Ingredients
Units
Scale
- 3 lbs russet or Yukon Gold potatoes, peeled and thinly sliced
- 1 large onion, thinly sliced
- 2 cups heavy cream
- 1 packet (1 oz) French onion soup mix
- 1 cup shredded Gruyère cheese (or Swiss cheese)
- 1/2 cup crispy fried onions (optional, for topping)
- 2 tbsp unsalted butter
- 1 tsp garlic powder
- 1/2 tsp salt
- 1/2 tsp black pepper
Instructions
- Prepare the Potatoes:
- Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
- Peel and slice the potatoes thinly using a mandoline or sharp knife.
- Make the Sauce:
- In a saucepan over medium heat, melt the butter. Add the onion slices and sauté until caramelized, about 10 minutes.
- Stir in heavy cream, French onion soup mix, garlic powder, salt, and pepper. Heat until the mixture begins to simmer. Remove from heat.
- Assemble the Bake:
- Layer half the sliced potatoes in the prepared baking dish. Pour half the cream mixture over the potatoes.
- Repeat with the remaining potatoes and cream mixture.
- Add Cheese and Bake:
- Cover the dish with foil and bake for 45 minutes. Remove foil, sprinkle with shredded Gruyère cheese, and bake for another 20-25 minutes until the cheese is golden and bubbly.
- Optional Topping:
- Sprinkle crispy fried onions on top during the last 5 minutes of baking for extra crunch.
- Serve:
- Let the bake rest for 10 minutes before serving to allow the sauce to thicken.
Notes
- Swap heavy cream with half-and-half for a lighter version.
- Gruyère cheese adds a nutty flavor, but cheddar or mozzarella works well too.
- For extra richness, add ¼ cup sour cream to the sauce
