This Crispy Chicken Romesco Sandwich turns an ordinary chicken sandwich into something remarkable. After tweaking this dish many times, I've found that what makes it stand out is the interplay between the crunchy chicken and the nutty, thick romesco sauce, all complemented by the bright, tangy salad.
I brought these to an outdoor gathering last week, and nobody could believe how the romesco sauce transformed a basic chicken sandwich. What's the trick? Spending enough time coating the chicken properly and allowing the romesco flavors to mix together fully.
Key Ingredients and Their Purpose
- Roasted red peppers: Give sweetness and richness to the romesco base
- Focaccia: Its fluffy texture and olive oil taste works great with the fillings
- Panko breadcrumbs: Makes a better crunch than standard breadcrumbs
- Fresh herbs: Add brightness to everything
- Sun-dried tomatoes: Supply rich umami notes to the sauce

Step-by-Step Cooking Guide
- Nailing the Chicken Prep
- Flatten chicken to the same thickness so it cooks evenly. Add salt and pepper to breadcrumbs. Keep one hand for wet stuff, one for dry stuff during coating. Don't put too many pieces in the pan when frying.
- Getting the Romesco Right
- Lightly brown nuts before mixing for better taste. Pour in liquid bit by bit for just the right thickness. Keep tasting and tweaking seasonings. Let the sauce sit so flavors can blend.
- Smart Assembly
- Heat bread right before putting everything together. Stack ingredients carefully for a solid sandwich. Put salad on at the end to keep it crunchy. Wrap in paper for clean eating.

After trying different approaches, I've learned that making more romesco sauce than needed is always smart - it tastes amazing on everything from veggies to grilled meats.
This sandwich hits all the right notes with its mix of textures and flavors. The way the crunchy chicken works with the smooth romesco while the fresh salad adds brightness makes a sandwich that's both satisfying and fancy.
Prep-Ahead Friendly Approach
Set up components for quick assembly:
Mix up romesco sauce up to 5 days in advance
Whip up garlic butter and keep it refrigerated
Cook chicken beforehand and warm in oven to bring back crispiness
Clean and dry greens ahead of time
Fixing Common Problems
From lots of sandwich-making sessions, here are some fixes:
For chicken that's not crispy enough: Use two coats of breadcrumbs
For romesco that's too thick: Add a bit more olive oil
For bread that gets mushy: Toast it longer
For wilting salad: Only add dressing when you're ready to eat
