Step 1: Prep Your Oven and Pan
Preheat oven to 350ºF. Lightly spray a 9×13-inch baking dish with nonstick spray and set aside.
Step 2: Cook the Pasta
Boil the thin spaghetti according to package instructions until al dente. Drain well.
Step 3: Make the Pasta Base
In a large bowl, whisk together the eggs, parmesan cheese, and melted butter. Add the cooked spaghetti and toss until evenly coated. Transfer the pasta to your prepared baking dish, spreading it into an even layer.
Step 4: Add the Creamy Layer
In a separate bowl, mix together the Italian seasoning, minced garlic, softened cream cheese, and sour cream. Spread this mixture gently over the pasta layer.
Step 5: Add the Meat Sauce
Cook your Italian sausage in a skillet over medium heat until browned. Drain excess grease. Combine the sausage with the spaghetti sauce and mix well. Spread this meat sauce evenly over the cream cheese layer.
Step 6: Top with Cheese and Bake
Sprinkle the mozzarella cheese evenly over the entire dish. Bake in preheated oven for 45 minutes, or until the cheese is melted, bubbly, and slightly golden.
Step 7: Rest and Serve
Let the casserole rest for 5–10 minutes before slicing. This helps it set and makes serving easier. Enjoy warm with garlic bread and a side salad!
Storage and Reheating Tips
