Ingredients
- 1 (10-oz) can French onion soup
- 1 (1-oz) envelope dry onion soup mix
- ½ cup (1 stick) butter, melted
- 2.5 lbs russet potatoes, peeled and cut into 1-inch pieces
- 2 cups shredded Gruyère cheese
Instructions
1️⃣ Preheat the Oven:
Preheat your oven to 375°F (190°C).
2️⃣ Mix the Soups & Butter:
In a large bowl, combine French onion soup, dry onion soup mix, and melted butter. Stir well to combine.
3️⃣ Prepare the Potatoes:
Peel the russet potatoes and cut them into 1-inch cubes. Add them to the soup mixture and toss until evenly coated.
4️⃣ Assemble the Casserole:
Pour the potato mixture into a 13×9-inch baking dish, spreading evenly.
5️⃣ Bake Covered:
Cover the dish tightly with aluminum foil and bake for 30 minutes.
6️⃣ Uncover & Continue Baking:
Remove the foil and bake for another 30-45 minutes, stirring 2-3 times to ensure even cooking, until the potatoes are tender and golden brown.
7️⃣ Add Cheese & Melt:
Sprinkle the shredded Gruyère cheese over the hot potatoes. Cover the dish again with foil and let it rest for 5-10 minutes to allow the cheese to melt and the flavors to meld.
8️⃣ Serve & Enjoy:
Garnish with fresh parsley (optional) and serve warm!
Notes
- Cheese Substitutions: If you don’t have Gruyère, try Swiss, mozzarella, or white cheddar for a similar creamy melt.
- Extra Crispy Potatoes? Broil for 2-3 minutes after adding the cheese for a golden, bubbly finish.
- Make Ahead: Assemble the dish up to 24 hours in advance, cover, and refrigerate. Bake as directed when ready to serve.
- Storage & Reheating: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for 15 minutes.
