 6–8 people
Preparation Time: 20 minutes
Cooking Time: 5–6 hours (low) or 3–4 hours (high)

Ingredients

Potatoes

• 3 pounds (about 6–8 medium) Yukon Gold or Russet potatoes, thinly sliced
• 1 medium onion, thinly sliced
• 3 cloves garlic, minced

Creamy Sauce

• 2 cups heavy cream or half-and-half
• 1 cup milk
• 3 tablespoons butter
• 3 tablespoons all-purpose flour
• 1 teaspoon salt (adjust to taste)
• ½ teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ teaspoon paprika
• 1 teaspoon dried thyme (optional)

Cheese Layer

• 1½ cups shredded cheddar cheese
• ½ cup mozzarella or Parmesan cheese
• Fresh parsley for garnish (optional)

Instructions

1. Prepare the Potatoes

• Wash and peel potatoes if desired.
• Slice potatoes evenly into thin rounds (about ⅛ inch thick).
• Keep slices similar in size so they cook evenly.

2. Make the Cream Sauce

• Melt butter in a saucepan over medium heat.
• Add flour and whisk for 1 minute.
• Slowly add milk and cream while whisking.
• Cook until slightly thickened.
• Add salt, pepper, garlic powder, onion powder, paprika, and thyme.

3. Layer in Slow Cooker

• Grease the slow cooker with butter or cooking spray.
• Add a layer of potatoes.
• Add some onion, garlic, sauce, and cheese.
• Repeat layers until ingredients are used.
• Finish with remaining sauce and cheese.

4. Slow Cook

• Cover and cook:
  • LOW: 5–6 hours
  • HIGH: 3–4 hours
• Potatoes are ready when a fork easily slides through them.

5. Finish and Serve

• Let rest for 10 minutes before serving.
• Garnish with parsley or extra cheese.

Recipe Notes

• Slice potatoes evenly: Uneven slices may cause some potatoes to remain firm while others become too soft.
• Best potatoes: Yukon Gold gives a creamy texture, while Russet potatoes create a softer, more traditional scalloped potato texture.
• Avoid watery potatoes: Do not rinse sliced potatoes after cutting because the starch helps thicken the sauce.
• Cheese choice: Sharp cheddar gives the best flavor, but you can mix cheeses.
• Make ahead: Assemble the dish a few hours before cooking and refrigerate until ready.

Helpful Tips

✅ Use a mandoline slicer for quick, even potato slices.
✅ Add cooked bacon or ham for a complete meal.
✅ For extra richness, add cream cheese to the sauce.
✅ If the sauce looks thin, cook uncovered for 15–20 minutes at the end.
✅ Letting the dish rest helps the sauce thicken.
