This baked ziti boasts four different cheeses, making it comfort food at its very finest. Mozzarella, parmesan, provolone, and creamy Gorgonzola team up with rich Italian tomato sauce, tangy sour cream, sauteed mushrooms, and perfectly al dente pasta. When a pan of this is bubbling in the oven, you know life is about to get really, really good.
Bring a large pot of water to a boil. Add a generous pinch of salt, then add pasta. Cook until barely al dente, about 8 minutes, or about 2/3 of the time recommended on the pasta package directions. Drain.
In a large skillet over medium heat, saute the mushrooms in olive oil until softened, about 6-7 minutes. Add the tomato sauce and bring to a boil. Turn the heat to low and simmer about 15 minutes.
In an 8" x 8" dish, layer half the cooked pasta, then half the tomato sauce. Cover with the provolone slices. Add the sour cream in spoonfuls, then carefully spread into a thin layer. Top with the Gorgonzola cheese. Add the remaining pasta, then the mozzarella cheese. Spread the rest of the pasta sauce over the top, and finally top with the Parmesan cheese.
Cook for 30 minutes or until the cheese is bubbly.
