Ingredients

• 12 oz penne pasta
• 2 tbsp olive oil
• 1 lb Italian sausage (mild or spicy, casings removed)
• 1 medium yellow onion, diced
• 3 garlic cloves, minced
• 28 oz crushed tomatoes
• 2 tbsp tomato paste
• 1 tsp dried oregano
• 1 tsp dried basil
• 0.5 tsp red pepper flakes (optional)
• 0.5 cup Parmesan cheese, grated
• 1 cup ricotta cheese
• 2 cups mozzarella cheese, shredded
• 2 tbsp fresh parsley, chopped
• 1 tsp salt
• 0.5 tsp black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.

Step 2

Bring a large pot of salted water to a boil. Cook the penne pasta until al dente, according to package instructions. Drain and set aside.

Step 3

In a large skillet, heat the olive oil over medium heat. Add the Italian sausage, breaking it up with a wooden spoon, and cook until browned, about 5–7 minutes. Remove the sausage with a slotted spoon and set aside.

Step 4

In the same skillet, add the diced onion and cook for 3–4 minutes until softened. Add the minced garlic and sauté for another minute, until fragrant.

Step 5

Stir in the crushed tomatoes, tomato paste, dried oregano, dried basil, red pepper flakes (if using), salt, and black pepper. Bring to a simmer and let it cook for 10 minutes, stirring occasionally, to develop the flavors.

Step 6

Return the cooked sausage to the skillet and stir to combine. Taste and adjust seasoning if needed.

Step 7

In a large mixing bowl, combine the ricotta cheese, 1 cup of shredded mozzarella, 1/4 cup of Parmesan cheese, and chopped parsley. Mix until well incorporated.

Step 8

Spread a thin layer of the sausage-tomato sauce on the bottom of the prepared baking dish. Layer half of the cooked pasta on top.

Step 9

Dollop half of the ricotta mixture over the pasta and spread gently. Pour half of the remaining sausage-tomato sauce over the ricotta, followed by a sprinkle of 1/2 cup of shredded mozzarella.

Step 10

Repeat the layers: add the remaining pasta, the rest of the ricotta mixture, and the remaining sausage-tomato sauce. Top with the remaining 1 cup of shredded mozzarella and 1/4 cup of Parmesan cheese.

Step 11

Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 30 minutes.

Step 12

Remove the foil and bake for an additional 10–15 minutes, or until the cheese on top is melted and bubbly.

Step 13

Let the casserole rest for 10 minutes before serving. Sprinkle with additional fresh parsley if desired. Serve warm and enjoy!
