Ingredients:
- 1 lb pasta (Spaghetti or Linguine)
- 5 oz fresh baby spinach
- 4 tbsp salted butter
- 1 cup Parmigiano-Reggiano, freshly and finely grated
- 4 large garlic cloves, sliced razor-thin
Instructions:
- Boil a large pot of heavily salted water. Cook the pasta for 1 minute less than the package directions until al dente. Reserve 1.5 cups of the starchy pasta water before draining.
- While the pasta boils, melt the butter in a large skillet over medium-low heat. Add the sliced garlic and sauté until golden and fragrant, ensuring it does not turn dark brown.
- Add 1/2 cup of the reserved pasta water to the skillet with the garlic butter and whisk to combine.
- Transfer the hot pasta directly into the skillet. Add the fresh baby spinach and half of the grated Parmesan cheese.
- Use tongs to toss the mixture vigorously over low heat. The residual heat will wilt the spinach. Gradually add more pasta water as needed until a glossy, silk-smooth emulsion forms and coats the pasta.
