Fried Chicken Sandwich Ingredients For the Chicken Chicken Thighs – Bone-in, skinless chicken thighs provide maximum juiciness; swap for chicken breasts if you prefer leaner meat. Buttermilk – This ingredient acts as a tenderizer and helps the crispy coating adhere; substitute with yogurt or milk mixed with vinegar for a similar effect. Hot Sauce – Adds the perfect spice to the marinade; choose your favorite brand and adjust quantity based on your heat preference. Garlic Powder – A handy flavor booster; fresh garlic can replace it, but might change the texture slightly. Onion Powder – Complements the garlic beautifully; feel free to omit if you don’t have any on hand. Paprika – Enhances color and adds a mild flavor; try smoked paprika for a deeper taste. Sugar – Balances the flavors beautifully in the marinade; honey or maple syrup can work as substitutes. Fine Sea Salt & Ground Black Pepper – Essential for seasoning; adjust these to suit your taste. For the Coating Potato Starch – Creates an outstandingly light and crisp coating; you can also use cornstarch or all-purpose flour if needed. For the Spicy Aioli Mayonnaise – Forms the creamy base for the aioli; opting for homemade will enhance freshness! Garlic Cloves – Intensify the garlic flavor; consider black garlic for added sweetness. Balsamic Glaze or Vinegar – Provides the right acidity for the aioli; vinegar acts as a suitable alternative. Whole Grain Mustard – Adds tang and depth; substitute with Dijon mustard if it’s what you have. For Assembling Brioche Burger Buns – Wonderfully buttery and soft, ensuring the best sandwich experience; go for gluten-free buns or lettuce leaves for a low-carb option. Pickles – Add a delightful crunch and touch of acidity; spicy pickles can elevate the flavor profile! Optional Vegetables – Lettuce, tomatoes, or cheese to personalize your delicious fried chicken sandwich further. Dive into this vibrant, crispy fried chicken sandwich adventure, and savor how simple ingredients can transform into something remarkably delicious! Enjoy your cooking! Step‑by‑Step Instructions for Buttermilk Marinated Crispy Fried Chicken Sandwich Step 1: Marinate Chicken In a ziplock bag, combine your chicken thighs with buttermilk, hot sauce, garlic powder, onion powder, paprika, sugar, salt, and pepper. Seal the bag and gently massage the marinade into the chicken. Refrigerate overnight to ensure deep flavor penetration and optimal tenderness, allowing the buttermilk magic to work wonders for your fried chicken sandwich. Step 2: Prepare Dredging Station Remove the marinated chicken from the fridge and set up your dredging station. Place a generous amount of potato starch on a large plate, ensuring it’s spread evenly. Separate the leftover marinade into a bowl, as you’ll use it to coat the chicken just before frying. This will create that perfect crispiness for your fried chicken sandwich. Step 3: Coat Chicken Dip each marinated chicken thigh into the reserved marinade, letting any excess drip off. Next, dredge the chicken in the potato starch, ensuring it’s thoroughly coated—aim for a rough surface as this will enhance the crunch when fried. This step is crucial for achieving the crispiness that makes the buttermilk marinated crispy fried chicken sandwich so irresistible. Step 4: Heat Oil In a deep, heavy pot or a deep fryer, heat your frying oil to 375°F (190°C). Use enough oil to fully submerge the chicken thighs. To test if the oil is ready, drop a small pinch of potato starch into the oil; if it sizzles immediately, you’re good to go! This temperature will ensure a crispy, golden exterior for your fried chicken sandwich. Step 5: Fry Chicken Carefully lower the coated chicken thighs into the hot oil, frying in batches if necessary to avoid overcrowding. Fry for about 3-4 minutes per side or until they turn a beautiful golden brown. The internal temperature should reach 165°F (75°C), ensuring your buttermilk marinated crispy fried chicken is cooked through and juicy. Step 6: Drain Chicken Once cooked, remove the fried chicken from the oil using a slotted spoon and carefully place it on a wire rack. This allows excess oil to drain off while helping maintain that crispy texture. If you want to keep them warm, place the rack in a low-temperature oven while you finish frying the rest. Step 7: Make Aioli In a small bowl, combine mayonnaise, garlic cloves, balsamic glaze, and whole grain mustard. Using an immersion blender or food processor, blend until smooth and creamy. Adjust seasoning to your taste, and refrigerate until ready to use. This spicy aioli will add a delightful kick to your fried chicken sandwich. Step 8: Assemble Sandwich Toast your brioche buns until golden brown for a perfect finishing touch. Spread a layer of the homemade spicy aioli on both sides of the bun. Layer in the crispy fried chicken, followed by pickles and any optional toppings like lettuce or tomatoes. Your Buttermilk Marinated Crispy Fried Chicken Sandwich is now ready to be devoured! Fried Chicken Sandwich Variations Feel free to get creative and make this fried chicken sandwich uniquely yours with these simple twists! Gluten-Free: Substitute the brioche buns with gluten-free buns or wrap in lettuce leaves for a low-carb delight. Enjoy the same crispy goodness without the gluten! Spicy Kick: Add sliced jalapeños or a swirl of sriracha to your spicy aioli for extra heat. This zesty addition will ignite your taste buds, making each bite a flavorful adventure. BBQ Flavor: Swap out the spicy aioli for your favorite BBQ sauce to create a smoky twist. Slathering BBQ sauce not only adds sweetness but perfectly balances the crunch of the chicken. Herbaceous Touch: Mix fresh herbs like dill or parsley into the aioli for a fresh flavor boost. This bright note will elevate the whole sandwich, making it feel gourmet. Cheesy Goodness: Melt cheddar or pepper jack cheese on the chicken right after it comes out of the fryer for a gooey delight. The melty cheese adds richness that complements the crispy exterior beautifully. Asian Infusion: Top the sandwich with pickled vegetables and a drizzle of sesame oil for an Asian-inspired twist. This vibrant combination gives your sandwich an exciting flavor profile reminiscent of summer rolls. Keto-Friendly: Use almond flour instead of potato starch for the crispy coating and serve the chicken on a bed of greens. This low-carb option still delivers on crunch and flavor without the carbs.

