Step-by-Step Instructions
- Make the Peanut Sauce Noodles:
- Gently combine fish sauce honey rice vinegar and red pepper flakes in a large pan set over low medium heat stir until the honey melts and blends in. Spoon in peanut butter coconut milk and curry paste whisking constantly until the sauce turns smooth and creamy. If it seems thin do not worry it will coat the noodles perfectly later.
- Prepare the Noodles:
- Bring a pot of water to a rolling boil and cook your fettuccine per the package instructions just until al dente. Drain quickly and shake dry so they can soak up the sauce. Add to the warm peanut sauce in the pan and keep on the lowest heat to avoid reducing the liquid.
- Make the Glaze:
- Pour brown sugar or honey lime juice and white wine vinegar into a small saucepan. Simmer over medium high flame while stirring until it thickens slightly and takes on a glossy look. Turn off the heat and cover to retain moisture.
- Sear the Fish:
- Pat your fish fillets dry with paper towels and sprinkle on salt and pepper to cover both sides. Heat a skillet over high until it is almost smoking hot. Drizzle in the olive oil which should sizzle the second it hits the pan then lay in the fillets without touching each other. Sear two minutes per side so the fish forms a golden crust but stays tender inside.
- Assemble and Serve:
- Scoop a generous mound of noodles onto the center of each plate. Gently set the seared fish fillet overtop then drizzle with a good share of the lime glaze. Dust with chopped green onions and serve immediately for best texture and warmth.

Black cod is my personal favorite ingredient here because it always turns out buttery and never dry no matter how I prepare it. The first time I cooked this for my family was on a chilly evening and now it always feels like a special treat when I bring it to the table.
Storage tips
Store leftovers in an airtight container in the fridge for up to two days. Reheat gently in a skillet with a splash of water to loosen up the noodles and keep the fish delicate. The glaze can be stored separately in a small jar and spooned on just before serving.
Ingredient substitutions
Any firm white fish works well such as tilapia halibut mahi mahi or sea bass. For the noodles you can swap in rice noodles or even spaghetti if that is what you have. Almond butter is a good stand-in if you are out of peanut butter though it will taste a bit different.
Serving suggestions
Serve this dish with a quick cucumber salad or lightly sautéed bok choy for a contrast in texture and added freshness. Garnish with extra lime wedges and a scattering of toasted peanuts if you like crunch.
