This Creamy Cheesy Tuna Bun is an easy savory snack for anytime of the day. It's like a cheesy tuna melt - but in an Asian bun style! Made with a base of my mom's famous Asian Milk Bread, this Cheesy Tuna Bun tastes just like the Asian bakeries. With a simple topping of corn, tuna, mayo, and cheese, this tuna bun is cheesy, savory, and sweet.
Mix two tablespoons of flour and ½ cup of water. Once combined, bring it to a simmer.
Simmer on medium heat for 3-4 minutes or until it thickens and becomes a roux.
Remove from heat and store in an air-tight container in the fridge for 2 hours or until it has thoroughly cooled down. You can prepare the step the night before to save time.
Milk Bread:
Add flour, sugar, salt, yeast, egg, milk, chilled tangzhong, and water in a stand mixer. Mix until thoroughly combined; this will take around 10 minutes; the dough may seem sticky at first, but keep mixing until it is thoroughly combined.
Next, add in room temperature butter, turn on the stand mixer, and mix for another 10-15 minutes or until combined. You can check if the dough is ready by stretching the dough; it should be elastic and see-through. Refer to Youtube Video to get a sample of how to test the dough.
Once the dough is smooth and no longer sticky, form it into a ball, cover it with a damp towel, and let it rest for 1 hour or until it doubles in size.
Final Steps:
Punch out the air bubble and cut the dough into eight even pieces; cover with a damp towel to prevent the dough from drying out.
Take one piece of the dough, and flatten it with your hand. Roll out the dough with a rolling pin, pushing out all the bubbles. Roll the dough to an oval shape, around 5 inches lengthwise.
Next, Roll the dough down from the top, making sure there are no air bubbles, and pinch the opening close.
Using a scissor cut the dough slightly open in the middle; you want to cut the dough to around ⅓ of the way deep.
Cover with a damp towel, and rest the buns rest for 30 minutes.
In the meantime, prepare the creamy tuna mixture by mixing tuna, corn, mayo, and season with black pepper.
After 30 minutes, sprinkle on cheese, layer with creamy tuna mixture, and top with more cheese.
