Cooking Method

The traditional method is in a skillet on the stove. They are par boiled then sauteed in butter in on the stove. This lyonnaise potatoes recipe first par boils the potatoes, then cooks them with duck fat in the oven to get them crispy. I find baking them in the oven eliminates the mess of pan frying.

Difference Between Lyonnaise Potatoes and Dauphinoise Potatoes

Lyonnaise potatoes are typically sautéed in butter and garlic, while Dauphinoise potatoes are typically cooked in cream.

Why This Recipe Works

1. The use of duck fat adds an amazing deep richness to the potatoes. Plus it helps them to crisp up nicely.
2. Crisping them in the oven is much neater than frying them on the stove top. Plus, it's more hands off.

Step By Step Instructions

Preheat the oven to 425 degrees. We want our potatoes sliced thin, so I recommend using a mandolin to slice them about ¼-1/8" thick.

Then we parboil the potatoes to remove some of the extra starchiness. Parboiling makes it easier to get the nice crisp potato we are after.

Bring the water to a boil and add the potatoes. Cook for 1-2 minutes (depending on thickness of the potatoes) and drain thoroughly.

Layer the potatoes on a baking sheet and cover them with the duck fat. It may be easier to melt the duck fat for this step so you can drizzle it on. Bake them in the oven for 20 minutes.

While your potatoes are baking, heat the butter in a sauce pan over medium heat and add the onions.

Cook the onions for about 5-10 minutes, stirring periodically, until they are softened and golden brown.

We don't want to totally caramelize them, just turn them golden brown so the sweetness starts to come out. Our goal is to bring out just a little of the sweetness from the onions, but still leave them intact.

After your potatoes have been cooking for 20 minutes, remove from the oven and cover with the cooked onions and chopped garlic.

Place them back in the oven for 10 minutes. Remove them from the oven and sprinkle them with crushed red pepper and a drizzle of fresh lemon juice while still hot.

Expert Tips

1. Use Russet potatoes because they will crisp up the best.
2. Use a mandolin to ensure the potatoes are sliced thin enough.
3. The duck fat can be substituted with butter, cooking oil (not as good flavor), bacon fat, etc.
4. Be careful not to overcook the potatoes while par boiling. They should only be cooked for 1-2 minutes.
5. If potatoes are not crisp enough, pop them under the broiler for a couple minutes - be careful not to let them burn.
6. The onions should be soft and golden brown - we don't want to totally caramelize them, just cook them long enough to bring out the sweetness.
7. Add more or less crushed red pepper depending on your spice preference.
