Ingredients

• 4 medium potatoes, thinly sliced

• 1 cup sour cream

• 1 cup shredded cheddar cheese

• 1 packet (1 oz) dry onion soup mix

Optional add-ins: 1/2 cup milk, 1 teaspoon garlic powder, a pinch of black pepper, and fresh chives for serving.

Directions

1. Preheat oven to 350°F and lightly grease a 9×13-inch baking dish.

2. In a medium bowl, stir together the sour cream, 3/4 cup of the shredded cheddar, dry onion soup mix, and milk if using (and garlic powder and pepper, if using) until smooth.

3. Arrange the sliced potatoes in an even layer in the prepared baking dish, then spread the sour cream mixture evenly over the top. Sprinkle the remaining cheddar over everything.

4. Cover with foil and bake for 45 minutes. Remove the foil and bake 15 to 20 minutes more, until the potatoes are tender and the top is golden and bubbly.

5. Let stand 5 minutes, garnish with fresh chives, and serve warm.

Serving Ideas

This dish is lovely served alongside roasted chicken, glazed ham, or a holiday turkey dinner. For a cozy plate, pair it with crusty bread and a crisp green salad, or serve it as a light vegetarian main with steamed greens.

Variations & Tips

• Potato Tip: Slice the potatoes thinly and evenly—about 1/8 inch thick—so they cook at the same rate.

• Sour Cream Tip: Full-fat sour cream gives the creamiest result and holds up best in the oven.

• Add-Ins: A handful of cooked crumbled bacon or sliced mushrooms layered between the potatoes adds extra flavor and texture.

• Storage: Cover leftovers tightly and refrigerate up to 4 days; reheat in the oven with a splash of milk so the potatoes stay creamy.
