Super-Savory Mushroom Bacon Spaghetti

Instructions

1. Bring 2 quarts water to a boil in a large pot. Add spaghetti and 1/2 tbsp salt; cook until al dente. Reserve 1 cup cooking water, then drain and return pasta to pot.
2. Meanwhile, cook bacon in a 12-inch skillet over medium heat until golden and crispy, 6-8 minutes. Transfer to a paper towel-lined plate.
3. Add mushrooms to the bacon fat in the skillet and cook over medium-high heat until softened and golden, about 5 minutes. Add scallion whites and garlic; cook until fragrant, 30 seconds.
4. Stir in 1/2 cup reserved cooking water, butter, soy sauce, and dashi powder. Transfer to the pot with pasta along with the reserved bacon and toss to combine. Adjust consistency with more cooking water if needed.
5. Sprinkle with scallion greens and serve immediately.
