Korean Isaac Toast Recipe! (Isaac Korean Street Toast Recipe)
I have shared a Korean street toast recipe a while ago, that’s more of street vendor style. Today, I wanted to share a copycat recipe of the most popular Korean street toast franchise restaurant, Isaac Toast.
Isaac Toast is known for their signature kiwi sauce in their toast and it’s been secret, still, nowadays!! Their kiwi sauce is creamy, sweet, savory, and just perfect for street toast!
I growing up eating this sandwich and still remember when Isaac Toast just opened, it was a mind-blowing flavor. Until then, Korean street toast’s sauce was just ketchup, mayo, and sugar. As my original Korean street toast recipe. I and my friends were addicted to Isaac Toast, we had to have it almost every day! 🤣
I’m very confident to say that I got the secret sauce almost identically the same as the original sauce. So the only way you to find out is just to give this recipe a try!
Are you ready? Let’s get started!
In a 2-cup measuring cup, add 1 peeled and chopped green kiwi, 1 small chunk of pineapple (pineapple is optional!), 1/8 of medium size onion, 4 tbsp mayonnaise (I highly recommend using Korean or Kewpie brand!), 3 tbsp honey and 1/2 tsp salt. Add black pepper to your taste. Blend all of the ingredients until smooth with a hand blender.
This sauce will be good enough for 8 to 10 sandwiches and last up to 7 days in a refrigerator. Set aside.
Beat egg with a pinch of salt and pepper with sweet corn. Set aside.
Slice green cabbage thinly as possible or prepare shredded cabbage. Also, slice sweet gherkins.
Sweet gherkins are also the signature flavor of Issac Toast, so don’t skip them!!
Butter your cooking surface. You can use a griddle, large skillet, or cast iron pan.
We are going to toast the bread first. While bread is toasting, cook sliced ham and egg in a square cooking mold if you have one.
You don’t have to use the mold, but it makes the square size egg that fits perfectly with bread, like real Isaac Toast!
This is the exact square mold I have and used for this recipe. It works great! Just make sure to grease the inside so the egg won’t stick to the surface of the mold. When I use this mold, I feel like I became the real Korean street food vendor! lol 🤣
Flip over bread, but before flipping, butter cooking surface once again. Spread about 1 tbsp kiwi sauce on each toast.
Remove cooking mold from egg and flip it over. Place cheese on top of the egg and place ham right on top. This way, the cheese will melt perfectly! Then gherkins and cabbage.
Finally, top it with another piece of toast. Of course, sauce side down. Serve immediately.

The sandwich looks very appetizing. How does the shredded cabbage get cooked inside the sandwich? Or is it eaten as raw cabbage? I appreciate an answer to my Inquiry!!!
It is eaten as raw cabbage for the crunchy element, it is SO delicious!
Yesterday, I made this recipe and all I can say the taste was phenomenal! I made 9 sandwiches as some member of my family had two sandwiches. Everything was perfect but my sauce was more runny than one shown in your video. The taste was great though!
Any idea what I can do to make the sauce a little thicker so it does run off the edge of the bread? I had extra sauce in a bowl and my boys dipped the sandwich in the bowl. I wish you were here to see the mess!!!
This recipe is a keeper for me. Thank you.
So I would recommend putting the sauce in the refrigerator for a couple hours or just make it ahead of time to put in the fridge. This will definitely make the sauce thicker.
Just made this for my bf and I for lunch. He said it was killer and I agree!
So glad I could help!
One of the best snacks/ Comfort food, the sauce is amazing!
Yay! So glad I could help!
This is now a food staple in our family, the taste is unreal!!
I also tried a version with a fried egg with runny yolk instead of scrambled. It was even more delicious as the yolk creeped into the cabbage and made everything really creamy!
what a great idea!
Will it throw the ratios off if you use two eggs per sandwich?
No that should be fine!
Annyeonghaseyo Ms. Seongyeong!
Just wanted to thank you for posting this recipe! The mister and i were so disappointed with a wannabe Japanese katsusando we had in Rotterdam a few weeks ago. But since we’ve been watching Jolly and Korean Englishman on YouTube and their gushing over Isaac Toast, i just had to try and make this!
Your recipe and that secret sauce totally saved the day! Scrumptious!
and now i need to find your book… 😉
