Pin it
I started making this sandwich after a trip to a small tapas bar where romesco was served with everything. The sauce is smoky and rich, and it needs something crunchy to stand up to it. Crispy panko chicken and chewy focaccia turned out to be the answer.
This is not a light lunch. It is a two-handed, napkin-required sandwich with real texture in every bite. The chicken stays crisp even after you spoon on the warm romesco, and the arugula adds just enough peppery bite to balance the richness.
What builds this stack
Quality matters here. Use good jarred roasted red peppers, not the pickled kind, and real blanched almonds for the smoothest sauce. A bakery focaccia with dimples and a little olive oil on top will hold up better than sandwich bread.
- Chicken breasts. Pounded thin so they cook fast and evenly without drying out.
- Panko breadcrumbs. Lighter and crunchier than standard breadcrumbs, they stay crisp under the sauce.
- Roasted red peppers. The base of romesco. Jarred fire-roasted peppers save time and taste great.
- Blanched almonds. They thicken the sauce and add a mellow nuttiness without skins getting in the way.
- Smoked paprika. This is where the depth comes from. Do not skip it.
- Focaccia. Soft inside with a chewy crust, it soaks up the romesco without falling apart.
- Arugula and Manchego. Peppery greens and salty cheese round out every bite.
How to build it
- Blend the romesco. Combine roasted peppers, drained tomatoes, almonds, garlic, smoked paprika, sherry vinegar, and olive oil in a food processor. Blitz until smooth and thick. Taste for salt and acid.
- Pound and bread the chicken. Place breasts between plastic and pound to half-inch thickness. Set up a dredging station with flour, beaten eggs, and panko mixed with a pinch of paprika and salt.
- Fry until golden. Heat a thin layer of olive oil in a heavy skillet over medium-high heat. Cook the chicken for three to four minutes per side until deeply golden and cooked through to 165°F.
- Toast the focaccia. Split the focaccia and toast the cut sides in a dry skillet or under the broiler until lightly crisp. This keeps the bread from going soggy.
- Assemble and serve. Spread a generous layer of romesco on the bottom half. Add the chicken, a handful of arugula, and shaved Manchego. Cap with the top half and cut in half.
Keep the crunch
The enemy of a good crunchy chicken sandwich is steam. After frying, let the chicken rest on a wire rack instead of a paper towel or plate. Air circulates underneath and the crust stays shatter-crisp. If you want extra insurance, keep the finished cutlets in a warm oven on the rack while you toast the bread. Panko is the right choice here because its flaky structure fries up lighter than fine breadcrumbs. If you only have regular breadcrumbs, pulse them briefly in a food processor to break them up into a coarser crumb. For another crispy chicken idea, try our Italian basil chicken cutlets.
The five-minute romesco
Traditional romesco can involve roasting your own peppers and toasting bread and nuts separately. This version shortcuts that without losing the soul of the sauce. Jarred fire-roasted red peppers already carry the char you want, and the almonds go straight into the blender raw. The result is still smoky, nutty, and complex. If you have leftover sauce, it keeps in the fridge for five days and works on grilled vegetables, fish, or as a dip. The bread in classic romesco acts as a thickener, but I find a small handful of almonds does the same job while keeping the sauce gluten-free.
Stack it right
Order matters in a saucy sandwich. Always put the romesco on the bottom bread, then the chicken, then the cheese and greens on top. The chicken protects the bottom focaccia from soaking up too much sauce, and the arugula stays perky instead of wilting. If you prefer a melted-cheese situation, lay the Manchego directly on the hot chicken right out of the pan and let it soften for a minute before adding the greens. If Manchego is hard to find, aged provolone or even sharp cheddar works.

Make ahead and store
You can make the romesco up to five days ahead and store it in an airtight container. The chicken is best fried fresh, but you can bread the cutlets a few hours ahead and keep them on a plate in the fridge uncovered. Once assembled, these sandwiches do not store well, so build them just before eating. Leftover fried chicken reheats surprisingly well in a 375°F oven on a wire rack for ten to twelve minutes. The USDA recommends cooking chicken to an internal temperature of 165°F. See the USDA chicken safety guidelines for more details.
What to serve with it
This sandwich is a meal on its own, but a simple side keeps it from feeling too heavy. I like salted potato chips or a quick cucumber salad with red onion and sherry vinegar. A cold sparkling water or a light beer cuts through the richness. If you are feeding a crowd, serve the components separately and let people build their own. It turns lunch into a casual event and the chicken stays crisp until the last minute.
FAQs
- Can I bake the chicken instead of frying?
Yes. Spray the breaded cutlets lightly with oil and bake at 425°F on a wire rack set over a baking sheet for 18-20 minutes, flipping halfway. They will not be quite as golden, but they stay crisp.
- What cheese works best if I cannot find Manchego?
Aged provolone, manchego-style sheep cheese, or even sharp white cheddar all work. You want something salty that can stand up to the smoky sauce.
- Can I use store-bought romesco?
You can, but homemade takes five minutes in a blender and tastes brighter. If you buy it, look for a brand with almonds and smoked paprika in the ingredient list.
- How do I store leftover romesco?
Keep it in an airtight jar in the fridge for up to five days. The olive oil may firm up, so let it sit at room temperature for fifteen minutes before serving, or warm it slightly.
- Is this sandwich spicy?
Not really. Smoked paprika adds depth and a mild warmth, but there is no chile heat unless you add cayenne. For a kick, stir a pinch of cayenne into the sauce.
- Can I make this gluten-free?
Yes. Use gluten-free panko and make sure your focaccia is gluten-free. The romesco itself is naturally gluten-free if you skip the traditional bread thickener.
- What kind of focaccia should I buy?
Plain olive oil focaccia or rosemary focaccia both work well. Avoid overly thick loaves. A half-inch slice is ideal so you can actually fit the sandwich in your mouth.
