How to Make French Onion Potato Bake
Step 1: Prepare the Onions
Begin by heating the large skillet over medium heat. Add the butter and olive oil. Once melted, add the sliced onions along with salt, pepper, sugar (if using), garlic powder, and thyme. Cook for about 20-25 minutes until they are golden brown and caramelized. Stir occasionally to prevent burning.
Step 2: Preheat the Oven
While the onions are cooking, preheat your oven to 375°F (190°C). Grease your baking dish with butter generously.
Step 3: Layer the Potatoes
Arrange half of the sliced potatoes in an even layer at the bottom of your baking dish. Sprinkle with salt, pepper, and some fresh thyme leaves.
Step 4: Add Caramelized Onions
Spread half of the caramelized onion mixture over the potatoes evenly. Then sprinkle half of each cheese type over the onions.
Step 5: Repeat Layers
Repeat layering with the remaining potatoes, followed by another layer of caramelized onions and cheeses.
Step 6: Pour Cream Mixture
In a bowl, combine heavy cream (or milk) with salt, pepper, and fresh thyme leaves. Pour this mixture evenly over all layers in the baking dish.
Step 7: Bake
Cover your baking dish with foil to prevent excessive browning. Bake in the preheated oven for about 45 minutes. After that time has passed, remove the foil and bake for an additional 15-20 minutes until bubbly and golden on top.
Step 8: Serve
Once done baking, let it cool slightly before garnishing with fresh thyme sprigs and crispy fried onions if desired. Serve warm as a delicious side or main course! Enjoy your French Onion Potato Bake!

How to Perfect French Onion Potato Bake
Perfecting your French Onion Potato Bake elevates this dish from simple to spectacular. Here are some tips to make it shine.

- Caramelize Onions Well: Take your time while caramelizing onions; this brings out their natural sweetness and depth of flavor.
- Layer Carefully: Alternate layers of potatoes and onions evenly for uniform cooking and taste.
- Grate Cheese Yourself: Freshly grated cheese melts better than pre-packaged options, giving you a creamier texture.
- Let it Rest: Allowing your bake to rest for about 10 minutes after baking helps it set and makes serving easier.
Best Side Dishes for French Onion Potato Bake
Pairing side dishes with your French Onion Potato Bake can enhance your meal. Here are some great options that complement its flavors beautifully.

Common Mistakes to Avoid
To ensure your French Onion Potato Bake turns out perfectly, avoid these common mistakes.
- Skipping the caramelization: Caramelizing the onions enhances their flavor. Take your time and cook them slowly until golden brown for the best taste.
- Using the wrong potatoes: Not all potatoes are created equal. Stick to Yukon Gold or similar waxy potatoes to maintain a creamy texture.
- Overcrowding the dish: Layering too many potatoes can lead to uneven cooking. Make sure to arrange them in a single layer for optimal baking.
- Ignoring seasoning adjustments: Taste is key! Don’t forget to adjust salt and pepper according to your preference before baking.
- Not greasing the pan properly: A well-greased dish prevents sticking and makes serving easier. Use butter or oil generously on all sides of the baking dish.
