Ingredients
- 2 heads frisée or curly endive, torn into pieces
- 6 oz (170 g) thick-cut bacon or lardons, diced
- 4 large eggs
- 2 tablespoons white vinegar
- 2 tablespoons Dijon mustard
- 1 tablespoon red wine vinegar
- 1 small shallot, finely minced
- 1/3 cup extra-virgin olive oil
- 1 teaspoon sugar
- Salt and black pepper to taste
- 1/4 cup chopped fresh chives
- Sourdough croutons, to serve
Instructions
- Whisk the Dijon, red wine vinegar, shallot, sugar, salt, and pepper in a small bowl. Whisk in the olive oil until emulsified.
- Cook the bacon in a skillet over medium heat for 6 to 7 minutes until crisp and golden. Remove the bacon and reserve the fat in the pan.
- Warm the vinaigrette in the bacon fat over low heat for 1 minute, whisking, until just warm — do not boil it.
- Bring a pot of water to a gentle simmer with the white vinegar. Swirl the water, slip in the eggs one at a time, and poach for 3 minutes until the whites are set and the yolks are runny.
- Place the frisée in a large bowl. Pour the warm vinaigrette over it and toss gently so the leaves wilt slightly.
- Divide among plates, top each with the crisp bacon, a poached egg, and croutons.
- Sprinkle with chives and black pepper and serve immediately while the egg is warm and runny.
Pro tips
- Warm the vinaigrette in the bacon fat — it is the secret to the salad's rich, smoky flavor.
- Poach the eggs just before serving so the yolks are still runny.
- Toss the frisée with the warm dressing so the leaves wilt slightly and absorb the flavor.
- Use frisée if you can find it; its bitter bite balances the rich egg and bacon.
Frequently asked questions
What is salad lyonnaise?
A warm bistro salad from Lyon, France, made with frisée lettuce, bacon lardons, a poached egg, and a warm mustard vinaigrette. It is a classic French starter.
Can I use a different lettuce?
Yes — escarole or a sturdy mixed green works, but frisée's bitter crunch is traditional and balances the rich toppings.
How do I poach an egg perfectly?
Use very fresh eggs, simmer (never boil) the water with a splash of vinegar, and cook for 3 minutes for a runny yolk.
Can I make salad lyonnaise ahead?
Prep the bacon, vinaigrette, and greens ahead, but poach the eggs and toss the salad just before serving.
