Instructions
Prep ingredients: Have everything sliced, zested, juiced, and measured out prior to cooking. You will cook the sauce at the same time as the pasta.
Heat pasta water: Add 1 tablespoon kosher salt to a large pot of water and bring to a boil.
Sauté vegetables: Meanwhile, in a large skillet or Dutch oven, heat the 2 tablespoons butter and 1 tablespoon olive oil over medium-high heat. When the butter is melted, add 1 leek to the pan. Sauté, stirring often until the leeks are softened and just starting to brown, about 5 minutes. Add the 1 teaspoon garlic and sauté another minute or two.
Cook pasta: When the salted water comes to a roaring boil, add 1 pound pasta and keep the heat as high as you can without it bubbling over. Cook the pasta according to the package directions (my pappardelle took about 12 minutes). When the pasta is done, dip a measuring cup into the salted pasta water and scoop out 1-2 cups before draining the pasta. This will be used to thin the sauce. Drain the pasta and keep it warm.
Make cream sauce: Add the 2 cups heavy cream to the pan with the leeks. Reduce the heat to medium. Cook until the cream is heated through and starts to bubble around the edges. Add all of the lemon zest and about half of the lemon juice from the 2 Meyer lemons . Stir in the 2 tablespoons fresh basil, 1/2 cup parmesan cheese, and 1/2 teaspoon kosher salt.
Combine pasta with sauce: Add warm cooked pasta to the cream sauce. Stir to coat the pasta. As the sauce continues to heat, it will thicken. Add reserved pasta water, a couple of tablespoons at a time, to thin if needed. Taste and add additional lemon juice and additional salt, if desired.
Serve: Add pasta to serving bowls and top with freshly ground pepper and additional basil and parmesan.
