One thing I love about cooking with seasonal, fresh produce is that it often yields a delicious meal, even when I’m cooking without a plan. This summer inspired crispy chicken sandwich recipe is one of those beautiful, unexpected results.

Fresh bell peppers, a quick avocado spread with cilantro and lime, and seasoned buttermilk crispy chicken cutlets make a delicious sandwich that doesn’t take too long to cook, even from scratch. We make it with homemade burger buns, and serve it alongside a cool scoop of corn avocado salad or potato and egg salad and sit on the patio, enjoying that warm summer weather with every bite.

Ingredients & Substitutions

The ingredients you’ll need to make these sandwiches are fresh and delicious in the summer months, but they’re also available at most grocery stores throughout the year.

Ingredients for making buttermilk crispy chicken sandwiches including bell peppers, avocado, chicken breast, buns, and seasoning.
  • Boneless, skinless chicken breast – You’ll need about 1 lb of chicken breast. This happened to be one HUGE one for me, but use whatever adds up to that amount.
  • Flour – I’ve used both all purpose flour and brown rice flour (to make it gluten free), both are great!
  • Seasonings – Salt, pepper, onion powder, garlic powder, and cayenne
  • Buttermilk – Either store-bought, or mix 1 tablespoon of vinegar or lemon per 1 cup of milk to make it homemade.
  • Oil – I prefer a neutral flavor, like grapeseed, canola, or vegetable oil.
  • Red or Orange Bell Peppers – Choose sweet red or orange peppers, make sure they’re plump and firm.
  • Onion – Either yellow or sweet onions.
  • Avocado – I used two small California Avocados, you can also use one large Hass avocado or whatever your market has.
  • Cilantro – I’ve also used parsley. It’s less intense than cilantro, but it does add an herbaceous freshness I recommend.
  • Lime Juice – Fresh or bottled will both work just fine.
  • Bread – I prefer my homemade hamburger buns, but you can use a sturdy roll, toasted bread, or any other you like.

For the Love of Bell Peppers

Step by Step Instructions

There are a couple of steps to making these, but none are complicated or stressful. You’ll need two skillets, one with high enough sides to pan fry the chicken.

Step 1 – Prep the Chicken and Produce

Slice the chicken into thin cutlets. You can do this with a knife or by pounding it thin and slicing it from there. Add the cutlets to a bowl with 2 cups of buttermilk and make sure everything is coated.

Next prep the remaining ingredients. Peel and slice the peppers and onions, dice the avocado, chop the cilantro, and season your flour.

Step 2 – Mash the avocado and season the flour

Get your pans heating on the stove over medium heat. Add the lime juice and salt to the avocado and mash into a creamy spread. Pop that in the fridge while you finish cooking.

Add 1 tablespoon of oil to your pan for the peppers and onions. When the oil is shining, add the peppers and onions and stir occasionally to let them get tender, about 10-15 minutes, while you turn your attention to the chicken.

Step 3 – Bread and Fry the Chicken

Add a 1/2 cup of oil to the second pan for the chicken. Let it get hot (which should be fast if your pan was preheated), then start breading and frying the chicken.

Take one cutlet at a time from the buttermilk. Let the excess drip off, but don’t wipe it away. Press into the flour until the cutlet is well floured, and gently shake off the excess. Place the cutlet in the hot oil to fry for 3-5 minutes per side, or until they’re cooked through to 165°F with a thermometer. Set them a cooling rack to allow airflow and prevent the chicken from going soggy while you finish cooking

Step 4 – Assemble

We like to have a layer of avocado on the bottom bun with 1-2 pieces of chicken on top, finished with a scoop of tender peppers and onions. Feel free to add a chipotle lime sauce, red pepper aioli, or jalapeno mayo to the top bun for added flavor.

FAQs

Can I make a crispy buttermilk chicken sandwich with different toppings?

Of course! This can be adjusted seasonally by adding a cabbage and carrot slaw in the fall and winter, or enjoy it simply with tomatoes, cheese, and lettuce like a true classic.

Can I make this gluten free?

I’m no gluten free expert, but I have used brown rice flour with this and LOVED the crispiness I got on the chicken. Make sure to use gluten free buns as well.

Can I make this without buttermilk?

Yes, you can skip the buttermilk soak and simply dip the chicken cutlets in well-whisked eggs before the flour. For gluten free rice flour, you can just use water!

Can I use different cuts of chicken?

Sure, chicken cutlets, tenders, or boneless skinless thighs will all work. Just keep them thin or the cooking time will increase.

All that’s left is to eat and enjoy! I love how simply these came together, they’re like a version of fried chicken sandwiches with a bit of California flair, fresh avocado spread, summer bell peppers and a crispy fried chicken. They’re satisfying and fantastic to serve for a family dinner, especially with oven roasted baby potatoes or homemade twice fried french fries.

    Oh gosh these burgers look amazing, and I love that you made the buns too – that’s something I usually skimp out on but not anymore! Also, brown rice flour – super keen to experiment with this. If the chicken turns out half as crispy as it looks in your pics I will be one very happy foodie. 😀

    1. Thanks Laura for your awesome comment! Those buns really are amazing, and I hope you enjoy the sandwich. I find the rice flour really simple but effective in coating the chicken, but I’d love to hear it goes for you!
