Cook the pasta in boiling salted water according to package instructions until al dente. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add minced garlic and cook until fragrant, about 1 minute.

Add frozen peas to the skillet and cook for about 3-4 minutes until heated through.

Stir in cream cheese, Parmesan, red pepper flakes, butter, and lemon juice. Cook until the cheese melts and the sauce is smooth.

Add the cooked pasta to the sauce and toss to coat evenly. Serve warm garnished with extra Parmesan if desired.
