This Crispy Chicken Romesco Sandwich turns an ordinary chicken sandwich into something truly memorable. After tweaking this dish many times, I've found that the real wow factor comes from the interplay between the super crunchy chicken and the thick, nutty romesco sauce, all complemented by a bright, tangy salad mix.
I brought these to an outdoor gathering recently, and everyone couldn't believe how the romesco totally transformed a basic chicken sandwich. What's the trick? Taking care with the chicken coating process and giving the romesco time to develop its full flavor profile.
Key Ingredients and What They Do
- Panko crumbs: They give you way better crunch than standard breadcrumbs
- Roasted red peppers: They create the romesco foundation with their sweet, rich taste
- Focaccia: Its puffy texture and olive oil flavor works perfectly with the fillings
- Sun-dried tomatoes: They pack intense flavor into the sauce
- Fresh herbs: They add brightness to everything

Step-by-Step Cooking Guide
- Chicken Done 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 during coating. Don't put too many pieces in the pan when you're frying.
- Getting Romesco Just Right
- Lightly brown the nuts before blending for richer taste. Pour in liquid bit by bit for the perfect texture. Keep tasting and tweaking seasonings. Let the sauce sit so flavors can mingle.
- Putting It All Together
- Get your bread toasted right before you build the sandwich. Stack ingredients in the right order for a stable sandwich. Put the greens on top to keep them crisp. Wrap in paper for clean eating.

Through lots of testing, I've learned that making more romesco sauce than you need is always smart. It goes great with just about anything from roasted veggies to grilled meat.
This sandwich hits all the right notes. The way the crunchy chicken works against the smooth romesco while the fresh salad brings brightness creates something that's both down-to-earth and fancy at once.
Prepping Components Ahead
Set up the parts for easy sandwich building:
Make your romesco up to 5 days in advance
Mix up garlic butter and keep it in the fridge
Cook chicken earlier and warm in the oven to bring back the crunch

Fixing Common Problems
After making tons of these sandwiches, here's what works:
For chicken that's not crunchy enough: Apply two layers of breadcrumbs
For romesco that's too thick: Add a bit more olive oil
For soggy bread: Toast it longer
For wilting greens: Only add dressing right at serving time
