# How-To Steps:
01 - Bring a large pot of salted water to a boil. Add fettuccine or egg noodles and cook according to package directions until al dente. Drain well and reserve 1/2 cup pasta water for sauce adjustment.
02 - While pasta cooks, heat olive oil and butter in a large skillet over medium-high heat. Add chopped onion and sauté for 3 to 4 minutes until translucent.
03 - Add minced garlic and cook for 1 minute, then stir in sliced mushrooms. Sauté for 7 to 8 minutes, stirring occasionally, until mushrooms are golden brown and release their liquid.
04 - Reduce heat to medium. Add white miso paste, soy sauce, and Dijon mustard to the mushroom mixture, stirring well to coat all ingredients evenly.
05 - Pour in vegetable broth and smoked paprika, scraping the skillet bottom to incorporate browned bits. Simmer for 2 to 3 minutes.
06 - Reduce heat to low. Add sour cream or crème fraîche and stir gently until the sauce is smooth and homogeneous. Do not boil to prevent curdling.
07 - Add cooked pasta to the skillet and toss to coat thoroughly. Add reserved pasta water gradually as needed to achieve a silky sauce consistency. Season with black pepper and salt to taste.
08 - Transfer to serving plates immediately. Garnish with fresh parsley and additional freshly ground black pepper.
