Potatoes Lyonnaise

Prep Time: 25 minutes
Cook Time: 60 minutes

This is a takeoff on the classic French dish of browned potato slices, caramelized onion slices, butter and parsley. Here, the butter is mixed with olive oil for a slightly lighter result. Serve these potatoes with nearly any dish.  


  • 8 to 10 medium Yukon Gold or white potatoes, about 2 1/2 lb. total  
  • 2 Tbs. salt 
  • 5 Tbs. unsalted butter  
  • 5 Tbs. olive oil 
  • 1 lb. yellow onions, thinly sliced  


Place the potatoes in a large pot and add water to cover by 3 inches. Add 1 Tbs. of the salt and bring to a boil over high heat. Cover, reduce the heat to medium-low and cook until the potatoes are tender when pierced with a fork, 30 to 35 minutes.

Drain the potatoes, place under cold running water until cool and drain again. Let cool completely. Cut the potatoes into slices 1/2 inch thick. Refrigerate until ready to do the second cooking.

In a large fry pan over medium-high heat, melt 2 Tbs. of the butter with 3 Tbs. of the olive oil. Add the sliced potatoes in a single layer, sprinkle with 1 1/2 tsp. of the salt and cook until golden, 7 to 8 minutes. Turn the potatoes over, sprinkle with the remaining 1 1/2 tsp. salt and cook until golden on the other side, about 5 minutes. Transfer to paper towels to drain.

In another fry pan over medium-high heat, melt the remaining 3 Tbs. butter with the remaining 2 Tbs. olive oil. Add the onions and cook, stirring, until soft and browned, about 15 minutes. Add the potatoes and stir gently just to combine the two.

Transfer the potatoes and onions to a warmed platter or bowl. Serve immediately. Serves 8.
