If you're looking for a cozy, comfort food side dish that is simple to throw together and has outstanding flavor, these French Onion Potatoes will meet all the check marks.
With the fall/winter season at the tip of our nose, and oh yeah, the holidays are too, recipes like this are actually required in my opinion.
This dish is wonderful because you basically dump all the ingredients in a bowl, toss it together, and bake in a casserole dish; top with cheese at the end, and voila! You have a mouthwatering side dish your family will rave about.
I also love the rich onion flavors using a can of French onion soup, plus golden onion soup mix. The potatoes come out super creamy and infused with lots of savory goodness.

Simple Ingredients:
- Potatoes- I use peeled russet potatoes for this recipe.
- Onion soup mix- Golden onion soup mix offers a milder onion flavor.
- French onion soup- The soup helps cook the potatoes and infuse lots of savory onion flavors.
- Onion- I use a yellow onion and it offers fresh onion flavors.
- Cheese- Fontina cheese is super creamy and melts beautifully.
- Fresh herbs- Thyme, parsley, and chives.
- Seasonings- Ground black pepper.
Substitutions:
Potatoes- Other potatoes that work well for this recipe is Yukon gold and red potatoes.
Onion soup mix- You can also use the original Lipton onion soup mix in place of golden onion mix.
Onions- If you want to tone down the onion flavor simply omit the fresh onions.
Cheese- French onion potatoes is traditionally made with some type of swiss cheese. Use a Gruyere, provolone, mozzarella, or sharp cheddar cheese.
How To Make French Onion Potatoes:
See full instructions in recipe card below
Step One. Preheat oven to 375℉ and grease a baking dish with butter or cooking spray. In a large mixing bowl add soup, onion mix, melted butter, black pepper, thyme, potatoes and onions. Combine until potatoes are well coated.
Step Two. Pour potato mixture in a large baking dish and spread out in an even layer. Cover with foil and bake for 40-minutes. Remove the foil and stir potatoes. Place back in the oven uncovered for another 30-35 minutes. Top with cheese and bake another 5-minutes or until cheese is melted.
Step Three. When potatoes are tender and cheese is fully melted, remove the dish from the oven and top with fresh parsley and chivies. Allow to rest 5-10 minutes before serving.
Recipe Tip:
- Brown the top of the potatoes- If you want to brown the top layer, place the potato dish under the broiler after the baking time is complete. This should only take about 30-seconds so keep an eye on it so the top doesn't burn. It will offer some golden bits on top.
Common Questions:
Yes! Assemble the potato dish, uncooked, up to one day in advance. When ready to bake, remove from the refrigerator 1-hour before the baking time then follow the instructions for baking in the recipe card.
There should be some liquid in the bottom of the pan after the final baking time. Allowing it to rest for 5-10 minutes, and this will give the potatoes a chance to absorb most of the liquid.
This recipe will keep fresh in the refrigerator for up to 5 days. Reheat in the microwave or add potatoes to an oven safe dish covered with foil. Warm the potatoes at 350℉ for 20-30 minutes or until heated through.
