Ingredient Breakdown
To create the perfect Lyonnaise Potatoes, you’ll need just a handful of quality ingredients. Here’s what you’ll need:
- 3 pounds russet potatoes: These starchy potatoes are ideal for achieving that fluffy inside and crispy exterior.
- 1 large onion (thinly sliced): Sweet and mild, onions add depth and flavor as they caramelize.
- 4 tablespoons unsalted butter (divided): Butter enriches the potatoes and aids in achieving a golden crust.
- 2 tablespoons extra virgin olive oil: This adds a touch of richness and helps prevent the butter from burning.
- 2 tablespoons fresh parsley (chopped): A sprinkle of fresh parsley adds brightness and color to the dish.
- Salt and pepper (to taste): Essential for enhancing the flavors of the dish.
Essential Tools for Success
Before we get cooking, having the right tools can make all the difference. Here’s what you will need:
- Sharp knife: For slicing the potatoes and onions efficiently.
- Cutting board: A sturdy surface to prep your ingredients.
- Large skillet: A heavy-bottomed skillet ensures even cooking and browning.
- Spatula: To help flip and turn the potatoes without breaking them.
- Potato peeler: For quick and easy peeling of your russet potatoes.
Lyonnaise Potatoes: How It’s Done

Now that you have all your ingredients and tools ready, let’s get started on making Lyonnaise Potatoes!
Step 1: Prep the Potatoes
Start by peeling the russet potatoes. Once peeled, slice them into uniform ¼-inch thick rounds. This ensures even cooking.
Step 2: Soak the Potatoes
To remove excess starch and prevent the potatoes from turning brown, soak them in a bowl of cold water for about 30 minutes. After soaking, drain and pat them dry with a clean kitchen towel.
Step 3: Cook the Onions
In a large skillet, melt 2 tablespoons of unsalted butter and 2 tablespoons of extra virgin olive oil over medium heat. Add the thinly sliced onions and a pinch of salt. Cook for about 10-15 minutes, stirring occasionally, until they are caramelized and golden brown. Remove the onions from the skillet and set aside.
Step 4: Brown the Potatoes
In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the sliced potatoes, spreading them out in an even layer. Season with salt and pepper. Allow them to cook without stirring for about 5-7 minutes until they start to brown on one side.
Step 5: Flip the Potatoes
Using a spatula, carefully flip the potatoes to allow the other side to brown. Add the caramelized onions back into the skillet and gently mix everything together. Cook for another 10-15 minutes, stirring occasionally, until the potatoes are tender and golden brown.
Step 6: Finish and Garnish
Once the potatoes are cooked through, remove them from heat. Sprinkle the chopped fresh parsley over the top for a burst of freshness and color. Serve your Lyonnaise Potatoes warm and enjoy the deliciousness!
Seasonal Twists

While the classic Lyonnaise Potatoes are always a hit, consider trying these seasonal twists to keep things interesting:
- Spring: Add peas or asparagus for a pop of color and flavor.
- Summer: Toss in some cherry tomatoes or zucchini for a fresh summer vibe.
- Fall: Incorporate roasted garlic or a sprinkle of nutmeg for a cozy autumn taste.
- Winter: Add sautéed kale or spinach for a heartier dish.
Errors to Dodge
Even simple recipes can have their pitfalls. Here are some common mistakes to avoid when making Lyonnaise Potatoes:
- Skipping the soaking: Not soaking the potatoes can lead to a gummy texture. Always soak to get that crispy finish.
- Overcrowding the skillet: Too many potatoes in the pan can lead to steaming rather than browning. Cook in batches if necessary.
- Not using enough fat: Butter and oil are essential for achieving that perfect crisp. Don’t skimp on them!
- Stirring too frequently: Letting the potatoes sit undisturbed allows them to develop a nice crust. Avoid constant stirring.
Storage Pro Tips
If you have leftovers (though it’s unlikely!), here are some tips for storing your Lyonnaise Potatoes:
- Refrigeration: Place leftover potatoes in an airtight container and store in the fridge for up to 3 days.
- Reheating: For the best texture, reheat in a skillet over medium heat to regain that crispy exterior.
- Freezing: It’s not recommended to freeze Lyonnaise Potatoes, as the texture will suffer upon thawing.
Troubleshooting Q&A
What if my potatoes are mushy?
Mushy potatoes often result from overcooking or not soaking them prior to cooking. Ensure you soak the potatoes for at least 30 minutes and monitor the cooking time closely.
Can I use other types of potatoes?
While russet potatoes are preferred for their texture, Yukon Gold or red potatoes can also work well. Just keep in mind that the texture may differ slightly.
Why are my potatoes not browning?
If your potatoes aren’t browning, check if the skillet is overcrowded or if the heat is too low. Make sure to cook them in a single layer and adjust the heat as necessary.
Is it okay to prepare the onions ahead of time?
Yes! You can caramelize the onions a day in advance and store them in the fridge. Just reheat them before adding them to the potatoes.
