Ingredients

3 pounds Yukon Gold potatoes, peeled and thinly sliced (about ⅛-inch thick)
1 medium onion, thinly sliced (optional)
2 cups shredded sharp cheddar cheese
1 (10.5-ounce) can condensed cream of mushroom soup (or cream of chicken)
1 cup whole milk (or half-and-half for extra richness)
3 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika (optional, for color)
2 tablespoons unsalted butter, cut into small pieces (for the top)

Directions

1. Prepare the slow cooker. Lightly grease the inside of your slow cooker with butter or cooking spray.

2. Make the sauce. In a medium bowl, whisk together the cream of mushroom soup, milk, minced garlic, salt, pepper, and paprika until smooth.

3. Layer the potatoes. Arrange a layer of the thinly sliced Yukon Gold potatoes in the bottom of the slow cooker, slightly overlapping them. Top with some of the sliced onions (if using) and a sprinkle of shredded cheese. Repeat the layers, ending with a layer of cheese on top.

4. Pour the sauce. Pour the sauce mixture evenly over the layered potatoes and cheese. Gently press down with the back of a spoon to help the sauce settle between the layers. Dot the top with the small pieces of butter.

5. Cook. Cover the slow cooker with the lid and cook on LOW for 4 to 6 hours, or on HIGH for 2½ to 3 hours, until the potatoes are very tender when pierced with a fork and the sauce is bubbling and thick.

6. Rest and serve. Turn off the slow cooker and let the dish rest, covered, for 10-15 minutes. This allows the sauce to thicken slightly and makes it easier to serve. Garnish with fresh parsley if desired and serve warm.

Variations

Different cheese: Try Gruyère, Monterey Jack, or a blend of cheeses.
Add ham: Layer in 2 cups of diced cooked ham for a complete meal.
Herb-infused: Add fresh thyme or rosemary to the sauce.
Garlic lovers: Increase garlic to 4-5 cloves or add roasted garlic.
Spicy kick: Add a pinch of cayenne or red pepper flakes.
Creamier: Use half-and-half or heavy cream instead of milk.
Vegetarian: Use cream of celery or cream of mushroom soup.

Expert Tips

Use a mandoline. For perfectly even slices, use a mandoline slicer set to ⅛-inch thickness.
Don’t layer too thick. Keep potato slices thin and layers even for consistent cooking.
Don’t lift the lid. Try not to peek during the first 2-3 hours—the steam needs to stay inside.
Let it rest. Allowing the dish to rest helps the sauce thicken.
Yukon Golds are best. Their buttery texture and thin skins make them ideal for scalloped potatoes.

Storage and Reheating

Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheating: Reheat in the microwave or in a 350°F oven for 15-20 minutes. Add a splash of milk if the sauce seems thick.

Freezing: This dish freezes well for up to 3 months. Thaw overnight before reheating.
