There’s something deeply comforting about the sound of potatoes sizzling in a pan, especially when onions slowly soften and turn golden right beside them. Lyonnaise Potatoes have a way of transporting me straight back to simple, unfussy meals where the food didn’t need to be complicated to feel special. This dish reminds me of evenings when dinner was built around what we had on hand, when patience mattered more than perfection, and when the aroma alone was enough to bring everyone into the kitchen.

The first time I made Lyonnaise Potatoes at home, I was looking for a quick side dish for dinner that felt a little more elevated than plain roasted potatoes. I wanted something cozy, rustic, and deeply flavorful — the kind of food that pairs just as well with a fancy holiday roast as it does with a simple weekday meal. That’s exactly what this recipe delivers.

There’s magic in the way thinly sliced potatoes crisp in butter, soaking up the sweetness of caramelized onions while staying tender inside. It’s humble food, rooted in French home cooking, yet it never feels boring. Whether you’re serving this for holidays, family dinners, or a casual brunch spread, Lyonnaise Potatoes have a timeless charm that always feels right.

If you’ve ever loved an oven roasted potato recipe or a classic cheesy potato side dish, this version will feel familiar — but lighter, simpler, and incredibly satisfying.

Ingredient Notes & Details

Potatoes
Yukon Gold potatoes are ideal for Lyonnaise Potatoes. They hold their shape while becoming beautifully tender. Russet potatoes work too but will be slightly crispier and less creamy.

Onions
Yellow onions are traditional and offer the best balance of sweetness and depth when caramelized slowly.

Butter
Butter gives these potatoes their signature richness. For extra depth, you can use a mix of butter and olive oil.

Olive Oil
Helps prevent the butter from burning and adds a subtle savory note.

Garlic
Optional, but highly recommended for added aroma and flavor.

Fresh Parsley
Adds brightness and color, balancing the richness of the potatoes.

Salt and Black Pepper
Essential for drawing out moisture and enhancing natural flavors.

Thyme or Herbs de Provence
Optional, but adds a classic French touch that complements the onions perfectly.

Step-by-Step Instructions

Prepare the potatoes
Peel the potatoes if desired, then slice them into thin, even rounds about ⅛-inch thick. Uniform slices ensure even cooking and perfect texture.

Parboil for tenderness
Bring a large pot of salted water to a boil. Add the potatoes and cook for 5–7 minutes, just until slightly tender but not fully cooked. Drain well and let them steam dry.

Cook the onions slowly
Heat butter and olive oil in a large skillet over medium heat. Add the sliced onions with a pinch of salt. Cook slowly, stirring occasionally, until soft, golden, and lightly caramelized — about 12–15 minutes.

Add the potatoes to the skillet
Increase heat slightly and gently add the drained potatoes to the onions. Spread them into an even layer.

Let them crisp undisturbed
Allow the potatoes to cook without stirring for 4–5 minutes so they develop a golden crust on the bottom.

Flip and season
Carefully turn the potatoes using a spatula. Season with salt, pepper, garlic, and herbs. Cook another 4–5 minutes until golden and tender.

Finish with herbs
Remove from heat and sprinkle with fresh parsley just before serving.
