What Kind of Potatoes Should I Use?

Ingredients for the Lyonnaise Potatoes

Each ingredient plays a key role in building flavor and texture in this timeless dish:

• Yukon Gold Potatoes – Their buttery flavor and firm texture make them ideal for slicing and pan-frying without falling apart.
• Yellow Onions – Slowly caramelized, they bring a deep, sweet flavor that enhances the richness of the potatoes.
• Unsalted Butter – For that golden brown finish and rich, indulgent taste.
• Olive Oil – Helps prevent the butter from burning and adds a slight fruity depth.
• Salt and Black Pepper – Essential seasonings to bring out the natural flavors.
• Fresh Parsley – A sprinkle of chopped parsley at the end adds color and a fresh finish.

How To Make the Lyonnaise Potatoes

Step 1: Parboil the Potatoes

Place sliced Yukon Gold potatoes in a pot of salted water. Bring to a boil and cook for 5–7 minutes until just tender but not falling apart. Drain and let them cool slightly.

Step 2: Caramelize the Onions

In a large skillet, melt 1 tablespoon of butter with 1 tablespoon of olive oil over medium-low heat. Add the sliced onions and cook slowly for about 15–20 minutes, stirring occasionally, until golden and sweet. Remove from skillet and set aside.

Step 3: Pan-Fry the Potatoes

In the same skillet, add the remaining butter and olive oil. Once hot, layer the potato slices in a single layer. Cook in batches if needed. Fry until golden and crispy on each side, about 3–4 minutes per side.

Step 4: Combine and Serve

Return the onions to the skillet, tossing them gently with the potatoes. Season with salt and pepper to taste. Sprinkle with chopped fresh parsley before serving.

How to Serve and Store Lyonnaise Potatoes

This savory side dish is best served hot, straight from the skillet. The crispy edges and buttery onions are at their peak when freshly cooked. Lyonnaise Potatoes are perfect for brunch, lunch, or dinner and comfortably feed 4 to 6 people as a side.

To store leftovers, let them cool completely before transferring to an airtight container. They can be refrigerated for up to 3 days. Reheat in a skillet over medium heat to bring back that crisp texture.

Frequently Asked Questions

Can I make Lyonnaise Potatoes ahead of time?

Yes, you can parboil the potatoes and caramelize the onions a day in advance. Store them separately in the fridge, then pan-fry and combine just before serving for the best texture.

What if I don’t have Yukon Gold potatoes?

You can use red potatoes or fingerlings as alternatives. Just avoid starchy varieties like Russets, which tend to break apart.

Can I use dried herbs instead of fresh parsley?

Yes, though fresh parsley offers a brighter flavor and better visual appeal. If using dried, use only a small pinch as it’s more concentrated.

Is it necessary to use both butter and olive oil?

Using both helps balance flavor and prevent the butter from burning. If you prefer one over the other, you can use just butter, but be sure to cook on medium-low heat.
