Creating an irresistible Baked Penne with Leeks and Mushrooms is simple when you follow these steps:

1. Preheat Your Oven: Preheat your oven to 375°F (190°C).
2. Cook the Pasta: In a large pot, cook the penne pasta according to package instructions until al dente. Drain and set aside.
3. Sauté the Vegetables: In a large skillet, heat olive oil over medium heat. Add the leeks and mushrooms, cooking until softened, about 5-7 minutes.
4. Add Garlic and Herbs: Stir in the minced garlic, dried thyme, salt, and pepper. Cook for an additional 1-2 minutes until fragrant.
5. Prepare the Sauce: Reduce heat to low, and add the heavy cream to the skillet. Stir, allowing it to thicken slightly.
6. Mix in Cheese: Remove from heat and stir in the grated Parmesan cheese until melted and well combined.
7. Combine Pasta and Sauce: In a large baking dish, combine the cooked penne and the creamy leek-mushroom mixture. Toss to coat all pasta evenly.
8. Top with Cheese: Sprinkle the shredded mozzarella and extra Parmesan cheese over the top.
9. Bake: Place in the preheated oven and bake for about 25-30 minutes, or until the top is golden and bubbly.
10. Garnish: Remove from the oven and let cool for a few minutes. Garnish with fresh parsley before serving.
