Ingredients
- 200 g pasta
- 150 g beef strips
- 100 g mushrooms
- 2 cloves garlic, minced
- 1 onsen egg
- 1 tbsp soy sauce
- 1 tbsp oyster sauce
- 1 tsp starch
- 1 tbsp cooking oil
- 2 tbsp black truffle sauce
- to taste black pepper
- optional grated Parmesan cheese
- optional dried herbs
Instructions
- 1Prepare the mushrooms

Remove the stems from the mushrooms and slice them into even pieces, ready for sautéing.
Tip: Wipe mushrooms with a damp cloth instead of washing them to keep them firm during cooking. - 2Slice the beef

Slice the beef into thin strips, which helps it cook quickly and ensures a tender texture in the pasta.
Tip: Slicing against the grain makes the beef much easier to chew. - 3Marinate the beef

In a bowl, combine the beef strips with soy sauce, oyster sauce, black pepper, a little starch, and cooking oil. Mix thoroughly to ensure the marinade coats the meat evenly.
Tip: Adding a little oil to the marinade helps keep the beef moist while stir-frying. - 4Cook the onsen eggs

Carefully lower the eggs into a pot of hot water. Cover the pot and let them cook for 10 minutes before transferring them to an ice water bath.
Tip: Ensure the water-to-egg temperature ratio is correct for that perfect soft-set texture. - 5Sauté the garlic

Heat oil in a frying pan and add the minced garlic. Sauté until fragrant and lightly golden to create a flavorful base.
Tip: Keep the heat medium so the garlic doesnt burn, which can make it bitter. - 6Cook the mushrooms

Add the prepared mushroom slices into the pan with the sautéed garlic. Cook them until they become soft and tender.
Tip: Let the mushrooms brown slightly for a deeper, more savory flavor. - 7Stir-fry the beef

Add the marinated beef strips to the pan alongside the softened mushrooms. Stir-fry over medium-high heat until the beef is fully browned and cooked through.
Tip: Keep the beef in a single layer for a better sear if your pan is large enough. - 8Toss with pasta and sauce

Add the cooked pasta directly into the pan with the beef and mushrooms. Pour in the soy sauce, oyster sauce, and black truffle sauce, then toss everything together until the noodles are evenly coated.
Tip: Add a splash of pasta water if the sauce appears too thick or dry.
