How To Make Oven-Baked Sausage and Mushroom Pasta Gratin:

Step 1: Prep & Cook Pasta: Preheat your oven to 375°F (190°C). Cook the pasta according to package instructions until al dente. Drain and set aside.
Step 2: Cook Sausage & Vegetables: In a large skillet, heat the olive oil over medium heat. Add the sliced Italian sausage and cook until browned. Remove the sausage and set it aside. In the same skillet, add the diced onion and cook until translucent. Add the garlic and sliced mushrooms, cooking until the mushrooms are tender.
Step 3: Make the Sauce: Pour in the heavy cream and chicken broth, stirring to combine. Let the mixture simmer for a few minutes until it has slightly thickened. Stir in the Parmesan cheese, oregano, thyme, salt, and pepper.
Step 4: Combine & Bake: Add the cooked pasta and browned sausage back into the skillet, mixing everything together. Transfer the pasta mixture to a greased baking dish. Top with the shredded mozzarella cheese.
Step 5: Garnish & Serve: Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and golden brown. Remove from the oven and let it cool for a few minutes. Garnish with fresh parsley before serving.
