Bring a large pot of salted water to a boil. Add the penne pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta cooking water, then drain the pasta in a colander.

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

Reduce heat to low and add the Boursin cheese and heavy cream. Stir until the cheese is melted and the mixture is smooth.

Gradually add the reserved pasta cooking water, stirring until the sauce reaches your desired consistency.

Season with salt and black pepper to taste.

Add the cooked pasta to the skillet and toss to coat in the sauce. Cook for an additional 2 minutes to heat through.

Serve hot, garnished with chopped parsley and grated Parmesan cheese.
