Teriyaki Chicken Sandwich (照焼チキンサンド)

Chicken Teriyaki is one of those rare Japanese dishes that’s as popular in Japan as it is in the West. Although the traditional way of having it is to serve it with rice, Teriyaki Chicken is also enjoyed in more modern ways such as on pizza or in sandwiches.

Teriyaki Chicken Sandwich (照焼チキンサンド – Teriyaki Chicken Sando) has become such a popular variation on the classic that it’s sold in almost every convenience store, as well as many bakeries around Japan. The main difference with Western versions of this sandwich is that a Japanese Teriyaki Chicken Sandwich almost always includes an egg. This usually means egg salad at convenience stores, but you may find a quivering over-easy egg atop the chicken in bakeries or restaurants.

Why This Recipe Works?

Dusting the chicken with a light coating of starch helps the sauce adhere to the surface of the chicken, ensuring it is well seasoned.
Leaving the skin on allows it to protect and baste the meat, so it does not get tough. Most of the fat renders out of the skin, which changes its texture and helps the skin absorb the teriyaki sauce like a sponge.
An over-easy egg, made in the same pan as the chicken, adds richness and protein to the sandwich.

Ingredients for Teriyaki Chicken Sandwich

Chicken – I recommend using skin-on boneless chicken thighs for this. The skin keeps the chicken moist and tender, and since most of the fat renders out of it, its texture goes from rubbery to crispy. As the teriyaki sauce soaks into the skin, it loses its crispness, transforming the skin into a blanket of flavor. Breast meat will work as well, but it will not be as flavorful or juicy. If you’re using breast meat, I recommend butterflying it (cutting it in half horizontally to make it thinner), so it cooks through more evenly.
Potato Starch – The starch coating helps the sauce stick to the chicken. Potato starch has a better texture and doesn’t get gummy like cornstarch, which is why I prefer using it.
Teriyaki Sauce – Traditional Japanese teriyaki sauce is made with just three ingredients: soy sauce, sugar, and sake (or sometimes mirin). I used Kikkoman soy sauce, but any Japanese-style dark soy sauce will work. For the sugar, I used evaporated cane sugar, which I prefer because it has more flavor, but whatever you have on hand will work. As for the sake, the alcohol burns off while cooking, and it is added for its natural umami and aroma. You can substitute a pinch of MSG for the umami, but there is no good substitute for the fragrance. If you’re thinking about using Mirin instead of sake, check the ingredient label before buying it. Most “mirin” sold outside of Japan is a mixture of corn syrup, alcohol, and flavor enhancers and is not real mirin. This is why I recommend using sake over mirin.
Egg – This is optional, but as we know from Oyakodon, chicken and egg go great together, and the creamy yolk from an over-easy egg takes this teriyaki chicken sandwich to the next level.
Bread – Because the chicken is quite substantial, I usually make this sandwich using a bun. It will also work in a small crusty loaf of bread such as a batard (though you’ll need both pieces of chicken for 1 sandwich). I don’t recommend using sandwich bread because it will get soggy and fall apart due to the juicy ingredients inside.
Lettuce – The lettuce is mostly here for texture and color, which is why I like using a very crisp variety of lettuce such as Iceberg.
Tomato – Tomato adds sweetness and acidity to the sandwich, so be sure to use the ripest tomato you can find.
Mayonnaise – I prefer Japanese-style mayonnaise such as Kewpie because it’s tangier and has a closer flavor to homemade mayo.

How to Make Teriyaki Chicken Sandwich

To ensure the lettuce is as crisp as possible, soak a few lettuce leaves in a bowl of cold water.

For the chicken, use a tea strainer to dust a thin layer of starch onto both sides. Pat the thighs together to spread the starch evenly, dust off any excess, and then lay the chicken skin-side down in a cold non-stick frying pan (or cast-iron skillet).

Put the pan over low heat and let the fat in the skin slowly render out. This gently cooks the chicken while basting it, which keeps the chicken plump and juicy. It also gets rid of the rubbery texture of the skin while transforming it into a sponge that will soak up the flavors of the teriyaki sauce.

After about ten minutes, the skin should be crisp, and the chicken should be cooked about halfway up the sides. Flip the chicken over and turn up the heat to medium. Pan-fry the chicken, flipping it over every minute until it registers 160 degrees F (71C) on an instant-read thermometer (another 5-6 minutes). Carryover cooking will continue to raise the temperature, and the chicken will be cooked some more in the sauce, so you don’t need to get it up to 165F. Transfer the chicken to a plate.

Break the eggs into opposite sides of the pan and fold any stray flaps of egg over towards the center to give the eggs a shape that will fit neatly in your bun. When the egg whites are mostly cooked through, flip the egg over and fry the second side until the yolk reaches your desired doneness. I like my yolks runny, so I only give it a few seconds on the second side. I don’t recommend preparing eggs sunny side up for sandwiches because the fragile yolk will rupture prematurely when covered with a bun.

Transfer the eggs to a plate and use paper towels to wipe out all of the oil from the pan. This is important because the oil will make the teriyaki sauce greasy and cloudy.

Add the sugar, soy sauce, and sake to the clean pan, and allow the mixture to boil until it has thickened to the consistency of maple syrup. As the teriyaki sauce thickens, the bubbles will get large and glossy, which is a good sign it’s ready for the chicken to go back in.

Add the chicken back into the pan and flip it over continuously until the starch coating has absorbed the teriyaki sauce and it’s formed a thick glossy glaze.

To build the sandwich, spread a tablespoon of mayo on the bottom buns. Layer on a few slices of tomato, and then dry the lettuce and tear it to fit. Top the vegetables with the chicken and fried egg, and then finish your teriyaki chicken sandwich off with the top bun.

FAQ

What goes into a Teriyaki Chicken Sandwich?

The beauty of sandwiches is that they’re easy to customize, and you can add anything you like. That being said, in Japan, a teriyaki chicken sandwich typically contains chicken teriyaki as well as egg. The egg can be in the form of egg salad, boiled egg, or an over-easy egg. I also like to add lettuce and tomatoes to my sandwich for a little more variety in color, texture, and taste.

Can I use a different protein for this teriyaki sandwich?
