• 2 tbsp finely chopped fresh chives
• Kosher salt and freshly ground black pepper, to taste

For the Bacon and Warm Vinaigrette

• 6 oz (170 g) thick-cut bacon or slab bacon, cut into 1/2-inch lardons
• 3 tbsp reserved bacon drippings (from cooking the lardons)
• 1 large shallot (about 1/3 cup; 50 g), finely minced
• 3 tbsp red wine vinegar (45 ml)
• 2 tsp Dijon mustard (10 g)
• 1/2 tsp sugar or honey, to balance acidity
• 1 tbsp olive oil (15 ml)
• Freshly ground black pepper and a pinch of kosher salt, to taste

For the Poached Eggs

• 4 large eggs
• 1 tbsp white vinegar, for poaching water
• 1 tsp kosher salt, for poaching water

Step-by-Step Instructions

Step 1: Make the Croutons

Heat the oven to 375°F (190°C). Toss the baguette cubes with 1 1/2 tablespoons olive oil and a pinch of kosher salt on a sheet pan. Spread in a single layer and bake on the center rack for 8–10 minutes, stirring once halfway through, until golden and crisp. Set aside to cool.

Step 2: Prep the Frisée

Separate frisée leaves, discard any very tough cores, and tear into bite-size pieces. Rinse well, then dry thoroughly in a salad spinner and on towels—dry leaves are essential so the vinaigrette clings instead of puddling. Keep chilled until assembly.

Step 3: Cook the Bacon Lardons

Place the bacon lardons in a large skillet over medium heat. Cook, stirring occasionally, until browned and crisp, 8–10 minutes. Transfer bacon to a paper towel–lined plate. Carefully pour drippings into a heatproof measuring cup and reserve 3 tablespoons for the vinaigrette (discard or save the rest for another use).

Step 4: Poach the Eggs

Bring 2–3 inches of water to a bare simmer (about 185–190°F / 85–88°C) in a wide saucepan. Add 1 tablespoon white vinegar and 1 teaspoon kosher salt. Crack each egg into a small cup. Swirl the water gently to create a slight vortex, then slide in each egg. Poach 3–4 minutes for a runny yolk (longer for firmer). Remove with a slotted spoon to a paper towel–lined plate to drain.

Step 5: Build the Warm Bacon Vinaigrette

Return 3 tablespoons reserved bacon drippings to the skillet over low heat. Add the minced shallot and cook until softened and translucent, 1–2 minutes. Whisk in the red wine vinegar, Dijon, and sugar until emulsified, then whisk in 1 tablespoon olive oil. Season generously with black pepper and a pinch of salt. Keep warm over the lowest heat; avoid boiling.

Step 6: Toss the Salad

Place the frisée in a large mixing bowl. Pour over the warm vinaigrette and add half the crispy bacon. Toss gently for 15–30 seconds until the leaves are just coated and lightly wilted. Add half the croutons and toss once more. Taste and adjust seasoning with salt and pepper.

Step 7: Plate and Garnish

Divide the salad among 4 shallow bowls. Top each with a poached egg. Scatter on the remaining bacon and croutons, and sprinkle with chopped chives and a few extra grinds of black pepper. Serve immediately so the warm vinaigrette and runny yolk glaze the greens.

Pro Tips

• Dry greens thoroughly—water on frisée will dilute the vinaigrette and make the salad soggy.
• Use slab bacon for evenly sized lardons; they cook uniformly and look great on the plate.
• Keep the vinaigrette warm, not hot. Overheating can scorch the shallots or toughen the greens.
• Poach eggs ahead: chill in ice water, then rewarm in hot (not boiling) water for 45–60 seconds before serving.
• Balance to taste. Add a pinch more sugar for sharp vinegar, or a splash more vinegar if it tastes too rich.

Variations

• Chicory mix: Swap part of the frisée with endive or radicchio for a deeper bitter bite and color contrast.
• Pancetta twist: Use diced pancetta instead of bacon for a slightly sweeter, porky flavor.
• Garlic croutons: Toss bread cubes with a smashed garlic clove and olive oil before toasting for extra aroma.

Storage & Make-Ahead

Salade Lyonnaise is best assembled and eaten immediately. Store components separately: croutons in an airtight container at room temperature for up to 3 days; cooked bacon refrigerated up to 3 days; vinaigrette refrigerated up to 3 days (reheat gently until warm, whisking to re-emulsify); poached eggs can be held in cold water in the refrigerator up to 24 hours and rewarmed in hot water for 45–60 seconds. Do not store the dressed salad—greens will wilt and turn soggy.
