Step‑by‑Step Instructions for Crunchy Chicken Romesco Sandwich
Step 1: Prepare the Chicken Cutlets
Begin by slicing the chicken breasts horizontally to create four thin cutlets. Set up a breading station with three bowls: one filled with flour, another with beaten eggs, and the last with panko breadcrumbs. Dip each chicken cutlet in flour, shake off the excess, then coat it in egg, followed by the panko, ensuring an even coverage.
Step 2: Fry the Chicken
Heat a generous drizzle of olive oil in a large skillet over medium heat until shimmering, about 2 minutes. Carefully add the breaded chicken cutlets to the pan, ensuring not to overcrowd them. Fry each cutlet for about 4 minutes per side, cooking until they are golden brown and crispy. Once cooked, transfer them to paper towels to drain excess oil.
Step 3: Make the Romesco Sauce
While the chicken is frying, gather the romesco sauce ingredients. In a blender or food processor, combine garlic, jarred roasted red bell peppers, sun-dried tomatoes, almonds, balsamic vinegar, olive oil, paprika, and kosher salt. Blend until smooth, adjusting the oil for desired consistency. The romesco sauce should have a rich, vibrant color and a creamy texture.
Step 4: Prepare the Salad Mixture
In a mixing bowl, combine sour cream, mayonnaise, freshly squeezed lemon juice, grated Parmesan cheese, and a generous pinch of black pepper. Fold in chopped gem lettuce and arugula, ensuring the greens are well-coated in the creamy mix. This salad adds a refreshing crunch to your Crunchy Chicken Romesco Sandwich.
Step 5: Make Garlic Parsley Butter
To enhance the sandwich, prepare the garlic parsley butter. In a small bowl, mix softened butter with minced garlic and finely chopped parsley until well combined. Take your focaccia bread and slice it in half horizontally. Spread the garlic butter mixture evenly over both cut sides, topping with additional grated Parmesan for extra flavor.
Step 6: Grill the Focaccia
Preheat a grill or a grill pan over medium heat. Place the prepared focaccia, buttered side down, on the grill. Cook for about 3–4 minutes, or until the bread is bubbling and lightly golden. Keep an eye on it to prevent burning and achieve that desirable crispiness.
Step 7: Assemble the Sandwich
Now it’s time to create your delicious Crunchy Chicken Romesco Sandwich! On the grilled focaccia halves, spread a generous layer of romesco sauce. Layer the crispy chicken cutlets on top, followed by a hearty spoonful of the zesty salad mixture. Close the sandwich with the other half of focaccia, and press gently.
Step 8: Serve and Enjoy
Finally, carefully wrap each sandwich in parchment paper to keep everything together. Serve immediately for the best crunch, or store in the fridge for later enjoyment. This delightful Crunchy Chicken Romesco Sandwich is perfect for summer picnics or a satisfying meal at home!

To enjoy, just reheat the chicken in a skillet until warm, then assemble your sandwich with the grilled focaccia, zesty salad, and romesco sauce for a delightful meal that’s just as delicious, saving you precious time during busy weeknights.
Expert Tips for Crunchy Chicken Romesco Sandwich

-
Rest Chicken: Let the fried chicken rest on paper towels before assembling the sandwich to absorb excess oil and keep it crunchy.

Crunchy Chicken Romesco Sandwich Recipe FAQs
How do I choose ripe ingredients for my Crunchy Chicken Romesco Sandwich?
Absolutely! For the best flavors, choose the freshest ingredients. Look for vibrant jarred roasted red bell peppers that are plump and glossy, ensuring they are flavorful and sweet. When selecting sun-dried tomatoes, opt for those that are moist rather than overly dry, as they will blend smoothly into the sauce. Fresh herbs should appear bright and fragrant, while your chicken breast should be fresh with no dark spots or unpleasant odors.
How should I store my Crunchy Chicken Romesco Sandwich?
The more the merrier! Wrap the assembled sandwiches tightly in parchment paper and place them in an airtight container. They can be stored in the fridge for up to 2 days. Keep in mind, they are best enjoyed fresh, as the bread will lose its crunch over time.

Can I freeze the Crunchy Chicken Romesco Sandwich?
Very! To freeze, separate the components: freeze the chicken cutlets and romesco sauce in airtight containers for up to 3 months. Thaw them overnight in the fridge before reheating the chicken in an oven at 375°F (190°C) for about 10 minutes to regain its crisp texture. Assemble your sandwich fresh after reheating for the best result!
What should I do if the chicken is not crispy enough?
Don’t worry, it happens to the best of us! If your chicken doesn’t turn out as crispy as you hoped, first ensure your oil was adequately heated (around 350°F/175°C) before frying. Avoid overcrowding the pan, which can trap steam and soften the breading. If thick breading is the result, let the cutlets rest on paper towels after frying to absorb excess moisture for better crunch.
Are there any dietary considerations for the Crunchy Chicken Romesco Sandwich?
Of course! If you or someone you’re serving has egg allergies, you can easily substitute the egg with olive oil for a vegan-friendly option. Additionally, the recipe is already adaptable for gluten-free diets by using gluten-free flour and breadcrumbs. Check any store-bought sauces (like the mayonnaise and romesco) to ensure they align with your or your guests’ dietary needs.
Can I use other nuts instead of almonds in the romesco sauce?
Absolutely! In case of nut allergies or preferences, feel free to substitute almonds with walnuts or cashews for a similar texture and nutty flavor. Just remember, different nuts may slightly alter the flavor profile, enhancing the rich taste of your Crunchy Chicken Romesco Sandwich while keeping it deliciously unique!
