Ingredients

• 12 oz spaghetti
• 3 cups cooked chicken or turkey (shredded or diced)
• 2 tbsp olive oil
• 1 medium yellow onion (diced)
• 3 garlic cloves (minced)
• 28 oz canned crushed tomatoes
• 2 tbsp tomato paste
• 1 tsp dried basil
• 1 tsp dried oregano
• 1 tsp salt
• 0.5 tsp black pepper
• 0.25 tsp red pepper flakes (optional)
• 2 cups shredded mozzarella cheese
• 0.5 cups grated Parmesan cheese
• 2 tbsp fresh parsley (chopped, for garnish)

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 boil and cook the spaghetti according to the package directions until just al dente. Drain and set aside.

Step 3

In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened. Add the minced garlic and cook for an additional 1 minute until fragrant.

Step 4

Stir in the crushed tomatoes, tomato paste, dried basil, dried oregano, salt, black pepper, and red pepper flakes (if using). Bring the sauce to a simmer and let it cook for 8-10 minutes, stirring occasionally.

Step 5

Add the cooked chicken or turkey to the tomato sauce, stirring to combine. Remove the skillet from heat.

Step 6

In a large mixing bowl, combine the cooked spaghetti, tomato sauce mixture, 1 cup of shredded mozzarella cheese, and 1/4 cup of grated Parmesan cheese. Toss until well-coated.

Step 7

Transfer the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining 1 cup of mozzarella cheese and 1/4 cup of Parmesan cheese evenly over the top.

Step 8

Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly. If desired, broil for the last 2-3 minutes to achieve a golden-brown top.

Step 9

Remove from the oven and let the casserole rest for 5 minutes before serving. Garnish with fresh parsley and serve warm.
