Step-by-Step Instructions for French Onion Potatoes

Step 1
Preheat your oven to 400°F (200°C). This is an essential first step as it allows the heat to evenly distribute and ensures your French Onion Potatoes cook perfectly. While the oven is warming up, gather your ingredients: condensed French onion soup, dry onion soup mix, melted butter, and diced potatoes. A properly preheated oven contributes to a beautifully golden crust on top of your casserole.

Step 2
Dice the potatoes into 1-inch cubes. Take your time with this step, ensuring that the pieces are roughly the same size for even cooking. If you choose to peel the potatoes for a smoother texture, that’s perfectly fine as well. Place the diced potatoes in a large bowl and set them aside while you prepare the sauce, allowing them to breathe a little before they meet their flavorful companions.

Step 3
In a 9x13 or oval casserole dish, combine the condensed French onion soup, dry onion soup mix, and melted butter. Stir the mixture well until everything is fully combined and the butter is evenly incorporated. This savory base is the heart of your French Onion Potatoes, providing those rich, comforting flavors. The texture of the mixture should be smooth, inviting you to mix in those delicious potatoes.

Step 4
Now, add the diced potatoes to the casserole dish and stir to coat them thoroughly in the onion mixture. Make sure every piece of potato is covered; this ensures that they soak up all that delightful flavor as they bake. The sight of glistening potatoes resting in that savory bath is sure to whet your appetite and set the stage for your delicious dish.

Step 5
Cover the casserole dish with aluminum foil, making sure it’s tightly sealed to hold in the moisture. Place the dish in the preheated oven and bake for about 30 minutes. During this time, the potatoes will soften a bit, absorbing the flavors of the French onion soup. The kitchen will start filling with a warm, inviting aroma that hints at the deliciousness to come.

Step 6
After the initial baking time, carefully remove the foil from the casserole dish. Continue baking the French Onion Potatoes for an additional 40 minutes, allowing the top to become nicely browned and the potatoes to reach a tender, melt-in-your-mouth texture. Keep an eye on them towards the end; you want them to look golden but not burnt.

Step 7
Once the potatoes are perfectly cooked, sprinkle a generous layer of shredded Gruyere cheese over the top. Return the dish to the oven and bake for an additional 10 minutes, or until the cheese is bubbling and has formed a golden crust. The melted cheese adds an indulgent element that makes these French Onion Potatoes truly irresistible.

Step 8
When the final baking time is up, carefully remove the casserole from the oven and let it cool for about 10 minutes. This brief resting time allows the flavors to settle and makes serving easier. For a pop of color and freshness, garnish your French Onion Potatoes with chopped parsley just before serving. Enjoy this comforting side dish, and watch as your family gathers around for seconds!
