Ingredients
1 (16 ounce) box dry fettuccine pasta
1 ¼ cups butter, divided
1 pint heavy whipping cream
¾ cup grated Romano cheese
½ cup grated Parmesan cheese
3 cloves garlic, crushed, divided
salt and ground black pepper to taste
2 tablespoons olive oil
1 large onion, chopped
8 ounces diced mushrooms
1 (8 ounce) package frozen shrimp, deveined and tails removed, thawed
Directions
Fill a large pot with lightly salted water and bring to a rolling boil over medium heat. Stir in fettuccine, return to a boil, and cook until tender yet firm to the bite, about 8 minutes. Drain and keep warm.
While the fettuccine is cooking, heat 1 cup butter and cream in a large saucepan over medium heat. When butter melts, add Romano, Parmesan, 1/3 of the garlic, salt, and pepper; cook and stir until cheese melts and sauce thickens, about 5 minutes. Remove from the heat.
At the same time, heat remaining 1/4 cup butter and olive oil in another saucepan over medium heat. When butter melts, add onion; cook and stir until softened and translucent, 2 to 3 minutes. Stir in mushrooms and remaining garlic; increase the heat to medium-high and cook until mushrooms are soft, about 2 minutes. Add shrimp and cook until bright pink on the outside and opaque in the center, 1 to 2 minutes.
Fold shrimp mixture into sauce. Add drained fettuccine and toss to coat.
