Preparation Steps

• Cook the spaghetti in a large pot of salted boiling water according to package directions until al dente. Drain, reserving 1/2 cup of pasta water.
• While the pasta cooks, melt the butter in a large nonstick skillet over medium‑low heat. Add the minced garlic and sauté 3–5 minutes, stirring frequently, until fragrant and lightly golden.
• Stir in the chopped basil and spinach, cooking just until the greens wilt, about 1–2 minutes. Season with salt and pepper.
• Add the cooked spaghetti to the skillet, tossing to coat. If the sauce seems dry, add a splash of the reserved pasta water. Mix in the grated Parmesan and adjust seasoning if needed.
• Serve immediately, topped with an extra pat of butter and additional Parmesan if desired.
