how to make French Onion Potatoes
Ingredients
- 1 10-oz can French onion soup
- 1 1-oz envelope dry onion soup mix
- 1/2 cup (1 stick) butter, melted
- 2.5 lbs russet potatoes
- 2 cups shredded gruyere cheese
Directions
- Preheat the oven to 375 degrees.
- In a large bowl, combine the condensed soup, dry soup mix, and melted butter. Stir well to mix everything together.
- Peel the potatoes and cut them into 1-inch pieces. Add these pieces to the soup mixture and stir to ensure they are well coated.
- Pour the mixture into a 13×9 inch baking dish, spreading the potatoes evenly in the dish.
- Cover the dish tightly with aluminum foil and bake at 375 degrees for 30 minutes.
- After 30 minutes, remove the foil and continue baking for another 30-45 minutes, or until the potatoes are tender. Stir 2-3 times during this baking time to help them cook evenly.
- Once the potatoes are tender, top them with the shredded cheese. Cover the dish tightly with foil again and let it rest for about 5-10 minutes. This will help the potatoes soak up the soup and allow the cheese to melt perfectly.
