Ingredients

• 12 oz pasta (fusilli or penne)
• 2 tbsp olive oil
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 14 oz crushed tomatoes
• 2 tbsp tomato paste
• 1 tsp dried oregano
• 1 tsp dried basil
• 1 tsp salt
• 0.5 tsp black pepper
• 10 oz tuna in olive oil, drained
• 0.5 cup black olives, sliced
• 2 tbsp fresh parsley, chopped (optional)
• 1.5 cups mozzarella cheese, shredded
• 0.5 cup parmesan cheese, grated
• 0.5 cup breadcrumbs

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or a light drizzle of olive oil.

Step 2

Cook the pasta in a large pot of salted boiling water until it is just shy of al dente (about 1-2 minutes less than the package instructions suggest). Drain and set aside.

Step 3

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

Step 4

Stir in the crushed tomatoes, tomato paste, oregano, basil, salt, and black pepper. Simmer the sauce for 5-7 minutes, stirring occasionally to allow flavors to meld.

Step 5

Fold in the drained tuna, sliced olives, and fresh parsley (if using). Cook for 2 more minutes, then remove from heat.

Step 6

Combine the cooked pasta with the sauce in a large mixing bowl. Toss until the pasta is evenly coated.

Step 7

Pour the pasta and sauce mixture into the prepared baking dish. Sprinkle the shredded mozzarella cheese evenly over the top, followed by the grated parmesan cheese and breadcrumbs for a crunchy topping.

Step 8

Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the top is golden brown.

Step 9

Allow the casserole to cool for 5 minutes before serving. Optional: Garnish with additional chopped parsley for a fresh touch.
