Begin by preheating your oven to 375°F. and mixing the cheeses with seasonings to create a rich, flavorful filling. Layer the lasagna noodles with the cheese mixture and sauce, then bake until golden and bubbly.
If you’re using traditional noodles, cook them according to the package instructions until al dente, then drain and set aside. For no-boil noodles, you can skip this step.
In a large bowl, combine the ricotta, mascarpone, half of the grated Parmesan cheese (save the rest for topping), salt, pepper, and the beaten egg. Stir in the torn basil leaves. This is your cheese mixture.
Spread a thin layer of red sauce on the bottom of a 9×13-inch baking dish. This will prevent the noodles from sticking and give the first layer of pasta something to cozy up to.
