Oven-Baked Sausage and Mushroom Pasta Gratin

Few dishes bring the same comfort and satisfaction as a warm, cheesy pasta bake fresh from the oven. Oven-Baked Sausage and Mushroom Pasta Gratin is the kind of hearty meal that fills the kitchen with irresistible aromas and brings everyone to the table before you even call them. With tender pasta, savory Italian sausage, earthy mushrooms, and a creamy sauce topped with bubbling cheese, this recipe delivers rich flavor in every bite.

This dish is inspired by classic American comfort food casseroles but adds a touch of Italian-style flavor. The combination of sausage and mushrooms creates a deep, savory taste that pairs perfectly with a creamy Parmesan sauce. Once baked, the mozzarella melts into a golden layer that adds the perfect finishing touch.

One of the best things about this recipe is how easy it is to prepare. Everything comes together in just a few simple steps, making it perfect for busy weeknights or relaxed weekend dinners. It’s also a fantastic dish for feeding a family or bringing to gatherings, since it can be made ahead and baked when needed.

The pasta absorbs the creamy sauce as it bakes, while the sausage adds richness and the mushrooms bring an earthy balance. The final result is a bubbling, cheesy pasta dish that feels both comforting and satisfying.

• 8 oz mushrooms, sliced

• 2 tablespoons olive oil

• 1 cup chicken broth

• 1 cup grated Parmesan cheese

• 1 cup shredded mozzarella cheese

• Salt and black pepper, to taste

• 1 teaspoon dried oregano

• 1 teaspoon dried thyme

• ¼ cup chopped fresh parsley

Instructions

1. Prepare the Pasta

Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil and cook the pasta according to the package directions until al dente. Drain the pasta and set it aside.

2. Cook the Sausage

Heat the olive oil in a large skillet over medium heat. Add the sliced Italian sausage and cook until browned and slightly crispy on the edges. Remove the sausage from the skillet and set aside.

3. Sauté the Vegetables

In the same skillet, add the diced onion and cook for about 3–4 minutes until it becomes soft and translucent. Add the minced garlic and sliced mushrooms, cooking for another 4–5 minutes until the mushrooms are tender and lightly browned.

4. Make the Creamy Sauce

Pour in the heavy cream and chicken broth, stirring well. Let the mixture simmer for 3–4 minutes until it begins to thicken slightly. Stir in the grated Parmesan cheese, dried oregano, dried thyme, salt, and pepper.

5. Combine the Ingredients

Add the cooked pasta and browned sausage back into the skillet. Toss everything together so the pasta is evenly coated with the creamy sauce.

6. Bake the Gratin

Transfer the mixture to a greased baking dish. Sprinkle the shredded mozzarella evenly over the top. Place the dish in the oven and bake for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden.

7. Garnish and Serve

Remove from the oven and let the dish cool for a few minutes. Sprinkle chopped fresh parsley over the top before serving.
