Bring a large pot of water to a boil then add the pasta and cook according to the package instructions.
In a large skillet, heat olive oil over medium-high heat. Once the oil is hot, add the garlic cloves and let sizzle and cook for 2-3 minutes, careful not to burn it. Then add the crushed red pepper flakes. Reduce heat to medium-low.
Once the pasta has finished cooking, drain well then add to the skillet and toss to coat. Add the parsley, cheese, salt, and pepper and toss until well-coated and everything distributed evenly.
