Step 1

Preheat oven to 450 degrees and adjust oven rack to the middle position. Prepare a rimmed baking sheet with parchment paper. In a small bowl, whisk together the olive oil, garlic powder, Italian seasoning, and salt.

Step 2

Add bread pieces to a very large bowl and toss with olive oil mixture until well combined. Evenly spread croutons on prepared sheet and bake until golden brown, about 10 to 15 minutes. Cool completely.

Step 3

In a food processor, add egg and process until frothy, about 10 seconds. Add garlic, Parmesan cheese, white balsamic vinegar, red wine vinegar, Dijon, spicy brown mustard, anchovies, 1 1/2 teaspoon salt, and 1/2 teaspoon pepper, and pulse until well combined.

Step 4

While the processor is on, slowly drizzle in olive oil to create the emulsion. Season to taste with salt and freshly ground black pepper.

Step 5

Add chopped romaine to a large bowl, drizzle with Caesar dressing. Sprinkle with 1/2 cup (or more) or Parmesan cheese and croutons. Toss to combine. Serve with additional Parmesan cheese as garnish.
