Ingredients You’ll Need

This sandwich is all about maximizing flavor and crunch with a handful of thoughtfully chosen ingredients. Each element brings its own magic to the table, from the juicy chicken to the nutty romesco, making every bite unforgettable.

Boneless, skinless chicken breasts: The key to juicy, tender cutlets that fry up crunchy every time—slice them in half for perfect sandwich portions.
Buttermilk: Acts as a marinade, tenderizing the chicken and infusing it with a subtle tang.
Panko breadcrumbs: Provides unbeatable crispiness for that signature sandwich crunch.
All-purpose flour: Creates a base layer so the breading sticks and gets nice and golden.
Eggs: Helps the panko adhere to the chicken, sealing in moisture during frying.
Olive oil: For pan-frying the chicken and making the romesco luscious and glossy.
Roasted red peppers (from a jar): The backbone of the romesco sauce for bold color and sweet, smoky flavor.
Toasted almonds: Add body and richness to the sauce, plus a hint of nuttiness that’s pure magic.
Garlic clove: A flavor powerhouse, just one adds depth and zing to the romesco.
Sherry vinegar (or red wine vinegar): Brings brightness and tang to the sauce, making all the flavors pop.
Smoked paprika: Gives the romesco its delicate smokiness and gorgeous color.
Crusty sandwich rolls: A solid, hearty base to keep all that juicy chicken and sauce contained.
Fresh arugula or baby spinach: For a peppery, green crunch that cuts through the richness.
Tomato slices: Offer juicy freshness and a little bit of sweetness to round it all out.
Kosher salt and black pepper: Essential for seasoning every layer and pulling all the flavors together.

How to Make Crunchy Chicken Romesco Sandwich

Step 1: Marinate Your Chicken

Start by slicing your chicken breasts horizontally for thinner fillets. In a large bowl, whisk together buttermilk with a generous pinch of salt and pepper. Dunk the chicken in, making sure each piece is completely coated. Cover and refrigerate for at least 30 minutes (up to 4 hours) to let the flavors seep in and the chicken to get ultra-tender and juicy.

Step 2: Prep the Romesco Sauce

Pop drained roasted red peppers, toasted almonds, garlic, sherry vinegar, smoked paprika, and olive oil into a food processor. Blitz until mostly smooth but with a bit of texture remaining. Season with salt and a little more vinegar or oil as needed. This vibrant sauce is the heart of the Crunchy Chicken Romesco Sandwich and elevates every bite!

Step 3: Bread the Chicken

Remove the chicken from the marinade, letting the excess drip off. In three shallow bowls, place flour (season with salt and pepper), beaten eggs, and panko. Dip each chicken piece first in flour, then egg, then press into panko, making sure it’s completely coated for maximum crunch.

Step 4: Fry to Crispy Perfection

Heat half an inch of olive oil in a large skillet over medium-high. Once shimmering, fry the chicken fillets for 3 to 4 minutes per side, until deep golden and crunchy. Drain on a wire rack or paper towel-lined plate. This step gives your Crunchy Chicken Romesco Sandwich its irresistible texture.

Step 5: Assemble Your Sandwich

Split your crusty rolls and toast them lightly if desired. Spread a generous layer of romesco on the cut sides. Lay down a crispy chicken fillet, then top with tomato slices, a pile of arugula or spinach, and an extra drizzle of romesco if you’re feeling bold. Close it all up and get ready for serious sandwich bliss.

How to Serve Crunchy Chicken Romesco Sandwich

Garnishes

Sprinkle freshly chopped parsley, an extra shake of smoked paprika, or a few toasted almond slivers over the top for an added wow factor. A squeeze of lemon brings brightness and is just the ticket to tie all these bold flavors together.

Side Dishes

Pair your Crunchy Chicken Romesco Sandwich with crisp oven fries, a simple mixed green salad, or even tangy pickled vegetables for a fresh, punchy complement. Kettle-cooked chips on the side are a classic move, and nobody will say no to a heap of coleslaw.

Creative Ways to Present

Try serving these sandwiches open-faced for a modern twist or slice them into halves or thirds for the perfect party platter. Stack them high with extra greens or a fried egg for brunch, or serve alongside a bowl of gazpacho for a breezy summer meal.

Make Ahead and Storage

Storing Leftovers

If you have leftover sandwiches, store the chicken, romesco sauce, and toppings separately. Keep the chicken in an airtight container in the fridge for up to 3 days to maintain as much crispiness as possible.

Freezing

The crunchy chicken fillets freeze beautifully after frying—let them cool completely, then wrap tightly and store in a freezer-safe bag for up to a month. The romesco sauce can also be frozen in a small container or an ice cube tray for quick thawing.

Reheating

To bring back the crunch, reheat chicken fillets in a 400-degree oven for 8 to 10 minutes until hot and crispy. Thaw and stir the romesco sauce well before spreading, and then assemble your Crunchy Chicken Romesco Sandwich as usual.

FAQs

Can I make the romesco sauce ahead of time?

Absolutely! The sauce keeps well in the fridge for up to 5 days. In fact, making it in advance lets the flavors meld and become even more delicious for your Crunchy Chicken Romesco Sandwich.

Is there a gluten-free option for this sandwich?

Yes, just swap in gluten-free flour and gluten-free panko or crushed rice crackers for breading. Use gluten-free rolls to build your Crunchy Chicken Romesco Sandwich, and you’re good to go!

What’s the best way to slice the chicken for even frying?

For uniform cooking and the perfect sandwich size, carefully slice each chicken breast in half horizontally to create thinner fillets—this helps them cook quickly while staying juicy inside and crunchy outside.

Can I use another nut instead of almonds in the romesco?

You sure can. Hazelnuts or walnuts work great, or use sunflower seeds if you need a nut-free option. Each gives the sauce a unique twist that still works beautifully with the Crunchy Chicken Romesco Sandwich.

What if I don’t have a food processor for the sauce?

No worries! You can finely chop the ingredients by hand and then mash together with a fork or mortar and pestle for extra rustic charm in your Crunchy Chicken Romesco Sandwich.
