Oil Temperature Tricks

Your oil needs to stay around 350°F to get chicken that's super crunchy outside but still juicy inside.

Prep-Ahead Options

You can mix up the lemon dressing three days early, and get your chicken breaded a few hours before cooking time.

Getting Perfect Crunch

After breading your chicken, let it sit for 10 minutes so the coating sticks better during frying.

What to Serve With It

This rich sandwich works great with something light on the side – try a simple green salad or some fresh cut fruit.

Mix It Up Ideas

Try swapping cheese types or adding some slow-cooked onions for more flavor depth.

Keeping Leftovers Fresh

While it's best eaten right away, you can keep all parts separate and put together a fresh sandwich tomorrow.

My family always adds a thin layer of whole grain mustard on the bottom half. This little trick brings in just the right amount of tang that works with all the other flavors.

I've made this sandwich countless times, tweaking little things along the way. What I've learned is that success comes down to small details – oil temp, timing, and assembly order all matter. When the cool lemon dressing meets the spicy-sweet honey while that salty Parmesan crust adds crunch, you'll get something truly special. It doesn't matter if it's for a fancy lunch or just Tuesday dinner – this sandwich shows that simple foods done right can be the most memorable ones you'll ever make.

Frequently Asked Questions

→ Can I prep parts of this ahead?
Definitely! Whip up the lemony dressing two days in advance and bread the chicken a few hours before frying. Just save the lettuce dressing until you’re ready to serve.
→ How do I get super crispy chicken?
Be sure the oil is hot before frying and keep pieces spaced apart. Press the panko firmly into the chicken so it clings better.
→ Will regular bread work instead of croissants?
It’s an option, but croissants bring the buttery flavor and flaky texture that make this sandwich amazing. Toasting them with Parmesan amps up the crunch.
→ Is the hot honey really needed?
Not a must, but it’s a game changer! The sweetness with a bit of spice really balances the creamy and savory elements.
→ How can I stop the avocado from turning brown?
Cut the avocado right before putting sandwiches together. The lemon in the dressing also helps slow browning.

Ingredients

→ Chicken Coating

01 1 cup panko bread crumbs
02 3 large eggs, beaten
03 2 chicken breasts, boneless and skinless, halved and flattened (about 1½ lbs total)
04 ¼ cup grated Parmesan, freshly shredded
05 1 teaspoon garlic seasoning powder
06 ½ cup plain flour
07 A dash of kosher salt and black pepper

→ Lemon Sauce

08 2 tbsp freshly squeezed lemon juice
09 ½ cup Greek yogurt, plain
10 1 clove garlic, finely chopped
11 A teaspoon of smooth Dijon mustard
12 A teaspoon of honey for sweetness
13 Season with kosher salt and black pepper as preferred

→ Sandwich Build

14 4 large croissants, cut in half
15 ¾ cup of grated Parmesan
16 2 ripe, sliced avocados
17 4 cups of Romaine lettuce, chopped
18 2 tbsp butter, melted
19 Optional: some hot honey for drizzling

Instructions

Step 01

Slice the chicken breasts into halves and pound them flat. Then, get three separate dishes ready: one with flour and spices, another holding the eggs, and the last with Parmesan and panko crumbs mixed together.

Step 02

Dip each chicken piece first into the flour so it’s covered, next into the eggs, and finally press it into the panko-Parmesan mix to coat well.

Step 03

In a big, heavy pan over medium-high heat, warm some oil. Fry the chicken for about 2-3 minutes on each side until it's crispy, golden, and done inside. Set on paper towels.

Step 04

In a small bowl, combine the yogurt, lemon juice, mustard, honey, minced garlic, salt, and pepper. Stir until everything comes together and is smooth.

Step 05

Take your croissants, split them open, brush with butter, and sprinkle Parmesan on top. Broil for 1-2 minutes until lightly browned and cheesy.

Step 06

Mix the Romaine lettuce with the leftover Parmesan and pour the dressing on top. Toss until evenly coated.

Step 07

Start with the bottoms of your croissants, layer the chicken first, then drizzle some hot honey if you’d like, followed by the avocado slices and dressed lettuce. Finish with the cheesy croissant tops and serve them right away while warm.

Notes

  1. Trim the chicken so it fits inside the sandwich - it’s fine if edges stick out a bit.
  2. Keep an eye on those croissants under the broiler. They can burn fast!
