How to Make French Onion Potatoes
Step 1: Preheat the Oven
Preheat oven to 350°F (175°C). This temperature is ideal for baking the potatoes until they are tender yet not overcooked.
Step 2: Prepare Your Baking Dish
Grease a 9×13-inch baking dish with butter or cooking spray. This prevents sticking and ensures easy serving later on.
Step 3: Make the Creamy Mixture
In a large mixing bowl:
1. Combine sour cream, milk, melted butter, and French onion soup mix.
2. Stir until well blended. Set aside for layering.
Step 4: Layer the Potatoes
Place the thinly sliced potatoes in your prepared baking dish:
– Start by laying half of the potato slices evenly across the bottom.
– Pour half of the creamy mixture over this layer. Repeat with remaining potatoes and mixture.
Step 5: Bake Covered
Cover the baking dish tightly with aluminum foil:
– Bake in preheated oven for 45 minutes. This will allow the potatoes to steam and become tender.
Step 6: Add Cheese Topping
After 45 minutes:
– Remove the foil carefully.
– Sprinkle shredded cheddar cheese evenly over the top of the potatoes.
Step 7: Bake Uncovered
Return to the oven:
– Bake uncovered for an additional 15 minutes, or until cheese is bubbly and golden brown, and potatoes are fully cooked through.
Step 8: Serve Hot
Once done, take out of the oven. Let cool slightly before serving hot. Enjoy your creamy, cheesy French Onion Potatoes!

How to Perfect French Onion Potatoes
To ensure your French Onion Potatoes turn out perfectly, follow these simple tips.
- Choose the right potatoes: Use starchy potatoes like Russets for optimal creaminess.
- Layer evenly: Spread the potatoes in an even layer to ensure even cooking and easy serving.
- Mix thoroughly: Combine the sour cream mixture well so every potato slice is coated with flavor.
- Bake covered initially: Covering helps steam the potatoes, making them tender before browning.
- Use fresh cheese: Freshly shredded cheddar melts better than pre-packaged options, enhancing texture.
- Let it rest: Allow the dish to sit for a few minutes after baking; it will firm up and be easier to serve.
Best Side Dishes for French Onion Potatoes
French Onion Potatoes make an excellent centerpiece, but pairing them with complementary side dishes enhances the meal experience. Here are some ideas:
- Grilled Vegetables: A colorful mix of bell peppers, zucchini, and asparagus adds freshness and crunch.
- Caesar Salad: Crisp romaine lettuce tossed in Caesar dressing provides a refreshing contrast.
- Roasted Brussels Sprouts: These add a slight bitterness that balances the creaminess of the potatoes.
- Garlic Bread: Perfect for soaking up any leftover sauce while adding buttery goodness to your plate.
- Corn on the Cob: Sweet corn pairs well and adds vibrant color; consider grilling it for extra flavor.
- Coleslaw: A tangy slaw introduces acidity, cutting through the richness of the French Onion Potatoes.
Common Mistakes to Avoid
When making French Onion Potatoes, it’s easy to overlook some key steps. Here are common mistakes to avoid for a perfect dish.
- Skipping the slicing technique: Not slicing the potatoes evenly can lead to uneven cooking. Use a mandoline or sharp knife to achieve consistent thickness.
- Ignoring seasoning: Under-seasoning can make your dish bland. Be sure to taste and adjust the salt and pepper as needed before baking.
- Not covering while baking: Failing to cover the dish with foil initially can dry out the potatoes. Covering helps retain moisture and ensures even cooking.
- Overloading with cheese: While cheese is delicious, too much can overpower the dish. Stick to the recommended amount for a balanced flavor.
- Rushing the cooking time: Cooking for too short a time may leave the potatoes hard. Follow the recipe’s baking times closely for tender results.
