By Editor • September 11, 2026 • 1 min read
Potatoes take center stage in the kitchen with this easy five-ingredient French onion potato bake. Perfect for any occasion, this dish captures the essence of French onion soup, making it a must-try side for your next meal.
Ingredients You’ll Need
To whip up this creamy casserole, you'll need russet potatoes, which should be large and similar in size for uniform cooking. If you prefer, Yukon Golds can be used, but they may require a bit of additional flour to thicken the sauce. The other three essential ingredients include sour cream, heavy cream, and either Gruyère or Swiss cheese, along with a packet of French onion soup mix.
Preparation Made Easy
This recipe is all about convenience. You can prepare the dish the day before and bake it when you're ready. Soak sliced potatoes in ice water to prevent browning, then mix your creamy sauce and layer it all together. After baking covered for about an hour, simply sprinkle cheese on top and bake for an additional ten minutes. For those cooking for fewer people, halving the recipe works perfectly in a smaller dish.
Tips for Perfect Potatoes
Using a mandoline is recommended for slicing the potatoes evenly, ensuring they cook thoroughly. If you don’t have one, a sharp chef's knife will do, but take care to slice in a single motion for the best results. For those looking to skip the soup packet, a homemade seasoning mix or caramelized onions can create a rich flavor profile that rivals the original.
