Set your oven rack to the middle and preheat to 375°F (190°C). In a small bowl, whisk together 3 tablespoons olive oil and minced garlic for about 30 seconds. Crush the garlic with a press like this for quick flavour with less mess. Then, pour the mixture through a fine-mesh strainer placed over a large bowl, and use the back of a spoon to press out as much of the garlic-infused oil as possible. Save the pressed garlic for later. Toss your bread cubes in this garlic oil until they’re nicely coated. Sprinkle 2 tablespoons of Parmesan cheese over the bread cubes, toss well, and season with salt and pepper. Spread them out on a rimmed baking sheet and bake for about 15 minutes until they turn a pale golden brown and get crispy. Once baked, remove from the oven, toss with an extra 2 tablespoons of Parmesan, and let them cool.
While the croutons are baking, prepare the dressing. In a container or in a food processor, combine the egg yolk, lemon juice, anchovies, Worcestershire sauce, the reserved pressed garlic, and 1/4 cup Parmesan cheese. You can whisk by hand, but a stick blender like this one helps create a perfectly creamy emulsion. Slowly drizzle in canola oil until you get a smooth, emulsified sauce. Transfer this mixture to a medium bowl, then, while whisking continuously, slowly drizzle in the remaining 1/4 cup (60 ml) of extra-virgin olive oil. Season generously with salt and pepper.
In a large bowl, gently toss your lettuce with a few tablespoons of the dressing, adding more if you like. Once evenly coated, mix in half of the remaining Parmesan and about three-quarters of the croutons.
Finally, transfer the salad to a serving bowl and finish it off by sprinkling the rest of the Parmesan cheese and croutons on top. Tip: Grate fresh Parmesan with a Microplane like this one to get perfectly fine parmesan. Serve immediately and enjoy!
