Step-by-Step Instructions

Step 1: Simmer the lentils with aromatics

Combine the lentils, water (or broth), salt, bay leaf, thyme, carrot, celery, and smashed garlic in a medium pot. Bring to a boil over high heat, then reduce to maintain a gentle simmer at about 190°F/88°C. Cook until the lentils are tender but still hold their shape, 22–28 minutes. Reserve 1/2 cup (120 ml) of the cooking liquid, then drain the lentils and discard the aromatics. Keep the lentils warm.

Step 2: Crisp the lardons

While the lentils cook, place the lardons in a large skillet over medium heat. Cook, stirring occasionally, until the fat renders and the lardons are deeply golden and crisp, 7–9 minutes. Transfer the lardons to a paper towel–lined plate. Pour off all but 1 tablespoon of the drippings from the skillet and reserve an additional 1 tablespoon of warm drippings for the vinaigrette.

Step 3: Sauté the shallots

Return the skillet (with 1 tablespoon drippings) to medium heat. Add the 3 sliced shallots and a pinch of salt. Cook, stirring, until softened and lightly caramelized at the edges, 4–6 minutes. Remove from heat and set aside in the skillet to keep warm.

Step 4: Whisk the warm Dijon–shallot vinaigrette

In a small bowl, whisk the red wine vinegar, Dijon mustard, honey, the finely minced shallot, 1/4 teaspoon salt, and 1/2 teaspoon black pepper. Slowly whisk in 1 tablespoon warm bacon fat and 2 tablespoons olive oil until emulsified. Whisk in 1–2 tablespoons hot lentil cooking liquid to make a loose, glossy dressing.

Step 5: Toss the lentils and season

Add the warm drained lentils to the skillet with the sautéed shallots. Pour over about two-thirds of the vinaigrette, add the parsley, chives, half the lardons, and another few grinds of black pepper. Toss gently over low heat for 1–2 minutes to warm through. Taste and adjust salt, pepper, and vinaigrette as needed.

Step 6: Poach the eggs

Bring 2 quarts (2 L) of water to 180–190°F (82–88°C) in a medium saucepan—steaming hot but not boiling. Add 1 tablespoon white vinegar and a pinch of salt. Crack each egg into a small cup. Swirl the water to create a gentle vortex, then slide in an egg. Repeat with remaining eggs, spacing them out. Poach 3 minutes for runny yolks or up to 4 minutes for slightly firmer centers. Lift with a slotted spoon, blot on a clean towel, and trim wispy edges if desired.

Step 7: Plate and finish

Divide a handful of frisée (if using) among warm shallow bowls. Spoon the warm lentils over the greens. Top each portion with a poached egg, scatter over the remaining lardons, and drizzle with any remaining vinaigrette. Finish with flaky salt and plenty of freshly cracked black pepper. Serve immediately while everything is warm and glossy.

Pro Tips

• Keep the simmer gentle. A rolling boil can split the lentils and make them mushy.
• Salt early, then adjust. Lentils taste flat without salt; start with 1 teaspoon in the pot, then season again after dressing.
• Warm dressing, warm lentils. Tossing everything warm helps the vinaigrette soak in for maximum flavor.
• Poach below a boil. 180–190°F water gives delicate, shapely poached eggs without ragged whites.
• Pre-warm bowls. Hot bowls keep the lentils and egg at a perfect serving temperature.

Variations

• Vegetarian Lyonnaise: Swap lardons for 8 oz (225 g) mixed mushrooms, sautéed in 2 tablespoons olive oil with a pinch of smoked paprika for a hint of “bacon” flavor.
• Frisée-forward: Toss 3 cups frisée with 1–2 tablespoons vinaigrette and mound under the lentils for a bistro-style salad feel.
• Herb twist: Add 1 teaspoon finely chopped fresh tarragon to the vinaigrette for a classic French note.

Storage & Make-Ahead

Cooked lentils (dressed or undressed) keep 4 days in the refrigerator. For best texture, store lentils and vinaigrette separately and combine when reheating. Rewarm lentils gently with a splash of water in a skillet over low heat. Lardons stay crisp up to 2 days; recrisp briefly in a pan. Poach eggs up to 24–48 hours ahead: chill immediately in ice water and store submerged in the fridge. To serve, slip eggs into 150–160°F (65–71°C) water for 45–60 seconds to rewarm, then drain and plate.
