1. Boil Water: Fill a large pot with water, add a pinch of salt, and bring it to a boil.

2. Cook Pasta: Add the penne to the boiling water and cook according to package instructions until al dente. Stir occasionally to prevent sticking.

3. Heat Oil: While the pasta is cooking, heat the olive oil in a large skillet over medium heat.

4. Sauté Garlic: Once the oil is hot, add the minced garlic and sauté for about 1-2 minutes until it’s fragrant but not browned.

7. Season: Taste the sauce and season with salt and freshly ground black pepper according to your preference.

8. Combine Pasta and Sauce: When the penne is done, drain it and add it directly to the sauce in the skillet. Toss well until the pasta is evenly coated.

9. Plate and Garnish: Serve immediately, garnishing each plate with fresh parsley or basil. Optionally, sprinkle grated Parmesan cheese on top.
