Olive Garden Homemade Alfredo Sauce Recipe

When I found out I had celiac disease and couldn't have fettuccine Alfredo, I was determined to figure out a way to re-create it. I mix this homemade alfredo sauce with gluten-free multigrain pasta, but you can use any style of pasta. —Jackie Charlesworth Stiff, Frederick, Colorado

 3 tbsp butter
 ½ cup finely chopped shallots
 5 garlic cloves, minced
 2 cups heavy whipping cream
 2 ¾ cups shredded Asiago cheese
 1 cup grated Parmesan cheese, divided
 ¾ cup grated Romano cheese
 ¼ tsp salt
 ¼ tsp 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, 2-3 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.

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.
