Creamy Baked Fettuccine with Asiago and Thyme

Preheat the oven to 375 degrees F. Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes. Drain pasta reserving 1 cup of the pasta cooking liquid. In a large bowl combine the 2 cups Aiago cheese, creme fraiche, Parmesan , thyme, salt, pepper, cooked pasta, and pasta cooking liquid. Gently toss until all the ingredients are combined and the pasta is coated. Place the pasta in a buttered baking dish and sprinkle with the remaining 1/4 cup asiago cheese . Bake until golden on top, about 25 minutes. Let sit for at least 5 minutes and serve.
