Ingredients

• 7 cups water, plus more if needed
• 3/4 teaspoon fine sea salt, plus more for finishing
• 1 pound dried bucatini (or other long pasta, cooking time adjusted if necessary)
• 4 tablespoons unsalted butter
• 1 tablespoon plus 2 teaspoons za’atar, divided
• 2 teaspoons freshly cracked black pepper
• 4 ounces Parmesan cheese, very finely grated
• 1 ounce pecorino Romano cheese, very finely grated
• 2 teaspoons whole fresh marjoram or thyme leaves (optional)

Directions

• Step 1
• In a deep, wide skillet or Dutch oven over medium-high heat, bring the water to a boil, then stir in the salt. Add the bucatini and cook for 9 minutes (or per package instructions) until al dente, stirring every now and then so they don’t stick together or to the bottom of the pan, and to ensure they are submerged. Add more hot water if needed to keep the pasta covered. Drain, reserving all the cooking water. (You should have about 2 1/4 cups water; if not, add enough hot water until you do.)
• Step 2
• In a large, high-sided, nonstick saute pan over high heat, cook the butter until bubbling, then stir in 1 tablespoon of the za’atar and the pepper and cook, stirring, until fragrant, about 1 minute. Add the reserved cooking water, bring to a rapid boil and cook until silky and slightly reduced, about 5 minutes. Add the pasta and stir vigorously into the sauce. Add the Parmesan in two batches, continuing to stir vigorously as you go and waiting until the first half has melted before adding the next. Once all the Parmesan has melted, add the pecorino, continuing to stir, until it has also melted and the sauce is smooth and silky.
• Step 3
• Transfer the pasta to a lipped platter and sprinkle with the marjoram or thyme (if using), remaining 2 teaspoons za’atar and a small pinch of salt. Serve hot.
