Ingredients
-
12 ounces pasta (penne or rigatoni work best)
-
1 pound Italian sausage, sliced
-
8 ounces mushrooms, sliced
-
2 tablespoons olive oil
-
1 small onion, diced
-
3 cloves garlic, minced
-
1 cup heavy cream
-
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 fresh parsley, chopped
Instructions
Step 1: Cook the Pasta
Preheat oven to 375°F (190°C). Cook pasta until al dente, drain, and set aside.
Step 2: Brown the Sausage & Vegetables
Heat olive oil in a large skillet over medium heat. Cook sausage until browned, then set aside. In the same skillet, sauté onions until translucent, then add garlic and mushrooms. Cook until mushrooms are tender.
Step 3: Make the Creamy Sauce
Stir in the heavy cream and chicken broth. Let simmer until slightly thickened. Add Parmesan, oregano, thyme, salt, and pepper. Mix well.
Step 4: Combine & Bake
Return pasta and sausage to the skillet, coating everything in the sauce. Transfer to a greased baking dish. Sprinkle mozzarella evenly on top.
Step 5: Bake & Serve
Bake for 20–25 minutes, until the cheese is melted and golden brown. Rest for a few minutes, garnish with parsley, and serve warm.