Expert Tips for the Best Fried Chicken Sandwich Perfect Marinade Time: Marinate the chicken overnight for maximum flavor and tenderness. Don’t rush this step, as the buttermilk works magic! Dredging Don’ts: Avoid over-coating your chicken with starch. Aim for a rough texture rather than a thick layer, which helps achieve that delightful crispiness. Oil Temperature: Always check the oil temperature before frying. Using too cool oil results in greasy chicken; too hot can burn the coating. Drain Properly: Allow your chicken to rest on a wire rack after frying, not on paper towels, to keep the exterior crispy and airy. Play with Spices: Don’t hesitate to customize your spicy aioli! Add extra spices or herbs to match your flavor preference, enhancing your fried chicken sandwich experience. Leftover Love: Store any leftover chicken in an airtight container and reheat in the oven for the best texture later. Enjoy that crispy goodness again!

Buttermilk Marinated Crispy Fried Chicken Sandwich Recipe FAQs How should I select my chicken thighs? Absolutely! When choosing chicken thighs, look for bone-in, skinless options as they provide the juiciest results. Aim for thighs that are plump and free of any dark spots or discoloration. If you prefer a leaner option, you can swap them out for chicken breasts, though this may slightly alter the texture and flavor. What’s the best way to store leftover fried chicken? Very! Leftover fried chicken can be stored in an airtight container in the refrigerator for up to 3 days. This helps to keep it fresh and delicious.

If your chicken isn’t coming out crispy, check a few things. Ensure that your oil is hot enough (375°F or 190°C) before frying, as too cool oil can lead to a greasy texture.
