Whisk the first 11 ingredients together in a bowl. Heat the 1/4 cup of olive oil in a large skillet over medium-low. Add baguette cubes and cook, turning occasionally, until lightly toasted, about 5 to 6 minutes. (If you do not have a large skillet, use 2 medium-sized ones.) Toss in 1/2 the Parmesan cheese, then remove from the heat. Toss the lettuce, croutons and remaining Parmesan with the dressing. Serve plates of the salad, if desired, with lemon wedges.
Recipe Options: The dressing can be made up to two days in advance and kept stored in the fridge in a tight-sealed container until needed. For an iron-rich Caesar salad, use an equally amount of baby spinach leaves instead of chopped romaine. Make the salad less or more sharper tasting by increasing or decreasing the amount of lemon and vinegar used. Instead of baguette, use other breads to make the croutons, such as foccacia or filone.
