Lyonnaise Potatoes are crispy on the outside and creamy within. Tossed with soft, buttery onions and finished with parsley, it’s a classic French side dish that everyone loves.

Parboiling the potato slices before pan frying both speeds preparation and enhances crispiness by removing excess starch. And frying in a mixture of oil and butter prevents the butter from over browning as often happens with butter alone.

Serve With: 7 Menu Suggestions

Lyonnaise Potatoes make a wonderful companion to most main courses and side dishes (as do Fondant Potatoes and Gratin Dauphinois- two other classic French potato sides), but here are a few that pair particularly well:

  1. Chicken Ballotine and Arugula Salad
  2. Chicken Kabobs in the Oven and Spinach Strawberry Walnut Salad
  3. Easy Duck Leg Confit (made in the slow cooker), Garlic Butter Mushrooms and Roasted Broccoli and Cauliflower
  4. Coq au Vin Blanc and a mixed green salad dressed with Champagne Vinaigrette
  5. Roasted Boneless Leg of Lamb and Strawberry Spinach Salad for your Easter table.
  6. Savory Crepes and Baked Eggs (for a stellar brunch!)
  7. Salad Lyonnaise (Also hailing from the French city of Lyon, these two are a perfect pair!)

How to Make Lyonnaise Potatoes

Step 1: Cook onions in a large, non-stick skillet until caramelized in a mixture of butter and oil. Remove from skillet and set aside.

Step 2: While the onion cooks, parboil the potato slices in water. Drain and set aside.

Step 3: To same non-stick skillet, cook partially cooked potato slices in a mixture of butter and oil, turning a few times until crisp on both sides. Gently stir in reserved onions and season to taste with salt and pepper. Transfer to platter and garnish with fresh parsley; serve.

The simple and classic pan-fried potato and onion dish from the French city of Lyon.

Ingredients  

  • 2 tablespoons avocado oil or other high heat oil, divided
  • 2 tablespoons butter ideally high fat, European style butter, divided
  • 2 medium yellow onions or sweet onions, halved top to bottom and thinly sliced
  • kosher salt to taste
  • 1 1/2 pounds Yukon Gold potatoes or peeled russet potatoes, (see recipe note)
  • freshly ground black pepper
  • 1/4 cup finely chopped fresh parsley

Instructions 

  • Heat one tablespoon each of avocado oil and butter in a large, non-stick skillet over medium heat until sizzling. Add onions and a generous pinch of salt; cook, stirring often until soft and lightly golden, 15-20 minutes. Remove from heat and transfer to a bowl (set skillet aside for potatoes – no need to wipe it out).
  • Meanwhile, slice potatoes crosswise 1/4-inch thick and place in medium saucepan (if you have a mandoline slicer, this is a great time to use it). Add enough cold water to cover along with a generous pinch of salt; bring to boil over medium-high heat. Boil until nearly tender, about 3 minutes, skimming foam as needed. Drain and set aside.
  • Place the same large, non-stick skillet over medium heat and add remaining avocado oil and butter and heat until sizzling. Add parboiled potato slices and cook 15-18 minutes, gently flipping every 3 minutes to crisp potato slices on both sides. Once potatoes are crisp to your liking and cooked through, return onions to skillet and season to taste with salt and pepper; cook and stir until heated through, about 2 minutes. Transfer to platter and sprinkle with fresh parsley; serve hot.

Notes

  1. Starchy baking potatoes are the traditional potato used in this dish, but I prefer Yukon Gold potatoes for their blend of waxy / starchy texture. They don’t need to be peeled, crisp up nicely, and hold their shape better than russets. But either work well.
