Potato Lyonnaise with crispy bacon and leeks, ready to serve
Ingredients You Will Need
About 3 cups of pre-boiled small potatoes (small red, Yukon gold, fingerlings, or similar), chilled
1 thick slice of bacon
1 leek, split and thoroughly washed
1 small onion or shallot
2 or 3 oven-dried or sun-dried tomatoes
1 cup white wine, divided
2 sprigs of fresh thyme
2 tablespoons butter
Salt and pepper to taste
Pre-boiling the potatoes ahead of time and keeping them chilled in your fridge is the key to speeding up this recipe. This step is especially useful if you want to prepare this dish during a cooking class or a busy weeknight in Chicago.
Step-by-Step Cooking Instructions
1. Render the Bacon
Start by heating a pan over low to medium heat. Place the thick slice of bacon in the pan and cook it slowly. This process allows the bacon to render its fat and become crispy without burning. The bacon fat will provide a flavorful base for the rest of the dish.
While the bacon cooks, prepare your vegetables.
2. Prepare the Vegetables
Thinly slice the leek
Thinly slice the onion or shallot
Slice the sun-dried tomatoes into medium pieces
Once the bacon is crispy and most of the fat is rendered, remove the slice from the pan and set it aside. Cut the bacon into small batons or bite-sized pieces.
3. Cook the Onion
Add the sliced onion to the bacon fat in the pan. Cook over medium heat until the onion softens and browns slightly. This step adds sweetness and depth to the dish.
4. Add the Potatoes
Add the chilled, pre-boiled potatoes to the pan. Stir them gently to coat with the bacon fat and onion mixture. This will help the potatoes absorb the flavors and start to brown.
5. Incorporate Leeks, Wine, and Butter
Add the sliced leeks, half of the white wine (½ cup), and 1 tablespoon of butter to the pan. Cook over medium heat until the leeks soften and the wine reduces almost completely. If the wine isn’t reducing fast enough, increase the heat slightly but watch carefully to avoid burning.
6. Add Bacon, Tomatoes, and Thyme
Return the bacon pieces to the pan. Add the sliced sun-dried tomatoes and strip the leaves from the thyme sprigs, stirring them in. The thyme adds a fresh herbal note that complements the richness of the bacon and potatoes.
7. Finish with Remaining Wine and Butter
Pour in the remaining ½ cup of white wine and add the last tablespoon of butter. Increase the heat to medium-high and cook until the liquid reduces and coats all the ingredients with a glossy finish. Season with salt and pepper to taste.
Tips for Perfect Potato Lyonnaise
Use a mix of small potatoes like red, Yukon gold, and fingerlings for varied texture and color.
Pre-boil potatoes a day ahead and chill them to save time during cooking.
Choose thick-cut bacon for better flavor and texture.
If you’re attending a cooking class in Chicago, ask the instructor for tips on selecting the best white wine for cooking.
Oven-dried tomatoes add a concentrated sweetness; if unavailable, sun-dried tomatoes soaked in warm water work well too.
Serving Suggestions
Potato Lyonnaise pairs beautifully with quiche, roasted chicken, or grilled fish. It also works well as a hearty side for brunch or dinner. The crispy bacon and tender leeks make it a crowd-pleaser at any meal.
If you’re looking to impress guests or simply enjoy a comforting dish, this recipe fits the bill. It’s quick enough for weeknights but elegant enough for special occasions.
