Bring a large pot of salted water to a boil. Cook pasta until al dente.
Reserve 1 cup of pasta cooking water before draining.
In a large skillet, toast black pepper over medium heat for 30 seconds.
Add 1/2 cup of reserved pasta water to the skillet and bring to a simmer.
Add cooked pasta to the skillet and toss to coat.
Remove from heat and add grated Pecorino Romano, stirring until cheese melts.
Add more pasta water if needed to create a creamy sauce.
Serve immediately, garnished with extra cheese and pepper.
