This is not your mom's creamy noodle casserole. After this dish, miso cream sauce will be your new go-to sauce for everything. It only has 3 ingredients, it's perfectly seasoned and creamy, and just thick enough to hold up to a good noodle. The creaminess is complemented by the crunchiness of the peanuts and panko in this casserole and the green onion and cilantro brighten it up. Make this dish gluten-free by replacing the panko with extra peanuts and using gluten-free miso. We think Togarishi-- a Japanese 7-spice blend found at Asian markets-- is worth the buy, but if you cannot find it use Chinese 5-spice.
