3 tablespoons butter 
1/2 cup finely chopped shallots 
5 garlic cloves, minced 
2 cups heavy whipping cream 
1-1/4 cups shredded Asiago cheese 
1 cup grated Parmesan cheese, divided 
3/4 cup grated Romano cheese 
1/4 teaspoon salt 
1/4 teaspoon pepper 
1 package (12 ounces) uncooked gluten-free pasta
1. In a large saucepan, heat butter over medium heat. Add shallots; cook and stir until tender, 2 to 3 minutes. Add garlic; cook 1 minute longer. Add cream; cook and stir until heated through. Stir in Asiago, 1/2 cup Parmesan, Romano cheese, salt and pepper; bring to a boil, stirring constantly. Reduce heat; simmer, uncovered, until thickened, about 10 minutes, whisking occasionally. 
2. Meanwhile, cook pasta according to package directions. Drain, reserving 1 cup pasta water; place pasta in a large bowl. Add sauce; toss to coat. Thin as desired with reserved pasta water. Serve with the remaining 1/2 cup Parmesan cheese.
