Japanese Chashu Abura Soba (Oil-Mixed Noodles)
Abura soba is a savory, brothless noodle dish featuring chewy noodles coated in a rich, flavorful oil-based sauce, topped with tender chashu pork and a raw egg yolk.
Abura soba, literally translating to oil noodles, is a beloved Japanese street food that highlights the pure texture of wheat noodles. Unlike traditional ramen, this dish relies on a concentrated base sauce rather than a soup, which clings to every strand to create an intense, umami-packed eating experience. The addition of a raw egg yolk creates a creamy emulsion when stirred, perfectly balancing the savory chashu and crisp garnishes.
Ingredients
- 200 g ramen noodles
- 100 g chashu pork slices
- 1 tbsp leftover chashu sauce
- 1 tsp cooking wine
- 1 tsp doubanjiang
- 1 egg yolk
- 1 soft-boiled egg
- 2 tbsp chopped green onions
- 30 g bamboo shoots
- 2 nori seaweed strips
- to taste sesame seeds
Instructions
- 1Prepare the sauce base

Add cooking wine and a spoonful of doubanjiang (spicy bean paste) into the pot with the leftover chashu sauce to build a rich flavor profile.
Tip: If you dont have leftover chashu sauce, you can create a base using oyster sauce, soy sauce, sesame oil, minced garlic, and sugar. - 2Simmer the glaze

Simmer the sauce mixture over medium heat until it reduces and thickens into a glossy, dark glaze suitable for coating noodles.
Tip: Watch the heat carefully; the sauce contains sugar and can burn quickly once it begins to thicken. - 3Pour the sauce

Pour a small amount of the prepared, thickened sauce into the bottom of a dark serving bowl to serve as the flavor base for the noodles.
Tip: Adjust the amount of sauce based on how much you intend to serve; this will be mixed directly with the noodles. - 4Mix the noodles

Place the cooked noodles into the bowl with the sauce and use chopsticks to mix thoroughly, ensuring every strand is well-coated.
Tip: Use a folding motion to combine the noodles and sauce without breaking the strands. - 5Add chashu slices

Arrange thick, tender slices of homemade chashu pork on top of the mixed noodles as the main protein topping.
Tip: For the best texture, ensure your chashu is sliced thick and served warm. - 6Add garnishes

Complete the bowl by adding a halved soft-boiled egg, followed by a sprinkle of chopped green onions and a portion of bamboo shoots.
Tip: The soft-boiled egg adds a creamy richness that pairs perfectly with the savory sauce. - 7Add the final toppings

Carefully place strips of nori seaweed into the bowl alongside the other toppings. Gently add a fresh, raw egg yolk to the center of the mixture to provide a rich, creamy element that will coat the noodles when stirred.
Tip: If you are concerned about raw eggs, ensure you use high-quality pasteurized eggs for this step. - 8Drizzle with chashu sauce

As the final touch, drizzle a small amount of the thickened chashu sauce directly over the assembled noodles and toppings. This adds a concentrated burst of savory flavor to the dish before serving.
Tip: Go lightly with the final drizzle, as the noodles have already been coated in the base sauce.
