Elevate instant ramen into a rich Tonkotsu-style bowl. Mayonnaise, egg yolk, and the seasoning packet create a surprisingly creamy, decadent broth in minutes.
This viral internet hack has revolutionized how people enjoy late-night instant noodles. By emulsifying an egg yolk and mayonnaise with the standard seasoning packet, you can mimic the rich, fatty mouthfeel of a long-simmered pork bone broth. It is a quick and satisfying way to upgrade a simple pantry staple into a comforting, restaurant-inspired bowl.
Ingredients
- 1 pack instant noodles with seasoning powder
- 1 tbsp kewpie mayonnaise
- 1 egg, separated
- 1 hot dog sausage, sliced
- 2 slices kamaboko fish cake
- 2 crab sticks, shredded
- to taste fresh cilantro
Instructions
- 1Add the seasoning powder

Empty the instant noodle seasoning powder packet into a clean, dry serving bowl. This forms the flavorful base of our rich Tonkotsu-style broth hack.
Tip: Only use the powder packet for now. Save any oil or dried vegetable packets for later steps if your noodle brand includes them. - 2Add mayonnaise

Squeeze a generous dollop of mayonnaise directly into the bowl with the seasoning powder. The mayonnaise adds creaminess and mimics the rich, fatty mouthfeel of a traditional long-simmered Tonkotsu broth.
Tip: Use a rich, egg-yolk-based mayonnaise (like Japanese Kewpie mayo) for the best flavor and authentic creamy texture. - 3Add an egg yolk

Crack an egg, separate the yolk from the white, and carefully drop the raw egg yolk into the bowl alongside the mayonnaise and seasoning. The yolk will act as an emulsifier to bind the sauce together and enrich the broth.
Tip: Make sure the bowl is at room temperature and the hot water hasnt been added yet so the egg yolk doesnt scramble. - 4Mix the broth base

Using chopsticks, vigorously stir the seasoning powder, mayonnaise, and egg yolk together until they form a smooth, thick, and homogenous paste. Ensure there are no dry lumps of powder left in the mixture.
Tip: Take your time mixing this thoroughly; a well-mixed base guarantees a silky smooth broth without any unappetizing clumps. - 5Boil the noodles

Bring a pot of water to a rolling boil over medium-high heat. Carefully place the instant noodle cake into the boiling water and let it cook undisturbed for a minute until it begins to soften and separate.
Tip: Do not overcook the noodles at this stage, as they will continue to soften slightly once they are combined with the hot broth later. - 6Add sausages and fish cakes

While the noodles are boiling, add your desired toppings into the same pot to heat them through. Toss in sliced sausages and fish cakes to cook alongside the noodles and infuse the noodle water with extra flavor.
Tip: You can customize this step with any quick-cooking ingredients you have on hand, like thinly sliced mushrooms or leafy greens. - 7Scoop broth into the sauce mixture

Scoop a ladleful of hot broth directly from the cooking pot and pour it into the bowl containing the prepared sauce mixture, blending it smoothly.
Tip: Add the hot broth gradually to temper the sauce and prevent any clumping. - 8Pour the mixed sauce back into the pot

Pour the thoroughly mixed sauce from the bowl back into the boiling pot of noodles to enrich the broths flavor.
Tip: Stir the noodle soup continuously while pouring to ensure an even distribution of the sauce. - 9Pour in the remaining egg white

Pour the remaining egg white in a thin stream directly into the bubbling pot of noodles to create delicate egg ribbons.
Tip: Let the egg settle briefly before stirring to maintain nice texture and ribbons. - 10Add shredded crab sticks

Scatter the shredded crab sticks evenly across the top of the cooking noodles and broth.
Tip: Do not over-stir after adding the crab sticks so they keep their distinct shredded appearance. - 11Garnish with fresh cilantro

Finish the dish by adding a generous handful of fresh cilantro on top of the simmering pot as an aromatic garnish.
Tip: Add cilantro right before turning off the heat to preserve its vibrant green color and fresh flavor.
