  • Olive oil
  • Red wine vinegar
  • Smoked paprika
  • Salt

Blend everything until silky smooth and set aside for later.

Step 2: Prepare The Chicken For Maximum Crispiness

This helps them cook quickly and evenly.

Step 3: Create Your Crispy Coating Station

Set up three separate bowls:
  • First bowl: Flour mixed with salt and black pepper
  • Second bowl: Beaten eggs
  • Third bowl: Panko breadcrumbs combined with Parmesan cheese

Step 4: Coat And Dredge The Chicken

Dip each chicken fillet first in flour, then eggs, and finally roll in the panko-Parmesan mixture.

Ensure each piece is completely covered for ultimate crunchiness.

Step 5: Fry To Golden Perfection

Heat olive oil in a large skillet over medium heat.

Fry chicken fillets until they turn a gorgeous golden brown, about 3 minutes per side.

Step 6: Finish In The Oven

Bake for 8-10 minutes until chicken reaches an internal temperature of 165°F.

Top with the second bun half and serve immediately while everything is warm and crispy.

Simple Tips For Crispy Grilled Chicken Sandwich With Smoky Romesco Sauce

  • Swap breadcrumbs for gluten-free alternatives like almond meal or cornmeal to make the sandwich celiac-friendly. Use a digital meat thermometer to ensure chicken reaches exact internal temperature without overcooking. Pat chicken breasts completely dry before coating to help breading stick perfectly and create extra crispy exterior. For added flavor variation, experiment with different nuts in romesco sauce like walnuts or pistachios instead of traditional almonds. Keep oil temperature consistent while frying to prevent chicken from absorbing excess grease and maintain optimal crunchiness.

  • Spicy Jalapeño Romesco Sandwich: Add diced jalapeños to the romesco sauce and mix crushed red pepper flakes into the breading for a fiery kick.
  • Pesto Chicken Fusion Sandwich: Swap romesco sauce with homemade basil pesto and add fresh mozzarella slices for an Italian-style transformation.
  • Southern Buttermilk Chicken Sandwich: Marinate chicken in buttermilk before breading and use cornmeal in the coating for a crispy southern-style texture.

Great Pairings For Crispy Grilled Chicken Sandwich With Smoky Romesco Sauce

  • Pair with Crisp White Wine: Enjoy a chilled sauvignon blanc or albariño to complement the smoky romesco sauce and cut through the richness of the crispy chicken.
  • Match with Zesty Craft Beer: Select a hoppy IPA or wheat beer with citrus notes that will enhance the sandwich's crispy texture and bright arugula flavor.
  • Create a Mediterranean-Inspired Side: Serve with a light Greek salad featuring cucumber, feta, and kalamata olives to echo the romesco sauce's Spanish roots and add refreshing contrast.
  • Elevate with Tangy Pickle Accompaniment: Add homemade quick-pickled vegetables or dill pickle spears to provide a sharp, acidic balance against the creamy, crispy chicken sandwich.

How To Keep Crispy Grilled Chicken Sandwich With Smoky Romesco Sauce Fresh

  • Refrigerate: Store leftover chicken sandwiches in an airtight container for up to 2 days, separating the bun from the chicken to prevent sogginess.

  • Reheating Oven Method: Preheat oven to 350°F, place chicken on a wire rack, and warm for 10-12 minutes until crispy and heated through. Avoid microwave to maintain crunchiness.
  • Toasting Buns: Quickly refresh bread by lightly toasting in a skillet or toaster oven before reassembling the sandwich, ensuring a crisp texture and warm bread.
