Start by bringing a large pot of salted water to a boil.

Add the pasta and cook according to package instructions until al dente, about 8-10 minutes.

While the pasta cooks, heat the olive oil in a large skillet over medium heat.

Add the minced garlic and red pepper flakes to the skillet, sautéing for about 30 seconds until fragrant.

Stir in the asparagus pieces and cook for 3-5 minutes until tender but still crisp.

Once the pasta is cooked, reserve a cup of pasta water, then drain the pasta.

Add the hot pasta directly to the skillet with the asparagus.

Add the grated parmesan cheese, reserved pasta water, and a squeeze of fresh lemon juice.

Toss everything together until the cheese melts and coats the pasta evenly.

Season with salt and pepper to taste and serve immediately.
