Creating a Crispy Chicken Caesar Sandwich at home is straightforward when you follow these simple steps:

1. Marinate Chicken: Start by placing the chicken breasts in a bowl with the buttermilk. Allow them to marinate for at least 30 minutes in the refrigerator. (If time is short, even 10 minutes will help!)
2. Prep Coating: In a shallow dish, combine the breadcrumbs, grated Parmesan cheese, garlic powder, onion powder, paprika, salt, and pepper.
3. Coat Chicken: Remove the chicken from the buttermilk, allowing any excess to drip off. Dredge the chicken in the breadcrumb mixture until well coated.
4. Heat Oil: In a large skillet, heat about ½ inch of olive oil over medium-high heat. Make sure it’s hot enough so the chicken sizzles when added.
5. Fry Chicken: Carefully place the coated chicken breasts in the skillet. Fry for 4-5 minutes per side until they’re golden brown and crispy. Use a meat thermometer to ensure they reach an internal temperature of 165°F (75°C).
6. Drain Excess Oil: Once cooked, remove the chicken from the skillet and let it drain on a paper towel to remove excess oil.
7. Assemble Sandwich: Toast the burger buns lightly. On the bottom half of each bun, layer the shredded Romaine lettuce, sliced crispy chicken, Caesar dressing, and top with croutons if using. Finish with the top half of the bun.
8. Serve: Cut the sandwiches in half if desired and serve immediately. Enjoy the delicious flavors!
