Creating a Crispy Chicken Caesar Sandwich is easy if you follow these steps:

1. Marinate Chicken: In a bowl, add the chicken breasts and cover them with buttermilk. Let them marinate in the fridge for at least 30 minutes.
2. Prepare Coating: In a separate bowl, combine flour, garlic powder, onion powder, paprika, salt, and pepper.
3. Set Up Breading Station: Prepare breadcrumbs in a third bowl.
4. Bread the Chicken: Remove the marinated chicken from the buttermilk. Dredge each piece in the seasoned flour, shaking off excess, then dip in breadcrumbs.
5. Heat Oil: In a skillet, add enough olive oil to cover the bottom. Heat over medium-high heat until hot.
6. Fry Chicken: Add the chicken to the skillet and cook for 5-7 minutes on each side, or until golden brown and cooked through. Use a meat thermometer; the internal temperature should reach 165°F (74°C).
7. Drain and Rest: Remove from the skillet and place the chicken on a plate lined with paper towels to drain any excess oil. Allow resting for a few minutes.
8. Toast Buns: While the chicken is resting, slice the sandwich rolls in half and toast them lightly in the skillet or in an oven.
9. Assemble the Sandwich: Spread Caesar dressing on the bottom bun, add the crispy chicken, followed by chopped romaine lettuce, and drizzle more dressing on top.
10. Add Cheese: Sprinkle with grated Parmesan cheese before placing the top bun on the sandwich.

These steps will lead you to a crispy, flavor-packed sandwich that’s sure to impress.
