Ingredients

• 6 medium-sized potatoes, peeled and thinly sliced
• 1 packet French onion soup mix
• 2 cups sour cream
• 2 cups shredded cheddar cheese
• 1/2 cup butter, melted
• 1/4 cup milk
• Salt and pepper, to taste

Directions

1. Preheat the oven
   Preheat your oven to 350°F (175°C).
2. Prepare the baking dish
   Grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking.
3. Mix the sauce
   In a large mixing bowl, combine the sour cream, melted butter, milk, and the French onion soup mix. Stir until fully incorporated into a creamy mixture.
4. Layer the potatoes
   Arrange the thinly sliced potatoes evenly across the bottom of the greased baking dish.
5. Coat with sauce
   Pour the sour cream mixture over the potatoes, using a spoon or spatula to spread it evenly and coat all the slices.
6. Season
   Add salt and pepper to taste over the top.
7. Bake covered
   Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This step helps the potatoes cook through and absorb the creamy flavors.
8. Add cheese & finish baking
   After 45 minutes, remove the foil. Sprinkle the shredded cheddar cheese generously over the top. Return to the oven and bake uncovered for an additional 15 minutes, or until the cheese is melted, bubbly, and golden and the potatoes are fork-tender.
9. Serve hot
   Let the dish rest for a few minutes before serving. Serve hot and enjoy the creamy, cheesy deliciousness!

Pro Tips and Variations

• Slice evenly: Use a mandoline slicer to get consistent, thin potato slices for even baking.
• Add herbs: Top with chopped fresh thyme, rosemary, or parsley before baking for a herby twist.
• Extra crispy top: Broil for the last 2 minutes to give the cheese a golden, bubbly finish.
• Lighter version: Use light sour cream and reduced-fat cheddar if you want to cut back on richness.

Serving Suggestions

• Serve as a side dish with roast chicken, beef, or pork.
• Pairs beautifully with holiday mains like glazed ham or turkey.
• Great with a fresh green salad to balance the richness.
• Makes a satisfying vegetarian main when served with steamed veggies.

Storage/Reheating

• Refrigerator: Store leftovers in an airtight container in the fridge for up to 3–4 days.
• Reheat: Warm in the oven at 325°F until heated through to maintain the texture, or microwave in 30-second intervals.
• Freezing not recommended: The sour cream may separate after thawing.

FAQs

Can I prep this dish in advance?
Yes! Assemble the full dish (without baking) and store covered in the fridge for up to 24 hours before baking.

Can I use a different cheese?
Absolutely! Try mozzarella for a gooier finish or a mix of sharp cheddar and Gruyère for extra depth.

What if I don’t have sour cream?
You can substitute with plain Greek yogurt, though the flavor and texture will be slightly tangier.

Can I add meat?
Yes—cooked and crumbled bacon or ham makes a great addition to the potato layers.
