0.5 tsp black pepper – freshly ground (for dressing)
2 hearts romaine lettuce – leaves separated and dried very well
Parmigiano Reggiano – shaved (for serving)
black pepper – freshly ground (for serving)
Instructions
Preheat the oven to 375°F. Line a rimmed baking sheet with parchment.
Toss the country bread, extra-virgin olive oil (for croutons), garlic (for croutons), and kosher salt (for croutons) on the sheet until evenly coated. Bake, tossing once halfway, until golden and crisp, 12–15 minutes. Cool on the sheet for 5 minutes.
Prepare the romaine lettuce by separating the leaves, tearing into large pieces, and drying thoroughly in a spinner or on towels until no visible moisture remains, about 5 minutes. Chill while you make the dressing.
On a cutting board, mash the anchovy fillets and garlic (for dressing) together with a pinch of the kosher salt for dressing using the side of a knife until a smooth paste forms, 30–60 seconds.
In a large mixing bowl, whisk the egg yolk, Dijon mustard, Worcestershire sauce, lemon juice, and the anchovy–garlic paste until smooth and slightly thick, about 1 minute.
While whisking constantly, slowly drizzle in the extra-virgin olive oil (for dressing) until the dressing is thick, glossy, and emulsified, 3–4 minutes.
Whisk in the finely grated Parmigiano Reggiano, the remaining kosher salt (for dressing), and black pepper (for dressing) until combined, 30 seconds; the dressing should taste savory, garlicky, and bright.
Add the prepared leaves to the bowl and toss until evenly coated and glossy, 30–60 seconds.
Add the croutons and toss briefly to coat without softening them, 10–15 seconds.
Plate and finish with Parmigiano Reggiano shaved (for serving) and black pepper (for serving). Serve immediately while crisp.
