Cacio e Pepe Pasta with Peas

Bring a large pot of water to a boil. Add pasta and peas and cook until the pasta is just tender, 3 to 4 minutes. Reserve 1 1/2 cups cooking water and drain the pasta and peas.

Combine pecorino and Parmesan in a small bowl.

Heat butter and oil in a large skillet over medium heat. Add pepper and salt and cook for 1 minute. Carefully pour in 3/4 cup of the cooking water and simmer until slightly thickened, about 2 minutes. Add the pasta and peas; remove from heat.

Slowly stir in 1/2 cup of the cheese mixture. Toss, adding more of the cooking water as needed, until well coated, about 2 minutes. Serve with the remaining 1/2 cup cheese and more pepper, if desired.
