This Crispy Chicken Romesco Sandwich takes your average chicken sandwich to a whole new level. After tweaking this dish many times, I've found that what makes it shine is the interplay between the super crunchy chicken and the nutty, thick romesco sauce, all complemented by a zesty, fresh salad mix.
I brought these to a get-together last week, and nobody could believe how the romesco turned a basic chicken sandwich into something special. The trick? Taking your time with the chicken coating and letting the sauce flavors come together properly.
Key Ingredients and What They Do
- Sun-dried tomatoes: Give the sauce a deep, savory kick
- Fresh herbs: Add brightness to every part of the sandwich
- Focaccia: Works perfectly with the fillings thanks to its oil-infused, fluffy structure
- Roasted red peppers: Create sweetness and richness in the romesco base
- Panko breadcrumbs: Make a way better crunch than standard breadcrumbs

Step-by-Step Cooking Guide
- Assembly Strategy
- Toast your bread right before putting everything together. Stack ingredients in a way that keeps the sandwich stable. Put the salad in last so it stays crisp. Wrap in parchment paper for a clean eating experience.
- Getting the Chicken Just Right
- Flatten chicken to make it cook evenly. Add some salt and pepper to your breadcrumbs. Keep one hand for wet stuff and one for dry when coating. Don't try to cook too many pieces at once.
- Making Great Romesco
- Lightly toast the nuts first for better flavor. Pour in liquid bit by bit to get the texture right. Keep tasting and tweaking as you go. Let it sit a while so flavors can blend.

I've learned through trial and error that making more romesco sauce than you need is always smart. It tastes fantastic on everything from roasted veggies to grilled meat dishes.
This sandwich has everything working together perfectly. The way the crunchy chicken works with the smooth romesco while the fresh salad adds a light touch makes something that's both fancy and totally satisfying.
