Lyonnaise salad is a classic French salad. It typically features frisée lettuce, lardons (thin strips of bacon), and a warm dressing made with red wine vinegar, Dijon mustard, shallots, and olive oil. The salad is often topped with croutons and a poached egg.
First, cook the lardons in a large skillet over medium heat until crispy. Drain on paper towels.
In a small bowl, whisk together the red wine vinegar, Dijon mustard, honey, shallot, salt, and pepper.
Bring a pot of water to a boil and gently add eggs. Cook for 6 minutes. Remove from water and place into a bowl of ice water to stop cooking process.
In a large bowl, toss the frisée with the olive oil and the vinaigrette. Season with salt and pepper.
Divide the salad among four plates. Top each salad with a quarter of the crispy lardons, a quarter of the croutons, and a quarter of the sliced boiled eggs. Serve immediately.
