This Crispy Chicken Romesco Sandwich takes your basic chicken sandwich to a whole new level. After trying this again and again, I've found that what makes it so good is how the crunchy chicken plays against the rich, nutty romesco sauce, all balanced out with a bright, tangy salad.
I brought these to a gathering last week, and nobody could believe how the romesco sauce turned a regular chicken sandwich into something special. Want to know my trick? Take your time with the chicken breading and let the romesco flavors mix together properly.
Key Ingredients and What They Do
- Panko breadcrumbs: They give you way more crunch than normal breadcrumbs
- Roasted red peppers: They're the main part of the romesco, adding sweetness and richness
- Focaccia: The airy, olive-oily bread works perfectly with the fillings
- Sun-dried tomatoes: They pack a punch of savory flavor in the sauce
- Fresh herbs: They make everything taste lighter and brighter

Step-by-Step Cooking Guide
- Getting Chicken Just Right
- Flatten chicken to make it cook evenly. Add salt and pepper to your breadcrumbs. Keep one hand for wet stuff and one for dry when breading. Don't put too many pieces in the pan at once.
- Getting the Romesco Perfect
- Lightly brown nuts before blending them for better flavor. Pour in liquid bit by bit for the right thickness. Keep tasting and tweaking. Let the sauce sit so flavors can mix.
- Putting It All Together
- Make sure bread is toasted right before you start. Stack ingredients in the right order so the sandwich stays together. Add greens at the end so they stay crisp. Wrap in paper for neat eating.

I've learned through lots of testing that making more romesco sauce than you need is always smart. It tastes great on everything from veggies to grilled meat.
This sandwich hits all the right notes. The way the crispy chicken works with the smooth romesco while the fresh salad adds brightness makes a sandwich that's both cozy and fancy at the same time.
