Step 1: Preheat the oven to 190°C. Toss bread cubes with olive oil, garlic powder, and salt. Spread on a baking tray and bake for 10–12 minutes, turning once, until golden and crisp.
Step 2: In a bowl, toss shrimp with olive oil, garlic powder, paprika, salt, and black pepper.
Step 3: Heat a skillet over medium-high heat. Cook shrimp for 2–3 minutes per side until pink and opaque. Remove from heat and set aside.
Step 4: In a small bowl, whisk together mayonnaise, garlic, lemon juice, Dijon mustard, Parmesan, Worcestershire sauce, and black pepper to make the dressing.
Step 5: In a large bowl, combine romaine lettuce with dressing and toss gently to coat.
Step 6: Top the salad with cooked shrimp, crispy croutons, and extra Parmesan cheese.
