Making the Crispy Chicken Caesar Sandwich is straightforward when you follow these steps:

1. Prepare the Chicken: Start by preheating your oven to 400°F (200°C). Pat the chicken breasts dry with paper towels.
2. Set Up Breading Station: In three separate bowls, place flour in one, beaten egg in the second, and breadcrumbs mixed with garlic powder, onion powder, salt, and pepper in the third.
3. Bread the Chicken: Dip each chicken breast first into the flour, shaking off excess, then into the egg, and finally into the breadcrumb mixture, coating thoroughly.
4. Bake the Chicken: Place the breaded chicken on a baking sheet lined with parchment paper. Drizzle with olive oil for extra crispiness and bake for 20-25 minutes until golden and cooked through.
5. Assemble the Sandwich: While the chicken is baking, toast the sandwich buns lightly. Spread Caesar dressing on the bottom half of the bun.
6. Add Chicken and Lettuce: Once the chicken is done, slice it if desired and place it on the bun. Top with chopped romaine lettuce and grated Parmesan cheese.
7. Complete the Sandwich: Add any additional toppings like sliced tomatoes or crispy bacon if using. Place the top bun on the sandwich.
8. Serve and Enjoy: Cut in half for easier handling and serve immediately while hot.

By following these easy steps, you’ll have a delicious Crispy Chicken Caesar Sandwich ready to satisfy your cravings.
