Key Ingredients & Substitutions

Chicken: Boneless, skinless chicken breasts are ideal for this recipe. If needed, you can substitute with chicken thighs, which offer a slightly richer flavor. They will also stay juicier.

Buttermilk: This is great for marinating, as it tenderizes the chicken. If you don’t have buttermilk, mix regular milk with a tablespoon of vinegar or lemon juice, letting it sit for a few minutes to sour.

Panko Breadcrumbs: They give the chicken a nice crunch. If you can’t find panko, regular breadcrumbs can work, but the texture may not be as light and crisp. Just consider adding some additional spices for flavor!

Romesco Sauce: Roasted red peppers really shine in this sauce. You could use jarred peppers for convenience. If you prefer a milder flavor, consider using roasted yellow peppers instead. Almonds can be swapped with walnuts or even sunflower seeds for a nut-free option.

Arugula: It adds a peppery kick! If arugula isn’t your thing, baby spinach works well too. For a different flavor, consider using baby kale.

How Do I Ensure My Chicken is Crispy?

Achieving that crunchy outer layer is all about the breading technique and frying method. Here’s how to get it just right:

  • Make sure your chicken is well-marinated in buttermilk. The buttermilk not only adds flavor but also helps the breading stick.
  • Always double-dip! After dipping the chicken in flour, back to the buttermilk and finally coat it in panko breadcrumbs. This creates a thicker and more textured coating.
  • When frying, maintain the oil temperature. Too low, and the chicken will absorb oil; too high, and the outside will burn before the inside cooks. Aim for medium-high heat.
  • Fry in batches if you can. If too much chicken is added at once, the temperature will drop and the chicken won’t crisp up properly.
  • Let the fried chicken drain on paper towels. This absorbs excess oil, keeping your chicken crunchy.

With these tips, you’ll be enjoying a perfectly crispy chicken sandwich in no time!

Ingredients You’ll Need:

For the Chicken:

  • 2 boneless, skinless chicken breasts
  • 1 cup buttermilk
  • 1 tsp paprika
  • 1 tsp garlic powder
  • Salt and pepper, to taste
  • 1 cup panko breadcrumbs
  • 1/2 cup all-purpose flour
  • Vegetable oil, for frying

For the Romesco Sauce:

  • 2 roasted red peppers (jarred or fresh)
  • 1/4 cup almonds, toasted
  • 1 clove garlic, minced
  • 1 tbsp sherry vinegar or red wine vinegar
  • 1/4 cup extra virgin olive oil
  • 1/2 tsp smoked paprika
  • Salt and pepper, to taste

For the Sandwich:

  • Ciabatta or rustic sandwich rolls, halved
  • Fresh arugula, about 1 cup

How Much Time Will You Need?

This delightful sandwich takes about 30 minutes to prepare and cook, along with a marinating time of at least 30 minutes (up to 2 hours if you have time). If you’re making the romesco sauce yourself, it adds a little extra prep but is definitely worth it for that fresh flavor!

Step-by-Step Instructions:

1. Preparing the Chicken:

Begin by slicing the chicken breasts horizontally to create thinner cutlets. This will help them cook evenly and be juicier. In a bowl, mix the buttermilk, paprika, garlic powder, salt, and pepper. Place the chicken pieces in the marinade, covering them well, and let them marinate for at least 30 minutes (if you can wait, marinate for up to 2 hours for even more flavor).

2. Making the Romesco Sauce:

While the chicken marinates, we can whip up the romesco sauce! In a blender or food processor, combine the roasted red peppers, toasted almonds, minced garlic, sherry vinegar, smoked paprika, and a bit of salt and pepper. Pulse this mixture until everything is chopped and mixed well, and then slowly drizzle the olive oil in while blending, until the sauce is smooth. Give it a taste and add more salt or pepper if needed!

3. Breading the Chicken:

Now it’s time to bread the chicken! Get two shallow bowls: one with seasoned flour (just add salt and pepper) and the other filled with panko breadcrumbs. Take one chicken piece out of the buttermilk, dredge it in the flour, then dip it back into the buttermilk briefly, and finally coat it thoroughly in the panko breadcrumbs. Make sure to press the breadcrumbs on so they stick well!

4. Cooking the Chicken:

In a large skillet, heat about 1/4 inch of vegetable oil over medium-high heat. Once hot, add the breadcrumb-coated chicken cutlets to the pan. Fry them for about 3-4 minutes on each side until they are golden brown and cooked through. Once done, place the chicken on paper towels to drain any excess oil.

5. Assembling the Sandwich:

Take the ciabatta or sandwich rolls and toast them lightly for some extra crunch! Generously spread romesco sauce on both the top and bottom halves of the bread. Place the crispy chicken cutlets on the bottom half, then add a layer of fresh arugula on top. Place the top half of the bread to close the sandwich and cut it in half.

6. Serve:

Serve your Crunchy Chicken Romesco Sandwich immediately while the chicken is still hot and crispy. This perfect blend of flavors and textures is sure to be a hit! Enjoy it with your favorite side, like chips or a salad!

This sandwich is all about the contrast of crunchy chicken, nutty and smoky romesco sauce, topped off with the freshness of peppery arugula in soft bread. Enjoy and delve into every delicious bite!

FAQ for Crunchy Chicken Romesco Sandwich

Can I Use Chicken Thighs Instead of Breasts?

Absolutely! Chicken thighs are a great alternative as they’re juicier and have more flavor. Just adjust the cooking time slightly, as thighs may take a bit longer to cook through compared to breast meat.

What Other Bread Can I Use?

While ciabatta is delicious, you can use any sturdy bread like baguette, focaccia, or even whole grain sandwich rolls. Just make sure it can hold the filling without getting soggy.

How Do I Store Leftover Sandwiches?

If you have leftovers, store them in an airtight container in the fridge for up to 2 days. To maintain the crispiness, it’s best to keep the components separate and assemble the sandwich just before eating. Reheat the chicken in the oven for best results.

Can I Make the Romesco Sauce Ahead of Time?

Yes, the romesco sauce can be made ahead of time! Store it in an airtight container in the fridge for up to a week. Just give it a good stir before using, as it may thicken in the fridge.
