Why This Recipe Works
Mushrooms and bacon are no strangers to pasta, but for even greater savory flavor, we added instant dashi powder and soy sauce to the dish. We began by crisping bacon in a skillet, then removed it and browned a pound of mushrooms in the fat left in the pan (any type or mix of mushrooms will do), followed by scallions and garlic. To finish the sauce, we stirred in some pasta cooking water, butter for silky texture, and the instant dashi powder and soy sauce. Despite only lightly coating the spaghetti, the resulting sauce turns the dish into a flavor powerhouse.
