How to Make French Onion Potatoes
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step ensures that your French Onion Potatoes will cook evenly.
Step 2: Prepare the Baking Dish
Grease a 9×13-inch baking dish with butter or cooking spray. This helps prevent sticking and makes for easy serving.
Step 3: Mix the Creamy Base
In a large mixing bowl, combine the sour cream, milk, melted butter, and French onion soup mix. Stir until well blended.
Step 4: Layer the Potatoes
Layer half of the sliced potatoes evenly in the prepared baking dish. Pour half of the creamy mixture over these potatoes. Repeat with remaining potatoes and cream mixture for a second layer.
Step 5: Bake Covered
Cover the baking dish with aluminum foil. Bake in the preheated oven for 45 minutes. This helps steam the potatoes until they are tender.
Step 6: Add Cheese Topping
Remove the foil carefully. Sprinkle shredded cheddar cheese on top of the potatoes. Bake uncovered for an additional 15 minutes or until the cheese is melted and bubbly.
Step 7: Serve Hot
Once done, remove from oven and let it cool slightly before serving. Enjoy this creamy, cheesy goodness as a perfect side or main dish!
